氣動閥門執行器工作原理（單作用，雙作用）

雙作用氣動執行器工作原理，單作用帶彈簧複氣動執行器工作原理，氣動閥門的工作方式都是以靠氣動執行器壓縮空氣帶動閥門而工作的。

雙作用氣動執行器工作原理

双作用气动执行器工作原理

当气源压力从气口(2)进入气缸两活塞之间中腔时，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(4)排出，同时使两活塞齿条同步带动输出轴 (齿轮)逆时针方向旋转。反之气源压力从气口(4)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口(2)排出，同时使两活塞齿条同步带动输出轴(齿轮)顺时针方向旋转。(如果把活塞相对反方向安装，输出轴即变为反向旋转)

單作用帶彈簧複氣動執行器工作原理

双作用气动执行器工作原理

当气源压力从气口(2)进入气缸两活塞之间中腔时，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(4)排出，同时使两活塞齿条同步带动输出轴(齿轮)逆时针方向旋转。在气源压力经过电磁阀换向后，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(2)排出，同时使两活塞齿条同步带动输出轴(齿轮)顺时针方向旋转。(如果把活塞相对反方向安装，弹簧复位时输出轴即变为反向旋转)
