摘　　要：利用CFD技术模拟了电液控制阀的径向不平衡力和流量压差特性,并利用试验验证仿真研究的正确性。研究结果表明,大流量液压阀应尽可能保持流道对称性并增加径向过液孔数量。能为液压支架电液控制阀的设计提供一定的参考依据。Studies the unbalanced force and the pressure loss-flow relationship of the valve. The simulation results are verified though the experimental tests. Results indicate that the flow passages of the large flow valve should be kept symmetrical, and the radial holes of the valve should be as many as possible. Provide references to the design of electro-hydraulic control valve used on the hydraulic roof support.
