Description
Bei Ringschiebern, deren Abschlußkolben mit einem vollen Boden- versehen sind, wie sie beispielsweise bei unabgedichtet in ihrer Führungshülse laufenden. Abschlüßkölben angewandt werden müssen, treten, selbst wenn der Kolbenboden eine für die Wasserführung günstige Form hat, Unterdrücke und Wirbelungen längs des Kolbenbodens auf, die Erzitterungen des Kolbens und damit Gefährdungen des ganzen Schiebers zur Folge haben können.In the case of ring valves, the piston of which has a full bottom are, for example, when running unsealed in their guide sleeve. Final piston must be applied to kick even if the piston crown has a Has a favorable shape for the water flow, negative pressures and eddies along the piston crown on, the tremors of the piston and thus endangerment of the whole slide for Can have consequences.
Diese Unregelmäßigkeiten in der Strömung rühren von den Rippen zwischen Gehäuse und Führungshülse her und von der besonders auch bei Teilöffnungen nicht glatten Bahn des Wassers beim Übergang von der Führungshülse auf den Kolbenboden. Bei Ringschiebern mit gedichtetem Boden ist ein Ausgleich solcher Unregelmäßigkeiten dadurch erreicht worden, daß der Boden mit Löchern versehen wurde, durch die sich die Urigleichheiten der Drücke über das Innere des Kolbenbodens aus-' gleichen können, ein Verfahren, das bei Abschlußkolben, die einen vollen Boden haben müssen, nicht anwendbar ist: Bei diesen wird erfindungsgemäß, der Ausgleich der Drücke dadurch ermöglicht, daß der Kolben= boden mit einem Wässerführungsschild versehen wird, dessen Mantel und dessen ,Spitze mit Öffnungen "versehen sind, die den Ausgleich der an -ihm herrschenden verschiedenen Drücke über das Innere des Wasserführungsschildes herbeiführen. Der Wasserführungsschild wird dabei mit dem Kolben zusammengegossen oder an ihn angesetzt.These irregularities in the flow stem from the ribs in between Housing and guide sleeve and not especially with partial openings smooth path of the water at the transition from the guide sleeve to the piston crown. In the case of ring gate valves with a sealed base, such irregularities are to be compensated for has been achieved in that the bottom was provided with holes through which can compensate for the basic equality of the pressures over the inside of the piston crown, a procedure that does not apply to end flasks that must have a full bottom Applicable: With these, according to the invention, the equalization of the pressures is thereby achieved enables the piston bottom to be provided with a water guide plate, its jacket and its "tip with openings" are provided to compensate the various pressures prevailing on it via the inside of the water flow shield bring about. The water guide shield is poured together with the piston or attached to him.
In der Zeichnung ist ein mit einem erfindungsgemäß ausgestatteten Abschlußko-lben versehener Ringschieber als Ausführungsbeispiel dargestellt.In the drawing, one is equipped with a device according to the invention Abschlussko-lben provided ring slide shown as an embodiment.
Der ohne Dichtung mit reichlichem Spiel in der Führungshülse r des Ringschiebergehäuses.2 laufende Kolben 3 hat einen vollen Boden q., an den ein Wasserführungsschild 5 angegossen (links) oder angesetzt (rechts) ist. Dieser Wasserführungsschild 5 hat im Mantel und an der Spitze Öffnungen 6 und 7, ,durch ,die alle eine unruhige Strömung des Wassers entlang dem Wasserführungsschild verursachenden Druckunterschiede über den Innenraum 8 des Schildes ausgeglichen werden.The one without a seal with ample play in the guide sleeve r des Ring valve housing. 2 running piston 3 has a full bottom q., To which a water guide plate 5 is cast on (left) or attached (right). This water guide 5 has openings 6 and 7 in the jacket and at the tip, through which all have a restless Flow of water along the water flow shield causing pressure differences be balanced over the interior 8 of the shield.
