Description

Technical Field

[0001] This utility model relates to the field of high-pressure ball valve technology, specifically to an anti-jamming high-pressure ball valve. Background Technology

[0002] A high-pressure ball valve is a type of valve used for high-pressure fluid control, commonly found in industrial piping systems, especially in high-pressure environments such as oil, gas, power, and chemical plants. Its main function is to open, close, regulate, or cut off the flow of fluid.

[0003] Currently, high-pressure ball valves on the market are mainly composed of a valve body, ball core, valve seat, valve stem, sealing ring, and drive mechanism. The valve seat is mainly connected to the bottom of the ball core, while the valve stem is mainly connected to the top of the ball core and the drive mechanism. Users need to use the drive mechanism to make the valve stem drive the ball core to rotate, thereby achieving the opening and closing operation. However, because there are often some rotation gaps between the valve body and the ball core, when the fluid being transported by the equipment contains impurities, these impurities will enter the gaps. When these impurities accumulate to a certain level, they will prevent the ball core from rotating freely, causing a jamming phenomenon. Furthermore, because the valve seat is often fixed, the ball core must not only resist the frictional force generated by the high pressure when rotating, but also resist the frictional force between the ball core and the valve seat. This requires users to expend a lot of force to drive the ball core. Moreover, because the drive position is singular, when the frictional force between the ball core and the valve seat becomes large due to prolonged use, it may also cause jamming and inability to rotate. Utility Model Content

[0004] This invention proposes an anti-jamming high-pressure ball valve, which solves the problems in related technologies where the accumulation of impurities in the fluid to a certain value leads to the ball core being unable to rotate freely and the single drive position being unable to cope with the increased friction at the bottom of the ball core.

A protective plate is screwed to the top of the valve guard plate, and a second driving assembly is rotatably connected to the inner wall of the protective plate. A second passive assembly is rotatably connected to the top of the inner cavity of the protective plate, and the second passive assembly is drive-connected to the second driving assembly. The ball core is installed inside the valve guard plate via the first and second passive assemblies.

[0011] Preferably, the buffer assembly includes a spring rod, a sliding plate is fixedly connected to the top of the spring rod, a transfer groove is formed on the top of the sliding plate, and the bottom of the support plate is located inside the transfer groove.

[0012] Preferably, the second drive assembly includes a second drive handle, and a third bevel gear is fixedly connected to the outer surface of the second drive handle near the second passive assembly.

[0016] 1. In this utility model, the first and second passive components secure the top and bottom of the ball core, allowing the ball core to be stably installed inside the valve guard plate. This prevents the ball core from shifting and jamming during use. Because both the first and second passive components are rotatably connected, and because the first and second passive components are connected by transmission, the user can apply rotational force to either the first or second drive component as needed. This allows the first and second passive components to generate rotational force on the top and bottom of the ball core, thus eliminating the possibility of the ball core jamming due to excessive friction at a certain point, thereby improving the practicality of the equipment.

[0017] 2. In this utility model, by applying a certain amount of electricity to the side guard assembly, a certain magnetic attraction force is generated inside the side guard assembly, which can then adsorb impurities in the liquid flowing inside the equipment, thereby preventing impurities from entering the gap between the ball core and the valve guard plate, thus eliminating the phenomenon that the ball core cannot rotate freely due to excessive accumulation of impurities.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1

[0028] like Figures 1-6 As shown, this embodiment proposes:

