[0002] Valves are control components in fluid delivery systems, with functions such as diversion, interception, regulation, throttling, backflow prevention, diversion or overflow pressure relief. Anti-leakage valves are valves designed to prevent media leakage. They are commonly used in chemical, petroleum, natural gas and other industries. Especially when dealing with harmful, corrosive or high-pressure fluids, anti-leakage valves can ensure the safe operation of the system.

[0003] The traditional anti-leakage valve is composed of a valve body, a valve cover, an anti-leakage mechanism and other parts.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Refer to Figures 1 - 3 , an embodiment provided by the present invention: a leak-proof valve, including a valve body 1, a first fixing sleeve 2 is fixedly connected to the side wall of the valve body 1, a connecting pipe 3 is arranged on the side wall of the first fixing sleeve 2, a second fixing sleeve 4 is fixedly connected to the side wall of the connecting pipe 3, a first clamping strip 5 is fixedly connected to the side wall of the second fixing sleeve 4, a first clamping block 6 is fixedly connected to the side wall of the second fixing sleeve 4, the side wall of the first clamping strip 5 is in contact with the side wall of the first clamping block 6, a second clamping strip 7 is fixedly connected to the side wall of the first fixing sleeve 2, a second clamping block 8 is fixedly connected to the side wall of the first fixing sleeve 2, the side wall of the second clamping strip 7 is in contact with the side wall of the second clamping block 8, a third clamping block 9 is fixedly connected to the side wall of the first fixing sleeve 2, a third sealing ring 27 is arranged inside the first fixing sleeve 2, a first clamping groove 10 is opened inside the second fixing sleeve 4, and the side wall of the third clamping block 9 is slidably connected inside the first clamping groove 10. An auxiliary component is arranged inside the valve body 1 to prevent liquid leakage. A valve cover 11 is arranged on the upper surface of the valve body 1. The auxiliary component includes a first sealing ring 16, and the side wall of the first sealing ring 16 is fixedly connected inside the valve body 1. A cylindrical sleeve 12 is fixedly connected to the upper surface of the valve cover 11. A threaded column 13 is threadedly connected inside the cylindrical sleeve 12. One end of the threaded column 13 is fixedly connected to a rotating handle 14, and the other end of the threaded column 13 is fixedly connected to a gate valve 15. The side wall of the gate valve 15 is slidably connected inside the valve body 1, and the side wall of the gate valve 15 is in contact with the first sealing ring 16. The side wall of the first clamping block 6 is engaged with the side wall of the second clamping strip 7, and the side wall of the second clamping block 8 is engaged with the side wall of the first clamping strip 5;

[0035] When using this device, when it is necessary to connect to a pipeline, the connecting pipe 3 can be rotated so that the first clamping strip 5 will engage with the second clamping block 8, and the second clamping strip 7 will also engage with the first clamping block 6. At the same time, due to the fitting of the second fixing sleeve 4 and the first fixing sleeve 2, the third clamping block 9 will slide into the first clamping groove 10. While rotating the connecting pipe 3, the third clamping block 9 slides along the groove of the first clamping groove 10. Since the third clamping block 9 is T-shaped, it is stuck inside the first clamping groove 10 during sliding. A third sealing ring 27 is provided inside the first fixing sleeve 2, which can improve the sealing performance between the pipeline and the valve. Through this clamping method, the rapid installation and disassembly of the device can be easily achieved. Through this design that is convenient for installation and disassembly, the maintenance time can be significantly shortened, the operation efficiency of the pipeline system can be improved, when the valve needs to be replaced or repaired, the operation can be carried out quickly, the system downtime can be reduced, and the continuous and stable operation of the pipeline system can be ensured. It can more easily adapt to different working environments and conditions, improving the applicability and flexibility of the valve. By providing the third clamping block 9 inside the first fixing sleeve 2 and the second fixing sleeve 4, the small gaps at the connection between the valve and the pipeline can be effectively filled, preventing fluid leakage and ensuring the sealing of the pipeline system. A first sealing ring 16 is provided inside the valve body 1, which has good sealing performance and can reduce the wear of the valve, thereby extending its service life.

[0036] Referring to Figures 4 - 5 , a second clamping groove 19 is formed inside the valve body 1. A second sealing ring 17 is provided between the valve body 1 and the valve cover 11. A cylindrical shell 18 is provided inside the valve cover 11. A sliding column 20 is slidably connected inside the cylindrical shell 18. A rotating column 21 is rotatably connected inside the sliding column 20. A pull handle 22 is fixedly connected to the upper surface of the rotating column 21. A fixing ring 24 is fixedly connected to the side wall of the sliding column 20. A spring 23 is sleeved on the side wall of the sliding column 20. One end of the spring 23 is fixedly connected inside the cylindrical shell 18, and the other end of the spring 23 is fixedly connected to the side wall of the fixing ring 24. A fixing column 25 is fixedly connected to the lower surface of the rotating column 21. A fixing block 26 is fixedly connected to the side wall of the fixing column 25. The side wall of the fixing block 26 is slidably connected inside the second clamping groove 19, and the side wall of the fixing block 26 is slidably connected inside the cylindrical shell 18.

[0037] By closely fitting the valve cover 11 with the upper surface of the valve body 1, and then rotating the pull handle 22 by 90 degrees, this action will drive the rotating column 21 to rotate accordingly, thereby causing the spring 23 to lose the squeezed state, and the spring 23 can rebound. The resilience of the spring 23 pushes the fixed column 25 to move downward, causing the fixed block 26 to disengage from the inside of the cylindrical shell 18. Subsequently, the fixed block 26 slides into the inside of the second slot 19. Next, perform a 90-degree rotation operation again and pull the pull handle 22. This time, it is to drive the fixed column 25 to rotate. Through such rotation, the fixed block 26 is stuck inside the second slot 19, thus achieving the fixing effect. In this way, the second sealing ring 17 can fit more closely at the connection of the valve body 1, which can effectively prevent the leakage of the medium, ensure the sealing performance of the valve and the normal operation of the equipment. This design helps to improve the overall sealing performance and prevent resource waste and environmental pollution.

[0038] Working principle: When using this equipment for work, rotate the rotating handle 14 to rotate the threaded column 13, thereby driving the gate valve 15 to move downward to block the liquid inside the valve body 1. When it is necessary to connect the valve to the pipeline, rotate the connecting pipe 3 to make the first clamping strip 5 engage with the second clamping block 8, and at the same time make the second clamping strip 7 engage with the first clamping block 6, so as to achieve the effect of quick installation and disassembly. By fitting the valve cover 11 with the upper surface of the valve body 1, and then rotating the pull handle 22 by 90 degrees to drive the rotating column 21 to rotate, the spring 23 loses the extrusion and rebounds, thereby pushing the fixed column 25 to move downward, causing the fixed block 26 to disengage from the inside of the cylindrical shell 18 and slide into the inside of the second slot 19. Then rotate the pull handle 22 by 90 degrees again to drive the fixed column 25 to rotate, thereby clamping the fixed block 26 inside the second slot 19 to achieve the fixing effect, and making the second sealing ring 17 fit more closely at the connection of the valve body 1 to achieve a good anti-leakage effect.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
