Abstract
Description
Technical Field
[0001] The utility model relates to a sealing ring with multiple protections. Background Art
[0002] In the engineering field, a sealing ring is usually placed on a part (such as a pipe body) to seal the gap between the sealing ring and the part (such as the pipe body).
[0003] Traditional sealing rings usually only have one sealing inner ring, and their sealing effect is greatly affected by the fluctuation of the part diameter, which can easily lead to unstable sealing performance between the sealing ring and the part (such as the pipe body) or fail to achieve the ideal effect. Utility Model Content
[0004] The purpose of the utility model is to provide a sealing ring with multi-layer sealing and good sealing effect and multiple protections.
[0005] The purpose of this utility model is achieved in this way:
[0006] A multi-protection sealing ring comprises a sealing ring body, wherein the inner wall of the sealing ring body is provided with flexible contact teeth at intervals along the axial direction thereof, and the tips of the flexible contact teeth face the inner cavity of the sealing ring body.
[0007] The multi-protection sealing ring is provided with flexible contact teeth at intervals along its axial direction to form a multi-layer seal. When the multi-protection sealing ring is placed on a part (such as a pipe body), in a low-pressure environment, a single layer of flexible contact teeth seal can already play a sealing role, while the multi-layer seal is equivalent to a combination of multiple sealing rings, and each additional layer of seal will increase the sealing coefficient, so a multi-layer seal is used.
[0008] The sealing coefficient is greatly increased, and this design can significantly improve the sealing performance.
[0009] Due to the flexible contact teeth design, the multi-protection seal can adapt to different pipe diameters and shapes. Even when the pipe diameter changes, the flexible contact teeth can ensure a stable sealing effect. This adaptability can meet the changing needs of pipes in industrial applications and ensure a consistent sealing effect.
[0010] The optimized sealing design can significantly reduce the risk of leakage. Through the effective sealing of the flexible contact teeth, the multi-protection seal can prevent liquid or gas from leaking through the gap between the multi-protection seal and the component (such as the pipe body).
[0011] The purpose of the utility model can also be solved by the following technical measures:
[0012] Furthermore, the flexible contact teeth swing along the axial direction of the sealing ring body with the connection point thereof as the rotation center.
[0013] The flexible contact teeth can deform axially outward to adapt to changes in the outer diameter and shape of the mating parts. This design allows the part diameter to fluctuate within a range of 6mm while still maintaining effective sealing performance. This wide adaptability enables the multi-protection sealing ring to still work reliably in the face of large fluctuations in part diameter or irregular cross-sections, reducing the risk of sealing failure due to changes in part size.
[0014] Even if the tube moves or experiences minor vibrations during operation, the flexible contact teeth can flexibly adjust their position to maintain close contact with the outer wall of the tube. This capability effectively prevents liquid or gas leakage that may occur during movement, improving sealing effectiveness and system safety.
[0015] Furthermore, the flexible contact teeth at the same height form a sealing inner ring.
[0016] The flexible contact teeth at the same height inside the multi-protection sealing ring form a sealing inner ring, which can effectively surround and seal the contacting parts (such as the pipe body).
[0017] Furthermore, the inner diameter of the sealing inner ring is variable, and the deformation range of the inner diameter of the sealing inner ring is within 6 mm.
[0018] This design ensures that the multi-protected seal can provide stable and efficient sealing on contact parts of different diameters, both when stationary and when the contact parts are moving.
[0019] The inner diameter of the sealing ring can be adjusted within a 6mm deformation range. This design allows the multi-protection seal to adapt to changes in the inner diameter of the contacting parts, maintaining a stable sealing effect regardless of dimensional fluctuations caused by manufacturing tolerances, temperature changes, or operating conditions. This high degree of adaptability ensures the reliability of the multi-protection seal in a variety of complex industrial applications.
[0020] The deformability of the inner ring effectively reduces the risk of leakage. Its flexible contact teeth allow the inner ring to adjust and maintain a tight seal regardless of changes in the diameter of the contacting parts. This design feature is particularly important in applications requiring high reliability and safety.
[0021] Furthermore, outer rings are arranged at intervals on the outer wall of the sealing ring body, and a sealing ring retaining groove is formed between the outer rings.
[0022] A sealing ring retaining groove is formed between the outer rings on the outer wall of the sealing ring body. This structure not only enhances the stability of the connection between the multi-protected sealing ring and external components, but also ensures that sealing elements such as sealing rings or O-rings can be safely and reliably embedded within it. The cooperation between the outer ring and the sealing ring retaining groove firmly secures the sealing element to the multi-protected sealing ring, effectively preventing it from moving or falling off during use, thereby ensuring the durability and reliability of the seal.
[0023] Furthermore, the outer ring is provided with a boss for facilitating connection and sealing with other sealing members.
[0024] A boss is provided on the outer ring of the multi-protection sealing ring, and the boss allows the multi-protection sealing ring to be effectively sealed and connected with adjacent multi-protection sealing rings or other sealing components.
[0025] Furthermore, the boss is provided with a contact slope.
[0026] The contact bevel is connected to other sealing parts by extrusion and interference fit to achieve sealing. This design improves the stability of the seal.
[0027] Furthermore, the sealing ring body, the flexible contact teeth, the outer ring and the boss are integrally formed.
[0028] The one-piece design of the seal body, flexible contact teeth, outer ring and boss means these components are produced as a single part, requiring no additional assembly steps, thereby reducing manufacturing costs and improving production efficiency.
[0029] Furthermore, the sealing ring body, the flexible contact teeth, the outer ring and the boss are all made of plastic.
[0030] The sealing ring body, flexible contact teeth, outer ring and boss are made of plastic material. The flexibility of the plastic material enables the multi-protection sealing ring to better adapt to contact parts of different shapes and sizes and maintain stable sealing performance.
[0031] The beneficial effects of the utility model are as follows:
[0032] In the present utility model, the multi-protection sealing ring is provided with flexible contact teeth at intervals along its axial direction to form a multi-layer seal. When the multi-protection sealing ring is placed on a part (for example, a pipe body), under a low-pressure environment, a single-layer flexible contact tooth seal is sufficient to perform a sealing function, while the multi-layer seal is equivalent to a combination of multiple sealing rings, and each additional layer of seal will increase the sealing coefficient. Therefore, the use of multi-layer seals greatly increases the sealing coefficient. This design can significantly improve the sealing performance.
[0033] Due to the design characteristics of the flexible contact teeth, the multi-protection sealing ring of this utility model can adapt to different pipe diameters and shapes. Even when the pipe diameter changes, the flexible contact teeth can ensure a stable sealing effect. This adaptability can meet the needs of changing pipes in industrial applications and ensure a consistent sealing effect.
[0034] In the present invention, the flexible contact teeth can deform axially outward to adapt to changes in the outer diameter and shape of the mating parts. This design allows the part diameter to fluctuate within a range of 6 mm while still maintaining effective sealing performance. This wide adaptability enables the multi-protection sealing ring to still work reliably in the face of large fluctuations in part diameter or irregular cross-sections, reducing the risk of sealing failure due to changes in part size.
[0035] In the utility model, the contact bevel realizes sealing by extrusion and interference fit at the position where it connects with other sealing parts. This design allows the multi-protection sealing ring to be effectively sealed and connected with adjacent multi-protection sealing rings or other sealing parts, thereby increasing the stability of the seal.
