Description

Rohrverbindung Die Erfindung bezieht sich auf eine Rohrverbindung, bei der die Rohrenden zu Teilhohlkugeln verformt sind, die kugelgelenkartig ineinanderrasten und #x10bei die innere Hohlkugel in eine Dichtungslipnp ausläuft, die an der Innenfläche der äußeren Hohlkugel anliegt.Pipe connection The invention relates to a pipe connection, in which the pipe ends are deformed to partially hollow spheres that snap into one another like a ball joint and # x10 with the inner hollow sphere terminating in a sealing lip attached to the inner surface the outer hollow ball rests.

Bei Stahlrohren ist eine bleiverstemmte starre Kugelmuffenverbindung mit kugeliger Muffe und kugeligem Einsteckende bekanntgeworden, bei der an dem Einsteckende ein nach außen springender, der Kugelwand der Muffe angepaßter Bund (Dichtungslippe) als inneres Widerlager der Bleiverstemmung vorgesehen ist, der derart gestaltet und bemessen ist, daß er sich gegen die Innenwand der Kugelmuffe anlegt.Steel pipes have a lead-caulked rigid ball socket connection with spherical socket and spherical spigot end become known, in the case of the spigot end an outwardly jumping collar (sealing lip) adapted to the spherical wall of the socket is provided as an inner abutment of the lead caulking, which is designed in this way and is dimensioned so that it rests against the inner wall of the ball socket.

Es hat sich gezeigt, daß bei ähnlich gestalteten Rohrverbindungen, insbesondere dann, wenn diese als Kunststoffrohre ausgebildet sind, nicht immer eine gute Abdichtung bei dem Hindurchleiten von Fluden erreicht wird, vorzugsweise dann nicht, wenn man auf die umständliche Abdichtung der Bleiverstemmung verzichten will.It has been shown that with similarly designed pipe connections, not always, especially if these are designed as plastic pipes a good seal is achieved in the passage of fluids, preferably then not if you do without the cumbersome sealing of the lead caulking want.

Der Erfindung liegt die Aufgabe zugrunde, eine gute Abdichtung bei Kunststoffrohren auch dann zu erreichen, wenn keine Bleiverstemmung vorgenommen ist. Die Lösung dieser Aufgabe besteht darin, daß bei Anwendung auf Kunststoffrohre deren Außenkante zu einer Ringschneide zugeschärft ist, die unter einem Winkel an der Innenfläche der Außenkugel derart anliegt, daß sie sich beim Schließen der Verbindung in deren Material eingräbt. Hierbei.muß berücksichtigt werden, daß es sich bei der Erfindung nur um solche Rohrverbindungen handeln kann, bei denen die Rohre nach dem Schließen der Verbindung nicht mehr bewegt werden.The invention is based on the object of providing a good seal Plastic pipes can be reached even if no lead caulking has been carried out is. The solution to this problem is that when applied to plastic pipes the outer edge of which is sharpened to form a cutting edge that is at an angle the inner surface of the outer ball rests in such a way that it moves when the connection is closed digs into their material. It must be taken into account that the Invention can only be such pipe connections in which the pipes after cannot be moved after closing the connection.

Die Erfindung ist an Hand der Zeichnung durch ein Ausführungsbeispiel näher erläutert. An der inneren Teilhohlkugel 1 ist in der Nähe der vorderen Kante 2 eine zugeschärfte Ringlippe 3 vorgesehen, die beim Zusammenbau der beiden Rohrteile 4, 5 von innen her etwas in die Innenwandung der äußeren Teilhohlkugel eindringt, so daß eine gute Abdichtung gegenüber Fluden, wie Flüssigkeiten, Gasen u. dgl., erreicht wird, die die Rohrteile durchströmen. Die Krümmung der Ringlippe 3 unterstützt noch dieses Hineindringen der scharfen Schneide, weil der Winkel 6 zwischen der Schneidenkante 2 und der Innenfläche der Teilhohlkugel 7 verhältnismäßig groß ist, so daß die Eindringwirkung eine größere ist, als wenn dieser Winkel flacher ausgestaltet wäre. Die gute Abdichtung wird nicht allein durch die elastischen Eigenschaften des Innenrohres gewährleistet, durch die die Kante der Lippe von innen her gegen den Außenrohrteil gepreßt wird, sondern außerdem wirkt noch fördernd in Richtung auf gute Abdichtung die Tatsache, daß die Lippe infolge der Auswölbung nach innen einen freien Ringraum 8 gegenüber dem jeweiligen Außenrohrteil frei läßt. Durch den von innen auftretenden Druck in Richtung des Pfeiles 9, der durch das durchströmende Mittel auf die Lippe ausgeübt wird, wird sich diese verflachen, wie dies gestrichelt dargestellt ist. Dadurch streckt sich die Lippe etwas, und die vordere scharfe Kante 10 der Lippe wird sich wie ein Stechbeitel oder ein Meißel schiebend etwas in das Material an der Innenfläche des Außenrohres einarbeiten und dadurch die Abdichtung noch steigem.The invention is explained in more detail with reference to the drawing by means of an exemplary embodiment. On the inner partial hollow sphere 1 , near the front edge 2, a sharpened annular lip 3 is provided which, when the two pipe parts 4, 5 are assembled, penetrates somewhat from the inside into the inner wall of the outer partial hollow sphere, so that a good seal against fluids such as liquids , Gases and the like, is achieved, which flow through the pipe parts. The curvature of the annular lip 3 still supports this penetration of the sharp cutting edge, because the angle 6 between the cutting edge 2 and the inner surface of the partial hollow sphere 7 is relatively large, so that the penetration effect is greater than if this angle were made flatter. The good seal is not only ensured by the elastic properties of the inner tube, by means of which the edge of the lip is pressed from the inside against the outer tube part, but also the fact that the lip as a result of the bulge inwards has a positive effect on good sealing leaves a free annular space 8 opposite the respective outer pipe part. As a result of the pressure occurring from the inside in the direction of arrow 9, which is exerted on the lip by the medium flowing through, this will flatten out, as shown in dashed lines. As a result, the lip stretches somewhat, and the front, sharp edge 10 of the lip will work its way into the material on the inner surface of the outer tube by pushing a chisel or chisel, thereby increasing the seal even further.
