摘　　要：目前,安全阀的开启、关闭压力、压力波动值等特征参数的判断均由试验人员结合经验总结出来,准确度有待验证。针对该问题,文章提出了一种新的适用于安全阀小流量特性试验数据自动采集处理方法;以柱塞式安全阀为例分析了安全阀小流量溢流过程,给出了试验所采用的液压系统简图,详细介绍了数据采集处理软件的设计与实现。试验结果表明,该方法可直接测量安全阀溢流过程中的开启压力、关闭压力、最大压力和最小压力以及压力波动值等特征参数,并自动判断这些特征参数是否符合《MT419—1995液压支架用阀》标准的要求,具有操作简单、界面人性化等特点。At present,the judgment of characteristic parameters of opening pressure,closing pressure and pressure fluctuation value of safety valve are all summarized by test personnel according to experience.The accuracy of these data should be verified.In view of the problem,the paper proposed a new automatic data collection and processing method suited for characteristic experiment of safety valve with small flow.It analyzed overflow process of small flow by taking plunger type safety valve as example,gave diagram of hydraulic system used in the experiment,and introduced design and implementation of the data collection and processing software in details.The experiment result showed that the method can directly measure characteristic parameters of opening pressure,closing pressure,maximum pressure,minimum pressure and pressure fluctuation value in overflow process of safety valve,and can automatically judge whether these data accord with demands of the standard of MT419-1995 the valve for hydraulic support. It has features of simple operation and interface humanization.
