Abstract: The present disclosure is directed to a combination air valve that uses buoyancy to lift seals into place, preventing media from escaping from the valve. Once the seals are in place, pipeline pressure is used to open and close the valve. The combination air valve includes a piston assembly which includes a main disc, a piston head located above the main disc, a float below the main disc, and a float shaft joining the float to the piston. When no media is in the valve the float is at the bottom of the valve and the main disc is down, allowing gases to leave the valve. The float is lifted as media enters the valve, thus using buoyancy to lift the main disc into place, preventing media from escaping from the valve. Once the seals are in place, pipeline pressure is used to open and close the valve.

Abstract translation: 本公开涉及一种组合空气阀，其使用浮力将密封件提升到位，防止介质从阀门逸出。 一旦密封件就位，管道压力用于打开和关闭阀门。 组合空气阀包括活塞组件，其包括主盘，位于主盘上方的活塞头，主盘下方的浮子以及将浮子连接到活塞的浮子轴。 当阀门中没有介质时，浮子位于阀门底部，主盘下降，允许气体离开阀门。 当介质进入阀门时，浮子被提升，因此使用浮力将主盘提升到位，防止介质从阀门逸出。 一旦密封件就位，管道压力用于打开和关闭阀门。
