Description

Es sind Absperrorgane für Druckmittelleitungen bekannt, bei denen das Verschlußstüek rohrförmig gestaltet ist, wobei das flüssige oder gasförmige Druckmittel in derOffenstellung durch dieses, Rohr strömt und durch Öffnungen in einem zweiten, feststehenden Einsatzrohr abfließt. In der Schließstellung «>erden diese seitlichen Öffnungen im Einsatzrohr durch das Verschlußstück abgedeckt. Bei diesen bekannten Absperrorganen muß also, das Druckmittel mehrfach seine Richtung wechseln, wodurch der Strömungswiderstand des geöffneten Absperrorgans beträchtlich groß ist:.There are shut-off devices for pressure medium lines known in which the closure piece is tubular, the liquid or gaseous Pressure medium in the open position flows through this pipe and through openings in a second, fixed insert pipe drains. In the closed position «> earth these lateral openings in the insert tube covered by the closure piece. at These known shut-off devices must therefore, the pressure medium several times its direction change, whereby the flow resistance of the open shut-off element is considerable big is :.

Gemäß der Erfindung kann bei derartigen Absperrorganen der Strömungswiderstand dadurch sehr wesentlich vermindert werden, d.aß die Offnun,-en im Einsatzrohr schräg im Sinn der Bewegungsrichtung des Druckmittels verlaufen und dieses feststehende Einsatzrohr die Form eines in eine Spitze auslaufenden Rotationskörpers hat. Als besonders günstig hat sich dabei die Form eines Rotationssinoides ergeben, d. h. eines durch Rotation eines Teils einer Sinuslinie entstehenden Rotationskörpers.According to the invention, the flow resistance of such shut-off devices thereby very substantially reduced, i.e. the openings in the insert tube are inclined run in the sense of the direction of movement of the pressure medium and this stationary Insert tube has the shape of a body of revolution tapering into a point. as The shape of a rotational sinoid has turned out to be particularly favorable, d. H. a solid of revolution created by rotating part of a sine line.

Ein Ausführungsbeispiel des Gegenstandes der Erfindung ist in der Abbildung dargestellt. Indem Gehäuse i ist das rohrförmige Verschlußstück 2 in axialer Richtung verschiebbar. In der dargestellten Offenstellung strömt das Druckmittel in axialer Richtung durch das Rohr 2 und. tritt durch Öffnungen 3 in dem feststehenden. Einsatzrohr.I in einen ringförmigen Raum >, aus dem es ,v ieder in der gleichen Richtung, in der der Zufluß zu dem Rohr :2 erfolgte, durch das Rohr wieder abfließt. Dabei sind erfindungsgemäß die Öffnungen 3 schräg gestellt, und das Einsatzrohr d. endet in einem Rotationsltörper 7 mit spitzbogenförmigem Querschnitt. Durch diese Formgebung d°r Austrittsöffnungen und des Einsatzrohres wird es vermieden, daß das Druckmittel wie hei den bekannten Anordnungen seine Strömungsrichtung mehrmals um 9o°' ändern. muß. Es bleibt vielmehr die allgemeine Strömungsrichtung erhalten, und es werden auf diese Weise die Strömungswiderstände auf einen geringen. Wert reduziert.An embodiment of the subject matter of the invention is in Figure shown. In the housing i, the tubular closure piece 2 is in the axial direction Movable direction. In the illustrated open position, the pressure medium flows in the axial direction through the tube 2 and. enters through openings 3 in the fixed. Insertion tube.I into an annular space> from which it, different in the same Direction in which the inflow to the pipe: 2 took place, flows out again through the pipe. According to the invention, the openings 3 and the insert tube are inclined d. ends in a rotary body 7 with an ogival cross-section. Through this Shaping the outlet openings and the insert tube, it is avoided that the Pressure medium, as in the known arrangements, reverses its direction of flow several times Change 9o ° '. got to. Rather, the general direction of flow is retained, and in this way the flow resistances are reduced to a low level. value reduced.

In der Schließstellung sind die Öffnungen 3 durch das rohrförmigeVerschlußstück2 abgedeckt, und die Vorderkante des Rohres -2 liegt diehtschließend gegen einen Sitz B.In the closed position the openings 3 are through the tubular closure piece 2 covered, and the front edge of the tube -2 is then close against a seat B.

Die Bewegung des Verschlußstückes 2 kann in beliebiger Weise z. B. mittels eines Schraubenspindel- oder Hebelmechanismus erfolgen. Besonders zweckmäßig ist es, die Bewegung des Verschlußstückes durch das Druckmittel ,selbst: zu steuern, was beispielsweise dadurch geschehen kann, daß das Rohr an seiner Außenseite in der Mitte einen Verstärkungsring 9 aufweist, welcher in einer entsprechenden, zylindrischen Erweiterung des Gehäuses i dichtschließend gleitet. Durch Zuleitung von Druckmittel, das der Hauptdruckmittelleitung an einer vor dem. Absperrorgan liegenden Stelle entnommen und durch Hähne oder Schieber der einen oder anderen Seite des Ringes zugeleitet wird, kann das Öffnen bzw.. Schließen des Absperrorgans in: einfacher Weise bewirkt werden.The movement of the closure piece 2 can be carried out in any manner, for. B. be done by means of a screw spindle or lever mechanism. Particularly useful is to control the movement of the locking piece by the pressure medium itself: what can happen, for example, that the tube on its outside in the center has a reinforcing ring 9, which in a corresponding, cylindrical Extension of the housing i slides tightly. By supplying pressure medium, that of the main hydraulic line on one before the. Shut-off device lying position taken and through taps or slides on one side or the other of the ring is supplied, the opening or closing of the shut-off device can be easier Way to be effected.
