[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Referring to Figures 1 to 3 , a high-temperature and corrosion-resistant sealing ring, including sealing ring 1. Sealing ring 1 is in a regular annular shape and is made of high-quality rubber material, having good elasticity and sealing performance. Its outer surface is smooth. During use, sealing ring 1 closely adheres to the part to be sealed, bears the pressure from the inside and outside, and always maintains a good sealing state to prevent the leakage of gas or liquid. A heat-conducting pad 2 is fixedly connected to the bottom of sealing ring 1. Heat-conducting pad 2 is in a flat rectangular shape with a moderate thickness. It is composed of a metal material with good heat-conducting performance and a special insulating material. During operation, heat-conducting pad 2 can quickly conduct the heat generated at sealing ring 1 out, avoiding damage to the sealing ring due to high temperature. Its surface has been finely processed and is firmly connected to sealing ring 1 and oil storage ring 3, and will not fall off easily. A heat-conducting pad 2 is fixedly connected to the bottom of heat-conducting pad 2. Oil storage ring 3 is also in an annular shape, and the material is a special plastic resistant to oil and corrosion. A plurality of heat dissipation holes 4 are formed in the outside of oil storage ring 3. Heat dissipation holes 4 are like small channels, providing a path for heat dissipation. The inner wall of heat dissipation holes 4 is smooth, which helps the flow of air, thereby accelerating heat dissipation;

[0026] When the sealing ring is working, as the temperature rises, the surrounding air will exchange heat with the sealing ring through heat dissipation holes 4, taking away the heat and keeping the temperature of the sealing ring within a reasonable range. A sealing ring 5 is fixedly connected to the bottom of oil storage ring 3. The shape and material of sealing ring 5 are similar to those of sealing ring 1, but may be slightly different in size. It is also made of rubber material and has good high-temperature and corrosion-resistant performance. Sealing ring 5 cooperates with sealing ring 1 during operation to further enhance the sealing effect. When subjected to external extrusion, sealing ring 5 will undergo elastic deformation and closely adhere to the sealing part to prevent leakage;

[0027] Inside the first sealing ring 1, there is an anti-corrosion layer 6 made of polytetrafluoroethylene, which covers the inner surface of the first sealing ring 1 in the form of a uniform coating. This anti-corrosion material has strong chemical stability and can resist the erosion of various corrosive media. During use, the anti-corrosion layer 6 is always in contact with the sealing medium, effectively protecting the main structure of the first sealing ring 1 from corrosion and extending the service life of the sealing ring. At the bottom of the anti-corrosion layer 6, there is a heat-insulating layer 7 fixedly connected. The heat-insulating layer 7 is a thin layer of asbestos fiber and is composed of a material with excellent heat-insulating performance. Its shape matches the inner shape of the first sealing ring 1 and closely adheres to the lower part of the anti-corrosion layer 6. The function of the heat-insulating layer 7 is to prevent the external high temperature from being transmitted to the inside of the sealing ring and protect the internal structure of the sealing ring from the influence of high temperature. When working in a high-temperature environment, the heat-insulating layer 7 can effectively reduce the temperature inside the sealing ring and ensure the stable performance of the sealing ring. At the bottom of the heat-insulating layer 7, there is an anti-tear component fixedly connected to prevent damage caused by external force. The anti-tear component includes an anti-tear layer 8 made of high-strength polyester fiber, which is distributed in the form of a network structure inside the first sealing ring 1. This fiber material has high tensile strength and toughness and can effectively resist the tearing and stretching of external forces;

[0028] The outside of the anti-tear layer 8 is fixedly connected to the inside of the first sealing ring 1, closely combined with the heat-insulating layer 7 and the main structure of the first sealing ring 1 to form a solid whole. The outside of the anti-tear layer 8 is fixedly connected to the outside of the heat-insulating layer 7, and the outside of the anti-tear layer 8 is also fixedly connected to the outside of the heat-insulating layer 7, further enhancing the stability and anti-tear performance of the heat-insulating layer 7;

[0029] Refer to Figures 3 to 4 , at the bottom of the anti-tear layer 8, there is a non-slip layer 9 fixedly connected. The non-slip layer 9 presents a regular shape, and its material has excellent non-slip performance. The outside is closely and firmly fixedly connected to the inside of the first sealing ring 1. The outside of the non-slip layer 9 is fixedly connected to the inside of the first sealing ring 1, the outside of the heat-insulating layer 7 is arranged inside the first sealing ring 1, and the heat-insulating layer 7 also exists in a specific form. Its outside is carefully arranged inside the first sealing ring 1 and is very closely combined with the first sealing ring 1. The outside of the anti-tear layer 8 is arranged inside the first sealing ring 1, the outside of the heat-conducting pad 2 is fixedly connected to the inside of the second sealing ring 5, and the outside of the oil storage ring 3 is fixedly connected to the inside of the first sealing ring 1.

[0030] Working principle: During the installation process, the first sealing ring 1 is first placed at the part that needs to be sealed. Its elasticity and sealing performance can ensure a tight fit at the part that needs to be sealed. The heat-conducting pad 2 connected to the bottom of the first sealing ring 1 is responsible for quickly conducting the heat generated by the first sealing ring 1 to prevent damage to the sealing ring due to high temperature. At the same time, the oil storage ring 3 connected to the heat-conducting pad 2 is responsible for storing grease to provide lubrication and reduce the friction between the sealing ring and the fittings. A plurality of heat dissipation holes 4 are provided on the outside of the oil storage ring 3, and these heat dissipation holes 4 contribute to the circulation of air and accelerate the dissipation of heat, thereby keeping the temperature of the sealing ring within a reasonable range.

[0031] An anti-corrosion layer 6 is provided inside the first sealing ring 1. The anti-corrosion layer 6 can effectively protect the main structure of the first sealing ring 1 from being corroded and extends the service life of the sealing ring. The bottom of the anti-corrosion layer 6 is fixedly connected with a heat-insulating layer 7. The function of the heat-insulating layer 7 is to prevent the external high temperature from being transmitted to the inside of the sealing ring and protect the internal structure of the sealing ring from the influence of high temperature. An anti-tear layer 8 is also provided inside the first sealing ring 1. The anti-tear layer 8 is made of high-strength polyester fiber and is distributed in a net-like structure inside the first sealing ring 1, and can effectively resist the tearing and stretching of external forces. Finally, the bottom of the anti-tear layer 8 is fixedly connected with an anti-slip layer 9. The anti-slip layer 9 can enhance the stability of the sealing ring and prevent it from sliding during the working process.

[0032] In the whole working process, this high-temperature and corrosion-resistant sealing ring ensures the sealing effect through a multi-layer protection mechanism, prevents the invasion of heat and corrosive media, and at the same time resists the tearing and stretching of external forces, thereby ensuring its stable working performance in high-temperature and corrosive environments and extending its service life.
