"Rohrverbindung für doppelwand!ge Rohre""Pipe connection for double-walled pipes"

Vorliegende Erfindung hat zum Gegenstand eine Rohrverbindung für doppelv/andige Rohre, v/obei das innere Rohr aus gegen aggressive Flüssigkeiten und Gase v/iderstandsfähigem . Material besteht. Das wesentliche Merkmal dieser Erfindung besteht darin, dass das Ende des äusseren Rohres gegenüber dem inneren Rohr zurückgesetzt ist, wobei das vorstehende Ende des inneren Rohres mit einem Aussenkonus gegen einen Innenkonus gepresst und abgedichtet, während das äussere Rohr mit einem Klemmring, welcher einen Aussenkonus aufweist, festgehalten ist.The subject of the present invention is a pipe connection For double-sided pipes, the inner pipe is made of resistant to aggressive liquids and gases. Material consists. The main feature of this invention is that the end of the outer tube is opposite the inner tube is set back, the protruding end of the inner tube with an outer cone against a Inner cone pressed and sealed, while the outer tube is held in place with a clamping ring, which has an outer cone is.

Auf der beiliegenden Zeichnung ist ein Ausführungsbeispiel zur Durchführung der erfindungsgemässen Rohrverbindung in einer Ansicht, mit teilweisem Axialschnitt, dargestellt.The accompanying drawing shows an exemplary embodiment for carrying out the pipe connection according to the invention shown in a view with partial axial section.

Gemäss der dargestellten Ausführung wird mit 1 ein inneres Rohr, beispielsweise aus Kunststoff und mit 2 ein um dasselbe herum angeordnetes, äusseres, zweckmässigerweise aus Metall bestehendes Rohr bezeichnet. Um das eine RohrendeAccording to the embodiment shown, 1 is an inner tube, for example made of plastic, and 2 is a denotes the same, arranged around, outer tube, suitably made of metal. Around one end of the pipe

1, 2 ist ein Nippel 3 vorgesehen, dessen Aussengewinde h mit einem Innengewinde 5 einer auf dem anderen Rohrende 1, 2 sitzenden Muffe 6 verschraubt werden kann. Nippel 3, sowie Muffe 6 bestehen beispielsweise aus Temperguss. Um sowohl den Nippel 3, als auch die Muffe 6 auf den zugehörigen Rohrenden 1, 2 festzuhalten, sind in den Hohlräumen des Nippels 3 und der Muffe 6 je ein Klemmring 7 und ein Keilring 8 vorgesehen. Keilring 8 weist einen Anschlag auf, gegen v/elchen die Stirnseite des äusseren Rohres 2 ansteht. Beim Aufsetzen des Nippels 3, bzw. der Muffe 6, auf die Rohrenden 1, 2 erfolgt durch den Klemmring 7 eine Verklemmung, wodurch ein fester Pressitz entsteht. Der Keilring 8 besitzt in Richtung der Trennzone der Rohrenden 1, 2 eine sich in Richtung nach aussen ansteigende, kegelförmige Seitenfläche, die zur Begrenzung der Rohrbördelung dient. In dem zwischen den Rohrenden 1, 2 befindlichen Raum ist ein aus Metall bestehender Zwischenring 9 vorgesehen, dessen Querschnitt dreieckig, mit den spitzen Winkeln in Richtung gegen die Rohrenden 1, 2 hin, ausgebildet ist. Die Seitenflächen des Zwischenringes 9 sind kegelförmig. Um ein Austreten der in den Rohren 1, 2 befindlichen Flüssigkeit oder Gase durch die Gewinde *f, 5 in die Hohlräume des Nippels 3 und der Muffe 6, sowie in's Freie, zu verhindern, sind auf den Seitenflächen des Zwischenringes 9 koaxiale, umlaufende Rippen 11 angeordnet, die eine völlige Abdichtung gewährleisten. Der Zwischenring besteht aus rostfreiem Stahl. Bei Verwendung eines anderen Metalls kann die gesamte Oberfläche des Zwischenringes 9 mit einem Korrosions-1, 2 a nipple 3 is provided, the external thread h of which can be screwed to an internal thread 5 of a socket 6 seated on the other pipe end 1, 2. Nipple 3 and socket 6 are made of malleable cast iron, for example. In order to hold both the nipple 3 and the socket 6 on the associated pipe ends 1, 2, a clamping ring 7 and a wedge ring 8 are provided in each of the cavities of the nipple 3 and the socket 6. Wedge ring 8 has a stop against which the end face of the outer tube 2 rests. When the nipple 3, or the sleeve 6, is placed on the pipe ends 1, 2, the clamping ring 7 jams, which creates a tight interference fit. The wedge ring 8 has, in the direction of the separation zone of the pipe ends 1, 2, a conical side surface which rises towards the outside and serves to limit the pipe flanging. In the space located between the pipe ends 1, 2, an intermediate ring 9 made of metal is provided, the cross section of which is triangular, with the acute angles in the direction towards the pipe ends 1, 2. The side surfaces of the intermediate ring 9 are conical. In order to prevent the liquid or gases in the pipes 1, 2 from escaping through the threads * f, 5 into the cavities of the nipple 3 and the sleeve 6, as well as into the open, there are coaxial, circumferential ribs on the side surfaces of the intermediate ring 9 11 arranged, which ensure a complete seal. The intermediate ring is made of stainless steel. When using a different metal, the entire surface of the intermediate ring 9 can be treated with a corrosion

Falls der Nippel 3 mit der Muffe 6 verschraubt wird, zu welchem Zwecke dieselben mit ebenen Aussenflachen 10 zum Ansetzen von Schraubenschlüsseln versehen sind, werden die doppelwandlgen Rohre 1, 2 einander genähert, wobei die Rohrenden 1 auf den Zwischenring 9 stossen, dessen in das Rohr- -innere hineinragende Kanten bewirken, dass die Rohrenden auf die ihnen zugewandten Seiten des Zwischenringes 9 gestülpt werden. Somit erfolgt eine Aufbördelung beider Rohrenden 1 in Richtung nach aussen, wobei die Seitenflächen des Zwischenringes 9 auf den betreffenden Innenwandungen der Kunststoffrohre 1, dank der Rippen 11, dicht anliegen.If the nipple 3 is screwed to the socket 6, for which purpose the same are provided with flat outer surfaces 10 for the attachment of wrenches, the double-walled pipes 1, 2 are brought closer to one another, the pipe ends 1 meeting the intermediate ring 9, which is in the pipe - - Inner protruding edges have the effect that the pipe ends are placed on the sides of the intermediate ring 9 facing them. Both pipe ends 1 are thus flared outwards, with the side surfaces of the intermediate ring 9 resting tightly on the relevant inner walls of the plastic pipes 1 thanks to the ribs 11.

Die erfindungsgemässe Rohrverbindung ermöglicht eine einwandfreie, rasche und wirtschaftliche Verbindung für doppelwandige Rohre, beispielsweise gepanzerte Kunststoffrohre. The pipe connection according to the invention enables a perfect, quick and economical connection for double-walled pipes, for example armored plastic pipes.
