直动式溢流阀的三维建模设计

直动式溢流阀的三维建模设计摘要溢流阀是一种压力控制阀，在液压设备中主要起定压溢流，稳压，系统卸荷和安全保护作用。本文以一种压力为10Pa,流量为50L/min的直动式溢流阀为对象，设计了其整体结构，并对其零部件进行设计计算。最后使用So1 idWorks软件对直动式溢流阀的阀体、阀芯、阀盖等组件进行三维建模设计，根据零件装配关系进行装配，实现整体装配及运动仿真。关键词：溢流阀，SolidWorks,.三维建模AbstractRelief valve is a pressure control valve,which mainly plays the role of constant pressurerelief,pressure stabilization,system unloading and safety protection in hydraulic equipment.Inthis paper,a direct-acting relief valve with a pressure of 10MPa and a flow rate of 50L/min isused to design the overall structure and calculate the design of its components.Finally,SolidWorks software is used to model and design the body,spool,bonnet and other componentsof the direct-acting relief valve in three dimensions,and the assembly is carried out according tothe parts assembly relationship to realize the overall assembly and motion simulation.Key Words:Relief valve,SolidWorks,3D modeling目录摘要…Abstract.…第一章绪论1.1溢流阀的简介…。1.2溢流阀的结构1.3溢流阀的作用.….21.4国内外研究现状.21.5溢流阀的概况.3第二章直动式溢流阀的工作原理和特性52.1直动式溢流阀的工作原理.…。2.1.1调压原理及特点….62.2溢流阀的特性..6第三章直动式溢流阀的基本参数计算83.】设计要求8第四章弹簧的设计计算104.1静态特性计算104.1.1额定开度Xn计算…104.1.2按开启比率确定弹簧的预压缩量x1104.1.3确定弹簧的刚度Ks..114.1.4计算滑阀的最大开口量Xmax..114.2弹簧的设计计算114.2.1选择材料和许用切应力114.2.2弹簧钢丝直径.…11由弹簧直径d和弹簧中经D计算其旋绕比…11
