Cv为额定流量系数,定义是阀门开到最大,在阀门的两边压差1PSI情况下,华氏60度清水时每分钟流经调节阀的流量数,以加仑/分计。
KV定义也是一样,只不过单位不一样,1BAR 的压差,每小时流过去水的礼服数。
换算为。CV=1.167*KV
Cv决定了阀门的流通能力,通过公式可以把你现场的工艺参数计算到标准的CV数值,从而对照阀门的额定CV 进行选择。
Cv is the rated flow coefficient, defined as the valve open to the maximum, the pressure difference in both sides of the 1PSI valve, 60 degrees of water per minute through several flow control valve, in gallons per minute meter.
The definition of KV is the same, but the unit is not the same, 1BAR differential pressure, flow of water per hour to dress number.
The conversion is. CV=1.167*KV
Cv determines the valve flow capacity, through the formula can take CV numerical calculation process parameters on your site to the standard, so as to control the rated CV valve selection.
