二位四通座阀式换向阀

二位二通和二位三通座阀式换向阀

概述

M-.SED型换向阀是电磁驱动的直动式座阀换向阀，用于控制流动的启动、停止及方向，主要由阀体（1）、电磁铁（2）、阀座（7）、（11）以及关闭元件（4）组成。

手动应急操作（6）可在电磁铁未通电时切换阀。

基本原理（二位三通座阀式换向阀） 

阀的初始状态为常开UK或常闭CK，由弹簧（5）的布置决定。关闭元件（4）后方的腔室（3）与P口相连，并与T口密封隔离，因此阀相对于电磁铁与弹簧驱动力实现压力补偿。

采用特殊关闭元件（4），P、A、T口均可承受350 bar最高工作压力，油液也可双向流动，参见符号！

初始位置时，关闭元件（4）由弹簧（5）压在阀座（11）上；切换后，则由电磁铁（2）压在阀座（7）上，流路截止。

二位二通座阀式换向阀的油箱口在内部封闭。

二位四通座阀式换向阀

二位二通和二位三通座阀式换向阀

在二位三通座阀式换向阀下方安装Plus-1叠加板，可实现二位四通座阀式换向阀功能。 

Plus-1 叠加板的功能

  • 初始位置：

主阀未动作时，弹簧（5）使关闭元件（4）压在阀座（11）上，P口封闭，A与T相通。由A连接至控制阀芯（8）大端面的控制管路卸压至油箱。P口压力将球（9）压向阀座（10），因此P与B相通，A与T相通。

  • 过渡位置：

主阀动作时，关闭元件（4）克服弹簧（5）移向阀座（7）并压紧。过程中T口封闭，而P、A、B会短暂互通。

  • 切换位置：

P 与 A 连通。泵压经 A 口作用于控制阀芯（8）的大面积上，将钢球（9）压在阀座（12）上，从而使 B 与 T 连通、P 与 A 连通。Plus-1 叠加板中的钢球（9）具有“正遮盖”。

 

注意！

使用差动缸时，为避免压力放大，必须将油缸的环形面积一侧连接至 A 口。

节流插芯。

若运行条件导致切换过程中可能出现超过阀性能极限的流量，则必须使用节流插芯。

示例：

  • 蓄能器运行，

  • 作为内部先导取油的先导控制阀使用。

二位二通和二位三通座阀式换向阀

节流插芯装入座阀的P口。

二位四通座阀式换向阀

节流插芯装入Plus-1板的P口。

 

单向阀插装件

单向阀插芯允许油液由P自由流向A，并以无泄漏方式封闭由A至P的流动。
