摘要
脉管制冷机中各小孔阀门的开度是一个重要的操作参数，它是影响制冷机性能的关键参数之一。介绍了不同开度下、不同压力时小孔阀门流量测量方法和结果，由此可指导实验，并尝试用毛细管来替代各小孔阀门的可能性。
Opening ratio of valves(such as orifice,second inlet,et al)is important operating parameters and have great effect on the preformance of pulse tube refrigerators.This paper gave the method and some results of measurement of volume flow rate through valves under different opening ratio of valves and pressure in a pulse tube refrigerator.To make pulse tube refrigerator simple,we try to use capillary tubes instead of valves.
