摘要:
A gasket for compressible placement between a first surface and a second surface is disclosed. In one embodiment, the gasket has a cellular metal skeleton embedded in a viscoelastic, pliable, deformable tacky polymer body. The skeleton has multiple strands, which connect to form multiple interconnected cells or pores. The skeleton, prior to being encapsulated in the tacky polymer body, is typically about 75% or more void space. The void space is substantially filled in the manufacture of the gasket, with the tacky uncured polymer. The uncured polymer will set up or cure, and then the gasket may be used.

A gasket in which a high sealing property can be ensured, and a method of producing such a gasket are provided. A gasket 1 is produced by spirally winding a beltlike composite body 13 having a metal mesh member 11 and expanded graphite 12 enveloped by the metal mesh member, and then compression molding the composite body into a tubular shape. The gasket includes a first sealing portion 21 placed in one axial end portion, and a second sealing portion 22 placed in the other axial end portion. The gasket has a sectional shape in which the composite body that is in a bent state overlaps in a radial direction. The composite body includes a bent portion which is radially bent in an acute angle shape.

The invention relates to a sealing assembly for flat flange connections which comprises an annular metal main body (1), which is composed of a metal sheet, and annular soft-material supports (2) on the two sides. Teeth or corrugations (3, 4, 5, 6) are annularly impressed into the metal main body (1). The sealing assembly has the following dimension combination in the original state thereof before the installation into the flange connection: the metal sheet thickness of the metal main body (1) is at least 0.5 mm, preferably at least 0.6 mm, more preferably at least 0.8 mm, and even more preferably at least 1.0 mm. The metal sheet thickness of the metal main body (1) is at most 1.5 mm and preferably at most 1.2 mm. The distance between the vertices (3a, 4a, 5a, 6a) of each pair of adjacent annular teeth (3, 4, 5, 6) pointing in the same direction is greater than 3 mm and preferably greater than 4 mm. The thickness of the metal main body (1) measured over the vertices (3a, 4a, 5a, 6a) of the annular teeth (3, 4, 5, 6) is at least 2 mm and preferably at least 3 mm. The thickness of the metal main body (1) measured over the vertices (3a, 4a, 5a, 6a) of the annular teeth (3, 4, 5, 6) is at most 6 mm, preferably at most 5 mm, and even more preferably at most 4 mm.
摘要:
In a spherical annular seal member 38, a spherical annular base member 36 is constructed so as to be provided with structural integrity as a heat-resistant material 6 and a reinforcing member 5 are compressed to each other and intertwined with each other. In an outer layer 37, the heat-resistant material 6, a sintered solid lubricant constituted by a lubricating composition, and the reinforcing member 5 made from a metal wire net are compressed such that the sintered solid lubricant and the heat-resistant material 6 are filled in meshes of the metal wire net of the reinforcing member 5, and the solid lubricant, the heat-resistant material 6, and the reinforcing member 5 are integrated in mixed form, an outer surface 39 of that outer layer 37 being thus formed into a smooth surface 42 in which a surface 40 constituted by the reinforcing member 5 and a surface 41 constituted by the sintered solid lubricant are present in mixed form.
