"schweißverbindung zwischen zwei zylindrischen Hohlkörpern, insbesondere Behälterteilen, Rohren und dgl."«"welded connection between two cylindrical hollow bodies, in particular Container parts, pipes and the like. "«

Die Erfindung betrifft eine Schweißverbindung zwischen zwei zylindrischen Hohlkörpern, insbesondere Behälterteilen, Rohren und dgl., mit einem Zentrierring an der bei beiden Hohlkörpern gleich gestalteten Verbindungsstrelle.The invention relates to a welded connection between two cylindrical ones Hollow bodies, in particular container parts, pipes and the like., With a centering ring on the two hollow bodies identically designed connection line.

Bei hydropneumatischen Speichern ist die Verwendung eines glatten Ringes bekannt, an dessen nach innen eingebogener Unterseite eine Speicherblase anvulkanisiert ist. Zum Festlegen des Ringes in seiner Lage innerhalb des Speicherbehälters ist er mit der Schweißnaht verbunden. Die Breite der Schweißnaht im Bereich des Zentrierringes muß durch eine Vorrichtung oder dgl. besonders eingestellt werden.With hydropneumatic accumulators, the use of a smooth Ring known, on whose inwardly curved underside a storage bladder is vulcanized. To set the ring in its position within the storage container it is connected to the weld seam. The width of the weld seam in the area of the centering ring must be specially set by a device or the like will.

Verbindungsstelle vorstehenden Vorsprung aufweist, an dem zwei einander gegenüberliegende Hohlkörper anstehen und der Bestandteil der die beiden Hohlkörper miteinander verbindenden Schweißnaht ist. Die Breite des Vorsprunges an dessen Fuß ist bestimmend für den Abstand der beiden Hohlkörper und für die Breite der Schweißnaht an ihrer Wurzel. Der Vorsprung ist zugleich Bestandteil der Wurzelnaht, so daß eine innige Verbindung zwischen dem Zentrierring und der Schweißnaht vorhanden ist·Connection point has protruding projection on which two opposing hollow bodies are present and are part of the weld seam connecting the two hollow bodies to one another. The width of the projection at its foot determines the distance between the two hollow bodies and the width the weld at its root. The protrusion is also part of the root seam, so that there is an intimate connection between the centering ring and the weld seam.

Xn Weiterbildung der Erfindung ist der Vorsprung als innerhalb der Schweißnaht ringsumlaufender Wulstvorsprung ausgebildet, allein an dessen Fuß die Hohlkörper anstehen· Auf der ganzen Länge der Schweißnaht ist der Wulstvorsprung deren Bestandteil· Dieser hat nur eine linienförmige Berührung mit den Hohlkörpern, so daß die Wände der Schweißfuge durch den Wulstvorsprung nicht abgedeckt sind.Xn development of the invention is the projection than within the weld seam is formed with a bead projection running all the way around, only at the foot of which the hollow bodies stand · on the whole The length of the weld seam is the bulge protrusion, which is part of it · This only has a linear contact with the hollow bodies, so that the walls of the weld joint are not covered by the bulge protrusion.

Weitere Vorteile ergeben sich aus der nachfolgenden Beschreibung im Zusammenhang mit den Ansprüchen und der Zeichnung. In dieser sind in den Fig. 1 und 2 zwei hydropneumatische Speicher jeweils im Teillängsschnitt als Ausführungsbeispiele des Gegenstandes der Erfindung schematisch dargestellt·Further advantages emerge from the following description in connection with the claims and the drawing. In this, there are two hydropneumatic accumulators in FIGS. 1 and 2, respectively shown schematically in partial longitudinal section as exemplary embodiments of the subject matter of the invention

Zwei zylindrische Speicherteile 1 und 2 bilden im wesentlichen das Druckgefäß eines hydropneumatischen Speichers« Der Speicherteil 2 trägt ein Hochdruckgasventil 3· Zum Zentrieren der beiden Speicherteile 1 und 2 ist ein Zentrierring k vorgesehen, an dessen unterem nach innen eingebogenen? Rand eine Speicherblase 5 anvulkanisiert ist. Diese trennt den Gasteil des Speichers vom Flüssigkeitsteil. An der Unterseite des Speichertelies 1 ist ein von einem nich't dargestellten Flüssigkeitsventil überwachter Anschluß für die Zu- und Abfuhr von Flüssigkeit vorgesehen.Two cylindrical storage sections 1 and 2 form substantially the pressure vessel of a hydropneumatic accumulator "The memory section 2 carries a high-pressure gas valve 3 · To center the two storage components 1 and 2, a centering ring k is provided at the lower inwardly bent-in? Edge a storage bladder 5 is vulcanized. This separates the gas part of the storage tank from the liquid part. On the underside of the storage fabric 1, a connection monitored by a liquid valve, which is not shown, is provided for the supply and discharge of liquid.

Dieee is firmly connected to the bulge projection 6, which is the root of the weld seam 7 forms and protrudes only slightly into the weld joint «ways the wedge-shaped formation of the bead projection 6 covers this the walls of the weld joint receiving the weld 7 are not.

Während der Wulstvorsprung 6 nach Fig. 1 einseitig erhaben ausgebildet ist, ist auf der dem Wulstvorsprung 6a bei dem Ausflihrungsbeispiel nach Fig. 2 gegenüberliegenden Seite eine diesem Vorsprung entsprechende Vertiefung oder Sicke vorgesehen. Der Zentrierring kann durch spanabhebende Bearbeitung oder durct spanlose Verformung hergestellt werden· Der Wulstvorsprung braucht auf dem Zentrierring nicht ringsum zu laufen, sondern kann auch intermittierend ausgebildet sein.While the bead projection 6 according to FIG. 1 is raised on one side, a recess or bead corresponding to this projection is provided on the side opposite the bead projection 6a in the embodiment according to FIG. 2. The centering ring can be produced by machining or by non-cutting deformation · The bead projection does not need to run all around on the centering ring, but can also be designed to be intermittent.
