Description
Die Erfindung betrifft ein Klappenventil mit einem rohrförmigen Gehäuse und einem rechtwinklig dazu angeordneten kurzen Rohrstutzen etwa gleichen Innendurchme&i ;rs sowie mit einer Klappenscheibe, die um eine so weit außerhall· des Strömungsweges liegende Achse schwenkbar ist, daß die Klappenscheibe in der Offenstellung vol "kommen außerhalb des Strömungsweges liegt. Klappenventile dieser Art sind seit Jahrzehnten bekannt, beispielsweise durch die deutsche Patentschrift 83 614.The invention relates to a flap valve with a tubular housing and a right-angled Short pipe sockets arranged for this purpose with approximately the same internal diameter and with a valve disc, which is pivotable about an axis lying so far outside the hall of the flow path that the valve disc in the open position vol "come outside of the flow path. Flap valves of this type have been known for decades, for example from German patent specification 83 614.
Bei diesen bisher bekannten Klappenventilen dieser Art ist der Innendurchmesser des rohrförmigen Gehäuses größer als der Innendurchmesser der angeschlossenen Rohrleitung, damit die Klappenscheibe in dem Gehäuse von der einen in die andere Endstellung bewegt werden kann. Ein Gehäuse, dessen Innendurchmesser größer ist als der Innendurchmesser der angeschlossenen Rohrleitung, hat aber den Nachteil, daß es die Strömung des durchfließenden Mediums beeinträchtigt, und daß sich in dem Gehäuse unerwünschte Ablagerungen bilden können. Ein weiterer Nachteil eines solchen Gehäuses liegt darin, daß es erheblich teurer und schwerer ist, zumal die Stufen genormter Rohrdurchmesser so groß sind, daß entweder Gehäuse unnötig großen Durchmessers verwendet werden müssen, bei denen die genannten Nachteile besonders groß sind, oder das Gehäuse in Sonderanfertigung hergestellt werden muß, was besonders teuer ist.In these previously known flap valves of this type, the inner diameter of the tubular Housing larger than the inside diameter of the connected pipeline, so that the valve disc can be moved in the housing from one end position to the other. A housing whose inner diameter is larger than the inside diameter of the connected pipeline, but has the disadvantage that that it affects the flow of the medium flowing through, and that it is undesirable in the housing Deposits can form. Another disadvantage of such a housing is that it is considerably more expensive and heavier, especially since the steps of standardized pipe diameters are so large that either Housing of unnecessarily large diameter must be used, in which the aforementioned Disadvantages are particularly large, or the housing must be custom-made, which is special is expensive.
Aufgabe der Erfindung ist es, ein Klappenventil der eingangs genannten Art zu schaffen, das die Nachteile nicht hat. Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß der Innendurchmesser des rohrförmigen Gehäuses gleich ist dem Innendurchmesser der angeschlossenen Rohrleitung und daß die Wandung des Gehäuses an zwei einander gegenüberliegenden Stellen um so viel erweitert ist, daß die Klappenscheibe von der einen in die andere Endstellung bewegt werden kann. Da bei diesem Klappventil das rohrförmige Gehäuse den gleichen Innendurchmesser hat wie die angeschlossene Leitung, ergeben sich keine Strömungsstörurigen und keine Ablagerungen im Gehäuse. Die Herstellung der Erweiterungen der Gehäusestellen ist sehr viel billiger als die Verwendung eines Rohrstücks größeren Durchmessers für das Gehäuse. Überdies hat ein solches Klappenventil gegenüber den bekannten Klappenventilen der oben erwähnten Art den Vorteil, daß penventilen der obenerwähnten Art den Vorteil, daßThe object of the invention is to provide a flap valve of the type mentioned above, which does not have the disadvantages. According to the invention this The object is achieved in that the inner diameter of the tubular housing is the same as the inner diameter the connected pipeline and that the wall of the housing on two opposite one another Place is expanded so much that the valve disc from one end position to the other can be moved. Because in this flap valve, the tubular housing has the same inner diameter like the connected line, there are no flow disturbances and no deposits in the housing. The production of the extensions to the housing is much cheaper than using a larger diameter piece of pipe for the housing. In addition, has such a Flap valve over the known flap valves of the type mentioned above have the advantage that valve valves of the type mentioned above have the advantage that
Die Zeichnung zeigt ein Ausfühiungsbeispie] der Erfindung im Längsschnitt.The drawing shows an Ausfühiungsbeispie] the Invention in longitudinal section.
