Rohrverbindung mit einer das Rohrende umgebenden MuffePipe connection with a sleeve surrounding the pipe end
Patentiert im Deutschen Reiche vom 25. September 1925 abPatented in the German Empire on September 25, 1925
Es ist bereits vorgeschlagen worden, Rohrverhindungen
mit Hilfe einer das Rohrende umgebenden Mutte herzustellen, die in der
nach außen erweiterten Bohrung ein plastisches Dichtungsmaterial und einen mittels
einer Überwurfmutter festzuziehenden Druck ring aulnimmt. Dabei bildeten die innere
Stirnfläche des Druckringes und der Boden des erweiterten Teiles der Muffenbohrung
zur Rohrachse senkrechte Ebenen oder nur wenig dagegen geneigte Kegelflächen. Infolgedessen
wurde das plastische Dichtungsmaterial einem fast rein axialen Druck ausgesetzt.
Gemäß der Erfindung sind im Gegensatz hierzu die genannten Druckflächen gegen eine
zur Rohrachse senkrechte Ebene mn einen Winkel von mindestens 45 ° geneigt. Dadurch
ergibt sich, beim Zusammenpressen des Dichtungsmaterials
zwischen den Druckflächen eine erheblich einwärts gerichtete Druekkomponente.
Durch diese wird das plastische Packungsmaterial nach der Rohrwand hin verschoben, auf die es einen so starken Druck
ausübt, daß es bei entsprechendem Material und entsprechender Wandstärke des Rohres
die Rohrwand nach innen einbeult. s Hierfür . ist nicht nur die erwähnte Form der Druckflächen,
sondern auch die Verwendung eines plastischen Packungsmau-rials Voraussetzung.It has already been proposed to produce pipe connections with the aid of a nut surrounding the pipe end, which assumes a plastic sealing material and a pressure ring to be tightened by means of a union nut in the outwardly widened bore. The inner end face of the pressure ring and the bottom of the enlarged part of the socket bore formed planes perpendicular to the pipe axis or only slightly inclined conical surfaces. As a result, the plastic sealing material was subjected to almost purely axial pressure.
According to the invention, in contrast to this, the mentioned pressure surfaces are inclined at an angle of at least 45 ° with respect to a plane mn perpendicular to the pipe axis. This results in a considerably inwardly directed pressure component when the sealing material is pressed together between the pressure surfaces. As a result of this, the plastic packing material is displaced towards the pipe wall, on which it exerts such a strong pressure that, given the appropriate material and wall thickness of the pipe, it buckles the pipe wall inward. s for this. is not only the mentioned shape of the pressure surfaces, but also the use of a plastic packing mural is a prerequisite.
Dichtungen, bei denen zwar die Stirnfläche des Druckringes und die Bodenfläche des Muitenzwischenraumes entsprechend geformt sind, aber kein plastisches Material Verwendung findet, können den verfolgten Zweck nicht erfüllen, weil die Packung nicht radial zusammendrückbar ist.Seals, in which, although the face of the pressure ring and the bottom surface of the Muitentenzaperspace are shaped accordingly, but no plastic material is used finds, cannot fulfill the intended purpose because the packing is not radial is compressible.
Mau hat zwar auch schon mit nichtplastischem Packungsmaterial ähnliche Wirkungen zu erreichen versucht, z. B. dadurch, daß man einen Packungsring aus Metall verwendete, der mit ringförmigen Einschnitten versehen war. vermöge deren er sich durch axiales Zusammendrücken unter Ausbeulung nach dem Rohr hin zusammenschieben ließ, wobei er sich mit dem ausgebeulten Teil in die Rohrwand eindrückte. Gegenüber der vorliegenden Rohrverbindung hat diese Verbindung jedoch den Nachteil, daß das Packungsmaterial besonders vorbereitet werden muß. und daß man den verbogenen Metallring nicht mehr aus der Muffe herausbekommen und wieder verwenden kann, dai.! ferner der dichte Schluß, verlorengeht, wenn die Verbindungen Dehnungen ausgesetzt sind, während das plastische Packungsmaterial jederzeit wieder verwendet werden kann und auch bei auftretenden Dehnungen einen dauernd dichten Abschluß sichert.Mau already has similar effects with non-plastic packing material tried to achieve z. B. by using a metal packing ring, which was provided with ring-shaped incisions. by virtue of which it is compressed by axial compression let push together with a bulge towards the tube, where he pressed into the pipe wall with the bulged part. Compared to the present Pipe connection, however, this connection has the disadvantage that the packing material must be specially prepared. and that you can no longer get the bent metal ring out of the socket and can use again dai.! furthermore, the tight seal is lost when the connections Strains are exposed, while the plastic packing material again at any time can be used and a permanent seal even when stretching occurs Closing secures.

Die Zeichnung stellt ein Ausführungsbeispiel der neuen Rohrverbindung mit einer Anschlul.imuffc für zwei gleichachsige Rohre dar. Die Enden 3 und 4 der zu verbindenden Rohre 1 und 2 sind in die Muffe 5 eingeführt, deren Bohrung in der Mitte bei 6 dem äußeren Rohrdurchmesser entspricht. Auf die mit Außenge\vinde 7 und S versehenen Enden der Muffe sind von den Rohren durchsetzte Überwurfmuttern Q und 10 aufgeschraubt. Tn die erweiterten Enden der Muffe 5 sind ziemlich lauge Ringe 11. 12 eingesetzt, die die Zwischenräume zwischen der Muffe und den Rohren ausfüllen. Die inneren Enden 13. 14 dieser Ringe und die Böden 15. 16 der Muffenzwischenräume sind in entgegengesetztem Sinne so abgeschrägt, daß die Flächen 13. 15 einerseits und 14. 10 anderseits keilförmige Ringräume mit nach innen gerichteten Keilrücken bilden. In diesen Ringräumen sind Packungen 17. 18 aus plastischem Material untergebracht. Die Flächen 13. 14. 15. 10 bilden gegen eine senkrecht zur Rohrachse stehende Ebene Winkel von etwa 45".The drawing represents an embodiment the new pipe connection with a connection imuffc for two coaxial pipes. The ends 3 and 4 of the pipes 1 and 2 to be connected are inserted into the socket 5, whose hole in the middle at 6 corresponds to the outer pipe diameter. On the with The ends of the socket with external threads 7 and S are penetrated by the pipes Union nuts Q and 10 screwed on. Tn are the enlarged ends of the sleeve 5 pretty lye rings 11. 12 used that the Fill in the gaps between the socket and the pipes. The inner ends 13. 14 these rings and the bottoms 15. 16 of the Socket gaps are in opposite Meaning beveled so that the surfaces 13.15 on the one hand and 14.10 on the other hand wedge-shaped Form annular spaces with inwardly directed wedge backs.

Dadurch wird ein GleitenWhen tightening z. B. the mother g, the ring 11 presses the pack 17 together. As a result of the strong inclination of the surfaces 13, 15, the plastic packing 11 is pressed very strongly against the tube 1 and produces a rinsiförmiiie indentation 19 at the pressure point in the latter. This results in sliding
