Description

Technical Field

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

[0002] High-pressure valves play a vital role in various industrial applications. They are usually used to control the flow of high-pressure fluids. In these applications, the sealing performance of the valve is directly related to the safety and reliability of the system. Traditional high-pressure valve seals usually consist of an O-ring and two retaining rings to achieve fluid sealing.

[0003] Although conventional seal designs provide adequate sealing performance in certain applications, they have some inherent limitations:

[0004] 1) Installation complexity: The combination of O-rings and retaining rings requires precise installation and positioning, which can be time-consuming and error-prone in actual operation.

[0005] 2) Service life: Since traditional sealing rings are composed of multiple independent components, these components are easily damaged under high pressure and wear environments, resulting in a decrease in sealing performance, thereby shortening the service life of the sealing ring.

[0006] 3) High pressure resistance: Under high pressure environment, traditional sealing rings may not be able to provide continuous and stable sealing effect due to material limitations or structural instability.

[0007] 4) Wear resistance: Frequent operation and flushing of high-pressure fluids may cause wear of traditional sealing rings, further affecting their sealing performance.

[0008] 5) Maintenance costs: Since traditional seals have a shorter service life, they need to be replaced more frequently, which increases maintenance costs and downtime.

[0009] In view of the above limitations, the prior art urgently needs an improved sealing ring design, which should be able to simplify the installation process, increase the service life of the sealing ring, and maintain stable sealing performance under high pressure and wear environments. Summary of the invention

[0010] In order to solve the above problems, the utility model provides a sealing ring with particularly outstanding performance under high pressure and wear environment.

[0011] In order to achieve the above-mentioned purpose, the sealing ring designed in the utility model includes a sealing ring body, and a sealing flat gasket is respectively provided on both axial sides of the sealing ring body. The two sealing flat gaskets and the sealing ring body are an integrally formed structure. The outer diameter of the sealing ring body is larger than the outer diameter of the sealing flat gasket, and the two sealing flat gaskets are parallel and identical to each other.

[0012] In order to avoid a possible gap between the sealing ring body and the sealing flat gasket, annular planes matching the sealing flat gasket are provided on both axial sides of the sealing ring body.

[0013] In order to provide better pressure resistance, the cross section of the sealing ring body is arc-shaped.

[0014] A further solution is that the inner diameter of the sealing ring body is larger than the inner diameter of the sealing flat gasket.

[0015] In order to reduce the risk of cracks, the edge portion of the sealing ring body and the edge portion of the sealing flat gasket have a smooth transition.

[0016] In order to provide consistent and reliable sealing performance, the ratio (H / S) of the sum of the thicknesses of the two sealing flat gaskets and the sealing ring body and the difference (S) between the outer diameter of the sealing ring body and the outer diameter of the sealing flat gasket is 4.6-5.5.

[0017] The sealing ring designed by the utility model enhances the durability of the sealing ring and prolongs its service life through the integrated molding of the sealing ring body and the sealing flat gasket, and performs well in high-pressure and wear environments. In addition, this structural optimization significantly improves the high-pressure resistance of the sealing ring, reduces the risk of leakage, and optimizes the wear resistance, and can maintain a low wear rate even in the face of continuous flushing of high-pressure fluids. These improvements directly lead to a reduction in maintenance costs, because the sealing ring is more durable, requires less maintenance and replacement, and can show good environmental adaptability to adapt to extreme temperatures and chemically corrosive conditions, thereby greatly expanding its potential application range.

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example 1.

[0023] like Figure 1-3As shown, the sealing ring described in this embodiment includes a sealing ring body 1, and a sealing flat gasket 2 is respectively provided on both axial sides of the sealing ring body 1. The two sealing flat gaskets 2 and the sealing ring body 1 are an integrally formed structure. The outer diameter of the sealing ring body 1 is larger than the outer diameter of the sealing flat gasket 2, and the two sealing flat gaskets 2 are parallel and identical to each other.

[0024] In specific implementation, the sealing ring body 1 and the sealing flat gasket 2 are made of a synthetic rubber material with specific elasticity (such as nitrile rubber, fluororubber) to meet the sealing requirements under high-pressure environments, and the sealing ring body 1 and the sealing flat gasket 2 are manufactured into an integrated molding structure through injection molding and other processes to ensure the integrity and consistency of the sealing ring.

