Description
Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruchs 1, wie sie aus Fig. 4 der DE 36 16 227 A1 be kannt ist. Dort sind die Ringe auf das Meßrohr aufgeschrumpft, wodurch das Meßrohr unter Vorspannung steht und bei Betrieb brechen kann. Um diese Vorrichtung zusammenbauen zu können, muß ferner der Innendurchmesser des Trägerrohrs größer als der Außendurchmesser der Ringe sein. Wegen des unvermeidlichen Zwischenraums zwischen Trägerrohr und Meßrohr ist die Konstruk tionsfreiheit von Meßrohr und Trägerrohr eingeschränkt. Nach einer weiteren Ausführung gemäß Fig. 6 dieser Schrift ist der Ring ohne Vermittlung eines elastischen Dichtungsrings in einem axial offenen Ringflansch des Meßrohrs aufgenommen.The invention relates to a device according to the preamble of claim 1, as it is known from FIG. 4 of DE 36 16 227 A1. There the rings are shrunk onto the measuring tube, which means that the measuring tube is under tension and can break during operation. In order to be able to assemble this device, the inner diameter of the carrier tube must also be larger than the outer diameter of the rings. Because of the unavoidable space between the support tube and the measuring tube, the design freedom of the measuring tube and the support tube is restricted. According to a further embodiment according to FIG. 6 of this document, the ring is accommodated in an axially open ring flange of the measuring tube without the provision of an elastic sealing ring.
Aufgabe der Erfindung ist es, die Bruchsicherheit des Meßrohrs ohne Einschränkung der Konstruktionsfreiheit der Vorrichtung zu erhöhen.The object of the invention is the break resistance of the measuring tube without restricting the design freedom of the device increase.
Die Lösung dieser Aufgabe ist in Anspruch 1 angegeben.The solution to this problem is specified in claim 1.
Zur Lösung der Aufgabe haben sich besonders die Ausführungen gemäß Anspruch 2 und 3 bewährt.In particular, the explanations have to solve the task proven according to claim 2 and 3.
Die Erfindung wird im folgenden an einem Ausführungsbeispiel unter hinweis auf die beigefügte Zeichnung erläutert.The invention is based on an embodiment explained with reference to the accompanying drawing.
In der Zeichnung ist ein Meßrohr in einem Trägerrohr mit den zugehörigen, zur Abstützung dienenden Ringen im Achsschnitt dargestellt.In the drawing, a measuring tube is in a carrier tube with the associated support rings in the axial section shown.
Ein Meßrohr 2 aus Keramik, Glas, Metall oder Kunststoff ist in ein Trägerrohr 4 aus Metall eingesetzt. Zwischen den Enden 6, 8 des Meßrohrs 2 und den Enden 10, 12 des Trä gerrohrs 4 befinden sich Ringe 14, 16 aus Keramik, Glas, Me tall oder Kunststoff, die an dem Meßrohr 2 und dem Träger rohr 4 durch elastische Dichtungsringe 18, 20, 22, 24 abgestützt sind. A measuring tube 2 made of ceramic, glass, metal or plastic is inserted into a carrier tube 4 made of metal. Between the ends 6 , 8 of the measuring tube 2 and the ends 10 , 12 of the carrier tube 4 there are rings 14 , 16 made of ceramic, glass, metal or plastic, which are on the measuring tube 2 and the carrier tube 4 by elastic sealing rings 18 , 20 , 22 , 24 are supported.
Zur Aufnahme der Ringe 18, 20, 22, 24 befinden sich in den Enden 6, 8 des Meßrohrs 2 und den Enden 10, 12 des Trägerrohrs 4 axial offene Ringausnehmungen 26, 28, 30, 32.To receive the rings 18 , 20 , 22 , 24 there are axially open ring recesses 26 , 28 , 30 , 32 in the ends 6 , 8 of the measuring tube 2 and the ends 10 , 12 of the carrier tube 4 .
Die Dichtungsringe 18, 20, 22, 24 liegen in axial inneren Ringschultern 34, 36, 38, 40, die in den radial inneren und radial äußeren, axial nach innen weisenden Kantenbe reichen der Ringe 14, 16 eingeformt sind.The sealing rings 18 , 20 , 22 , 24 are located in the axially inner annular shoulders 34 , 36 , 38 , 40 , which are formed in the radially inner and radially outer, axially inwardly facing edges of the rings 14 , 16 .
