Description
Die Erfindung betrifft eine Drosselklappe mit einem Teller und zwei an diametral gegenüberliegenden Stellen dieses Tellers angebrachten Drehzapfen, z. B. für Leitungen von Wasserversorgungen oder Wasserkraftanlagen. The invention relates to a throttle valve with a plate and two at diametrically opposite points pivot pin attached to this plate, e.g. B. for pipes of water supplies or hydropower plants.
Bei solchen Drosselklappen ist der Teller in der Schließlage oft einem beträchtlichen Wasserdruck ausgesetzt. Um diesem Wasserdruck standhalten zu können, ist bei einer bekannten Drosselklappenbauart der Teller mit zur Drehachse senkrecht stehenden, in den Strömungsraum hineinragenden Rippen versehen, welche die Aufgabe haben, die Tellerflügel, d. h. die von der Drehachse entfernten Teile des Tellers zu tragen. Solche Rippen geben indessen keine Versteifung des Tellers gegen in einem senkrecht zur Drehachse gelegten Schnitt wirkende Biegemomente. Um diese aufnehmen zu können, ist bei dieser bekannten Bauart der Teller im Bereich der Drehachse verhältnismäßig dick ausgeführt, was aber nicht nur zu einem hohen Baustoffaufwand, sondern auch zu hohem Strömungswiderstand in der Öffnungslage der Klappe führt. Bei größeren Drosselklappen ist man zwar schon zwecks Baustoffersparnis dazu übergegangen, den mittleren, im Bereich der Drehachse liegenden Teil hohl auszuführen, was aber den Nachteil eines hohen Stromungswiderstandes in der Öffnungslage der Klappe nicht beheben kann.In the case of such throttle valves, the plate is often exposed to considerable water pressure in the closed position. In order to be able to withstand this water pressure, in a known type of throttle valve the Plate with perpendicular to the axis of rotation, in the Provide ribs protruding into the flow space, which have the task of holding the plate vanes, d. H. those of to carry parts of the plate removed from the axis of rotation. However, such ribs do not stiffen the Plate against bending moments acting in a cut perpendicular to the axis of rotation. To record this In this known design, the plate is relatively thick in the area of the axis of rotation executed, which not only results in a high cost of building materials, but also in high flow resistance leads in the open position of the flap. With larger throttle valves one is already about Building material savings went over to making the middle part, which is in the area of the axis of rotation, hollow, but this does not remedy the disadvantage of a high flow resistance in the open position of the flap can.
Eine weitere bekannte Maßnahme besteht darin, den verhältnismäßig dick ausgeführten Teller zwischen den beiden Oberflächen mit einer oder mehreren Kanälen zu versehen, die in der öifnungslage der Klappe dem Strömungsmedium den Durchtritt gestatten. Der Teller einer solchen bekannten Drosselklappe besteht aus zwei kreisförmigen, im Abstand voneinander angeordneten Platten, die durch Zwischenwände untereinander verbunden sind, welche in der Öffnungslage der Klappe parallel zur Strömangsrichtung verlaufen. Wegen der verhältnismäßig großen, vom Strömungsmedium berührten Wandflächen ergibt sich aber auch hier ein beirächtlicher Strömungswiderstand für das zwischen den Platten durchtretende Medium. Überdies bedingt die zu den Drehzapfen exzentrische Lage der beiden Platten das Vorsehen eines kugeligen Gehäuses für die Klappe, dessen Innendurchmesser größer ist als der Innen-Another known measure consists in the relatively thick plate between the to provide both surfaces with one or more channels that are in the opening position of the flap Allow the flow medium to pass through. The plate of such a known throttle valve consists of two circular, spaced-apart plates, which are interconnected by partitions are connected, which in the open position of the flap run parallel to the direction of flow. Because of the relatively large, touched by the flow medium But here too there is a considerable flow resistance for the between the wall surfaces Medium passing through plates. In addition, the eccentric position of the two plates with respect to the pivot pin is necessary the provision of a spherical housing for the flap, the inner diameter of which is larger than the inner

Der Erfindung liegt die Aufgabe zugrunde, eine Verstärkung für den Teller einer Drosselklappe zu ermög liehen, welche Verstärkung einerseits bei kleinstemThe invention is based on the object of providing a reinforcement for the plate of a throttle valve borrowed what gain on the one hand at the smallest

