Description

Technical Field

[0001] This utility model relates to the field of sealing ring technology, specifically a high-temperature resistant and chemically corrosion resistant rubber sealing ring. Background Technology

[0002] In today's industrial production and pipeline transportation fields, rubber seals are widely used in various applications as key components to ensure the sealing performance of pipeline systems. Especially under extreme conditions such as high temperature and high chemical corrosion, even more stringent requirements are placed on the performance of rubber seals.

[0003] Currently, many sealing rings are not securely fixed after installation. When the rubber ring needs to be replaced due to corrosion or other reasons, the disassembly process is usually quite complicated. It often requires the use of special tools or a lot of time and effort to remove the fixing restrictions on the rubber ring. This not only reduces maintenance efficiency but also increases equipment downtime and maintenance costs. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a high-temperature and chemically resistant rubber sealing ring, solving the problem of complex disassembly processes for rubber sealing rings.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature and chemically resistant rubber sealing ring, comprising a gasket, wherein a gas storage chamber is formed in the wall of the gasket, and further comprising: a connecting component, wherein the rubber ring is snapped into the inner side of the connecting component, the inner side of the rubber ring is coated with an anti-corrosion coating, the connecting component comprising an annular block, an annular limiting block is fixedly connected to the inner side of the annular block, a snap-fit ​​block is slidably connected to the inner wall of the annular block, and a gas guide groove is formed in the wall of the annular block, which compresses the two pipes, causing the gasket to undergo elastic deformation, and the gas in the gas storage chamber is squeezed into the gas guide groove in the annular block, and then squeezes the snap-fit ​​block through the gas guide hole.

[0008] Preferably, the outer side of the annular block is fixedly connected to the inner side of the washer, and the outer side of the snap-fit ​​block is in contact with the outer wall of the rubber ring. When the snap-fit ​​block is pushed out, it can be snapped into the groove on the surface of the rubber ring to further limit its position and prevent it from detaching from the connecting component during use.

[0009] Preferably, the outer side of the rubber ring is engaged with the inner wall of the annular block through a mounting groove, and the mounting groove is opened in the wall of the annular block. When the rubber ring is installed on the inner side of the connecting component, it can be engaged in the mounting groove opened in the wall of the annular block.

[0010] Preferably, the annular block has air guide holes in its wall, and the air guide holes are arranged in a ring along the central axis of the annular block, so that the air in the air guide groove can squeeze the clamping block through the air guide holes.

[0011] Preferably, a retaining strip is fixedly connected to the outer side of the rubber ring, and the retaining strip is symmetrically arranged along the central axis of the rubber ring. The two sides of the annular block are engaged with the outer side of the retaining strip through retaining grooves, and the retaining grooves are opened in the side wall of the annular block. By inserting the retaining strip into the retaining groove, the position of the rubber ring relative to the connecting component can be initially restricted.

[0012] (III) Beneficial Effects

[0013] This invention provides a high-temperature resistant and chemically corrosion-resistant rubber sealing ring. It has the following beneficial effects:

[0014] (i) The sealing ring is installed on the inner side of the connecting component by setting a connecting component, so that it is locked in the installation groove opened in the annular block wall. Then, the locking strip is inserted into the locking groove to initially restrict the position of the rubber ring relative to the connecting component. Then, the two pipes can be pressed together, causing the gasket to undergo elastic deformation. The gas in this gas storage chamber is squeezed into the gas guide groove in the annular block. Then, the locking block is squeezed through the gas guide hole and pushed outward. When the locking block is pushed out, it can be locked into the groove on the surface of the rubber ring, further limiting its position and preventing it from detaching from the connecting component during use.

[0015] (II) This sealing ring incorporates a gas storage chamber. When the pipeline is removed, the gasket returns to its original shape, releasing the pressure within the chamber. The retaining block, which was originally pushed outwards and locked into the groove on the rubber ring's surface due to gas compression, then resets. This process automatically releases the retaining block from restricting the rubber ring, freeing it from additional fixing force and facilitating its removal. In environments with severe chemical corrosion where the rubber ring is easily damaged, the automatic reset of the retaining block ensures quick and convenient removal of the rubber ring each time it is replaced. This improves replacement efficiency, reduces equipment downtime, and lowers maintenance costs. Attached Figure Description

