在对安全阀校验现状进行分析的基础上 ,较详细地叙述了安全阀校验测试仪的设计。该测试仪可以对安全阀校验过程中压力和位移进行实时测量 ,自动识别和显示安全阀的开启压力和开启高度 ,并具有RS4 85数据通讯功能。
Based on the analysis of the status of safety valve calibration, the design of safety valve calibration tester is described in detail. The tester can measure the pressure and displacement during the safety valve real-time measurement, automatically identify and display the relief valve opening pressure and opening height, and has RS485 data communication.
