针对IS06358规格中小口径气动元件的流量特性的测量方法规定的欠缺,使用一种口径转换的基准接头连接小口径元件进行流量特性的测量试验.通过和卡钳式测量方法的结果比较,从试验上确认了基准接头对于小口径元件的流量特性的影响程度.提出了压缩性流体用元件的声速流导和临界压力比的新的合成方法.将电磁阀本体和接头的合成结果与试验结果进行比较,结果一致,验证了所提案的合成方法的适用性,并探讨了利用新的合成方法计算阀本体的流量特性的可行性.

In the ISO6358 standard about determination of flow rate characteristics of pneumatic component,there lS no prescript to small valves.Using size converting standard fittings,flow rate characteristics experiment of the small valves with the standard fiaings were carried out.Compared to the results of caliper-type measurement,the effect of the standard fittings on the flow rate characteristics of small valve is confirmed.A new resultant method of flow rate characteristics is proposed.There is good agreement between the resuRant results and the experiment ones.It is proved applicable for the proposed resultant method.The feasibility of calculating the flow rate characteristics ofthe valve itselfis also discussed.
