Description

Rohrfittingverbind ng Pipe fitting connection
Die Erfindung bezieht sich auf eine Rohrfittingver- bindung insbesondere für Sanitär- und Heizungsanlagen, sowie Radiatoren u.dgl., wobei das Fitting in ein Rohrprofil, beispielsweise eines Radiatorsammelrohres, abdichtend eingesetzt ist, welches aus kaltfließbarem Material, beispielsweise Aluminium, besteht, und das Fitting mit mindestens einem Dichtring versehen ist, der am Innenmantel des Rohrprofiles dichtend anliegt, sowie an mindestens zwei einander gegenüberliegendenThe invention relates to a pipe fitting connection, in particular for sanitary and heating systems, and radiators and the like.

Charakteristik des bekannten Standes der TechnikCharacteristic of the known prior art
Ein besonderes Anwendungsgebiet für die erfindungsgemäße Fittingverbindung sind, wie bereits eingangs erwähnt, Heizungsradiatoren. In vielen Fällen werden Heizungs¬ radiatoren von einem Gliederstrang aus Leichtmetall¬ profilen gebildet, die aus einer Reihe von Gliedern mit Steigrohren für das Wärmeaustauschmedium und im wesent¬ lichen H-förmigen Austauschstegen und an den Enden ange¬ ordneten Sammelrohren besteht. Die Sammelrohre stellen das Rohrprofil der Fittingverbindung dar.As already mentioned at the beginning, heating radiators are a particular area of application for the fitting connection according to the invention. In many cases, heating radiators are formed from a link strand made of light metal profiles, which consists of a series of links with riser pipes for the heat exchange medium and essentially H-shaped exchange webs and collecting pipes arranged at the ends. The header pipes represent the pipe profile of the fitting connection.
Derartige Heizkörper werden meist aus Leichtmetallstrang- preßprofilen hergestellt. Nach einem Vorschlag des gleichen Anmelders, wird hiezu der Gliedersträng imSuch radiators are usually made from extruded light metal profiles. According to a proposal by the same applicant, the link strand in the

Aufgabe und Wesen der ErfindungObject and nature of the invention
Aufgabe der Erfindung ist es in erster Linie eine Fittingverbindung zu schaffen, die besser abdichtet, als die herkömmlichen Verbindungen, bei denen sowohl das Rohrstück als auch das Fitting mit einem Gewinde versehen sind, wobei das Fitting in das Rohrstück eingeschraubt ist und zur Abdichtung beispielsweise Hanf verwendet wird.The object of the invention is primarily to provide a fitting connection which seals better than the conventional connections in which both the pipe section and the fitting are provided with a thread, the fitting being screwed into the pipe section and for sealing, for example, hemp is used.
Eine weitere Aufgabe der Erfindung ist es, eine Fitting-> Verbindung zu schaffen, die schnell herzustellen ist, insbesondere soll auf dem abzulängenden Teil, der na¬ türlich das Rohrstück ist, kein Gewinde eingeschraubt werden müssen.Another object of the invention is to provide a fitting connection that can be established quickly, in particular that no thread has to be screwed onto the part to be cut to length, which is of course the pipe section.
Selbstverständlich ist* es für die erfindungsgemäßeOf course it is * for the invention
Fittingverbindung ohne Bedeutung, ob es sich dabei um einen sogenannten Blindstopfen, Entlüftungstopfen oder Anschlußstopfen handelt.Fitting connection irrelevant, whether it is a so-called blind plug, vent plug or connection plug.
Insbesondere ist die erfindungsge äße Fittingverbindung zur Anwendung bei Zwillings- und Drillingsverbindem geeignet.In particular, the fitting connection according to the invention is suitable for use with twin and triple connectors.
Dies wird erfindungsge äß dadurch erreicht, daß das Fitting aus härterem Material als das Rohrprofil ist, und daß das Rohrprofil an die Profilierung verzahnend unter Verformung angepreßt ist.This is achieved according to the invention in that the fitting is made of harder material than the tubular profile, and in that the tubular profile is pressed in a toothed manner to the profile with deformation.
