Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the application is further described:

[0012] as attached figure 1 , 2 As shown, a wound gasket structure is formed by winding V-shaped steel strips, and non-metallic materials such as flexible graphite are filled between the steel strips. The direction of the V-shaped notch of the V-shaped steel strip faces away from the outer circle of the gasket. center line.

[0013] The technical features of the present invention are: a wound gasket structure, which is formed by winding V-shaped steel strips, and non-metallic materials such as flexible graphite are filled between the steel strips, and the direction of the V-shaped notch of the V-shaped steel strips faces away from to the center line of the outer circle of the gasket. Since the direction of the V-shaped notch of the V-shaped steel belt is facing away from the centerline of the outer circle of the gasket, when the gasket is subjected to external pressure of the medi...

Abstract

The invention belongs to the technical field of sealing, and particularly relates to a spiral wound gasket structure. The spiral wound gasket suitable for external pressure sealing comprises steel strips and flexible graphite, wherein the steel strips are V-shaped steel strips, the V-shaped steel strips are wound, and gaps between the steel strips are filled with the flexible graphite. The gaskethas the remarkable effects that the direction of V-shaped notches of the V-shaped steel strips is arranged back on to the center line of the outer circle of a gasket, so that when the gasket bears theexternal pressure of a medium, the external pressure medium acts on the V-shaped notches so as to increase the sealing load of the gasket, and the sealing performance under the condition of externalpressure of the medium is facilitated.

Description

technical field [0001] The application belongs to the technical field of sealing, and in particular relates to a wound gasket structure. Background technique [0002] Common wound gasket structures such as figure 1 As shown, it is made of V-shaped steel strips, and non-metallic materials such as flexible graphite are filled between the steel strips. The direction of the V-shaped notch of the V-shaped steel strip of this wound gasket is directly facing the center of the outer circle of the gasket. Line, so it has good sealing performance to withstand the internal pressure of the medium. [0003] The disadvantage of this wound gasket: it is not conducive to the sealing of the gasket under the external pressure of the medium. Contents of the invention [0004] The purpose of this application is to address the defects of the prior art and provide a wound gasket structure, so that the gasket has good sealing performance when subjected to external pressure of the medium.
