多功能水泵控制阀在水厂的应用

为了解决水厂设计中水泵常见的水锤问题，克服传统的手动闸阀和止回阀诸多不利的缺点，减少故障几率，提高水厂的安全生产可靠性，在沾化水厂二级泵房管道上安装了JD745X型多功能水泵控制阀替换止回阀，原手动控制阀保留并作为检修阀使用。经过多年运行及数据分析，认为此水泵控制阀是一种兼水泵控制、止回、消除水锤三种功能于一体的控制阀门，在解决各种故障问题上，具有良好的运行效果，是水泵压水管阀门的更新换代产品，值得推广应用，具有较广的应用前景。

The Application of Multi-function Control Valve in Pumping System of ZhanHua Water Works

In waterworks design, in order to solve the problem of water hammer, overcome a great deal of unfavourable shortcomings of the trodiational manual gate valve and check valve, and reduce trouble probability, we installate multi-functional control valve of JD745X for pump to replace check valve on second pump house pipeline at ZhanHua water works, manul gate valve is kept and used as overhal valve; The new multi-function control valve for pumping system has been operated and data analyzed for many years, it has good result in resolving water hammer etc. It is the product that can renew the old one on water pump discharge system.
