A first sealing ring 3 is installed on the outer wall of the air valve baffle 2. A butt rod 4 is fixedly connected to one side of the first sealing ring 3. A second sealing ring 5 is installed on the outer wall of the air valve baffle 2. A butt joint groove 6 is opened inside the second sealing ring 5. Both the first sealing ring 3 and the second sealing ring 5 are of a slotted design, and the first sealing ring 3 and the second sealing ring 5 are respectively snap-connected to the rotating shaft 1. Glue is provided inside the butt joint groove 6, and the butt rod 4 is adhesively bonded to the second sealing ring 5 through the glue. The butt rod 4 is snap-connected to the second sealing ring 5 through the butt joint groove 6, and the butt rod 4 is arranged in an annular array centered on the central axis of the first sealing ring 3, which can improve the sealing performance of the end face of the air valve baffle 2.

[0023] Please refer to Figures 1-4 , a wind valve blade end face sealing structure. A polytetrafluoroethylene corrosion-resistant layer 7 is fixedly connected to the outer wall of the air valve baffle 2. An acrylic waterproof coating 8 is fixedly connected to the outer wall of the polytetrafluoroethylene corrosion-resistant layer 7. The polytetrafluoroethylene corrosion-resistant layer 7 is symmetrically arranged with respect to the central axis of the air valve baffle 2, and the polytetrafluoroethylene corrosion-resistant layer 7 is in close fit with the air valve baffle 2.
