Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the application is further described:

[0017] As shown in the attached figure, a flexible graphite gasket structure with a V-shaped protruding inner and outer ring is composed of an inner ring, an outer ring and flexible graphite. The inner ring and the outer ring are made of metal, and each has a concave Arc, with a V-shaped thorn, the height of the V-shaped thorn is about 2mm, and the thickness h of the inner and outer rings is 70% to 80% of the thickness H of the flexible graphite to control the appropriate amount of flexible graphite compression , between the inner ring and the outer ring is flexible graphite, and the flexible graphite, the inner ring and the outer ring are pressed to form an integral gasket.

[0018] The technical characteristics of realizing the present invention are: because the flexible graphite is pressed between the inner ring and the outer ring, and due to the relationship between the concave a...

Abstract

The invention belongs to the technical field of sealing, and particularly relates to a flexible graphite gasket with V-shaped with an inner ring and an outer ring with V-shaped protrusions. The flexible graphite gasket with V-shaped with the inner ring and the outer ring with the V-shaped protrusions comprises a flexible material, and the inner ring and the outer ring are arranged at the two endsof the flexile material correspondingly. The gasket sleeves the end of a pipeline to be sealed. The flexible graphite gasket has the remarkable effects that flexible graphite is located between the inner ring and the outer ring to be pressed into a whole, and therefore even though the gasket is mounted in an incompletely sealed space, the gasket cannot be scoured by a fluid medium to run off, andthe sealing performance can be kept for a long time.

Description

technical field [0001] The application belongs to the technical field of sealing, and in particular relates to a flexible graphite gasket with a V-shaped protruding inner and outer ring. Background technique [0002] Common flexible graphite gasket structures such as figure 1 As shown, it is made of pure flexible graphite and has good sealing performance. [0003] Disadvantages of this structure: the flexible graphite gasket needs to be installed in a closed space to obtain a good sealing effect. If it is not installed in a closed space, the flexible graphite will be lost under the scouring of the fluid medium and gradually lose its sealing performance. Contents of the invention [0004] The purpose of this application is to address the defects of the prior art and provide a flexible graphite gasket with a V-shaped thorn inner and outer ring. The gasket of this structure can be installed in an incompletely enclosed space without being eroded by the fluid medium. And the...
