根据调节部位信号，自动控制阀门的开度，从而达到介质流量、压力和液位的调节。
According to regulate parts of the signal, the automatic control of valve opening, so as to achieve medium flow rate, pressure and level of regulation.
流量控制阀由电动执行器调节开度，可实现远距离控制阀门的开度，以满足系统计量的要求。
The open angle of the flow control valve is adjusted by electric actuator, which can be controlled remotely to meet the requirement of system measure.
由于阀门转轴通过曲肘连接水流挡板所以阀门的开度越大，絮凝剂加注量就越大。反之亦然。
As the valve rotating shaft is connected with the water flow baffle by the toggle, the opening of the valve is larger, the filling-up quantity of the flocculating agent is more.
