Peformance:

In the exhaust state, the pontoon pulls down one end of the lever due to the force of gravity. At this time, the lever is in a tilted state, and there is a gap in the contact part of the lever and the exhaust hole. Air is discharged from the exhaust hole through this gap. After the water level rises, the buoy floats upward under the action of the buoyancy of the water. The sealing end face on the lever gradually presses the exhaust hole until the entire exhaust hole is completely blocked. The exhaust valve is now completely closed.
