1、计算出通过该阀门的水流量。
按样本提供的数据，并参考设备的接口尺寸，核对该规格阀门的流量是否满足要求。
2、选择适当的压差范围。
计算水系统的阻力，得出阀门需要吸收的压差，来确定该阀门的压差范围。.
3、根据计算出的流量、压差范围和技术要求来
确定适当的阀门系列、型号。
流量控制阀的压降等于其工作压差范围的最小压降值。
注：水泵扬程=动态流量平衡阀的压降+系统的其他压力。

1, calculate the water flow through the valve.
Data provided by the sample and reference device interface size, check whether the specifications meet the requirements of the flow valve.
2, select the appropriate pressure range.
Calculate the resistance of the water system, need to absorb the pressure valve obtained to determine the scope of the differential pressure valve. .
3, according to the calculated flow rate, pressure range and technical requirements to determine the appropriate valve, series.
Flow Control Valve pressure drop is equal to its scope of work the minimum pressure drop value.
Note: The pump lift = dynamic flow balance valve pressure drop + system of other pressures
