Description

Die Erfindung betrifft eine elastische Rückschlagklappe aus Gummi
oder ähnlichem Werkstoff zum Absperren einer Öffnung durch den Rückfluß eines Gas- oder Flüssigkeitsstromes.The invention relates to an elastic non-return valve made of rubber
or similar material for blocking an opening by the backflow of a gas or liquid stream.

Derartige Klappen werden z.B. in Luftleitungen parallel betriebener Ventilatoren oder in Flüssigkeitsleitungen parallel arbeitender
Pumpen eingebaut und dienen als Kurzschlußklappen für den Fall, daß einer der Ventilatoren bzw. eine der Pumpen ausfällt.Such flaps are, for example, fans operated in parallel in air lines or fans operating in parallel in liquid lines
Pumps installed and serve as short-circuit flaps in the event that one of the fans or one of the pumps fails.

Die Elastizität der Klappen hat den Vorteil, daß zusätzliche Abdichtungsmittel am Klappenrand oder Klappenrahmen entbehrlich sind. Nachteilig ist jedoch, daß die Elastizität zu Flatterbewegungen der Klappen führt.The elasticity of the flaps has the advantage that additional sealing means are dispensable on the flap edge or flap frame. The disadvantage, however, is that the elasticity leads to flutter movements Flaps leads.

Die Erfindung hat sich die Aufgabe gestellt, eine elastische Rückschlagklappe zu schaffen, die ohne den Nachteil der Flatterbewegungen den Vorteil der einfachen Abdichtung beibehält.The object of the invention is to provide an elastic non-return valve to create that maintains the advantage of simple sealing without the disadvantage of fluttering movements.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Klappenflache bis auf einen ringsumlaufenden, auf dem Öffnungsrand aufliegenden Randstreifen durch eine Versteifungsplatte bewehrt wird.This object is achieved according to the invention in that the flap surface is reinforced by a stiffening plate except for a circumferential edge strip resting on the opening edge.

Zur Senkung des durch das Gewicht der Versteifungsplatte bedingten Druckverlustes sieht die Erfindung vor, das Gewicht der Klappe durch in die Versteifungsplatte eingestanzte Durchbrüche zu vermindern.To reduce the caused by the weight of the stiffening plate Pressure loss, the invention provides to reduce the weight of the flap by punching holes in the stiffening plate.

Eine weitere Senkung des Druckverlustes erzielt die Erfindung dadurch, daß die Klappe mit einer vorstehenden Leiste versehen ist, die in der Offenstellung der Klappe in den Strömungsweg des austretenden Mediums geringfügig vorsteht. Durch die vorstehende Leiste wird die Klappe weiter geöffnet und der Druckverlust entsprechend vermindert.The invention achieves a further reduction in pressure loss by that the flap is provided with a protruding bar, which in the open position of the flap in the flow path of the exiting Medium protrudes slightly. The flap is opened further by the protruding bar and the pressure loss is correspondingly increased reduced.

Schließlich sieht die Erfindung vor, die Rückschlagklappe aus mehreren Gummilamellen zu bilden, die sich in der Schließstellung schuppenartig überdecken. Durch die Unterteilung der Klappe in mehrere Gummilamellen ist eine geringere Öffnungskraft erforderlich, als bei einer einstückigen Klappe. Die Unterteilung der Klappe hat aufgrund der geringen Masse der einzelnen Lamellen den weiteren Vorteil, daß auftretende Schwingungen der Lamellen schnell abklingen.Finally, the invention provides the check valve from several To form rubber lamellas that overlap like scales in the closed position. By dividing the flap into several Rubber slats require less opening force than with a one-piece flap. The subdivision of the flap has due The low mass of the individual lamellas has the further advantage that vibrations of the lamellas that occur quickly subside.

In der Zeichnung ist ein Äusführungsbeispiel der Erfindung schematisch dargestellt.An embodiment of the invention is shown schematically in the drawing shown.

Fig. 1 zeigt im Längsschnitt ein Kanalende, an dessen Öffnung eine in Lamellen unterteilte elastische Rückschlagklappe angebracht ist undFig. 1 shows in longitudinal section a channel end, at the opening an elastic non-return flap divided into lamellas is attached and

Fig. 2 eine Lamelle in Ansicht.Fig. 2 shows a lamella in view.

Am Öffnungsrand 1 eines Kanals 2 sind über die Öffnungsbreite horizontal verlaufende Leisten 3 angebracht, an denen jeweils der obere Bandstreifen einer aus elastischem Werkstoff bestehenden Lamelle 4 befestigt ist. Durch die Elastizität der Lamellen sind zusätzliche Gelenke oder Scharniere entbehrlich.At the opening edge 1 of a channel 2 are horizontal across the opening width running strips 3 attached, on each of which the upper strip of tape of a lamella 4 made of elastic material is attached. Due to the elasticity of the slats, additional joints or hinges are unnecessary.

Die Lamellen 4 sind bis auf einen sich auf den Öffnungsrand 1 auflegenden Randstreifen 5 durch eine dünne Platte 6 versteift. Die Versteifungsplatte weist zur Gewichtsverminderung noch Durchbrüche auf. Eine sich senkrecht von der Lamellenebene abhebende Leiste 8 steht in der Offenstellung der Lamellen im Strömungsweg des austretenden Mediums und vermindert dadurch die Kraft, die erforderlich ist, um die Lamellen in der horizontalen Offenstellung zu halten. In der Schließstellung überdecken sich die Lamellen 4 schuppenartig und stützen sich auf Querstangen 9 am Öffnungsrand 1 des Kanals 2 ab.The lamellae 4 rest on the opening edge 1 except for one Edge strips 5 stiffened by a thin plate 6. The stiffening plate has openings to reduce weight on. In the open position of the lamellas, a bar 8 that lifts up perpendicularly from the plane of the lamellas is in the flow path of the exiting Medium and thereby reduces the force that is required to hold the slats in the horizontal open position. In the closed position, the slats 4 overlap like scales and are supported on transverse rods 9 on the opening edge 1 of the channel 2.
