Structure characteristics of JD745X multi-function water pump control valve
 

由主阀和调节阀及接管系统组成,阀体采用直流式阀体,主阀控制室为膜片式或活塞式的双控制室结构,控制室比一般水力控制阀增加了一个, JD745X multi-function water pump control valve is composed of main valve, regulating valve and takeover system. The valve body adopts DC valve body. The main valve control room is a diaphragm or piston type double control room structure. The control room is larger than the general hydraulic control valve. Got one,
The control function of the main valve is added to realize the multi-function control of slow opening, full opening, slow closing, and closing of the pump outlet, and the multi-function control of the pump outlet with one valve and one-time adjustment. Takeover system for this product
It adopts control valve control. By setting the opening degree of the control valve, various control parameters such as the opening speed and slow closing speed of the main valve can be easily realized.


Working principle of JD745X multifunctional water pump control valve
 

When the pump is started, water pressure acts under the main valve disc and in the lower chamber of the control room. This pressure causes the main valve to open. The water in the upper chamber of the control room is slowly discharged to the outlet through the regulating valve B. The main valve opens slowly. .
Setting the opening degree of the regulating valve can obtain the proper opening speed of the main valve. When the pump stops working, the water pressure at the inlet quickly drops, and most of the openings are quickly closed under the action of the weight and spring pressure, preventing the remaining openings from flowing backward.
The water pressure in the upper chamber of the control chamber and the water pressure in the lower chamber are slowly closed under the combined effect of slowing the closing speed to form a buffer to prevent a sudden increase in pressure. Setting the opening degree and opening ratio of the regulating valves A and B can obtain an appropriate valve opening and closing speed.


Working characteristics of JD745X multi-function water pump control valve
 

1. The effect of preventing water hammer is good. Integrate the technology of eliminating water hammer, such as slow opening, non-return speed closing, slow closing, etc., to prevent the water from being damaged when the pump is not turned on and the pump stops flowing backward and the water hammer.
F745X隔膜式遥控浮球阀 操作方便,无需为阀门另配电控系统,阀门随水泵的开启与停止自动并按顺序完成控制功能。 2. F745X diaphragm type remote control floating ball valve is easy to operate, no need to control the power distribution system for the valve, the valve automatically and sequentially completes the control function with the opening and stopping of the pump. Appropriate control parameters can be obtained by setting the opening of the regulating valve.
3. The valve body adopts a full channel, DC type and streamlined design. Small hydraulic loss and good energy saving effect.


Functions and uses of JD745X multifunctional water pump control valve
 

The valve is installed at the outlet end of the pump, and realizes the functions of slow opening, full opening, quick closing, and slow closing in sequence.
This product is used in the water pump outlet pipes of high-rise building water supply systems and other water supply systems to prevent and reduce the water hammer of the pipeline when the pumps are opened and closed, to prevent water backflow, to protect the pumps, and to maintain pipeline safety.
