阀门上的流量数据Cv值 Flow Data Cv Values for Valves |
美国尼伯科有限公司 |
液流: 在此:Q = 液流量(每分钟加仑数) |
这个方程式适用于湍流和粘性接近于水的液体。 |
警告 此表所包含的流体流量系数是计算值。 因此,它们是近似值, 不能用于非常重要的流量和压降计算中。 对于要求非常精确的流量测量和检测,必须对本样本中所提到的任何阀门具体操作。 当阀门开启小于 45° 时,建议不要采用球阀充当节流功能。 WARNING The Fluid Flow factors contained herein are calculated values. They are, therefore, approximations and cannot be used for highly critical flow or pressure drop calculations. For very precise flow measurements, tests must be conducted on any valve mentioned within this catalog. Throttling of Ball Valves is not recommended when valves are less than 45° open. |
