摘要
针对安全阀离线检验所得整定压力与其在工作条件下整定压力存在差异这一问题,文中利用Solid Works建立三维模型,将所建模型导入ANSYS软件并将安全阀在工况条件下的温度场实现了数值模拟,并在此条件下将安全阀产生的热变形进行理论计算。理论分析结果表明:安全阀在工况温度下各施力部件会产生热变形,其整定压力也随之发生变化,应在工作状况下注意该影响因素,保证安全阀的有效运行。
The safety valve set pressure of offline test is different from the set pressure in the working conditions.The changes of safety valve structure in the condition of the working temperature were simulated by SolidWorks and ANSYS,and in the simulation condition the thermal deformation of the safety valve was calculated.The analysis results show that the safety valve produces thermal deformation in different temperature,and the setting pressure changes.The influencing factors under working condition should be valued to ensure the effective operation of safety valve.
