Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Gasbeflutung von zwei miteinander zu verschweißenden rohrförmigen Elementen, mit einem in den Verbindungsbereich der beiden rohrförmigen Elemente einführbaren Gaszuführkörper und mit beiderseits des Gaszuführkörpers angeordneten nabenförmigen Elementen, auf denen jeweils gegen das Innere des jeweiligen rohrförmigen Elementes abdichtende, nachgiebige, scheibenförmige Dichtelemente angeordnet sind.The The invention relates to a device for gas flooding of two with each other to be welded tubular Elements, with one in the connection region of the two tubular elements insertable Gas feed body and arranged with both sides of the Gaszuführkörpers hub-shaped Elements on each of which against the interior of the respective tubular element sealing, resilient, disc-shaped sealing elements arranged are.
Solche Vorrichtungen werden z.B. bei der Herstellung von hochwertigen Schweißverbindungen zwischen Rohren und/oder Behältern an niedrig- und hochlegierten Stählen eingesetzt, um einem begrenzten Rohrabschnitt im Bereich der herzustellenden Schweißnaht ein Schutzgas zuzuführen, welches das Verzundern der Schweißnaht und der Übergangszonen verhindert.Such Devices are e.g. in the manufacture of high quality welded joints between Pipes and / or containers on low and high alloy steels used to produce a limited pipe section in the range of Weld to supply a protective gas, which the scaling of the weld and the transition zones prevented.

Aufgabe der Erfindung ist es, eine gattungsgemäße Vorrichtung so weiterzuentwickeln, dass der Aufbau der Dichtelemente wesentlich vereinfacht wird.task the invention is to develop a generic device so, that the structure of the sealing elements is substantially simplified.
Diese Aufgabe wird bei einer Vorrichtung der eingangs bezeichneten Art erfindungsgemäß dadurch gelöst, dass auf jedem nabenförmigen Element jeweils wenigstens zwei voneinander beabstandete Dichtelemente angeordnet sind, welche jeweils einen inneren ringförmigen metallischen Kern und einen äußeren Scheibenkörper aus einem elastomeren Material aufweisen.These Task is in a device of the type described according to the invention thereby solved, that on each hub-shaped Element in each case at least two spaced-apart sealing elements are arranged, each having an inner annular metallic Core and an outer disk body an elastomeric material.
Durch diese Gestaltung wird der Herstellungs- bzw. Materialaufwand deutlich verringert, da die Dichtelemente nicht mehr vollständig aus einem elastomeren Material, insbesondere Silikonkautschuk oder dgl., bestehen, sondern einen inneren metallischen Kern (vorzugsweise aus Edelstahl) aufweisen. Durch diese Gestaltung werden nicht nur die Herstellungs- und Materialkosten verringert, sondern die Stabilität der Dichtelemente im Kernbereich wird vergrößert. Ferner ist von wesentlichem weiteren Vorteil, dass die Gestaltung der Dichtelemente es ermöglicht, für den jeweiligen Einsatzzweck der Vorrichtung grundsätzlich beliebig viele einzelne Dichtelemente nebeneinander auf dem jeweiligen nabenförmigen Element anzuordnen, so dass diese Dichtelemente als Standardbauteile verwendet werden können und es keiner für den jeweiligen Anwendungszweck angepasster spezieller Dichtelemente bedarf.By This design is the manufacturing or material costs clearly decreases because the sealing elements are no longer completely out an elastomeric material, in particular silicone rubber or the like exist, but an inner metallic core (preferably made of stainless steel). This design will not only reduces the manufacturing and material costs, but the stability of the sealing elements in the core area is enlarged. Further is of significant further advantage that the design of the sealing elements allows, for the each purpose of the device basically any number of individual Sealing elements side by side on the respective hub-shaped element to arrange so that these sealing elements used as standard components can be and no one for it the particular application adapted special sealing elements required.
Bevorzugt ist der metallische Kern des jeweiligen Dichtelementes in den Scheibenkörper eingesetzt. Dies kann z.B. durch Umspritzen des metallischen Kerns geschehen.Prefers the metallic core of the respective sealing element is inserted into the disk body. This can e.g. done by encapsulation of the metallic core.
Es kann auch vorgesehen sein, dass der Scheibenkörper des jeweiligen Dichtelementes auf den ringförmigen metallischen Kern auf vulkanisiert ist.It can also be provided that the disk body of the respective sealing element on the ring-shaped metallic core is vulcanized on.
Besonders bevorzugt ist vorgesehen, dass zwischen den Dichtelementen Distanzringe angeordnet sind. Durch geeignete Auswahl der Distanzringe bzw. deren Breite können die Dichtele mente dann im jeweils gewünschten Abstand angeordnet werden.Especially It is preferably provided that spacer rings between the sealing elements are arranged. By appropriate selection of the spacers or their Width can the Dichtele elements then arranged at the desired spacing become.
In weiterer Ausgestaltung ist vorgesehen, dass der Scheibenkörper des jeweiligen Dichtelementes eine umlaufende, sich radial nach außen verjüngende Dichtlippe aufweist. Aufgrund dieser Gestaltung kann sich das Dichtelement außenseitig besonders flexibel und dichtend an die jeweilige Rohrwandung anlegen.In Another embodiment provides that the disk body of the respective sealing element a circumferential, radially outwardly tapered sealing lip having. Due to this design, the sealing element can externally create a particularly flexible and sealing to the respective pipe wall.
Wie an sich bekannt, besteht der jeweilige Scheibenkörper bevorzugt aus Silikon, insbesondere Silikonkautschuk.As known per se, the respective disk body is preferably made of silicone, in particular silicone rubber.
Um die Vorrichtung auch für gekrümmte Rohrabschnitte geeignet zu machen, ist in weiterer Ausgestaltung vorgesehen, dass die beiden nabenförmigen Elemente über einen Universalgelenkkörper miteinander verbunden sind.To the device also for curved To make pipe sections suitable, is provided in a further embodiment that the two hub-shaped elements are connected to each other via a universal joint body.
Dieser Universalgelenkkörper ist dabei bevorzugt als Wendelwellschlauch ausgebildet, welcher vorzugsweise durch eine Drahtgewebeklöppelung verstärkt ist.This Universal joint body is preferably formed as a spiral corrugated hose, which preferably reinforced by a Drahtgewebeklöppelung.
