Types of gas taps

Gas pipeline locking devices come in a wide range of configurations. Based on the characteristics of their designs, two primary groups can be identified:

Variety #1: cork

The most popular type of gas for gas up until recently. A conical component with a hole, called a cork, sits at the center of these models.

The central hole in a cone-shaped insert serves as the cork crane’s main organ. It facilitates the opening or overlap of the gas stream. Cranes made of cast iron or brass are robust and resistant to material corrosion and wear.

The hole in the conical portion of the device is combined with the same hole in the pipe when it is opened with a mossy, allowing gas to pass to the equipment. An oil seal is typically used to join cork valves with a pipeline to create tightness.

Variety #2: ball

A robust metal sphere serves as the primary feature of this kind of locking element. Similar to cork counterparts, it features a hole that, when combined with the pipe, guarantees that natural fuel is allowed to reach the associated device when the handle is turned.

The ball crane’s design consists of a spherical component that covers the gas outlet when it’s closed and permits the flow to pass through in an open area.

Comparable valves have just lately become commonplace because of their many benefits, which include:

• low cost;
• excellent functionality and margin of strength;
• long service life;
• simplicity in operation;
• the ability to work in different medium at temperatures from -60 to +80 ° C.

Experts currently prefer ball structures when equipping household gas systems because of their combination of valuable qualities.

Welded valves are disposable and cannot be repaired, in contrast to coupling and flange models that can be used repeatedly.

There are various subspecies of ball valves that vary in how they connect to pipes:

• Threaded (coupling). In this case, the crane is connected to the segment of the gas pipeline using a part with the applied thread.
• Flanger. Fasteners are carried out using flanges fixed by bolts. Such devices are most often used in the transportation of gaseous substances and oil.
• Welded. In this case, the tap is firmly welded with the pipe using the corresponding apparatus.

Ball valves are categorized into three types based on their intended uses:

• Three -way, used for redistribution of gas flows;
• With a heated case used in a cold climate;
• With leakage control.

Additionally, there is a division based on the passage’s diameter. This indicator suggests that the details fall into two categories:

• DN 10-50 mm;
• DN more than 50 mm.

A different classification considers the nominal pressure the crane can withstand. Two categories of devices are distinguished in this instance:

• PN 1.6 MPa 16 kg/cm2;
• PN 4.0 MPa 40 kg/cm2.

Various metals can be used to make ball valves. The most common materials are brass, zinc, steel, and alloys (09g2s, 12x18n10t), as well as plastic.

Brass gadgets that can be yellow or silver in color (the latter being typical of nickelized models) exhibit the best attributes. These alloy devices have a comparatively large weight.

Brass or bronze gas cranes are known to be the most resilient to wear and external forces. These characteristics of a device are its small size, dependability, simplicity of use, and high working resource.

Book cranes with a dependable universal structure can be installed in any position, are long-lasting, and require little upkeep.

Safety rules for work

Any manipulation involving gas equipment is subject to a higher degree of risk. The gas leak happens because the pipe is opened while doing maintenance on the gas pipeline. Two very real risks could result from this:

• Natural fuel is mixed with air, as a result of which an explosive mixture forms. Any spark that can occur when the electrical appliance is turned on (for example, a switch) can lead to an explosion.
• With a greater concentration of gas, the air becomes unsuitable for breathing. Inhalation of the proparic-butane mixture causes poisoning of the body, which can even lead to death.

Strict observance of precautions is required to prevent emergency situations. When fixing equipment, especially replacing a crane, city gas service employees are required to abide by the "Rules for the technical operation and requirements of labor safety in the gas economy of the Russian Federation." (Gosgortekhnadzor of Russia Resolution PB 12-368-00, 18.07.00 No. 41, SNiP 2.04.08-87)

The "Rules for the technical operation and requirements of labor safety in the gas economy of the Russian Federation" (PB 12-368-00 Resolution of the Gosgortekhnadzor of Russia of 18.07.00 No. 41, SNiP 2.04.08-87) must be followed by city gas service employees when fixing equipment, especially when replacing a crane.

It is strictly prohibited to manipulate any gas equipment outside the apartment, whether it be in the entrance or on the street, while the equipment is being repaired.

The following guidelines must be followed when working independently:

• All work must be carried out with windows open wide open.
• The apartment should be completely de -energized, so it is important for repairs to have access to the shield and automatic machines.
• During manipulations to replace the gas crane in the room, it is forbidden to smoke, light matches.
• All work must be carried out exclusively in the daytime.
• The door to the kitchen where work is carried out should be tightly closed. It is also advisable to plug all the cracks to avoid gas entering other rooms.
• It is forbidden to block the valve on a common gas riser, since in this case the gas leak can increase many times, which will increase the danger of an explosion.
• It is advisable to carry out all the work together: this will accelerate the process and avoid complications.
• The crane should not be engaged in self -replacement if signs of corrosion or other damage are observed on a gas pipeline, in which case it is preferable to call specialists.

