[0036] In summary, when in use, the water in the water inlet pipe 1 is extracted by the circulation pump 4 through the exhaust pipe 21 and the connecting pipe 3. When the water inside the water inlet pipe 1 contains air, the liquid level inside the exhaust frame 22 drops, and the float 237 moves downward. The float 237 drives the piston plate 235, the movable rod 236 and the tooth plate 238 to move downward, and the elastic potential energy is generated by the spring 234, which assists the piston plate 235 and the movable rod 236 to move downward.

The air enters the box body 241 through the conduit 23113, and the water contained in the exhausted air is retained in the box body 241, and the air is discharged through the exhaust port 243 at the top of the box body 241.

[0037] When exhausting the exhaust frame 22, the internal pressure of the exhaust frame 22 decreases, and the movable valve plate 2313 and the movable pipe 2315 move downward by their own weight. The movable pipe 2315 moves downward to drive the transmission rods 23181 of the automatic valve 1 2318 and the automatic valve 2 2319 to rotate downward. At this time, when the water supply pipe 231 is opened, the drain pipe 2316 is closed, and water is injected into the valve body 2311 through the drain pipe 2316. The injected water enters the exhaust frame 22 through the valve port 2312 to replenish water inside the exhaust frame 22.

[0038] After the liquid level inside the exhaust frame 22 rises, the float 237 moves up to close the valve 23111 of the exhaust pipe 23110, and the movable valve plate 2313, the float 2314 and the movable pipe 2315 move up. The movable valve plate 2313 moves up to close the valve port 2312, and the movable pipe 2315 moves up to drive the automatic valve 1 2318 and the automatic valve 2 2319, so that the water supply pipe 2317 is closed when the drain pipe 2316 is opened, and the water at the top of the valve port 2312 is discharged through the drain pipe 2316 and enters into the box body 241 through the conduit 23113. The water inside the box body 241 can be discharged by opening the drain valve 244.

The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
