Sealer production method and sealer produced by same

Abstract

The invention provides a sealer production method. The method includes 1) compositing a graphite plate with a core plate together to obtain a composite plate, 2) stamping the composite plate into a required size, 3) stamping a first protection plate and a second protection plate into required sizes respectively, 4) compositing the first protection plate and the second protection plate onto the top face and the bottom face of the composite plate respectively to obtain a sealing gasket. With the production method, the composite plate and the two protection plates are stamped and then composited so as to avoid thickness and appearance differences caused by stamping after the sealer is combined, so that consistency of edge thickness and central thickness of the produced sealer can be guaranteed, appearance performance is improved, and further sealing efficiency of the sealer in use is improved. The invention further provides the sealing gasket produced by the sealing gasket production method.

Description

technical field [0001] The present invention relates to the technical field of seal manufacturing, more specifically, to a method for manufacturing a gasket, and the invention also relates to a gasket produced by the manufacturing method. Background technique [0002] Gaskets are mainly used for flange sealing of pipelines of various media, pipe valves and various equipment. Limited by the length of the pipeline, the high-pressure gas pipe is generally composed of multiple pipes connected, and the two connected pipes are often sealed by a gasket to avoid the leakage of the medium in the exhaust pipe. [0003] The gasket is generally composed of a chip as a skeleton, and graphite plates are composited on both ends of the chip. In order to protect the graphite plate and prevent the graphite from falling off, stainless steel plates for protecting the graphite layer are respectively arranged on the two end surfaces of the graphite plate. [0004] At present, the production pro...

Problems solved by technology

However, the thickness of the gasket at the edge of the stamping is quite different from the middle of the gasket, and the appearance and performance are poor, which affects the sealing effect of the gasket during use.
