What is the function of the three way control valve for each group of heaters?

The three-way control valve mainly controls the displacement change of the valve through the output thrust of the straight stroke, and then can achieve the function of accurately controlling the process parameters of the fluid medium.

Three-way valve. There are three entrances and exits connected to the pipeline, which is equivalent to two single-seat valves in one. According to the function, it is divided into a merging valve (two inlets and one way) and a divert valve (one inlet and two passes).

When working, all the way is fully open and all the way is closed, so the force is similar to that of a single-seat valve when closing, and the unbalanced force is large. The spool of the three-way valve is the same as the sleeve of the sleeve valve, and its interception area has two types: opening a large window and making a small hole (jet type), and the latter has the function of reducing noise and resonance.

Splitting Controls the room temperature by adjusting the amount of hot water that passes through the heat sink.

Many people now have heating in their homes, which can bring warmth to the family home during the winter months. The use of heating is regulated by a three-way control valve, so how to use the heating three-way control valve? What should I pay attention to when installing the heating three-way control valve?

How to use the heating three-way control valve.

First find the letter marks of "S" and "O" respectively, and then rotate clockwise in the direction of "S" to reduce the water inlet, if you rotate one circle, you will turn off the water intake, and if you rotate counterclockwise in the direction of "O", you will increase the water inlet, and rotate one circle to completely open the water intake.

What to pay attention to when installing the heating three-way control valve.

1. According to Qeeka Home experts, before use and installation, you need to carefully understand the installation specifications, and install them on the premise of cutting off the power supply.

2. During installation, it is necessary to ensure that the direction of the water flow of the pipeline is consistent with the direction marked on the valve.

3. When installing the control valve, it is necessary to ensure that it is located on the upper side of the water tray, so as to ensure that once there is water leakage, the water droplets will fall into the water tray.

4. When the regulating valve and its driving tremor are installed, there should be a proper activity space to facilitate maintenance after the day.

5. When installing accessories, you need to follow the installation process, and do not install the driver prematurely.

6. Wait until the installation of the control valve is completed, and wait until the heating balance front pressure test is passed, and then the driver can be installed.

7. If the driver has been installed in advance, then in the debugging species, do not use too much force, and do not apply too much force to the driver, so as not to cause damage to the driver.

Before using the three-way control valve, you need to clarify the meaning of each letter and operate it in accordance with the requirements of the specification. If you do not know how to use it, it is recommended to consult a professional in time.

Dear, hello, I am glad to answer for you: the switch description of the heating disturbance ant three-way valve Answer: Dear, facing the radiator valve, counterclockwise rotation of the radiator valve is open, clockwise twisting of the radiator is off (turning the radiator valve to the left is open, turning the radiator valve to the right is slowly buried is closed, and some radiator valves are above"+"or"-The plus side is open, the minus side is off, and the radiator is an arrow, and the arrow side is open, and the twist to the reverse side is naturally closed.

Installation method of heating three-way valve:

1. Inspection before installationBefore installing the three-way control valve, the product quality of the three-way control valve should be checked, starting from the appearance inspection, and then checking whether the parts and accessories are lost during the transportation process, whether there is a certificate, and if necessary, the static characteristics of the inspection or special inspection.

2. Installation principle.

1) The installation position of the three-way control valve requires a certain height from the ground, and a certain space should be left on the upper and lower sides of the valve for the disassembly and repair of the valve. For control valves equipped with pneumatic valve positioners and handwheels, it must be easy to operate, observe and adjust.

2) The three-way control valve should be installed on the horizontal pipeline, and perpendicular to the pipeline up and down, and generally supported under the valve to ensure stability and reliability. For special occasions, when the control valve needs to be installed horizontally on a vertical pipeline, the control valve should also be supported (except for small diameter control valves). During installation, it is necessary to avoid additional stresses on the three-way control valve, such as the pipe is not concentric with the valve or the flange is not parallel.

3) The working environment temperature of the three-way control valve should be (-30 + 60), and the relative humidity should not be more than 95%. Because the membrane and sealing ring of the control valve and other rubber parts are easy to harden and become brittle at low temperatures, and aging at high temperatures, it is necessary to pay attention to the installation position during installation and leave the heating furnace and high temperature pipeline.

4) There should be a straight pipe section at the front and rear positions of the three-way control valve, and the length of the straight pipe section before and after the valve should not be less than 10 times the pipe diameter (10d), so as to avoid the straight pipe section of the valve being too short and affecting the flow characteristics.

5) When the caliber of the three-way control valve is different from the process pipeline, it should be connected by reducer. In the installation of small-bore control valves, threaded connections are available. The fluid direction arrow on the valve body should be consistent with the fluid direction.

6) The three-way control valve should be completely removed from the foreign matter in the pipeline before installation, such as dirt, welding slag, etc. After installation, test run with room temperature water, and the valve should be fully opened or the bypass valve should be opened during the test run. During the trial operation, attention should be paid to the tightness of the connection between the valve body and the pipeline.

3. Installation formThe installation of the three-way control valve usually has a control valve group, namely the upstream valve, the bypass valve, the downstream valve and the control valve.

4. The selection of the installation orientation of the three-way control valve usually requires the control valve to be installed vertically. When the vertical installation cannot be satisfied, the control valve fixed with 4 bolts to the flange can be tilted up 45°, tilted down 45°, horizontally installed and vertically installed downward. The control valve with 8 bolts to the flange can be installed in 9 positions, separated by °.

Among these installation positions, the most desirable is vertical upward installation, which should be preferred; The upward slope is second, followed by °; Downward vertical installation for the re-position; The worst position is the horizontal installation, which is inclined downward with a close horizontal installation, and generally does not be.

5. The maintenance of the three-way control valve is due to the vicious environment of the control valve, and it is inevitable that there will be certain failures in use. Therefore, it is necessary to carry out certain maintenance and repair of the control valve.

As long as he has a tee connected to the tube, it's fine.
