摘　　要：高压锅炉给水泵现配套使用的自动循环阀为第一代机械式自动循环阀,这种结构的自动循环阀在使用时一直存在回流泄漏的技术问题,严重影响装置安全生产及稳定运行。通过对阀门的结构型式进行技术换代,解决了高压锅炉给水泵出口自动循环阀内漏问题。The automatic circulation valve used in high pressure feed water boiler is the first generation mechanical type valve.During its application,there always existed the backflow leakage problem,which seriously influenced the safety and stable operation.Updating the valve structure to the new generation,the inner leakage at the outlet of the valve was solved.
