1压力容器安全阀密封性能的重要性安全阀作为压力容器、压力管道的安全附件对设备系统的安全运行有非常重要的作用,安全阀的密封性能是安全阀性能的重要指标。安全阀除超压时必须开启泄压外,其他工作时间应能可靠地达到密封要求,不得出现泄漏现象。在正常工作状态下,安全阀的密封性不好是安全阀结构的一个很严重的缺陷。安全阀泄漏一方面造成工作介质损耗,另
1 pressure vessel safety valve sealing the importance of safety valve as a pressure vessel, pressure pipe safety accessories on the safe operation of the equipment system is very important role in the safety valve sealing performance is an important indicator of safety valve performance. Safety valve in addition to overpressure must open the pressure relief, the other working hours should be able to reliably meet the sealing requirements, shall not leak. Under normal working conditions, the poor sealing of the safety valve is a very serious defect of the safety valve structure. Safety valve leakage on the one hand caused by the loss of working medium, and the other
