a, JD745X multifunctional water pump control Industrial Valves summary:

JD745X multifunctional water pump control valve is installed in the high-rise building water supply system and other water supply system of the pump outlet, prevent the backflow medium, water hammer and the intelligent valve water hammer phenomenon. The valve with electric Industrial Valves, check valve and water hammer eliminator three functions, which can effectively improve the safety and reliability of water supply system. And will be slow to open, quick closing, slowly-closing eliminate water hammer principle of technology integration, to prevent drive pump water hammer and stop the pump water hammer. Only need to open/close button operating the pump motor, the valve can be according to the water pump operating rules automatically opening and closing, large flow, small pressure loss.

2, JD745X multifunctional water pump control valve structure features:

this product is composed of the main valve and regulating valve and take over the system, the valve body adopts once-through body, the main valve control room for the diaphragm or piston type double control room design, hydraulic control valve added a control room, strengthen the function of the control of the main valve, achieved to pump export slowly open, open, closed, as of multi-function control, implement a valve, a multifunctional control of pump export adjustment. This product to take over the control system adopts the regulator, by setting valve opening, can be convenient to realize the need of various control parameters, such as the main valve opening speed, hydraulic slowly-closing speed and so on.

three, JD745X multifunctional water pump control valve working principle:

when the water pump after starting up, water pressure acting on the main valve under the valve plate and the control room inferior vena, this pressure makes the main valve opens, the control room on the cavity of the water after the regulator B slowly into the outlet, the main Industrial Valves opened slowly. Set the valve opening right landlord valve open speed can be obtained. When the pump stop working, the inlet pressure drop quickly, in under the action of dead weight, spring pressure fast shut down most of separating degree, prevent the water back in the rest of the opening from the control room on the cavity pressure and inferior vena under water pressure is slowly closing, closed at a slower pace formed the buffer, to prevent the pressure surge. Set the opening of the valve A and B and opening than suitable valve opening and closing speed can be obtained.
