摘　　要：主要对几种常用的拖拉机PTO湿式离合器控制阀块进行了简单介绍,并针对拖拉机PTO湿式离合器控制阀块的工作原理及存在问题进行分析,提出一种性能更优的PTO湿式离合器电比例控制阀块。此控制阀块结构紧凑,冲击小,散热效果好,系统能耗较低,且可实现湿式离合器的柔性结合。In this paper,the wet clutch control valves of PTO were briefly introduced.This paper analyzed the working principle of the control valves and put forward an electric proportional control valve with better performance.The electric proportional control valve had tight structure,small impact force,good heat dissipation effect,low energy consumption of system,and realized the flexible combination and cutting of the clutch.
