摘　　要：针对三通2D数字阀传动机构和阀芯零位保持问题,设计了一种2D数字阀电-机械转换机构,实现了2D数字阀步进电机对阀芯径向运动的精确控制,并使阀芯在初始状态下轴向和径向保持在规定的零位位置。试验结果表明:该电-机械转换机构满足2D数字阀使用要求。An electro-mechanical converter of three-way 2D digital servo valve was designed in order to improve the transmission mechanism and zero-position holding mechanism. This improved converter was made the valve spool circumrotate accurately through the stepper motor and keep the valve spool at the prescriptive zero-position in the axial and radial direction. The experimental results show that the improved converter can meet the requirement of 2D digital servo valve.
