摘要
控制阀的能力以前用流通能力C表示,后来称流量系数。由于计算公式中运用不同单位,出现国际单位制流量系数Kv和英制流量系数Cv,故探讨三者的定义、单位及换算。
The flow capacity of control valve is represented by C before. In view of different units used in calculation equations, the SI unit flow coefficient Kv and the El unit flow coefficient Cv appeared. So, it is necessary to discuss the definitions, units and conversion among these coefficients.
