Description

Es sind Rückschlagklappenventile bekannt, bei denen die am Ventilgehäuse angelenkte, aus Gummi hergestellte Ventilklappe einschließlich der Befestigungslasche aus einem Stück besteht. Bei diesen bekannten Ventilen hat man die aus weichem Gummi bestehende Ventilklappe, soweit sie die Abschlußöffnung verdeckt, durch 'harte Körper, wie insbesondere Rippen oder Platto ten aus Metall, verstärkt. Diese Ausführung der Ventilklappen hat den Nachteil, daß die Klappen aus zwei verschiedenen Baustoffen bestehen und die zur Versteifung der Klappe vorgesehenen Metallteile mitunter durch die Einflüsse des Betriebsmittels vorzeitig zerstört wurden.Check valves are known in which the hinged to the valve housing, valve flap made of rubber including the fastening tab consists of one piece. With these well-known Valves are made of soft rubber valve flap, as far as it covers the closing opening, by 'hard Body, such as ribs or platto in particular made of metal, reinforced. This design of the valve flaps has the disadvantage that the Flaps consist of two different building materials and those used to stiffen the flap The metal parts provided may be prematurely destroyed by the influences of the equipment became.

Die Nachteile der bekannten Ventilklappen sollen erfindungsgemäß dadurch vermieden werden, daß die Ventilklappe im Bereich der Durchgangsöffnung des Ventils aus Hartgummi und im Bereich der Befestigungsl- und Gelenkstelle aus Weichgummi hergestellt ist.The disadvantages of the known valve flaps are intended to be avoided according to the invention that the valve flap in the area of the passage opening of the valve made of hard rubber and in the area of the fastening and the joint is made of soft rubber.

In der Zeichnung ist der Erfindungsgegenstand · in einem Ausführungsbeispiel dargestellt, und zwar zeigenIn the drawing, the subject matter of the invention is shown in an exemplary embodiment, namely show

Abb. ι einen Querschnitt durch das Ventilgehäuse mit der Ventilklappe in Ansicht undFig. Ι a cross section through the valve housing with the valve flap in view and

Abb. 2 das Ventilgehäuse mit der Ventilklappe im Längsschnitt.Fig. 2 the valve housing with the valve flap in longitudinal section.

Die einstückig hergestellte Klappe besteht in ihrem unteren Teiliz aus Hartgummi; dieser kann wegen des vielfach plötzlich aufzunehmenden Flüssigkeitsdruckes durch ebenfalls aus Hartgummi bestehende Rippen b oder auch, wie bereits für Weichgummiplatten vorgeschlagen, durch innere Metalleinlagen oder Stäbe verstärkt werden. Der Teil a überdeckt die freie Durchgangsöffnung c. Um die Klappe an dem Gehäuse d gelenkig befestigen zu können, geht der Hartgummi nach oben unter dem Gehäusedeckel e aus der festen Beschaffenheit allmählich in elastischen Weichgummi über. Die oben befindliehe Lasche./.· der Klappe a. wird durch eine Zange g mit Hilfe von Schrauben Ii oder sonstigen Bcfestigungsmittehi an die Gehäusewand angepreßt. Es wird also nicht ein hartes und weiches Gummistück, das vorher mechanisch getrennt war, miteinander verbunden, sondern der weiche Gummi geht in den harten organisch über und bildet ein einheitliches Stück derselben Ursprungsmasse in verschiedener Steifheit.The one-piece flap is made of hard rubber in its lower part; Because of the fluid pressure that has to be absorbed suddenly, this can be reinforced by ribs b, which are also made of hard rubber or, as already proposed for soft rubber sheets, by inner metal inserts or rods. Part a covers the free passage opening c. In order to be able to fasten the flap to the housing d in an articulated manner, the hard rubber gradually changes upwards under the housing cover e from its solid nature to elastic soft rubber. The flap on top of the flap a. is pressed against the housing wall by pliers g with the aid of screws Ii or other fastening means. A hard and soft piece of rubber, which was previously mechanically separated, is not connected to one another, but the soft rubber organically merges into the hard one and forms a single piece of the same original mass with different degrees of stiffness.

Die Abb. 2 zeigt die Klappe sowohl in der Schließstellung als auch gemäß der gestrichelt gezeichneten Lage ζ schwebend, also im geöffneten Zustand des Ventils. Der aus einem einzigen Stück bestehende Klappenkörper weist demnach zwei verschiedene ineinander übergehende Festigkeitszustände auf.Fig. 2 shows the flap both in the closed position and according to the dashed line Drawn position ζ floating, i.e. when the valve is open. The out A single piece of valve body therefore has two different ones inside one another transient strength states.
