Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples:

as shown in fig. 1-3, the embodiment of the utility model provides a high-pressure pipeline circular ring sealing gasket, which comprises a metal gasket 1, wherein a plurality of through holes 2 matched with flange mounting holes are formed in the surface of the metal gasket 1, one or more annular grooves 3 are formed in both sides of the metal gasket 1, one or more annular grooves 3 are positioned between the plurality of through holes 2 and the metal gasket 1, O-shaped rings 5 are arranged in the one or more annular grooves 3, convex rings 4 are arranged on the upper surface and the lower surface of the plurality of through holes 2, when two flange plates are in butt joint, the convex rings 4 at the two ends of the through holes 2 are respectively inserted into the mounting holes of the two flange plates, the metal gasket 1 and the convex rings 4 are made of carbon steel materials, and rust-proof paint is coated on the surfaces of the metal gasket 1, the annular grooves 3 and the convex rings 4, so that the carbon steel strength is high, the service life is long, the rust-proof paint can be prevented from being rusted by the carbon steel, and the service life is further prolonged.
