双节拍门水头损失系数模型试验研究

Model study on the head loss coefficient of two-stage flap valves

本文进行了双节拍门水头损失系数模型试验研究，对试验结果进行了分析与讨论．在模型试验的基础上，给出了双节拍门水头损失系数经验公式，为泵站和拍门设计提供了技术参数．

Model tests are conduct6d to investigate the coefficient of head loss of twostage flap valVes. On the basis of model test, an empirical formula for the coefficient of head loss for two-stage flap valves is derived and technical data are provided for the design and computation of this kind of flap valves.
