Diaphragm multifunctional water pump control valve

JD745X multifunctional water pump control valve is an intelligent valve installed at the water pump outlet of a large-diameter water supply pipe network system to prevent medium backflow and water hammer. This valve has three functions: electric valve, check valve and water hammer eliminator, which can effectively improve the safety and reliability of the water supply system in which fire water and domestic water are connected in parallel in the residential area. The double-chamber structure can use the valve to quickly close 90% after the system is stopped (to prevent the backflow of the medium from causing the water pump to reverse), and to slowly close the remaining 10% (to eliminate destructive water hammer). The piston valve has reliable performance, high strength and action It is stable and suitable for water hammer when the pump is started and when the pump is stopped. Just operate the opening and closing button of the water pump motor, and the valve can automatically open and close according to the water pump operating procedures. The process is large and the pressure loss is small.

The multifunctional water pump control valve is a new type of hydraulic control valve. One valve can replace three devices: electric butterfly valve, check valve and water hammer. It can automatically realize slow closing of the pump, quick closing and slow closing when the pump is stopped, without any electrical control, other power and manpower, and no hydraulic device. The main advantages of the multi-function water pump control valve are: no operation control is required. The water pressure difference between the front and rear of the valve when the water pump starts and stops is used as the control power, and it has the function of automatically opening and closing with the opening and closing of the water pump.
