Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei diesem Rückstauventil für Siel- und Abflufsleitungen besteht das Eigenthümliche darin, dafs zum Abschlufs der Sielleitung gegen Stauwasser eine um einen Zapfen drehbare, mittels eines Dichtungsringes gegen eine Verengung des Sielrohres anliegende Klappe verwendet wird, welche aus leichtem Material, z.B. Hartgummi, hergestellt und mit einem inneren Hohlraum versehen ist, welcher bewirkt, dafs durch das abfliefsende Wasser die Klappe einen Auftrieb bekommt, sich infolge dessen leicht öffnen kann -und dem Wasser leichten Durchgang ermöglicht. With this backflow valve for sewer and waste pipes The peculiar thing is that it closes the sewer against backwater one rotatable about a pin, against a constriction by means of a sealing ring the flap adjacent to the sewer pipe is used, which is made of light material, e.g. hard rubber, is made and provided with an internal cavity, which causes that through the draining water the flap gets a lift, as a result of which it can open easily can -and allows the water to pass easily.

In der Zeichnung ist die Erfindung dargestellt.The invention is shown in the drawing.

Fig. ι und 2 zeigen das Ventil im Querschnitt bezw. von der Seite und vom Ende gesehen, und Fig. 3 ist Grundrifs zu Fig. 1.Fig. Ι and 2 show respectively the valve in cross section. from the side and from the end and FIG. 3 is a basic outline for FIG. 1.

α ist das Sielrohr, dessen Einlauf eine Verengung b besitzt, c ist die um Zapfen d drehbare, aus Hartgummi hergestellte, mit einem Dichtungsringe e versehene Klappe, welche geneigt liegt und durch Stauwasser gegen die Verengung b geprefst wird, f ist ein Hohlraum, welcher bewirkt, dafs beim Eintritt des Wassers in Richtung des Pfeiles Fig. 1 das Ventil sich leicht hebt und in die punktirte Stellung gelangt. Die Klappe schwimmt dann auf dem Wasser und gestattet diesem leichten Durchgang, worauf sie durch ihr Eigengewicht wieder in ihre frühere Lage zurückkehrt. Die Wirkungsweise des Ventils erfolgt vollständig selbsttätig, sowohl beim Durchlassen des Wassers als auch beim Abschlufs gegen Stauwasser. α is the sewer pipe, the inlet of which has a constriction b , c is the flap made of hard rubber rotatable around pin d , provided with a sealing ring e , which is inclined and is pressed against the constriction b by backwater, f is a cavity, which causes the valve to rise slightly when the water enters in the direction of the arrow Fig. 1 and comes into the punctured position. The flap then floats on the water and allows this easy passage, whereupon it returns to its previous position by its own weight. The valve works completely automatically, both when the water is let through and when it is shut off against backwater.

Claims (1)

Patent-Anspruch:Patent claim: Rückstauklappe, welche in die Rohrleitung eingebaut ist und den Abflufs von Stauwasser hindert, den Durchflufs in der anderen Richtung aber dadurch freigiebt, dafs ein mit der Klappe verbundener, dem durchzulassenden Wasser entgegenliegender Schwimmer f durch, seinen Auftrieb die Klappe öffnet. ■ ,Backwater flap, which is built into the pipeline and prevents the outflow of backwater, but opens the flow in the other direction by the fact that a float connected to the flap and opposite to the water to be let through opens the flap with its buoyancy. ■, .
