How to adjust the outlet pressure of pressure reducing valve?
Pressure reducing valve is through the adjustment, to achieve the inlet pressure reduced to a required outlet pressure, and rely on the medium itself to make the outlet pressure automatically maintain a stable valve. In regulating the pressure reducing valve pressure, should be based on the actual needs of the system and working conditions to choose the appropriate adjustment method and parameters, and follow the relevant safety regulations.
Overview
Procedure：
1. Find the place to adjust the outlet pressure of the pressure reducing valve, loosen the lock nut on the regulating screw, and use a wrench to screw the pressure reducing valve regulating screw counterclockwise to the loosest state;
2. Remove the plug of the pressure gauge interface on the pressure reducing valve and install the pressure gauge to the pressure gauge interface;
3. Install the pressure reducing valve to the pipeline, close the stainless steel pressure reducing valve valve after the ball valve or gate valve;
4. Use a wrench to rotate the regulating screw clockwise, so that the spring force gradually becomes larger, you can find that the pressure gauge readings continue to become larger, when the desired outlet pressure value, stop rotating, tighten the regulating screw lock nut;
5. Open the ball valve or gate valve after the pressure reducing valve, open the valve faucet or other water appliances, observe the pressure reducing valve valve body on the pressure gauge readings, you can find that the pressure value than just set the pressure value is slightly smaller, this is normal, because the adjustment of pressure is carried out in the state of static pressure, when someone is using water, water from the spool through the valve there will be a certain degree of resistance to the liquid, so the pressure will be slightly smaller, when no one When no one uses water, the pressure value will return to the set value.
6. If you need to reduce the outlet pressure of the pressure reducing valve installed on the system, first close the ball valve or gate valve at the inlet of the pressure reducing valve, open the ball valve or gate valve at the outlet of the pressure reducing valve, drain the pressure off from the outlet of the pressure reducing valve, then adjust the pressure regulating spring to the loosest, close the ball valve or gate valve at the outlet of the pressure reducing valve, open the ball valve or gate valve at the inlet of the pressure reducing valve, and then slowly increase the outlet pressure of the pressure reducing valve to the required value by rotating the valve clockwise again. pressure to the desired value.
