摘　　要：通过分析现行国家标准GB/T 20081.1—2021、GB/T 20081.2—2021,搭建一套能够用于气动减压阀流量-压力特性测试的电-气控制一体化试验台,以常规的直动式和先导式气动减压阀为试验客体进行关于流量-压力特性(按照国标GB/T 20081.1—2021,下同)和压力调节特性的测试,对测试数据编辑处理后进行分析,进而验证现行标准里阐述方法的可行性,为新国标中气动减压阀流量-压力特性测试的试验提供参考。Based on the analysis of the GB/T 20081.1—2021 and GB/T 20081.2—2021,a set of electro-pneumatic control integrated test-bed which can be used for flow and pressure characteristics test of compressed air pressure regulators is set up.The flow-pressure characteristics(according to GB/T 20081.1—2021,the same below)and pressure regulation characteristics of conventional direct operated and pilot-type compressed air pressure regulators are tested,and the test data are analyzed after editing and processing to verify the feasibility of the method described in the current standards.it provides a reference for the test of flow and pressure characteristics of compressed air pressure regulators in the new national standard.
