摘　　要：介绍了数字节流阀的工作原理及其控制系统的设计 ,利用步进电机直接接受微机控制并驱动液压阀阀芯产生一个轴向移动 ,从而改变节流口的通流面积来调节流量 。The operating principle as well as the control system designing of digital throttling valve is described. This system with stepbystep motor can be directly controlled by PC and drive the valve core of valve, which drives an axialdirection moving so as to modificate the area of throttling valve resulting in the adjustment of the flow. In this way, direct control can be fulfilled.
