摘　　要：爆破片装置流阻系数测试系统中试验介质流量控制的稳定性和精确性直接影响测试结果。本文通过分析探讨直接调节与节流方式调节两种流量控制方式的优缺点,提出了基于节流方式设计的数字阀的控制方案,其响应时间短、控制精度高等特点更加适用于气源有限的流量调节,不仅减少了流阻测试系统中设备和场地的成本投入,还符合国家节能减排的理念。The stability and accuracy of flow control in the flow resistance coefficient test system of bursting disc devices directly affect the test results.By analyzing and discussing the advantages and disadvantages of direct regulation and throttling flow control,this paper puts forward the control scheme of digital valve designed based on throttling,which has the characteristics of short response time and high control accuracy.It’s more suitable for flow regulation with limited gas source,it not only reduces the cost in the test system,but also in line with the national concept of energy conservation and emission reduction.
