MANUFACTURE METAILÜRGIQUE DE IA JOIiCHERE, Paris, Frankreich Biegsame Kupplung für RohrleitungenMANUFACTURE METAILÜRGIQUE DE IA JOIiCHERE, Paris, France Flexible coupling for pipelines

Die Erfindung bezieht sich auf eine biegsame Kupplung, die es erlaubt, zwei starre oder biegsame Rohrleitungen zu verbinden. The invention relates to a flexible coupling which allows two rigid or flexible pipelines to be connected.

Diese Vorrichtung spielt eine ähnliche Rolle wie die bekannten Gelenkverbindungen.This device plays a role similar to that of the known articulated joints.

Die biegsame Kupplung für Rohrleitungen ist dadurch gekennzeichnet, daß sie zwei Verbindungsstücke an den Rohrleitungen und zwischen diesen beiden Verbindungsstücken koaxial angeordnet (in Ruhelage) eine innere "biegsame Hülle und eine äußere gefaltete "Membran", die an den beiden Verbindungsstücken befestigt sind, umfaßt.The flexible coupling for pipelines is characterized by that they have two connectors on the pipelines and between these two connecting pieces coaxially arranged (in the rest position) an inner "flexible sheath and an outer folded one "Membrane" attached to the two connectors.

Ferner kann die innere Hülle aus einem flexiblen dichten oder undichten Schlauch bestehen. In Ruhelage kann sie mit den ·Furthermore, the inner sheath can consist of a flexible, tight or leaky hose. In a resting position, it can be used with the

Weitere Einzelheiten, Vorteile und Merkmale der Erfindung ergeben sich aus der folgenden Beschreibung. Auf der Zeichnung ist die Erfindung beispielsweise veranschaulicht, und zwar zeigen Fig. 1 und 2 jeweils eine Seitenanseicht von zwei verschiedenen Ausführungsformen der Vorrichtung, teilweise im Schnitt»Further details, advantages and features of the invention result from the following description. In the drawing, the invention is illustrated by way of example, namely show 1 and 2 each a side view of two different embodiments of the device, partly in section »

Die Verbindung gemäß Fig. 1 setzt sich aus zwei in diesem Fall gleichen Kupplungsstücken 1 und 2 zusammen und weist Befestigungsmittel (Innengewinde, Schweißverbindungen od.dgl., nicht dargestellt), an den zu verbindenden Rohrleitungen 3 und 4 auf. Der biegsame Teil der Kupplung umfaßt eine biegsame innere Hülle,5, die beispielsweise aus einem Stück eines flexiblen dichten oder undichten Schlauchs von bekannter Art, je nach Bedarf besteht,, Sie umfaßt ferner ein "Membran"-Element 6 oder einen elastischen Faltenbalg, doh. einen gefalteten Schlauch, der große Möglichkeiten der elastischen Verformung parallel zur Achse x-x und schräg zu ihr aufweist.The connection according to FIG. 1 consists of two coupling pieces 1 and 2, which in this case are identical, and does not have fastening means (internal thread, welded connections or the like shown) on the pipes 3 and 4 to be connected. The flexible part of the coupling comprises a flexible inner shell, 5, which, for example, consists of a piece of flexible, tight or leaky hose of known type, as required, includes you also a "membrane" element 6 or an elastic bellows, doh. a folded tube that has great possibilities of elastic deformation parallel to the x-x axis and oblique to it having.

Im Fall der Fig» vl laufen die Wellen der Membran 6 rund um die Achse x-x.In the case of Figure "v l is the wave of the diaphragm 6 running around the axis xx.

Im Fall einer undichten inneren Hülle 5 stellt die Membran die Dichtheit sichero Im Fall einer dichten Hülle 5 hält die Membran 6 ' keinen Druck aus und es ist bekannt, daß im Fall eines zu starken Drucks die Membranen bleibend Verformungen erleiden können. DagegenIn the case of a leaky inner shell 5, the membrane ensures the tightness o In the case of a tight shell 5, the membrane 6 'does not withstand any pressure and it is known that the membranes can suffer permanent deformations in the event of excessive pressure. Against it

nimmt die Membran an der Verformung und am Widerstand gegen die Beanspruchungen teil, die sich durch die möglichen Verschiebungen der Enden der verbundenen Rohrleitungen 3 und 4 (Ausdehnung od.dgl.) ergeben.the membrane counteracts deformation and resistance the stresses caused by the possible displacements the ends of the connected pipes 3 and 4 (expansion or the like.) Result.

In beiden Fällen können die inneren Teile der fellen der Membran im Laufe der Verformung der Kupplung bis zur Berührung mit der biegsamen Hülle 5 kommen und diese trägt dann zur Widerstandsfestigkeit der Membran teil, indem sie beispielsweise die oben erwähnten bleibenden Verformungen verhindert. In both cases, the inner parts of the skin of the membrane can in the course of the deformation of the coupling up to the point of contact come with the flexible sheath 5 and this then contributes to the resistance of the membrane, for example by preventing the permanent deformations mentioned above.

Die biegsame Hülle 5 kann in Ruhelage sich mit den Wellen der Membran 6 berühren. Die beiden Stücke werden dann eins durch das andere verstärkt, entweder wenn die verbundenen Rohrleitungen unter Druck ,,gesetzt werden oder bei Verschieben der Enden der Rohrleitungen,The flexible sheath 5 can be with the waves in the rest position touch the membrane 6. The two pieces are then reinforced one by the other, either when the connected piping under pressure, or when moving the ends of the Pipelines,

Die Ausführungsform gemäß Fig. 2 unterscheidet sich von der μ der Fig«, 1 nur durch Vorhandensein von spiralförmigen Wellen der Membran 7 anstelle der umlaufenden Wellen um die Achse x-x.The embodiment according to FIG. 2 differs from the μ of FIG. 1 only in the presence of spiral waves of the membrane 7 instead of the rotating waves about the axis xx.

Zusammenfassend ist zu sagen, daß die biegsame Kupplung für Rohrleitungen zwei Kupplungsstücke an den Rohrleitungen und koaxial (in Ruhelage) zwischen den beiden Kupplungsstücken angeordnet eine innere biegsame, Hülle und eine äußere gefaltete "Membran", die an den beiden Kupplungen befestigt sind, umfaßt.In summary, the flexible coupling for pipelines has two coupling pieces on the pipelines and coaxially (in the rest position) between the two coupling pieces arranged comprises an inner flexible sleeve and an outer pleated "membrane" attached to the two couplings.

Die innere Hülle kann ein flexibler dichter oder undichter Schlauch sein. In Ruhelage kann sie sich mit den Falten der Membran berühren oder nicht berühren.The inner sheath can be a flexible, tight or leaky tube. In a resting position, she can deal with the Touching or not touching the folds of the membrane.
