Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ball valves, in particular to a double-scraper self-cleaning valve core. Background Art
[0002] When the valve core of a conventional ball valve is open, it is hidden within the valve body. During material transportation, impurities such as dust easily accumulate in the gap between the valve core and the valve body. Over time, the transported medium accumulates and solidifies, making the valve difficult to close or even completely unable to open or close. If any of these conditions occur, the valve typically needs to be returned to the factory for repair, removing the accumulated material or replacing the damaged valve core, which undoubtedly increases production costs. Therefore, a self-cleaning valve core that can remove accumulated material is urgently needed. Utility Model Content

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0014] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0015] Reference Figure 1-2 The present invention provides a double-scraper self-cleaning valve core, comprising an arc plate 1, with arc-shaped side plates 2 fixedly connected to both sides of the bottom surface of the arc plate 1. The two arc-shaped side plates 2 are symmetrically arranged, and each arc-shaped side plate 2 is provided with a scraper assembly for scraping off accumulated materials. The end of the arc-shaped side plate 2 away from the arc plate 1 is provided with a mounting hole 3. By providing the scraper assembly on the valve core, the space between the valve core and the valve body can be increased, and the weight of the valve core can be reduced while ensuring structural stability. It can effectively reduce material accumulation. Even if material accumulates, the scraper assembly can scrape off the accumulated material during the movement of the valve core, so that the valve core can achieve self-cleaning during movement without affecting the normal opening and closing operation of the valve core. The valve core does not need to be frequently replaced and repaired, thereby reducing production costs.
[0016] A further optimized solution is that the scraper assembly includes two inclined grooves 4 provided on the outer wall of the curved side plate 2. The two inclined grooves 4 are symmetrically arranged about the middle portion of the curved side plate 2. A scraper 6 is formed at the junction of the two inclined grooves 4. The thickness of the sides of the curved side plate 2 is less than the thickness of the middle portion of the curved side plate 2. By symmetrically providing the two inclined grooves 4 on the curved side plate 2, a scraper 6 is formed at the contact position between them. The curved side plate 2 can scrape away accumulated materials during the movement of the valve core. At the same time, the sides of the curved side plate 2 are transformed into a thinner sheet structure due to the inclined grooves 4, which can cut the accumulated materials, reduce the resistance of the materials to the valve core, and also reduce the wear on the valve core, thereby increasing the service life of the valve core and reducing maintenance costs.
[0017] As a further optimization solution, an annular gasket 5 is fixedly connected to the arc plate 1. The annular gasket 5 is located on the outer circumference of the arc plate 1 and is arranged corresponding to the valve seat. During the opening and closing process of the valve, the annular gasket 5 moves with the arc plate 1. During the movement, it will contact the valve seat and generate friction, which can remove impurities attached to it. Furthermore, the annular gasket 5 is a spray-coated special sealing material. By fixing the high-strength annular gasket 5 on the arc plate 1 and directly cooperating with the valve seat, the contact between the arc plate 1 and the valve seat is avoided, and the material strength of the arc plate 1 can be reduced to a certain extent, thereby achieving the purpose of reducing costs and increasing efficiency.
[0018] In a further optimization scheme, one mounting hole 3 is a hexagonal through hole, and the other mounting hole 3 is a circular through hole. The circular through hole ensures that the curved side plate 2 can be installed and rotated within the valve body, while the hexagonal through hole is for cooperation with the switch. Turning the switch drives the curved side plate 2 to rotate, and in turn drives the entire valve core to rotate, allowing it to open and close as needed.
[0019] The working process of the utility model: when in use, the switch cooperates with the inner hexagonal through hole to drive the arc side plate 2 to rotate, and then drives the arc plate 1 to rotate, so that it can control the opening and closing of the channel to ensure the normal operation of the ball valve. During the movement, the annular pad 5 arranged on the arc plate 1 can continuously contact the valve seat, thereby scraping off the materials adhered and accumulated at the annular pad 5. At the same time, the arc side plate 2 with the inclined groove 4 is a structure that is thick in the middle and thin on both sides. The scraper 6 formed in the middle can scrape off the accumulated materials, and the cutting knives formed on both sides can cut the accumulated materials, thereby ensuring the normal movement of the valve core and reducing the friction and obstruction of the accumulated materials on the valve core. While ensuring that the valve core can work normally, the service life of the valve core is increased, the frequency of its maintenance and replacement is reduced, and the production cost is reduced.
