止回阀泄漏故障模式分析及处理

Analysis and Treatment of Leakage Failure Mode of Check Valve

核电站中使用了许多止回阀,特别是在供水、供气回路以及安全壳贯穿管道上。论文主要介绍了核电站最常见的升降式和旋启式止回阀的原理、结构以及最常见的泄漏故障的分析以及实际处理的方法。

There are many check valves used in the nuclear power plant,especially the water and gas supply pipes and the containment pipes.This paper mainly introduces the principle and structure of the most common lifting and swing check valves in nuclear power plants,as well as the analysis of themost common leakage faults and the actual treatmentmethods.
