Diaphragm multifunctional water pump control valve is an intelligent valve installed at the pump outlet of water supply system and other water supply systems on high-rise buildings to prevent medium backflow, water hammer and water hammer.
The working principle of the multifunctional water pump control valve is as follows:
  When the multi-function water pump control valve water pump starts, the water pressure acts on the main valve disc and the lower cavity of the control room. This pressure opens the main valve. The water in the upper cavity of the control room is slowly discharged to the outlet through the regulating valve B. The main valve opens slowly. Setting the opening degree of the regulating valve can get a proper opening speed of the main valve. When the water pump stops working, the water pressure at the inlet drops rapidly, and most of the opening is quickly closed under the action of its own weight and spring pressure to prevent water backflow. The remaining opening is combined by the water pressure in the upper cavity of the control chamber and the water pressure in the lower cavity. Slowly closing down, the slowing down of the closing speed forms a buffer to prevent the pressure from increasing sharply. Setting the opening and opening ratio of the regulating valve A and B can obtain the appropriate opening and closing speed of the valve.
  The diaphragm type multifunctional water pump control valve has three functions of electric valve, check valve and water hammer eliminator, which can effectively protect the safety and reliability of the water supply system, and integrate the technical principles of slow opening and slow closing to eliminate water hammer. To prevent the water hammer when the pump is turned on and when the pump is stopped.
