Description

Technical Field

[0001] This utility model relates to the field of maintenance device technology, specifically to a quick disassembly and maintenance device for a track ball valve core. Background Technology

[0002] In industries such as petroleum, chemical, and natural gas, ball valves are widely used as key fluid control devices due to their excellent sealing performance and low operating torque. However, after long-term operation, the valve core, a core component of this type of valve, is prone to damage or sealing failure due to media erosion, corrosion, or solid particle accumulation, requiring regular maintenance or replacement.

[0003] Traditional valve core disassembly methods primarily rely on manual labor, such as striking with a sledgehammer, prying with a crowbar, or pushing with simple tools. These methods are not only inefficient and extremely labor-intensive but also pose significant safety risks. Rough handling can easily cause irreversible damage to the delicate valve seat sealing surface and valve core surface coating, and may even lead to stripped valve body threads or component breakage, resulting in larger equipment accidents and high maintenance costs. Current technology lacks a dedicated disassembly device that integrates multiple functions, is safe and efficient, and causes no damage to the equipment. This has resulted in on-site maintenance work facing a long-standing dilemma of being time-consuming, labor-intensive, highly technically dependent, and having unreliable results.

[0004] Therefore, it is necessary to invent a quick disassembly and maintenance device for the core of a track ball valve to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a quick disassembly and maintenance device for a track ball valve core. By cooperating with the main support and the side rod, the efficiency is improved, thereby solving the problem that the existing technology lacks a dedicated disassembly device that integrates multiple functions, is safe and efficient, and does not damage the equipment. This has led to the long-standing dilemma that on-site maintenance work is time-consuming, labor-intensive, highly dependent on technology, and difficult to guarantee results.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick disassembly and repair device for a track ball valve core, comprising a main support, wherein the main support has first adsorption grooves at both ends and magnets are fixedly connected to the inner side of the first adsorption grooves, a side rod is hinged inside the first adsorption groove, a first hexagonal part is fixedly connected to the outer side wall of the side rod, and the first hexagonal part connected to different side rods has a different model, a movable rod slides inside the main support, a second hexagonal part is fixedly connected to the top of the movable rod, the second hexagonal part has a different model than the first hexagonal part, and a conical extractor is fixedly connected to the bottom end of the movable rod. Through the cooperation of the main support and other parts, this structure can flexibly adapt to different types of bolts.

[0007] Preferably, a second adsorption groove is fixedly connected to the front side of the main support, a magnet is fixedly connected to the inner side of the second adsorption groove, and a rotating part is hinged inside the second adsorption groove to drive the movement of subsequent parts.

[0008] Preferably, one of the two sets of rotating parts is internally threaded with a threaded rod, and the other set of the two sets of rotating parts is slidably connected to a limiting frame at its bottom end, with the length of the limiting frame being adjusted by the threaded rod.

[0009] Preferably, the outer wall of the threaded rod is threaded with an adjusting bolt, which is rotatably connected to the top of the limiting frame. The surface of the limiting frame is provided with a snap-fit ​​groove, and the small ball valve is fixed by the cooperation between the limiting frame and the snap-fit ​​groove.

[0010] Preferably, the surface of the movable rod is provided with three sets of limiting grooves, and the surface of the main bracket is provided with a moving groove, which enables the movement of subsequent parts.

[0011] Preferably, a limiting rod is slidably connected inside the actuating groove, and an actuating rod is fixedly connected to the surface of the limiting rod, so as to drive the limiting rod to move.

[0012] Preferably, a limiting spring is fixedly connected to one side of the actuating rod, and the other side of the limiting spring is fixedly connected to the inner wall of the actuating groove. The limiting spring is sleeved on the outside of the limiting rod, and the cross-sectional size of the limiting rod is consistent with that of the limiting groove. The movable rod is limited by the cooperation between the limiting rod and the limiting groove.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows: The first and second adsorption tanks, along with the hinged side rod, modularly integrate various tools such as the first hexagonal part, the second hexagonal part, and the conical extractor, greatly enhancing the portability and ease of operation of the equipment. This effectively prevents the loss of tool parts. Its core advantage lies in the fact that the main support and the movable rod can serve as a multi-functional support base: when using the first hexagonal part at the end of the side rod to remove the valve cover bolts, or when the extension rod is fitted onto the second hexagonal part at the top of the movable rod to drive the conical extractor, the main support itself can be stably mounted on the valve body, providing a stable fulcrum for the side rod or the fitted extension rod. By cleverly utilizing the lever principle, the force applied by the operator is amplified, thereby significantly reducing the labor intensity of disassembly operations and achieving labor-saving operation.