Abgesehen von der hohen Dichtungsgualität der erfindungs¬ gemäßen Fittingverbindung hat diese den enormen Vorteil, daß in das Rohrprofil kein Gev/inde eingeschnitten werden muß. Dies ist insbesondere bei der zuvor erwähnten on- fektionierung von Radiatoren, beispielsweise bei einem Heizungsgroßhändler, von Bedeutung, da dort im allge¬ meinen kein handwerklich geschultes Personal zur Ver¬ fügung steht, das das Gewinde schneiden könnte. Abge¬ sehen davon wird bei der erfindungsgemäßen Fittingver- bindung ein wesentlicher Zeitvorteil erzielt.Apart from the high sealing quality of the fitting connection according to the invention, this has the enormous advantage that no gev / inde has to be cut into the pipe profile. This is particularly the case with the aforementioned assembly of radiators, for example one Heating wholesaler, of importance, since there is generally no skilled personnel available to cut the thread. Apart from this, a substantial time advantage is achieved with the fitting connection according to the invention.
Das Verpressen des Profilstückes erfolgt vorzugsweise mittels einer hydraulischen Zange, kann aber auch mechanisch mit einer geeigneten Übersetzung erfolgen, mit der ein Preßdruck von beispielsweise ungefähr 500 kg erzielt werden kann.The profile piece is preferably pressed by means of hydraulic pliers, but can also be done mechanically with a suitable ratio, with which a pressing pressure of, for example, approximately 500 kg can be achieved.
Je nach Beschaffenheit des Rohrstückes können jedoch auch gegebenenfalls geringere Preßdrücke ausreichen.Depending on the nature of the pipe section, however, lower pressures may also be sufficient.
Ein vorteilhaftes Ausführungsbeispiel der Erfindung sieht vor, daß die Profilierung von das Fitting um- laufenden Stegen gebildet wird.An advantageous embodiment of the invention provides that the profiling is formed by webs surrounding the fitting.
Ein weiteres Ausführungsbeispiel ist dadurch gekenn¬ zeichnet, daß die Profilierung von einem Steg gebildet wird, der. in der Art eines Gewilideganges ausgebildet ist.Another embodiment is characterized in that the profiling is formed by a web which. is designed in the manner of a Gewilideganges.
Durch diese Ausführung ist das Fitting wiederverwendbar, d.h. es kann nach dem Verpressen aus dem Rohrstück aus¬ geschraubt werden, während bei seiner Montage es ledig¬ lich in das Rohrstück eingeschoben und dann verpreßt wird.This design makes the fitting reusable, i.e. it can be unscrewed from the pipe section after pressing, while it is only inserted into the pipe section during assembly and then pressed.
Bei einem weiteren Ausführungsbeispiel der Erfindung sind zwei Dichtringe vorgesehen, die sich beider¬ seitig der Profi'lierung befinden.In a further exemplary embodiment of the invention, two sealing rings are provided, which are located on both sides of the profiling.
Ist nur ein Dichtring vorgesehen, wird sich dieser zwischen der Stelle oder den Stellen mit der Profilierung und dem äußeren Ende des Rohrprofiles befinden.If only one sealing ring is provided, it will be located between the location or locations with the profiling and the outer end of the tubular profile.
0 -- , - -0 -, - -
Weiters ist vorteilhaft vorgesehen, daß das Fitting im Bereich der Profilierungen abgeflacht ist.It is also advantageously provided that the fitting is flattened in the area of the profiles.
Die Verpressung des Rohrprofiles erfolgt vorteilhaft punktweise.The pipe profile is advantageously pressed point by point.
Vorteilhaft ist vorgesehen, daß das Fitting aus Stahl ist und weiters, daß das Rohrprofil aus gezogenem Aluminium ist. Das Rohrprofil aus gezogenem Aluminium gewährleistet eine besonders saubere Abdichtung des O-Ringes.It is advantageously provided that the fitting is made of steel and further that the tubular profile is made of drawn aluminum. The tubular profile made of drawn aluminum ensures a particularly clean seal of the O-ring.