It is best to have a fire extinguisher (or other fire device) nearby while doing work.

Camping crane audit without replacing it

If the plug-in device is cleaned and lubricated, it may be possible to avoid replacing the valve in certain situations.

In this instance, the sequence of events is as follows:

• First of all, you need to block the crane by installing its handle perpendicular to the pipe on which it is located.
• One of the gas keys to fix the drive in the valve area, trying to further hold it in a motionless state.
• With the help of the second key, drive a clutch and a locknut on a long thread.
• Try to unscrew the valve with a key, and then, with free rotation, unscrew it to the end by hand.
• After removing the part, cover the formed holes with a plug. You should not be afraid of increased pressure, since the pressure in the pipe is only 3-5% higher than atmospheric.
• Put a plug on the thread, then tighten it to the end without helping the tools.
• Unscrew the valve from the catch, removing the layers of old insulating materials and paints.
• Unscrew the plug with a groove on the back of the valve, taking out the spring hidden under it, and then remove the conical plug from the case.
• Carefully clean the details (plug, case) from the remaining old lubricant, and then apply a new composition to the element.
• After that, collect all the details of the gas valve in the sequence opposite to the above algorithm.
• Remove the plug and put the assembled part instead, having previously replaced insulating materials on the thread.
• Screw up the drive and insulate the thread, and then install the countrogike and the coupling in the working position.

In every situation, once the crane replacement is complete, it is essential to verify that the right assembly was made before calling in experts.

The process of installing ball clutch crane

Even you can assemble the crane. You must first clear the hose of debris and dust in order to accomplish this. The gas supply valve must be closed all the way before that. By the way, it’s best to avoid installing such a crane if the pipe is subjected to vibration at least occasionally. If not, we go on.

Select a linen thread that is wide enough. It should lie inside the pipe when twisted. The length of it is 1.5 times longer than the thread’s turns. After twisting the thread, unscrew it from the beginning about 7 centimeters and insert it into a hollow. Turn it clockwise on each hollow after that. The second layer extends from the winding’s end to its starting point. Continue wrapping the thread in a clockwise manner.

Apply a coat of sealant that you had previously mixed, then use your hand to cover the crane’s parts. If everything went according to plan, the gadget ought to be wrapped twice. It needs to be twisted with a wrench.

Brass is the ideal material for the tap. Its working resource is high, its dimensions are small, and its mass is small. In terms of design, it is dependable and adaptable. Such a crane can be installed in any orientation and requires little maintenance. The gas flow is served, it overlaps very tightly, and it can flow in any direction.

There’s a lot of operational resource in this device. The material is forged brass. The substance poses no risks to the environment, human health, or pipelines. Salnikov is the maker of the seal. It is simply adjusted by a nut located beneath the apparatus handle. Here, I also utilize Teflon movable seals. If the system passes, all you need to do is tighten the nut. For a very long time, the sealant will press and help you. The structure’s resource has reached 20,000 cycles.

Because the rod is fixed inside the case, the system is regarded as totally safe. In order to prevent him from flying out, even if you fully unscrew the nut. When the pressure is higher than what is working, the explosion is likewise excluded.

These pieces of equipment last a very long time and don’t require maintenance or lubrication. Even over an extended service life, leakage can be excluded thanks to tightness. Its lever can be turned ninety degrees, which is sufficient to close or open the system.

When it comes to heating and insulating your house, safety must always come first. Replacing a gas crane is a task that requires careful consideration of security regulations, precise instructions, and a keen eye for typical mistakes. This post explores the essential procedures needed to replace a gas crane safely, pointing out potential dangers and providing helpful advice on how to avoid them. With safety as their top priority, homeowners can confidently tackle this task by knowing the correct procedures and being aware of common mistakes.

Analysis of typical installation errors

Even though replacing the gas crane is a fairly simple operation, inexperienced masters run the risk of it not working.

Use extension cords with an internal and external thread if the length of the old crane does not match the same parameter of the new one.

