| 摘 要： | 该文首先阐明国际标准ISO6358定压法中对流量控制阀的流通能力的规定是不充分的,有可能导致测出的被测元件的C值和b值的严重失真.在此基础上,结合被测件下游配管的尺寸规格,提出对应的被测件的C值和b值的可测范围,作为利用定压法测量气动元件流量特性的使用注意事项.

| Abstract: | Comments on flow control valve is deficient in ISO6358 in-line test circuit,which may lead to measurement distortion of sonic conductance C and critical pressure ratio b in certain conditions.As precautions for in-line test,measurable range of C and b is proposed for downstream pressure-measuring tubes according to their size. |
