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)
This temporary holding structure for a gasket (4) is for, when a first V band flange (12) of a first circulation pipe (2) and a second V band flange (22) of a second circulation pipe (3) are fastened and coupled with a V band (5), temporarily holding the gasket (4) interposed between the first V band flange (12) of the first circulation pipe (2) and the second V band flange (22) of the second circulation pipe (3) with respect to the first V band flange (12) of the first circulation pipe (2). The outer peripheral surface (17) of the first V band flange (12) of the first circulation pipe (2) has a non-contact area (15) that, when being fastened with the V band (5), is spaced apart from the inner peripheral surface (46) of the V band (5) to the radially inner side. The first V band flange (12) of the first circulation pipe (2) has a pipe-side locking part (16) that is formed in the non-contact area (15). The gasket (4) has a gasket-side locking part (32) that is locked at the pipe-side locking part (16) of the first V band flange (12) of the first circulation pipe (2).
(FR)
L'invention concerne une structure de maintien temporaire pour un joint d'étanchéité (4), laquelle structure est destinée, quand une première bride de bande en V (12) d'un premier tuyau de circulation (2) et une seconde bride de bande en V (22) d'un second tuyau de circulation (3) sont fixées et couplées à une bande en V (5), à maintenir temporairement le joint d'étanchéité (4) interposé entre la première bride de bande en V (12) du premier tuyau de circulation (2) et la seconde bride de bande en V (22) du second tuyau de circulation (3) par rapport à la première bride de bande en V (12) du premier tuyau de circulation (2). La surface périphérique externe (17) de la première bride de bande en V (12) du premier tuyau de circulation (2) a une zone de non contact (15), qui, quand elle a été fixée à la bande en V (5), est espacée de la surface périphérique interne (46) de la bande en V (5) vers le côté radialement interne. La première bride de bande en V (12) du premier tuyau de circulation (2) a une partie de verrouillage de côté tuyau (16) qui est formée dans la zone de non contact (15). Le joint d'étanchéité (4) a une partie de verrouillage de côté joint d'étanchéité (32) qui est verrouillée à la partie de verrouillage de côté tuyau (16) de la première bride de bande en V (12) du premier tuyau de circulation (2).
