Description

Technical Field

[0001] This invention relates to the field of ball valves, specifically to a top-mounted ball valve that facilitates the assembly and disassembly of the ball. Background Technology

[0002] Top-entry ball valves are rotary on / off valves that control the flow of media by rotating a ball. A 90-degree rotation of the ball allows the media to pass through or close the passage within the ball, thus controlling the media flow. These valves offer advantages such as compact structure, good sealing performance, reliable operation, and easy maintenance. They are widely used in oil and gas pipelines, as well as in oil extraction, refining, petrochemical, chemical, chemical fiber, metallurgical, power, nuclear power, food, and papermaking plants. They are particularly suitable for media control in high-pressure, high-temperature environments, such as in oil refining, chemical, power, and pharmaceutical industries. In industrial pipeline systems, a welded connection between the valve body and the pipes at both ends is a common practice, enhancing the system's sealing and robustness.

[0003] However, in cases where emergency repairs or replacements of ball valves are required, it is usually necessary to cut the ball valve from the pipeline. This process is not only complicated but may also damage the ball valve and the pipeline. Due to the difficulty of disassembly, it may take longer to complete the repair work, which will lead to production line interruption, reduced production efficiency, and may affect the overall economic benefits of the enterprise. Furthermore, the disassembly process may cause damage to the ball valve and the pipeline, resulting in a waste of resources. Therefore, we propose a top-mounted ball valve that is easy to disassemble and assemble. Summary of the Invention

[0010] Preferably, the closing device further includes a fixed base, a support spring, and a support cylinder. Two fixed bases are provided. The bottoms of the two fixed bases are fixedly connected to the top of the fixed plate, the tops of the two fixed bases are fixedly connected to the bottom of the support spring, the top of the support spring is fixedly connected to the bottom of the support cylinder, the top of the support cylinder is fixedly connected to the bottom of the support plate, and the bottom of the support cylinder is slidably connected to the tops of the two fixed bases.

[0011] Preferably, the closing device further includes a first linkage rod, a support block, teeth, a fixed shaft, and a second linkage rod. Multiple first linkage rods are distributed at both ends and sides of the two fixed bases. The bottoms of the multiple first linkage rods are rotatably connected to the two fixed bases via connecting rods. The tops of the multiple first linkage rods are rotatably connected to the bottom of the support block via connecting rods. The top of the support block is fixedly connected to the bottom of the teeth, and the top of the teeth is fitted against the inner wall of the fixed membrane.

[0012] Preferably, the pushing assembly includes a mounting plate, a linkage spring, a movable plate, and a positioning rod.

[0013] Preferably, a sealing strip is fixedly connected to the inner wall of the fitting ring, and a hanging plate is fixedly connected to the end of the fitting ring near the valve ball, the hanging plate being arc-shaped.

[0014] Compared with the prior art, the present invention provides a top-mounted ball valve that facilitates the assembly and disassembly of the ball, and has the following beneficial effects: 1. This top-mounted ball valve, which facilitates the assembly and disassembly of the ball, is installed by first pushing the valve ball into the housing through the mounting cylinder. Then, the linkage groove is connected to the directional control rod. The valve ball is then pressed against the sealing ring by applying a thrust. While the sealing ring is being pressed, the positioning rod in the assembly slides inside the mounting plate. The spring force generated by the linkage spring then pushes the valve ball to clamp it, making the sealing strip inside the sealing ring fit tightly against the outer surface of the valve ball, thus providing a better seal when closed.

[0015] 2. This top-mounted ball valve, which is easy to assemble and disassemble, can be used by turning a wrench. The wrench drives the directional control lever to rotate through the directional conversion connector. When the directional control lever rotates, the valve ball rotates through the connection with the linkage groove. When the valve ball rotates, the outer wall of the valve ball is scraped and cleaned through the linkage groove inside the fitting ring, so that it can be cleaned during use.

