JD745X型多功能水泵控制閥是安裝在大口徑給水管網系統的水泵出口處、防止介質倒流、水錘及水擊現象的智能型閥門。
JD745X type multi-functional pump control valves is installed in large diameter of the water pump outlet pipe network system, and to prevent the backflow medium, water hammer and water attack of intelligent valve phenomenon.

Second, multi-function pump control valves function and purpose

Multifunctional pump control valve installed in water pump outlet, order, open, slowly open realize speed closed, slowly-closing etc. Function. Multifunctional pump control valves used in high-rise buildings water system and other water supply system of water pump export pipelines, prevent and abate when opening and closing of the pipeline pump water hammer water attack, prevent water flow back to protect water pump, maintain the safety line.
