Description

DEUTSCHESGERMAN

Die Erfindung betrifft eine leicht lösbare, nachgiebige und damit abwinkelbare Rohrverbindung, z. B. für Preßluftleitungen im Untertagebetrieb.The invention relates to an easily detachable, flexible and thus angled pipe connection, z. B. for compressed air lines in underground operations.

Es sind Rah rverbi η düngen bekannt, bei denen zum Rohrende hin kegelförmig aufgeweitete Rohrenden unter Zwischenschaltung elastischer, einteiliger Dichtungsringe durch eine zweiteilige, die Rohrenden umgreifende Küpplungsschelle zusammengehalten sind. Der Dichtungsring trägt auf der Außenfläche eine umlaufende Mittelrippe. An der Mittelrippe können nach außen ragende, umlaufende Wülste sitzen, die zwischen den Rohrenden und der Kupplungsschelle festgeklemmt sind. Der Dichtungsring ist weiterhin mit Dichtungsflügeln versehen, die nach der Rohrinnenseite hin winkelig auseinandergespreizt sind. Diese Dichtungsflügel müssen voll an der kegeligen Aufweitung anliegen, um zu vermeiden, daß das geförderte Medium nach außen tritt und Fremdkörper oder Ablagerungen zwischen die Dichtungsflügel und die Rohrenden gelangen.There are Rah rverbi η fertilize known, where for Pipe ends conically widened pipe ends with the interposition of elastic, one-piece sealing rings are held together by a two-part Küpplungsschelle encompassing the pipe ends. The sealing ring has a circumferential central rib on the outer surface. On the midrib, after outside protruding, circumferential beads sit, which are clamped between the pipe ends and the coupling clamp are. The sealing ring is also provided with sealing wings that face the inside of the pipe are spread apart at an angle. These sealing wings must fully adhere to the conical expansion in order to avoid that the conveyed medium escapes to the outside and foreign bodies or Deposits get between the sealing wings and the pipe ends.

Die Erfindung löst die Aufgabe, die Dichtungsflügel derart auseinanderzuspreizen, daß sie in jedem Falle fest an den kegeligen Aufweitungen anliegen. Erfindungsgemäß tragen die Innenflächen der Kupplungsschelle einen umlaufenden Spreizring. Dieser preßt sich in der Mittelebene in den Dichtungsring ein und spreizt dessen Dichtungsflügel auseinander. Diese Wirkung wird noch erhöht, wenn nach einem weiteren Erfindungsgedanken zwischen den Dichtungsflügeln eine zum Rohrinnern hin offene, vorzugsweise im Querschnitt annähernd kreisförmige Spreiznut ausgespart ist. Das geförderte Medium tritt unter dem Innendruck in die Spreiznut und drückt die Dichtungsfiügel auseinander.The invention solves the problem of spreading the sealing wings apart in such a way that they are in any case fit tightly to the conical widenings. According to the invention, the inner surfaces of the coupling clamp carry a circumferential expanding ring. This presses into the sealing ring in the middle plane and spreads its sealing wings apart. This effect is increased if, according to a further inventive concept between the sealing wings an open towards the inside of the pipe, preferably in cross section approximately circular expansion groove is recessed. The conveyed medium occurs under the internal pressure into the expansion groove and presses the sealing wings apart.
