在安全阀离线校验时对阀瓣位移量进行测定,对安全阀开启的判定将更加精准,避免将泄漏误判为开启.该文通过在安全阀开启压力数字化检测系统中加装激光位移传感器、位移靶标等,对安全阀离线校验过程中的阀瓣位移量测量进行了研究,得到了安全阀校验中阀瓣位移量的测量方法与适用范围.实验结果表明,可以通过检测阀瓣位移的方式,区分全启式安全阀的泄漏与开启.研究结果为准确判定安全阀开启提供了技术支撑.
Research on Valve Disc Displacement Detection in Off-line Safety Valve Calibration
The determination of the valve disc displacement during offline calibration of safety valves enhances the precision of identifying valve opening,preventing the misinterpretation of leaks as openings.Through the integration of a laser displacement sensor and displacement targets into the digital pressure detection system for safety valve open-ing,an investigation was conducted into the measurement of valve disc displacement during safety valve offline cali-bration.The study yielded a method and applicable range for measuring valve disc displacement in safety valve cali-bration.Experimental results demonstrate that distinguishing between leaks and openings in full-lift safety valves can be achieved by monitoring the valve disc displacement.The findings provide technical support for accurately deter-mining safety valve openings.
