Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Implementing the following steps:

referring to fig. 1-3, the utility model provides a sealed environment-friendly pneumatic gate valve, which comprises a valve body 1, wherein the valve body 1 is connected with a dust collection air pipe 2, the dust collection air pipe 2 is communicated with a dust collector and is used for absorbing dust in the valve body 1, so that the dust can be prevented from overflowing randomly, the valve is more environment-friendly, one end of the valve body 1 is fixed with a cylinder 3, the other end of the valve body 1 is provided with a valve body plug board 4, a pull rod 5 is connected between the valve body plug board 4 and the cylinder 3, the cylinder 3 drives the valve plug board 4 to move through the pull rod 5, so that the valve body 1 is opened and closed, sealing packing 6 is arranged in an upper gap and a lower gap between the valve plug board 4 and the valve body 1, the gap between the valve plug board 4 and the valve body 1 is reduced through the sealing packing 6, and materials can be reduced from entering the valve body 1, and the valve is different from the prior art:

in this embodiment, be close to the upper portion rotation of valve body picture peg 4 in the valve body 1 and be equipped with pivot 7, the side of pivot 7 is fixed with brush hair 8, install in the valve body 1 and drive pivot 7 pivoted actuating mechanism 9, when opening valve body picture peg 4, actuating mechanism 9 drives pivot 7 rotation, and pivot 7 drives brush hair 8 rotation, cleans the material that remains at valve body picture peg 4 upper surface through brush hair 8, prevents that the material from caking at valve body picture peg 4's surface, and the material that is cleaned is discharged outside valve body 1 through dust collection tuber pipe 2.

In this embodiment, the driving mechanism 9 includes two sprockets 91 rotatably mounted at two ends of the valve body 1, a chain 92 is connected between the two sprockets 91, wherein, a large gear 93 is fixed on the sprocket 91 close to the rotating shaft 7, a small gear 94 is fixed on the rotating shaft 7, the small gear 94 is meshed with the large gear 93, a connecting block 95 is fixed at one end of the pull rod 5 close to the rotating shaft 7, the connecting block 95 is fixedly connected with the chain 92, when the valve plug board 4 is opened, the cylinder 3 contracts to drive the pull rod 5 to move leftwards, the pull rod 5 moves to drive the chain 92 to roll, the sprocket 91 rotates clockwise, thereby driving the large gear 93 to rotate clockwise, the small gear 94 rotates anticlockwise to drive the rotating shaft 7 to clean residual materials on the valve plug board 4 through the bristles 8, and in the same way, when the valve plug board 4 is closed, the cylinder drives the pull rod 5 to move reversely, and drives the chain 92 to roll reversely, thereby enabling the rotating shaft 7 to roll clockwise, and the surface of the valve plug board 4 also plays a role of cleaning.
