对调节阀流量特性及放大系数K_v的研究

A Study on Flow Characteristic of Control Valves and Their Amplification Factors(K_v)

本文研究国内外常用的线性、等百分比、快开流量特性调节阀的放大系数 K_v,给出四种关子 K_v 的定义式和表达式.

Amplification factors(K_v) of control valves of linear,equal percentage and quick Opening flow characteristics usually used at home and abroad are studied in this pa- per ,and four definition expressions and formulae are obtained by author′s view.
