The function of a three-way valve
A three-way valve’s function, which is ultimately dictated by the system’s overall goal, is to divert, mix, or separate the working flow or media.
It is utilized in the water supply, ventilation, cooling station, and boiler room piping systems.
Comprehending the function of three-way valves in insulation and heating systems is crucial to comprehending their operation. These valves control the flow of hot water, sending it back to the boiler for reheating or to the heating system. They maximize energy efficiency and guarantee even heating throughout your house by managing this flow. It is essential to comprehend how they work in order to maintain effective insulation and heating, which will ultimately save you money and improve comfort. Therefore, understanding the subtleties of three-way valve operation can yield big benefits for your home or clients, whether you’re a homeowner or a heating specialist.
Design and operation of the three-way valve
Three openings, or ports, make up a valve. An outlet can be used for one purpose only, an inlet for another, or both.
The three-way valve operates on the following principle: the working flow enters the inlet hole or holes, and the gate inside the valve controls the valve’s subsequent direction.
The three types of valves are ball, cone, and cylindrical valves based on how they operate. The shutter is attached to an external actuator or handle, which rotates to move the shutter. Cone plugs have a gap between the plug and the seat, and ball and cylindrical plugs have a hole in the plug that allows the working flow to pass through.
In certain cases, check valves are incorporated into the three-way valve’s design to stop the working medium from backing up because of pressure variations in the system’s connected pipes.
Types and features of three-way valves
Three-way valves fall into three categories: switching, mixing, and separating, based on their mode of operation and impact on the medium.
A switching valve is used in the event that the direction of the medium within the system needs to be altered. One pipe is closed and the other is opened when the knob is turned to rotate the valve. The direction of the medium’s movement changes.
Use the three-way control valve if the task at hand requires more complexity, such as splitting or combining the working flow. The "one inlet – two outlets" installation concept is used. The "two inlets – one outlet" principle is applied when the task involves mixing flows, such as when maintaining the working flow’s temperature at a specific value.
Three-way valves are classified into two categories based on how they operate and are controlled: those that are operated manually and those that are operated using a variety of actuators.
Manual operation suggests that the valve gate is moved by hand. These valves operate with simplicity and dependability.
In more intricate designs, the gate position is controlled by electric actuators, and thermostatic valves use thermocouples as actuators that alter the gate’s position in response to changes in the medium’s temperature.
These valves can be utilized in automatic control systems, such as those that keep heated objects at a predetermined temperature.
Due to the more complex design, such valves have lower reliability.
The existence of abrasive particles in the working medium also has an impact on the dependability of any valve design. The valve’s service life is shortened as a result.
The valves are made of materials that are customary in the pipe fitting industry. Cast iron, brass, bronze, and stainless steel are used to make them. The temperature, operating pressure, and aggressiveness of the medium all influence the material selection.
The tightness of the valve’s construction is one of its key characteristics.
Seals inside the valve guarantee its tightness. They are separated into two categories: tension packing (steel on steel, fluoroplastic, special rubber on steel, etc.) and gland packing (typically fiber materials, such as flax, hemp, and lubricated).
Detachable flange and coupling as well as non-detachable connections under welding are used to connect the valve to the pipe. Split connections have the benefit of being repairable, but they also have the drawback of having less sealing than non-split connections. In systems that are prone to leaks, valves with welding connections are employed.
Three-way mixing valve
It’s common knowledge that heating the water for the radiators is the most efficient method of conserving energy. It is impossible to completely rule out a failure in the heat balance, even if all heat losses are taken into account and the heating circuit is set up in accordance with the thermal calculation data. Installed in the mains to ensure prompt response to the aforementioned processes is a three-way mixing valve.
It can be used for floor heating as well as traditional radiator heating. This kind of valve makes sure that flows from heat carriers with various temperatures are mixed together. To achieve the necessary temperature barrier, this is required. The ability to reroute or disperse the heat transfer fluid flow. shielding coatings from potential heat overload.
Three-way thermostatic valve
In DHW systems, a three-way thermostatic mixing valve is used to maintain the hot water’s temperature at the desired level and to guarantee the seamless operation of the underfloor heating system.
The three-way thermostatic valve’s ability to prevent burns is one of its key features. The valve will automatically cut off the hot water supply if the cold water stops abruptly.
Every valve has a unique handle that can be used to adjust the temperature to the desired level and react quickly to variations in water pressure and temperature. There have already been developed versions of valves with an integrated non-return valve.
Units of various types of systems are separated and mixed using three-way thermostatic valves. A manual handle or an electric actuator can be used to turn this kind of valve. This kind of valve is marketed as a sanitary fixture that can mix streams of varying temperatures to heat the liquid to a desired degree. The final temperature at the outlet can be obtained by varying the ratio of these flows.
Such a valve has four ways in addition to three. The carrier’s temperature will drop in the first version, and separate regulated circuit creation will be possible in the second.
Three-way valve for underfloor heating
The "water floor heating" heating system differs greatly from the traditional radiator heating system. The main point is that, unlike radiators, heating circuits located on the concrete screed floor do not require as high of a medium temperature. Low temperature systems, also known as warm floors, can be connected through heating devices or by connecting hot water to the mixing unit’s source.
The water temperature coming from the water circuit’s heating source must be drastically lowered in order to achieve heating that complies with sanitary standards. A thermostatic three-way valve handles this task.
When choosing a three-way valve, it is necessary to consider a number of characteristics related to the operation of the boiler and the fittings that regulate this operation.
The following characteristics can influence the choice:
Capacity values;Operating parameters of the heat carrier. They are prescribed to the documents that are attached to the boilers. Usually the optimal temperature of the "return" does not exceed +45-50C.Actuator type. It is an important energy-independent three-way mixing valve, which has a mechanical regulator. This is used to ensure the temperature stability of the heat transfer medium. The heating intensity of the room is not taken into account in this case.
You can also choose and electronically controlled device, which will provide the ability to set the heating parameters in each room in the room. Such dampers are extremely sensitive to temperature variations in the room itself.
A three-way valve is a crucial component of contemporary pipe systems, serving a variety of functions and operating media.
