Description

Technical Field

[0001] The utility model relates to the technical field of sealing gaskets, in particular to a sealing gasket and a sealing structure using the sealing gasket. Background Art

[0002] Sealing gaskets are a kind of sealing spare parts used in machinery, equipment, pipelines as long as there is fluid. They are used inside and outside to act as a seal. Sealing gaskets are made of metal or non-metallic plate materials through cutting, stamping or tailoring. They are used for sealing connections between pipelines and between parts of machinery and equipment. They can be divided into metal sealing gaskets and non-metallic sealing gaskets according to the material. Metal gaskets include copper gaskets, stainless steel gaskets, iron gaskets, aluminum gaskets, etc. Non-metallic gaskets include asbestos gaskets, non-asbestos gaskets, paper gaskets, rubber gaskets, etc.

[0003] Flange connection is a detachable joint that fixes two pipes, pipe fittings or equipment on a flange plate respectively, then adds a flange gasket between the two flange plates, and finally tightens the two flange plates with bolts to make them tightly combined. Flange gaskets generally use rubber gaskets. The existing flange sealing gaskets have poor sealing effect, and the sealing gaskets are easy to slip off during installation, which is inconvenient to install. At the same time, the existing flange sealing structure has poor sealing effect, and is prone to leakage after long-term use. During disassembly and assembly, the stability effect is not good. For this reason, we propose a sealing gasket and a sealing structure using the sealing gasket. Utility Model Content
