Abstract：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.
