Description

High-vacuum reusable sealing gasket

Technical Field

The utility model relates to a sealed technical field that fills up specifically is a high vacuum repeatedly usable fills up pad.

Background

Since the 21 st century, the contradiction between economic development and energy supply and environmental protection is increasingly prominent, and countries in the world take safety, high efficiency, environmental protection and economy as the subject of industrial development. This trend is mainly reflected in the petrochemical industry by the safe operation of high-temperature equipment and the compactness of the connection systems. The flange connection is widely applied to the connection part of a pressure pipeline and a pressure container in the petrochemical industry with the advantage of easy disassembly and assembly. When the flange is in a high vacuum working condition for a long time, the flange joint is easy to leak and lose efficacy. The flange end face of the common convex flange is a convex platform, bending moment can be generated on a flange plate under working conditions, the gasket is stressed unevenly, the flange plate deflects, and leakage is easy to occur. To this end, we propose a high vacuum reusable seal.
