摘要
引入了阀门“几何开度”和“水力开度”的概念，在此基础上讨论了不同阀门的过流特性。结合实例，分析了在三机式抽水蓄能电站水轮机丢弃负荷和水泵断电这两种事故工况下，不同阀门的过流特性对水击过程的影响。
Introduce the concept about valve “geometry opening” and “hydraulic opening”,on this base,discuss the overflowing property of various valves.Use example,analyse the influence of various valve overflowing property in the process of water shock,under turbine losing load and water pump outage two kinds accident working condition of three sets type pumped storage power station.
