火力发电厂高压阀门泄漏原因及处理方法

A Study on the Causes of the Leakage of High Pressure Valves in a Thermal Power Plant and Relevant Solutions

以四川泸州川南发电有限责任公司为例,简述火力发电厂高压阀门在设备运行中泄漏的部位及原因。同时,介绍在设备运行中处理阀门泄漏点使其不漏或减小泄漏量的方法,减少机组非计划停机次数,以保证机组运行的稳定。

Taking Sichuan Luzhou Chuannan Power Generation Co. ,Ltd. for example,this paper sketches the leak-age locations of high pressure valves in a thermal power plant during the operation of the equipment as well as possi-ble causes. In addition,it introduces relevant ways of stopping the leakage points and reducing the amount of leak- age,to decrease the times of unplanned halts of the unit as well as ensuring its stable operation.
