Abstract
Description
Die Erfindung betrifft einen Abzweigsattel aus Kunststoff, mit einem Sattelstück und einem darin angeschweißten Abgangsrohr, sowie ein Verfahren zum Herstellen eines solchen Abzweigsattels.The The invention relates to a branch saddle made of plastic, with a saddle piece and one welded into it Outlet pipe, and a method for producing such a branch saddle.
Ein
derartiger Abzweigsattel ist beispielsweise aus der
Gerade bei Rohren mit großem Durchmesser ist die Schweißverbindung starken Belastungen ausgesetzt, so daß nicht mehr sichergestellt werden kann, daß sie über längere Zeiträume dicht und längskraftschlüssig bleibt.Just for pipes with large The diameter is the welded joint exposed to heavy loads, so that no longer ensured can become tight for long periods of time and remains restrained.
Es ist daher eine Aufgabe der Erfindung, einen Abzweigsattel aus Kunststoff so zu gestalten, daß auch bei großen Rohrdurchmessern eine über lange Zeiträume zuverlässige Schweißverbindung zwischen Sattelstück und Abgangsrohr besteht. Es ist auch die Aufgabe der vorliegenden Erfindung, ein Verfahren zum Herstellen eines solchen Abzweigsattels anzugeben.It is therefore an object of the invention, a branch saddle made of plastic to be designed in such a way that for large Pipe diameters one over long periods reliable Welded connection between saddle piece and outlet pipe. It is also the task of the present one Invention, a method for producing such a branch saddle specify.
Diese Aufgabe wird durch einen Abzweigsattel nach Anspruch 1 gelöst, vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche. Verfahren zum Herstellen eines Abzweigsattels sind in den Ansprüchen 7, 8 und 9 angegeben.This Object is achieved by a branch saddle according to claim 1, advantageous Refinements are the subject of the dependent claims. Manufacturing process a branch saddle are specified in claims 7, 8 and 9.
Erfindungsgemäß ist vorgesehen, daß bei einem Abzweigsattel aus Kunststoff das Sattelstück eine konisch ausgeschnittene Öffnung aufweist, in die ein Endabschnitt des Abgangsrohres eingesetzt ist, und daß im Grenzbereich zwischen Sattelstück und Abgangsrohr eine entsprechend der Innenfläche der Öffnung des Sattelstückes eine bevorzugt mäanderförmig verlaufende Heizwendel angeordnet ist, mittels derer eine fluiddichte Schweißverbindung zwischen Sattelstück und Abgangsrohr eingerichtet ist. Der Abzweigsattel wird üblicherweise auf ein Kunststoffrohr aufgesetzt, so daß es zweckmäßig ist, die Öffnung im Sattelstück so zu gestalten, daß der Konus an der vom Kunststoffrohr weg weisenden Seite enger ist als an der Auflagefläche zum Kunststoffrohr. Dann nämlich tritt eine Selbsthemmung der Bewegung des Abgangsrohres sowohl zum Kunststoffrohr hin als auch vom Kunststoffrohr weg ein. Grundsätzlich ist die Erfindung hierauf aber nicht beschränkt, und es kann denkbar sein, für nur auf Druck belastete Abgangsrohre den Konus der Öffnung im Sattelstück so zu gestalten, daß er an der Auflagefläche zum Kunststoffrohr hin enger ist als auf der vom Kunststoffrohr weg weisenden Seite. Durch die konisch ausgeschnitte Öffnung wird auch erreicht, daß eine größere Fläche zur Verfügung steht, auf der die Heizwendel, die in mehreren Wicklungen gelegt ist, wirken kann.According to the invention, that at a branch saddle made of plastic, the saddle piece has a conically cut opening, in which an end portion of the outlet pipe is inserted, and that in the border area between saddle and Outlet pipe one corresponding to the inner surface of the opening of the saddle piece preferably meandering Heating coil is arranged, by means of which a fluid-tight welded connection between saddle and outlet pipe is set up. The branch saddle is usually placed on a plastic tube, so that it is useful to open the opening in saddle piece to be designed so that the Cone on the side facing away from the plastic tube is narrower than on the contact surface to the plastic pipe. Then namely occurs a self-locking of the movement of the outlet pipe both Plastic tube towards and away from the plastic tube. Basically is the invention is not limited to this, however, and it may be conceivable for only outlet pipes loaded under pressure close the cone of the opening in the saddle shape that he on the contact surface towards the plastic pipe is narrower than that from the plastic pipe side pointing away. Through the conically cut opening also achieved that a larger area for disposal stands on which the heating coil is placed in several windings is, can work.
Bevorzugt ist die untere Fläche des Abgangsrohres zusätzlich mit einer Sattelwicklung für die Anbindung an das Kunftstoffrohr überdeckt.Prefers is the bottom surface of the outlet pipe additionally with a saddle winding for the Connection to the plastic pipe covered.
Nach einer vorteilhaften Ausgestaltung ist die Heizwendel mit der Innenfläche der Öffnung fluchtend in das Sattelstück eingebracht. Der Vorteil dieser Anordnung liegt in der ortsfesten Lage der Heizwendel beim Schweißvorgang, und Drahtverschiebungen, Schmelzenaustritte bzw. Kurzschlüsse durch die Verlagerung von Drähten werden ausgeschlossen. Dadurch wird die Schweißqualität wesentlich verbessert.To In an advantageous embodiment, the heating coil is aligned with the inner surface of the opening in the saddle brought in. The advantage of this arrangement is that it is stationary Position of the heating coil during the welding process, and wire displacements, melt leaks or short circuits the displacement of wires are excluded. This significantly improves the welding quality.
Es kann auch vorgesehen sein, die Heizwendel mit der Außenfläche des konischen Endabschnittes fluchtend in das Abgangsrohr einzubringen, was aber die obengenannten Vorteile nicht mit sich bringt.It can also be provided, the heating coil with the outer surface of the to bring the conical end section into alignment in the outlet pipe, but which does not have the advantages mentioned above.
Die Heizwendel kann auch in einen Schweißring aus Kunststoff eingebracht sein, der in einem Fügespalt zwischen Sattelstück und Abgangsrohr angeordnet ist. Nach dem Schweißvorgang hat sich der dünne Schweißring stoffschlüssig mit dem umgebenden thermoplastischen Material verbunden, sein Kunststoff, beispielsweise Polyethylen, wird zur Überbrückung des Schweißspaltes benutzt.The The heating coil can also be inserted into a plastic welding ring be the one in a joint gap between saddle and outlet pipe is arranged. After the welding process, the thin welding ring is cohesive the surrounding thermoplastic material, its plastic, for example polyethylene, is used to bridge the welding gap used.
