Description

Regulierorgan für solche Flügelradflüssigkeitsmesser mit Vor- und Rückwärtslauf, deren Einlauf- und Auslaufkanäle in verschiedenen -horizontalen Ebenen liegen, mit einem einzigen, ständig von der Flüssigkeit umspülten, oberhalb beider Kanalreihen-eingebauten Stauorgan, das von außen einstellbar ist Bei Mehrstrahlflügelradflüssigkeitsmessern sind zur genauen Justierung des Messers Reguliervorrichtungen bekanntgeworden, welche ein z. B. balkenförmiges, von außen @einstellbares Stauorgan enthalten, das oberhalb des Flügelrades angeordnet ist und von der durch den Messer strömenden Flüssigkeit umspült wird.Regulating element for such impeller liquid meters with fore and Reverse run, its inlet and outlet channels in different horizontal planes lie, with a single one, constantly bathed by the liquid, above both Damming element built in rows of channels, which can be adjusted from the outside regulating devices have become known for precise adjustment of the knife, which a z. B. contain bar-shaped, from the outside @adjustable dam that is above of the impeller and of the liquid flowing through the knife is washed around.

Bei solchen Flügelradmessern, die für Vor-und Rückwärtsantrieb des Meßwerkes ausgebildet sind, bestehe. nun bisher insofern. Schwierigkeiten; -als eine Verstellung des Stauorgans wegen der unsymmetrischen Anordnung des Regulierbalkens zu den beiden Kanalreihen sich für den Vor- und Rückwärtslauf des Messers unterschiedlich auswirkt. Dies hat zur Folge, daß der ausnutzbare Regulierbereich verhältnismäßig gering' ist und außerdem auch die Regulierkurven, d. h. die Flügeldrehzahlen, bei konstanter Strömung in Abhängigkeit von der Stellung des Stauorgans nicht günstig verlaufen.With such impeller knives, which are used for the forward and backward drive of the Measuring mechanism are formed, exist. so far so far. Trouble; -as an adjustment of the storage element because of the asymmetrical arrangement of the regulating bar for the two rows of channels are different for the forward and backward movement of the knife affects. This has the consequence that the usable regulating area is proportionate low 'and also the regulation curves, i. H. the blade speeds, at constant flow depending on the position of the dam is not favorable get lost.

Gemäß der Erfindung werden diese Mängel dadurch vermieden, daß das Stauorgan aus zwei mit je einer ebenen und einer gekrümmten Staufläche und dazwischenliegenden scharfen Trennkanten versehenen Hälften besteht, die derart gegeneinander versetzt angeordnet sind, daß bei Rückwärtslauf die beiden gekrümmten Fläche. von der am nächsten liegenden Kanalreihe und bei Vorwärtslauf die beiden ebenen Flächen von der weiter entfernt liegenden Kanalreihe beaufschlagt werden. Es sind also die gekrümmten Flächen derjenigen Einströmöffnungen zugeordnet, welche dem Stauorgan am nächsten liegen, wodurch die Stauwirkung vermindert wird.According to the invention, these deficiencies are avoided in that the storage element consists of two halves, each provided with a flat and a curved storage surface and sharp separating edges in between, which are offset from one another in such a way that the two curved surfaces are reversed. from the next row of channels and, when running forwards, the two flat surfaces from the row of channels further away are acted upon. The curved surfaces of those inflow openings are therefore assigned which are closest to the damming element, as a result of which the damming effect is reduced.

Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

Fig. i zeigt einen Mehratrablfiügelradmesser, teilweise im Schnitt, mit dem bisher üblichen Stauorgan von rechteckigem Querschnitt, während in. Fig. 2 in vergrößertem -Maßstabe das bei diesem Messer erfindungsgemäß vorgesehene Stauorgan perspektivisch dargestellt ist.Fig. I shows a Mehratrablfiügelradmesser, partially in section, with the previously usual stowage member of rectangular cross-section, while in. Fig. 2 shows, on an enlarged scale, the stowage element provided in accordance with the invention for this knife is shown in perspective.