[0025] In addition, the outer diameter of the sealing ring body 1 is slightly larger than the outer diameter of the sealing flat gasket 2. This design is to ensure that the sealing flat gasket 2 can form appropriate compression on the outer edge of the sealing ring body 1 (refer to Figure 1 , protruding from the outer edge of the sealing ring body 1), thereby providing a better sealing effect during installation. At the same time, the two sealing flat gaskets 2 are not only parallel to each other, but also have exactly the same size. Such a symmetrical design helps to maintain consistent sealing performance in a symmetrical installation environment, ensuring that the sealing ring can provide a balanced and reliable sealing effect under various working conditions.

[0026] In some embodiments, Figure 3 As shown, in order to avoid a possible gap between the sealing ring body 1 and the sealing flat gasket 2 , annular planes matching the sealing flat gasket 2 are provided on both axial sides of the sealing ring body 1 .

[0027] In this embodiment, the matching design of the annular plane (not shown in the figure) can avoid the formation of unnecessary gaps / notches between the sealing ring body 1 and the sealing flat gasket 2, ensure good contact between the sealing flat gasket 2 and the sealing ring body 1, and enhance the sealing effect, especially in dynamic or high-pressure applications. In addition, the annular plane helps to evenly distribute the contact pressure generated by the sealing flat gasket 2, reduce local stress concentration, and extend the service life of the sealing ring.

[0028] In some embodiments, Figure 3 As shown, in order to provide better pressure resistance, the cross section of the sealing ring body 1 is arc-shaped. In this way, the arc-shaped cross section can have better elastic recovery ability, which means that the sealing ring can better restore its original shape after being compressed and maintain long-term sealing performance.

[0029] In this embodiment, if Figure 3 As shown, the inner diameter of the sealing ring body 1 is larger than the inner diameter of the sealing flat gasket 2. Figure 3The inner diameter of the sealing ring body 1 is the middle position of the arc-shaped inner wall surface of the sealing ring body 1, that is, the arc-shaped cross-section of the sealing ring body 1 combined with the design that the inner diameter of the sealing ring body 1 is larger than the inner diameter of the sealing flat gasket 2 can form a concave cavity on the inner wall of the sealing ring, which can enhance the stability of the sealing ring during installation, and also help to improve the sealing effect and reduce the risk of medium leakage.

[0030] In some embodiments, Figure 1 and Figure 3 As shown, in order to reduce the risk of cracks, a smooth transition is formed between the edge of the sealing ring body 1 and the edge of the sealing flat gasket 2. By adopting a smooth transition design, the connection gap between the sealing ring body 1 and the sealing flat gasket 2 can be effectively reduced, because these gaps are often the initial positions of crack formation, thereby reducing the risk of cracks and fractures, and significantly improving its durability and reliability during use.

[0031] In some embodiments, Figure 1 and Figure 3 As shown, in order to provide consistent and reliable sealing performance, the ratio (H / S) of the sum of the thicknesses of the two sealing gaskets 2 and the sealing ring body 1 and the difference (S) between the outer diameter of the sealing ring body 1 and the outer diameter of the sealing gasket 2 is 4.6-5.5.

[0032] When implementing it, refer to Figure 3 The difference between the outer diameter (R1) of the sealing ring body 1 and the outer diameter (R2) of the sealing flat gasket 2 is S (R1-R2), which is multiplied by the thickness (H) of the sealing ring body (S=HP), where the value of P is between 4.6 and 5.5, ensuring that the sealing ring can provide consistent and reliable sealing effect under various working conditions.

[0033] The sealing ring provided in this embodiment has enhanced durability and prolonged service life through the integrated molding of the sealing ring body and the sealing flat pad, and performs well in high-pressure and wear environments. In addition, this structural optimization significantly improves the high-pressure resistance of the sealing ring, reduces the risk of leakage, and optimizes the wear resistance, and can maintain a low wear rate even in the face of continuous flushing of high-pressure fluids. These improvements directly lead to a reduction in maintenance costs, because the sealing ring is more durable, requires less maintenance and replacement, and can show good environmental adaptability to adapt to extreme temperatures and chemically corrosive conditions, thereby greatly expanding its potential application range.
