CYLINDRICAL GASKET, METHOD FOR MANUFACTURING THE SAME, AND INSERTION-TYPE EXHAUST PIPE JOINT USING THE CYLINDRICAL GASKET |
摘要 |
A cylindrical gasket 27 includes a reinforcing member 70 made from a compressed belt-shaped metal wire net 5, a heat-resistant material 71 filled in meshes of the belt-shaped metal wire net 5 of the reinforcing member 70, and pores which are dispersedly distributed in the reinforcing member 70 and the heat-resistant material 71. An inner peripheral surface 23, an outer peripheral surface 24, and annular end faces 25 and 26 of the cylindrical gasket 27 are each formed by a smooth surface in which the heat-resistant material 71 and the reinforcing member 70 are present in mixed form. In the cylindrical gasket 27, the volume contents of the reinforcing member 70, the heat-resistant material 71, and the pores are 32 to 60%, 5 to 58%, and 10 to 35%, respectively. |

1. A cylindrical gasket for use in an insertion-type exhaust pipe joint, comprising: a reinforcing member made from a compressed metal wire net; a heat-resistant material filled in meshes of the metal wire net of said reinforcing member and containing graphite, acid-treated graphite, and an inorganic binder which are compressed; and pores which are dispersedly distributed in said reinforcing member and said heat-resistant material, wherein said reinforcing member and said heat-resistant material are intertwined with each other so as to be provided with structural integrity, said reinforcing member is contained densely in a radial direction from a cylindrical inner peripheral surface to a cylindrical outer peripheral surface, and with respect to a total volume of said cylindrical gasket, said reinforcing member occupies a volume of 32 to 60%, said heat-resistant material occupies a volume of 5 to 58%, and said pores occupy a volume of 10 to 35%. |