[0029] A high-pressure ball valve designed to prevent jamming includes a valve guard plate 1 and a ball core 2. The ball core 2 has a cross groove at its top and a cylindrical groove at its bottom. A second sealing groove is also provided at the bottom of the ball core 2, and a sealing ring is installed inside the second sealing groove. Limiting grooves are provided at the front and rear ends of both sides of the valve guard plate 1. First sealing grooves are also provided on both sides of the valve guard plate 1. Side protection components 3 are screwed to both sides of the valve guard plate 1. The side protection components 3 include side protection plates 11. Limiting rods 15 are fixedly connected to the front and rear ends of the side protection plate 11 closest to the center of the valve guard plate 1, providing limiting... The inner diameter of the groove is adapted to the outer diameter of the limiting rod 15. A sealing ring 16 is fixedly connected to the side of the side guard plate 11 near the center of the valve guard plate 1. The inner surface of the first sealing groove is in contact with the outer surface of the sealing ring 16. A base 4 is screwed to the bottom of the valve guard plate 1. A first driving assembly 5 is rotatably connected to the inner wall of the base 4. A first passive assembly 6 is rotatably connected to the bottom of the inner cavity of the base 4. The first passive assembly 6 includes a first rotating rod 19. The top of the first rotating rod 19 extends through the base 4 into the interior of the mounting groove. The first rotating rod 19 is located on the outer surface of the mounting groove. A rotating disk 21 is fixedly connected to the surface, and a push rod 22 is fixedly connected to the top of the rotating disk 21. The inner diameter of the cylindrical groove is adapted to the outer diameter of the push rod 22. A support disk 23 is fixedly connected to the bottom of the push rod 22. The first passive component 6 is connected to the first drive component 5. An installation groove is opened at the bottom of the inner cavity of the side guard component 3. A buffer component 7 is fixedly connected to the bottom of the installation groove. The buffer component 7 includes a spring rod 24. A sliding plate 25 is fixedly connected to the top of the spring rod 24. A rotation groove is opened at the top of the sliding plate 25. The bottom of the support disk 23 is located at... Inside the transfer slot, a protective plate 8 is screwed to the top of the valve guard plate 1. A second drive assembly 9 is rotatably connected to the inner wall of the protective plate 8. A second passive assembly 10 is rotatably connected to the top of the inner cavity of the protective plate 8. The second passive assembly 10 includes a second rotating rod 28. A cross plate 30 is fixedly connected to the bottom of the second rotating rod 28. The inner surface of the cross groove is adapted to the outer surface of the cross plate 30. The second passive assembly 10 is connected to the second drive assembly 9 in a transmission manner. The ball core 2 is installed inside the valve guard plate 1 through the first passive assembly 6 and the second passive assembly 10.

[0030] In this embodiment, before the user screws the valve guard plate 1 and the base 4 into place, the user needs to apply an upward pulling force to the valve guard plate 1, so that the rotating disk 21, the push rod 22, and the support disk 23, which are at a fixed horizontal height, enter the interior of the mounting groove. During this process, the contractile property of the spring rod 24 can assist the sliding plate 25 in buffering the rotating disk 21, the push rod 22, and the support disk 23. Then, because the push rod 22 enters the mounting groove, there are no protruding structures inside the valve guard plate 1, allowing the user to quickly insert the ball core 2 into the interior of the valve guard plate 1. Then, the user can place the valve guard plate 1 downwards above the base 4. At this time, the push rod 22 will enter the opening of the ball core 2. At the cylindrical groove, the push rod 22 can then be used to fix the bottom of the ball core 2 in the horizontal and longitudinal directions. Then, the valve guard plate 1 and the base 4 are screwed on and installed. Then, the cross plate 30 is inserted into the cross groove opened in the ball core 2, so that the equipment can fix the top of the ball core 2 in the horizontal and longitudinal directions. Then, the valve guard plate 1 and the protective plate 8 are screwed on and installed. This upper and lower fixing method ensures that the ball core 2 can withstand the impact force, thereby preventing the ball core 2 from deviating and getting stuck. Then, the limiting rod 15 and the sealing ring 16 are inserted into the limiting groove and the first sealing groove opened on both sides of the valve guard plate 1. Then, the side guard plate 11 is fixed to both sides of the valve guard plate 1 with bolts, so that the two sides of the ball core 2 can be fixed again.