Side rods 2 are hinged inside the first adsorption grooves 3. First hexagonal portions 4 are fixedly connected to the outer side walls of the side rods 2, and different types of first hexagonal portions 4 are connected to different side rods 2. A movable rod 5 slides inside the main support 1. A second hexagonal portion 6 is fixedly connected to the top of the movable rod 5. The second hexagonal portion 6 is of a different type than the first hexagonal portion 4. The bottom end of the movable rod 5 is fixedly... A conical extractor 11 is fixedly connected. Through the cooperation of the main support 1 and other parts, the structure can flexibly adapt to different types of bolts. A second adsorption groove 7 is fixedly connected to the front side of the main support 1. A magnet is fixedly connected to the inner side of the second adsorption groove 7. A rotating part 8 is hinged inside the second adsorption groove 7. The rotating part 8 drives the movement of subsequent parts. One of the two sets of rotating parts 8 is internally threaded with a threaded rod 15. The bottom end of the other set of rotating parts 8 is slidably connected with a limiting frame 9. The length of the limiting frame 9 is adjusted by the threaded rod 15.

[0019] Refer to the instruction manual appendix Figure 1-5An adjusting bolt 16 is threaded onto the outer wall of the threaded rod 15. The adjusting bolt 16 is rotatably connected to the top of the limiting frame 9. A snap-fit ​​groove 10 is provided on the surface of the limiting frame 9. The small ball valve is fixed by the cooperation between the limiting frame 9 and the snap-fit ​​groove 10. The surface of the movable rod 5 is provided with three sets of limiting grooves 12, and the surface of the main bracket 1 is provided with a moving groove 13. The moving groove 13 enables the movement of subsequent parts. A limiting rod 18 is slidably connected inside the moving groove 13. A moving rod 14 is fixedly connected to the surface of the limiting rod 18. The moving rod 14 drives the limiting rod 18 to move. A limiting spring 17 is fixedly connected to one side of the moving rod 14, and the other side of the limiting spring 17 is fixedly connected to the inner wall of the moving groove 13. The limiting spring 17 is sleeved on the outside of the limiting rod 18, and the cross-sectional size of the limiting rod 18 is the same as that of the limiting groove 12. The movable rod 5 is limited by the cooperation of the limiting rod 18 and the limiting groove 12. The first adsorption groove 3, the second adsorption groove 7 and the hinged side rod 2 are connected. The device modularly integrates various tools, including the first hexagonal part 4, the second hexagonal part 6, and the conical extractor 11, greatly enhancing the portability and ease of operation of the equipment and effectively preventing the loss of tool parts. Its core advantage lies in the fact that the main support 1 and the movable rod 5 can serve as a multi-functional support base: when using the first hexagonal part 4 at the end of the side rod 2 to remove the valve cover bolts, or when the lever is sleeved on the second hexagonal part 6 at the top of the movable rod 5 to drive the conical extractor 11, the main support 1 itself can be stably mounted on the valve body, providing a stable fulcrum for the side rod 2 or the sleeved lever. By cleverly utilizing the lever principle, the force applied by the operator is amplified, thereby significantly reducing the labor intensity of disassembly operations and achieving labor-saving operation.

[0020] The working principle of this practical application is as follows: Refer to the instruction manual appendix Figure 1-5 First, select the appropriate tools based on the operational requirements. If it is necessary to remove the valve cover bolts, flip the side rod 2 with the first hexagonal part 4 from the first adsorption groove 3 to stabilize the main support 1, making the side rod 2 a lever with the hinge point as the fulcrum. The operator can easily rotate the bolt by turning the far end of the side rod 2. If it is necessary to push out the valve core, attach the force rod to the second hexagonal part 6 at the top of the movable rod 5. At this time, the main support 1 serves as the base of the entire device, providing stable rotational support for the force rod. The operator turns the force rod with the main support 1 as the fulcrum, driving the movable rod 5 to move downward, thereby forcing the conical extractor 11 at the bottom to press or pull the valve core. During this process, by turning the toggle lever 14 to compress the limiting spring 17, the limiting rod 18 can be disengaged from the limiting groove 12, thereby adjusting the initial height of the movable rod 5. After the limiting rod 18 is reset, the stroke can be locked to ensure the stability and controllability of the operation process.
