摘　　要：在普通节流阀上用步进电机连接一个螺旋副机构 ,改进成为数字节流阀 ,并用PLC主控单元直接控制节流阀步进电机 。On the foundation of traditional choke valve, a screw pair mechanism is utilized to connect the stepping motor, so that the choke valve can be changed into a digital choke valve. In addition, the main control unit of PLC is applied in the direct control of the stepping motor of choke valve to satisfy the requirement of throttleable adjust speed under different working states.
