Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, and in particular to a self-cleaning ball valve. Background Technology

[0002] Currently, ball valves are indispensable in industrial, civilian, and automotive manufacturing fields. A ball valve is a valve in which the opening and closing element (ball core) is driven by the valve stem and rotates around the ball valve axis. In pipelines, ball valves are mainly used for cutting off, distributing, and changing the flow direction of the medium. It can close tightly with only a 90-degree rotation and a very small torque.

[0003] Existing ball valves generally do not have a self-cleaning function. Tiny solid particles in the medium will adhere to the ball core, causing the ball core to rotate and rub against the sealing element, which can easily cause wear on the sealing element and affect the service life of the ball valve. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a self-cleaning ball valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A self-cleaning ball valve includes a valve body and a valve cover. A ball core is installed in the valve body, and the valve cover is installed on the valve body. A rotating assembly is installed on the valve cover for rotating the ball core. A sealing ring is provided in the valve body for sealing the outer circumference of the ball core. An installation block is embedded in the sealing ring, and a scraper is installed on one side of the installation block. The scraper is in contact with the outer surface of the ball core for cleaning the ball core.

[0007] Preferably, the rotating assembly includes a valve stem and a handle, the valve stem being movably connected to the valve body and valve cover and the ball core, and the handle being mounted on the top of the valve stem.

[0008] Preferably, a fixing component is installed at the top of the throttle for mounting the throttle on the valve stem, and the fixing component is a bolt.

[0009] Preferably, an opening is provided on one side of the valve body, and the valve cover is installed at the opening of the valve body through a flange assembly, with the opening corresponding to the position of the sealing ring.

[0010] Preferably, a connecting pipe is provided on one side of the scraper, and several water outlets are opened on the connecting pipe. The positions of the several water outlets correspond to the scraper. One end of the connecting pipe extends through the valve body and out of the valve body. Water is drawn by a water pump connected to one end of the connecting pipe and sprayed out through the water outlet to clean the scraper.

[0011] Preferably, one side of the scraper is provided with an arc-shaped portion.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, by setting a ball core, allows the ball core to be rotated via a rotating component during use. During the rotation of the ball core, a sealing ring seals the outer circumference of the ball core. Simultaneously, a scraper located within the sealing ring cleans the outer circumference of the ball core, reducing wear during rotation and increasing its service life. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Reference Figures 1 to 7 A self-cleaning ball valve includes a valve body 1 and a valve cover 2. A ball core 3 is installed inside the valve body 1. The valve cover 2 is mounted on the valve body 1 and has a rotating assembly for rotating the ball core 3. A sealing ring 4 is provided inside the valve body 1 for sealing the outer circumference of the ball core 3. An installation block 6 is embedded in the sealing ring 4. The installation block 6 is arc-shaped. A scraper 7 is installed on one side of the installation block 6. The scraper 7 is in contact with the outer surface of the ball core 3 for cleaning the ball core 3. A sealing surface 16 is provided on one side of the sealing ring 4. The sealing surface 16 is in contact with the outer circumference of the ball core 3 for sealing the outer circumference of the ball core 3.

[0026] In use, this device features a ball core 3 that can be rotated via a rotating assembly. During rotation, a sealing ring 4 seals the outer circumference of the ball core 3. Simultaneously, a scraper 7 located within the sealing ring 4 cleans the outer circumference of the ball core 3, reducing wear and increasing its service life.

[0027] Furthermore, the rotating assembly includes a valve stem 8 and a handle 9. The valve stem 8 movably passes through the valve body 1 and the valve cover 2 and is connected to the ball core 3. The handle 9 is installed at the top of the valve stem 8. By using the handle 9, the valve stem 8 can be rotated, thereby rotating the ball core 3 and allowing water to pass through the valve body 1.

[0028] Furthermore, a fixing component 10 is installed at the top of the throttle 9 for mounting the throttle 9 on the valve stem 8. The fixing component 10 is a bolt. Through the fixing component 10, the throttle 9 can be connected to the valve stem 8, preventing the throttle 9 from separating from the valve stem 8.

[0029] Furthermore, an opening 13 is provided on one side of the valve body 1, and the valve cover 2 is installed at the opening 13 of the valve body 1 through the flange assembly 11. The opening 13 corresponds to the position of the sealing ring 4. Through the opening 13, the valve cover 2 can be removed from the valve body 1 through the flange assembly 11 during use.

[0030] Furthermore, an arc-shaped portion 14 is provided on one side of the scraper 7. Through the arc-shaped portion 14 provided on one side of the scraper 7, the scraped-off impurities can be guided towards the water inlet of the valve body 1, so that the impurities on the scraper 7 can be cleaned by the water flow.

[0031] Furthermore, a connecting pipe 12 is provided on one side of the scraper 7, and a plurality of water outlets 15 are provided on the connecting pipe 12. The positions of the plurality of water outlets 15 are all corresponding to the scraper 7. One end of the connecting pipe 12 extends movably through the valve body 1 and out of the valve body 1. Water is drawn by a water pump connected to one end of the connecting pipe 12 and sprayed out through the water outlets 15 to clean the scraper 7. Water can be drawn by the external water pump (not shown in the figure) and sprayed out through the water outlets 15 through the connecting pipe 12 to clean the scraper 7.

[0032] Example 2

[0033] In this embodiment, a plurality of scrapers 7 (such as...) are provided on one side of the mounting block 6. Figure 8 As shown), it is used to clean the surface of the ball core 3 multiple times. The scraper 7 and the mounting block 6 are both annular. There is a certain distance between each pair of the scrapers 7. The annular scrapers 7 are arranged in concentric rings in multiple layers on the mounting block 6 in the radial direction (from the inner cavity of the mounting block 6 inward, pointing to the center of the annular mounting block 6). When the ball core 3 is rotated, the arc-shaped part 14 of the scraper 7 is attached to the outer surface of the ball core 3 to ensure that the surface of the ball core can be effectively cleaned. By setting multiple scrapers 7, the surface of the ball core 3 can be cleaned multiple times, increasing the cleaning effect of the ball core 3. In addition, a connecting pipe 12 is provided on one side of the scraper 7, so that water can be sprayed out through the outlet 15 through the connecting pipe 12 to clean the scraper 7.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
