针对传统的安全阀密封试验人工数气泡法繁琐、低效，准确性和可靠性差等问题，将计算机组态软件结合气压测漏法应用到安全阀密封性能检测中。通过对单位时间压力下降值和气体泄漏量关系的研究，提出了一种简易高效准确的安全阀密封试验智能检测系统的设计方案，并重点阐述了计算机组态软件在检测系统中的开发应用。“,”Aim at the cumbersome, inefficient, poor accuracy and reliability problems of the traditional artiifcial bubble counting method for safety valve seal test, the method combining computing conifguration software and pressure leak detection method is applied to the relief valve sealing performance tests. By the relationship research of gas leakage quantity and pressure drop value per unit time, this paper puts forward a intelligent detection system design scheme of a simple and efifcient accurate relief valve seal test, and expounds the calculation unit conifguration software development and application in detection system.
