摘　　要：节流槽的流量特性是主要考虑的因素,节流槽的流量特性对主阀阀芯的运动起关键作用。运用Solid Works软件建立并合理简化了不同切割角的节流槽流场模型,运用Fluent软件对节流槽的流场进行了仿真,并研究了流体流向为正方向和反方向时的节流槽流场;根据节流槽的几何尺寸,推导出了节流槽过流面积的表达式,通过仿真数据,研究了不同切割角的圆缺型节流槽的流量与开度、压力的关系,为节流槽的设计和优化提供了理论依据。The flow characteristics of the throttling groove is the main considerations,The flow characteristics of throttling groove play akey role in the movement of main valve spool,The flow field model of throttling groove with different cutting angles was established andsimplified by using SolidWorks software,The use of Fluent software for flow grooves is simulated and studied the flow field of throttlingslot when the flow direction is positive and negative.According to the geometry of the notches are deduced from the orifice flow area,Through the simulation data to study the relationship of different cutting angle of segmental type grooves flow and opening pressure to providea theoretical basis for the design and optimization of grooves.
