Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a corrosion-resistant and durable butyl rubber gasket valve. Background Technology

[0002] Butyl rubber is a material with excellent airtightness, heat resistance, aging resistance, and chemical corrosion resistance. Using butyl rubber gaskets in valve stems ensures airtightness and prevents gas leakage. The aging resistance of butyl rubber gaskets allows them to maintain stable performance over a long period, extending the service life of the valve stem.

[0003] During the inflation and deflation process of butyl rubber gasket valves, specific tools are usually required to be inserted into the valve core for precise control of the valve core, thus ensuring smooth gas filling or release. However, in practice, if the operator is not equipped with the appropriate tools, or if the tools are incompatible, not only may the valve core fail to open or close effectively, but improper operation may also damage the valve core, potentially leading to gas leaks and other safety hazards.

[0004] Therefore, a corrosion-resistant and durable butyl rubber gasket valve needs to be designed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a corrosion-resistant and durable butyl rubber gasket valve.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A corrosion-resistant and durable butyl rubber gasket valve stem includes a valve stem tube, one end of which is provided with a butyl rubber gasket, and the other end of the valve stem tube away from the butyl rubber gasket is screwed with a valve cap. A valve core shell is fixedly installed on the inner wall of the valve stem tube, and a pressure rod is slidably installed on the inner wall of the valve core shell via a bracket. A sealing plate is fixedly installed at the bottom end of the pressure rod, and a second spring is fitted on the pressure rod. An operating mechanism is provided on the top surface of the valve cap, and a sealing mechanism is provided on the top surface of the valve core shell.

[0008] Preferably, the operating mechanism includes a push rod that passes through the top surface of the mouth cap, and the push rod is slidably connected to the through point. A pressure plate is fixedly installed at one end of the push rod located inside the mouth cap. A spring is fitted on the outer wall of the push rod located between the pressure plate and the mouth cap. An arc-shaped head is fixedly installed at one end of the push rod located outside the mouth cap.

[0009] Preferably, the outer wall of the pressure plate is in contact with the inner wall of the nozzle cap.

[0010] Preferably, the sealing mechanism includes a sealing cover fixedly installed on the top surface of the valve core housing, a sealing cavity one is provided on the upper inner side of the sealing cover, a sealing cavity two is provided on the lower inner side of the sealing cover, a sliding plate is fixedly installed on the top of the pressure rod, and an air hole is provided on the top surface of the sealing cover.

[0011] Preferably, a transmission rod adapted to the arc-shaped head is fixedly installed on the top surface of the sliding plate, and the transmission rod passes through the air hole.

[0012] Preferably, the inner diameter of the second sealing cavity is at least larger than the inner diameter of the first sealing cavity, and the outer wall of the sliding plate is in contact with the inner wall of the first sealing cavity.

[0013] Preferably, the valve tube is made of a corrosion-resistant material.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up the valve cap and operating mechanism, and using the push rod and pressure plate, when air needs to be released, the operator only needs to operate the pressure plate to slide the push rod out of the valve cap, and invert the valve cap to squeeze the transmission rod through the push rod, which can realize the quick operation of the valve core. This greatly simplifies the operation process, improves work efficiency, and also reduces the risk of misoperation that may be caused by the use of tools.

[0016] 2. By setting up a transmission rod and a sealing mechanism, the valve stem not only achieves the first seal through direct contact between the sealing plate and the valve core shell, but also features a sliding plate that slides between sealing chamber one and sealing chamber two to achieve a second seal on the valve core shell. This dual sealing mechanism effectively improves the sealing performance of the valve stem, significantly reducing the risk of valve stem leakage even in harsh operating environments or during long-term use, thus ensuring tire pressure stability and driving safety.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 A corrosion-resistant and durable butyl rubber gasket valve includes a valve tube 1, with a butyl rubber gasket 2 at one end of the valve tube 1 and a valve cap 3 screwed to the end of the valve tube 1 away from the butyl rubber gasket 2. A valve core shell 5 is fixedly installed on the inner wall of the valve tube 1, and a pressure rod 6 is slidably installed on the inner wall of the valve core shell 5 via a bracket. A sealing plate 7 is fixedly installed at the bottom end of the pressure rod 6, and a spring 10 is fitted on the pressure rod 6. An operating mechanism 4 is provided on the top surface of the valve cap 3, and a sealing mechanism 8 is provided on the top surface of the valve core shell 5. The operating mechanism 4 on the top surface of the valve cap 3 facilitates inflation and deflation operations by the operator, while the sealing mechanism 8 on the top surface of the valve core shell 5 further improves the sealing performance of the valve.

