Description
Es ist bekannt, Gehäuse für Absperrschieber aus dem Vollen zu schmieden oder durch Schweißen aus Rohren oder Formstücken herzustellen. Das erste Verfahren, das gesamte Gehäuse in einem Stück aus dem Vollen zu schmieden, wird bei Gehäusen größerer Abmessungen zu teuer. Das bisher bekannte Zusammenschweißen des Gehäuses aus Rohrstücken ist billig, hat aber insbesondere für höchste Drücke und Temperaturen gewisse Nachteile.It is known to forge housings for gate valves from solid material or by welding from pipes or fittings. The first procedure Forging the entire housing in one piece from solid is called for with housings larger dimensions too expensive. The previously known welding together of the housing made of pipe pieces is cheap, but has especially for the highest pressures and temperatures certain disadvantages.
Das Schiebergehäuse wird durch die Dehnungskräfte der Rohrleitungen zusätzlich sehr stark beansprucht. Es ist daher erforderlich, das Mittelstück, an welches die Rohrleitung durch Flansche oder durch Anschweißen befestigt wird, besonders widerstandsfähig auszubilden, während der Oberteil und Unterteil des Gehäuses normal ausgebildet werden kann. Bei dem Gehäuse nach der Erfindung besteht der in der Strömungsrichtung liegende Teil aus einem geschmiedeten, sehr kräftig gehaltenen starkwandigen Mittelstück. Der Oberteil und bei Vorhandensein eines Leitrohres im Schieberabschluß der Unterteil bestehen aus handelsüblichen entsprechend geformten Rohrstücken. An das kräftig . gehaltene Mittelstück können weiter die Anschlußstutzen mit Flanschen angeschweißt werden. Das Mittelstück kann auch direkt mit der Rohrleitung verschweißt werden: In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.The valve body is made by the expansion forces of the pipelines also very heavily used. It is therefore necessary to attach the middle piece which the pipeline is fastened by flanges or by welding, especially train resistant, while the upper part and lower part of the housing normal can be trained. In the case of the housing according to the invention, this exists in the direction of flow lying part made of a forged, very strong, thick-walled middle piece. The upper part and, if there is a guide tube in the slide closure, the lower part consist of commercially available, appropriately shaped pieces of pipe. The vigorous . The center piece held can also be welded to the connecting pieces with flanges will. The middle piece can also be welded directly to the pipeline: In the drawing, the invention is shown in one embodiment.
Fig.I zeigt einen Schnitt, dessen Ebene durch die Hauptströmungsachse und durch die Spindelachs:e des Schiebergehäuses führt; Fig. II gibt ein Gehäuse in Seitenansicht mit eingebautem Schieber, aufgesetztem Gehäuseaufbau und einem Bodenansatz für das Leitrohr wieder.Fig.I shows a section, the plane of which through the main flow axis and through the spindle shaft: e of the valve body; Fig. II gives a housing in side view with built-in slide, attached housing structure and a Base attachment for the guide scope again.
Das Mittelstück i ist der Schmiedekörper, auf den nach der Bedienungsseite zu ein handelsübliches dünnwandiges Rohrstück 2 aufgeschweißt ist. Auf den Flansch dieses Rohrstückes ist; wie Fig. II erkennen läßt, der Aufsatz 6 mit Stopfbüchse 5 für die Spindel aufgeschraubt. Seitlich sind an die Öffnungen des geschmiedeten Mittelstückes als Anschlußstutzen für die Rohrleitungen dienende handelsübliche Flänschrohrstücke q. angeschweißt. Die Rohrleitungen können aber auch unmittelbar an .die Öffnungen des Mittelstückes angeschweißt sein. Die Schweißnähte sind mit $ bezeichnet.The middle piece i is the forged body on the operator side is welded to a commercially available thin-walled pipe section 2. On the flange this piece of pipe is; as can be seen in FIG. II, the attachment 6 with a stuffing box 5 screwed on for the spindle. Laterally are forged to the openings of the Central piece serving as a connecting piece for the pipelines Flange pipe pieces q. welded on. The pipelines can also be used directly be welded to .the openings of the middle piece. The welds are with $ denotes.
