双节拍门水头损失系数模型试验研究

MODEL TEST AND RESEARCH ON THE COEFFICIENT OFWATERHEAD LOSS OF TWO-STAGE FLAP VALVES

进行了双节拍门水头损失系数模型试验，对试验结果进行了分析与讨论，给出了双节拍门水头损失系数和经验公式，为泵站和拍门设计及计算提供了技术参数。

A model test is conducted on the coefficient of waterhead loss of two-stage flap valves,andthe test results are analysed and discussed.On the basis of the model test,an experimental formula of calcu-lating the coefficient of waterhead loss of two-stage flap valves is derived for the design of two-stage flapvalves and pumping stations.
