Description

Vorstehende Erfindung stellt einen Rohrschieber dar, der sowohl in seiner Form als auch in seiner Abdichtungsart den hohen Anforderungen des in neuester Zeit zur Anwendung gelangten Höchstdruckdampfbetriebes genügen soll.The above invention provides a pipe valve that is both in its shape as also in its sealing type the high requirements of the recent time to use reached maximum pressure steam operation should suffice.

Rohrschieber mit Sitzdichtung und Kolbenringen sind bekannt. Die Kolbenringe dieser Art besitzen jedoch außer der eigenen Spannung keine mechanisch hervorgerufene Spannkraft, die geeignet ist, einen beliebig starken Anpressungsdruck an die Dichtflächen zum vollständigen Abdichten gegen Höchstdruck zu erzeugen.Pipe slides with seat seals and piston rings are known. The piston rings of this However, apart from their own tension, Art have no mechanically generated tension force that is suitable for any strong contact pressure on the sealing surfaces for complete sealing against maximum pressure to create.

Diese Eigenschaft ist bei der vorliegenden Erfindung durch zwangläufiges Erweitern des Kolbenringes, „nachstehend nunmehr Spannring genannt", vollkommen dadurch erreicht, daß zwei keilförmige Nasen angeordnet sind, die sich in der Schließstellung des Rohr- ao Schiebers in zwei ebenfalls keilförmig ausgebildete Schlitze des Spannringes einpressen und denselben erweitern, wodurch der beliebig starke Anpressungsdruck an die Dichtflächen und der vollständige Abschluß zwischen Schließschieber und Spannring gewährleistet ist. Die Einpressung der Keilnasen in die Spannringschlitze geschieht auf mechanischem Wege durch Spindeldruck.This property is in the present invention by inevitably expanding the Piston ring, "hereinafter referred to as the clamping ring", completely achieved by that two wedge-shaped lugs are arranged, which are in the closed position of the tube ao Press the slide into two also wedge-shaped slots of the clamping ring and expand the same, whereby the pressure on the sealing surfaces can be as strong as desired and the complete seal between the slide and the clamping ring is guaranteed is. The wedge noses are pressed into the clamping ring slots mechanically by means of spindle pressure.

Der Rohrschieber er in Abb. 1 der Zeichnung bewegt sich auf der Spindel mit Flachgewinde in achsialer Richtung, umfaßt in derThe pipe valve is shown in Fig. 1 of the drawing moves on the spindle with flat thread in the axial direction, includes in the

Schließstellung den Spannring b und übt durch seine Sitzdichtung d einen achsialen Druck auf die ähnliche Dichtung e im Kegeleinsatz c -aus. Durch diesen Kegeleinsatz, der einerseits in der Gewindespindel und andererseits im Gehäuse durch seinen mittels Rippen angegossenen Tragring achsial verschiebbar gelagert ist, wird der Druck auf die Keilnase g (Abb· 2) übertragen, welche sich in den Schlitz i des Spannringes einpreßt und letzteren erweitert. Zugleich drückt sich auch sein Schlitz h über die Keilnase f, da der Spannring ebenfalls achsial verschiebbar angeordnet ist, und bewirkt dadurch die gleichmäßige Erweiterung des Spannringes.In the closed position, the clamping ring b and its seat seal d exerts an axial pressure on the similar seal e in the conical insert c . Through this conical insert, which is axially displaceable on the one hand in the threaded spindle and on the other hand in the housing by its support ring cast on by means of ribs, the pressure is transferred to the wedge nose g (Fig.2), which presses into the slot i of the clamping ring and expands the latter . At the same time, its slot h is also pressed over the wedge nose f, since the clamping ring is also arranged so that it can be axially displaced, and thereby causes the clamping ring to expand evenly.
