摘要
正确选取调节阀规格型号，必须充分了解调节阀门的流量特性及其实际运用中的畸变。在阀径计算和选型时关键在于正确选取用于计算的流量值和阀前后差压。
For the correct selection of hoes of regulating valves, we must fully understand the flow characteristics of the valve and deformity in practical applications. The key of calculation and selection of the valve is to select the correct now value and the differential pressure value between the valve front and back for calculation.
