Description

Technical Field

[0001] This utility model relates to the field of sealing ring technology, specifically a double-layer wear-resistant sealing ring. Background Technology

[0002] Sealing rings are key components in industrial equipment used to block fluid leakage paths. Sealing rings have characteristics such as corrosion resistance, tear resistance, compression deformation resistance, ozone resistance, and sunlight resistance.

[0003] The utility model CN219549588U discloses a double-layer reinforced sealing ring, including an installation ring, an inner fixing ring inside the installation ring, an installation groove on the outer surface of the installation ring, an outer fixing ring inside the installation groove, a buffer groove on the inner wall of the installation groove, and an elastic ring inside the buffer groove.

[0004] The above technical solution utilizes the cooperation of the mounting ring and the mounting groove to install the external fixing ring, allowing workers to replace and maintain it. This ensures the stable and reliable use of the sealing ring and avoids the need for complete replacement, thus reducing the cost of using the sealing ring. The inclusion of a buffer groove allows for the installation of an elastic ring inside. The elasticity of the elastic ring continuously applies pressure to the external fixing ring, pushing it into close contact with the inner wall of the assembled workpiece, further improving its sealing performance. However, prolonged use and contact with the external environment cause wear and tear on the outer wall of the sealing ring, reducing its sealing effect. Furthermore, the sealing ring has low toughness; prolonged compression or pulling can cause breakage and damage, affecting the continued sealing fit. Utility Model Content

[0005] The purpose of this invention is to provide a double-layer anti-wear sealing ring to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A double-layer wear-resistant sealing ring includes a sealing ring, an inner ring provided in the middle of the inner wall surface of the sealing ring, an outer ring symmetrically provided on the outer wall surface of the sealing ring, a wear-resistant rubber sleeve provided on the outer wall of the sealing ring, an annular groove provided in the middle area between the inner wall and the outer wall of the sealing ring, the annular groove being provided with a reinforcing rib for strengthening toughness, and a circular groove provided in the middle of the outer ring, the circular groove being provided with reinforcing ribs;

[0008] A connecting groove is provided in the middle of the outer wall of the sealing ring, and a buffer collar is provided in the connecting groove. The hollow area between the inner wall and the outer wall of the buffer collar is a sandwich layer.

[0009] Furthermore, a groove is provided on the inner wall of the wear-resistant rubber sleeve, and the width of the inner wall of the groove is adapted to the width of the outer wall of the sealing ring.

[0010] In this invention, the wear-resistant rubber sleeve is made of polytetrafluoroethylene, and the groove wraps around the sealing ring to protect the outer ring of the sealing ring, increase wear resistance, and extend the service life of the sealing ring.

[0011] Specifically, the wear-resistant rubber sleeve has a raised ring on the outer wall corresponding to the outer ring. The raised ring and the wear-resistant rubber sleeve are integrally formed. The width of the inner wall of the raised ring is matched with the width of the outer wall of the outer ring.

[0012] In this invention, the convex ring, in conjunction with the outer ring on the outer wall of the sealing ring, wraps and fits the outer ring, increasing the overall aesthetics, and at the same time achieving a double-layer sealing fit.

[0013] It should be noted that the width of the groove edge on the inner wall of the wear-resistant rubber sleeve is adapted to the width of the outer wall of the inner ring.

[0014] In this invention, the end distance on the inner wall of the wear-resistant rubber sleeve is closely fitted with the inner ring, so as to achieve a close fit between the wear-resistant rubber sleeve and the sealing ring, thereby increasing the tightness of the assembly and improving the overall aesthetics.

[0015] Furthermore, the inner wall surface of the inner ring is tightly bonded and fixed to the inner wall surface of the sealing ring, and the inner wall surface of the outer ring is tightly bonded and fixed to the outer wall surface of the sealing ring.

[0016] In this invention, the inner ring and outer ring are bonded together, which increases the stability of the assembly. The cooperation of the two outer rings increases the sealing performance of the double-layer fit. The inner ring adheres to the outer edge of the sealing element, reducing the impact of wear and tear on the contact sealing ring, increasing wear resistance, and further extending the overall service life.

[0017] Specifically, the inner diameter of the annular groove is adapted to the outer diameter of the reinforcing rib, and the reinforcing rib is bonded and fixed to the outer ring.

[0018] In this invention, the reinforcing ribs are inserted into the annular grooves to increase the toughness of the outer rings. Both outer rings are fitted with reinforcing ribs to increase the overall tensile toughness.

[0019] It is worth noting that the width of the inner wall of the annular groove is adapted to the width of the outer wall of the reinforcing strip, and the reinforcing strip is bonded and fixed to the annular groove.

[0020] In this invention, the reinforcing strip and the annular groove are interlocked to increase the overall tensile strength of the sealing ring and reduce deformation and breakage caused by long-term compression or pulling, which affects long-term use.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This utility model achieves a double-layer sealing fit by setting a sealing ring with an inner ring and two outer rings. The wear-resistant rubber sleeve is fitted on the sealing ring, and the groove fits tightly with the sealing ring, which protects the sealing ring and reduces the impact of external contact on the sealing ring, thus reducing wear and tear. The reinforcing rib is installed in the outer ring, which initially increases the toughness of the outer ring. The rib strip is inserted and fitted with the sealing ring, which further increases the overall tensile toughness, reduces deformation and breakage, and ensures long-term use.

[0023] 2. This utility model increases the impact of the outer ring of the sealing ring on the internal damage by setting a buffer sleeve with a sandwich layer and fitting it with the connecting groove. The sandwich layer is hollow and filled with air. When the outer layer is squeezed, the buffer sleeve ring changes shape, reducing the impact of compression damage to the sealing ring.

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.

