Description
Verbindung zweier Rohre oder rohrförmiger Gehäuse Die Erfindung bezieht sich auf eine Verbindung zweier Rohre oder Gehäuse mit rohrförmigen Anschlüssen, insbesondere fur metallgekapselte, druckgasisolierte Rohrleitungen und Schaltanlagen; bei der die Rohre bzw. Gehäuse mit einander überlappenden Enden aneinanderliegen. Connection of two pipes or tubular housing The invention relates relate to a connection between two pipes or housings with tubular connections, in particular for metal-enclosed, pressurized gas-insulated pipelines and switchgear; in which the tubes or housings lie against one another with overlapping ends.
Solche Verbindungen sind in der älteren Patentanmeldung P 22 35 528.8 beschrieben. Während es sich bei dieser Verbindungsform um eine lösbare Verbindung handelt, bei der die Rohre mit gleichbleibendem Durchmesser an den Verbindungsstellen aneinanderliegen, geht die Erfindung von der Aufgabe aus, bei ebenfalls gleichbleibendem Durchmesser an den Verbindungsstellen eine nicht mehr ohne weiteres lösbare Verbindung herzustellen.Such compounds are in the earlier patent application P 22 35 528.8 described. While this form of connection is a detachable connection where the pipes have a constant diameter at the connection points lie against each other, the invention is based on the task, with also constant Diameter at the connection points a no longer easily detachable connection to manufacture.
Zu diesem Zweck sieht die Erfindung vor, daß die einander überlappenden Enden mit breitflächigen Aussparungen versehen sind und nach Erhitzen des einen Endes und/oder Abkühlen des anderen Endes bis zum Einrasten an den Aussparungen übereinander geschoben sind.For this purpose, the invention provides that the overlapping Ends are provided with wide recesses and after heating the one End and / or cooling of the other end until it clicks into place on the recesses are pushed over each other.
Das Erhi-tzen bzw. Abkühlen der Rohrenden soll dabei bis auf solche Temperaturen geschehen, daß elastische Abdichtungsmittel an den Stoßstellen der Rohrenden nicht in ihrer Eigenschaft beeintrcjchtigt werden. Man erhält durch die Erfindung den Vorteil, daß die Montagearbeit im Vergleich zu verschweißten Rohrverbindungen sehr vereinfacht und damit auch verbilligt wird, abgesehen davon, daß es bei mehreren Rohrleitungen in einer Baugrube häufig nicht möglich ist, solche Verschweißungen aus Platzmangel vorzunehmen.The heating or cooling of the pipe ends should be limited to such Temperatures happen that elastic sealant at the joints of the The properties of the pipe ends are not impaired. One obtains through the Invention has the advantage that the assembly work compared to welded pipe connections is very simplified and thus also cheaper, apart from the fact that there are several Pipelines in an excavation pit often do not allow such welds due to lack of space.
Die einander überlappenden Enden können zusätzlich noch verklebt sein und auch konisch mit einem Steigungswinkel von nur einigen Grad ausgeführt sein, wodurch sich eine besonders gute Abdichtung ergibt und zugleich auch eine hohe Druckkraft an der Uberlappungsstelle, die bei nur teilweisem Verkleben der tberlappungsstelle einen guten Stromübergang ermöglicht, falls die Kapselungsrohre auch zur Stromleitung mitbenutzt werden sollen.The overlapping ends can also be glued and also be conical with an angle of inclination of only a few degrees, which results in a particularly good seal and at the same time also a high compressive force at the point of overlap, which is the case with only partial gluing of the point of overlap allows a good current transfer, if the encapsulation tubes also to the power line should also be used.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch dargestellt.An embodiment of the invention is shown schematically in the drawing shown.
Mit 1 und 2 sind zwei zu verbindende Rohrenden bezeichnet.With 1 and 2 two pipe ends to be connected are designated.
Beide haben einander überlappende Enden 3 und 4, die mit Aussparungen 5 und 6 versehen sind. An den Stoßstellen der Rohrenden sind Abdichtungsringe, z.B. 0-Ringe 7 angeordnet.Both have overlapping ends 3 and 4 with cutouts 5 and 6 are provided. Sealing rings, e.g. 0-rings 7 arranged.
Nach Erhitzen des Rohrendes 2 auf beispielsweise 1000 und zweckmäßigerweise auch nach Abkühlen des Rohrendes 1, vorteilhaft in flüssiger Luft, werden die Enden übereinander geschoben, bis sie in einer solchen Position sind, daß sie nach dem Ausgleich der Temperaturen der Rohre ineinander greifen. Es ergibt sich dann ein fester Schrumpfsitz, der allen Anforderungen in bezug a-tif mechanische Beanspruchungen und Gasdichtigkeit gewachsen ist.After heating the pipe end 2 to 1000, for example, and expediently even after the pipe end 1 has cooled, advantageously in liquid air, the ends pushed over one another until they are in such a position that they are after the Compensation of the temperatures of the pipes mesh. It then results in a Fixed shrink fit that meets all requirements in terms of a-tif mechanical stresses and gas tightness has increased.
