安全阀在线检测技术
Application and character 适用范围及特点
All test process does not touch the work of media in safety valve, so the use of instrument is independent of the media types,internal pressure and ，因此，理论上讲该仪器的使用与检测安全阀的工作介质种类(气体，液体）及介质压力、温度无关。
For the medium of granular, easy-coke safety valve, should not use online 、易结焦的安全阀，不宜使用在线检测。
For full-size models of spring-loaded safety valve

It do not stop the plant and measure the valve set pressure, back pressure, open height, without the need to improve the system 、回座压力、开启高度，而不需要提高系统压力
If the safety valve leakage the instrument can be forced to close the disc and , without affecting the value of set pressure.
回座后有泄漏时可用强关系统将阀瓣强行关闭,而不影响定压值