[0034] Please see Figures 1-6 This embodiment provides a technical solution:

[0035] A double-layer wear-resistant sealing ring includes a sealing ring 1, an inner ring 10 is provided in the middle of the inner wall surface of the sealing ring 1, and an outer ring 11 is symmetrically provided on the outer wall surface of the sealing ring 1. The inner wall surface of the inner ring 10 is tightly bonded and fixed to the inner wall surface of the sealing ring 1, and the inner wall surface of the outer ring 11 is tightly bonded and fixed to the outer wall surface of the sealing ring 1.

[0036] In this invention, the inner ring 10 and the outer ring 11 are bonded together to increase the stability of the assembly. The cooperation of the two outer rings 11 increases the sealing performance of the double-layer fit. The inner ring 10 fits against the outer edge of the sealing element to reduce the impact of wear and tear on the contact sealing ring 1, increase wear resistance, and further extend the overall service life.

[0037] Furthermore, a wear-resistant rubber sleeve 2 is provided on the outer wall of the sealing ring 1, and a groove 20 is provided on the inner wall of the wear-resistant rubber sleeve 2. The width of the inner wall of the groove 20 is adapted to the width of the outer wall of the sealing ring 1.

[0038] In this utility model, the wear-resistant rubber sleeve 2 is made of polytetrafluoroethylene, and the groove 20 wraps around the sealing ring 1, thereby protecting the outer ring of the sealing ring 1, increasing wear resistance, and extending the service life of the sealing ring 1.

[0039] Specifically, the outer wall of the wear-resistant rubber sleeve 2 is provided with a protruding ring 21 corresponding to the outer ring 11. The protruding ring 21 and the wear-resistant rubber sleeve 2 are integrally formed, and the width of the inner wall of the protruding ring 21 is matched with the width of the outer wall of the outer ring 11.

[0040] In this invention, the convex ring 21, in conjunction with the outer ring 11 on the outer wall of the sealing ring 1, wraps and fits the outer ring 11, increasing the overall aesthetics, and at the same time achieving double-layer sealing.

[0041] It should be noted that the width of the edge of the groove 20 on the inner wall of the wear-resistant rubber sleeve 2 is adapted to the width of the outer wall of the inner ring 10.

[0042] In this invention, the end distance on the inner wall surface of the wear-resistant rubber sleeve 2 is closely fitted with the inner ring 10, so as to achieve a close fit between the wear-resistant rubber sleeve 2 and the sealing ring 1, thereby increasing the tightness of the assembly and improving the overall aesthetics.

[0043] Furthermore, an annular groove 14 is provided in the middle area between the inner wall and the outer wall of the sealing ring 1. The annular groove 14 is provided with a reinforcing rib 140 for strengthening toughness. A circular groove 110 is provided in the middle of the outer ring 11. A reinforcing rib 111 is provided in the circular groove 110.

[0044] Specifically, the inner diameter of the annular groove 110 is matched with the outer diameter of the reinforcing rib 111, and the reinforcing rib 111 is bonded and fixed to the outer ring 11.

[0045] In this utility model, the reinforcing rib 111 is inserted into the annular groove 110 to increase the toughness of the outer ring 11. Both outer rings 11 are fitted with reinforcing ribs 111 to increase the overall tensile toughness.

[0046] Secondly, the width of the inner wall of the annular groove 14 is adapted to the width of the outer wall of the reinforcing strip 140, and the reinforcing strip 140 is bonded and fixed to the annular groove 14.

[0047] In this invention, the reinforcing strip 140 is inserted into the annular groove 14 to increase the overall tensile strength of the sealing ring 1 and reduce deformation and breakage caused by long-term compression or pulling, which affects long-term use.

[0048] It is worth adding that a connecting groove 12 is provided in the middle of the outer wall of the sealing ring 1, and a buffer collar 13 is provided in the connecting groove 12. The hollow area between the inner wall and the outer wall of the buffer collar 13 is a sandwich layer 130.

[0049] The inner diameter of the inner ring of the buffer collar 13 is adapted to the outer diameter of the connecting groove 12. The buffer collar 13 is fitted with a sandwich 130, which is hollow and filled with air. The outer ring squeezes the sealing ring 1, first squeezing the buffer collar 13. The buffer collar 13 deforms, reducing the impact of squeezing damage to the sealing ring 1.

[0050] In this embodiment, when the double-layer anti-wear sealing ring is used, the outer ring 11 with reinforcing ribs 111 is first combined and fixed with the sealing ring 1 with ribs 140. The inner ring 10 is bonded and fixed to the inner wall of the sealing ring 1. The buffer collar 13 with interlayer 130 is fitted on the connecting groove 12. Then, the wear-resistant rubber sleeve 2 with a convex ring 21 is fitted on the sealing ring 1. The inner wall of the convex ring 21 is tightly inserted and fitted with the outer wall of the outer ring 11. The port of the groove 20 inside the wear-resistant rubber sleeve 2 is correspondingly fitted with the upper and lower surfaces of the inner ring 10, which increases the stability of the combination of the wear-resistant rubber sleeve 2 and the sealing ring 1.

[0051] The sealing ring 1 is fitted onto the object that needs to be sealed. The inner ring 10 fits tightly against the outer wall of the object. The wear-resistant rubber sleeve 2 wraps around the sealing ring 1, reducing direct contact between the outside and the sealing ring 1 and thus reducing wear and tear. The two outer rings 11 work together with the inner ring 10 to achieve double-layer sealing contact. The reinforcing ribs 111 increase the tensile strength of the outer ring of the sealing ring 1, and the reinforcing strips 140 further increase the overall tensile strength, thereby increasing the overall toughness and reducing the impact of tensile breakage.
