高水头水电站主阀的选型

Selection of Main Valve in High Water Level Hydroelectric Power Stations

针对高水头、小容量的水电站,走访了主要阀门设备生产厂,对国内的几种水轮机进水主阀进行了选型比较,参照同类型用户的反馈信息,结合桐柏电站的改造经验,证明液压球阀投运能达到设计要求,投运后设备运行状态良好。

The paper compares several domestic main valves for hydroelectric power stations with high water level and limited capacity, in combination with the experience from the technology innovation of Tongbai Hydroelectric Power Station, we come to a conclusion that hydraulic pressure ball valve is able to meet demands of design with good performance.
