Description
Die Erfindung betrifft eine Schiebemuffe, insbesondere für Temperaturschwankungen ausgesetzte Kunststoffleitungen, mit zwei koaxialen, axial in bezug aufeinander verschiebbaren Rohren, die je an eines von zwei durch die Muffe miteinander zu verbindenden Leitungsrohre anzuschließen sind, wobei das innere Rohr an seinem Ende mit einer elastischen Manschette versehen ist, deren freies Ende mit leichtem Druck an der Innenfläche des äußeren Rohres anliegt.The invention relates to a sliding sleeve, in particular for temperature fluctuations Plastic lines, with two coaxial tubes which can be moved axially with respect to one another and which are each attached to one of two conduit pipes to be connected to one another by the socket are to be connected, with the inner tube is provided at its end with an elastic sleeve, the free end of which with light pressure on the inner surface of the outer tube.
Bekannte Schiebemuffen dieser Art sind an den freien Enden des äußeren Rohres entweder überhaupt nicht abgedichtet und geführt bzw. sie sind starr geführt, so daß insbesondere bei Abwinkelungen der ineinandergreifenden Rohre Verunreinigungen von außen zwischen die Rohre gelangen können bzw. bei Abwinkelungen ein Verklemmen der Rohre auftreten kann.Known sliding sleeves of this type are either at the free ends of the outer tube not sealed and guided or they are rigidly guided, so that especially with bends of the interlocking pipes, contaminants from the outside can get between the pipes or jamming of the pipes can occur with bends.
Der Erfindung liegt die Aufgabe zugrunde, eine Schiebemuffe der eingangs genannten Art so aus- so zubilden, daß die Abdichtung und Führung der Rohre auch bei Abweichungen von der Rohrfluchtung gewährleistet ist.The invention is based on the object of providing a sliding sleeve of the type mentioned at the beginning zubilden that the sealing and guidance of the pipes even with deviations from the pipe alignment is guaranteed.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das äußere Rohr eine einschiebbare elastisehe Muffe aufweist, deren freies Ende mit leichtem Druck an der Außenfläche des inneren Rohres anliegt. According to the invention, this object is achieved in that the outer tube is a retractable elastic tube Has sleeve, the free end of which rests with slight pressure on the outer surface of the inner tube.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes im vertikalen Längsschnitt dargestellt.The drawing shows an embodiment of the subject matter of the invention in vertical longitudinal section shown.
Die dargestellte Schiebemuffe weist zwei koaxiale, in bezug aufeinander in axialer Richtung verschiebbare Rohre 1 und 2 auf, die aus Kunststoff, z. B. Polyvinilchlorid oder Polyäthylen, bestehen. Am linken Ende des äußeren Rohres ist eine elastische Muffe 5 befestigt. Die ebenfalls aus Kunststoff bestehende Muffe 5 weist etwa in ihrer Mitte eine äußere, ringförmige Schulter 6 auf, die an der linken Stirnfläche des Rohres 1 anliegt. Ferner weist die Muffe 5 an ihrem inneren Ende noch eine kleinere, äußere Ringschulter 7 auf, die eine innere Ringschulter 8 des Rohres 1, hinter welcher dieses Rohr 1 eine ringförmige Einbuchtung 9 hat, hintergreift. Zwischen seinem linken Ende und der Schulter 8 ist die Innenfläche 10 des Rohres 1 leicht konisch, so daß ihr Durchmesser auf die Schulter 8 hin abnimmt. Die Innenfläche 11 der Muffe 5 ist ebenfalls konisch, so daß das freie Muffenende 12 auf dem inneren Rohr 2 liegt, während das rechte Muffenende 13 einen gewissen Abstand von dem Rohr 2 hat. Um die Elastizität der Muffe 5 zu erhöhen, kann dieselbe mit einem kurzen Schlitz 14 versehen sein, der sich von ihrem äußeren Ende 12 in axialer Richtung erstreckt.The sliding sleeve shown has two coaxial ones that can be displaced in the axial direction with respect to one another Pipes 1 and 2 made of plastic, e.g. B. polyvinyl chloride or polyethylene exist. On the left An elastic sleeve 5 is attached to the end of the outer tube. The one also made of plastic Sleeve 5 has an outer, annular shoulder 6 approximately in the middle, which is on the left The end face of the tube 1 rests. Furthermore, the sleeve 5 has at its inner end a smaller, outer annular shoulder 7, which has an inner annular shoulder 8 of the tube 1, behind which this tube 1 a has annular indentation 9, engages behind. Between its left end and the shoulder 8 is the Inner surface 10 of the tube 1 is slightly conical so that its diameter decreases towards the shoulder 8. the The inner surface 11 of the socket 5 is also conical so that the free socket end 12 rests on the inner pipe 2 lies, while the right socket end 13 has a certain distance from the pipe 2. About the elasticity To increase the sleeve 5, the same can be provided with a short slot 14 extending from its outer end 12 extends in the axial direction.
Die Muffe 5 wird nach dem Einbringen des Rohres 2 in das Rohr 1 montiert, indem sie auf das Rohr 2 aufgeschoben und nach rechts gedrückt wird. Dabei gleitet die elastisch nachgebende Schulter 8 auf der konischen Fläche 10, bis sie in die Einbuchtung 9 einschnappt, während zugleich die Schulter 6 auf das Ende des Rohres 1 trifft.The sleeve 5 is installed after the pipe 2 has been inserted into the pipe 1 by placing it on the Tube 2 is pushed on and pushed to the right. The elastically yielding shoulder 8 slides open the conical surface 10 until it snaps into the indentation 9, while at the same time the shoulder 6 on the The end of the tube 1 hits.
Das innere Rohr 2, das bei der Montage der Rohrleitung an ein Leitungsrohr 15 angeschweißt werden kann, ist an seinem im Rohr 1 befindlichen Ende mit einer angeschweißten, elastischen Manschette 16 versehen. Die Manschette 16 kann außen zwei ringförmige Schultern 17 und 18 aufweisen, die eine breite Ringnut 19 begrenzen, in der sich ein Dichtungsring 20 von kreisförmigem Querschnitt (O-Ring) befindet. Von der Schulter 18 aus erweitert sich die Außenfläche 21 der Manschette 16 konisch bis zu ihrem freien Ende 22, das an der Innenfläche des äußeren Rohres 1 anliegt.The inner pipe 2, which is welded to a conduit pipe 15 when the pipeline is assembled can, is provided with a welded, elastic sleeve 16 at its end located in the tube 1. The cuff 16 can have two annular shoulders 17 and 18 on the outside, which one limit wide annular groove 19 in which a sealing ring 20 of circular cross-section (O-ring) is located. From the shoulder 18, the outer surface 21 of the sleeve 16 widens conically up to its free end 22, which rests against the inner surface of the outer tube 1.
Die Manschette 16 kann ebenfalls mit einem kurzen Längsschlitz 23 versehen sein, um die Elastizität zu erhöhen.The cuff 16 can also be provided with a short longitudinal slot 23 in order to increase the elasticity to increase.
