摘　　要：介绍了水液压技术的概念及其特点,论述了直控步进式水压数字节流阀的工作原理及其控制系统的设计。利用步进电机接受微机控制,并驱动液压阀阀芯产生移动,从而改变节流口的通流面积进行流量调节,达到控制精度高的目的。The concept and features of pure water hydraulics And the operating principle as well as the control system designing of digital throttling valve are introduced in this paper; The system with stepper motor can be directly controlled by PC and drive the valve core of valve, which drives an axial - direction 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.
