如何确定调节阀的CV值。？ c值定义definition of c value 水流经阀门的两端压差为100kpa时，某给定行程所流过以m3/h计，截至密度取kg/m3的流量数值，m2。 the value cv is the flow rate (m3/h) of pure water at normal temperature passing thrugh the valve when the valve disc is fully opened and the pressure differential between the two ends of the valve is (kg/cm2)100kpa q:最大流量（米3/小时） q: max. flow(m3/h) ρ:介质密度公斤/米3(取ρ=1) ρ: medium density (kg/m3) △p ：阀门压力损失，100kpa (公斤/厘米2) △p ：pressure loss in valve(kg/cm2) 查看更多
