Abstract

The invention relates to a flap valve comprising a housing in which are arranged diametrically opposite through-flow openings, of which one can be closed by a valve flap provided with a sealing edge. The valve flap can be pivoted through 90 DEG out of the closed position into the open position and vice versa, about an axis lying transversely to the axis of the through-flow opening and outside the latter. An articulated lever engages on the valve flap. This articulated lever comprises a first lever, which is articulated at one end on the valve flap and, at the other end, on the free end of a second lever which, at its other end, is rigidly attached to a pivot located in a fixed position outside the through-flow cross-section. The pivot of the valve flap lies on the same side as that of the second lever and each is parallel to the other. The characterising feature of the invention is that the articulated lever 8, 9 is arranged and designed in such a way that its levers 8, 9 are in alignment in the closed position of the valve flap 7. <IMAGE>

Description

Beschreibung description

Die Erfindung betrifft ein Klappenventil, bestehend aus einem Gehäuse, in dem diametral gegenüberliegende Durchflußöffnungen angeordnet sind, von denen eine durch eine mit Dichtungsrand versehene Ventilklappe verschließbar ist, die um eine quer zur Achse der Durchflußöffnung außerhalb derselben liegende Achse um 90" aus der Schließ- in die Öffnungsstellung und umgekehrt schwenkbar ist und an der ein Doppelhebel angreift, bestehend aus einem ersten Hebel, der am einen Ende an der Ventilklappe und am anderen Ende am freien Ende eines zweiten Hebels angelenkt ist, der an seinem anderen Ende an einer außerhalb des Durchströmquerschnitts auf derselben Seite wie die Schwenkachse der Ventilklappe parallel zu dieser ortsfest liegenden Schwenkachse starr angebracht ist, wobei der Doppelhebel derart angeordnet und ausgebildet ist, daß seine Hebel in der Schließstellung der Ventilklappe fluchten. The invention relates to a flap valve, consisting of a housing, are arranged in the diametrically opposite flow openings, of which a valve flap provided with a sealing edge can be closed, which about an axis lying transversely to the axis of the flow opening outside the same 90 "from the closed to the open position and vice versa is pivotable and on which engages a double lever, consisting of a first lever at one end hinged to the valve flap and at the other end at the free end of a second lever is, which at its other end on an outside of the flow cross-section the same side as the pivot axis of the valve flap parallel to this stationary lying pivot axis is rigidly attached, the double lever arranged in such a way and is designed that its levers are aligned in the closed position of the valve flap.

Ein Klappenventil mit diesen Merkmalen ist aus der US-PS 31 82 951 bekannt. A flap valve with these features is from US-PS 31 82 951 known.

Aufgabe der vorliegenden Erfindung ist die Verbesserung derartiger Klappenventile im Hinblick auf eine Verringerung des Strömungswiderstands bei offenem Klappenventil unter gleichzeitiger Reduzierung des für die Unterbringung der Klappe in ihrer Öffnungsstellung innerhalb des Gehäuses benötigten Raumbedarfs. The object of the present invention is to improve such Flap valves with a view to reducing the flow resistance when open Flap valve while reducing the amount needed to accommodate the flap space required in its open position within the housing.

Zur Lösung dieser Aufgabe wird für ein Klappenventil mit den eingangs genannten Merkmalen erfindungsgemäß vorgeschlagen, daß die Stirnseite der Ventilklappe eine rohrsegmentförmige Ausformung aufweist, deren Achse sich bei geöffneter Ventilklappe in Strömungsrichtung erstreckt und die einen Radius R besitzt, der dem des Strömungsquerschnitts entspricht. To solve this problem is for a flap valve with the initially mentioned features proposed according to the invention that the end face of the valve flap has a tubular segment-shaped formation, the axis of which changes when the valve flap is open extends in the direction of flow and which has a radius R which is that of the flow cross-section is equivalent to.

