Description

Die Erfindung bezieht sich auf Klappenventile und ist im wesentlichen dadurch gekennzeichnet, daß die Ventilklappe aus elastischem Material, 'beispielsweise Gummi, besteht und an ihrem Umfang mit einer .rundherum laufenden Versteifungsleiste versehen ist.The invention relates to flap valves and is essentially characterized in that the valve flap made of elastic material, 'for example Rubber, consists and on its circumference with a stiffening strip running all around is provided.

Im folgenden ist die Erfindung an Hand zweier in der Zeichnung veranschaulichter Ausführungsformen näher beschrieben.The invention is illustrated below with reference to two in the drawing Embodiments described in more detail.

Fig. i zeigt das Ventil in Vorderansicht und f Fig. 2 im Schnitt; Fig. 3 stellt ebenfalls im Schnitt eine etwas @abgeän:derte Ausführungsform dar.Fig. I shows the valve in a front view and f Fig. 2 in section; Fig. 3 also shows a somewhat modified embodiment in section.

Das Klappenventil, das von in einem Kanalsystem für ein Gas, beispielsweise Luft, auftretenden Druckdifferenzen betätigt wird, besteht aus einer schwenkbar angeordneten Ventilklappe i, dieaus elastischem Material, z. B. Gummi, hergestellt und an ihrem Umfang mit einer rundherum laufenden Versteifungsleiste :2 versehen ist. In den gezeigten- Ausführungsbeispielen weist die Ventilklappe i ein in einem Stück damit hergestelltes, nicht versteiftes Ohr 3 auf, reit .dessen Hilfe die Ventilklappe mit einem am Ventilgehäuse q. angebrachten Befestigungsteil 5 schwenkbar verbunden ist.The flap valve that is used in a duct system for a gas, for example Air, pressure differences occurring is actuated, consists of a pivotable arranged valve flap i made of elastic material, e.g. B. rubber made and on its circumference with a stiffening strip running all around: 2 is. In the exemplary embodiments shown, the valve flap i has one in one Piece of unstiffened ear 3 made with it, rides the valve flap with its help with one on the valve body q. attached fastening part 5 pivotally connected is.

Der Sitz der Ventilklappe i besteht bei der Ausführungsform gemäß Fig. 2 aus einem Ringflansch 6, der sich um die Luftdurchströmöffnung 7 herum erstreckt. Wie aus Fig. 2 hervorgeht, öffnet sich die Ventilklappe in der durch den Pfeil B. angegebenen Richtung. Sollte somit ein Überdruck auf der Seite vorhanden sein, von der die Luft zuströmt,- so bringt dieser Überdruck die Ventilklappe i dazu, auszuschwingen und dämit das Ventil zu öffnen. Ist dagegen der Druck an der entgegengesetzten :Seite gräßer, so wird die Ventilklappe i gegen den Sitz 6 gepreßt, wobei infolge der Elastizität und der Umkreisversteifung der Ventilklappe eine :äußerst gute Dichtung erzielt wird.The seat of the valve flap i exists in the embodiment according to 2 from an annular flange 6 which extends around the air throughflow opening 7. As can be seen from Fig. 2, the valve flap opens in the direction indicated by the arrow B. specified direction. Should there be overpressure on the side of which the air flows in, - this overpressure causes the valve flap i to swing out and thus to open the valve. If, on the other hand, the pressure is on the opposite: side larger, the valve flap i is pressed against the seat 6, due to the elasticity and the circumferential stiffening of the valve flap: an extremely good seal achieved will.

Die in Fig. 3 gezeigte Ausführungsform unterscheidet sieh von der gemäß Fig. 2 nur dadurch, daß der Ringflansch 6 mit einer Verlängerungshülse g aus Gummi od. dgl. versehen ist, an der die Ventilklappe bei geschlossenem Ventil dichtend anliegt. Hierdurch ist das Ventil imstande, in geschlossener Lage bei voller Dichtung gewisse Pulsationen des Luftdruckes aufzunehmen.The embodiment shown in FIG. 3 differs from the see according to FIG. 2 only in that the annular flange 6 with an extension sleeve g from Rubber or the like is provided on which the valve flap seals when the valve is closed is applied. This enables the valve to be in the closed position with a full seal to absorb certain pulsations of the air pressure.

Die Erfindung ist natürlich nicht auf die dargestellte und beschriebene Ausführungsform begrenzt, vielmehr kann diese im Rahmen der Erfindung in vielfacher Weise geändert werden.The invention is of course not limited to that shown and described Embodiment is limited, but can in many ways within the scope of the invention Way to be changed.
