Description
Beim Betriebe von Auslaufventilen "treten bekanntlich mehr oder weniger große Ge-. rausche auf.It is well known that when operating outlet valves, more or less large events occur. rush up.
Die Beseitigung derselben soll erfindungsgemäß dadurch erreicht werden, daß bei einem Auslaufventil der Ventilsitz exzentrisch in der Ventilkammer angeordnet und der in· an sich bekannter Weise mit einer Querschnittsverengung versehene Auslaufstutzen unmittelbar hinter derselben nach der Austrittsöffnung zu düsenartig erweitert ist. - The elimination of the same is to be achieved according to the invention in that at an outlet valve, the valve seat is arranged eccentrically in the valve chamber and the In a manner known per se, outlet nozzles provided with a cross-sectional constriction directly is widened to nozzle-like behind the same after the outlet opening. -
Es sind bereits Ventile bekannt, bei denen ' vor, in oder hinter dem eigentlichen Ventilkörper im Strömungsquerschnitt ein oder mehrere Drosselkörper zur Erzielung einer Geräuschdämpfung angeordnet sind. Alle diese Drosselkörper sind mehr oder weniger kompliziert, außerdem umständlich, einzubauen und können zu Verstopfungen führen, ao Die Geräuschdämpfung der Erfindung besteht in einer weitgehenden Vermeidung der . Durchflußwirbel durch geeignete Führung des Wassers und daraus folgernd in der Ver meidung von Unterdruckstellen, an welchen die Geräusche entstehen, während die bekannten Drosselkörper lediglich den Druck am Ventil verringern, um dadurch das Geräusch zu mildern.Valves are already known in which one or more throttle bodies are arranged in front of, in or behind the actual valve body in the flow cross-section in order to achieve noise damping. All these throttle bodies are more or less complicated, also cumbersome to install and can lead to blockages, ao the noise attenuation of the invention consists in largely avoiding the. Flow vortices through appropriate guidance of the water and consequently in the avoidance of negative pressure points, where the noise occurs, while the known throttle body only reduce the pressure on the valve, thereby reducing the noise.
Ein Ventil' gemäß der Erfindung ist auf der Zeichnung dargestellt.A valve according to the invention is open shown in the drawing.
Abb.· ι zeigt einen teilweisen Mittelschnitt, _Abb. 2 einen Schnitt durch, den Auslaufstutzen. · ■Fig. Ι shows a partial middle section, _Fig. 2 a section through the outlet nozzle. · ■
Das Ventilgehäuse α hat eine zur Größe des Ventils absichtlich groß gehaltene Sitzbohrung δ, die durch den Kegele geschlossen · werden kann. Der Ventilsitz ist exzentrisch in der Ventilkammer d (Abb. 2) angeordnet. Die Kammerwandung wird an der Stelle e gerade vom Kegele berührt. Der Zweck ist, das Wasser zum Auslauf hin abzulenken, ohne daß vorher Wirbelbildungen auftreten. Damit Geräusche vermieden werden, ist ferner im Auslauf eine Einhalsung / vorgesehen, deren Durchgang möglichst nicht größer ist als der Sitzdurchgang. Infolgedessen bleibt das Wasser zwischen Sitz und Einhalsung / unter Druck und bildet keine geräuschverursachenden Wirbel. Der eigentliche Ausfluß wird durch.die Einhalsung/ bestimmt, deren Form sich zum Auslauf ende g erweitert, damit das Wasser seine hohe Geschwindigkeit verliert und den Auslauf ruhig verläßt.The valve housing α has a seat bore δ which is intentionally large in relation to the size of the valve and which can be closed by the cone. The valve seat is arranged eccentrically in the valve chamber d (Fig. 2). The chamber wall is just touched by the cone at point e. The purpose is to divert the water towards the outlet without creating vortices beforehand. In order to avoid noises, a neck / is also provided in the outlet, the passage of which is, if possible, no larger than the seat passage. As a result, the water remains between the seat and the neck / under pressure and does not form any noise-causing eddies. The actual effluent is / determined durch.die necking whose shape expands to the outlet end g, so that the water loses its high speed and leaving the spout quiet.