[0016] 3. This top-mounted ball valve, which is easy to install and disassemble, allows for easy installation by holding the control groove at the bottom of the fixing plate in the closing device, and then pushing the support plate through the fixing base, support spring, and support cylinder. The fitting groove inside the support plate fits against the bottom of the valve ball, thus supporting the bottom of the valve ball. While pushing the fixing plate, the fixing strip on the outside of the support plate and the outer wall of the fixing plate fit against the inside of the mounting cylinder, and the friction force is used to quickly fix the valve.

[0017] 4. This top-mounted ball valve, which facilitates the assembly and disassembly of the ball, works as follows: During installation, pushing the fixed plate compresses the support spring, shortening the distance between the support plate and the fixed plate. This causes one end of the second linkage rod to rotate via the fixed shaft, while the other end pushes the first linkage rod downwards. Simultaneously, the second linkage rod slides inside the first linkage rod. When the first linkage rod is under force, it causes the support block to approach the fixed diaphragm. The support block supports the fixed diaphragm through its teeth. As the fixed diaphragm is supported, its outer wall adheres to the inner wall of the mounting cylinder, increasing friction and enhancing its fixing effect.

[0018] 5. This top-mounted ball valve, which facilitates easy assembly and disassembly of the ball, allows for quick fixation of the ball by contacting the bottom of the valve ball with the support plate in the closure device. During disassembly, the closure device can be quickly removed by pulling the control groove, followed by the removal of the valve ball. This simplifies and speeds up the maintenance process, reduces production line downtime, improves production efficiency, enhances the overall economic benefits of the enterprise, and reduces economic losses caused by maintenance. By reducing destructive operations such as cutting and welding, it saves on the cost of replacing damaged parts, reduces resource waste, and minimizes the impact on the overall structure and strength of the pipeline system.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-9 A top-mounted ball valve with an easily detachable ball, comprising a housing 1, an mounting sleeve 29 at the bottom of the housing 1, a valve ball 5 disposed inside the housing 1, and further comprising: Direction conversion connector 2, located on the top of housing 1, is used to control the movement of valve ball 5; A closing device is installed inside the mounting cylinder 29 for quick installation and removal of the valve ball 5; Fitting rings 24 are provided at both ends of the valve ball 5 to facilitate sealing of both ends of the valve ball 5; The push assembly, located at both ends of the fitting ring 24, is used to push the fitting ring 24 to fit with the valve ball 5. The maintenance process will become simpler and faster, reducing production line downtime, improving production efficiency, enhancing the overall economic benefits of the enterprise, and reducing economic losses caused by maintenance. Since destructive operations such as cutting and welding are reduced, the cost of replacing damaged parts can be saved, and resource waste can be reduced. It can also reduce the impact on the overall structure and strength of the pipeline system.

[0023] Furthermore, the bottom of the direction conversion connector 2 is fixedly connected to the top of the housing 1. A rotating wrench 3 is hinged to one side of the direction conversion connector 2. The bottom output end of the direction conversion connector 2 extends into the housing 1 and is fixedly connected to the top of the direction control lever 4. When needed, the rotating wrench 3 is rotated, which drives the direction control lever 4 to rotate through the direction conversion connector 2. When the direction control lever 4 rotates, the valve ball 5 rotates through the connection with the linkage groove 6. When the valve ball 5 rotates, the outer wall of the valve ball 5 is scraped and cleaned through the linkage groove 6 inside the fitting ring 24, so that it can be cleaned during use.

[0024] Furthermore, the bottom of the directional control lever 4 is flat, the top of the valve ball 5 is provided with a linkage groove 6 corresponding to the directional control lever 4, the center of the valve ball 5 is provided with a through hole, and the bottom of the directional control lever 4 is movably connected to the inside of the linkage groove 6.

