The exhaust pipe interface gasket includes a gasket body. The central position of the gasket body is provided with a gasket through hole that matches the size of the flange through hole.
The mica sheet on the upper and lower sides of the genus sheet is superimposed. A sealing gasket is embedded in the inner wall of the through hole of the metal sheet. The edge of the through hole of the gasket is provided with a metal edging. The sealing gasket is covered with the mica sheet by the metal edging. . The gasket uses the metal sheet as the middle layer to be laminated through three layers, which makes the structure strong, rigid and not easy to deform; the inner ring of the metal sheet is embedded with the sealing gasket, so that both sides of the gasket can be closely attached to the flange, which not only increases the seal The performance also increases the specific pressure between the gasket and the sealing surface, so that the same sealing effect can be achieved when the medium pressure of the pipeline increases; the metal edging can further increase the firmness of the gasket. The utility model has the characteristics of reasonable structure, good sealing performance and long service life, and can be used for sealing connection in various pipeline ventilation.
