Description
Dichtungsmanschette für Muffenverbindungen Die Erfindung bezieht sich auf eine Dichtung, vorzugsweise aus Kunststoff, z. B. aus Polyäthylen, für eine Muffenverbindung, insbesondere für Abwasserrohre aus Stahl, die zwischen dem glatten Einsteckrohrende und der Muffe angeordnet ist und aus einer auf das glatte Einsteckrohrende aufgezogenen, an der Außenseite mindestens aus einem Teil ihrer Länge mit schmalen ringförmigen Dichtlippen versehenen Manschette besteht, welche an dem einen Ende mit einem ringförmigen Innenvorsprung sich gegen die Stirnfläche des Einsteckrohrendes abstätzt und an dem anderen Ende einen das Muffenende schalenförmig umfassenden Flansch aufweist.Sealing sleeve for socket joints The invention relates to on a seal, preferably made of plastic, e.g. B. made of polyethylene, for a Sleeve joint, especially for steel sewer pipes, between the smooth Einsteckrohrende and the sleeve is arranged and from one to the smooth Einsteckrohrende raised, on the outside at least part of its length with narrow annular sealing lips provided cuff, which at one end with an annular inner projection against the face of the plug-in pipe end and at the other end a shell-shaped encompassing the sleeve end Has flange.
Erfindungsgemäß wird diese bekannte Verbindung dadurch verbessert, daß der ringförmige Innenvorsprung eine sich zur Manschettenmitte hin erstreckende Umbördelung aufweist, durch die eine Ringnut gebildet ist, in die die Stirnfläche des Einsteckendes eingeführt ist und die diese Stirnfläche abdichtend übergreift.According to the invention, this known connection is improved by that the annular inner projection extends towards the center of the sleeve Has flanging through which an annular groove is formed into which the end face of the insertion end is inserted and which engages over this end face in a sealing manner.
Der Vorteil dieser neuen Anordnung ergibt sich aus folgenden Überlegungen: Bei der Montage derartiger Verbindungen tritt des öfteren der Fall ein, daß das Einsteckende eines Rohres gekürzt werden muß. In diesem Fall wird der Korrosionsschutz an der Stirnfläche des Rohres entfernt, und es ist am Montageort nicht möglich, die entblößte Fläche mit einer Schutzschicht zu versehen. Um diesen Mangel zu beheben, wird das Dichtungselement an seinen Einsteckenden mit einem in den Innenraum des Rohres hineingreifenden Rand versehen. Das Einsteckende des Dichtungselementes wird dadurch ringnutförmig gestaltet. Wird bei der Montage das Dichtungselement auf das Einsteckende des Rohres geschoben, so dringt die Stirnfläche des Rohrendes in diese Ringnut ein und umschließt diese derart, daß sie gegen den Angriff von korrodierenden Mitteln geschützt ist. Zu diesem Zweck ist die lichte Weite der Ringnut zweckmäßig so gehalten, daß eine gewisse Vorspannung in Schließrichtung entsteht. Eine weitere vorteilhafte Wirkung der Ringnut ist darin zu sehen, daß sie als Ausdehnungsraum wirkt, der eine gewisse Beweglichkeit des eingesteckten Rohrendes in Längsrichtung ermöglicht.The advantage of this new arrangement results from the following considerations: When assembling such connections it often occurs that the The spigot end of a pipe must be shortened. In this case, the corrosion protection removed from the face of the pipe, and it is not possible at the installation site to provide the exposed area with a protective layer. To remedy this deficiency, is the sealing element at its insertion ends with a in the interior of the Provided pipe reaching edge. The insertion end of the sealing element is thus designed in the shape of an annular groove. If the sealing element is attached to the Pushing the insertion end of the pipe, the end face of the pipe end penetrates into it A ring groove and encloses it in such a way that it protects against the attack of corrosive Funds is protected. The clear width of the annular groove is useful for this purpose held so that a certain bias arises in the closing direction. Another The advantageous effect of the annular groove can be seen in the fact that it acts as an expansion space acts that a certain mobility of the inserted pipe end in the longitudinal direction enables.
Der Gegenstand der Erfindung ist in der Zeichnung in einem Längsschnitt dargestellt. Auf das glatte Einsteckrohrende 1 ist die Dichtungsmanschette 2 aufgezogen. Diese besteht aus einer Hülse aus Polyäthylen od. dgl. und hat an dem im Innern der Rohrverbindung liegenden Ende einen ringförmigen Innenvorsprung 3 mit einer sich zur Manschettenmitte hin erstreckenden Umbördelung 3 a und mit einem Flansch 4 am anderen Ende. An der Außenseite ist die Manschette 2 mit schmalen Dichtlippen 5 versehen. Durch die Umbördelung 3 wird eine Ringnut 6 geschaffen, in der das Ende des Einsteckrohres 1 abgedichtet liegt. Das Muffenrohr ist mit 7 bezeichnet.The object of the invention is shown in the drawing in a longitudinal section. The sealing sleeve 2 is pulled onto the smooth plug-in pipe end 1. This consists of a sleeve made of polyethylene or the like. At the end lying inside the pipe connection has an annular inner projection 3 with a flange 3 a extending towards the center of the cuff and with a flange 4 at the other end. The cuff 2 is provided with narrow sealing lips 5 on the outside. Through the bead 3, an annular groove 6 is created, in which the end of the plug-in tube 1 is sealed. The socket pipe is denoted by 7.