Durch die beanspruchte Formgebung der Ventilklappe wird erreicht, daß die Ventilklappe in der Öffnungsstellung den Strömungsquerschnitt teilweise begrenzt, dadurch der Strömung keinen Widerstand entgegensetzt und diese ohne nennenswerte Verwirbelung laminar führt. Dementsprechend bietet die offene Ventilklappe keinen nennenswerten Strömungswiderstand. The claimed shape of the valve flap achieves that the valve flap in the open position partially the flow cross-section limited, so there is no resistance to the flow and this without any significant resistance Turbulence leads laminar. Accordingly, the open valve flap offers none significant flow resistance.

Darüber hinaus läßt sich auch der für die offene Ventilklappe benötigte Raum in dem Gehäuse vermindern.In addition, the one required for the open valve flap can also be used Reduce space in the housing.

In der Zeichnung ist ein Ausführungsbeispiel des erfindungsgemäßen Klappenventils dargestellt. In the drawing is an embodiment of the invention Flap valve shown.

Es zeigt: Fig. 1 Einen Längsschnitt des Ventils mit geöffneter Ventilklappe und Fig.2 Einen Längsschnitt des Ventils mit geschlossener Ventilklappe, Fig.3 Einen Schnitt längs der Linie A-B aus Fig. 1, Fig.4 Einen Schnitt längs der Linie C-D aus Fig. 1 und Fig. 5 Eine Seitenansicht des Klappenventils, Fig. 6 Einen Schnitt längs der Linie E-F. It shows: FIG. 1 a longitudinal section of the valve with the valve flap open and FIG. 2 shows a longitudinal section of the valve with the valve flap closed, FIG. 3 shows a Section along the line A-B from Fig. 1, Fig.4 A section along the line C-D from FIG. 1 and FIG. 5 a side view of the flap valve, FIG. 6 a section along the line E-F.

Gleiche Teile sind mit denselben Bezugszeichen in den verschiedenen Abbildungen versehen. The same parts are given the same reference numerals in the different Illustrations provided.

Das Gehäuse 1 des Klappenventils besitzt diametral gegenüberliegende Ein- und Auslaßöffnungen 2 bzw. 3. The housing 1 of the flap valve has diametrically opposite one another Inlet and outlet ports 2 and 3, respectively.

Die Richtung der Durchströmung des Klappenventils ist mit dem Pfeil 4 gekennzeichnet. Durch Bohrungen quer zur Strömungsrichtung 4 sind zwei Drehzapfen 5 und 6 in das Gehäuse 1 eingeschoben. An dem Drehzapfen 5 ist die Ventilklappe 7 um 90" aus der Öffnungsstellung (Fig. 1) in die Schließstellung (Fig. 2) schwenkbar befestigt. Beide Drehzapfen 5, 6 liegen außerhalb des Strömungsquerschnitts auf derselben Seite der Strömungsachse parallel zueinander An derVentilklappe 7 ist ein erster Hebel 8 angelenkt, der am anderen Ende mit dem zweiten Hebel 9 eines Doppelhebels schwenkbar verbunden ist. Die Schwenkachsen des ersten Hebels 8 sind mit 10 und 11 bezeichnet. Der zweite Hebel 9 des Doppelhebels ist an dem Drehzapfen 6 starr befestigt und mit diesem um seine Schwenkachse 12 drehbar. Die Drehung des Drehzapfens 6 kann mittels eines außerhalb des Gehäuses 1 auf den Drehzapfen 6 aufgesetzten Handbedienungshebel 13 erfolgen.The direction of flow through the flap valve is indicated by the arrow 4 marked. There are two pivot pins through bores transversely to the direction of flow 4 5 and 6 pushed into the housing 1. The valve flap is on the pivot 5 7 can be pivoted by 90 "from the open position (Fig. 1) into the closed position (Fig. 2) attached. Both pivot pins 5, 6 rest outside of the flow cross-section the same side of the flow axis is parallel to each other on the valve flap 7 a first lever 8 articulated, which at the other end with the second lever 9 one Double lever is pivotally connected. The pivot axes of the first lever 8 are denoted by 10 and 11. The second lever 9 of the double lever is on the pivot 6 rigidly attached and rotatable with this about its pivot axis 12. The rotation of the The pivot pin 6 can be placed on the pivot pin 6 by means of an outside of the housing 1 Hand lever 13 take place.

