Description
Die Erfindung bezieht sich auf eine Rohrdichtung, bestehend aus einem Grundring und zwei von dem Grundring vorstehenden Lappen für eine Steckverbin dung für thermoplastische Rohre gemäß dem Oberbe griff des Hauptanspruches.The invention relates to a pipe seal, consisting of a base ring and two of the Basic ring protruding tab for a connector for thermoplastic pipes according to the Oberbe handle the main claim.
Die bei der Sanierung von schadhaften Kanalisationen eingesetzten Kunststoffrohre müssen dann, wenn sie ohne Freilegen der Kanalisationsleitungen in diese Kanalisationsrohre eingezogen werden sollen, beson dere Bedingungen erfüllen, nämlich sie müssen im Gegensatz zur üblichen Muffenverbindung im Bereich der Muffenverbindung einen Außenumfang aufweisen, der dem Außenumfang des übrigen Bereiches des Rohres entspricht. Da auch der Innendurchmesser in diesem Bereich gleich dem Innendurchmesser des übrigen Rohrteiles sein muß, entstehen Tür die Einsteck- und Muffenverbindungen erhebliche Schwierigkeiten, wenn eine absolute Dichtigkeit der miteinander verbun denen Rohre in diesem Bereich in üblicher Weise verlangt wird. Aus dem DE-GM 86 03 628 ist eine solche, auch im Muffen- und Einsteckbereich gleichen Außendurchmesser aufweisende Steckverbindung be kannt, wobei die Verriegelung der beiden miteinan der zu verbindenden Rohre dadurch erfolgt, daß sich über den gesamten Umfang der Muffe eine Klaue er streckt, die aus der Rohrwand herausgearbeitet ist, wobei diese Klaue federnd in eine Aussparung ein rastet, die sich über den gesamten Umfang des Ein steckendes erstreckt. Die Abdichtung erfolgt durch einen Rollring.The in the renovation of damaged sewers Plastic pipes must be used if they without exposing the sewer pipes to them Sewer pipes to be drawn in, esp other conditions, namely they must Contrary to the usual socket connection in the area the sleeve connection has an outer circumference, the outside circumference of the rest of the tube corresponds. Because also the inside diameter in this Area equal to the inside diameter of the rest Tube part must be, the insert and door arise Socket connections pose considerable difficulties, though an absolute tightness of the interconnected which pipes in this area in the usual way is required. From DE-GM 86 03 628 is one such, even in the socket and insert area Connector with outer diameter be knows, with the locking of the two miteinan of the pipes to be connected takes place in that a claw over the entire circumference of the sleeve stretches, which is worked out of the pipe wall, this claw resiliently into a recess snaps across the entire circumference of the one stuck stretches. The seal is made by a rolling ring.
Es sind auch gattungsbildende Rohrdichtungen aus der US-PS 30 46 028 bekannt, die mit von einem Grundring schräg nach oben vorstehenden Lappen ausgerüstet sind, wobei aber diese gattungsbildenden Rohrdich tungen nicht bei Rohren eingesetzt werden, die im Bereich von Einsteckende und Muffenende gleichen Außendurchmesser wie im übrigen Rohrbereich aufwei sen.There are also generic pipe seals from the US-PS 30 46 028 known with a base ring rag protruding diagonally upwards are, but these generic Rohrdich are not used for pipes that are in the The area of the insertion end and the socket end are the same Outside diameter as in the rest of the pipe area sen.
Der Erfindung liegt die Aufgabe zugrunde, eine Rohrdichtung zu schaffen, die ohne einen exzessiven Druck auf das relativ dünnwandige Muffenteil eine gute Abdichtung dieses Bereiches bewirkt.The invention has for its object a To create pipe gasket without an excessive Pressure on the relatively thin-walled sleeve part one good sealing of this area.
Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des kennzeichnenden Teils in Ver bindung mit dem Gattungsbegriff des Hauptanspruches gelöst.This object underlying the invention will through the teaching of the characteristic part in ver binding with the generic term of the main claim solved.
Vorteilhafte Ausgestaltungen sind in den Unteran sprüchen erläutert.Advantageous configurations are in the Unteran sayings explained.
Mit anderen Worten ausgedrückt wird vorgeschlagen, daß die beiden von dem Grundring vorstehenden Lappen in besonderer Weise ausgebildet sind, nämlich daß der in Einsteckrichtung des Einsteckendes gesehen erste Lappen eine größere Dicke aufweist als der in Einsteckrichtung des Einsteckendes gesehen zweite Lappen und daß darüber hinaus der erste Lappen stei ler gestellt ist als der zweite Lappen. Dadurch wird der Hauptdruck auf die Innenwandung des Muffenteiles möglichst nahe an den normalen Rohrwandquerschnitt im Bereich der Verbindung verlagert, so daß ein un gewolltes Aufspreizen des Muffenendes vermieden wird. In other words, it is suggested that the two tabs protruding from the base ring are trained in a special way, namely that seen in the insertion direction of the insertion end first flap has a greater thickness than that in Insertion direction of the insertion end seen second Rag and beyond that the first rag sticks is more than the second cloth. This will the main pressure on the inner wall of the socket part as close as possible to the normal pipe wall cross section shifted in the area of the connection, so that an un deliberate spreading of the socket end avoided becomes.
