[0024] During actual use, the valve plate 5 is hinged to the mounting frame 3 through the connecting shaft 8. In this embodiment, the upper and lower sides of the valve plate 5 adopt an arc structure, which increases the contact area between the valve plates 5 and the valve plates 5, ensures the stability of its closure, and at the same time ensures the stability of the equipment operation. Initially, several groups of valve plates 5 are in a closed state, and the cylinder 2 on the hinge seat 1 drives a group of connecting shafts 8 that pass through the side wall limit frame 4 of the mounting frame 3 to move. The limit frame 4 provides a limiting slide rail for the connecting shaft 8. At this time, several groups of connecting rods 6 connected to the connecting shaft 8 on the other side of the hinged plate are connected by the auxiliary plate 7 for synchronous movement. Several groups of valve plates 5 are controlled to move simultaneously by a single cylinder 2, which is convenient for adjustment and quick response. The protective component is used to ensure the stability of the equipment operation.

[0025] In this embodiment, the protection component includes a sliding frame 9 and a filter frame 11. The sliding frames 9 are arranged on the front and rear sides of the mounting frame 3.
