The multifunctional water pump control valve is a new type of hydraulic control valve, which can replace the three devices of electric butterfly (gate) valve, check valve and water hammer eliminator. So everyone knows what are the working principles and advantages of the multifunctional water pump control valve?
The working principle of the multifunctional water pump control valve:
1. Before the water pump is started, the pressure at the outlet end of the valve acts on the main valve plate, and the valve is in the closed position. At the same time, the upper cavity of the diaphragm controller is connected with pressure water, and the lower cavity is connected to the inlet end of the valve. Low pressure 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, and the opening speed can be adjusted by the control valve.　　
3. The water pump stops and the pressure at the valve inlet drops. When the flow is close to zero, the main valve plate closes quickly under the action of its own gravity.
The main advantages of the multifunctional water pump control valve: 　　
1, no need for operation control. The water pressure difference before and after the valve is used as the control power when the water pump starts and stops, and it has the function of automatically opening and closing with the opening and closing of the water pump.　　
2. The valve opening and closing action process can effectively prevent accidents caused by the increase of water hammer pressure wave. According to the on-site usage investigation and actual measurement, the peak value of the water hammer pressure when the pump is stopped is within 1.3 times of the working pressure.　　
3. No on-site debugging is required, and it is applicable to a wide range of working conditions.　　 4. Basically no maintenance is required. Because one valve replaces three valves, the maintenance workload is greatly reduced.　　
5. The resistance loss is small. With streamlined and wide valve body design, the resistance loss is reduced by more than 50% compared with similar foreign products. The working principle and advantages of the multifunctional water pump control valve are mainly those introduced above. We should all have a correct understanding and understanding of the working principle and advantages of our multifunctional water pump control valve, and the correct way to operate and use our valve
