Description

Anordnung zum Verbinden eines ersten mit einem zweiten RohrArrangement for connecting a first to a second tube
Die Erfindung betrifft eine Anordnung zum Verbinden eines ersten Rohrs mit einem zweiten Rohr, welche von einem Heißgas durchströmt werden, sowie ein Montageverfahren hierfür.The invention relates to an arrangement for connecting a first tube to a second tube through which a hot gas flows and to an assembly method therefor.
Zum Verbinden von zwei Rohren ist dem Fachmann die Steckrohrverbindung bekannt. Bei dieser wird ein erstes Rohr, welches einen größeren Innendurchmesser aufweist, über ein zweites Rohr geschoben. Auf Grund der Selbsthemmung ist eine weitere Befestigung der Rohre gegeneinander nicht notwendig. Damit bei dieser Anordnung die Selbsthemmung auftritt, darf das Verhältnis von Überlappung zu Rohr-Durchmesser nicht unter eins sein. Hieraus resultiert eine entsprechende Baulänge. Bei beengten Platzverhältnissen ist dies nachteilig.The plug-in pipe connection is known to the person skilled in the art for connecting two pipes. In this case, a first tube, which has a larger inner diameter, is pushed over a second tube. Due to the self-locking, it is not necessary to fix the pipes to each other. In order for self-locking to occur with this arrangement, the ratio of overlap to pipe diameter must not be less than one. This results in a corresponding overall length. This is disadvantageous in confined spaces.
Aufgabe der Erfindung ist es, eine Anordnung bereitzustellen, welche eine kürzere Baulänge aufweist und einfach zu montieren ist.The object of the invention is to provide an arrangement which has a shorter overall length and is easy to assemble.
Die Aufgabe wird durch die Merkmale von Anspruch 1 und Anspruch 8 gelöst. Die vorteilhaften Ausgestaltungen sind in den Unteransprüchen dargestellt.The object is solved by the features of claim 1 and claim 8. The advantageous embodiments are shown in the subclaims.
Die Anordnung umfasst ein Ausgleichselement zur Aufnahme eines lateralen Versatzes zwischen dem ersten und zweiten Rohr. Bei dem Ausgleichselement handelt es sich um eine mehrstufige, gebaute Ausführung. Diese besteht aus einem ersten und zweiten Ring sowie einem Dichtring. Zur Verbindung des ersten mit dem zweiten Rohr werden in einem ersten Schritt der Dichtring und der erste Ring auf das zweite Rohr aufgeschoben. Danach wird mittels des zweiten Rings der Dichtring gegenüber dem ersten Ring axial fixiert und anschließend das Ausgleichselement über ein V-Band mit dem ersten Rohr verbunden.The arrangement comprises a compensating element for receiving a lateral offset between the first and second tubes. The compensating element is a multi-stage, built version. This consists of a first and second ring and a sealing ring. To connect the first to the second tube, the sealing ring and the first ring are pushed onto the second tube in a first step. Then the sealing ring is axially fixed with respect to the first ring by means of the second ring and then the compensating element is connected to the first tube via a V-band.
In einer Ausführung der Erfindung ist vorgesehen, dass das Ausgleichselement eine erste und zweite Ringhälfte umfasst. Das zweite Rohr besitzt ein flanschartiges Endstück, welches vom Ausgleichselement umfasst wird. Durch das Ausgleichselement werden laterale und axiale Versätze, welche durch Wärmedehnungen und Toleranzen hervorgerufen werden, zwischen den beiden Rohren ausgeglichen. Hierdurch werden Wärmespannungen zwischen den beiden Rohren verhindert. Da eine absolute Dichtheit ebenso wie bei Steckrohren nicht erforderlich ist, kann der Dichtring einstückig ausgeführt werden, das heißt, er muss nicht geschlitzt sein. Durch die mehrteilige, gebaute Ausführung des Ausgleichselements lässt sich dieses einfach montieren. Gegenüber einer Steckrohrverbindung baut das Ausgleichselement kürzer.In one embodiment of the invention it is provided that the compensating element comprises a first and second ring half. The second tube has a flange-like end piece, which is surrounded by the compensating element. The compensating element compensates for lateral and axial offsets, which are caused by thermal expansion and tolerances, between the two pipes. This prevents thermal stresses between the two pipes. Since absolute tightness is not required, just as with plug-in tubes, the sealing ring can be made in one piece, which means that it does not have to be slotted. The multi-part, built version of the compensating element makes it easy to install. Compared to a plug-in pipe connection, the compensating element is shorter.

Dies ist in Figur 2 mit den Pfeilen A dargestellt. In radialer Richtung kann sich das zweite Rohr 3 gegenüber dem ersten Rohr 2 bewegen bzw. vice versa, da der Dichtring 7 innerhalb der U-förmigen Innenkontur des ersten Rings 5 sich bewegen kann. Dies ist in Figur 2 mit den Pfeilen B dargestellt.The second tube 3 can move in the axial direction relative to the first tube 2 or vice versa, since the sealing ring 7 is displaceable on the second tube 3. This is shown in Figure 2 with the arrows A. The second tube 3 can move in the radial direction relative to the first tube 2 or vice versa, since the sealing ring 7 can move within the U-shaped inner contour of the first ring 5.