[0025] Furthermore, the closing device includes a support plate 7, a fixing strip 8, a fixing plate 9, a control groove 10, a fixing membrane 11, a connecting plate 27, and a fitting groove 28. The fitting groove 28 is located on the top of the support plate 7, corresponding to the valve ball 5. The outer wall of the support plate 7 is fixedly connected to the fixing strip 8. The bottom of the support plate 7 is fixedly connected to the top of the fixing membrane 11, and the bottom of the fixing membrane 11 is fixedly connected to the top of the fixing plate 9. The control groove 10 is located on the bottom of the fixing plate 9 and is trapezoidal in shape. The top of the connecting plate 27 is fixedly connected to the bottom of the fixing plate 9. By holding the control groove 10 located on the bottom of the fixing plate 9 in the closing device, the support plate 7 is pushed by the fixing base 12, the support spring 13, and the support cylinder 14. The fitting groove 28 inside the support plate 7 fits against the bottom of the valve ball 5, thus supporting the bottom of the valve ball 5. While the fixed plate 9 is being fixed, the fixing strip 8 on the outside of the support plate 7 and the outer wall of the fixed plate 9 are respectively attached to the inside of the mounting cylinder 29 and fixed by friction. Then, when the fixed plate 9 is pushed, the support spring 13 is squeezed, which shortens the distance between the support plate 7 and the fixed plate 9, causing one end of the second linkage rod 19 to rotate through the fixed shaft 18. The other end of the second linkage rod 19 pushes the first linkage rod 15 downward. While pushing the first linkage rod 15, the second linkage rod 19 slides inside the first linkage rod 15. When the first linkage rod 15 is subjected to force, it drives the support block 16 to approach the fixed membrane 11. The support block 16 supports the fixed membrane 11 through the teeth 17. When the fixed membrane 11 is supported, the outer wall of the fixed membrane 11 is attached to the inner wall of the mounting cylinder 29 to increase friction and enhance its fixing effect.

[0026] Furthermore, the fixing strip 8 and the fixing film 11 are made of rubber, and the outer walls of the fixing strip 8 and the fixing film 11 are respectively attached to the inner wall of the mounting cylinder 29, and the outer wall of the fixing plate 9 is attached to the inner wall of the mounting cylinder 29.

[0027] Furthermore, the closing device also includes a fixed base 12, a support spring 13, and a support cylinder 14. There are two fixed bases 12. The bottoms of the two fixed bases 12 are fixedly connected to the top of the fixed plate 9, the tops of the two fixed bases 12 are fixedly connected to the bottom of the support spring 13, the top of the support spring 13 is fixedly connected to the bottom of the support cylinder 14, the top of the support cylinder 14 is fixedly connected to the bottom of the support plate 7, and the bottom of the support cylinder 14 is slidably connected to the tops of the two fixed bases 12.

[0028] Furthermore, the closing device also includes a first linkage rod 15, a support block 16, teeth 17, a fixed shaft 18, and a second linkage rod 19. Multiple first linkage rods 15 are respectively distributed at both ends and sides of the two fixed bases 12. The bottoms of the multiple first linkage rods 15 are rotatably connected to the two fixed bases 12 via connecting rods. The tops of the multiple first linkage rods 15 are rotatably connected to the bottom of the support block 16 via connecting rods. The top of the support block 16 is fixedly connected to the bottom of the teeth 17. The top of the teeth 17 is attached to the inner wall of the fixed membrane 11. The bottoms of the second linkage rods 19 are slidably connected to the interior of the multiple first linkage rods 15 via connecting rods. The tops of the second linkage rods 19 are rotatably connected to the fixed shaft 18 via connecting rods. The top of the fixed shaft 18 is fixedly connected to the inner wall of the support plate 7.

