工作原理和结构特点
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。阀门由手柄驱动，通过手柄带动阀杆与凸轮旋转，凸轮具有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。
(1)六通阀的阀体由隔板分成两腔，每腔都有3个通道，中间为进油口，两端为出油口。阀体为碳钢板焊结构，体积小，质量轻，结构紧凑，提高了材料的利用率，缩短了生产周期，降低了成本。密封面堆焊不锈钢，防锈耐腐蚀，密封面经过精加工后抛光研磨，表面粗糙度Ra≤0.8μm。
(2)六通阀有两组密封组件。每组密封组件由阀瓣、密封圈、调整块、调节螺钉、夹板和螺栓组成。阀瓣为碳钢板焊件，设有加强筋，即增加阀瓣强度又起导向作用，保证每组阀瓣间的同轴度。阀瓣上镶嵌聚氨脂橡胶圈，该材料具有耐油、耐磨损、能稳定、密封良好和使用寿命长的特点。在凸轮的作用下，密封圈的球面与阀体密封面相接触产生挤压弹变形，达到密封效果。调整块和调节螺钉在两组密封组件不能同步到位时可起调整作用，确保各通道密封能同步到位。
(3)阀杆与阀体隔板和上阀盖间的轴向密封采用O形圈。
(4)阀体隔板及上阀盖轴孔部位镶有铜套，可减小与O形圈间的摩擦力矩，密封组件开启与关闭灵活，操作力矩小。
(5)上阀盖设有指示牌及限位螺钉，阀杆上安装指针，明确指示各通道的接通状况，易于操作
