Graphite composite gasket structure

Abstract

The utility model relates to a graphite composite gasket structure which comprises a main body unit, a first outer reinforcing unit, a second outer reinforcing unit, a first inner reinforcing unit and a second inner reinforcing unit. The reinforcing structure has the advantages that the main body unit, the first outer reinforcing unit, the second outer reinforcing unit, the first inner reinforcing unit and the second inner reinforcing unit are matched for use and connected with the main body unit in a clamping mode, and compared with adhesive connection, the clamping structure is more stable. Under complex working conditions of equipment vibration, temperature change and the like, the clamping position is not prone to loosening, and it is ensured that the reinforcing unit and the main body unit are tightly combined all the time. All the reinforcing units wrap and reinforce the main body unit from the inner side and the outer side in an all-around mode. The structural design can effectively disperse the pressure applied to the main body unit during the operation of the equipment, avoids the damage of the gasket caused by overlarge local stress, and improves the overall strength of the main body unit.

Description

Technical Field

[0001] This utility model relates to the technical field of graphite gaskets, and in particular to a graphite composite gasket structure. Background Technology

[0002] Graphite gaskets are sealing elements widely used in industry and daily life, primarily made from natural graphite through special processing. They are soft and elastic, possess excellent chemical stability, and can withstand the erosion of various acids, alkalis, and other chemical media. In appearance, they are typically thin sheets, deep in color like ink, with a smooth, flat surface and neat edges. They come in various shapes, commonly round or square, and can be customized to meet specific sealing requirements.

[0003] In the industrial sector, graphite gaskets are commonly used for sealing connections in pipes, valves, pumps, and other equipment. For example, in chemical production, facing high-temperature, high-pressure, and highly corrosive media, graphite gaskets can tightly seal the connection, effectively preventing leakage and ensuring production safety and stability. In households, they are also used to seal some gas appliances, ensuring safe gas usage and preventing leaks that could cause hazards. Due to their excellent high-temperature resistance, they maintain a stable sealing effect even in high-temperature environments, reducing energy consumption and extending equipment lifespan, making them an indispensable component for ensuring the normal operation of various equipment.

[0004] Currently, in the production process of graphite gaskets, metal rings are typically installed on the inner and outer sides of the gasket using a high-temperature resistant adhesive to increase overall strength. However, the material differences between graphite and metal can limit the bonding strength at the adhesive joint. Under conditions of high-frequency vibration, high pressure, or drastic temperature changes, the adhesive may struggle to maintain a tight bond between the metal ring and the graphite gasket. The metal ring can easily loosen or even detach, preventing the graphite gasket from achieving the expected reinforcement effect and consequently affecting its sealing performance and service life in the equipment.

[0005] Currently, no effective solution has been proposed to address the problem of unstable adhesive bonding in related technologies, which affects sealing performance. Utility Model Content

[0191] (III) Assembly Operation (using a two-graphite composite gasket structure as an example)

[0193] During the process, the alignment element 14 of another graphite composite gasket structure is docked with the alignment groove formed by the first outer reinforcing element 21 and the first inner reinforcing element 41 of another graphite composite gasket structure, and the alignment groove formed by the second outer reinforcing element 31 and the second inner reinforcing element 51.

[0194] The advantages of this utility model are:

[0195] 1. The main unit, first outer reinforcement unit, second outer reinforcement unit, first inner reinforcement unit, and second inner reinforcement unit are connected to the main unit via a snap-fit ​​mechanism. Compared to adhesive bonding, this snap-fit ​​structure is more stable. Under complex operating conditions such as equipment vibration and temperature changes, the snap-fit ​​joints are less prone to loosening, ensuring a tight connection between the reinforcement units and the main unit. Each reinforcement unit provides comprehensive reinforcement to the main unit from both the inside and outside. This structural design effectively distributes the pressure applied to the main unit during equipment operation, preventing damage to the gaskets due to excessive localized stress and improving the overall strength of the main unit.

[0196] 2. By utilizing the alignment element and the formed alignment groove, multiple graphite composite gaskets can be assembled together according to actual needs. The installation process is simple and quick. The installer only needs to align the mating element with the mating groove and insert it to complete the gasket splicing.

[0197] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
