摘要
电液比例技术发展迅猛,以其控制精度较高、结构简单、成本合理等优点在工业生产中获得了越来越来广泛的应用,它的发展程度也可从一个侧面反映一个,因而日益受到各国工业界的重视。
本设计的课题是二级电液比例节流阀。在对该阀各部分的结构、原理及性能参数进行详细分析的基础上,完成了功率级为二通插装阀,先导级为电液比例三通减压溢流阀,通径为34mm,最大流量为480L/min,,。
利用UG进行运动仿真实验,使设计更加的合理。

Abstract
The technology of electro-hydraulic proportional develops swiftly and violently, it has more and e the widespread application in the industrial production by its precision control, the simply structure, the reasonable cost and so on, its degree of development also might reflect a national hydraulic pressure industrial technology level from a side, so this technology received more and more value by the various countries' industrial field.
The topic of this graduation project is two stage electro-hydraulic proportional throttle valve. This design will first carry on detailed analysis to the structure, principle and function parameter of various part of this kind of valve, plete the structural design and the parameter design of the two stage electro-hydraulic proportional throttle valve ,this valve's main stage is cartridge valve ,its forerunner stage is three contacts reduced pressure overflow valve .This valve's rectum is 32mm,and its max regulated flow is 480L/min,the oil input port fixed working pressure is , the output port fixed working pressure is .
Using UG motion simulation experiment to make the design more reasonable
Keywords Electro-hydraulic proportional throttle valve Cartridge valves Proportion electro- ratio pressure overflow valve UG movement simulation
