如何使用流量系数:
How to use Cv
阀门流量系数(Cv)是表示阀门通过流体能力的数值。Cv越大,在给定压降下阀门能够通过的流体就越多。Cv值1表示当通过压降为1 PSI时,阀门每分钟流过1加仑15oC的水。Cv值350表示当通过压降为1 PSI时,阀门每分钟流过350加仑15oC的水。
Valve coefficient (Cv) is a number which represents a valve's ability to pass flow. The bigger the Cv, the more flow a valve can pass with a given pressure drop. A Cv of 1 means a valve will pass 1 gallon per minute (gpm) of 60oF water with a pressure drop (dp) of 1 PSI across the valve. A Cv of 350 means a valve will pass 350 gpm of 60oF water with a dp of 1 PSI.