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Teller als eine im wesentlichen in einer Ebene durch die Drehachse liegende Abschlußplatte ausgeführt und mit einer die Ansatzstellen der Drehzapfen verbindenden, sich über eine mittlere Zone des Tellers erstreckenden und ihn zu einem Fachwerkträger e.-gänzenden Verstrebung versehen ist, welche min-This object is achieved in that the plate as an essentially in one Executed plane through the axis of rotation lying end plate and with one of the attachment points of the pivot pin connecting, extending over a central zone of the plate and turning it into a truss e.-complementary bracing is provided, which min-

According to FIGS. 1 to 3, the throttle valve has a plate 1 and two opposing pivot pins 2. The plate 1 is designed as an end plate lying essentially in one plane through the axis of rotation and is provided with a strut, which consists of flat plates 3, 4, 5 and two Ribs 6, 7 consists. The ribs 6, 7 are perpendicular to the plate 1. They extend over the entire plate and together with the plate 1 and the plates 3, 4, 5 form a truss in the middle zone. The ribs 6, 7 and the plates 3, 4. 5 are parallel to the diameter of the plate 1, which is perpendicular to the axis of rotation, that is to say they run in the direction of flow when the flap is in the open position.
Die Platten 3, 4, 5 verbinden die Ansatzstellen der beiden Drehzapfen 2 am Teller 1 miteinander, und die über die mittlere Zone, d. h. über die Platten 3. 4, 5 hinausgehenden Teile der Rippen 6, 7 tragen die von der Achse entfernten Teile des Tellers 1.

Es können beispielsweise die Drehzapfen 2 aus Stahlguß bestehen und die den Fachwerkträger bildenden Teile 1, 3, 4, 5, 6, 7 aus Blechtafeln gefertigt sein,For example, the pivot pins 2 can be made of cast steel and form the truss Parts 1, 3, 4, 5, 6, 7 be made from sheet metal,

These parts are preferred designed with a streamlined cross-section in order to

Durch die beschriebene Bauart wird eine hohe Tragfähigkeit der Klappe erreicht, ohne daß aber in der Öffnungslage der Klappe der freie Durchflußquerschnitt wesentlich beeinträchtigt ist Die Bauhöhe des Fachwerkträgers ist nur durch die Bedingung beschränkt, daß die Klappe gedreht werden kann, d. h„ der Fachwerkträger muß innerhalb einer Kugel liegen, deren Mittelpunkt auf der Drehachse liegt und deren Durchmesser gleich dem Durchmesser des Klappentellers ist Da sich die Platten 3,4,5 der Verstrebung nur über die mittlere Zone des Tellers 1 erstrecken, ist der durch sie verursachte Strömungswiderstand gering.The design described has a high load-bearing capacity reaches the flap, but without the free flow cross-section in the open position of the flap is significantly impaired The height of the truss is only limited by the condition, that the flap can be rotated, d. h "the truss must lie within a sphere, the center of which is on the axis of rotation and its diameter is equal to the diameter of the valve plate Since the plates 3,4,5 of the strut only over the extend middle zone of the plate 1, the flow resistance caused by them is low.
Die F i g. 4 bis 6 zeigen andere Möglichkeiten für den Bau der Verstrebungen. Gemäß F i g.4 ist nur eine einzige senkrecht zur Drehachse stehende Rippe 6' mit die Ansatzstellen der Zapfen 2 verbindenden Platten 3' und V vorhanden. Gemäß F i g. 5 ist diese Verstrebung noch durch eine symmetrisch dazu auf der anderen Seite des Tellers 1 liegende Verstrebung mit einer Rippe 6" und zwei Platten 3", 5" ergänzt Gemäß F i g. 6 sind die Rippen 6,7 der F i g. 1 durch zwei schräg zur Drehachse stehende, von den Knoten zwischen den Platten 3. 4, 5 bis zur Mitte des Tellers 1 sich erstreckende Platten 11,12 ersetztThe F i g. 4 through 6 show other ways of building the bracing. According to F i g.4 there is only one perpendicular to the axis of rotation rib 6 'with the attachment points of the pin 2 connecting plates 3' and V present. According to FIG. 5 this bracing is also symmetrical to it on the other side of the plate 1 lying strut with a rib 6 ″ and two plates 3 ″, 5 ″ added according to FIG the ribs 6, 7 of FIG. 1 by two inclined to the axis of rotation, of the nodes between the plates 3. 4, 5 up to the middle of the plate 1 extending plates 11,12 replaced
