Abstract
Description
Die Erfindung bezieht sich auf einen Dichtring für Steckmuffenverbindungen von rohrförmigen Körpern als Hausabfluß- und Kanalrohre, wobei ein elastischer Dichtring aus Kunststoff in einer nach innen offenen umlaufenden Nut als Standardsicke eines Rohres angeordnet ist und eine Dichtung zwischen der Innenseite eines Rohres und der äußeren Umfangsfläche eines in den Dichtring eingesetzten Rohres gebildet ist sowie der Dichtring durch ein in die Nut eingesetztes Basiselement gebildet ist, das in Einsteckrichtung schräg angestellte und durch das eingesteckte Rohr in Anstellrichtung verschwenkbare Dichtlippen aufweist und in Einsteckrichtung des Rohres mindestens eine Kompressionslippe ausgebildet ist.The The invention relates to a sealing ring for push-in joints of tubular bodies as Hausabfluß- and sewer pipes, wherein a plastic elastic sealing ring in an inwardly open circumferential groove as standard thickness of a Pipe is arranged and a seal between the inside a pipe and the outer peripheral surface of a formed in the sealing ring tube is formed as well as the sealing ring is formed by an inserted into the groove base element, the obliquely in the insertion direction employed and by the inserted tube in the direction of pivoting sealing lips has and in the insertion of the tube at least one compression lip is trained.
Ausbildungen dieser Art sind in vielfältiger Ausgestaltung bekannt geworden. Es hat sich aber gezeigt, daß es relativ aufwendig ist, mit einem Dichtring einen hohen Ausfüllungsgrad einer Standardsicke bei großer Dichtwirkung herzustellen. Hierbei besteht oftmals der Mangel, daß die verwendeten Materialien für derartige Dichtringe hohe Kosten verursachen und die Wurzelfestigkeit in der Sicke nicht gegeben ist.training This type are in a variety of configurations known. However, it has been shown that it is relatively expensive, with a sealing ring a high degree of filling a standard thickness at big Make sealing effect. Often there is the defect that the used Materials for Such seals cause high costs and root resistance in the bead is not given.
Es ist auch bekannt, Versteifungsringe in die Dichtung zu integrieren. Hierbei treten Montageaufwendungen bei der Erstellung der Dichtung auf und es müssen entsprechende Bemessungen berücksichtigt werden, die eine genaue Positionierung in der Sicke ermöglichen.It It is also known to incorporate stiffening rings in the gasket. This assembly costs occur when creating the seal up and it must appropriate dimensions are taken into account which allow accurate positioning in the bead.
Die Aufgabe der Erfindung ist es, eine ökonomische Ausbildung eines gattungsgemäßen Dichtringes mit Minimierung von hochwertigem Dichtwerkstoff zu schaffen, der eine einfache Herstellung mit einem hohen Füllungsgrad der Sicke aufweist.The The object of the invention is to provide an economical training of a generic sealing ring with minimization of high quality sealing material to create the has a simple production with a high degree of filling of the bead.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß dadurch, daß der Dichtring aus einem Dichtelement in Form von hochwertigem elastomeren Kunststoff, wie TPE, TPU oder einem Elastomer als Teilelement besteht, das einen durch den Dichtwerkstoff mindestens teilweise umschlossenes Endstück aus einem härteren Kunststoff, wie PP, aufweist, wobei das Endstück des eingesetzten Dichtringes mit seinem freien Endbereich ohne Dichtwerkstoff am Dichtungsanfang in Einsteckrichtung des Rohres der Sicke zugeordnet ist.The solution This object is achieved according to the invention in that the sealing ring from a sealing element in the form of high quality elastomeric plastic, as TPE, TPU or an elastomer as a sub-element, the one by the sealing material at least partially enclosed end of a tougher Plastic, such as PP, having the end of the inserted sealing ring with its free end without sealing material at the beginning of the seal assigned in the insertion of the tube of the bead.
Hierdurch ist es möglich, den Anteil des hochpreisigen Dichtwerkstoffs für einen funktionsfähigen Dichtring zu minimieren.hereby Is it possible, the proportion of the high-priced sealing material for a functional sealing ring to minimize.
Zusätzlich wird als Ausgestaltung vorgeschlagen, daß die unterschiedlichen Werkstoffe von Dichtbereich und Kern als Zweikomponenten-Verbindung miteinander verbunden sind.In addition will proposed as an embodiment that the different materials of sealing area and core as a two-component connection with each other are connected.
Zur Erleichterung der Montage ist vorgesehen, daß in den Dichtwerkstoff ein Gleitmittel eingelagert ist, das an der Oberfläche einen Gleitfilm ausbildet.to Facilitating the assembly is provided that in the sealing material Lubricant is incorporated, which forms a lubricating film on the surface.
Eine vorteilhafte Ausgestaltung besteht darin, daß das Endstück einen winkelförmigen Querschnitt aufweist, wobei ein Schenkel den außenliegenden Endbereich am Dichtungsanfang bildet, während der andere Schenkel durch den Dichtwerkstoff umschlossen ist.A advantageous embodiment is that the tail has an angular cross-section having a leg of the outer end region on Seal start forms while the other leg is enclosed by the sealing material.
Ferner wird vorgeschlagen, daß das Endstück einen Rezeß zur Aufnahme für einen Herstellungsprozeß aufweist.Further It is suggested that the tail a recess to Recording for has a manufacturing process.