[0024] Reference Figure 1 , Figure 2 The operating mechanism 4 includes a push rod 41 that passes through the top surface of the valve cap 3 and is slidably connected to the through point. A pressure plate 42 is fixedly installed at one end of the push rod 41 located inside the valve cap 3. A spring 43 is fitted on the outer wall of the push rod 41 located between the pressure plate 42 and the valve cap 3. An arc-shaped head 44 is fixedly installed at one end of the push rod 41 located outside the valve cap 3. By pressing the pressure plate 42, the push rod 41 slides out of the valve cap 3, and the valve cap 3 is inverted. By passing the push rod 41 and the arc-shaped head 44, the valve core can be operated quickly, which greatly simplifies the operation process.

[0025] Reference Figure 2 The outer wall of the pressure plate 42 fits against the inner wall of the nozzle cap 3, ensuring that the push rod 41 will not wobble during sliding, thereby improving the stability and accuracy of operation.

[0026] Reference Figure 3 , Figure 4The sealing mechanism 8 includes a sealing cover 81 fixedly installed on the top surface of the valve core housing 5. A sealing cavity 82 is provided on the upper inner side of the sealing cover 81, and a sealing cavity 83 is provided on the lower inner side of the sealing cover 81. A sliding plate 84 is fixedly installed on the top of the pressure rod 6. An air hole 85 is provided on the top surface of the sealing cover 81. The sliding plate 84 can slide between the sealing cavity 82 and the sealing cavity 83, thereby achieving a double seal on the valve core housing 5. The air hole 85 on the top surface of the sealing cover 81 facilitates the flow of gas.

[0027] Reference Figure 4 A transmission rod 9 adapted to the arc-shaped head 44 is fixedly installed on the top surface of the sliding plate 84, and the transmission rod 9 passes through the air hole 85; this ensures that when the top rod 41 is pressed down, the arc-shaped head 44 can push the transmission rod 9, thereby driving the sliding plate 84 to slide between the sealing cavity 1 82 and the sealing cavity 2 83.

[0028] Reference Figure 4 The inner diameter of the second sealing cavity 83 is at least larger than the inner diameter of the first sealing cavity 82, and the outer wall of the sliding plate 84 is in contact with the inner wall of the first sealing cavity 82; the tight contact between the outer wall of the sliding plate 84 and the inner wall of the first sealing cavity 82 ensures the tightness of the seal.

[0029] Reference Figure 1 The valve tube 1 is made of corrosion-resistant material, which not only extends the service life of the valve but also improves its stability in harsh environments.

[0030] The specific working principle of this utility model is as follows:

[0031] When in use, the valve tube 1 and butyl rubber gasket 2 can be installed on the wheel hub of the vehicle. If it is necessary to deflate the tire during normal use, the operator can remove the valve tube 1 from the valve cap 3, and then press the pressure plate 42 to make the push rod 41 slide out of the valve cap 3. The length of the push rod 41 outside the valve cap 3 becomes longer, so the valve cap 3 can be inverted and the push rod 41 and the arc head 44 can be used to squeeze the transmission rod 9.

[0032] When the transmission rod 9 is compressed, it can drive the sliding plate 84 to slide downward, thereby separating the sealing plate 7 at the bottom of the pressure rod 6 from the valve core shell 5. At the same time, the sliding plate 84 slides from the first sealing cavity 82 to the second sealing cavity 83, and the gas can be discharged through the valve core shell 5 and the sealing cover 81. After the inflation and deflation are completed, the transmission rod 9 and the sliding plate 84 can be reset under the action of the second spring 10. At this time, the sliding plate 84 is back in the first sealing cavity 82 to seal the valve core shell 5, realizing the second seal of the valve nozzle, effectively reducing the risk of valve nozzle leakage.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
