摘　　要：介绍了2D数字阀的基本结构及工作原理,提出了2D流量控制概念。研究了由径向力引起的液压卡紧现象。通过Fluent软件对数字阀内部进行流场分析,得出2D阀芯弓形槽处壁面所受的压力分布,并对阀芯受到径向力的原因进行了分析,提出了减小2D阀阀芯卡紧力的一些措施。The structure and working principle of 2D digital valve are first introduced in this paper. Then the way of 2D flow control is proposed. The hydraulic clamping caused by radial force is studied and the simulation of the internal flow field is processed with software Fluent. Then the pressure distribution on the wall of arcuate groove in 2D digital valve spool is gained. By analysis of the reason of the radial force, some measures which can prevent hydraulic clamping are carded out.
