Description

Elastische, mit Ventilklappen versehene Platte für Membranpumpen Gegenstand der Erfindung ist eine elastische, mit Ventilklappen versehene Platte für Membranpumpen, die insbesondere zum Fördern von Säuren, Laugen und anderen Flüssigkeiten, die Metalle angreifen, dienen.Elastic plate with valve flaps for diaphragm pumps object the invention is an elastic plate for diaphragm pumps provided with valve flaps, those in particular for pumping acids, alkalis and other liquids, the metals attack, serve.

Bei derartigen Pumpen ist es bereits belfannt, die Membran so anzuordnen, daß sie gleichzeitig eine Abdichtung zwischen Pumpengehäuse und Anschlußstück bildet. Das Neue der Erfindung besteht darin, daß die nach ihrem freien Ende zu keilförmig verdickten Ventilklappen durch eingebettete federnde Metalleinlagen versteift sind. Diese Einlagen besitzen Aussparungen, wodurch sie biegsam werden und sich den Rundungen der Durchflußkanäle anpassen können.With pumps of this type, it is already known to arrange the membrane in such a way that that it also forms a seal between the pump housing and connector. The novelty of the invention is that it is too wedge-shaped after its free end thickened valve flaps are stiffened by embedded resilient metal inserts. These inserts have recesses, which make them flexible and the curves adjust the flow channels.

In der Zeichnung ist der Erfindungsgegenstand dargestellt,- und zwar zeigt: Fig. i den Querschnitt durch ein Pumpengehäuse, Fig. z eine Ventilplatte in der Ansicht, Fig.3 dieselbe Ventilplatte im Querschnitt.In the drawing, the subject of the invention is shown - namely shows: FIG. i the cross section through a pump housing, FIG. z a valve plate in the view, Figure 3 the same valve plate in cross section.

Zwischen dem Membrangehäuseteil a, das, da es mit der aggressiven Flüssigkeit nicht in Berührung kommt, aus irgendeinem geeigneten Material, z. B. Eisen, hergestellt sein kann, und dem aus widerstandsfähigem Werkstoff, z. B. keramischer Masse, Hartgummi usw., hergestellten Membrangehäuseteil c ist in an und für sich bekannter Weise eine Gummimembran b angeordnet.Between the diaphragm housing part a, that, as it is with the aggressive Does not come into contact with the liquid, made of any suitable material, e.g. B. Iron, can be made, and made of durable material, e.g. B. ceramic Mass, hard rubber, etc., produced membrane housing part c is in and of itself a known manner a rubber membrane b is arranged.

Die Bewegungen der Membran werden auf die Klappen dl und d2, die in die Dichtung d eingearbeitet sind, übertragen und bewirken hierdurch das Minen und Schließen der Saugleitung f bzw. der Druckleitung g.The movements of the diaphragm are caused by the valves dl and d2, which are in the seal d are incorporated, transferred and thereby cause the mining and Closing the suction line f or the pressure line g.

Die Klappen dl und d2 besitzen in das Gummimaterial eingelegte Federn 1a, die mit Schlitzen i versehen sind. Diese Schlitze ermöglichen es, daß die Verbindung des Klappenmaterials in sich gewahrt bleibt und daß dadurch die Klappen sich gut an die Begrenzungsflächen k anschmiegen können und somit den Durchflußquerschnitt nicht verändern.The flaps dl and d2 have springs embedded in the rubber material 1a, which are provided with slots i. These slots allow the connection the flap material is preserved in itself and that thereby the flaps are good can cling to the boundary surfaces k and thus the flow cross-section Don `t change.

Sinngemäß läßt sich diese Erfindung auch bei direkten Kolbenpumpen anwenden.This invention can also be used analogously with direct piston pumps use.
