针对引水管道内压力波动诱发强烈振动问题,研究了水电站或泵站蝶阀开启状态时所承受的水流时均和脉动荷载特征,计算了水力诱发阀门的振动响应,分析了阀门销轴等构件的疲劳效应和阀门突然关闭对管道阀门门体的影响.研究成果可为工程设计和安全运行提供依据.
In view of the problem of strong vibration induced by the pressure fluctuation in the diversion pipe, the characteristics of mean and fluctuating load of water flow when the butterfly valve is opened are studied. The vibration response of the hydraulically induced valve is calculated. The fatigue of the valve pin and other components is analyzed Effect and sudden closure of the valve on the pipeline valve door.The research results can provide basis for engineering design and safe operation.
