Description

Reguliervorrichtung für Mehrstrahl-Flügelradwassermesser Die Erfindung bezieht sich auf eine Reguliervorrichtung an den bekannten Mehrstrahl-Flügelradwassermessern, bei denen das Flügelrad in einem zylindrischen Becher angeordnet ist, der horizontale, unter einem bestimmten Winkel zum Radius verlaufende Einlaßkanäle und ebensolche darüberliegende, aber entgegengesetzt gerichtete Auslaßkanäle hat. Bei solchen Messern ist bereits eine von außen zu bedienende Reguliervorrichtung bekannt, die aus einem in der Wand des Bechers angeordneten Kanal mit einstellbarem Querschnitt besteht, der in den ringförmigen Austrittsraum des Messers mündet. Bei dieser Anordnung ist die Regulierwirkung verhältnismäßig schwach. Sie wird erfindungsgemäß dadurch wesentlich verstärkt, daß der mit dem Regelorgan versehene Kanal unmittelbar in einen der Auslaßkanäle des Bechers mündet.Regulating device for multi-jet impeller water meters The invention relates to a regulating device on the known multi-jet impeller water meters, in which the impeller is arranged in a cylindrical cup, the horizontal, Inlet channels extending at a certain angle to the radius and the like has overlying, but oppositely directed outlet channels. With knives like that an externally operated regulating device is already known, which consists of a there is a channel with an adjustable cross-section arranged in the wall of the cup, which opens into the annular outlet space of the knife. With this arrangement the regulating effect is relatively weak. This makes it essential according to the invention reinforced that the channel provided with the control element directly into one of the outlet channels of the cup opens.

In der Zeichnung ist die Erfindung dargestellt.The invention is shown in the drawing.

Abb. i zeigt den Aufriß des Messers teilweise im Schnitt in seiner senkrechten Mittelebene. Abb.2 zeigt die Draufsicht teilweise im Schnitt, wobei dieser in der Höhe der Auslaßkanäle des Bechers geführt ist.Fig. I shows the front view of the knife partially in section in its vertical median plane. Fig.2 shows the top view partially in section, wherein this is guided at the level of the outlet channels of the cup.

Das zu messende Wasser tritt bei a durch ein Sieb in den Wassermesser ein. Der größte Teil fließt durch die Einlaßkanäle b in den Meßraum c, versetzt das Flügelrad d in Drehung, um durch die Auslaßkanäle e den Meßrauin und den Wassermesser wieder zu verlassen.The water to be measured enters the water meter at a through a sieve a. The largest part flows through the inlet channels b into the measuring space c, offset the impeller d in rotation to through the outlet channels e the measuring area and the water meter to leave again.

Ein kleiner Teil des bei ca eintretenden Wassers fließt durch den besonders angeordneten Kanal f unmittelbar in einen Auslaßkanal des Bechers. Das Regulierküken g ist so angeordnet, daß der Querschnitt des Kanals f durch einfache Drehung des Regulierkükens von o bis zu einem Größtwert verändert werden kann. Das durch den Kanal f strömende Wasser wirkt bei voller Belastung entgegen der Drehrichtung des Flügelrades, also bremsend. Bei ganz geringen Durchflußmengen kommt hingegen eine Wirkung des durch den Kanal f fließenden Wassers nicht mehr zur Geltung.A small part of the water entering at approx. Flows through the specially arranged channel f directly into an outlet channel of the cup. That Regulierküken g is arranged so that the cross section of the channel f by simple Rotation of the regulating plug can be changed from o to a maximum value. That Water flowing through channel f acts against the direction of rotation when fully loaded of the impeller, i.e. braking. On the other hand, at very low flow rates an effect of the water flowing through the channel f is no longer effective.
