Wassermenge.Amount of water.
Den Gegenstand vorliegender Erfindung bildet ein selbstregistrirender Apparat zum Messen der in Rohrleitungen flieisenden Wassermengen, bei dem diese Mengen aus der Durchnuisgeschwindigkeit und der Zeit bestimmt werden. Die Geschwindigkeit wird in bekannter Weise durch den Druckunterschied vor und hinter einem in die Leitung eingeschalteten Widerstandrohr gemessen. Dieser selbst wird beispielsweise durch die Ausbiegungen einer Membran gemessen, deren beide Seiten unter dem Druck vor und hinter dem Widerstandsrohr stehen.The subject of the present invention is a self-registering apparatus for Measuring the amount of water flowing in the pipelines at which these amounts are derived from the Can be determined by speed and time. The speed is in known way by the pressure difference upstream and downstream of a switched on in the line Resistance tube measured. This itself is, for example, caused by the bends a membrane measured, both sides of which under the pressure in front of and behind the Stand resistance tube.
Die Erfindung besteht in einer Einrichtung, durch welche die Ausweichungen der Membran in der Weise auf die Antriebsvorrichtung für das Zählrad übertragen werden, dafs das Zählrad immer mit einer der Durchfluisgeschwindigkeit des Wassers proportionalen Geschwindigkeit umläuft. Als Uebertragungsorgan dient eine Schnecke, welche der Ausweichung der Membran entsprechend gedreht wird und in deren Gewinde .das die Antriebsvorrichtung für das Zählwerk regelnde Organ eingreift. Die Gewindesteigung der Schnecke kann so berechnet werden, dafs sich die Antriebsvorrichtung immer in der Weise einstellt, dafs dem Zählrad eine der Durchflufsgeschwindigkeit des. Wassers proportionale Umdrehungsgeschwindigkeit ertheilt wird.The invention consists in a device by which the deflections of the membrane are transmitted in such a way to the drive device for the counting wheel that the counting wheel always with a speed proportional to the flow speed of the water running around. A screw serves as the transmission element, which is rotated according to the deflection of the membrane and in the thread .das engages the drive device for the counter regulating organ. The thread pitch of the worm can be calculated so that the drive device always adjusts in such a way that the counter wheel one of the flow rate of the water proportional speed of rotation is imparted.
Auf beiliegender Zeichnung ist der Erfindungsgegenstand zur Darstellung gebracht, und zwar zeigt Fig. 1 eine schematische Darstellung des Erfindungsgegenstandes, Fig. 2 die Anordnung des Widerstandsrohres, Fig. 3 ein Schema zur Festlegung der für · die Schnecke zu verwendenden Steigung, Fig. 4 die Schnecke in Ansicht, während Fig. 5 eine Ansicht der zur Registrirung der verbrauchten Wassermengen dienenden Vorrichtung darstellt. Fig. 6 veranschaulicht eine Ansicht des Registrirwerkes zur Festlegung des jeweiligen Wasserdruckes.The subject of the invention is shown on the accompanying drawing, namely, FIG. 1 shows a schematic representation of the subject matter of the invention, FIG. 2 the arrangement of the resistance tube, FIG. 3 a diagram for determining the for · the Screw pitch to be used, FIG. 4 shows the screw in a view, while FIG. 5 shows a Is a view of the device used to register the amount of water consumed. Fig. 6 illustrates a view of the registration mechanism for determining the respective Water pressure.
In dem Gehäuse 1 (Fig. 1 und 2) ist eine Membran 2 vorgesehen. Das Gehäuse 1 ist zu einem Rohr ausgebildet, welches in die Rohrleitung 3 in der aus Fig. 2 ersichtlichen Wreise eingeschaltet werden kann. Man nehme an, das Wasser trete, aus den Wasserwerken kommend, in Pfeilrichtung (Fig. 2) bei der Stelle 5 in die Leitung 3 ein, welche in bekannter Weise durch die Widerstände 4 eine Querschnittsverengung aufweist. Diese Querschnittsverengung hat den Zweck, dafs das Wasser durch die Leitung 3 nicht in voller Geschwindigkeit fliefsen kann, sondern auf die Membran 2, sofern es in der Pfeilrichtung fliefst, derart in ebenfalls bekannter Weise einwirkt, dafs diese Membran nach rechts je nach dem auftretenden Druck mehr oder weniger ausgebogen wird. Die Membran 2 ist mit einer Stange 6 (Fig. 1) verbunden, welcher eine der Gröise der Ausbiegung entsprechende Längsbewegung ertheilt wird. - An dem einen freien Ende dieser Stange ist dieselbe mit einer Verzahnung versehen, und diese Verzahnung greift in einen Trieb der Welle 7 ein. Die Welle 7 wird daher je nach der Gröise des Ausschlages der Membran 2 um einen geringeren oder gröfseren Winkel um ihre Achse gedreht. Die Bewe-A membrane 2 is provided in the housing 1 (FIGS. 1 and 2). The housing 1 is formed into a tube which r in the pipeline 3 in the manner shown in Fig. 2 W can be switched on ice. Assume that the water, coming from the waterworks, enters the line 3 in the direction of the arrow (FIG. 2) at point 5, which has a cross-sectional constriction due to the resistors 4 in a known manner. This cross-sectional narrowing has the purpose that the water cannot flow through the line 3 at full speed, but on the membrane 2, if it flows in the direction of the arrow, acts in such a known manner that this membrane moves to the right depending on the pressure occurring is bent more or less. The membrane 2 is connected to a rod 6 (FIG. 1) which is given a longitudinal movement corresponding to the size of the deflection. - At one free end of this rod the same is provided with a toothing, and this toothing engages in a drive of the shaft 7. The shaft 7 is therefore rotated around its axis by a smaller or larger angle, depending on the magnitude of the deflection of the membrane 2. The moving
