摘要(Abstract):

通过对安全阀失效原因的分析 ,得出介质腐蚀性、粘度、温度压力是使安全阀失效的因素 ,同时也是影响安全阀校验周期的因素。提出以整压比来表示压力因素的影响 ,并对安全阀校验周期同温度整压比之间的关系进行了试验研究。基于校验周期同温度整压比以及同介质腐蚀性、粘度的关系 ,建立了安全阀校验周期的识别模型。
It is shown that medium causticity,adhesiveness,temperature and pressure are factors of safety valve lapse and safety valve inspection time based on the analysis the reasons of safety valve lapse. The pressure factor with ratio of set pressure and normal pressure is expressed, the connection of temperature and ratio of set pressure and normal pressure with safety valve inspection time is investigated and the safety valve inspection time identification model is set up based upon the connection of temperature and ratio of set pressure and normal pressure and medium causticity and adhesiveness with safety valve inspection time.
