Title
(EN) TEMPORARY HOLDING STRUCTURE FOR GASKET
(FR) STRUCTURE DE MAINTIEN TEMPORAIRE POUR JOINT D'ÉTANCHÉITÉ
(JA) ガスケットの仮保持構造
Abstract
(EN)
A temporary holding structure for a gasket, which temporarily holds a gasket (4) relative to a first circulation pipe (2) when a first V-band flange (12) of the first circulation pipe (2) and a second V-band flange (22) of a second circulation pipe (3) are connected with a V-band (5). The first circulation pipe (2) has a circulation pipe distal-end part (20) that protrudes farther to one side than the first V-band flange (12). The gasket (4) has a gasket main body part (31) and a protruding part (32) that protrudes radially inward from a partial region of the inner peripheral edge of the opening of the gasket main body part (31). The opening of the gasket main body part (31) is larger than the outer diameter of the circulation pipe distal-end part (20). The protruding part (32) of the gasket (4) is formed with a length such that when the circulation pipe distal-end part (20) is inserted into the opening of the gasket main body part (31), the protruding part contacts the outer peripheral surface (26) of the circulation pipe distal-end part (20) and undergoes elastic deformation.
(FR)
L'invention concerne une structure de maintien temporaire destinée à un joint d'étanchéité, qui maintient temporairement un joint d'étanchéité (4) par rapport à un premier tuyau de circulation (2) lorsqu'une première bride à bande en V (12) du premier tuyau de circulation (2) et une seconde bride à bande en V (22) d'un second tuyau de circulation (3) sont reliées par une bande en V (5). Le premier tuyau de circulation (2) a une partie d'extrémité distale de tuyau de circulation (20) qui fait saillie plus loin d'un côté que la première bride à bande en V (12). Le joint d'étanchéité (4) a une partie corps principal de joint d'étanchéité (31) et une partie saillante (32) qui fait saillie radialement vers l'intérieur à partir d'une région partielle du bord périphérique interne de l'ouverture de la partie corps principal de joint d'étanchéité (31). L'ouverture de la partie corps principal de joint d'étanchéité (31) est plus grande que le diamètre externe de la partie d'extrémité distale de tuyau de circulation (20). La partie saillante (32) du joint d'étanchéité (4) est formée d'une longueur telle que lorsque la partie d'extrémité distale de tuyau de circulation (20) est insérée dans l'ouverture de la partie corps principal de joint d'étanchéité (31), la partie saillante vient en contact avec la surface périphérique externe (26) de la partie d'extrémité distale de tuyau de circulation (20) et subit une déformation élastique.

第1の流通管(2)の第1のVバンドフランジ(12)と第2の流通管(3)の第2のVバンドフランジ(22)をVバンド(5)で連結する際に、ガスケット(4)を第1の流通管(2)に対して仮保持するガスケットの仮保持構造である。第1の流通管(2)は、第1のVバンドフランジ(12)よりも一側へ突出する流通管先端部(20)を有する。ガスケット(4)は、ガスケット本体部(31)と、ガスケット本体部(31)の開口の内周縁の一部の領域から径方向内側へ突出する突出部(32)とを有する。ガスケット 本体部(31)の開口は、流通管先端部(20)の外径よりも大きい。ガスケット(4)の突出部(32)は、流通管先端部(20)をガスケット本体部(31)の開口に挿通した状態で、流通管先端部(20)の外周面(26)に当接して弾性変形する長さに形成される。
