Abstract
Description
Technical Field
[0001] This utility model provides a sealing ring, belonging to the field of sealing technology, and particularly relates to a high-sealing embedded silicone sealing ring. Background Technology
[0002] A sealing ring, a rubber product used for connection and sealing, is widely used in automobiles, home appliances, machinery, and other fields. It is typically made of rubber, possessing good elasticity and wear resistance. The main function of a sealing ring is to prevent liquid or gas leakage, ensuring the normal operation and safety of equipment. In terms of design, sealing rings usually have a wear-resistant layer and a highly elastic sealing layer to adapt to different working environments and requirements. Furthermore, the structural design of the sealing ring is also very important; for example, the "I"-shaped annular plate structure of the clamp and cap ensures a tight fit between the sealing ring and the equipment, further improving sealing performance.
[0003] Existing sealing rings are typically single rubber rings, primarily made of rubber material, with a simple annular structure, relying on the elasticity of rubber to achieve a sealing function. While these single rubber sealing rings can meet basic sealing requirements to a certain extent, the single rubber material struggles to simultaneously possess good wear resistance and high elasticity in different working environments, resulting in unstable sealing performance. Secondly, the structure of a single rubber sealing ring cannot effectively cope with complex operating conditions such as high pressure and high temperature, making it prone to leakage problems; the lack of auxiliary structures may lead to inconvenient installation and affect the sealing effect. Utility Model Content

[0020] 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.
[0021] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.
[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0023] like Figure 1 and Figure 2 As shown, this utility model provides the following technical solution: a high-sealing embedded silicone sealing ring, comprising a plurality of uniformly distributed silicone rings 1, characterized in that: a clamp 2 is provided between the silicone rings 1 and correspondingly fitted to itself, and a cap 3 is provided on the side of the silicone ring 1 away from another silicone ring 1 and fitted to itself; the silicone ring 1 includes a wear-resistant layer 4 fitted to the clamp 2 and the cap 3, and a highly elastic sealing layer 5 is provided between the wear-resistant layers 4. The silicone ring 1 has grooves 6 on both sides, the depth of which does not exceed half the thickness of the clamp 2, ensuring a tight connection between the silicone rings 1 on both sides of the clamp 2. The clamp 2 and the cap 3 are I-shaped annular plates of different thicknesses, making their fit with the silicone rings 1 even tighter and effectively preventing liquid or gas leakage from between the silicone rings 1.
[0024] In this embodiment, a multi-layer embedded structure is formed by evenly distributing several silicone rings 1, setting clamps 2 between adjacent silicone rings 1, and setting a cap 3 on the outside of each silicone ring 1. This structure not only enhances the overall stability of the sealing ring, but also significantly improves the wear resistance and elasticity of the sealing ring through the layered design of the wear-resistant layer 4 and the high-elasticity sealing layer 5. Specifically, the wear-resistant layer 4 uses high-hardness silicone material with a Shore hardness between 60 and 70A, which can effectively resist external mechanical stress and friction, and extend the service life of the sealing ring; while the high-elasticity sealing layer 5 uses low-hardness silicone material with a Shore hardness between 30 and 40A, which can tightly fit the sealed surface and further improve the sealing performance. In addition, the "I"-shaped annular plate structure design of the clamps 2 and the cap 3 makes their fit with the silicone rings 1 tighter, effectively preventing liquid or gas leakage from between the silicone rings 1. This combination of multi-layer embedded structure and optimized materials significantly improves the sealing performance and durability of the sealing ring under complex working conditions such as high pressure and high temperature. This solves the problems of unstable sealing performance, easy wear and short service life of traditional sealing rings in these environments, and significantly improves the reliability and safety of the equipment.
[0025] like Figure 3 and Figure 4 As shown, the high-elasticity sealing layer 5 is made of low-hardness silicone with a Shore hardness between 30 and 40A, which allows it to tightly adhere to the sealed surface, further improving sealing performance. The wear-resistant layer 4 is made of high-hardness silicone with a Shore hardness between 60 and 70A, possessing good wear resistance and mechanical strength, extending the service life of the sealing ring. The silicone ring 1 is coated with an anti-aging film, and chemical agents are filled between the clamp 2, the cap 3, and the silicone ring 1 to enhance the sealing effect and durability.
[0026] In this embodiment, a multi-layered sealing ring is formed by combining a highly elastic sealing layer 5 and a wear-resistant layer 4. This design not only improves the elasticity and wear resistance of the sealing ring but also further enhances the sealing effect through the filling of chemical agents. Specifically, the highly elastic sealing layer 5 can tightly adhere to the sealed surface, effectively preventing liquid or gas leakage, while the wear-resistant layer 4 can resist external mechanical stress and friction, extending the service life of the sealing ring. In addition, the coating of the anti-aging film and the filling of chemical agents enable the sealing ring to maintain good sealing performance and durability even under harsh environments such as high temperature and high pressure. This combination of multi-layered structure and optimized materials significantly improves the overall performance of the sealing ring, solving the problems of unstable sealing performance, easy wear, and short service life of traditional sealing rings under high pressure and high temperature environments, thereby improving the reliability and safety of the equipment.
[0027] It should be noted that when considering chemical agents to enhance sealing performance, N,N-dimethylcyclohexylamine (DMCHA) can be considered. This compound has excellent reactivity and stability, and can undergo cross-linking reactions with a variety of materials to form a strong and durable sealing layer. DMCHA acts as a catalyst in sealant formulations, promoting the cross-linking reaction between isocyanates and polyols in polyurethane sealants, thereby improving the curing speed and mechanical properties of the sealant, such as tensile strength and tear strength. Furthermore, DMCHA can significantly improve the weather resistance of sealants, maintaining stable performance under environmental conditions such as temperature changes, humidity, and UV exposure. Another possible chemical agent is a fluorinated gas used for fluorination of the silicone ring surface. By fluorinating the silicone ring in a fluorinated atmosphere, the surface of the silicone can be fluorinated, thereby improving the anti-stick properties of the silicone ring. This treatment method can effectively prevent the silicone ring from sticking during use, thus improving its performance. In addition, silicone sealing rings may require a post-curing process during production, a heat treatment process used to improve the physical properties and chemical stability of silicone products. Secondary vulcanization can eliminate internal stress and improve the elasticity and sealing performance of silicone seals.
[0028] When using this high-sealing embedded silicone seal ring, first check the integrity of the seal ring, ensuring that the silicone ring 1, clamp 2, and cap 3 are undamaged. Then, install the seal ring at the equipment interface requiring sealing, ensuring the wear-resistant layer 4 and the high-elasticity sealing layer 5 are correctly fitted. Next, install the clamp 2 and cap 3 on both sides of the silicone ring 1, ensuring a tight fit. Finally, check the sealing effect through a pressure test to ensure no leakage. During use, regularly check the wear condition of the seal ring and maintain or replace it as needed to ensure long-term reliable operation of the equipment.
[0029] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