[0029] Furthermore, the pushing component includes a mounting plate 20, a linkage spring 21, a movable plate 22, and a positioning rod 23. Multiple mounting plates 20 are provided and arranged around the fitting ring 24. One end of each mounting plate 20 is slidably connected to the movable plate 22. The linkage spring 21 is fixedly connected between the multiple mounting plates 20 and the movable plate 22. The positioning rod 23 is fixedly connected to both ends of the multiple mounting plates 20 and the positioning rod 23. The other end of each mounting plate 20 is fixedly connected to the inner wall of the outer casing 1 via the positioning rod 23. The end of the positioning rod 23 away from the linkage spring 21... The positioning rod 23 is fixedly connected to the fitting ring 24. During installation, the valve ball 5 is first pushed into the housing 1 through the mounting cylinder 29. Then, the linkage groove 6 is connected to the direction control rod 4. Then, the fitting ring 24 is squeezed by the pushing force applied to the valve ball 5. When the fitting ring 24 is squeezed, the positioning rod 23 in the push assembly slides inside the mounting plate 20. Then, the elastic force generated by the linkage spring 21 pushes the valve ball 5 to clamp it, so that the sealing strip 25 inside the fitting ring 24 is tightly fitted to the outer surface of the valve ball 5, so that it can better seal when closed.

[0030] Furthermore, a sealing strip 25 is fixedly connected to the inner wall of the fitting ring 24, and a hanging plate 26 is fixedly connected to one end of the fitting ring 24 near the valve ball 5. The hanging plate 26 is arc-shaped.

[0031] Working principle: During installation, the valve ball 5 is first pushed into the housing 1 through the mounting cylinder 29. Then, the linkage groove 6 is connected to the direction control rod 4. The pushing force applied to the valve ball 5 compresses the fitting ring 24. While compressing the fitting ring 24, the positioning rod 23 in the push assembly slides inside the mounting plate 20. Then, the elastic force generated by the linkage spring 21 pushes the valve ball 5 to clamp it, so that the sealing strip 25 inside the fitting ring 24 is tightly fitted to the outer surface of the valve ball 5, so that it can better seal when closed. After the fitting ring 24 clamps the valve ball 5, the fixing plate 9 in the hand-held closing device is used to close the device. The control groove 10 is opened at the bottom, and then the support plate 7 is pushed by the fixed base 12, the support spring 13, and the support cylinder 14. The fitting groove 28 inside the support plate 7 fits with the bottom of the valve ball 5, so that it supports the bottom of the valve ball 5. At the same time as pushing the fixed plate 9, the fixing strip 8 on the outside of the support plate 7 and the outer wall of the fixed plate 9 respectively fit with the inside of the mounting cylinder 29, and are fixed by friction. Then, when the fixed plate 9 is pushed, the support spring 13 is squeezed, and the distance between the support plate 7 and the fixed plate 9 is shortened, so that one end of the second linkage rod 19 rotates through the fixed shaft 18. The other end of the linkage rod 19 pushes the first linkage rod 15 downwards. Simultaneously, the second linkage rod 19 slides inside the first linkage rod 15. When the first linkage rod 15 is subjected to force, it causes the support block 16 to approach the fixing membrane 11. The support block 16 supports the fixing membrane 11 through the teeth 17. During this support, the outer wall of the fixing membrane 11 adheres to the inner wall of the mounting cylinder 29, increasing friction and enhancing its fixing effect. When needed, the rotation wrench 3 is turned, and the rotation wrench 3 controls the direction via the direction conversion connector 2. When lever 4 rotates, the valve ball 5 rotates through its connection with the linkage groove 6. As the valve ball 5 rotates, the linkage groove 6 inside the fitting ring 24 scrapes and cleans the outer wall of the valve ball 5, making it easier and faster to maintain during use. This reduces production line downtime, improves production efficiency, enhances the overall economic benefits of the enterprise, and reduces economic losses caused by maintenance. By reducing destructive operations such as cutting and welding, the cost of replacing damaged parts can be saved, resource waste can be reduced, and the impact on the overall structure and strength of the pipeline system can be reduced.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