[0031] It should be noted that the second sealing groove and the installation of the sealing ring are to ensure the sealing of the bottom of the ball core 2, thereby preventing liquid from leaking out from the bottom of the ball core 2.

[0032] Example 2

[0033] like Figures 1-6 The image shows a second embodiment of the present invention, which differs from the first embodiment in that:

[0034] Compared to Embodiment 1, the first drive assembly 5 includes a first drive handle 17, with a first bevel gear 18 fixedly connected to the outer surface of the first drive handle 17 near the first passive assembly 6. A second bevel gear 20 is fixedly connected to the outer surface of the first rotating rod 19 located in the inner cavity of the base 4. The outer surface of the second bevel gear 20 meshes with the outer surface of the first bevel gear 18, and the ratio of the number of teeth on the surface of the second bevel gear 20 to the number of teeth on the surface of the first bevel gear 18 is three to one. The second drive assembly 9 includes a second drive handle 26, with a third bevel gear 27 fixedly connected to the outer surface of the second drive handle 26 near the second passive assembly 10. The number of teeth on the surface of the third bevel gear 27 is equal to the number of teeth on the surface of the first bevel gear 18. A fourth bevel gear 29 is fixedly connected to the outer surface of the second rotating rod 28. The outer surface of the fourth bevel gear 29 meshes with the outer surface of the third bevel gear 27, and the number of teeth on the surface of the fourth bevel gear 29 is equal to the number of teeth on the surface of the second bevel gear 20.

[0035] In this embodiment, when the user applies a rotational force to the second drive handle 26, the third bevel gear 27 drives the fourth bevel gear 29 to rotate, which in turn causes the second rotating rod 28 to rotate with the cross plate 30, thereby generating a rotational force on the top of the ball core 2. When the user applies a rotational force to the first drive handle 17, the first bevel gear 18 drives the second bevel gear 20 to rotate, which in turn causes the first rotating rod 19 to rotate with the rotating disk 21. Because the push rod 22 connected to the rotating disk 21 is inserted into the ball core 2, when the rotating disk 21 rotates, the push rod 22 generates a rotational force on the bottom of the ball core 2. Thus, by applying rotational force from top to bottom, the ball core 2 is prevented from getting stuck.

[0036] It should be noted that because the ratio of the number of teeth on the surface of the second bevel gear 20 to the number of teeth on the surface of the first bevel gear 18 is three to one, the user only needs to apply a small force to the first drive handle 17 to drive the second bevel gear 20 to rotate. Furthermore, because the number of teeth on the surface of the fourth bevel gear 29 is equal to the number of teeth on the surface of the second bevel gear 20, and the number of teeth on the surface of the third bevel gear 27 is equal to the number of teeth on the surface of the first bevel gear 18, the user only needs to apply a small force to the second drive handle 26 to drive the fourth bevel gear 29 to rotate.

[0037] Example 3

[0038] like Figures 5-6 The following is a third embodiment of the present invention, which differs from the first and second embodiments in that:

[0039] Compared to Embodiments 1 and 2, the front end of the further side guard plate 11 is fixedly connected to an electronic controller 12, an insulating ring 13 is fixedly connected inside the side guard plate 11, a magnetic suction plate 14 is fixedly connected inside the insulating ring 13, and the output line of the electronic controller 12 is connected to the magnetic suction plate 14.

[0040] In this embodiment, the electronic controller 12 is operated so that the magnetic suction plate 14 generates a magnetic force on the flow channel inside the side guard plate 11, thereby causing the magnetic suction plate 14 to adsorb impurities in the liquid inside the side guard plate 11, thereby preventing impurities from entering the gap between the ball core 2 and the valve guard plate 1, and thus preventing the ball core 2 from getting stuck due to the accumulation of impurities.

[0041] It should be noted that the insulating ring 13 can insulate the current output by the electronic controller 12 to the magnetic plate 14, thereby preventing the current from coming into contact with the liquid inside the side guard plate 11 and eliminating safety hazards.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