Der mit den beiden AnschIußstützen i und z ausgerüstete Messer enthält einen Grundbecher 3, in welchem das Flügelrad ¢ angeordnet ist. An der Seitenwandung des Grundbechers sind zwei Gruppen von Öffnungen 5 und 6 vorgesehen, von denen bei Vorwärtslauf die Öffnungen 5 als Einströmöffnungen und die Öffnungen 6 als Ausströmöffnungen dienen, während bei Rückwärtslauf die Flüssigkeit durch die Öffnungen 6 eintritt und durch die Öffnungen 5 austritt. Unterhalb des Flügelrades ist eine Anzahl von feststehenden Staurippen 7 vorgesehen. Oberhalb des Flü= gehades befindet sich :ein Stauorgan 8, das" in nicht näher gezeichneter Weise von außen her mittels eines Schlüssels zur Regulierung drehbar ist. In dem Gehäusekopf 9 befindet sich in bekannter Weise das von dem Flügelrad q. angetriebene Zeigerwerk.The knife equipped with the two connection supports i and z contains a basic cup 3 in which the impeller ¢ is arranged. On the side wall of the basic cup are two groups of openings 5 and 6 provided, of which the openings 5 as inflow openings and the openings when running forward 6 serve as outflow openings, while the liquid flows through when running backwards the openings 6 enters and exits through the openings 5. Below the impeller a number of stationary storage ribs 7 is provided. Above the wing is: a stowage member 8, which "in a manner not shown in detail from the outside can be rotated by means of a key for regulation. Located in the housing head 9 in a known manner that of the impeller q. driven hand movement.

Gemäß der Erfindung sind nun die beiden wirksamen Oberflächen des Stauorgans 8 unter sich verschieden geformt, wie dies aus Fig. 2 näher ersichtlich ist. Das hier dargestellte Stauorgan wird auf den bei Rückwärtsgang beaufschlagten Seiten von -,einer etwa zylindrisch gekrümmten Fläche begrenzt, während die anderen Flächen eben ausgebildet sind. Bei Rückwärtslauf, wobei die Flüssigkeit durch die Öffnungen 6 ein- und durch die Öffnungen 5 austritt, trifft sie in Richtung der Pfeile io (Fig. 2) ,auf die gekrümmten Oberflächen des Stauorgans -8, während sie bei Vorwärtslauf durch die Öffnungen 5 eintritt und in Richtung der Pfeile i i auf die ebenen Begrenzungsflächen des Stauorgans 8 trifft.According to the invention, the two effective surfaces of the Stowage organ 8 is shaped differently among themselves, as can be seen in more detail in FIG is. The storage element shown here is acted upon in reverse gear Sides bounded by -, an approximately cylindrically curved surface, while the other Surfaces are flat. When running backwards, the liquid through the Openings 6 enters and exits through the openings 5, it meets in the direction of Arrows io (Fig. 2), on the curved surfaces of the dam -8, while they Enters through the openings 5 when running forward and in the direction of the arrows i i meets the flat boundary surfaces of the dam 8.

Wird der Messer für Vorwärtslauf verwendet, so sind im wesentlichen die beiden ebet nen Flächen des Stauorgans 8 (Fig. 2) wirksam, während beim Rückwärtslauf die gerundeten Flächen des Stauorgans in der Hauptsache die Regulierwirkung ausüben. Es hat sieh gezeigt, daß man in dem dargestellten Ausführungsbeispiel den bei Vor-und Rückwärtslauf ausnutzbaren Regulierbereich auf das. Doppelte vergrößern kann gegenüber der bisher üblichen Anwendung eines Stauorgans reit rechteckigem Querschnitt, und daß außerdem die Regulierkurve für Vorwärtslauf in diesem Falle insofern erheblich günstiger verläuft, als sie sich der Form einer Geraden erheblich mehr nähert. Dabei wirken bei Vorwärtslauf die an der Berührungsstelle der ebenen und der gekrümmten Fläche des Stauorgans liegenden scharfen Kanten (Fig. 2) nach den Versuchen ebenfalls recht günstig. .If the knife is used for forward rotation, then essentially the two surfaces of the dam 8 (Fig. 2) are effective while running backwards the rounded surfaces of the dam mainly exert the regulating effect. It has been shown that in the illustrated embodiment, the in front and Reverse usable regulation range to double. Can enlarge compared to the previously common use of a dam with a rectangular cross-section, and that also the regulating curve for forward running in this case is considerable runs more favorably than it approaches the shape of a straight line considerably more. Included When moving forward, those at the point of contact between the flat and the curved act Sharp edges lying on the surface of the dam (Fig. 2) after the experiments as well quite cheap. .
