摘　　要：目前国内尚未对控制阀阶跃响应试验及方法进行强制要求,其研究也相对于国外处于落后水平。针对以上情况,以先进试验设备进行试验,研究控制阀的阶跃响应特性的意义,基于IEC 60534-9:2015 Industrial-process control valves-Part9标准的试验方法,以核级控制阀为例,梳理控制阀阶跃输入响应测量的试验条件,并逐步进行基准试验的测试、小阶跃试验的测试、响应时间试验的测试和数据采集,经过分析判定控制阀阶跃响应的意义和是否满足工艺系统需求。At present, there is no mandatory requirement for step response test and method of control valve in China, and its research is also backward compared with foreign countries. In order to study the significance of step response characteristics of control valves, the advanced test equipment is used to test the control valves, and the nuclear-grade control valves are taken as an example based on the test method of IEC 60534-9:2015industrial-proces control valves-Part9 standard, carding the test conditions of the step input response measurement of the control valve, and gradually carrying out the test of the benchmark test, the test of the small step test, the test of the response time test and the data acquisition, the significance of the step response of the control valve and whether it meets the requirements of the process system are analyzed and determined.
