The multifunctional water pump control valve can automatically realize the slow opening when the pump is turned on, the quick closing and slow closing when the pump is stopped, without any electrical control, other power and manpower, and no hydraulic device. So everyone knows how the multifunctional water pump control valve works?
The working principle of the multifunctional water pump control valve is as follows:
1. 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. As the pressure at the inlet of the valve decreases, the pressure water at the outlet of the valve enters the upper cavity of the diaphragm controller through the connecting pipe.
2. After the water pump is started, the valve inlet pressure gradually rises, and the pressure water slowly enters the lower cavity of the diaphragm controller through the connecting pipe at the valve inlet end to realize the slow opening of the main valve plate, and the opening speed can be adjusted by the control valve.
3. Before the water pump starts, 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 communicates with pressure water, and the lower cavity communicates with the low pressure at the inlet of the valve. The opening and closing action process of the multifunctional water pump control valve can effectively prevent accidents caused by the rise of water hammer pressure waves. 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.
When we all operate and use the multifunctional water pump control valve, we should all operate according to its principles.