Ein Ausführungsbeispiel der Erfindung wird nachfol gend anhand der Zeichnung erläutert. Die Zeichnung zeigt dabei inAn embodiment of the invention will follow explained using the drawing. The drawing shows in
Fig. 1 den Teil eines Einsteckendes und den Teil eines Muffenendes im auseinan dergezogenen Zustand und in Fig. 1 shows the part of a male end and the part of a sleeve end in the dergezogene state and in
Fig. 2 in größerem Maßstab einen Schnitt durch die eigentliche Dichtung. Fig. 2 on a larger scale a section through the actual seal.
In Fig. 1 ist ein Muffenende 1 und ein Einsteckende 2 dargestellt, wobei das Muffenende 1 eine Riegel hinterschneidung 3 aufweist, die hinter einen am Einsteckende 2 vorgesehenen Riegelvorsprung 4 grei fen kann, wenn das Muffenende 1 auf das Einsteck ende 2 aufgeschoben wird bzw. das Einsteckende 2 in das Muffenende 1 eingeschoben wird.In Fig. 1, a socket end 1 and a shank 2 is illustrated, wherein the socket end 1 undercut a bolt 3 which can fen grei behind a provided at the insertion end 2 locking projection 4, if the socket end 1 on the male end 2 is slid or the insertion end 2 is inserted into the socket end 1 .
Das Einsteckende 2 weist außerdem eine umlaufende Ausnehmung 16 auf, in die eine bandartige Ringdich tung 5 eingelegt ist.The insertion end 2 also has a circumferential recess 16 into which a band-like ring sealing device 5 is inserted.
Die genaue Ausbildung der Dichtung 5 geht deutlicher aus Fig. 2 hervor und es ist erkennbar, daß die Dichtung 5 aus einem Grundring 6 besteht, an dem materialeinheitlich aus dem Werkstoff des Grund ringes 6 Lappen 7 und 8 ausgeformt sind. Der Lappen 8 ist dabei der in Einsteckrichtung des Ein steckendes 2 gesehen erste Lappen und weist eine größere Stärke d1 auf als die Stärke d2 des Lappens 7. Auch ist die Neigung der Oberseite 11 des Lappens 8 gegenüber der Rohrachse A größer, d. h. dieser Lappen 8 ist steiler gestellt und bildet mit der Rohrachse A einen Winkel α etwa in der Größenord nung zwischen 40 und 45°, während der von dem Lappen 7 mit der Rohrachse A eingeschlossenen Winkel β nur zwischen 30 und 35° groß ist.The exact design of the seal 5 is clearer from Fig. 2 and it can be seen that the seal 5 consists of a base ring 6 , on the material ring from the material of the base ring 6 tabs 7 and 8 are formed. The flap 8 is the first flap seen in the direction of insertion of a stuck 2 and has a greater thickness d 1 than the thickness d 2 of the flap 7 . Also, the inclination of the top 11 of the flap 8 relative to the tube axis A is greater, that is, this flap 8 is steeper and forms an angle α with the tube axis A approximately in the order of magnitude between 40 and 45 °, during that of the flap 7 with the tube axis A included angle β is only between 30 and 35 °.
Das freie Ende 9 des Lappens 7 und das freie Ende 10 des Lappens 8 sind im wesentlichen rechteckig aus gebildet, laufen also nicht wie an sich sonst bei Lippendichtungen spitz zu und die Wurzel des Lappens 8 im Bereich des Grundringes 6 ist ausgenommen, so daß ein Freiraum 14 entsteht, in den sich, wenn die Dichtung 5 zusammengepreßt wird, ein Teil der Unter seite des Lappens 8 einpreßt.The free end 9 of the flap 7 and the free end 10 of the flap 8 are substantially rectangular, so they do not taper as is otherwise the case with lip seals and the root of the flap 8 in the region of the base ring 6 is excluded, so that a Free space 14 is formed, in which, when the seal 5 is pressed together, part of the underside of the tab 8 is pressed.
Im zusammengepreßten Zustand der Dichtung 5 ragt das freie Ende 9 des Lappens 7 nicht über das freie Ende 15 des Grundringes 6 vor.In the compressed state of the seal 5 , the free end 9 of the tab 7 does not protrude beyond the free end 15 of the base ring 6 .
