Description
: ■ rif: ■ rif
Für dünnwandige schmiedeeiserne Rohre von großer Lichtweite hat man schon vorgeschlagen, den ganzen Muffengrund konisch auszubilden, um Unrundheiten des eingeschobenen Spitzendes auszugleichen und eine Anlage der Stirnfläche des Spitzendes über den vollen Kreis am Muffengrund zu gewähr-' leisten.For thin-walled wrought-iron pipes with a large clear width, it has already been proposed that to make the entire socket base conical in order to compensate for out-of-roundness of the inserted spigot end and a system to ensure the face of the spigot over the full circle at the socket base Afford.
Weiterhin hat man bereits in den Muffen von Tonrohren am vorderen Ende der Muffen Führungsrippen angeordnet, die nach dem Muffenrand zu abgeschrägt sind und vor dem Muffengrund endigen, um das Einlegen einer Dichtung hinter den Führungsrippen in den Muffengrund vor dem Einschieben des Spitzendes zu ermöglichen. Abgesehen davon, daß diese flach und nicht kegelig abgeschrägten Führungsrippen nur als Widerlager für den Dichtungsring dienen und nur an einem Teil ao der Innenfläche der Muffe angeordnet sind, lassen sie sich bei mit Schraubringen ausgerüsteten Muffenverbindungen gußeiserner Rohre nicht verwenden, da in diesem Falle ja die Dichtung und die Stopfbüchse erst nach dem Einführen des Spitzendes in die Muffe in diese eingebracht werden.Furthermore, one has already in the sleeves of clay pipes at the front end of the sleeves Arranged guide ribs that are beveled after the socket edge and before End socket base to allow the insertion of a seal behind the guide ribs in the To enable socket base before inserting the spigot end. Besides that this flat and not conical beveled guide ribs only as an abutment for the Sealing ring are used and are only arranged on a part of the inner surface of the sleeve, they can be cast iron with socket connections equipped with screw rings Do not use pipes, as in this case the seal and the stuffing box are the first after the spigot has been inserted into the socket.
Die Erfindung besteht nun darin, daß bei gußeisernen Muffenrohren mit Stopfbüchsendichtung ein konisches selbstzentrierendes Auflager für das Spitzende des Nachbarrohres dadurch geschaffen wird, daß die an sich bekannten Zentrierrippen hinter der Dichtung angeordnet sind und nach dem Muffengrunde zu nach den Mantellinien eines Kegels verlaufen. Das Spitzende kommt also zur Zentrierung der Rohre zwecks leichten Einbringens der Dichtung und Einschraubens der Stopfbüchse nur punkt- bzw. stellenweise, nämlich an den schmalen kegelförmigen Rippen des Muffengrundes mit der Muffe zur Anlage, wohingegen infolge dieser Rippen keine volle Kreisanlage der Spitzenstirnfläche am Muffengrund stattfindet, wie dies bei den bekannten mit konischem Muffengrund ausgerüsteten Muffen schmiedeeiserner Rohre der Fall ist.The invention consists in that in cast iron socket pipes with a stuffing box seal a conical self-centering support for the spigot end of the adjacent pipe is created in that the on known centering ribs are arranged behind the seal and after the socket base to after the surface lines of a Cone run. The spigot comes to center the tubes for the purpose of easy Insertion of the seal and screwing in of the stuffing box only pointwise or in places, namely on the narrow conical ribs of the socket base with the socket to System, whereas as a result of these ribs there is no complete circular system of the tip end face takes place at the socket base, as is the case with the known ones with a conical socket base equipped sleeves of wrought iron pipes is the case.
Gegenüber solchen vollen Muffengrundzentrierkegelflächen haben die schmalen ko-. nisch gerichteten Zentrierrippen für Rohre aus gußeisernem Werkstoff den bedeutungsvollen Vorteil, daß in den verlegten Leitungen bei Auftreten starker Axialdrücke bzw. bei Auftreten von Richtungsabweichungen ein Hineinschieben des Spitzendes in die Muffe bzw. ein Einschwenken desselben in solchem Maße möglich ist, wie die Rippen und die gegenstoßenden Randstellen des Rohrspitzendes sich ineinander eindrücken bzw. deformieren können. Da die Zentrierrippen ihre zentrierende Aufgabe für das Einbringen und Anziehen der Dichtung erfüllt haben, so ist ihre nachträgliche Deformation in den verlegten Leitungen ohne Belang für die Betriebssicherheit der Rohrverbindung, zumal durch den Erfindungsgegenstand der Gefahr einer ernstlichen Beschädigung der Muffe oder des Spitzendes und der Gefahr des Auftretens von Undichtigkeiten in wirksamster Weise vorgebeugt ist.Compared to such full socket base centering conical surfaces have the narrow ko-. nically oriented centering ribs for pipes made of cast iron material are the most important Advantage that in the laid lines when strong axial pressures occur or when If deviations in direction occur, the spigot is pushed into the socket or a pivoting of the same is possible to the same extent as the ribs and the opposing edge points of the pipe spigot end press into one another or deform can. Since the centering ribs have performed their centering task for inserting and tightening the seal, their subsequent deformation in the laid lines is irrelevant for operational safety the pipe connection, especially because of the subject matter of the invention the risk of serious damage to the socket or the spigot end and the risk of leaks occurring in the most effective Way is leaning forward.
Auf der Zeichnung ist die Erfindung an einem Ausführungsbeispiel weiter erläutert.In the drawing, the invention is further explained using an exemplary embodiment.
Es zeigen Abb. 1 den Längenschnitt, Abb. 2 den Querschnitt nach Linie I-1 der Abb. 1.Fig. 1 shows the longitudinal section, Fig. 2 shows the cross section along line I-1 of Fig. 1.
Das Spitzende 4 des Rohres wird durch die im Muffengrund hinter dem Dichtungsraum angeordneten schmalen Rippen 2, die nach dem Muffengrund zu kegelig verlaufen, zentriert, so daß die Dichtung 1 bequem eingesetzt und mittels der Gewindestopfbüchse 5 festgezogen werden kann. Die Rippen 2 werden in jeweils passender Anzahl entsprechend dem Durchmesser der Röhren angeordnet.The spigot end 4 of the pipe is in the socket base behind the sealing space arranged narrow ribs 2, which are too tapered after the socket base, centered so that the seal 1 is convenient can be used and tightened by means of the threaded gland 5. The ribs 2 are each in a suitable number arranged according to the diameter of the tubes.
