Description

Technical Field

[0001] The utility model relates to the technical field of sealing, in particular to a sealing ring. Background Art

[0002] Sealing is a crucial link in industrial production and the operation of various mechanical equipment. As a widely used sealing component, the performance of the sealing ring directly affects the sealing, reliability and service life of the entire equipment.

[0003] The installation and removal of seals also become a key consideration. Due to their structural limitations, traditional seals can require complex tools and tedious procedures during installation, increasing both cost and time. The difficulty of removal is exacerbated when equipment maintenance or seal replacement is required. Some seals lack a design that facilitates removal, which can easily damage the seal itself or associated equipment components, further increasing maintenance costs and equipment downtime. Utility Model Content

[0004] In order to solve the technical problems existing in the background technology, the utility model proposes a sealing ring.

[0005] The utility model proposes a sealing ring, including a sealing ring body, which has a first sealing end face and a second sealing end face arranged perpendicular to the axial direction of the sealing ring body, the first sealing end face and the second sealing end face are arranged relatively parallel, and the sealing ring body has a first section and a second section, the first section that interrupts the first sealing end face extends smoothly to the second sealing end face, and the second section that interrupts the first sealing end face extends smoothly to the second sealing end face. When the sealing ring body is assembled and used, the first section and the second section fit together.

[0006] Preferably, the sealing ring body has an annular groove coaxially arranged with the sealing ring body. When the sealing ring body is assembled and used, a tape layer is wound and adhered in the annular groove to prevent the first section from separating from the second section.

[0007] Preferably, a lap portion extends from one side of the first section, and a lap groove is provided on one side of the second section. When the sealing ring body is assembled and used, the lap portion is adapted to be received in the lap groove.

[0008] Preferably, the groove depth of the overlapping groove gradually increases in a direction away from the second section.

[0009] Preferably, the bottom of the overlapping groove is frosted, and when the sealing ring body is assembled and used, the bottom of the overlapping portion that contacts the bottom of the overlapping groove is frosted.

[0010] Preferably, a step is formed between the overlapping groove and the annular groove, and the width of the overlapping groove is equal to the width of the annular groove.

[0011] Preferably, at least one protrusion extends from the first section, and at least one slot is provided on the second section. When the sealing ring body is assembled and used, the protrusions are inserted into the slots one by one.

[0012] The utility model proposes a sealing ring, which has the following advantages: by providing a first section and a second section to interrupt the sealing ring body, the sealing ring can be easily disassembled, maintenance time and cost can be effectively reduced, and maintenance efficiency can be improved. The overlapping portion of the first section is adapted to the overlapping groove of the second section, and the overlapping groove depth gradually increases, so that the overlapping portion can be inserted more smoothly and the connection is more stable, ensuring smooth assembly. The step design between the overlapping groove and the annular groove and the equal groove width of the two are conducive to dimensional control during manufacturing and cooperation with other components during assembly, ensuring the coordination and stability of the sealing system. The first sealing end face and the second sealing end face are arranged relatively parallel, and the contact with the sealed component is stable and uniform, laying the foundation for good sealing. The tape layer in the annular groove can prevent the first section and the second section from separating. It has good viscosity and corrosion resistance, and can ensure the overall sealing and reliability of the sealing ring for a long time. The frosting treatment of the overlapping groove and the bottom of the overlapping portion increases friction, avoids relative sliding between the two under complex working conditions, and ensures working stability. The raised portion of the first section and the slot of the second section correspond one to one, limiting and constraining the sections in the axial and circumferential directions, ensuring sealing performance under various stress conditions and guaranteeing safe and reliable operation of the sealing system.

[0018] refer to Figure 1-5The utility model proposes a sealing ring, including a sealing ring body 1. On the sealing ring body 1, a first sealing end face 2 and a second sealing end face 3 are arranged perpendicular to its axial direction. The two sealing end faces are arranged relatively parallel. The first sealing end face 2 and the second sealing end face 3 can form stable and uniform contact with the sealed component, like two perfectly fitting planes, thereby enhancing the sealing effect.

[0019] The sealing ring body 1 also includes a first section 4 and a second section 5. The first section 4, which interrupts the first sealing end face 2, smoothly extends to interrupt the second sealing end face 3. Similarly, the second section 5, which interrupts the first sealing end face 2, also smoothly extends to interrupt the second sealing end face 3. When the sealing ring body 1 is assembled and used, the first section 4 and the second section 5 can precisely fit together. The provision of the first section 4 and the second section 5 to interrupt the sealing ring body 1 facilitates disassembly of the sealing ring body 1. In actual industrial applications, the removal and replacement of sealing rings is a key part of maintenance work. This design can effectively reduce maintenance time and costs and improve work efficiency.

[0020] The sealing ring body 1 is also provided with an annular groove 6 coaxially arranged with the sealing ring body 1. After the sealing ring body 1 is assembled, a tape layer 7 is wound and adhered within the annular groove 6, effectively preventing the first section 4 from separating from the second section 5. The tape layer 7 is a key element in ensuring the sealing ring body 1 maintains a tight structure after assembly. The tape layer 7 firmly binds the first section 4 and the second section 5 together over long-term use. Its excellent corrosion resistance ensures its stable performance even in harsh operating environments, such as exposure to various chemicals and temperature fluctuations, further ensuring the sealing and reliability of the sealing ring.

[0021] Furthermore, in the sealing ring's structural design, a lap joint 8 extends from one side of the first section 4, while a corresponding lap groove 9 is provided on the other side of the second section 5. When the sealing ring body 1 is assembled, the lap joint 8 fits perfectly within the lap groove 9. This lap joint structure acts like a lock, tightly connecting the two sections and providing a strong guarantee for the overall stability of the sealing ring.

[0022] Furthermore, in the direction away from the second section 5, the groove depth of the overlapping groove 9 shows a characteristic of gradually increasing. It makes the overlapping part 8 smoother during the insertion process of the overlapping groove 9, and will not cause assembly difficulties due to sudden changes in resistance. Moreover, as the insertion depth increases, the connection between the overlapping part 8 and the overlapping groove 9 will become more and more stable due to the change in groove depth. At the same time, the bottom of the overlapping groove 9 is frosted, and when the sealing ring body 1 is assembled and used, the bottom of the overlapping part 8 that contacts the bottom of the overlapping groove 9 is also frosted. This frosting treatment increases the friction between the overlapping part 8 and the overlapping groove 9. During the operation of the sealing ring, the existence of friction can greatly enhance the stability of the connection between the two, ensure the stable operation of the sealing ring, and prevent sealing failure due to loosening.

[0023] In addition, a step is formed between the overlapping groove 9 and the annular groove 6, and the groove width of the overlapping groove 9 is equal to the groove width of the annular groove 6. This design not only ensures the compactness of the entire sealing ring structure, but also brings convenience to the manufacturing process.

[0024] At least one protrusion 10 extends from the first section 4, while the second section 5 has at least one slot 11. When the sealing ring body 1 is assembled and used, the protrusions 10 correspond one-to-one with the slots 11, allowing the protrusions 10 to be inserted accurately into the slots 11. This design of protrusions and slots provides an additional layer of reliability for the sealing ring connection. Their tight fit not only strictly limits the section in the axial direction, preventing relative displacement, but also provides a stable constraint in the circumferential direction. This means that no matter which direction the sealing ring is subjected to force during operation, this design maintains excellent sealing performance.

[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution of the present invention and the concept of the present invention, should be covered by the protection scope of the present invention.
