Description

Selbsttätige Druckberücksichtigung bei Mengenmessern für strömende Medien. Die Erfindung betrifft eine bekannte Vorrichtung zur Berücksichtigung des Druckes bei Mengenmessern für strömende Medien. Hierbei wird der Drehpunkt des Schreibhebels, der an einem Kurbelarm der entsprechend dem Augenblickswert der strömenden Menge verdrehten Achse angelenkt ist, jeweils entsprechend dem Drucke verstellt. Das Neue besteht in der nachstehend beschriebenen und im Anspruch gekennzeichneten Konstruktion.Automatic pressure consideration with flow meters for flowing Media. The invention relates to a known device for taking into account the Pressure in flow meters for flowing media. The fulcrum of the writing lever is the one on a crank arm corresponding to the instantaneous value of the flowing amount twisted axis is hinged, each adjusted according to the pressure. The new consists in the construction described below and characterized in the claim.

Abb. i zeigt die neue Anordnung von der Seite und Abb. 2 den Grundriß. Das Kupferrohr i7 wird mit dem Gehäuse des Messers, z. B. eines Dampfmessers, verbunden, so daß der volle Druck aus dem Gehäuse des Meßapparates in die Bourdon-Manometerfeder i treten kann. Entsprechend dem verschieden starken Druck hebt oder senkt sich der Drehpunkt der daran angelenkten Zugstange 2, und entsprechend wird der Hebel 3 und damit dessen zwischen Spitzen lagernde Welle 15 verdreht. Auf der Welle 15 sitzt ein Hebel q., welcher durch die Stellschraube 16 fest auf der Welle 15 befestigt ist. Am Endpunkte des Hebels 4 befindet sich eine Rolle 6, gegen «-elche der Schreibhebel ? durch die- Feder 13 kraftschlüssig angedrückt wird.Fig. I shows the new arrangement from the side and Fig. 2 the plan. The copper pipe i7 is connected to the housing of the knife, e.g. B. a steam meter, connected, so that the full pressure from the housing of the measuring apparatus into the Bourdon manometer spring i can kick. The rises or falls according to the different levels of pressure The pivot point of the tie rod 2 hinged to it, and accordingly the lever 3 and so that the shaft 15, which is superimposed between the tips, is rotated. Sitting on shaft 15 a lever q. which is fixedly attached to the shaft 15 by the adjusting screw 16 is. At the end of the lever 4 there is a roller 6, against which the writing lever ? is pressed by the spring 13 force-fit.

Der GuBteller 8 ist vermittels einer Mutter io mit dem Meßapparat starr verbunden, die Welle 12 verdreht sich entsprechend dem Verbrauch. Auf der Welle 12 sitzt der Hebel i i, welcher entsprechend den Mengen, welche durch den Meßapparat hindurchfließen, Ausschläge macht. Der Schreibhebel 7 ist auf dem Hebel i i im Drehpunkte 14 gelagert. Der Hebel ? besitzt eine Kurve, welche einen Teil eines Kreises darstellt, mit dem Radius des Hebels-.. -@ Findet kein Verbrauch statt, so steht der Schreibstift des Hebels 7 in der Nullstellung. Die Veränderung des Druckes bleibt aber hierbei in an sich bekannter Weise unwirksam, weil die Kurve des Schreibhebels 7 der Teil eines Kreisbogens um die Achse 15 ist. Dagegen verstellt sich der Drehpunkt des Schreibhebels 7 bei auftretendem Verbrauch entsprechend dem jeweiligen Druck in ebenfalls an sich bekannter Weise. Ein besonderer Vorteil der neuen Konstruktion liegt darin, daß infolge der kraftschlüssigen Verbindung des Schreibhebels 7 mit dem Hebel :1 der sonst bei Kulissenführung mögliche tote Gang vermieden wird. Außerdem wird durch die Verwendung der Bourdon-Feder die Konstruktion verhältnismäßig einfach.The GuBteller 8 is rigidly connected to the measuring apparatus by means of a nut 10, the shaft 12 rotates according to the consumption. The lever ii sits on the shaft 12 and makes deflections according to the quantities flowing through the measuring apparatus. The writing lever 7 is mounted on the lever ii in the pivot point 14. The lever ? has a curve which represents part of a circle with the radius of the lever- .. - @ If there is no consumption, the pen of the lever 7 is in the zero position. The change in pressure remains ineffective in a manner known per se because the curve of the writing lever 7 is part of an arc around the axis 15 . On the other hand, the pivot point of the writing lever 7 is adjusted in a manner which is also known per se when consumption occurs in accordance with the respective pressure. A particular advantage of the new design is that due to the force-locking connection of the writing lever 7 with the lever: 1, the dead gear otherwise possible with link guidance is avoided. In addition, the use of the Bourdon spring makes the construction relatively simple.
