The piston type multifunctional water pump control valve is an intelligent valve installed at the outlet of the water pump of the large-caliber water supply pipe network system to prevent medium backflow, water hammer and water hammer. The valve combines three functions of electric valve, check valve and water hammer eliminator, which can effectively improve the safety and reliability of the water supply system. The dual-chamber and dual-valve structure can quickly close 90% of the valve after stopping the pump (to prevent the return of the medium from causing the pump to reverse), and then slowly close the remaining 10% (eliminate destructive water hammer). The piston valve has reliable performance and high strength , The action is stable to prevent water hammer when the pump is turned on and when the pump is stopped. Only by operating the opening and closing button of the water pump motor, the valve can be opened and closed automatically in accordance with the pump operation regulations, with large flow and small pressure loss.