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

[0023] Example: Please refer to Figure 1-5 This utility model provides a technical solution: a high-temperature resistant and chemically corrosion-resistant rubber sealing ring, including a gasket 1, a gas storage chamber 3 formed in the wall of the gasket 1, and a connecting component 2. A rubber ring 4 is snapped into the inner side of the connecting component 2, and the inner side of the rubber ring 4 is coated with an anti-corrosion coating 6. The gasket 1 is the basic structure of the entire sealing ring. It covers the end faces of the two pipe joints and initially plays the role of blocking external substances from entering the pipe connection and preventing the leakage of substances inside the pipe. The anti-corrosion coating 6 coated on the inner side of the rubber ring 4 can effectively resist the corrosion of chemical substances inside the pipe. When corrosive liquids or gases are transported in the pipeline, the anti-corrosion coating 6 acts as a barrier to prevent chemicals from directly contacting the rubber ring 4, thereby extending the service life of the rubber ring 4 and ensuring the sealing performance of the sealing ring. The connecting assembly 2 includes an annular block 21, with an annular limiting block 24 fixedly connected to the inner side of the annular block 21. A snap-fit ​​block 25 is slidably connected to the inner wall of the annular block 21, and a gas guide groove 22 is provided in the wall of the annular block 21. First, the rubber ring 4 is installed on the inner side of the connecting assembly 2, so that it is snapped into the installation groove 26 opened in the wall of the annular block 21. Then, the snap-fit ​​strip 5 is installed. The rubber ring 4 is inserted into the slot 27, which initially restricts the position of the rubber ring 4 relative to the connecting component 2. Then, the two pipes can be pressed together, causing the gasket 1 to undergo elastic deformation. The gas in the gas storage chamber 3 is squeezed into the air guide groove 22 in the annular block 21, and then squeezed through the air guide hole 23 to push the snap-fit ​​block 25 outward. When the snap-fit ​​block 25 is pushed out, it can be inserted into the groove on the surface of the rubber ring 4, further limiting its position and preventing it from detaching from the connecting component 2 during use. The annular limiting block 24 is used to limit the maximum sliding stroke of the snap-fit ​​block 25.

[0024] The outer side of the annular block 21 is fixedly connected to the inner side of the gasket 1. The outer side of the snap-fit ​​block 25 contacts the outer wall of the rubber ring 4. The outer side of the rubber ring 4 is snapped into the inner wall of the annular block 21 through the mounting groove 26, and the mounting groove 26 is opened in the wall of the annular block 21. The wall of the annular block 21 is provided with air guide holes 23, and the air guide holes 23 are arranged in a ring along the central axis of the annular block 21. The outer side of the rubber ring 4 is fixedly connected with a snap-fit ​​strip 5, and the snap-fit ​​strip 5 is symmetrically arranged along the central axis of the rubber ring 4. The two sides of the annular block 21 are snapped into the outer side of the snap-fit ​​strip 5 through the snap-fit ​​groove 27, and the snap-fit ​​groove 27 is opened in the side wall of the annular block 21. When the pipe is removed, the gasket 1 returns to its deformation, the pressure in the gas storage chamber 3 is released, and the snap-fit ​​block 25, which was originally pushed outward and snapped into the groove on the surface of the rubber ring 4 due to gas compression, is reset. This process automatically releases the locking block 25 from restricting the rubber ring 4, so that the rubber ring 4 is no longer subject to additional fixing force, providing convenient conditions for the disassembly of the rubber ring 4. In the case of severe chemical corrosion environment, where the rubber ring 4 is easily damaged, the automatic reset of the locking block 25 can ensure that the rubber ring 4 can be quickly and conveniently disassembled each time it is replaced, thereby improving the replacement efficiency of the rubber ring 4, reducing equipment downtime, and reducing maintenance costs.

[0025] In use, gasket 1 is the basic structure of the entire sealing ring. It covers the end faces of the two pipe joints, initially preventing external substances from entering the pipe connection and preventing leakage of substances inside the pipe. The anti-corrosion coating 6 coated on the inner side of the rubber ring 4 effectively resists the corrosion of chemicals inside the pipe. When corrosive liquids or gases are transported in the pipe, the anti-corrosion coating 6 acts as a barrier to prevent chemicals from directly contacting the rubber ring 4, thereby extending the service life of the rubber ring 4 and ensuring the sealing performance of the sealing ring.

[0026] During installation, the rubber ring 4 is first installed inside the connecting component 2, so that it is locked in the mounting groove 26 opened in the wall of the annular block 21. Then, the locking strip 5 is inserted into the locking groove 27 to initially restrict the position of the rubber ring 4 relative to the connecting component 2. Then, the two pipes can be pressed together, causing the gasket 1 to undergo elastic deformation. The gas in the gas storage chamber 3 is squeezed into the air guide groove 22 in the annular block 21. Then, the locking block 25 is squeezed through the air guide hole 23, pushing the locking block 25 outward. When the locking block 25 is pushed out, it can be locked into the groove on the surface of the rubber ring 4, further limiting its position and preventing it from detaching from the connecting component 2 during use. The annular limiting block 24 is used to limit the maximum sliding stroke of the locking block 25.

[0027] When the pipe is removed, gasket 1 returns to its original shape, releasing the pressure inside the gas storage chamber 3. The retaining block 25, which was originally pushed outwards and locked into the groove on the surface of rubber ring 4 due to gas compression, then resets. This process automatically releases the retaining block 25 from the rubber ring 4, freeing it from additional fixing force and facilitating its removal. In environments with severe chemical corrosion where rubber ring 4 is easily damaged, the automatic reset of the retaining block 25 ensures quick and easy removal of rubber ring 4 each time it is replaced, thereby improving replacement efficiency, reducing equipment downtime, and lowering maintenance costs.
