摘要
阀门作为流体传输系统中的控制部件,在核电厂中被大量使用。核级阀门紧急切断和打开流体通道的能力对于保障核电站工艺系统的安全稳定运行具有极其重要的意义。通过分析气动阀门进行大口径电磁阀改造可行性及改造效果,并对电磁阀背板更换及仪控部件物项替代后背板强度、固定螺栓应力以及重量变化对阀门整体抗震性能的影响进行了评估,为核电厂解决气动阀门开、关时间无法满足需求的问题提供参考。
Valves are widely used in nuclear power plants as control components in fluid transmission systems.The ability of nuclear grade valve to cut off and open the fluid channel is very important to ensure the safe and stable operation of nuclear power plant process system.This paper analyzes the feasibility and effect of reforming large diameter solenoid valve with pneumatic valve,also evaluates the effects of back panel strength,fixed bolt stress and weight change on the overall seismic performance of the valve after the replacement of solenoid valve back panel and instrument and control components,which provides reference for solving the problem that the opening and closing time of pneumatic valve cannot meet the demand in nuclear power plant.
