Abstract

The invention discloses a metal gasket. More than one layer of metal fiber filaments distributed uniformly in a net shape is arranged in a metal material of the metal gasket, and a hemispherical concave part is arranged on a sealing surface of the metal gasket. By adding the metal fiber filaments, the anti-flushing strength of the auxiliary metal gasket can be remarkably improved, the service life of the whole sealing gasket is prolonged, and leakage resistance of connection of sealing elements is effectively improved.

Description

technical field [0001] The invention relates to high-pressure leak-proof technology, in particular to a metal gasket for auxiliary connection and sealing of high-temperature and high-pressure connectors. Background technique [0002] The combined connection structure of flange-gasket-bolt is the most widely used pipeline connection method in machinery, petroleum, chemical and other industries. As the basic element of pipeline connection, it occupies a very important position in modern industry. It not only ensures the connection and sealing between pipelines, pipelines and equipment, but also facilitates the disassembly and assembly of pipelines during construction, installation and maintenance. The sealing of the gasket is the core of the flange connection. In order to enhance the sealing performance of the gasket, a flexible metal auxiliary gasket is usually added between the gasket and the connecting piece, such as the winding gasket and corrugated tooth gasket commonly u...