Der Radiator besteht im wesentlichen aus Steigrohren, die von Längsprofilen 1 und aus Sammelrohren, die von Rohrprofilen 2 gebildet werden.The radiator consists essentially of riser tubes, which are formed by longitudinal profiles 1 and manifolds, which are formed by tube profiles 2.
Die erfindungsgemäße Fittingverbindung besteht zwischen je einem Sammelrohr und einem Fitting 3.The fitting connection according to the invention exists between a header pipe and a fitting 3.
In der Fig. 1 ist eine Fittingverbindung beschrieben, bei der das Fitting 3 einen Blindstopfen darstellt. Das Fitting 3 ist an seinem Mantel über die Breite d mit einer Profilierung 4 versehen, die von Stegen 5 gebildet wird, die rund um das Fitting 3 verlaufen.In Fig. 1, a fitting connection is described in which the fitting 3 is a blind plug. The fitting 3 is provided on its jacket over the width d with a profiling 4 which is formed by webs 5 which run around the fitting 3.
Beidseits der Profilierung 4 ist das Fitting 3 mit je einer Ringnut 7 versehen, vrobei in den Ringnuten 7 Dichtringe 8 angeordnet sind.The fitting 3 is provided with an annular groove 7 on each side of the profiling 4, 7 sealing rings 8 being arranged in the annular grooves.
Zur Montage wird das Fitting 3 in das Rohrprofil 2, das vorzugsweise aus gezogenem Aluminium gebildet ist, eingeschoben, worauf mit einer nicht gezeigten Zange aus der Richtung der Pfeile das Rohxprof.il 2 an den Stellen 9 verpreßt wird, sodaß es sάch mit der Profilierun 4 an zwei einander gegenüberliegenden -Punkten des Rohr¬ profiles 2 verpreßt.For assembly, the fitting 3 is inserted into the tubular profile 2, which is preferably formed from drawn aluminum, whereupon the plugs from the direction of the arrows Rohxprof.il 2 is pressed at points 9 with a pair of pliers, not shown, so that it with the profiling 4 pressed at two opposite points of the tube profile 2.
Durch diese Ausführung ist das Fitting 3 fest im Rohr¬ profil 2 gehalten und die Dichtringe 8 garantieren eine absolut sichere Abdichtung.With this design, the fitting 3 is held firmly in the tubular profile 2 and the sealing rings 8 guarantee an absolutely secure seal.
Mit einem Fitting 3 gemäß der Fig. 4 können zwei Rohr¬ profile 2 miteinander verbunden werden. Die Montage erfolgt gemäß dem zuvor beschriebenen Ausführungsbei- spiel, selbstverständlich v/erden die Rohrprofile 2 auf beiden Seiten des Fittings 3 im Bereich der Profilie- rungen 4 verpreßt. Die Ausführung eines Fittings 3 mit nur einem Dicht¬ ring 8 (wie in der Fig. 3 gezeigt) , ist dann vorteil¬ haft, wenn die Profilierung 4 als Gewindegang ausgeführt ist und so das Fitting 3 aus dem Rohrprofil 2 heraus- geschraubt und in einem anderen Rohrprofil 2 wieder neu verpreßt werden kann. Dadurch, daß sich der Dichtring 8 zwischen der Profilierung 4 und dem äußeren Ende des Rohrprofils 2 befindet, wird er beim Herausschrauben nicht beschädigt.With a fitting 3 according to FIG. 4, two pipe profiles 2 can be connected to one another. The assembly is carried out in accordance with the exemplary embodiment described above, of course the pipe profiles 2 are pressed on both sides of the fitting 3 in the region of the profiles 4. The implementation of a fitting 3 with only one sealing ring 8 (as shown in FIG. 3) is advantageous if the profiling 4 is designed as a thread and thus the fitting 3 is screwed out of the tubular profile 2 and in another pipe profile 2 can be pressed again. Characterized in that the sealing ring 8 is between the profile 4 and the outer end of the tubular profile 2, it is not damaged when unscrewing.
Die Fig. 6 und 7 zeigen jeweils über den Umfang des Fittings 3 durchgehende Profilierungen 4.6 and 7 each show continuous profiles 4 over the circumference of the fitting 3.
