- the plurality of taper ribs 21 are configured to protrude on the outer circumferential surface at equal intervals in the circumferential direction, so that the plurality of bubble risers 22 are provided between the plurality of taper ribs 21.
- valve protrusion wheel 23 having a diameter smaller than that of the valve moving groove 15 is protruded in the upper center of the float 20 so as to open and close the air discharge hole 16.
- the upper end of the valve protrusion wheel 23 is preferably provided with a silicon packing 23a for good adhesion to the air discharge hole 16, and is shown in FIG. As described above, the silicon packing 23a is preferably provided with a circular protrusion 16a for good adhesion.
- An air waiting chamber 24 is preferably provided between the plurality of tapered ribs 21 of the float 20 and the valve protrusion wheel 23 in the center, and in this case, the valve protrusion wheel part is higher than the upper end of the tapered rib 21. (23) It is desirable to have the upper end configured to have a relatively higher upper end. However, in some cases, as shown in FIG. 5, only the valve protrusion wheel 23 may protrude from the upper end of the float 20.

- the vertical center line (not shown) of the air discharge hole 16 is shifted from each other, the float 20 is moved upward so that the tapered inner circumferential surface 131 and the taper as shown by the solid line in FIG. 5 are tapered.
- the valve protrusion wheel 23 is formed because the vertical center line (not shown) of the float 20 and the vertical center line (not shown) of the air discharge hole 16 are exactly matched.
- the air discharge hole 16 is to be in close contact with the function to automatically close.
- the fastening nipple portion 18 of the housing 10 is fixedly installed by being fastened to the pipe P, and water and bubbles flowing through the pipe P are obtained from the water supply hole 19. Inflow to the receiving chamber 12 through the).
- the air bubble buoyant in the state in which the lower portion is opened without moving the bubble (b) introduced into the inlet chamber 12 to be raised to the bubble riser 22 is opened.
- the buoyancy is generated so that the float 20 floats on the water W of the inlet chamber 12.
- the float 20 is moved to rise to the floating force due to the buoyancy generated by the air filled in the air buoyancy chamber 25 so that the valve protrusion part 23 will block the air discharge hole (16).

- the float 20 can be moved upwardly in a straight upward direction while being maximally suppressed from shaking in the left and right directions.
- the air buoyancy chamber 25 is filled to completely fill the air so that the float 20 is moved up by buoyancy, so that the valve protrusion wheel 23 is in a state of closing the air discharge hole 16. Since the bubbles (b) flowing into the inlet chamber 12 are prevented from entering the air buoyancy chamber 25, which is completely filled with air, the bubbles 20 are directly moved upwardly through the bubble riser 22, so that the float 20 ) Will be in the state to be gathered in the upper air waiting room (24).
- the air pressure in the air waiting room 24 is relatively weaker than the buoyancy of the air buoyancy chamber 25 rather than the air pressure.
- the present invention is almost blown in the process of moving bubbles or bubbles to rise along the bubble rise path 22, so that only the air is moved to rise.
- the bubble (b) entering into the bubble breaking groove 14 is instantaneously bursting as it comes into contact with the inner peripheral surface of the bubble breaking groove 14, or is automatically broken while being in contact with other bubbles (b) that continues to rise. .
- the bubble (b) is bursting, but the water particles are splashed, but the water particles are blocked by the air u-turn projection (17) is dropped in the downward direction and only the air is moved to the valve moving groove 15 by turning the air u-turn projection (17) Since the air is discharged to the air discharge hole 16, even if the bubble (b) is broken, the bursting water particles do not leak at all into the air discharge hole 16, and thus the present invention is directed to the air discharge hole (16) No water leaks, only air.
