摘　　要：简要介绍某三废处理设施的阀门类型和故障特点。检修分析认为，阀门故障多数由于机械连接处的蠕变、介质中存在破坏性杂质造成，故障周期为1—2a。文章给出了检修方法、检修周期和检修流程的建议。The valve type and valve failure characteristics of radioactive waste treatment facilities are introduced in this paper. The result shows that most of the valve failure is resulted from the creep of mechanical joint and the destructive impurity in the medium. The cycle time for valve failure is 1 to 2 years. The suggestion for maintenance method, maintenance cycle time and maintenance procedure are pointed out.
