Problems solved by technology

However, under some severe working conditions of high temperature, high pressure and frequent alternation of temperature and pressure, the "V"-shaped skeleton or "W"-shaped skeleton of the wound gasket metal strip is easily affected by pressure, temperature changes and mechanical vibrations. Stress relaxation occurs, the resilience weakens and the seal fails

Abstract

The invention provides a winding gasket. The winding gasket comprises an elastic metal ring of an inner ring, an arc tooth skeleton ring of an outer ring and a sealing body arranged between the elastic metal ring and the arc tooth skeleton ring. Through the technical scheme, the elastic metal ring of the inner ring, the arc tooth skeleton ring of the outer ring and the sealing body arranged between the elastic metal ring and the arc tooth skeleton ring forms multiple seals, the risk of seal failure is greatly reduced. A multi-sealing type combination of the winding gasket has both a line sealand surface seal mode of the elastic metal ring of the inner ring and the arc tooth skeleton multi-channel line seal mode of the outer ring, and a variety of sealing modes cooperate with each other, the impact pressure of a media on a sealing surface is reduced layer by layer to form a comprehensive seal combination type with higher safety grade, the risk of seal failure is greatly reduced, and the seal performance is improved.

Description

technical field [0001] The invention relates to the technical field of sealing gaskets, in particular to a wound gasket. Background technique [0002] Spiral wound gaskets are generally composed of a metal inner ring, a sealing body, and a metal outer ring, wherein the sealing body is formed by spirally winding a metal strip and a non-metal strip. The deformed "V" or "W" skeleton of the metal belt provides continuous resilience, making the non-metallic belt contact with the flange surface, filling the microscopic unevenness and forming an effective seal, while the metal inner ring and the metal outer ring only play a role. Positioning and supporting roles. However, under some severe working conditions of high temperature, high pressure and frequent alternation of temperature and pressure, the "V"-shaped skeleton or "W"-shaped skeleton of the wound gasket metal strip is easily affected by pressure, temperature changes and mechanical vibrations. Stress relaxation occurs, and...
