电动主汽门疏水阀门改造

Improvement of drain valve of electricity-driven main stop valve

针对云浮发电厂2号机电动主汽疏水门,在机组运行及事故处理过程中易出现填料被蒸汽严重冲刷及疏水门频繁内漏现象,影响机组的安全运行。改造后,2号机电动主汽疏水门没有发生泄漏,提高了设备运行的安全性。

Forcing on frequent leakage of drain valve of No. 2 turbine electricity operation in Yunfu Power Plant, the drain valve was improved technologically the drain valve has never leaked after modified, which enhances its safety. - driven main stop valve during based on analyzing its reasons,
