水厂水泵止回阀的选型与应用

Selection and Application of Check Valve for Water Pump in Water Treatment Plant

对水厂在用的不同止回阀进行了水头损失测试,结果表明,止回阀流道设计合理、活动部件少则水头损失小。此外,止回阀的结构、使用场合及操作控制工作方式也是其选型的重要考虑因素。

The head loss of different check valves used in water plant were determined. The resuhs show that rational design of check valve flow channel as well as fewer function component of check valve could reduce head loss. Furthermore, the structures, us- ing sites and operation methods of check valve are also the important factors for selection.
