Especially in high-pressure and high-temperature environments, the sealing performance is easily affected, leading to leakage problems. In addition, the single sealing structure lacks sufficient adaptability and cannot effectively cope with temperature changes and pressure fluctuations, and the service life of the sealing ring is limited. Therefore, a multi-functional composite sealing ring is proposed. Summary of the Utility Model

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Refer to Figures 1 to 3, Multifunctional composite material sealing ring, including a ring body 1. Grooves 2 are provided on the upper and lower sides of the ring body 1, and the shape is rectangular, which increases the contact area between the sealing ring and the mating surface, thereby improving the sealing effect, effectively preventing liquid or gas leakage, and also helping to fix the position of the sealing ring, preventing it from moving during installation and shifting due to pressure changes during use, ensuring the stability and reliability of the seal. A convex ball 3 is fixedly connected to the outside of the ring body 1. There are multiple convex balls 3 on the sealing ring, and these convex balls 3 can be inserted into the pipe orifice to be sealed to achieve layer-by-layer sealing, thus greatly improving the sealing effect. An extension ring 4 is fixedly connected to the outside of the ring body 1, which can provide sealing effects in both the radial and axial directions, enhancing the reliability of the seal. A metal mesh 5 is fixedly installed inside the ring body 1. The metal mesh 5 can effectively disperse pressure and reduce material fatigue, thereby extending the service life of the sealing ring. At the same time, the presence of the metal mesh 5 can also improve the adaptability of the sealing ring to extreme temperature fluctuations and maintain its performance stability within a wide temperature range. The outside of the metal mesh 5 is fixedly connected to the outside of the extension ring 4;

[0023] Refer to Figure 1 , Figure 4 , An anti-wear material layer 6 is fixedly connected to the outside of the ring body 1, and the material is polytetrafluoroethylene (PTFE), which improves the wear resistance of the sealing ring and extends its service life. A high-temperature resistant material layer 7 is fixedly connected to the inside of the ring body 1, and the material is silicone rubber, which can maintain stable performance at high temperatures and prevent the sealing ring from deforming or failing. The outside of the high-temperature resistant material layer 7 is fixedly connected to the outside of the metal mesh 5.

[0024] Working principle: First, the ring body 1, as the main body of the sealing ring, is designed with rectangular grooves 2 on its upper and lower sides. These grooves 2 increase the contact area between the sealing ring and the mating surface, thereby improving the sealing effect and effectively preventing the leakage of liquid or gas. During installation, the design of the grooves 2 also helps to fix the position of the sealing ring and avoid displacement caused by pressure changes, ensuring the stability and reliability of the seal. On the outside of the sealing ring, multiple convex balls 3 are arranged on the ring body 1, and these convex balls 3 can be inserted into the pipe orifice to be sealed to achieve layer-by-layer sealing, further enhancing the sealing effect. At the same time, an extension ring 4 is fixedly connected to the outside of the ring body 1, and this extension ring 4 provides sealing effects in both the radial and axial directions, increasing the reliability of the seal. A metal mesh 5 is fixed inside the sealing ring, and the function of the metal mesh 5 is to effectively disperse pressure and reduce material fatigue, thereby extending the service life of the sealing ring. In addition, the presence of the metal mesh 5 improves the adaptability of the sealing ring to extreme temperature fluctuations and ensures its performance stability within a wide temperature range. The outside of the metal mesh 5 is connected to the extension ring 4 to form a complete sealing structure;

[0025] To enhance the wear resistance of the sealing ring, an anti-wear material layer 6 made of polytetrafluoroethylene (PTFE) is fixedly connected to the outside of the ring body 1, further extending the service life. Inside the ring body 1, a high-temperature resistant material layer 7 made of silicone rubber is fixedly connected to ensure the stable performance of the sealing ring in a high-temperature environment and prevent deformation or failure caused by high temperature. The high-temperature resistant material layer 7 is located outside the metal mesh 5 to form an integrated sealing structure. Through the above design, the sealing ring can effectively achieve the sealing function under various working conditions.

[0026] 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.
