摘　　要：分别介绍、对比了差压阀气密性试验及压差试验的方法,并提出了优化建议。结果表明,采用改进型单口压降法与测量升压法检测差压阀性能更为全面且效率高。The air-tightness test method for different pressure adjustment valves and the pressure difference test method are respectively described and compared,and suggestions for optimization are given.The result shows that it is more complete and efficient to apply the improved single port pressure drop method and the pressure rise measurement method to inspect the performance of the different pressure adjustment valve.
