JD745X Multifunctional pump control valve

when the pump is opened , the inlet pressure acts under the sliding disc ,and th e inet pressure also enters the diaphragm through the small ball valve and the small filter on the inlet side , So that the valve is sowy opened to prevent the opening of the pump water hammer.

working principle:

when the pump is opened , the inlet pressure acts under the sliding disc ,and th e inet pressure also enters the diaphragm through the small ball valve and the small filter on the inlet side , So that the valve is sowy opened to prevent the opening of the pump water hammer. when the pump is stopped , the sliding disc under the action of its own weight and spring , first quickly shut down 90% to prevent water backf owand prevent the production of water hammer, and the remaining 10% is entered into the upper part of the diaphragm by the medium at the outlet end through the small ball valve and the small filter, and the closing speed slows down to produce a buffering process to prevent the pressure accumulation and achieve silent closure.

Product characteristics
1.The elimination of water hammer effect is good. The technical principles of slow opening, fast closing and slow closing to eliminate water hammer are integrated to prevent the production of water hammer for opening pump and water hammer for stopping pump.
2.Easy to operate. Only need to operate the pump motor opening and closing button, the valve is automatically opened and closed according to the pump operating procedures
3.Good energy saving effect. The valve body adopts the streamlined straight flow design, the pressure loss is small, the flow is large, and the volume is small, the weight is light.
4.The valve adopts a double-chamber transmission mechanism,which is divided into two different pressure chambers, which is characterized by smooth water closure without pressure fluctuations. In addition, the entire transmission mechanism can be disassembled as a whole, without removing the diaphragm, so as to facilitate inspection.

Argument
1.Working pressure:1.0Mpa, 1.6Mpa, 2.5Mpa
2.Applicable Medium:water
3.Applicable Temperature:0~80℃
