Abstract

The valve consists of parallel cylinder rollers (2,3) inside a housing (1). Each roller has a cavity enabling the valve to open and close when the cylinder rollers turn, when the cavity describes a circular passage.

Description

Die Erfindung betrifft ein Drosselventil das auf dem Prinzip des Hahnes basiert, welches zur Drosselung von Flüssigkeiten oder Gasen verwendet werden kann.The invention relates to a throttle valve based on the principle of the rooster, which for throttling liquids or gases can be used.

Bekannt sind Kugelhähne, die eine Querbohrung haben und durch eine viertel Umdrehung geschlossen, bzw. geöffnet werden können. Diese haben aber den Nachteil, daß schon beim geringen Öffnen des Ventils starke Wirbel entstehen können und somit das Ventil keine lineare Kennlinie aufweist. Der Erfindung liegt daher die Aufgabe zugrunde, ein Drosselventil zu entwickeln, das schon bei kleinen Öffnungswinkeln möglichst keine Wirbel entstehen läßt, und zugleich den Volumenstrom so wenig wie möglich umlenkt.Ball valves are known, the one Have cross hole and through a quarter Rotation closed or opened can be. But these have the Disadvantage that even with little opening strong swirls of the valve can arise and thus the valve is not a linear one Has characteristic. The invention lies hence the task of a To develop throttle valve that already at small opening angles if possible none Vortex creates, and at the same time the Volume flow as little as possible redirects.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß dieses Ventil aus parallelen Zylinderrollen besteht, welche in einem Gehäuse untergebracht sind. Jeder der beiden Rollen enthält eine Aussparung, wodurch das Ventil beim Verdrehen der Zylinderrollen öffnet bzw. schließt.This object is achieved according to the invention solved by this valve off parallel cylindrical rollers, which in are housed in a housing. Everyone the two rollers contain a recess, causing the valve to twist when Cylinder rollers open or close.

Als Material für die beiden Rollen werden vorzugsweise harte Werkstoffe verwendet, welche nur eine geringe plastische Verformung zulassen. Dies wird gefordert, da die Abdichtung des Ventils nur durch kleine Toleranzen und durch eine gewisse Vorspannung erreicht wird. Das Gehäuse wird zweckmäßig als Gußteil hergestellt, um eine kompakte Bauform des Ventils zu erreichen.As material for the two roles preferably hard materials are used, which is only a little plastic Allow deformation. This is required because the sealing of the valve only through small tolerances and by a certain Preload is reached. The housing is appropriately manufactured as a casting, to a compact design of the valve to reach.

Im folgenden wird ein Ausführungs­ beispiel der Erfindung anhand von Zeichnungen näher erläutert.The following is an execution example of the invention based on Drawings explained in more detail.

Es zeigen:Show it:

Fig. 1 eine Seitenansicht des Ventils. Fig. 1 is a side view of the valve.

Fig. 2 einen Schnitt durch das Ventil in der Höhe der Bohrung. Fig. 2 shows a section through the valve at the height of the bore.

Gemäß Fig. 1 befinden sich im Gehäuse 1 zwei Zylinder 2, 3. Diese zwei Zylinder haben an der oberen Seite einen kleineren Durchmesser, da dies das Abdichten dem Ventils erleichtert. Auf den kleineren Durchmessern befinden sich außerhalb des Ventils je ein Zahnrad 4, 5 mit dem gleichen Durchmesser der Zylinder. Die Verzahnung dient zur Kraftübertragung und zur Synchronisierung der beiden Zylinder. Über den Hebel 6 kann das Ventil in seine gewünschte Stellung gebracht werden. Die Abschlußplatte 7 ist lediglich zum Verschieben des Ventils und wird diesbezüglich mittels mehrerer Schrauben mit dem Gehäuse 1 verbunden. Das Ventil ist gemäß Fig. 1 und 2 im geöffneten Zustand dargestellt. Zum Verschließen reicht eine viertel Umdrehung des Hebels 6 aus.Referring to FIG. 1 are located in the housing 1, two cylinders 2, 3. These two cylinders have a smaller diameter on the upper side as this makes it easier to seal the valve. On the smaller diameters there are a gear 4 , 5 with the same diameter of the cylinders outside the valve. The teeth serve to transmit power and to synchronize the two cylinders. The valve can be brought into its desired position via the lever 6 . The end plate 7 is only for moving the valve and is connected to the housing 1 in this respect by means of several screws. The valve is shown in FIGS. 1 and 2 in the open state. A quarter turn of the lever 6 is sufficient for closing.

Die Durchlaßöffnung des Ventils muß nicht zwingend nur als Bohrung ausgeführt sein, sondern kann auch wie in Fig. 3 und 4 dargestellt, während des Verdrehens des Ventils immer einen kreisförmigen Durchlaß ermöglichen.The passage opening of the valve does not necessarily have to be designed as a bore, but can also, as shown in FIGS. 3 and 4, always allow a circular passage during the turning of the valve.

1. Drosselventil für flüssige oder gasförmige Medien ist dadurch gekennzeichnet, daß dieses Ventil aus parallelen Zylinderrollen besteht, welche in einem Gehäuse untergebracht sind. Jede Rolle enthält eine Aussparung, wodurch das Ventil beim Verdrehen der Zylinderrollen öffnet bzw. schließt.1. Throttle valve for liquid or gaseous media is characterized in that this valve consists of parallel cylindrical rollers, which are housed in a housing. Each roller contains a recess, whereby the valve opens or closes when the cylindrical rollers are turned. 2. Drosselventil für flüssige oder gasförmige Medien nach Anspruch 1, dadurch gekennzeichnet, daß die Aussparung beim Verdrehen des Ventils einen kreisförmigen Durchlaß beschreibt (Fig. 3 und 4).2. Throttle valve for liquid or gaseous media according to claim 1, characterized in that the recess describes a circular passage when turning the valve ( Fig. 3 and 4).
