Title
(DE) LÖSBARE ROHRVERBINDUNG FÜR KUNSTSTOFFROHRE
(EN) DETACHABLE PIPE JOINT FOR PLASTIC PIPES
(FR) RACCORD AMOVIBLE POUR TUYAUX EN PLASTIQUE
Abstract
(DE)
Um bei einer lösbaren Rohrverbindung für Kunststoffrohre, die eine Muffe (1) zur Aufnahme des Rohrendes (20) und eine Stützhülse (21) aufweist, eine zuverlässige Abdichtung unter allen zu erwartenden Betriebsbedingungen zu gewährleisten, die kostengünstig ausführbar sein soll und in der Handhabung der Rohrverbindung gegenüber der bekannten Rohrverbindung keine Nachteile mit sich bringt, schlägt die Erfindung folgende Merkmale vor: Die Stützhülse (21) enthält einen äußeren, gegenüber dem Rohrende (20) vorstehenden Hülsenabschnitt (23), am vorstehenden Hülsenabschnitt (23) ist mit Abstand vom freien Ende ein Außenflansch (24) als Einschubbegrenzung angeformt, der vorstehende Hülsenabschnitt (23) besitzt außen wenigstens eine umlaufende Nut (25) mit einem darin gehaltenen elastischen Dichtring (26), die Muffe (1) weist an ihrem freien Ende eine zur Rohrachse konzentrische Bohrung (27) mit glatter Wandung auf, deren Innendurchmesser dem Außendurchmesser des vorstehenden Hülsenabschnittes (23) entspricht, und in der Verbindungsstellung ist der vorstehende Hülsenabschnitt (23) in der Bohrung (27) der Muffe (1) formschlüssig geführt.
(EN)
A pipe joint having a bushing (1) to receive the pipe end (20) and a supporting sleeve (21) can be reliably sealed in all foreseeable operating conditions, economically produced and handled without any disadvantages compared with known pipe joints. For that purpose, the following features are disclosed: the supporting sleeve (21) has an outer sleeve section (23) that projects over the pipe end (20); an outer flange (24) is shaped at the projecting sleeve section (23) at a distance from the free end to stop the pipe from sliding further in; the projecting sleeve section (23) has at least one outer circumferential groove (25) with an elastic packing ring (26) held therein; the bushing (1) has at its free end a bore (27) concentrically arranged about the axis of the pipe and having a smooth wall whose inner diameter corresponds to the outer diameter of the projecting sleeve section (23); in the joined position, the projecting sleeve section (23) is form-fittingly guided in the bore (27) of the bushing (1).
(FR)
L'invention concerne un raccord amovible pour tuyaux en plastique, qui comprend un embout (1) destiné à recevoir l'extrémité (20) d'un tuyau et un manchon d'appui (21). Afin de parvenir à une étanchéité fiable dans toutes les conditions de fonctionnement possibles, qui soit économique à réaliser et à une manipulation du raccord pour tuyaux qui ne présente pas d'inconvénient comparativement aux autres raccords pour tuyaux connus, il est prévu que ce raccord présente les caractéristiques suivantes: le manchon d'appui (21) comprend une section (23) extérieure saillante par rapport à l'extrémité (20) du tuyau; un bord extérieur (24) formé au niveau de la section (23) saillante du manchon, à distance de l'extrémité libre, fait office de limiteur d'emboîtement; la section (23) saillante du manchon présente à l'extérieur au moins une rainure (25) périphérique muni à l'intérieur d'une bague d'étanchéité (26) élastique; à son extrémité libre, l'embout (1) présente un alésage (27) à paroi lisse, concentrique à l'axe du tuyau, et dont le diamètre intérieur correspond au diamètre extérieur de la section (23) saillante du manchon; et en position de jonction, la section (23) saillante du manchon est guidée par liaison de forme dans l'alésage (27) de l'embout (1).
