AI Technical Summary
Traditional single-layer sealing gaskets cannot simultaneously meet the requirements of elastic compensation and mechanical strength under high pressure, high temperature or corrosive media conditions, which can easily lead to leakage when the flange surface is slightly deformed or vibrated.
A multi-layer sealing gasket structure is designed, including a gasket body, a surface layer, a buffer support component, a flame-retardant layer, a waterproof layer, and an anti-corrosion layer. Through the combination of a carbon fiber skeleton, graphite sheets, a silicone layer, and rubber pillars, it provides mechanical strength, waterproofing, anti-corrosion, flame retardancy, and energy-absorbing buffering effects.
It achieves waterproof, corrosion-resistant, flame-retardant, and stable support under high pressure, high temperature, or corrosive media conditions, solving the leakage problem of single-layer sealing gaskets in this environment.

Abstract
Claims
1. A new type of multi-layer sealing gasket comprising a gasket body (1) arranged in a circular ring shape, characterized in that: The outer surface of the gasket body (1) is composed of a surface layer (2) and a connecting layer (3). The surface layer (2) is provided with a buffer support component inside. The buffer support component is wrapped with a flame retardant layer (4) around its outer periphery. A waterproof layer (5) and an anti-corrosion layer (6) are provided between the flame retardant layer (4) and the surface layer (2).
2. A new multi-layer sealing gasket as claimed in claim 1, wherein: The buffer support assembly includes a carbon fiber skeleton (7) located between the surface layers (2). The carbon fiber skeleton (7) is symmetrically distributed and arranged in a transverse U-shape. Graphite sheets (8) are provided between the inner walls of the carbon fiber skeleton (7), and a silicone layer (9) is provided below the graphite sheets (8).
3. A novel multi-layer sealing gasket as claimed in claim 2, wherein: An arc-shaped plate (10) is fixedly connected between the graphite sheet (8) and the silicone layer (9). The arc-shaped plate (10) is evenly distributed and has a C-shaped cross-section. The arc-shaped plate (10) is made of an elastic material.
4. A new multi-layer sealing gasket according to claim 2 or 3, characterized in that: A reinforcing column (11) is fixedly connected between the graphite sheet (8) and the silicone layer (9), and they are arranged linearly. The reinforcing column (11) is located between the arc-shaped plates (10).
5. A new multi-layer sealing gasket as claimed in claim 2, wherein: A rubber column (12) is fixedly connected between the graphite sheet (8) and the silicone layer (9), and the rubber column (12) is arranged in a horizontal direction with a dumbbell-shaped cross section.
6. A novel multi-layer sealing gasket as claimed in claim 4, wherein: A rubber ring (13) is provided between the reinforcing column (11) and the arc plate (10).
