Description

Technical Field

[0001] This utility model belongs to the field of sealing gasket technology, and in particular relates to a combined sealing gasket. Background Technology

[0002] A gasket is a critical sealing element used in mechanical equipment, piping systems, or other joints. Its main function is to fill the gap between the mating surfaces and prevent the leakage of fluids (such as gases or liquids) by compression.

[0003] Traditional sealing gaskets are prone to deformation or deviation during long-term operation, which reduces their stability during operation, and they also have a short service life and poor practicality. Utility Model Content

[0004] The purpose of this invention is to provide a combined sealing gasket to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A combined sealing gasket includes a support ring, on both the upper and lower sides of the support ring, gaskets are detachably connected, and multiple sealing edges are provided on the side of the upper and lower gaskets that are far apart from each other. Grooves are provided on both the upper and lower sides of the support ring, and protrusions corresponding to the grooves are provided on the side of the gaskets that are far away from the sealing edges.

[0006] Preferably, the outer diameter and inner diameter of the washer are equal to the outer diameter and inner diameter of the support ring.

[0007] Preferably, an annular groove is provided in the middle part of both the outer and inner sidewalls of the support ring.

[0008] Preferably, the tab is made of metal, and the size of the tab matches the size of the groove.

[0009] Preferably, both the groove and the protrusion are annular structures.

[0010] Preferably, the surface of the support ring is provided with four limiting holes arranged in a circumferential array on one side of the groove, and the gasket is provided with four limiting posts that correspond one-to-one with the limiting holes on the side away from the sealing edge. The diameter of the limiting posts is equal to the diameter of the limiting holes, and the sum of the lengths of two limiting posts is less than the length of the limiting holes.

[0011] Preferably, the sealing edge is an annular structure, and the diameters of the plurality of sealing edges decrease sequentially.

[0012] The combined sealing gasket of this utility model has the following advantages:

[0013] 1. By providing annular grooves on the inner and outer walls of the support ring, this utility model creates a buffer space when the sealing gasket is compressed, resulting in a tighter and more reliable contact between the sealing gasket and the object, thus improving the sealing effect. Furthermore, the protrusions provide rigid support, effectively preventing the sealing gasket from deforming due to excessive compression, thereby significantly extending its service life.

[0014] 2. This utility model utilizes the cooperation between the limiting post and the limiting hole to ensure that when installing the washer and the support ring, the limiting post inserts into the limiting hole, thereby limiting the movement between the washer and the support ring. This effectively prevents rotation between the washer and the support ring, ensuring the reliability of the structure. Furthermore, by setting the washer to connect with the support ring through the protrusion, the limiting post, the groove, and the limiting hole, it is easy to assemble and disassemble the washer and the support ring. This allows for individual disassembly and replacement of the washer or the support ring when it is damaged, greatly saving costs and demonstrating strong practicality.

[0015] 3. By setting multiple sealing edges, multiple sealing layers are formed between the sealing gasket and the object surface, thereby greatly improving the sealing effect. Attached Figure Description

[0026] To better understand the purpose, structure, and function of this utility model, a combined sealing gasket of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] like Figure 1-3As shown, this utility model discloses a combined sealing gasket, comprising a support ring 1. Gaskets 2 are detachably connected to both the upper and lower sides of the support ring 1. The outer and inner diameters of the gaskets 2 are equal to those of the support ring 1, ensuring a tight fit between the inner and outer rings of the gaskets 2 and the inner and outer rings of the support ring 1. Annular grooves 3 are provided in the middle of both the outer and inner walls of the support ring 1. These grooves provide a buffer space during compression, resulting in a tighter and more reliable contact between the sealing gasket and the object, thus improving the sealing effect.

[0028] Multiple sealing edges 4 are provided on the opposite sides of the upper and lower gaskets 2. The sealing edges 4 are annular structures, and the diameters of the multiple sealing edges 4 decrease sequentially. The multiple sealing edges 4 form multiple sealing layers between the gasket and the object surface, thereby greatly improving the sealing effect. Grooves 5 are provided on both the upper and lower sides of the support ring 1. The side of the gasket 2 away from the sealing edge 4 is provided with protrusions 7 corresponding to the grooves 5. The protrusions 7 are made of metal, and their size matches the size of the grooves 5. Both the grooves 5 and the protrusions 7 are annular structures. With the protrusions 7, when the support ring 1 is compressed to a certain extent, the upper and lower protrusions 7 provide rigid support, effectively preventing the gasket from deforming due to excessive compression, thus greatly extending the service life of the gasket.

[0029] The surface of the support ring 1 has four limiting holes 6 arranged in a circular array on one side of the groove 5. The side of the gasket 2 away from the sealing edge 4 has four limiting posts 8 that correspond one-to-one with the limiting holes 6. The diameter of the limiting post 8 is equal to the diameter of the limiting hole 6, and the sum of the lengths of the two limiting posts 8 is less than the length of the limiting hole 6. Through the cooperation between the limiting post 8 and the limiting hole 6, when the gasket 2 and the support ring 1 are installed, the limiting post 8 will be inserted into the limiting hole 6, thereby limiting the gasket 2 and the support ring 1. This can effectively prevent the phenomenon of rotation between the gasket 2 and the support ring 1, ensuring the reliability of the structure. Moreover, since the sum of the lengths of the two limiting posts 8 is less than the length of the limiting hole 6, it will not interfere with the compression and buffering of the support ring 1. Furthermore, by setting the washer 2 to be connected to the groove 5 and the limiting hole 6 of the support ring 1 through the protrusion 7 and the limiting post 8, it is convenient to assemble and disassemble the washer 2 and the support ring 1. Thus, when the washer 2 or the support ring 1 is damaged, it can be disassembled and replaced separately, which greatly saves costs and is highly practical.

[0030] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
