Description

entsprechend ausgebildeten Werkzeuges konisch aufgeweitet wird. Das konisch aufgeweitete Rohrende wird sodann auf die Muffe aufgeschoben und durch eine Überwurfmutter, die schon vorher auf das Rohr aufgebracht wurde, festgelegt.appropriately trained tool is widened conically. That The flared end of the pipe is then pushed onto the socket and through a Union nut, which was previously applied to the pipe, set.

Die bisher üblichen und bekannten derartigen Muffenverbindungen sahen kegelige Enden vor, auf welche die aufgeweiteten Rohrenden aufgeschoben wurden. The hitherto customary and known such socket connections saw conical ends on which the expanded pipe ends were pushed.

Hier kam es nun häufig vor, dass während des Zuziehens der Überwurfmutter das Rohrende mehr oder weniger von der Muffe abrutschte, sodass die Verbindung nicht einwandfrei hergestellt war. Vor allem kann dies nicht kontrolliert werden, da die Überwurfmutter ja die Verbindungsstelle abdeckt. Um diesem Übelstand abzuhelfen, wurde der weiterhin bekannte Vorschlag gemacht, das kegelig ausgebildete Ende der Muffe zu hinterschneiden, sodass also ein Wulst entsteht, über den das Rohrende geschoben werden kann. Bei der durch die Erwärmung gegebenen Plastizität des Rohrendes reicht aber auch dieser eine Wulst zur sicheren Festlegung des Rohrendes auf dem Muffenkonus, so lange, bis die Überwurfmutter festgedreht ist, nicht aus.Here it often happened that while the union nut was being tightened the end of the pipe slipped more or less off the socket, so that the connection did not was flawlessly manufactured. Above all, this cannot be controlled because the Union nut covers the connection point. To remedy this evil, the well-known proposal was made, the tapered end of the To undercut the socket, so that a bead is created over which the pipe end can be pushed. With the plasticity of the pipe end due to the heating But even this one bead is enough to securely fix the pipe end on the Socket cone until the union nut is tightened.

Neuerungsgemäss wird vorgeschlagen, dieser Unzuträglichkeit dadurch abzuhelfen, dass an der Muffe mehrere Hinterschneidungen mit sägezahnartigem Querschnitt vorgesehen sind. According to the innovation, it is proposed that this inconvenience thereby to remedy that on the socket several undercuts with a sawtooth-like cross-section are provided.

Durch diese Ausbildung des muffenende wird eine einwandfreie Festlegung des Rohrendes auf der Muffe gewährleistet so lange, bis die Überwurfmutter wange- zogen ist. Das Rohrende kann sich während des Anziehens der Überwurfmutter nicht mehr mehr oder weniger wieder von dem Muffenkonus lösen. Albert Theysohn, Heltersberg/Pfalz "Muffenverbindung für Kunststoffrohre" Vorzugsweise in der Wasserversorgung, aber auch auf den verschiedensten anderen Gebieten setzen sich gegenüber den bisher gebräuchlichen Metallrohren in immer grösserem Umfang Rohre aus Kunststoff durch. Diese weisen eine Reihe entscheidender Vorteile gegenüber Metallrohren auf. So sind sie z. B. nahezu frostunempfindlich, sie sind unempfindlich gegen aggressive Bestandteile des Wassers oder sonstiger, die Rohrleitungen durchfliessenden Flüssigkeiten, sie können in grossen Längen verlegt werden. Falls nicht aus irgendeinem Grund eine lösbare Verbindung vorgesehen sein muss, können diese Rohrlängen in einfacher Weise miteinander versohweisst werden.This design of the socket end ensures that the pipe end is properly fixed on the socket guaranteed until the union nut is cheek- is pulled. The pipe end can no longer detach itself more or less from the socket cone while the union nut is being tightened. Albert Theysohn, Heltersberg / Palatinate "Socket connection for plastic pipes" Preferably in the water supply, but also in a wide variety of other areas, plastic pipes are increasingly gaining ground over the metal pipes that have been used up to now. These have a number of decisive advantages over metal pipes. So they are z. B. almost insensitive to frost, they are insensitive to aggressive components of the water or other liquids flowing through the pipelines, they can be laid in great lengths. If a detachable connection does not have to be provided for some reason, these pipe lengths can be welded to one another in a simple manner.

