[0024] In order to make the personnel in the technical field better understand the present application scheme, the technical scheme in the embodiment of the present application will be described clearly and completely in combination with the drawings in the embodiment of the present application.

[0025] Embodiment one:

[0026] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a reinforced non-asbestos gasket, comprising two discs 10, a first sealing ring 11 is arranged between the two discs 10, a second sealing ring 12 is arranged inside the first sealing ring 11 between the two discs 10, sealing glue is stored between the first sealing ring 11 and the second sealing ring 12 inside the two discs 10, and the cross-sectional shape of the first sealing ring 11 and the second sealing ring 12 is as Figure 5As shown, and the first sealing ring 11 and the second sealing ring 12 are made of elastic material, after being extruded by the two circular plates 10, the first sealing ring 11 and the second sealing ring 12 will be bent relative to the inside of the two circular plates 10, which plays a storage effect on the sealing glue between the two circular plates 10, at the same time, through the elastic tension of itself, the gasket also has a certain elastic deformation ability. The outer end surface of the circular plate 10 is provided with a plurality of first annular grooves 13. The setting of the plurality of first annular grooves 13 can form a multi-ring sealing structure between the gasket and the parts that need to be sealed after the inside of each first annular groove 13 is filled with sealing glue during subsequent use of the gasket, so that the sealing effect of the gasket is higher. The inner end surface of the circular plate 10 between every two first annular grooves 13 is provided with a second annular groove 14. The inner side wall of each first annular groove 13 is provided with a plurality of glue outlets 15. Each glue outlet 15 is communicated with the first annular groove 13 and the second annular groove 14 adjacent to it. The plurality of glue outlets 15 are evenly distributed in a ring shape on the inner side wall of each first annular groove 13, so that the sealing glue between the two circular plates 10 can flow into the inside of the first annular groove 13 through each glue outlet 15 after the gasket is extruded from the outside, so that the inside of the first annular groove 13 is uniformly filled with glue.

[0027] Further, as shown in Figure 4 and Figure 5 The side of each glue outlet 15 is provided with a first through hole 16 inside the first annular groove 13. A plurality of support rods 17 are connected between the two circular plates 10. The cross-sectional shape of the first through hole 16 and the support rod 17 is as shown in Figure 4As shown, the cross section of the support rod 17 is in the shape of a rhombus, and one of the edges of the support rod 17 is opposite to the glue outlet 15. The support rod 17 is arranged to first support the two circular plates 10, so that the gasket can resist external impact to a certain extent, so that the sealant between the two circular plates 10 does not leak, thereby effectively improving the stability of the gasket during transportation and carrying. Secondly, through the shape and position of the support rod 17, the support rod 17 can play a role in distributing the sealant when the sealant is extruded from the inside of the glue outlet 15 and flows into the inside of the first annular groove 13, thereby further making the sealant flowing into the inside of the first annular groove 13 more uniform, and further improving the sealing performance of the gasket during use. The two ends of each support rod 17 are connected with the first through hole 16 adjacent thereto, and the length of each support rod 17 does not exceed the total thickness of the two circular plates 10, so that when the gasket is installed and used, the support rods 17 do not form a support on both sides of the gasket during the process of extrusion and thinning of the gasket, so that the sealant between the two circular plates 10 can more smoothly fill the inside of the plurality of first annular grooves 13.

[0028] Further, as shown in the drawings, Figure 6 Each first annular groove 13 and second annular groove 14 is provided with a plurality of partitions 18, and the plurality of partitions 18 can further increase the strength of each circular plate 10. The side wall of each partition 18 is provided with a second through hole 19, and the second through hole 19 can effectively increase the flowability of the sealant on both sides of the partition 18, thereby improving the sealing performance of the gasket.

[0029] When the gasket is used, it only needs to be installed between two articles that need to be sealed, and other external devices are used to extrude the two articles that need to be sealed, so that the upper and lower end faces of the gasket are extruded, and then the sealant between the two circular plates 10 flows into the inside of the first annular groove 13 from the plurality of glue outlets 15. During this process, the two ends of the support rod 17 will move into the inside of the first annular groove 13 adjacent thereto, so that the glue flowing into the inside of the first annular groove 13 from the glue outlet 15 is distributed under the action of the support rod 17, and when the glue distribution on both sides of the partition 18 in the inside of each first annular groove 13 is not uniform, it will further flow through the second through hole 19, thereby improving the sealing performance of the entire gasket between the two articles.

[0030] Example two:

[0031] On the basis of example one, further examples are made, as shown in the drawings, Figure 1As shown, the outer end surface of each wafer 10 is provided with a glue absorbing pad 20, which is made of low-density high-strength water-absorbing material, such as nanocellulose material, and can effectively increase the tight connection between the outer end surface of the wafer 10 and the sealant, thereby further increasing the sealing performance of the gasket.

[0032] As used in the specification and claims, certain terminology is used to refer to certain components. One of skill in the art will understand that different manufacturers can refer to the same component using different terminology. The specification and claims do not serve as a means to distinguish components based on the difference in terminology, but rather serve as a means to distinguish components based on the difference in functionality. As used throughout the specification and claims, "comprising" is intended to be an open term, thus comprising, means "including, but not limited to." "Substantially" means within acceptable manufacturing tolerances, and one of skill in the art would understand that the technical problem can be solved within acceptable manufacturing tolerances, and the technical effect is substantially achieved.

[0033] It should be noted that the terms "comprising," "including," and "having" or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a process, product, article, composition, or apparatus that comprises a list of elements is not necessarily limited to only those elements but can include other elements not expressly listed or inherent to such process, product, article, composition, or apparatus. In other words, unless expressly stated to the contrary, the process, product, article, composition, or apparatus that "comprises" or "has" or "including" one or more elements of a list of elements does not exclude other elements of the same process, product, article, composition, or apparatus.

[0034] The foregoing description illustrates and describes the only preferred embodiments of the application. However, it is to be understood that the application is not limited to the precise embodiments, and that it can be practiced with various modifications, alterations, and permutations without deviating from the spirit and scope of the application. Accordingly, the application is not limited to the above-described embodiments, but is intended to cover any and all modifications and equivalents.
