Embodiment Construction

[0015] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0016] Such as Figure 1~6 The shown gasket structure for the flange includes a gasket 2, a through hole is provided in the middle of the gasket 2, and a threaded connection hole 6 corresponding to the bolt hole 7 of the flange is provided on the circumference of the gasket 2. Raised rings 8 are provided on the upper and lower surfaces.

[0017] In the above solution, the upper and lower raised rings 8 correspond to each other. Since the two protruding rings 8 are corresponding, when the sealing gasket 2 is squeezed by the flange, the structure is stable and the force is uniform.

[0018] In the above solution, a cavity 5 is provided between the upper and lower raised rings 8 . The cavity 5 ensures proper deformation of the gasket 2 .

[0019] The working process of the present invention is as follows: the upper and lower surfaces of the gasket 2 are...

Abstract

The invention discloses a sealing gasket structure for flanges. The sealing gasket structure for the flanges comprises a sealing gasket, a through hole is formed in the middle of the sealing gasket, threaded connecting holes corresponding to flange connecting holes are formed in the circumferential direction of the sealing gasket, and raised rings are arranged on the upper surface and the lower surface of the sealing gasket. The sealing gasket structure for the flanges has the advantages that since the raised rings are arranged on the upper surface and the lower surface of the sealing gasket and the sealing gasket is arranged between the two flanges, the raised rings can be in close contact with the surfaces of the flanges under the squeezing effect of the flanges on the two sides to form a good seal and the sealing gasket can become tighter under the squeezing effect under the effect of high-temperature waste gas during working; the manufacturing technology is simple and the sealing performance is good.

Description

technical field [0001] The invention relates to the technical field of vehicles and engineering machinery parts, in particular to a gasket structure for a flange. technical background [0002] Flange connection is a common connection method for engine exhaust system. In order to ensure the tightness of the exhaust system and reduce exhaust leakage, a gasket must be installed at the flange connection. The traditional method usually uses a gasket, and under the extrusion of the flanges at both ends, the gasket is extruded and deformed to fit the two flange surfaces. However, since the gasket only has protrusions on one side, the gasket is not tightly attached to one of the flanges, and the sealing performance is poor. Contents of the invention [0003] The present invention aims at the above problems and provides a gasket structure for flanges, which can well solve the above problems and provide good sealing performance. [0004] In order to achieve this purpose, the flang...
