Description
Durch solche Verformungen frißt sich nämlich die Überwurfmutter sehr
leicht auf der Dichtungshülse fest, so daß diese die Drehung der Überwurfmutter
mitmacht, was für eine sichere Abdichtung unbedingt vermieden werden muß. Aus diesem
Grunde werden daher immer noch unsymmetrisch ausgebildete Dichtungshülsen verwendete
die an einem Ende eine kegelförmige Fläche für die Überwurfmutter aufweisen, am
anderen Ende jedoch im wesentlichen zylindrisch ausgebildet sind. Der Nachteil dieser
Dichtungshülsen besteht
Die neue Rohrverschraubung hat den Vorteil, daß der Arbeiter bei der
Montage kein Augenmerk darauf zu richten hat, daß die Dichtungshülse in richtiger
Lage auf das Rohr aufgeschoben wird, denn die richtige Lage der Dichtungshülse ist
stets gewährleistet, gleichgültig, wie die Dichtungshülse auf das Rohr aufgeschoben
wird. Die Röhrgverschraubung ist
äußerst einfach herzustellen. Ihre
Anwendung erfordert keine besonders große Kraft und trotzdem
Auf die Enden der Röhre 6 sind Dichtungshülsen 7 Aufgeschoben. Jede Dichtungshülse 7 besitzt in ihrer Mitte einen Bund 8 mit trapezförmigem Querschnitt.Sealing sleeves 7 are pushed onto the ends of the tube 6. Every Sealing sleeve 7 has in its center a collar 8 with a trapezoidal cross-section.
Die Seitenflächen 8' des Bundes sind den Flächen 5 der Überwurfmutter 4 genau parallel. Die Bohrung der Überwurfmutter ist dabei so groß, daß sich die Überwurfmutter 4 mit der Dichtungshülse 7 nur mit den flächen 5 und 8' berühren.The side surfaces 8 'of the collar are the surfaces 5 of the union nut 4 exactly parallel. The bore of the union nut is so large that the Only touch the union nut 4 with the sealing sleeve 7 with the surfaces 5 and 8 '.
Auf jeder Seite des Bundes 8 ist die Oberfläche 9 der Hülse 7 kegelförmig ausgebildet, so daß sich die Hülse nach beiden Enden symmetrisch verjüngt.On each side of the collar 8, the surface 9 of the sleeve 7 is conical formed so that the sleeve tapers symmetrically towards both ends.
Die Stirnflächen 10 der Hülsen 7 sind kegelförmig so versenkt, daß sie in den Berührungspunkten im wesentlichen senkrecht zu den kegelförmigen Flachen des Sitzes 3 des Anschlußstückes 2 verlaufen. Vor dem Festziehen der Überwurfmutter 4 (s. oberer Teil der Zeichnung) liegt ihre Fläche 5 an der Fläche 8' des Bundes 8 der Diehtungshulse 9 an Der obere Rand der Stirnfläche 10 der in den Sitz 3 des Anschlußstückes 2 eingeführten Hülsennalfte berührt die kegelförmige Fläche dieses Sitzes, Beim Anziehen der Überwurfmutter 4 wird die Bnise 7 in den Sitz 3 hineingedrückt.The end faces 10 of the sleeves 7 are countersunk conically so that at the points of contact they are essentially perpendicular to the conical surfaces of the seat 3 of the connector 2 extend. Before tightening of the union nut 4 (see upper part of the drawing) is its surface 5 on the surface 8 'of the collar 8 of the Diehtungshulse 9 on the upper edge of the end face 10 of the in the seat 3 of the connecting piece 2 introduced sleeve half touches the conical Area of this seat, When tightening the union nut 4, the screw 7 is in the Seat 3 pushed in.
Dabei wird das innere Ende der Hülse durch die
