调节阀常用参数释义一、阀门的流量系数阀门的流量系数是衡量阀门流通能力的指标，流量系数值越大说明流体流过阀门时的压力损失越小。
国外工业发达国家的阀门生产厂家大多把不同压力等级、不同类型和不同公称通径阀门的流量系数值列入产品样本，供设计部门和使用单位选用。
流量系数值随阀门的尺寸、形式、结构而变化，不同类型和不同规格的阀门都要分别进行试验，才能确定该种阀门的流量系数值。
1.流量系数的定义流量系数：表示流体流经阀门产生单位压力损失时流体的流量。
由于单位的不同，流量系数有几种不同的代号和量值。
Cv值、Kv值、Av值Cv值定义：使用60F（15.6℃）的清水，在阀前后的差压为1psi （0.07kgf/cm²）的条件下，流过阀时的流量，以US gal/min表示。
Kv值定义：温度在5℃～40℃之间，水流过在规定的开启位置下压力损失为0.1MPa的阀门时每小时立方米数。
2.阀门流量系数的计算Cv=1.167KvCv=（106/24）*AvKv=（106/28）*Av3.流量系数的典型数据及影响流量系数的因素公称通径DN50mm的各种型式阀门的典型流量系数见表。
流量系数值随阀门的尺寸、形式、结构而变。
对于同样结构的阀门，流体流过阀门的方向不同。
流量系数值也有变化。
这种变化一般是由于压力恢复不同而造成的。
如果流体流过阀门使阀瓣趋于打开，那么阀瓣和阀体形成的环形扩散通道能使压力有所恢复。
当流体流过阀门使阀瓣趋于关闭时，阀座对压力恢复的影响很大。
当阀瓣开度为&#+ 或更小时，阀瓣下游的扩散角使得在两个流动方向上都会有一些压力恢复。
对于高压角阀，当流体的流动使阀门趋于关闭时流量系数较高，因为此时阀座的扩散锥体使流体的压力恢复。
阀门内部的几何形状不同，流量系数的曲线也不同。
阀门内部压力恢复的机理，与文丘里管的收缩和扩散造成的压力损失机理一样。
当阀门内部的压降相同时，若阀门内压可以恢复，流量系数值就会较大，流量也就会大些。
