The multifunctional water pump control valve is used on the pump outlet pipes of the water supply system of high-rise buildings and other water supply systems to prevent and reduce water hammer and water hammer of the pipeline when the pump is opened and closed, prevent water backflow, protect the pump, and maintain the safety of the pipeline. So what are the characteristics and working principles of the multifunctional water pump control valve?
1. Working characteristics of JD745X multifunctional water pump control valve: 1. The valve body adopts a full-channel, direct-flow and streamlined design. The hydraulic loss is small and the energy saving effect is good.
2. Easy to operate, no need to add a power distribution control system for the valve, the valve will automatically complete the control function in sequence with the opening and stopping of the water pump. Appropriate control parameters can be obtained by setting the opening of the regulating valve.
3. The effect of preventing water hammer is good, integrating the technology of eliminating water hammer such as slow opening, non-return quick closing, slow closing, etc., to prevent the damage to the water supply pipeline and the water pump due to the failure of the pump, the backflow and the water hammer.
4. Working principle of JD745X multifunctional water pump control valve: When the water pump starts, the water pressure acts on the bottom of the main valve disc and the lower cavity of the control room. This pressure makes the main valve open, and the water in the upper cavity of the control room is slowed down by the regulating valve B. Slowly discharge to the outlet end, and the main valve opens slowly. Setting the opening degree of the regulating valve can get a proper opening speed of the main valve.
When we all operate the JD745X multifunctional water pump control valve, we should all operate and use it according to its working principle. We also pay more attention to understanding its principle and characteristics.
