Description
Dampfmesser mit einem im Druckraum angeordneten, schwingenden Hohlkörper. Die Erfahrung zeigt, daß bei Meßgeräten nach Patent 3o995% die Gumrniverbindüügen ;:wischen dem Druckgefäß d und dem Quecksilberhohlkörper e unter dem Einfluß des c_?uecksilbers mit der Zeit undicht werden und dadurch kleine Abweichungen in der Anzeige erfolgen, welche zu beseitigen vorliegende Erfindung bezweckt.Steam meter with a vibrating hollow body arranged in the pressure chamber. Experience shows that rubber connections are used in measuring instruments according to patent 3o995% ;: wipe the pressure vessel d and the hollow mercury body e under the influence of the c_? uecksilbers will leak over time and thus small deviations in the Indication takes place, which the present invention aims to eliminate.
Dieselbe besteht zunächst darin, daß die Verbindung zwischen dem Druckgefäß d und dem Hohlkörper e durch ein Überlaufrohr a, das als Heber wirkt, dargestellt wird (Abb. i). Bei Beginn des Betriebes befindet sich in dein über dem Quecksilberspiegel von d befindlichen Teil des Überlaufrohres Luft oder Wasser. Üffnet man zunächst die Druckleitung b, die von der Überdruckseite der Drosselscheibe kommt, so gelangt der Druck vom Druckbehälter f auf das Quecksilber des offenen Gefäßes d. Infolge des Dru.ckunterschienes in d und c wird das Quecksilber durch das Rohr a nach dem Hohlkörper e gedrückt und dadurch eine dauernde Verbindung zwischen d und e hergestellt. Nun öffnet man die zweite von der Niederdruckseite der Drosselscheibe kommende Leitung c. Damfit nun der Hohlkörper sich abwärts bewegen kann, ist an das Druckgefäß d ein Rohr g angesetzt, das an seinem unteren Ende geschlossen ist, und in welches das Überlaufrohr a je nach der Stellung des Hohlkörpers e mehr oder weniger tief hineintaucht. Nun bewegt sich letzterer aber auch gegen die Leitung c; deshalb ist in bekannter Weise ein teleskopartig verschiebbares Rohrsystem mit Quecksilberdichtung .zwischen c und e eingeschaltet, an dessen Stelle-auch (Abb. a) eine Gummiverbindung lt mcglich ist, die nicht mit dem Quecksilber in Berührung kommt und daher keinen störenden Einfuß auf die Anzeige haben kann. Abb. 3 zeigt einen Hohlkörper mit zwei Ausgleichrohren a zum Zwecke des Gewichtsausgleichs, die dann in zwei Gefäße d oder ein ringförmiges Gefäß d tauchen können.This consists first of all in that the connection between the pressure vessel d and the hollow body e is represented by an overflow pipe a, which acts as a lifter (Fig. I). At the beginning of the operation there is air or water in the part of the overflow pipe above the mercury level of d. If you first open the pressure line b, which comes from the overpressure side of the throttle disc, the pressure from the pressure vessel f reaches the mercury in the open vessel d. As a result of the lower pressure rail in d and c, the mercury is pressed through the tube a to the hollow body e, thereby creating a permanent connection between d and e. Now open the second line c coming from the low pressure side of the throttle disc. If the hollow body can now move downwards, a pipe g is attached to the pressure vessel d, which is closed at its lower end and into which the overflow pipe a dips more or less deeply depending on the position of the hollow body e. But now the latter also moves against line c; Therefore, a telescopically displaceable pipe system with a mercury seal is inserted between c and e in a known manner, in the place of which a rubber connection is also possible (Fig. a), which does not come into contact with the mercury and therefore does not interfere with the display may have. Fig. 3 shows a hollow body with two compensation tubes a for the purpose of weight compensation, which can then dip into two vessels d or an annular vessel d.
