Description

Technical Field

[0001] This utility model relates to the field of sealing ring technology, and in particular to an elastic O-ring. Background Technology

[0002] An O-ring is a circular ring-shaped seal primarily used to prevent the leakage of liquids or gases. Made of elastic materials (such as rubber and plastics), it is widely used in static and dynamic sealing applications of various mechanical equipment due to its simple structure, ease of use, and excellent sealing performance. O-rings possess properties such as high pressure resistance, high and low temperature resistance, and chemical corrosion resistance, making them a common sealing element in industrial, automotive, and chemical industries. Existing O-rings primarily rely on the elasticity of a single material to achieve a sealing effect. During operation, they deform to adhere to the contact surface, preventing fluid or gas leakage. However, existing O-rings are prone to material aging or performance degradation due to heat conduction under high-temperature conditions, lack sufficient structural strength under high-pressure conditions, and suffer wear failure during long-term operation in frictional environments, even breaking during mechanical stretching, thus limiting the application range of O-rings. To address these issues, those skilled in the art have proposed an elastic O-ring to solve these problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides an elastic O-ring, which aims to improve the existing O-rings that are prone to material aging or performance degradation due to heat conduction under high temperature conditions, lack sufficient structural strength under high pressure conditions, and suffer wear failure during long-term operation in frictional environments, or even breakage during mechanical stretching.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an elastic O-ring, comprising an O-ring body, a sealing and reinforcing ring disposed on the outside of the O-ring body, a protective sleeve disposed on the outside of the sealing and reinforcing ring, a plurality of protrusions disposed on the outside of the sealing and reinforcing ring, and an installation groove provided on the inner side of the protective sleeve.

[0005] Furthermore, the protective collar has multiple fixing grooves inside, and each fixing groove is provided with a reinforcing metal block.

[0006] Furthermore, the O-ring body is made of silicone rubber, fluororubber, or other highly elastic materials, which have excellent sealing performance and corrosion resistance.

[0007] Furthermore, the protrusion is disposed on the outer peripheral surface of the O-ring body and mates with the mounting groove to enhance the sealing and installation stability of the O-ring.

[0008] Furthermore, the sealing reinforcement ring is made of polytetrafluoroethylene or metal and is embedded in the mounting groove to improve the sealing performance and high pressure resistance of the O-ring.

[0009] Furthermore, the surface is provided with a wear-resistant layer, a heat-resistant layer is provided inside the wear-resistant layer, a heat insulation layer is provided inside the heat-resistant layer, and a tensile layer is provided inside the heat insulation layer.

[0010] Furthermore, the wear-resistant layer is made of a wear-resistant ceramic coating, and the tensile layer is made of high-strength fiber material.

[0011] Furthermore, the heat-resistant layer is made of polyimide material, and the heat-insulating layer is made of aluminum oxide coating.

[0012] This utility model has the following beneficial effects: 1. In this utility model, the high elasticity of the O-ring body achieves sealing. Under pressure, it deforms and fits the contact surface. The sealing reinforcement ring enhances the pressure resistance, and the protective ring protects the sealing component from wear and corrosion. The reinforcing metal block in the fixing groove improves the structural strength. The protrusion cooperates with the mounting groove to enhance operational stability and prevent loosening and sealing failure. It achieves the technical effects of high elasticity sealing, high pressure resistance, corrosion resistance and stable operation. Compared with the problem of insufficient sealing performance in the prior art, it solves the problem of easy failure under complex working conditions.

[0013] 2. In this utility model, the wear-resistant layer on the surface of the protective ring improves the durability of the O-ring in the friction environment, the heat-resistant layer isolates the high temperature and protects the O-ring body from damage, the heat insulation layer blocks heat transfer and provides a stronger heat insulation effect, and the tensile layer enhances the structural strength, thus achieving the technical effect of enhancing wear resistance, heat resistance, heat insulation and tensile strength.

[0016] 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.

[0017] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of an elastic O-ring, comprising an O-ring body 5, which is used to achieve a sealing effect and prevent media leakage by deforming and fitting the contact surface. A sealing reinforcement ring 3 is provided on the outside of the O-ring body 5, which is used to enhance the sealing performance of the O-ring under high pressure. A protective sleeve 1 is provided on the outside of the sealing reinforcement ring 3, which is used to protect the internal sealing structure from external wear and chemical corrosion. Multiple protrusions 2 are provided on the outside of the sealing reinforcement ring 3, which are used to cooperate with the mounting groove 10 to increase operational stability. The inner side of the protective sleeve 1 is provided with a mounting groove 10, which is used to install the sealing reinforcement ring 3.

[0018] Reference Figure 2 and Figure 3 The protective sleeve 1 has multiple fixing grooves 4 inside, which are used to enhance structural stability. Each fixing groove 4 contains a reinforcing metal block to improve the impact resistance and durability of the protective sleeve 1. The O-ring body 5 is made of silicone rubber, fluororubber, or other highly elastic materials, possessing excellent sealing performance and corrosion resistance, and effectively adapting to complex working conditions such as high temperature and high pressure. The protrusion 2 is located on the outer circumferential surface of the O-ring body 5 and mates with the mounting groove 10 to enhance the sealing and installation stability of the O-ring, and effectively prevent slippage or detachment during installation. The sealing reinforcement ring 3 is made of polytetrafluoroethylene or metal and embedded in the mounting groove 10 to improve the sealing performance and high pressure resistance of the O-ring, while providing additional wear protection during long-term use.

[0019] Reference Figure 1 and Figure 4The protective collar 1 has a wear-resistant layer 6 on its surface, which is made of wear-resistant ceramic coating and can effectively improve the wear resistance of the surface. The inner side of the wear-resistant layer 6 is provided with a heat-resistant layer 7, which is made of polyimide material and can maintain stability in high temperature environment. The inner side of the heat-resistant layer 7 is provided with a heat insulation layer 8, which is made of alumina coating and can block heat transfer, reduce the overall thermal conductivity, and improve the thermal protection performance. The inner side of the heat insulation layer 8 is provided with a tensile layer 9, which is made of high-strength fiber material and has excellent tensile strength, which can improve the mechanical properties of the overall structure and prevent deformation damage.

[0020] Working principle: When using this device, the high elasticity of the O-ring body 5 achieves a sealing effect between the equipment. The O-ring body 5 deforms under pressure and fits tightly with the contact surface, thereby preventing the leakage of fluid or gas. Under the action of the sealing reinforcement ring 3, the O-ring's pressure resistance under high pressure environment is enhanced. It provides additional sealing pressure by embedding in the mounting groove 10, avoiding the decline in sealing performance due to long-term use. The protective sleeve 1 plays a protective role by covering the outside of the sealing reinforcement ring 3, preventing external wear or chemical corrosion of the sealing components. The reinforcing metal block in the fixing groove 4 further enhances the structural strength of the protective sleeve 1. The protrusion 2 increases the stability of the O-ring during operation by cooperating with the mounting groove 10, preventing loosening and sealing failure caused by vibration or mechanical action. The wear-resistant layer 6 on the surface of the protective ring 1 improves the service life of the O-ring in long-term friction environments. At the same time, the heat-resistant layer 7 protects the O-ring body 5 from high-temperature damage by isolating the O-ring from the conduction of high temperature environment. The heat insulation layer 8 further prevents heat transfer and provides better heat insulation effect for the O-ring body 5. The tensile layer 9 increases the strength of the overall structure and effectively prevents the O-ring from breaking when subjected to large mechanical tension or pressure. Finally, the elastic O-ring achieves long-term sealing and reliable operation in complex environments such as high temperature, high pressure and strong friction.
