Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] Please refer to Figures 1-5The utility model provides a technical scheme: a high elasticity high temperature resistance silica gel sealing ring structure, including first silica gel sealing ring 1, reinforcing ring 2, micro elastic hollow column 3, second silica gel sealing ring 4, third silica gel sealing ring 5, wear layer 6, waterproof layer 7, high elastic rubber layer 8, high temperature resistance layer 9, lug 10, through -hole 11, limit recess 12 and limit bolt 13, the outside installation of first silica gel sealing ring 1 has reinforcing ring 2, reinforcing ring 2 is metal material quality design, and reinforcing ring 2 is fixedly connected with first silica gel sealing ring 1, reinforcing ring 2 can bear greater pressure and external force, is not easy to deform and damage, has improved the reliability of the sealing ring, has guaranteed the good sealing performance under various working conditions, the inside of first silica gel sealing ring 1 is provided with micro elastic hollow column 3, and the upper and lower sides of micro elastic hollow column 3 are installed with second silica gel sealing ring 4 and third silica gel sealing ring 5 respectively, first silica gel sealing ring 1, second silica gel sealing ring 4 and third silica gel sealing ring 5 are coaxially arranged, and micro elastic hollow column 3 is clamped with first silica gel sealing ring 1, avoids the sealing not strictly because of different shafts, and micro elastic hollow column 3 is clamped with first silica gel sealing ring 1, strengthens internal structure stability, and micro elastic hollow column 3 can also provide elastic support, improves the elasticity of sealing ring, and better adapts to different sealing scenes, first silica gel sealing ring 1, second silica gel sealing ring 4 and third silica gel sealing ring 5 are sequentially provided with wear layer 6, waterproof layer 7, high elastic rubber layer 8 and high temperature resistance layer 9 from outside to inside, waterproof layer 7 is polytetrafluoroethylene material, wear layer 6 reduces the surface wear of the sealing ring, prolongs the service life, waterproof layer 7 prevents liquid penetration, and guarantees sealing effect, high elastic rubber layer 8 provides good elasticity, and ensures close fitting sealing surface.The high-temperature resistant layer 9 ensures stable performance at high temperatures. The polytetrafluoroethylene waterproof layer 7 has excellent waterproof and chemical stability, further enhancing its waterproof and corrosion-resistant capabilities. The upper surface of the second silicone sealing ring 4 is fitted with protrusions 10, which are distributed in a circular structure and are fixedly connected to the second silicone sealing ring 4. The protrusions 10 serve as guides. After installing the micro-elastic hollow column 3, the second silicone sealing ring 4, and the third silicone sealing ring 5, rotate these components to align the protrusions 10 on the second silicone sealing ring 4 with the limiting bolts 13, ensuring precise fit between components. The first silicone sealing ring 1 has a through hole 11, and the outer side of the micro-elastic hollow column 3 has a limiting groove 12. The reinforcing ring 2 is fitted with limiting bolts 13. Both the through hole 11 and the limiting groove 12 are circular. The structure is circular, with the same number and corresponding protrusions 10, through holes 11, limiting grooves 12, and limiting bolts 13. When under force, the limiting bolts 13 move inwards. The limiting bolts 13 abut against the limiting grooves 12 on the micro-elastic hollow column 3 through the through holes 11, thus limiting the micro-elastic hollow column 3 and preventing it from shifting. This also prevents the second silicone sealing ring 4 and the third silicone sealing ring 5 on the micro-elastic hollow column 3 from shifting. The limiting bolts 13 are circularly distributed, with their center lines coinciding with the center lines of the through holes 11 and the limiting grooves 12. The limiting bolts 13 pass through the through holes 11 on the first silicone sealing ring 1 and engage with the limiting grooves 12 on the micro-elastic hollow column 3. The limiting bolts 13 are threadedly connected to the reinforcing ring 2. Rotating the limiting bolts 13 allows for movement of their position.

[0031] Working principle: When using this high-elasticity, high-temperature resistant silicone sealing ring structure, firstly, the sealing ring assembly is installed on the part that needs to be sealed. When the sealing ring is subjected to external pressure, the high-elasticity rubber layer 8 exerts its elasticity, allowing the sealing ring assembly to fit tightly against the sealing surface, effectively preventing fluid leakage. At the same time, the reinforcing ring 2 is made of metal and is fixedly connected to the first silicone sealing ring 1, which can withstand greater pressure and external force, enhancing the overall structural strength of the sealing ring assembly and preventing it from deforming or being damaged under high pressure.

[0032] In high-temperature environments, the high-temperature resistant layer 9 plays a crucial role in ensuring that the sealing ring maintains good physical and sealing properties at high temperatures, and will not experience aging or deformation due to excessive temperature. The waterproof layer 7 is made of polytetrafluoroethylene, which has excellent waterproof and chemical stability, effectively preventing the corrosion of liquids and chemicals and ensuring the sealing effect. The wear-resistant layer 6 reduces frictional wear between the sealing ring assembly surface and other components, extending the service life of the sealing ring assembly.

[0033] When the micro elastic hollow column 3, the second silica gel sealing ring 4 and the third silica gel sealing ring 5 are installed, the limiting bolt 13 is rotated, the limiting bolt 13 moves inward under force, the limiting bolt 13 abuts against the limiting groove 12 on the micro elastic hollow column 3 through the through hole 11, thereby limiting the micro elastic hollow column 3, so that the micro elastic hollow column 3 is not easy to deviate, thereby the second silica gel sealing ring 4 and the third silica gel sealing ring 5 on the micro elastic hollow column 3 are not easy to deviate.

[0034] When the surface of the second silica gel sealing ring 4 and the third silica gel sealing ring 5 is damaged, the second silica gel sealing ring 4 and the third silica gel sealing ring 5 can be pulled out from the first silica gel sealing ring 1 under the action of the micro elastic hollow column 3, thereby facilitating the disassembly and replacement of the second silica gel sealing ring 4 and the third silica gel sealing ring 5, in an emergency, the first silica gel sealing ring 1 can be directly used, thereby improving the practicability of the sealing ring.

[0035] Thus a series of work is completed. The contents not described in detail in the specification belong to the prior art known by the person skilled in the art.

[0036] Although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, the technical scheme recorded in the foregoing embodiments can be modified, or part of the technical features can be replaced, any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
