Description
Flügelradwassermesser Die Erfindung bezieht sich auf Einstrahlwassermesser und bezweckt, einen solchen Messer den besonderen Ansprüchen, 'welche bei seiner Verwendung in Warmwasserheizungen an ihn gestellt werden, anzupassen.Impeller water meter The invention relates to single jet water meters and the purpose of such a knife is to meet the special needs of his Use in hot water heating systems can be put to him to adapt.
Die Erfindung ist im Anspruch gekennzeichnet und wird im folgenden an Hand der Abbildungen näher beschrieben.The invention is characterized in the claim and will be described below described in more detail using the illustrations.
Das Heißwasser tritt bei I in eine Düse, und nachdem es mäßig beschleunigt wurde tangential in das dahinterliegende bekannte Meßgerinne 2 ein, um durch den Austrittsstutzen 3 in den Heizkörper der Warmwasserheizung zu treten. Das Meßrad 4, welches mit seinen Flügeln 5 in das Gerinne 2 eintaucht, wird durch die Wasserströmung um seine Achse 6 in Drehung versetzt und überträgt diese Bewegung in beliebiger Weise auf ein besonderes Zählwerk, welches hierbei ohne Beachtung bleiben kann.The hot water enters a nozzle at I, and after it accelerates moderately was tangential into the well-known measuring channel 2 behind it, in order to pass through the Exit nozzle 3 to step into the radiator of the hot water heating. The measuring wheel 4, which dips with its wings 5 into the channel 2, is caused by the water flow about its axis 6 in rotation and transmits this movement in any Way on a special counter, which can be ignored here.
Die im zylindrischen Gehäuse auftretenden Wasserwirbel werden durch die Schützenwand 7 vernichtet. Soweit sie aber auf der dem Gerinne 2 entgegengesetzten Seite des runden Gehäuses durch die Rückseite der Flügel 5 hervorgerufen werden, sollen sie durch den Kanal 8 nach dem Austrittsstutzen ungehindert abfließen können, wobei die erhöhte Wassergeschwindigkeit im Gerinne :2 am Gerinneaustritt fördernd wirkt. Der Wiedereintritt in das Meßgerinne wird durch den beschleunigten Wasserstrahl der Eintrittsdüse verhindert. An der vorderen Kante der inneren Gerinnewand bildet sich ein kleiner Wasserwirbel, welcher für sich kreist und nach 8 ablenkt. Die Meßradflügel werden vorteilhaft, wie in Abb. 3 und 4 gezeigt ist, pfeilförmig in der Strom- bzw. Drehrichtung abgebogen, wodurch die Wasserverdrängung nach oben und unten auf der Flügelrückseite begünstigt wird.The water eddies occurring in the cylindrical housing are caused by the Schützenwand 7 destroyed. So far, however, on the opposite of the channel 2 Side of the round housing caused by the back of the wings 5, they should be able to flow unhindered through channel 8 after the outlet nozzle, where the increased water velocity in the channel: 2 promoting at the channel outlet works. The re-entry into the measuring flume is caused by the accelerated water jet the inlet nozzle prevented. Forms at the front edge of the inner channel wall a small water vortex, which circles by itself and deflects after 8. The measuring wheel wings are advantageous, as shown in Fig. 3 and 4, arrow-shaped in the current or Direction of rotation bent, causing the water displacement up and down on the Wing back is favored.
Durch vorstehend geschilderte Anordnung ist es möglich, mit einem Gesamtwiderstand des Messers von etwa 2o mm Wassersäule auszukommen, was bei den üblichen Warmwasserumlaufheizungen mit Temperaturgefälle Voraussetzung ist, um die Meßgenauigkeit innerhalb der zulässigen Fehlergrenzen zu halten.By the arrangement described above, it is possible with a Total resistance of the knife of about 2o mm water column, which is what the usual hot water circulation heating systems with temperature gradient is a prerequisite for the To keep the measurement accuracy within the permissible error limits.
