[0025] Working principle: First, when the valve body 1 is in use, the dust impurities are filtered through the filter plate 21 to prevent the dust impurities from entering the valve body 1 through the air inlet valve port 11 and the air outlet valve port 12 to damage the internal parts. When the filter plate 21 needs to be cleaned, the driving handle 220 drives the driving rod 210 to move, and the driving rod 210 drives the moving plate 27 to move. During the movement of the moving plate 27, the block 28 and the stabilizing plate 3 are driven to move. During the movement of the block 28 and the stabilizing plate 3, the first spring 2 6 and the second spring 31 are compressed and deformed. When the block 28 moves to a position completely away from the card slot 29, the mounting block 25 is removed from the mounting slot 24, and the filter plate 21 is removed from the first fixing slot 22 and the second fixing slot 23. Then, the driving force on the handle 220 is removed. At this time, the first spring 26 and the second spring 31 are elastically reset. Driven by the reset elastic force of the first spring 26 and the second spring 31, the moving plate 27, the block 28, the stabilizing plate 3, the driving rod 210, and the handle 220 are reset. The operator can then clean the filter plate 21. After the filter plate 21 is cleaned, the driving handle 220 is used to drive the driving rod 210 to move again. The driving rod 210 drives the moving plate 27 to move. The moving plate 27 drives the block 28 and the stabilizing plate 3 to move during the movement. During the movement of the block 28 and the stabilizing plate 3, the first spring 26 and the second spring 31 are compressed and deformed. When the block 28 moves to completely leave the mounting groove 24, the cleaned filter plate 21 is placed The first fixing groove 22 and the second fixing groove 23 are inserted into the mounting block 25, and the mounting block 25 is inserted into the mounting groove 24. When the mounting block 25 is completely inserted into the mounting groove 24, the driving force on the handle 220 is removed, and the first spring 26 and the second spring 31 are elastically reset. Under the action of the reset elastic force of the first spring 26 and the second spring 31, the movable plate 27 and the stabilizing plate 3 move, and the movable plate 27 drives the clamping block 28 to move. When the clamping block 28 is completely inserted into the clamping groove 29, the installation of the filter plate 21 is completed.
