气动球阀，气动蝶阀90度旋转阀门工作原理Operation principle

双作用式Double acting
压缩空气从气口（B)进入气缸两活塞（c)之间中腔时，使两活塞分离向气缸两端方向移动，两端气腔的空气通过气口（A)排出，同时使两活塞（c)的齿条同步带动输出轴（d)，齿轮逆时针方向旋转90度，可以从两端调整微量角度，松动螺母（E)用内六角扳子拧动调节螺栓（F)调整所需角度，锁紧螺母，反之压缩空气则从气口（A)进入气缸两端气腔时，使两活塞向气缸中间方向移动，中间气腔的空气通过气门（b)排出，同时使两活塞（c)的齿条同步带动输出轴（D)齿顺时针方向旋转90度。
When compressed air goes into the middle cavity,which is between the two pistons in the cylinder through prot （B),it separates the pistons and make it move towards either end,while the air cavity on either end will be released from port（A),and at the same time ,the racks of two pistons simultaneously drive the output axis （D)（gear)to rotate mut.Contrarily, when compressed air goes into the air cavity on either end of the cyclider through port （A),the two pistons will move towards the center  of the cyclinder,and the air in the middle cavity willbe released from the port（B),and at the same time,the racks of two pistons syncronously drive the output axis（d)（gear)to rotate clockwkse of 90

单作用式（弹簧复位)Single acting（spring restore)
压缩空气从气口（B)进入气缸两活塞（c)口腔时，使两活塞分离向气缸两端方向移动，迫使两端的弹簧压缩，两端气腔的空气通过气口（A)排出，同时使两活塞（c)的齿条同步带动输出轴（D)（齿轮)逆时针方向旋转90度。在压缩空经过电磁阀换向后，气缸的两活塞在弹簧的弹力下向中间方向移动，中间气腔的空气从气口（B)排出，同时使两活塞（c)的齿条同步带动输出轴（D),（齿轮)顺时针方向旋转90度，可以从两端调整微量角度，松动螺母（E)用内六角扳手拧动调节螺栓（F)调整所需角度，锁紧螺母。
When compressed air goes into the middle cavity ,which is between the two pistons in the cylinder through port（B),it separates the pistons and make it move towards either end,thus make the spring compressed,while the air in air cavity on either end will be released from port（A),and at the same time,the racks of two pistons simultaneously drive the output axis （D)（gear) to rotate counter clockwise of
