Before actual operation, close the lower valve, and then open the black cover above the pressure reducing valve.
1. If you want to increase the pressure, turn the valve clockwise.
2. To reduce the pressure at the outlet, rotate the valve counterclockwise, then adjust the pressure value of the valve, and finally open the valve below.
What should I pay attention to when using pressure reducing valve?
In order to ensure that the pressure reducing valve can play an appropriate role in the water supply system, the corresponding rules and regulations should be followed in actual use. The following are some precautions when using.
1. Before use, check whether the pressure reducing valve is set in front of the entrance of the alarm valve group. If the pressure reducing valve is equipped with more than two alarm valve groups, it should be equipped with a spare pressure reducing valve. In addition, pay attention to whether there is a pressure test drain valve behind the pressure reducing valve to ensure its normal work.
2. When in use, if there are impurities in the water, the valve core and needle of the pressure reducing valve are easily blocked, which leads to the failure of the pressure reducing valve. In order to avoid this situation, it is necessary to equip the pressure reducing valve with a high-quality filtering device, which can remove impurities in water.
3. The pressure reducing valve is a kind of energy dissipator, so it consumes a lot of energy. In order to ensure sufficient water supply in case of fire, the outlet pressure of hydraulic valve has corresponding regulations, and it is necessary to ensure that the outlet dynamic pressure cannot be lower than 650% of the set negative value.
The above is the specific method to adjust the pressure by using the pressure reducing valve. Pressure reducing valve plays a very important role in water supply system. In order to ensure its normal operation, it must be checked regularly to ensure its smooth operation, and appropriate adjustment methods must be adopted. I hope I can help you.
