Description

Technical Field

[0001] This utility model relates to the field of valves, specifically a high-performance butyl rubber gasket valve that prevents air leakage. Background Technology

[0002] Butyl rubber gasket valves are valve body devices used in tires. Their main function is to allow gas to enter the tire or inner tube and automatically close and seal to retain the gas after it is full of gas, thereby generating air pressure and preventing gas from escaping. Butyl rubber gasket valves are usually made of butyl rubber, which has good airtightness and aging resistance, and can effectively extend the service life of the valve.

[0003] Existing butyl rubber gasket valves only have one leak-proof structure, which can only prevent gas inside the tire from leaking out of the venting pipe. In actual use, the seal between the metal venting pipe on the valve and the valve body made of butyl rubber material is poor, and gas inside the tire can easily leak out from the gap between the venting pipe and the valve body, resulting in poor valve sealing. To address this problem, a high-performance butyl rubber gasket valve that prevents leaks is now provided. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model discloses a high-performance butyl rubber gasket valve that prevents air leakage. By setting a first sealing mechanism, it can seal the air passage. By setting a second sealing mechanism, it can seal the air outlet. This can further prevent the air inside the tire from leaking from the connection between the air passage and the valve body, thus playing a double sealing role.

[0019] 3. This utility model provides a high-performance butyl rubber gasket valve that prevents air leakage. When air is inflated into the valve body, the sealing plate moves away from the hollow tube, allowing gas to enter the valve body. When the gas inside the valve body reaches a certain pressure, it pushes the sealing fastener to move, enabling the gas inside the valve body to enter the tire through the outlet pipe, thus achieving inflation. After inflation is complete, both the sealing fastener and the sealing plate automatically close, sealing the tire and preventing the gas inside from flowing out in reverse.

[0027] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0028] The present invention provides the following preferred embodiments:

[0029] Example 1, as Figures 1-6 As shown, a high-performance butyl rubber gasket valve with leak-proof design includes a valve body 11, an air passage 12, an air outlet 20, an air outlet pipe 21, a first sealing mechanism, and a second sealing mechanism. The air passage 12 is inserted into the top of the valve body 11. Specifically, the air passage 12 is fixedly connected to the valve body 11. The air outlet 20 is located at the bottom of the valve body 11. The air outlet pipe 21 is inserted into the air outlet 20. Specifically, the air outlet pipe 21 and the air outlet 20 are fixedly connected. The first sealing mechanism is installed inside the air passage 12, and the second sealing mechanism is installed on the air outlet pipe 21.

[0030] The first sealing mechanism includes a hollow tube 13, a sealing plate 18, and a telescopic assembly. The hollow tube 13 is inserted into the inner wall of the ventilation pipe 12, and the ventilation pipe 12 and the hollow tube 13 are fixedly connected. The sealing plate 18 is located at the bottom end of the hollow tube 13, and the top end of the sealing plate 18 abuts against the bottom end of the hollow tube 13. The telescopic assembly is located between the sealing plate 18 and the hollow tube 13.

[0031] The telescopic assembly is used to move the sealing plate 18. When the sealing plate 18 moves downward, it moves away from the hollow tube 13, and gas can flow out from the gap between the hollow tube 13 and the sealing plate 18 to achieve inflation. When the sealing plate 18 moves to fit with the hollow tube 13, it can seal the bottom end of the hollow tube 13, so that the gas inside the valve body 11 cannot flow to the outside from the connection between the hollow tube 13 and the sealing plate 18.

[0032] The second sealing mechanism includes a conical groove 22, a sealing block 23, a sealing component, and a moving component. The conical groove 22 is formed on the inner wall of the end of the vent pipe 21 away from the ventilation pipe 12. The sealing block 23 is located inside the vent pipe 21. The outer wall of the sealing block 23 contacts the inner wall of the conical groove 22. The shape of the sealing block 23 matches the shape of the conical groove 22. The moving component is located between the sealing block 23 and the vent pipe 21. The sealing component is located between the vent pipe 21 and the valve body 11.

[0033] The moving component is used to move the sealing block 23. When the valve body 11 is inflated, the sealing plate 18 moves away from the hollow tube 13, and the gas can enter the valve body 11. When the gas inside the valve body 11 reaches a certain pressure, the gas inside the valve body 11 can push the sealing block 23 to move through the moving component, so that the gas inside the valve body 11 can enter the tire through the outlet pipe 21 to achieve inflation. At the same time, after inflation is completed, the sealing block 23 and the sealing plate 18 are automatically closed to achieve sealing, so that the gas inside the tire cannot flow out in reverse.