Bei lösbaren Verbindungen sieht man u. a. sogenannte Muffenverbindungen vor. Dabei wird so verfahren, dass das Rohrende, das in die Muffenverbindung eingebracht werden soll, angewärmt und mittels eines Weitere Merkmale der Neuerung und Einzelheiten der durch dieselbe erzielten Vorteile ergeben sich aus der nachstehenden Beschreibung zweier in der beigefügten Zeichnung dargestellten beispielsweisen Ausführungsformen. Fig. 1 zeigt die Normalausführung, in Fig. 2 ist eine etwas variierte Ausführung mit besonderem Pressring dargestellt. In the case of detachable connections, one can see inter alia. so-called socket connections before. The procedure is such that the pipe end is inserted into the socket connection is to be warmed up and using a Other features of the innovation and details of the advantages achieved thereby are set out below Description of two exemplary embodiments shown in the accompanying drawing. Fig. 1 shows the normal version, in Fig. 2 is a somewhat varied version shown with a special press ring.

Ein Kunststoffrohr 1 soll auf eine Verbindungsmuffe aufgebracht werden. Zu diesem Zweck wird in üblicher Weise das Ende 2 des Kunststoffrohres erwärmt und mittels eines geeigneten Werkzeuges konisch aufgeweitet. Dieses erwärmte und aufgeweitete Rohrende 2 wird auf die Muffe 3 aufgeschoben und mittels einer Überwurfmutter 4 festgelegt. A plastic pipe 1 is to be placed on a connecting sleeve. For this purpose, the end 2 of the plastic pipe is heated and in the usual way widened conically using a suitable tool. This warmed and expanded The pipe end 2 is pushed onto the socket 3 and secured by means of a union nut 4 set.

Die bisher üblichen und bekannten Muffen sahen nun lediglich einen konischen Endbereich 5 mit bestenfalls einer einzigen Hinterschneidung vor, sodass ein Wulst 6 gebildet wurde. Ein solches Ende, gleichgültig ob mit oder ohne Wulst 6, konnte das aufgeweitete Rohrende 2 nicht sicher bis zur endgültigen Festlegung durch die Überwurfmutter 4 haltern, vielmehr rutschte das Rohrende in unkontrollierbarer Weise während des Aufdrehen der Überwurfmutter 4 mehr oder weniger weit vom Muffenende 5 herunter, sodass die endgültige Verbindung nicht einwandfrei war. The previously common and well-known sleeves now only saw one conical end area 5 with at best a single undercut, so that a bead 6 was formed. Such an end, whether with or without a bead 6, the expanded pipe end 2 could not be sure of until it was finally fixed Hold by the union nut 4, rather the pipe end slipped in uncontrollable Way while unscrewing the union nut 4 more or less far from the socket end 5 so that the final connection was not perfect.

Neuerungsgemäss sind nun am Muffenende mehrere Hinterschneidungen 7 mit sägezahnartigem Querschnitt vorgesehen. Durch diese Ausbildung der Muffe wird das Rohrende 2 in jedem Fall sicher in seiner aufgeschobenen Lage festgehalten bis die endgültige Festlegung durch die Überwurfmutter 4 erfolgt. According to the innovation, there are now several undercuts at the socket end 7 provided with a sawtooth-like cross-section. Through this training the sleeve is the The end of the pipe 2 is always secure in its pushed-on position held until the final determination by the union nut 4 takes place.

Die Fig. 2 unterscheidet sich von der Fig. 1 lediglich dadurch, dass nicht die Überwurfmutter 4 einen konisch nach innen gezogenen Kandbereich aufweist, sondern mit einem besonders vorgesehenen Anpressring 8 ausgestattet ist, der seinerseits das Anpressen des Rohres 1 an die konische Oberfläche des Muffenendes 5 übernimmt. FIG. 2 differs from FIG. 1 only in that the union nut 4 does not have a conically inwardly drawn edge area, but is equipped with a specially provided pressure ring 8, which in turn the pressing of the pipe 1 against the conical surface of the socket end 5 takes over.
