液压阀 方向控制阀 压力控制 流星控制阀 方向控制 方向控制阀控制液压系统中油液流动的方向或液流的通与断单向阀换向烟双向液压锁单向阀二、换向阔工作原理利用阀芯和阔体的相对运动使油路接通、关断或变换油流的方向，从而实现液压执行元件及其驱动机构的启动、停止或变换运动方向

分类

按操作方式分:手动换向阔、机动换向阀(亦称行程阀)、电磁换向阀、液动换向阀和电液换向阀等按阀芯工作时在阀体中所处的位置和换向阀所控制的通路数不同分:位通换向阀、二位二通换向阔、二位四通换向阀、二位四通换向阀等按阀的安装方式分:管式(亦称螺纹式)换向阀、板式换向阀和法兰式换向阀等按阀的结构形式分:滑阀式换向阀、转阀式换向阀和锥阀式换向阀等换向阀的图形符号方格数即"位”数，三格即三位箭头表示两油路连通，但不表示流向。表示油路不通。在方格内，箭头或”符号与方格的交点数为油路的通路.液控单向阀

功用

-允许液流正向流动，

反向是否允许流动由控制口X控制

工作原理

当控制油口X不通压力油时，油液只能从A-B

当控制油口X通压力油时，正、反向的油液均可自由通过