In die Einströmöffnung 2 ist der Anschlußstutzen 14 eingeschoben oder eingeschraubt, und der Zwischenraum ist durch die Ringdichtung 15 abgedichtet. Der Anschlußstutzen 14 kann auch angeflanscht sein. Durch das Herausnehmen des Anschlußstutzens 14 wird die Zugänglichkeit zum Inneren des Gehäuses 1 des Klappenventils und die Montage und Demontage der Ventil klappe und ihres Betätigungsmechanismus vom Inneren her erleichtert. Dadurch wird eine durch einen Deckel verschließbare separate Montageöffnung am Gehäuse erspart. The connecting piece 14 is pushed into the inflow opening 2 or screwed in, and the space is sealed by the ring seal 15. The connection piece 14 can also be flanged. By removing the connecting piece 14 is the accessibility to the interior of the housing 1 of the flap valve and the Assembly and disassembly of the valve flap and its operating mechanism from the inside relieved. This creates a separate assembly opening that can be closed by a cover saved on the housing.

Der Anschlußstutzen 14 hat eine im Gehäuseinneren konisch sich erweiternde Dichtfläche 16, gegen die sich in der Schließstellung die Ventilklappe 7 mit einer entsprechend konischen Dichtfläche 17 legt. In die Dichtfläche 17 ist eine Ringnut 18 eingearbeitet, in der ein 0-Dichtring 19 liegt Wie Fig. 1 zeigt, sind bei geöffneter Ventilklappe 7 sowohl diese als auch die-ihre Schwenkbewegung bewirkenden Teile, nämlich der Doppelhebel 8, 9 außerhalb des Strömungsquerschnitts. Sie stören daher nicht die Durchströmung des Ventils. Der volle Strömungsquerschnitt bleibt erhalten. Die Stirnfläche 20 der Ventilklappe 7 weist eine sich mit ihrer Achse in Strömungsrichtung 4 erstreckende rohrsegmentförmige Ausformung 21 auf. The connection piece 14 has a conically widening inside the housing Sealing surface 16 against which the valve flap 7 is in the closed position with a corresponding conical sealing surface 17 sets. In the sealing surface 17 is an annular groove 18 incorporated, in which there is an O-sealing ring 19, as shown in FIG Valve flap 7 both these and the parts causing their pivoting movement, namely the double lever 8, 9 outside the flow cross-section. They are therefore disturbing not the flow through the valve. The full flow cross-section is retained. The end face 20 of the valve flap 7 has its axis in the direction of flow 4 extending tubular segment-shaped formation 21.

Bei geöffneter Ventilklappe (Fig. 1) sind die beiden Hebel 8, 9 des Doppelhebels gegeneinander abgewinkelt, während sie bei geschlossener Ventilklappe (Fig. 2) mit ihren Längsachsen fluchten. Sämtliche Schwenkachsen 10, 11, 12 liegen dabei auf einer einzigen Geraden, wie aus Fig. 2 hervorgeht. When the valve flap is open (Fig. 1), the two levers 8, 9 of the Double levers angled against each other while they are with the valve flap closed (Fig. 2) align with their longitudinal axes. All pivot axes 10, 11, 12 are located while on a single straight line, as can be seen from FIG.

Fig. 1 zeigt, daß die Drehzapfen 5 und 6 außerhalb des Strömungsquerschnitts aber möglichst nahe an seiner Peripherie etwa auf gleicher Höhe liegen, um an Bauhöhe zu sparen. Fig. 1 shows that the pivot pins 5 and 6 outside the flow cross-section but as close as possible to its periphery, about the same height, in order to be at construction height to save.
