Description
O O
Die Erfindung betrifft eine dauerhafte und dichte Verbindung von Rohren untereinander, bzw. von Rohren und Fittingen, aus verschiedenen Materialien, welche mittels radialer Rundumverpressung durch ein zangenförmiges Werkzeug, erreicht wird. Rohrverbindungen dieser Art sind in vielfältiger Form in der· Sanitäi— und Heizungbranche, bekannt. Wie z.B. Offenlegungsschrift DE 3423283 A 1, G 94 06 748.1 oder DE A 1 PN 4211959 zeigt.The invention relates to a permanent and tight connection between pipes, or between pipes and fittings, made of different materials, which is achieved by means of radial all-round pressing using a pliers-shaped tool. Pipe connections of this type are known in many different forms in the sanitary and heating industry. As shown, for example, in the published patent application DE 3423283 A 1, G 94 06 748.1 or DE A 1 PN 4211959.
Die Verbindung, die z.b. wasserdicht sein muß, wird dadurch erreicht, daß ein Rohr z.B. auf einen mit O-Ringen bestückten Fitting geschoben wird und mit einem zangenförmigen Werkzeug am äußeren Umfang, verquetscht wird.The connection, which must be watertight, is achieved by pushing a pipe onto a fitting equipped with O-rings and squeezing it on the outer circumference with a pliers-shaped tool.
In den meisten Fällen werden 1 oder mehrere O-Ringe verwendet, die auf dem Trägerrohr oder Fitting in einer speziellen Nut, eingebettet sind. Die Herstellung und die nachfolgende Bestückung der Teile mit dem 0—Ring, ist nicht nur kompliziert, sondern auch teuer, zumal die O-Ringe leicht verletzbar sind, was zu undichten Verbindungen führt.In most cases, one or more O-rings are used, which are embedded in a special groove on the carrier pipe or fitting. The production and subsequent fitting of the parts with the O-ring is not only complicated, but also expensive, especially since the O-rings are easily damaged, which leads to leaky connections.
Eine weitere Lösung besteht darin, ösii ein weiches Kunststoffrohr verwendet wird, wo vor der Montage zusätzlich eine Metallhülse übergestülpt wird, die nach der Montage mittels Zange verquetscht wird.Another solution is to use a soft plastic tube, where a metal sleeve is additionally put over it before assembly, which is then squeezed using pliers after assembly.
Alle diese Lösungen haben den Nachteil, daß Sie aus mindestens 3 Teilen bestehen, die verpresst werden müssen. Außerdem sind Montagefehler durch den Anwender möglich, wie z.B. fehlendes entgraten oder säubern der Rohrenden, Das führt zur Zerstörung der 0—Ringdichtung, sodaß große Schäden durch auslaufendes Wasser in Bauten aller Art, entstehen können.All of these solutions have the disadvantage that they consist of at least three parts that have to be pressed together. In addition, assembly errors by the user are possible, such as not deburring or cleaning the pipe ends. This leads to the destruction of the 0-ring seal, so that major damage can be caused by water leaking out in all types of buildings.
Ein weiterer Nachteil ist, daß die bestehenden Systeme untereinander nicht kompatibel sind.Another disadvantage is that the existing systems are not compatible with each other.
Der Erfindung liegt daher die Aufgabe zugrunde, eine sichere und einfache Rohrverbindung zu schaffen, die zuverlässig dicht, schnell montierbar und preisgünstig ist.The invention is therefore based on the object of creating a safe and simple pipe connection that is reliably tight, quick to install and inexpensive.
-3--3-
Der Erfindung liegt daher die Aufgabe zugrunde, eine sichere, leicht zuverarbeitende, dichte und kostengünstige Rohrverbindung zu schaffen, die zuverlässig mit nur 2 Teilen zu verpressen ist.The invention is therefore based on the object of creating a safe, easy-to-process, leak-proof and cost-effective pipe connection that can be reliably pressed together using only 2 parts.
Diese Aufgabe wird bei dieser Rohrverbindung durch das Merkmal des kennzeichnenden Teils des Anspruchs 1, dadurch gelöst,This object is achieved in this pipe connection by the feature of the characterizing part of claim 1, in that
daß die erfindungsgemäße Rohrverbindung nur noch aus 2 zu verpressenden Teilen besteht, da der Fitting oder Rohrstutzen, wie unter Anspruch 1 geschildert, mit Gummi oder Kunststoff unlösbar beschichtet ist.that the pipe connection according to the invention only consists of 2 parts to be pressed together, since the fitting or pipe socket, as described in claim 1, is inseparably coated with rubber or plastic.
