0532003003插装式溢流阀

流量控制阀

功用:通过改变阀口过流面积来调节输出流量，从而控制执行元件的运动速度。

分类:节流阀、调速阀、温度补偿调速阀、分流集流阀。

常用节流口结构有锥形、三角槽形、矩形、三角形等。由节流方程知，当压力差.定时，改变开口面积即改变液阻就可改变流量。

节流阀实质相当于-一个可变节流口，借助控制机构使阀芯相对于阀体孔运动改变阀口的过流面积。

结构原理

主要零件有阀芯、阀体和螺母。阀体上右边是进油口，左边是出油口。阀芯一端开有三角尖槽，另-端加工有螺纹，旋转阀芯即可轴向移动改变阀口过流面积。为平衡液压径向力，三角槽须对称布置。

调速阀定差减压阀与节流阀串联而成，用来调节通过的流量自动补

偿负载变化的影响。

三通阀 由两个方向阀组件并联而成，对外形成一个压力油口、一个工作油口和一个回油口。三通插装阀的工作状态数取决于先导换向阀的工作位置数。

四通阀由两个三通阀并联而成

先导阀可以是一个三位四通换向阀

先导阀也可以是两个二位四通换向阀或四个二位三通换向阀

四通插装阀的工作状态数取决于先导换向阀的工作位置数。

电磁线圈是通电产生电磁的一种装置。在铁芯的外部缠绕与其功率相匹配的导电绕组，这种通有电流的线圈像磁铁一样具有磁性，它也叫做电磁铁（electromagnet）。我们通常把它制成条形或蹄形状，以使铁芯更加容易磁化。另外，为了使电磁铁断电立即消磁，我们往往采用消磁较快的的软铁或硅钢材料来制做。这样的电磁铁在通电时有磁性，断电后磁就随之消失。
