Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sealing gaskets, and particularly relates to a sealing gasket with earthquake resistance and high temperature resistance functions. Background Art
[0002] Large pipelines are widely used in many fields, including but not limited to drainage, water supply, oil transportation, power transmission, etc. These pipelines usually have a relatively large pipe diameter to meet the needs of specific projects or systems. A pipeline sealing gasket is a soft material placed between two large pipeline connectors to fill the gap between them and prevent fluid or gas leakage. Therefore, we introduce a sealing gasket with earthquake resistance and high temperature resistance functions. Content of the Utility Model
[0003] The main purpose of the utility model is to provide a sealing gasket with earthquake resistance and high temperature resistance functions, which can effectively solve the problems in the background art.
[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0005] A sealing gasket with earthquake resistance and high temperature resistance functions, including a sealing gasket body. Both the middle part of the front end and the middle part of the rear end of the sealing gasket body are fixedly connected with two extension parts. Both the front end and the rear end of the sealing gasket body are fixedly connected with two convex strips. The four convex strips are grouped in pairs, and the two extension parts are respectively located within the two groups of convex strips. The sealing gasket body, the two extension parts and the two convex strips are of an integrally formed structure.
[0006] By adopting the above technical solution: The sealing gasket body and the two extension parts are both made of metal graphite composite materials.
[0007] Preferably, a first metal inner ring is fixedly connected inside the sealing gasket body, and a second metal inner ring is fixedly connected to the inner wall of the first metal inner ring.
[0008] By adopting the above technical solution: The first metal inner ring and the second metal inner ring can support the sealing gasket body and the two extension parts, so that the three can maintain rigidity even at high temperatures.
[0009] Preferably, the width of the second metal inner ring is greater than the width of the first metal inner ring.
[0010] Preferably, the second metal inner ring is located within the two extension parts.
[0011] By adopting the above technical solution: The second metal inner ring can support the two extension parts simultaneously.
[0012] Preferably, inclined surfaces are provided on the outer surfaces of the two extension parts.
[0013] By adopting the above technical solution: the inclined surface enables the extension part to fit the inner wall of the pipeline, improving stability.
[0014] Preferably, the two extension parts are symmetrically arranged.
[0015] The utility model has the following beneficial effects:
[0016] 1. In the utility model, by arranging extension parts at the front end and the rear end of the sealing gasket body, after the two extension parts contact the two pipelines, the two extension parts will respectively be stuck into the two pipelines. Since inclined surfaces are provided on the outer surfaces of the two extension parts, the stability of being stuck in is improved, and further the stability of the connection between the gasket and the two pipelines is improved;
[0017] 2. In the utility model, by arranging a first metal inner ring in the sealing gasket body, and a second metal inner ring is fixedly connected to the inner wall of the first metal inner ring. Since the second metal inner ring is located inside the two extension parts, the second metal inner ring supports the two extension parts, and the first metal inner ring supports the sealing gasket body, so that the overall rigidity of the sealing gasket is improved. When the whole gasket is under high temperature and high pressure and the medium pressure changes sharply, under the support of the first metal inner ring and the second metal inner ring, the sealing gasket body can always maintain sufficient rigidity and strength.

[0025] Please refer to Figures 1-3 , the present utility model provides a technical solution:
[0026] A sealing gasket with earthquake resistance and high temperature resistance functions, including a sealing gasket body 1. Two extension parts 3 are fixedly connected to the middle of the front end and the middle of the rear end of the sealing gasket body 1 respectively. Two convex strips 2 are fixedly connected to the front end and the rear end of the sealing gasket body 1 respectively. The four convex strips 2 are grouped in pairs, and the two extension parts 3 are respectively located inside the two groups of convex strips 2. The sealing gasket body 1, the two extension parts 3 and the two convex strips 2 are of an integrally formed structure.
[0027] In this embodiment, a first metal inner ring 11 is fixedly connected inside the sealing gasket body 1, and a second metal inner ring 12 is fixedly connected to the inner wall of the first metal inner ring 11; the width of the second metal inner ring 12 is greater than the width of the first metal inner ring 11; the second metal inner ring 12 is located inside the two extension parts 3; inclined surfaces 31 are provided on the outer surfaces of the two extension parts 3; the two extension parts 3 are symmetrically arranged.
[0028] Through the above solution: the first metal inner ring 11 supports the sealing gasket body 1, and the second metal inner ring 12 supports the two extension parts 3. Under the support of the first metal inner ring 11 and the second metal inner ring 12, when the gasket is subjected to high temperature and vibration, it can always maintain rigidity and avoid deformation, so as to adapt to the use of large pipelines.
[0029] It should be noted that the present utility model describes a sealing gasket with earthquake resistance and high temperature resistance functions. By adding extension parts 3 at the front and rear ends of the sealing gasket body 1, these extension parts 3 automatically embed into the interior of the pipeline when the sealing gasket body 1 contacts the pipeline. Utilizing the design of the inclined surface parts 31 on their outer surfaces, the stability of the embedding and the overall firmness of the connection between the sealing gasket body 1 and the pipeline are significantly enhanced. In addition, a first metal inner ring 11 is arranged inside the sealing gasket body 1, and a second metal inner ring 12 is fixedly connected inside the first metal inner ring 11. The second metal inner ring 12 is located within the two extension parts 3, forming an effective support for the extension parts 3. At the same time, the first metal inner ring 11 directly supports the sealing gasket body 1, significantly improving the overall rigidity of the sealing gasket. This structure ensures that when facing the challenges of high temperature and high pressure environments and vibrations caused by pressure, the sealing gasket body 1 can maintain excellent rigidity and strength under the dual support of the first metal inner ring 11 and the second metal inner ring 12, ensuring that the sealing performance is not affected.