[0034] like Figures 1-6 As shown, the telescopic assembly includes a retaining ring 16, a first spring 17, and a valve stem 19. The retaining ring 16 is fixedly installed on the inner wall of the hollow tube 13. The valve stem 19 is located in the middle of the retaining ring 16. The bottom end of the valve stem 19 is fixedly connected to the sealing plate 18. The first spring 17 is sleeved on the outside of the valve stem 19. The two ends of the first spring 17 are respectively connected to the retaining ring 16 and the sealing plate 18.

[0035] In the initial state, the top surface of the sealing plate 18 is in contact with the bottom surface of the hollow tube 13, and the first spring 17 is in a stretched but not fully stretched state. By using the first spring 17, the sealing plate 18 can always have a force that moves towards the hollow tube 13, thereby increasing the sealing between the sealing plate 18 and the hollow tube 13.

[0036] When the air vent 12 is filled with air, the air pump will drive the valve stem 19 to move downwards, and the valve stem 19 will drive the sealing plate 18 to move downwards. At this time, the first spring 17 is stretched again, and the gas can pass through the gap between the fixed ring 16 and the valve stem 19 and flow out from the bottom end of the hollow tube 13 to the inside of the valve body 11.

[0037] like Figures 1-6 As shown, a limiting ring 14 is provided at the top of the inner cavity of the hollow tube 13. A connecting rod 15 is fixed at equal intervals on the outer side of the limiting ring 14. The other end of the connecting rod 15 is fixedly connected to the hollow tube 13. The valve stem 19 is slidably disposed inside the limiting ring 14. The limiting ring 14 can guide the valve stem 19.

[0038] like Figures 1-6 As shown, the moving assembly includes multiple fixed plates 24, multiple second springs 26, and multiple guide rods 25. The multiple fixed plates 24 are equidistantly installed on the inner wall of the top end of the air outlet pipe 21. Each guide rod 25 is slidably disposed inside a fixed plate 24. The bottom end of each guide rod 25 is fixedly connected to the sealing block 23. Each second spring 26 is sleeved on a guide rod 25. Both ends of each second spring 26 are respectively connected to the sealing block 23 and the fixed plate 24.

[0039] In the initial state, the outer wall of the sealing block 23 is in close contact with the inner wall of the conical groove 22, and the second spring 26 is in a stretched but not fully stretched state. When the gas inside the valve body 11 reaches a certain pressure, the gas inside the valve body 11 can push the sealing block 23 to move. The sealing block 23 drives the guide rod 25 to slide on the fixed plate 24, and the second spring 26 is stretched. When the sealing block 23 moves, it does not contact the conical groove 22, and a channel for gas to pass through is formed between the conical groove 22 and the sealing block 23, so that the gas inside the valve body 11 can enter the interior of the tire through the air outlet pipe 21 to achieve inflation.

[0040] like Figures 1-6 As shown, the sealing assembly includes a groove 27, a connecting plate 29, and a sealing ring 28. The connecting plate 29 is fixedly sleeved on the outside of the air outlet pipe 21. The groove 27 is opened at the bottom end of the valve body 11. The sealing ring 28 is inserted into the inside of the groove 27, and the bottom end of the sealing ring 28 is fixedly connected to the connecting plate 29. When the air outlet pipe 21 is fixedly installed inside the air outlet 20, the sealing ring 28 can be inserted into the inside of the groove 27. Through the groove 27 and the sealing ring 28, the sealing effect between the air outlet pipe 21 and the valve body 11 can be increased, the possibility of gas leakage from the gap between the air outlet pipe 21 and the valve body 11 can be reduced, and the overall sealing effect of the valve can be further improved.

[0041] like Figures 1-6 As shown, a first protrusion 30 and a second protrusion 31 are fixed on the outer side of the valve body 11. The first protrusion 30 and the second protrusion 31 are arranged vertically, and an installation groove 32 is formed between the first protrusion 30 and the second protrusion 31. The valve body can be installed on the wheel hub using the installation groove 32. At the same time, the first protrusion 30 and the second protrusion 31 on both sides can fit tightly against the inner and outer surfaces of the wheel hub to achieve a sealing effect.

[0042] like Figures 1-6 As shown, a through hole is formed between two adjacent connecting rods 15 to facilitate the passage of gas and enable tire inflation.

[0043] like Figures 1-6 As shown, the vent pipe 12, hollow pipe 13 and fixing ring 16 are integrally formed, which can increase the overall strength of the valve and improve its service life.

[0044] The beneficial effects of this utility model are specifically reflected in the fact that the above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
