摘　　要：凝结水加药泵出口安全阀是系统超压的最后一道保护,在任何情况下都应该保证其功能。但机组运行中凝结水加药泵出口安全阀出现频繁泄漏等故障,通过对故障现象进行原理分析,最终找到故障原因并进行了技术改进。Outlet valve of condensate dosing pump is the last system overpressure protection,which should en-sure its functionality in any case. However the valve leakage fault of condensate dosing pump occurs frequent-ly in the running unit. We find the cause of the malfunction finally,by analyzing the principle of the fault phe-nomena.
