摘　　要：研究分析了目前常用安全阀公称流量特性测试技术及方法,针对其存在的重复性差、有效测试时间短等局限性,对关键元件进行了选型计算,改进了蓄能器式测试装置液压系统,实现了高压、大流量液体的可控输出,提高了有效测试时间及输出的稳定性,并介绍了数据采集软件的设计与实现。试验结果表明,该方法可直接测量安全阀公称流量溢流时的溢流压力及流量,并可打印输出,具有操作简单,界面人性化等特点。Analysis of the current common safety valve nominal flow characteristics testing techniques and methods, poor reproducibility for its existence, and shorter time to effectively test the limitations of the key elements of the selection calculation, improved accumulator type hydraulic system test, to achieve a controllable output pressure, large flow of liquid, improves the stability of the test time and the effective output, and introduces the design and implementation of data acquisition software. Experimental results show that this method can directly measure the pressure relief safety valve nominal flow rate and flow of relief when, and print output, simple, user-friendly interface and so on.
