换向阀是具有两种以上流动形式和两个以上油口的方向控制阀。是实现液压油流的沟通、切断和换向,以及压力卸载和顺序动作控制的阀门。
REXROTH力士乐电磁阀,REXROTH电磁换向阀,REXROTH柱塞泵,,REXROTH变量泵,REXROTHREXROTH比例阀,REXROTH节流阀,REXROTH流量阀,REXROTH溢流阀,REXROTH单向阀,REXROTH电液方向阀,REXROTH比例伺服阀,REXROTH叶片泵,REXROTH齿轮泵,博世BOSCH气动产品(力士乐Rexroth气动产品已更名安沃驰AVENTICS)
六通换向阀主要由阀体、密封组件、凸轮、阀杆、手柄和阀盖等零部件组成(图1)。阀门由手柄驱动,通过手柄带动阀杆与凸轮旋转,凸轮具有定位驱动与锁定密封组件的开启与关闭功能。手柄逆时针旋转,两组密封组件分别在凸轮的作用下关闭下端的两个通道,上端的两个通道分别与管道装置的进口相通。反之,上端的两个通道关闭,下端两个通道与管道装置的进口相通,实现了不停车换向。
