DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a valve with a cleaning structure, including a valve body 1, connecting pipes 2 are connected to both sides of the valve body 1, a connecting plate 3 is connected to the valve body 1, a protective cover 4 is slidably installed on the valve body 1 through the connecting plate 3, a bearing is provided at the connecting portion of a rotating rod 12 and a supporting frame 11, a threaded rod 6 and a rotating wheel 7 are both arranged inside the connecting plate 3 and the protective cover 4, a plurality of slots 20 are provided on the inner wall of the connecting plate 3, the friction between the rotating rod 12 and the supporting frame 11 is reduced by the bearing, so that it is convenient to drive the paddle 13 to drive the scraper 15 to rotate, and by arranging the threaded rod 6 and the rotating wheel 7 in the protective cover 4, it can prevent workers from accidentally touching the rotating wheel 7, and reduce the contact between the threaded rod 6 and the outside world.

[0021] A partition 5 is connected to the inside of the valve body 1, and a threaded rod 6 is threadedly connected to the valve body 1. A rotating wheel 7 is connected to one end of the threaded rod 6, and a sealing plug 8 is connected to the other end of the threaded rod 6. The partition 5 is Z-shaped as a whole, and a through hole 9 is opened in the middle position of the partition 5. The sealing plug 8 is inserted into the through hole 9. The rotating wheel 7 can facilitate the staff to twist the threaded rod 6 so that the threaded rod 6 pushes the sealing plug 8 into the through hole 9, thereby controlling the flow of the liquid.

[0022] A slot 10 is provided on the connecting pipe 2, a sealing plate 21 is inserted into the slot 10, a pull plate 22 is connected to the sealing plate 21, and a filter screen 23 is connected to the sealing plate 21. By inserting the sealing plate 21 into the slot 10, the filter screen 23 filters out impurities in the liquid, thereby reducing foreign matter from flowing into the connecting pipe 2 and the valve body 1, and the plug-in connection method can facilitate the staff to disassemble and install the sealing plate 21 and clean the sealing plate 21 and the filter screen 23.

[0023] A support frame 11 is connected to the inside of the connecting tube 2, and a rotating rod 12 is rotatably connected between the two support frames 11. Driving blades 13 are connected to both ends of the rotating rod 12. A connecting ring 14 is connected to the rotating rod 12, and a scraper 15 is connected to the connecting ring 14. There are eight scrapers 15 distributed between the two connecting rings 14 in a manner symmetrically centered on the axis of the rotating rod 12. The scraper 15 is of spiral design and contacts the inner wall of the connecting tube 2. When the rotating rod 12 rotates, the connecting ring 14 is driven to rotate together, so that the scraper 15 scrapes off dirt and foreign matter attached to the inner wall of the connecting tube 2, and the rotation of multiple scrapers 15 together can improve the scraping efficiency.

[0024] A handle 16 is connected to the protective cover 4, and grooves 17 are provided inside both sides of the protective cover 4. A spring 18 is connected to the groove 17, and a block 19 is connected to one end of the spring 18. The side of the block 19 away from the spring 18 is spherical in design. The block 19 slides in the groove 17 and fits into the slot 20. Through the spherical design on one side of the block 19, the inner wall of the connecting plate 3 can flexibly and quickly push the block 19 to move, thereby facilitating the staff to install and disassemble the protective cover 4.

[0025] The working principle of the utility model is:

[0026] The staff first inserts the sealing plate 21 into the slot 10, and then rotates the threaded rod 6 by twisting the rotating wheel 7 to disengage the sealing plug 8 from the through hole 9, so that the liquid flows in the connecting pipe 2. The flow of liquid will push the driving blade 13 to rotate, so that the driving blade 13 can drive the rotating rod 12 to rotate, prompting the scraper 15 to rotate to scrape off foreign matter and dirt attached to the wall of the connecting pipe 2, thereby cleaning the connecting pipe 2 to prevent dirt accumulation from affecting the flow of liquid. Then, the protective cover 4 is inserted into the connecting plate 3. With the protective cover 4, the connecting pipe 2 is cleaned and the protective cover 4 is removed. When the protective cover 4 is inserted, the block 19 will be pushed into the groove 17 by the inner wall of the connecting plate 3 to compress the spring 18, so that the block 19 is stuck in the groove 20 through the rebound of the spring 18, and the protective cover 4 is fixed, so that the protective cover 4 can protect the runner 7 and the threaded rod 6, and the filter screen 23 on the connecting pipe 2 on one side of the valve body 1 can filter out impurities in the water and reduce the impurities entering the valve body 1, while the filter screen 23 on the connecting pipe 2 on the other side of the valve body 1 can prevent the scraped dirt from flowing out with the liquid.
