(FR) RACCORD DE TUYAUX
Abstract
(DE)
Die Erfindung betrifft einen Rohrverbinder mit einem Muffenelement, das ein konisch ausgebildetes Innengewinde besitzt, und mit einem Zapfenelement, das ein damit verschraubbares konisch ausgebildetes Außengewinde aufweist, wobei sich an die Gewindeabschnitte ein gewindefreier Abschnitt anschließen kann, der gegebenenfalls als metallischer Dichtsitz ausgebildet ist. Erfindungsgemäß weist ein Element (6, 21, 43) eine bekannte Gewindeflankenlinie konstanter Neigung (17, 24, 31, 39, 40) und das andere Element (1, 22, 44) im Hinblick auf die Kontur und/oder den Kegel davon abweichende Gewindeflankenlinie (16, 23, 30, 41, 42) auf.
(EN)
The invention concerns a pipe connector comprising a bush component with a conical internal thread and an internal component with a conical external thread such that these two components can be screwed together. The threaded sections can adjoin a smooth section which is optionally in the form of a metal sealing seat. One component (6, 21, 43) has a known thread flank line (17, 24, 31, 39, 40) of constant inclination and the other component (1, 22, 44) has a thread flank line (16, 23, 30, 41, 42) which deviates therefrom with respect to the contour and/or cone.
(FR)
L'invention concerne un raccord de tuyaux comportant un manchon à filet intérieur conique, ainsi qu'une pièce intérieure à filet extérieur conique permettant ainsi le vissage de ces deux éléments. Les parties filetées sont reliées à une partie non filetée conçue éventuellement sous forme de siège métallique étanche. Un élément (6, 21, 43) de ce raccord présente une ligne de flanc de filets (17, 24, 31, 39, 40) connue, d'inclinaison constante et l'autre élément (1, 22, 44) présente une ligne de flanc de filets (16, 23, 30, 41, 42) qui s'écarte au niveau du contour et/ou du cône.
