Description
Die Erfindung betrifft eine Kupplung für Kunststoffrohr, bestehend aus einer Kunststoffmuffe, die über zwei miteinander zu verbindenden Rohrenden greifen kann, wobei die beiden Muffenden eine Erweiterung haben mit innen, wo die Erweiterung beginnt, einer Radialnut, in die sin Gummiabdichtungsring aufgenommen werden kann, der durch einen unzusammendrUckbaren Klemmring, der teils gegen die Innenwand der Muffe anliegt, fixiert wird.The invention relates to a coupling for plastic pipe, consisting of a plastic sleeve that connects to each other via two to be connected pipe ends can grip, whereby the two socket ends have a widening with inside, where the widening begins, a radial groove in which a rubber sealing ring can be received, which is fixed by an incompressible clamping ring, which partly rests against the inner wall of the socket will.
Das Prinzip einer solchen Rohrkupplung ist u. a. aus der NL-PS 6805559 bekannt. Ein Nachteil der beschriebenen Rohrkupplung ist, daß die ganze Konstruktion ziemlich kompliziert und die Befestigung des Klemmrings ziemlich umständlich ist. Bei dieser Art von Rohrkupplungen ist der Abdichtungsring aus einem Stück gefertigt. Die Radialnut ist aus der NL-PS 7600928 bekannt. Die vorerwähnten Muffen sind im Handel erhältlich.The principle of such a pipe coupling is inter alia. known from NL-PS 6805559. A disadvantage of the pipe coupling described is that the whole construction is rather complicated and the attachment of the clamping ring is rather cumbersome. At this Type of pipe coupling, the sealing ring is made from one piece. The radial groove is known from NL-PS 7600928. The aforementioned sleeves are commercially available.
Die Aufgabe der Erfindung ist es, eine Rohrkupplung zu schaffen, bei der der Abdichtungsring einfach und mithin billig zu montieren ist. Eine weitere Aufgabe ist es, den Ring so auszubilden, daß er in montiertem Zustand leicht verschiedenen Rohrdurchmessern angepaßt werden kann.The object of the invention is to create a pipe coupling, in which the sealing ring is easy and therefore cheap to assemble. Another object is to design the ring so that it can easily be adapted to different pipe diameters in the assembled state.
Erfindungsgemäß wird dies dadurch erreicht, wenn der Abdichtungsring im Querschnitt T-förmig ist, und zwar so, daß ein Bein in montiertem Zustand nach innen gerichtet ist und ein Arm in die Radialnut der Muffe hineingreift, während ein zweiter Arm vom Klemmring gegen die Innenwand der Erweiterung derAccording to the invention this is achieved when the sealing ring is T-shaped in cross section, in such a way that a Leg is directed inward in the assembled state and one arm engages in the radial groove of the sleeve, while a second arm from the clamping ring against the inner wall of the extension of the
Muffe eingeschlossen wird. Der zweite Arm hat vorzugsweise einen Radialnocken, der in eine Radialnut des Klemmrings hineingreift, wodurch der Abdichtungsring besser fixiert wird. Auch kann ein Radialnocken des Klemmrings in eine Radialnut des Abdichtungsrings hineingreifen.Sleeve is included. The second arm preferably has a radial cam which engages in a radial groove of the clamping ring, whereby the sealing ring is better fixed. A radial cam of the clamping ring can also be inserted into a radial groove of the sealing ring.
Der Klemmring wird an das Ende der Erweiterung der Muffe fixiert. Dies kann dadurch geschehen, daß der Klemmring geklebt oder geklemmt wird oder das Ende der Erweiterung nach innen umgebördelt wird. Dadurch wird nach Montage des Abdichtungs- und des Klemmrings im Ende der Muffe ein Ganzes erhalten, wodurch ein Verlorengehen der einzelnen Teile während des Transports vermieden wird.The clamping ring is fixed to the end of the extension of the socket. This can be done in that the clamping ring is glued or clamped or the end of the extension is beaded inwards. This is after assembly of the sealing ring and the clamping ring received a whole at the end of the sleeve, which prevents the individual parts from getting lost during transport will.
