The multifunctional water pump control valve is installed on the pump outlet pipe of the water supply system of high-rise buildings and other water supply systems to prevent water hammer and water hammer. So what do you know about the structure and principle of the multifunctional water pump control valve?　　 1. The structure of the multifunctional water pump control valve:
The multifunctional water pump control valve structure consists of the main valve and external accessories. The main valve includes a valve body, a main valve plate, a slow closing valve plate, a valve stem, a valve seat and a diaphragm controller. 2. The working principle of the multifunctional water pump control valve: 　　 1) Before the water pump starts, the pressure at the outlet end of the valve acts on the main valve plate, the valve is in the closed position, the upper cavity of the diaphragm controller is connected to pressure water, and the lower cavity is connected with the valve The low pressure at the inlet side is connected.　　2) After the water pump is started, the valve inlet pressure gradually rises, and the pressure water slowly enters the lower chamber of the diaphragm controller through the connecting pipe at the inlet end of the valve to realize the slow opening of the main valve plate. The opening speed can be adjusted by the control valve.
3) The water pump stops and the pressure at the valve inlet decreases. When the flow is close to zero, the main valve plate closes quickly under the action of its own gravity.
The multifunctional water pump control valve is installed on the pump outlet pipe of the water supply system of high-rise buildings and other water supply systems. Prevent the occurrence of water hammer and water hammer. The valve has three functions: electric valve, check valve and water hammer eliminator. Can effectively improve the safety and reliability of the water supply system.
When we all operate the multifunctional water pump control valve, we all need to understand the structure principle of our valve, and the correct way to operate and use our valve is what we need.