Common flaws include:

• The impossibility of connecting a crane with a pipe. Most often happens due to the fact that these elements do not correspond to their dimensions or thread. Refusers and extension cords of different shapes and sizes will help to fix the situation. In order not to get into such a situation, it is advisable to take into account the parameters of the pipes at the stage of choosing a crane.
• Non -switching of the valve. The thread should be fixed manually, but at the end it is necessary to use the wrench. If this is not done, the connection will not be reliable enough, which will lead to a gas leak and the instability of the structure.
• Twisting the crane exclusively with a wrench. When working, the tool increases the possibility of damage to the part or breakdown of the thread.
• Insufficient tightness of the connection. If the check of the replaced crane shows that natural gas enters the air, immediately turn off the plate and correct the error as described above.

Never operate low-quality cranes.

Using models of well-known companies is crucial if you want the technique to last for a long time. It is best to use brass devices that are highly durable and efficient with little need for maintenance.

Materials such as silicone start to lose their elasticity and dry out, which causes them to start missing gas. It is preferable to use lubricants based on graphite to stop this from happening.

Manufacturers

One of the most crucial systems for housing provision is the gas pipeline.

Thus, extra care must be taken when selecting all of its components, including shut-off valves.

It is preferable to only buy goods from reputable, established producers.

You can specifically choose to favor cranes made by Italian businesses like:

Valtec’s Italian crane

Additionally, the following companies’ products differ in terms of quality:

• Dungs – Germany;
• Profactor – Germany;
• Broen Ballomax – Poland;
• EFAR – Poland;
• LD – Russia.

Counseling! Since there is a lot of cheap reinforcement from China on the market that occasionally does not meet the requirements for gas shut-off valves, you should avoid purchasing the cheapest gas crane.

Types of ball gas cranes

The variations lie in the installation technique in addition to the locking reinforcement under consideration being identified by a diameter. Gas pipelines typically employ the following kinds of devices:

Threaded (coupl)	They have a small diameter. As a rule, these products are used in household gas pipelines. The connection to the pipeline, as it is not difficult to guess from the name, is carried out using a threaded connection.
Flange	Used in external gas pipelines of large diameter. The connection is carried out by the flange method using bolts. Like threaded ones, these devices are collapsible, t.e. they can be dismantled and then installed in place.
Welded	Like flange, used for external gas pipelines. Their diameter can be from 10 to 70 millimeters. The connection to the pipeline is carried out by welding. Accordingly, this installation option is non -graceful.The advantages of such products include complete tightness and high reliability. In addition, welded shut -off valves does not require maintenance, t.e. Pastens of flange connections.

Counseling! There are cork valves in addition to the ball of locking valves. They are, however, used much less frequently these days due to their lower durability and dependability.

Swelded locking reinforcement is seen in the picture.

Peculiarities

Thus, gas pipelines have recently begun to use unique ball valves. These gadgets are made to open up a gas stream or to fully overlap one. These devices are unique in that their locking mechanism is shaped like a ball with a through hole in it. Furthermore, the diameter hole matches the pipeline’s diameter (also refer to the article "Where and How the High-Pressure Crane Is Used").

The ball must be rotated 90 degrees in order to cover the flow, with the hole positioned perpendicular to the pipeline. Lever control is used to operate the control mechanism. Rings composed of supple and robust materials offer tightness.

Differences from tap valves

I have to admit that the gas tap and the water tap differ externally in that the lever is yellow in color rather than red.

There are numerous additional structural variations.

• Have a more durable case, which is made of special varieties of steel or brass with a high copper content.
• Have a longer connecting thread.
• The shut -off mechanism is made of a particularly durable chrome or nickel material.
• The rod is made of durable polymer material.
• These cranes can withstand greater pressure than tap.
• The sealing rings are more durable and provide better tightness.

Reinforcement of baspery

Take note! Even though gas cranes are more expensive, water supplies cannot take their place because the savings would be substantial. However, using gas shut-off valves rather than taps is acceptable.

The tightness level of the gas crane is generally higher than that of the tap-on-end valves. The remainder of the time in home gas pipelines is not as significant. Thus, any crane that fits into tightness class "A" can theoretically be used for the gas pipeline.

Gas shutoff

Features of application

Gas pipeline shut-off valves are typically found in the kitchen, or anywhere gas-powered equipment is used. Moreover, a different valve is installed for every consumption source.

For instance, I install separate gas cranes for plates and other devices in homes and apartments that have gas stoves, speakers, or boilers installed. Furthermore, a single common valve is frequently installed at the input, enabling total blockage of the gas supply.

It is important to note that shut-off valves are used for more than just stopping flow; for instance, a gas three-way crane lets you move flow from one pipeline to another. It is true that these gadgets are not utilized in daily life.

Counseling! Since a valve that allows you to block the gas is always mounted on the cylinder, total shut-off valves cannot be installed when selling gas supply to a house using spine gas.

