Then the gas is transported, and the gas flows in the aeration pipe 1. The sliding disc 41 moves upward by the strength of the gas flow and the micro elasticity of the first spring 47, so that the sealing ring 43 is not attached to the inner wall of the connecting cylinder 3. Therefore, the gas is discharged into the water through the hole on the sliding plate and the air hole 412.
