  最大持续流量以管路流速每秒20英尺为计算基础。
  最大间歇流量以管路流速每秒25英尺为计算基础。
  阀门的流量系数Cv是指在15.5摄氏度温度下,产生1 psi压降的流量(美制加仑/分钟)。
  这里所述的流量系数是指阀门全开时的流量系数。
  Maximum continuous flow based on pipe line velocity of 20 ft. per second.
  Maximum intermittent flow based on pipe line velocity of 25 ft. per second.
  The Cv factor of a valve is the flowrate in USGPM at 60 degrees F that will cause a one psi drop in pressure.
  The factors stated are based upon a fully open valve.

  流量系数Cv可以应用在自下列等式中,以确定流量(Q)和压降(P):
  Cv factor can be used in the following equations to determine flow (Q) and Pressure Drop (P):

Q (流量) = Cv V P
Q (flow) = Cv V P
P (压降) = (Q/Cv)2
P (pressure drop) = (Q/Cv)2

  注:美国瓦茨堵漏-关闭阀的使用将中断整个系统或建筑物的所有流量,因此应该考虑对位于阀门下游的有关设备和工艺所造成的影响。如果认为防回流阀的第二止回阀的故障导致安全阀排放现象应该得到处理,则应该在防回流阀总成下游立即安置第二堵漏-关闭阀。
  NOTE: The use of the Watts Flood Protection - Shutdown Valve will stop all flow to the system or building and consideration should be given to the effects on equipment and processes located downstream of valve. If relief valve discharge due to a failure of the backflow preventer second check valve is a concern, a second Flood Protection - Shutdown Valve should be located immediately downstream of the backflow prevention assembly.