Beispielsweise läßt sich aus recycelten Autoreifen ein Gummigranulat herstellen, welches sich später auf den Fitting oder Rohrstutzen aufvulkanisieren läßt.For example, recycled car tires can be used to make rubber granulate, which can later be vulcanized onto the fitting or pipe socket.
Weiterhin entsteht durch die Beschichtung eine Isolationsschicht und zudem, nach Einbau in Trinkwassersysteme, zusätzlich eine Geräuschminderung. Furthermore, the coating creates an insulating layer and, after installation in drinking water systems, also reduces noise.
Durch Überstülpen des Oberrohres auf den z.B. gummibeschichteten Fitting mit der nachfolgenden Rohrverpressung mittels Presszange entsteht, eine unlösbare, sichere und dichte Verbindung.By slipping the upper tube over the rubber-coated fitting and then pressing the pipe using a pressing tool, an inseparable, secure and tight connection is created.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche 2-5.Advantageous embodiments of the invention are the subject of subclaims 2-5.
Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand d&r· Zeichnung näher dargestellt. An embodiment of the invention is illustrated in more detail below with reference to the drawing .
Fig.1 Längsschnitt eines mit Gummi aufvulkanisierten
Fittings.
Fig.2 aufgeweitetes Rohr zum Überstülpen auf den
Fitting unter Fig. 2.Fig.1 Longitudinal section of a fitting vulcanized with rubber.
Fig.2 expanded pipe to be slipped over the fitting under Fig. 2.
Fig.3 Längsschnitt zeigt eine Kunststoff— oder Gummibeschichtung im Inneren des Rohres. Fig.4 Detailschnitt mit eingeführten Rohrabschnitt. Fig.5 Schnitt A-B mit trichterförmig aufgeweiteten Enden.Fig.3 Longitudinal section showing a plastic or rubber coating inside the pipe. Fig.4 Detailed section with inserted pipe section. Fig.5 Section A-B with funnel-shaped widened ends.
Fig.6 und 7 Schnitt A-B verpresstes Rohr mit Fitting.Fig.6 and 7 Section A-B pressed pipe with fitting.
In Fig. 1 ist ein voll mit Gummi vulkanisierter Fitting erkennbar. Der in Fig. 2 gezeigte Rohrabschnitt ist so aufgeweitet, daß er auf den in Fig. 2 dargestellten Fitting mühelos aufgeschoben werden kann. Durch das Aufweiten des Rohres wird außerdem der sehr gefährliche Grat, bedingt durch das Abschneiden eines Rohre, automatisch entfernt.In Fig. 1 you can see a fitting that is fully vulcanized with rubber. The pipe section shown in Fig. 2 is expanded so that it can be easily pushed onto the fitting shown in Fig. 2. By expanding the pipe, the very dangerous burr caused by cutting off a pipe is automatically removed.

Die Fig. 3 und 4. stellt einen teleskopartigen Rohrabschnitt, welcher innen mit Gummi oder kornpressiblen Kunststoff beschichtet ist, dar, der dazu dient, einen Längenausgleich zu schaffen. Außerdem können zu kurze Rohre bzw. aneinander gesteckt und miteinander verpresst werden.Figures 3 and 4 show a telescopic pipe section, which is coated on the inside with rubber or compressible plastic, which serves to compensate for length differences. In addition, pipes that are too short can be pushed together and pressed together.
Fig.5 zeigt als Beispiel einen Fitting mit der trichterförmigen Aufweitung, welche als Sicherung nach dem Vorpressen der gefügten Teile, gegen Zug gedacht ist.Fig.5 shows as an example a fitting with the funnel-shaped expansion, which is intended to secure the joined parts against tension after pre-pressing.
In der Fig.6 und 7 ist als Beispiel eine komplett verpreßte Rohrverbindung dargestellt, die den Anspruch 1 begründet.In Fig. 6 and 7, a completely pressed pipe connection is shown as an example, which justifies claim 1.