Das Gehäuse der Schließklappe besteht aus einem Rohrstück 1, dessen Innendurchmesser gleich dem Innendurchmesser der angeschlossenen Rohrleitung ist. Das Rohrstück 1 ist an beiden Enden mit Flanschen 2 versehen, mittels der es mit den beiden Enden der Rohrleitung verbunden werden kann. Das Rohrstück 1 besitzt einen rechtwinklig dazu anc.'-nl· neten Rohrstutzen3, dessen Innendurchmesser etwa ebenso groß oder etwas größer ist als der Innendurchmesser des Rohrstücks 1.The housing of the closing flap consists of a pipe section 1, the inner diameter of which is equal to Inside diameter of the connected pipeline. The pipe section 1 is flanged at both ends 2, by means of which it can be connected to the two ends of the pipeline. That Pipe section 1 has an anc .'- nl · Neten pipe socket3, the inside diameter of which is about the same or slightly larger than the inside diameter of the pipe section 1.
Auf dem Rohrstutzen 3 sitzt ein Stutzen 4. der durch einen Deckel 5 geschlossen ist, wobei zwischen Stutzen 4 und Deckel 5 eine Dichtung 6 liegt.On the pipe socket 3 sits a nozzle 4. the is closed by a cover 5, with a seal 6 lying between the connector 4 and cover 5.
Dicht oberhalb des Rohrstücks 1 und dicht neben dem Rohrstutzen 3 ist in einem Lager 9 eine Achse 7 gelagert. Das Verschwenken, der Klappe 11 um die Schwenkachse 7 erfolgt mittels eines durch ein Handrad 18 drehbares Zahnrad 16, das in eine an der Klappensjheibe 11 angelenkte Zahnstange 19 eingreift. An axle 7 is located in a bearing 9 just above the pipe section 1 and right next to the pipe socket 3 stored. The pivoting of the flap 11 about the pivot axis 7 takes place by means of a handwheel 18 rotatable toothed wheel 16 which engages in a toothed rack 19 articulated on the valve disc 11.
Das Lager 9 ist von einem Gehäuseteil 8 umgeben, das dicht mit den Teilen 1 und 3 verbunden ist. Die Achse 7 ist mit zwei einander parallelen Trägern 10 verbunden, die eine Klapoenscheibe 11 tragen. Die Klappenscheibe 11 besteht aus einer kreisförmigen Platte, an der mittels eines Klemmringes 11a eine Dichtung 12 vorgesehen ist. An zwei einander gegenüberliegenden Stellen 15 des Gehäuseteils 1, ist das Gehäuseteil 1 durch eine Ausdrückung nach außen so viel erweitert, daß diese Erweiterung 15 es der Klappenscheibe 11 ermöglicht, aus der in der Zeichnung in ausgezogenen Linien dargestellten Offenstellung in die Schließstellung geschwenkt zu werden, die in gestrichelten Linien dargestellt ist.The bearing 9 is surrounded by a housing part 8 which is tightly connected to the parts 1 and 3. The axis 7 is connected to two parallel carriers 10 which carry a flap disk 11. The valve disc 11 consists of a circular plate on which a clamping ring 11a a seal 12 is provided. At two opposite points 15 of the housing part 1 is the housing part 1 expanded so much by an expression to the outside that this extension 15 it the valve disc 11 allows from the open position shown in the drawing in solid lines to be pivoted into the closed position, which is shown in dashed lines.
Damit man den Mechanismus zur Bewegung der Klappenscheibe 11 während des Betriebes der Rohrleitung einsehen und reparieren kann, ist die Klappenscheibe 11 mit einem Rahmen 22 dicht verbunden, der sich bei geöffneter Klappe gegen eine am Stutzen 4 angebrachte Dichtung 23 anlegt.So that the mechanism for moving the valve disc 11 during operation of the pipeline can see and repair, the valve disc 11 is tightly connected to a frame 22, which, when the flap is open, rests against a seal 23 attached to the connector 4.
Im Inneren des Gehäuses 1 ist eine ringförmige Dichtung 25 befestigt, gegen die sich die Dichtung 12 der Klappe 11 in der Schließstellung dichtend legt. Grundsätzlich genügt entweder die eine Dichtung 12 oder die Dich'tung 25. Es kann also in manchen Fällen entweder die Dichtung 12 oder die Dichtung 25 fortgelassen werden; in anderen Fällen ist es zweckmäßig, beide Dichtungen vorzusehen. Die Klappe 11 kann statt der in der Zeichnung dargestellten Kreisform eine elliptische Form haben und dementsprechend in der Schließstellung in einer Ebene liegen, die in einem Winkel zur Längsachse des Gehäuseteils 1 liegt.An annular seal 25 is fastened in the interior of the housing 1, against which the seal 12 rests the flap 11 sets sealingly in the closed position. In principle, either one seal 12 is sufficient or the seal 25. So it can in some cases either seal 12 or seal 25 can be omitted; in other cases it is advisable provide both seals. The flap 11 can instead of the circular shape shown in the drawing have an elliptical shape and accordingly lie in one plane in the closed position, which lies at an angle to the longitudinal axis of the housing part 1.
