先进压水堆核电站电磁动截止阀端部加载鉴定试验研究

Research on End-loading Test for Solenoid Globe Valve of Advanced PWR

摘要: 针对核电设备鉴定试验中的阀门端部加载试验，以先进压水堆核电站堆顶排气阀使用的电磁动截止阀为例，基于ASME QME-1标准要求，对阀门端部加载试验的方法和载荷计算进行了探讨。介绍了电磁动截止阀端部加载试验装置、试验过程和结果，由测得的应变测量曲线和端部加载试验后的阀门功能试验证明该阀门样机通过了阀门端部加载试验。通过系统性介绍阀门端部加载试验的方法和技术要点，对行业内开展相关设备鉴定具有重要借鉴意义。

Abstract: On account of valve end-loading test belonging to nuclear equipment qualification test, solenoid globe valve applied as RPV head exhaust valve for advanced PWR was taken as an example, method of valve end-loading test and loading calculation were discussed based on ASME QME-1. Test devices, procedure and results of solenoid globe valve end-loading test were introduced, the measured strain curves and functional test after end-loading test proved that the valve specimen was qualified for the end-loading test. The systematic introduction of method and technical essentials of valve end-loading test can be a significant reference for equipment qualification in the industry.
