Description

Die Verwendung von elastischen, walzenförmigen Gummiringen für die Dichtung von Muffenrohren, sei es für Gas- oder für Wasserrohrleitungen, ist bekannt. Gemäß der Abb. 1 wird hierbei auf das Schwanzende α eines normalen Muffenrohres ein Gummiring aufgelegt, dann wird das Schwanzende in das Muffenrohr gemäß der Abb. 2 eingeschoben, wobei der Gummiring b sich abrollt, sich breitquetscht und schließlich durch sein elastisches Verhalten die Dichtung bewirkt. Bei Saug- oder Heberleitungen, die unter einem Unterdruck (Vakuum) stehen, kann der Gummiring niemals in das Innere c der Rohrleitung gelangen, selbst wenn er sich verschieben sollte; denn das Schwänzende des Rohres α stößt gegen die Einschnürung e der Muffe d; der verbleibende Zwischenraum f wird hierbei so gering, daß sich der Gummi-The use of elastic, cylindrical rubber rings for sealing socket pipes, be it for gas or water pipelines, is known. According to Fig. 1, a rubber ring is placed on the tail end α of a normal socket pipe, then the tail end is pushed into the socket pipe according to Fig. 2, whereby the rubber ring b unrolls, squeezes and finally causes the seal due to its elastic behavior . In the case of suction or siphon lines that are under a negative pressure (vacuum), the rubber ring can never get into the interior c of the pipeline, even if it should shift; because the tail end of the pipe α strikes against the constriction e of the socket d; the remaining space f becomes so small that the rubber

ao ring nicht durch ihn hindurchquetschen kann. Steht jedoch das Rohr selbst unter einem hohen überdruck, dann kann der Gummiring b herausgepreßt werden, denn der Zwischenraum g wäre gemäß der Abb. 2 genügend groß. Es müßte darum ein besonderer Sicherungsring vorgesehen werden, wie es! vielfach geschieht, wodurch jedoch die Dichtung verteuert wird. Ungesicherte Gummiringe finden aus diesem Grunde meist nur Verwendung für Unterdruckleitungen. Es gelingt jedoch, die Haftspannung des Gummiringes b, dessen Oberfläche meist glatt ist, erheblich zu vermehren, dadurch, daß die Oberfläche mit rillenartigen Vertiefungen h versehen wird, was durch Abb. 3 verdeutlicht wird. Die An-Ordnung, die Form und die Anzahl der Vertiefungen h können hierbei beliebig gewählt werden, jedoch müssen sie voneinander getrennt sein. Wird der Gummiring b eingewulstet, dann pressen sich die anfänglich mit Luft erfüllten Vertiefungen so stark an die anliegenden Wandungen, daß die Luft aus ihnen verschwinden muß. Es entsteht dann eine sehr starke Saugwirkung, wodurch die Haftwirkung des Ringes an eisernen Wandüngen im Muffeninnern begünstigt wird; denn es drückt jetzt die Außenluft mit ihrem natürlichen Druck auch auf den Gummiring. Das Herauspressen des Ringes b aus dem Muffeninnern wird dadurch, wenn auch nicht unmöglich gemacht, so doch wesentlich erschwert. ao ring cannot squeeze through it. However, if the pipe itself is under a high overpressure, then the rubber ring b can be pressed out, because the gap g would be sufficiently large according to FIG. 2. A special locking ring would therefore have to be provided, like it! happens many times, but this makes the seal more expensive. For this reason, unsecured rubber rings are usually only used for vacuum lines. However, it is possible to considerably increase the adhesive tension of the rubber ring b, the surface of which is mostly smooth, by providing the surface with groove-like depressions h , which is illustrated in FIG. The arrangement, the shape and the number of depressions h can be selected as desired, but they must be separated from one another. If the rubber ring b is beaded, then the depressions, which are initially filled with air, are pressed so strongly against the adjacent walls that the air has to disappear from them. There is then a very strong suction effect, which promotes the adhesion of the ring to iron walls inside the socket; because the outside air now presses the rubber ring with its natural pressure. The pressing out of the ring b from the inside of the socket is thereby, if not made impossible, at least made considerably more difficult.
