[0011] This invention features a check valve with a lower valve plate and an upper valve plate slidably connected by a connecting rod. When air enters through the second air inlet pipe, the lower and upper valve plates move upward under the pressure of the air, allowing the gas to enter the aeration pipe through the first air inlet pipe for aeration. When the second air inlet pipe is closed, the lower and upper valve plates move downward under the weight of the connecting rod and the spring force, using the lower valve plate to close the first air inlet pipe. This facilitates control of the check valve's opening and closing, preventing water from being discharged through the air inlet pipe.

The air hole sealing mechanism includes a sealing rod provided through a connecting plate, and the sealing rod is inserted into the aeration hole for aeration. When air enters through the second air inlet pipe, the lower valve plate, the upper valve plate, and the connecting rod move upward under the action of air pressure, while the sealing rod is pulled out of the aeration hole for aeration. When the second air inlet pipe is closed, the lower valve plate and the upper valve plate move downward under the action of the gravity of the connecting rod and the spring force, and the sealing rod is inserted into the aeration hole to seal the aeration hole, achieving secondary sealing to prevent backflow and preventing foreign objects from entering and clogging the aeration hole when it is not in use, thus improving the flexibility and safety of the aeration hole.

[0013] This utility model features a piercing head at the lower end of the plugging rod, which is cone-shaped, allowing for the breaking down of impurities and clearing of blockages when the piercing head is inserted into the aeration hole. Attached Figure Description
