Einstellvorrichtungen für Flügelradmesser, bei welchen die Umdrehungsgeschwindigkeit des Mefsrades mit Hülfe eines Gegenstromes regulirt werden kann, sind zwar seit langer Zeit bekannt, doch haben die bekannten Einstellvorrichtungen dieser Art den Uebelstand, dafs durch die Verstärkung oder Schwächung des Regulirstromes zu gleicher Zeit die Querschnittssumme der Einlafskanäle und damit die Durchlafsfähigkeit des Wassers verändert wird. Die vorliegende Erfindung bezieht sich nun auf eine Einstellvorrichtung, welche, obwohl auch bei ihr das Princip eines regulirbaren Gegenstromes Anwendung findet, frei ist von dem genannten Uebelstande. Dieses Resultat wird durch Anwendung einer Ringschütze erzielt, welche den Querschnitt je eines Gegenstrom- und eines Gleichstromkanals gleichzeitig um denselben Betrag, aber im entgegengesetzten Sinne zu ändern gestattet.Adjustment devices for vane knives, in which the speed of rotation of the Mefsrades can be regulated with the aid of a countercurrent, have been for a long time known, but the known adjusting devices of this type have the disadvantage that Through the strengthening or weakening of the regulating flow at the same time, the total cross-section of the inlet ducts and thus the permeability of the water is changed. The present invention now relates to an adjusting device which, although also with it the principle of an adjustable countercurrent Is used, is free from the aforementioned drawback. This result is achieved by using a ring shooter, which the cross-section of a countercurrent and a cocurrent channel at the same time the same amount, but allowed to change in the opposite sense.
Die Flüssigkeit tritt wie bei allen Messern zuerst in das Gehäuse und dann in die Kanäle a bezw. b im Einsatz (Fig. 1 und 2). Geht der Messer zu schnell, so wird die Ringschütze d etwas gedreht, so dafs sie die zwei Regulirungsgleichstromkanäle α je nach Bedürfnifs mehr oder weniger schliefst und gleichzeitig die zwei Gegenstromkanäle b in demselben Mafse öffnet. Geht der Messer zu langsam, so findet das Umgekehrte statt. Man öffnet dann die Gleichstromkanäle und schliefst gleichzeitig die Gegenstromkanäle ebensoviel ab. Auf diese Weise wird der Flüssigkeit immer der gleiche Querschnitt zum Durchfliefsen gelassen. Es wird also beispielsweise ein 10 mm-Messer trotz Regulirung auch ein Flüssigkeitsquantum geben, welches einem Querschnitt von 10 mm Durchmesser entspricht.As with all knives, the liquid first enters the housing and then into the channels a or. b in use (Fig. 1 and 2). If the knife goes too fast, the ring gate d is turned a little so that it closes the two regulating direct flow channels α more or less, depending on the need, and at the same time opens the two counter flow channels b to the same extent. If the knife goes too slowly, the reverse happens. The cocurrent channels are then opened and at the same time the countercurrent channels are closed off as much. In this way, the liquid is always left the same cross-section to flow through. Thus, for example, a 10 mm knife will also have a liquid quantum in spite of regulation, which corresponds to a cross section of 10 mm diameter.