Die Abdichtung kann Üblicherweise aus einem geschlossenen Ring bestehen, ist aber vorzugsweise ein Teil eines bandförmigen endlosen Profils aus Gummi oder einem anderen elastomeren Werkstoff, welcher Teil eine Länge gleich dem Innenumfang der Erweiterung am Muffenende hat. Dadurch, deß der Abdichtungsring ein Teil eines endlosen Profils ist, läßt er sich leicht verschiedenen Durchmessern der zu kuppelnden Rohre anpassen. Durch den Druck des Rohrs ist die Naht des Abdichtungsrings nach dem Kuppeln des Rohrs zu. Der Vorteil des erfindungsgemäßen Abdichtungsrings aus einem endlosen Profil ist, daß:The seal can usually consist of a closed ring consist, but is preferably a part of a belt-shaped endless profile made of rubber or another elastomeric material, which part has a length equal to the inner circumference of the extension at the socket end. Thereby the sealing ring is part of an endless profile, it can easily be adapted to different diameters of the pipes to be coupled. By the pressure of the pipe is the seam of the sealing ring after coupling the pipe to it. The advantage of the sealing ring according to the invention from an endless profile is that:
α) sich der Abdichtungsring jedem Durchmesser der zu kuppelnden Rohre aus demselben endlosen Profil an passen läßt;α) can fit pipes to be coupled out of the same endless profile of the seal ring each of the diameter;
b) sich die bandförmigen Abdichtungen vor der Montage in der Muffe leicht am Klemmring anbringen lassen;b) the tape-shaped seals before assembly in let the sleeve easily attach to the clamping ring;
c) sich die noch nicht montierten Abdichtungen leicht auf Lager halten lassen.c) the seals that have not yet been installed can easily be kept in stock.
Die Erfindung wird anhand einer Zeichnung erläutert. In der Zeichnung ist:The invention is explained with reference to a drawing. In the drawing is:
Fig. 1 ein T-förmiger Abdichtungsring im Querschnitt; Fig. 2 ein Klemmring im Querschnitt;1 shows a T-shaped sealing ring in cross section; 2 shows a clamping ring in cross section;
Fig. 3 eine erweiterte Muffe mit montiertem Klemm- und montiertem Abdichtungsring im Querschnitt;3 shows an expanded sleeve with an assembled clamping ring and an assembled sealing ring in cross section;
Fig. 4 der Querschnitt wie in der Fig. 3, jedoch jetzt mit gekuppeltem Rohrende.4 shows the cross section as in FIG. 3, but now with coupled pipe end.
Mit 1 ist ein Bein eines T-förmigen Abdichtungsrings bezeichnet, der einen Arm 2 und einen Arm 3 aufweist. Der Abdichtungsring hintergreift mit einem radialen Nocken 4 einen Klemmring 5, der dazu mit einer radialen Nut 6 ausgestattet ist.1 with a leg of a T-shaped sealing ring is referred to, which has an arm 2 and an arm 3. With a radial cam 4, the sealing ring engages behind a clamping ring 5, which is equipped with a radial groove 6 for this purpose.
Der Abdichtungsring wird in eine Muffe 7 eingesetzt, die dazu ein erweitertes Ende 8 aufweist. Im erweiterten Ende 8 der Muffe 7 sitzt eine Rcdialnut 9. Ein Rohrende 10 ist, wie Fig. 4 zeigt, in die Muffe 7 hineingeschoben und ein umgebördeltes Ende Π der Muffe 7 fixiert den Klemmring 5.The sealing ring is inserted into a sleeve 7 which has a widened end 8 for this purpose. In the extended end 8 of the Socket 7 sits a Rcdialnut 9. A pipe end 10 is how 4 shows it has been pushed into the sleeve 7 and a flanged end Π of the sleeve 7 fixes the clamping ring 5.
