摘要
本文研究了国内外气动节流阀流量特性的各种表征参数及其试验方法。认为我国现行标准规定用有效截面积S 值来表征节流阀的流量特性是可行的,但其试验方法存在一些问题,并提出了改进意见。
Various specific parameters of flow characteristic of domestic and foreign-made pneumat-ic throttle valves and the related test method are studied in this article.It is feasible to specify the folw char-acteristic by effective cross section area,s,as specified in current standard,but there are some problems ex-isted in the test method,for which improving oppinion is suggested.
