3DREME10P-7X/200YG24K31F1M 德国力士乐Rexroth比例减压阀

力士乐Rexroth先导式比例减压阀R901218100 3DREME16P-7X/200YG24K31F1V ***现货

工作原理

先导式减压阀主要由阀体,主弹簧,主阀芯,主阀座,活塞,先导弹簧,先导阀芯,先导阀座,先导活

塞和调整弹簧等组成。拧动调节螺钉,压缩调整弹簧,顶开先导阀芯,介质从进口侧进入活塞上方,由

于活塞面积大于主阀阀芯面积,推动活塞向下移动,使主阀打开,由阀后压力平衡调节弹簧的压力改变

导阀的开度,从而改变活塞上方的压力,控制主阀芯的开度使阀后压力保持恒定。相比直动式减压阀,

先导式减压阀的远程控制口有个重要功能,即通过油管接到另一个远程调压阀(远程调压阀的结构和减压

阀的先导控制部分一样),调节远程调压阀的弹簧力,即可调节减压阀主阀芯上端的液压力,从而对减压

阀的出口压力实行远程调压,但远程调压阀所能调节的ZUI高压力不得超过减压阀本身导阀的调整压力。

先导式减压阀是采用控制阀体内的启闭件的开度来调节介质的流量,将介质的压力降低,同时借助阀后

压力的作用调节启闭件的开度,使阀后压力保持在一定范围内,在进口压力不断变化的情况下,保持出

口压力在设定的范围内,保护其后的生活生产器具。本类阀门在管道中一般应当水平安装

在同一系统中,往往有一个泵要向几个执行元件供油,而各执行元件所需的工作压力不尽相同的情况。

若某执行元件所需的工作压力较泵的工作压力低时,可在该分支油路串联一减压阀。油液流经减压阀后

,压力降低,且使与其出口处相接的某一回路的压力保持恒定。减压阀是一种自动降低管路工作压力的

专门装置,作用是在给定减压范围后,将阀前管路较高的压力降低至阀后管路所需的水平。减压阀广泛

用于高层建筑,城市给水管网水压过高的区域,矿井和气体管路等。
