Abstract: Many solenoid valves were imported from France for Daya Bay and Ling'Ao nuclear power plants. Some phenomena of leaking air or oil and rustiness occurred in solenoid valves with the serve time increases.All malfunction phenomena were classified, operation principle of the solenoid valve was analyzed in combination with relevant information, and the failure mode was summarized. The maintenance strategy of the solenoid valve for Daya Bay and Ling'Ao nuclear power plants was put forward, with reference to the maintenance methods of EDF. It could be served as reference for solenoid valve maintenance in nuclear power plants of similar kind.
Key words: solenoid valve; operation principle; failure mode; maintenance strategy
大亚湾与岭澳核电站系统设备上使用了很多进口电磁阀，目前国内还没有合适的替代品。随着服役时间的延长，这些电磁阀出现了不少的问题。本文对电磁阀的故障现象、工作原理、失效模式及机理进行全面分析，提出了电磁阀的维修策略。
