Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The first embodiment is as follows: please refer to fig. 1-4, a double-plate type dustproof butterfly valve, which comprises a body 1, wherein the body 1 is a hollow round rod, the top of the body 1 is provided with a dustproof device 2, the dustproof device 2 comprises a bearing 21 fixedly installed on the top end of the side wall of the body 1, the top of the bearing 21 is provided with a cover plate 22, the bottom wall of the cover plate 22 is fixedly installed with a connecting rod 23 connected with the top wall of the bearing 21, a clockwise side wall of the connecting rod 23 is fixedly installed with a scraper 24 in the shape of an arc triangle, the side wall inclined on the scraper 24 is lower in height approaching the outside, the inner side wall of the bearing 21 is fixedly installed with a fixing rod 25, the fixing rod 25 penetrates through the outer side wall of the body 1 and extends to the inside of the body 1, and the top wall of the fixing rod 25 is fixedly installed with a turntable 26.

The working principle is as follows: when the dustproof device is used, the dustproof device 2 is located at the outer part, so that external dust can be accumulated at the joint of the fixed rod 25 and the bearing 21, when a worker rotates the fixed rod 25, the outer side wall of the fixed rod 25 can be in contact with the inner side wall of the scraper 24, the scraper 24 can scrape off the dust attached to the side wall of the fixed rod 25, the scraped dust can be accumulated on the side wall of the scraper 24, the height of the side wall surface inclined on the scraper 24, which is closer to the outer part, is lower, so that the dust accumulated on the side wall of the scraper 24 can fall to the outer part of the bearing 21 along the side wall of the scraper 24, and the situation that the dust on the fixed rod 25 is scraped off and accumulated into blocks is avoided.

Example two: on the basis of the first embodiment, please refer to fig. 1-4, a connecting device 3 is disposed inside the body 1, the connecting device 3 includes two butterfly plates 31 attached to the inner side wall of the body 1, rotating rods 32 rotatably connected to the inside of the body 1 are fixedly mounted at the upper and lower ends of the side walls of the two butterfly plates 31, movable grooves 33 are disposed at the ends of the two butterfly plates 31 that are far away from the side wall, fixed plates 34 are disposed at the ends of the two butterfly plates 31 that are close to each other, limiting grooves 35 corresponding to the two movable grooves 33 are disposed on the two fixed plates 34, limiting rods 36 are disposed at the ends of the two butterfly plates 31 that are close to each other, movable blocks 37 are fixedly mounted on the side walls of the two limiting rods 36, the four movable blocks 37 are hemispherical, the four movable blocks 37 are rotatably connected to the two movable grooves 33 and the two limiting grooves 35 corresponding to the positions of the movable blocks 37, a threaded frame 38 screwed with the side wall of the fixing rod 25 is fixedly mounted on one side wall surface of the two fixing plates 34 close to each other.

The working principle is as follows: when the butterfly valve is used, because the thread frame 38 is in threaded connection with the fixing rod 25, after the rotary disc 26 is rotated, the fixing rod 25 rotates along with the rotary disc 26, the thread frame 38 can move upwards or downwards, the fixing plate 34 is fixedly connected with the thread frame 38, the position of the fixing plate 34 can change, the butterfly plate 31 is connected with the fixing plate 34 through the limiting rod 36, when the fixing plate 34 moves, the butterfly plate 31 can be pulled to rotate around the rotary rod 32, the inside and the outside of the body 1 are communicated, the fixing rod 25 is in threaded connection with the thread frame 38, the butterfly plate 31 can be completely opened only by rotating the fixing rod 25 for multiple circles, and the effect of conveniently adjusting the water flow is achieved.

When the butterfly plate 31 is used, the movable blocks 37 are fixedly mounted on the two fixing plates 34, the movable blocks 37 are in a hemispherical shape, the movable blocks 37 are movably connected with the limiting grooves 35 or the movable grooves 33 corresponding to the positions of the movable blocks 37, when the fixing plates 34 move, the movable blocks 37 can rotate in the movable grooves 33 or the limiting grooves 35, and the fixing plates 34 move together, so that the situation that the butterfly plate 31 cannot move due to the fact that the fixing plates 34 are clamped is avoided.

Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above-described embodiments, and many modifications are possible. Any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention should be considered as belonging to the protection scope of the present invention.
