Abstract

The invention discloses a flange sealing device, comprising a connecting flange body; an epoxy primer coating is arranged on a connecting flange surface; the joints of a connecting flange are connected by glue injection; an external ring and an internal ring are arranged on the connecting flange body; an external ring sealing groove is formed on the external ring; an internal ring sealing groove is formed on the internal ring; sealing rings matching with each other are embedded in the external ring sealing groove and the internal ring sealing groove; and an adjusting handwheel is arranged at the edge of the connecting flange. Compared with the prior art, the flange surface is coated with an epoxy primer, so that the flange surface is improved; meanwhile, the glue injection is adopted and the sealing rings are arranged; the sealing rings are arranged in two sealing grooves; moreover, the air-tightness can be adjusted freely by rotating the handwheel manually, and the flange sealing device is flexible and accurate to use; the air leakage of the flange surface is improved greatly, so that the air-tightness of connecting pipelines by means of flanges is ensured and the influence caused by the leakage of materials is avoided.

Description

technical field [0001] The invention relates to a sealing structure, in particular to a flange sealing device. Background technique [0002] Flanges, also called flanges or flanges, are parts that connect pipes to each other and are connected to pipe ends. There are holes in the flange, and the bolts tightly connect the two flanges. The existing flanges are sealed with gaskets, most of which are sealed with ordinary rubber rings, which are easily corroded by materials in the petrochemical industry and never lose the sealing effect, resulting in pipeline leakage, resulting in material loss in the pipeline, polluting the plant, and causing Economic losses. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned technical problems, the present invention provides a flange sealing device, which can completely solve the above-mentioned problems. [0004] The technical scheme that solves the above-mentioned technical problem is as follo...
