How to Adjust the Tap Water Pressure Reducing Valve? What Is the Installation Method of Tap Water Pr

Tap water is important for our home life. People's life is inseparable from water resources. Generally, when installing tap water, a pressure reducing valve or booster valve will be installed. Both are small tools, but they play an important role in the use of tap water. Today, let's see how to adjust the tap water pressure reducing valve? What is the installation method of tap water pressure reducing valve?

How to adjust the tap water pressure reducing valve?

1. The basic performance of the water pipe pressure reducing valve is: the pressure regulating range is mainly related to the stiffness of the pressure regulating spring. The pressure regulating range is within the specified range of the output pressure P2 of the water pipe pressure reducing valve, and it must be ensured to reach the specified accuracy. When the flow G is constant, the fluctuation of input pressure will cause the fluctuation of output pressure. The smaller the output pressure fluctuation, the better the characteristics of the pressure reducing valve. Therefore, the output pressure must be lower than the input pressure - fixed value in order to keep the pressure range from changing with the input pressure. In the input pressure - timing, the output pressure will change with the change of output flow G.

2. Close the on-off valve in front of the pressure reducing valve and open the on-off valve behind the pressure reducing valve to create the downstream low-pressure environment; Turn the adjusting screw counterclockwise to the upper position (relatively low outlet pressure), and then close the rear on-off valve of the pressure reducing valve;

3. Slowly open the on-off valve in front of the pressure reducing valve to fully open; Slowly rotate the adjusting screw clockwise to adjust the outlet pressure to the required pressure (subject to the gauge pressure behind the valve); After adjustment, lock the lock nut and open the gate valve behind the pressure reducing valve; Note: it can only be adjusted from low pressure to high pressure

What is the installation method of tap water pressure reducing valve?

1. If the pressure reducing valve in tap water does not have its own pressure gauge, a pressure gauge should be installed on the pipeline before and after the valve.

2. If the medium contains impurities, the valve hole may be blocked. Install a pipe filter about 1m before the inlet of the tap water pressure reducing valve, and the mesh of the filter should be well controlled above 20 mesh.

3. In order not to affect the use effect of pressure reducing valve, and considering the convenience of installation and maintenance, the tap water pressure reducing valve is generally installed on the horizontal pipeline, and the bellows pressure reducing valve is upside down.

4. Before installing the tap water pressure reducing valve, check whether the nameplate and certificate are consistent with the required valve model and working conditions, and whether the appearance is seriously damaged. Fully flush the pipeline and flush the pressure reducing valve. If the pressure reducing valve of Shenzhen Euro valve is stored for a long time, it is necessary to fully clean the inside of the pressure reducing valve body.

5. In order to prevent accidents caused by overpressure behind the valve, a safety relief valve should be installed at about 4m from the outlet end of the tap water pressure reducing valve, just in case.

6. Pay attention to the direction of the arrow on the valve body before installation. The arrow points to the direction of medium flow and cannot be installed reversely, otherwise the pressure reducing valve will fail and cause accidents! I hope I can help you.

After the introduction of the above article, how do you adjust the tap water pressure reducing valve? What is the installation method of tap water pressure reducing valve? I think I know almost. Tap water pressure reducing valve is mainly used to alleviate the impulse of tap water and plays a very important role in use, so installation is very important. We must pay attention to safety issues during installation. In addition, we must install in combination with the actual situation and put safety issues first.
