如何订购 how to order |
阀门上的流量数据Cv值 (2) Flow Data Cv Values for Valves (2) |
美国尼伯科有限公司 |
液流: 在此:Q = 液流量(每分钟加仑数) |
气流:
注意:△P 必须小于 0.5 P1 (当△P 大于 0.5 P1时流量处于临界值.) |
阀门通径 Valve Sizes |
(节流系数) 阀瓣部分开启时可用于节流应用。用节流系数乘于流量系数。 注意:闸阀不能用于节流。 (THROTTLING FACTORS) For throttling use with disc partially open. Multiply Cv by factor. NOTE: Gate valves are not throttled. |