Innovative solution gas ball ball

Since its recent introduction to the market, ball gas cranes have proven to be a dependable option for gas pipeline overlaps. Consequently, he became very well-liked by customers. Among the unique qualities, the following should be mentioned:

• – high service life;
• – simple design;
• – excellent performance;
• – Low cost.

Ball gas cranes are spherically shaped locking devices that cause constipation. They have a unique hole made for letting gas out and shutting it. It is possible to rotate the shutter on its axis. The location of it is opposite the pipeline.

The device’s long lifespan and dependability are made possible by its relatively simple design. She made a great impression on customers and is becoming more and more well-known.

The best steel varieties are used to make ball gas taps. It is usable in temperatures ranging from -60 to +200 degrees Celsius.

The surroundings don’t matter. It has the potential to be hostile as well as feeding. Comparatively speaking, this type of crane is already far more common than devices that are conical or cylindrical.

The procedure for calling specialists

The best option is to contact Gorgaz staff rather than try to do it yourself. In this instance, the process is as follows:

• You need to contact the company’s service house, tell in detail about the problem and leave an application for a call call (it is better to refrain from using gas before his visit).
• At the appointed time, employees of the company will come to the apartment who will perform diagnostics and solve the issue of replacing the crane. They will also tell you which valve model can be purchased independently or offered to use the option that has it.
• Since Gorgaz specialists can ask them to present a gas supply agreement, documents for a gas stove or the last paid gas bills, it is better to prepare them in advance.
• Before the visit of workers, it is also advisable to light blue fuel and let it burn out in the pipe blocked his supply with a tap with a gas meter. Such an operation will help save time, since all manipulations can only be carried out after the devastation of the pipeline.
• It is also necessary to ventilate the room well by arranging a draft.
• When carrying out work by gallows, it is advisable to be next to them to control their work.
• After replacing the device, along with the repairmen, conduct a check by carrying out a trial inclusion of the burner.
• Experts fill out the act on the operation, assuring it by the seal of the service organization. The owner of the apartment also signs paper.
• After all the work of the window, the window should be left open at least for at least half an hour so that all the gas is taken out of the room.

The service of removing the old shut-off mechanism and installing a new crane model is provided free of charge in the event that scheduled work on the replacement or repair of gas systems occurs; however, the apartment owner is responsible for purchasing the device and any consumables.

A repair team of two people typically performs crane replacement services, so the process requires some time.

You will also be required to pay for the device and a nominal fee for the services rendered when contacting specialists.

Common reasons for the replacement of the crane

Gas communications are incredibly dependable, lasting for decades even in harsh environments. The most susceptible component of these systems are the apartment’s installed valves, which rapidly malfunction from continuous loads.

The short lifespan is particularly prevalent in gas valve models constructed of cheap alloys or plastic, as well as in outdated structures.

If there is a gas smell in the crane area, it may be time to replace a locking mechanism. External damage, such as chips or cracks in the device, as well as challenging movement or excessively free rotation of the flywheel, are additional indicators of the device’s malfunction.

If any of the issues listed above arise, they should be the result of work done by Gorgaz or another company that services your house. They will perform diagnostics, suggest a model of crane that would be appropriate, and replace the operation if needed. Experts recommend replacing the crane until the defects manifest immediately after the warranty period, which is 10 years for the majority of models, due to the increased risk.

The main points for the selection of the device

Some features to consider when selecting a locking mechanism for the gas pipeline are as follows:

• Pipe diameter. The crane must completely block the flow of gas flow into the apartment. If the shut -off element is not not approaching the walls of the pipe, then its tightness will only be partial, which can lead to severe consequences.
• Coincidence of the diameter and pipe of the pipe and tap. In this case, the installation of the device is performed quite easily. Installation of a shut -off element with a non -consuming thread and diameter in principle is possible when using adapters, however, this will require additional material and time costs for the acquisition and installation of additional details.
• The integrity of the case. Cracks, chips, influxes and other defects should be absent on the outer shell of the element. Their presence indicates a violation of the rules for transporting, manufacturing or storing parts, which is why internal malfunctions are possible, as well as a reduction in the operation period.

Additionally, the product’s quality should be considered, with a preference for well-known companies’ models.

How the taps differ

Therefore, specialized ball valves are used in gas pipelines these days. These tools are required to either fully close or partially open gas. These devices are characterized by a locking mechanism that is spherical in shape and has a through hole in it. Additionally, the diameter of the hole converges with the collector’s diameter.

The ball must be rotated so that the hole is perpendicular to the pipeline—that is, it must be expanded by 90 degrees—in order to cover the flow. A lever is used to operate the locking mechanism. Rings composed of soft, premium materials provide the impermeability.
