PATENTAMIPATENTAMI

Bei Meßgeräten nach Art des Dampfmessers nach Patent 193151 mit auf der einen Seite drehbar gelagertem und auf der anderen Seite federnd aufgehängtem Hohlkörper, der sich unter dem Einfluß des wechselnden Druckunterschiedes zu beiden Seiten einer Drosselstelle in der Dampfleitung aus einem Quecksilberdruckraum mehr oder weniger mit Quecksilber füllt, ist die Verbindung zwischen dem Quecksilberdruckraum und dem schwingenden Hohlkörper schwierig und teuer, da die Dichtungen im Drehpunkt der Leitungsspannung ausgesetzt sind, wodurch immerhin etwas Reibung entsteht.· Um letzteres zu vermeiden und die Herstellung der Meßgeräte zu erleichtern und zu verbilligen, soll der schwingende Körper e auch in einem Druckraum angeordnet werden, dessen Druckunterschied gegenüber dem Druck im Quecksilberraum nur gleich dem Spannungsunterschied vor und hinter der Drosselstelle in der Leitung ist.In measuring devices like the steam meter according to Patent 193151 with a hollow body rotatably mounted on one side and resiliently suspended on the other side, which fills more or less with mercury under the influence of the changing pressure difference on both sides of a throttle point in the steam line from a mercury pressure chamber , the connection between the mercury pressure chamber and the vibrating hollow body is difficult and expensive, since the seals are exposed to the line tension at the pivot point, which at least creates some friction Body e can also be arranged in a pressure space whose pressure difference compared to the pressure in the mercury space is only equal to the voltage difference upstream and downstream of the throttle point in the line.

Die Zeichnung zeigt ein schematisches Ausfühiungsbeispiel. Vor und hinter der Drosselstelle α der Hauptdampfleitung gehen mit Wasser gefüllte Rohre b und c zu dem Quecksilberdruckraum d und dem schwingenden Hohlkörper e ab; d und e liegen in einem Druckbehälter f; e und d sind durch ein leicht bewegliches Rohr, Schlauch o. dgl. verbunden, in welchem nur ein sehr geringer Druckunterschied gegen das Innere von f herrscht, so daß die Dichtung soviel wie gar nicht beansprucht wird. Das Quecksilber verschiebt sich unter dem Einfluß des Dampfstromes zwischen d und β in bekannter Weise.The drawing shows a schematic Ausfühiungsbeispiel. Before and after the throttle point α of the main steam line, pipes b and c filled with water go to the mercury pressure chamber d and the vibrating hollow body e ; d and e are in a pressure vessel f; e and d are connected by an easily movable pipe, hose or the like, in which there is only a very small pressure difference against the interior of f , so that the seal is hardly stressed at all. The mercury shifts under the influence of the steam flow between d and β in a known manner.

Über e wird ein Ansatz h angeordnet, welcher die Feder g aufnimmt und mit öl gefüllt ist, um ein Verrosten der Feder zu verhüten ; das Innere des Hohlkörpers β ist mit dem Räume f verbunden, da ersterer oben offen-ist.An approach h is arranged over e , which takes up the spring g and is filled with oil in order to prevent the spring from rusting; the interior of the hollow body β is connected to the space f , since the former is open at the top.

Patent-Ansprüche:Patent Claims: 1. Dampfmesser mit einem an einer Feder hängenden Hohlkörper, der sich in Abhängigkeit von der Druckdifferenz zu beiden Seiten einer Drosselstelle in der Dampfleitung aus einem Quecksilberdruckraum mehr oder weniger mit Quecksilber füllt, gekennzeichnet durch die Anordnung des schwingenden Quecksilberhohlkörpers (e) in einem Raum (f), welcher unter dem Druck in der Dampfleitung steht, um einen geringen Spannungsunterschied zwischen dem vom Raum (f) getrennt angeordneten Quecksilberdruckraum (d) und dem mit letzterem durch eine Leitung verbundenen Hohlkörper (e) zu erhalten, die Dichtung zwischen beiden zu erleichtern und somit unnötige Reibung zu verhindern und die Herstellung zu vereinfachen.1. Steam meter with a hollow body hanging from a spring, which fills more or less with mercury depending on the pressure difference on both sides of a throttle point in the steam line from a mercury pressure chamber, characterized by the arrangement of the vibrating hollow mercury body (e) in a room ( f), which is under the pressure in the steam line in order to obtain a small voltage difference between the mercury pressure chamber (d) , which is arranged separately from the space (f ) and the hollow body (e) connected to the latter by a line, to facilitate the seal between the two and thus to prevent unnecessary friction and to simplify manufacture. 2. Bei Meßgeräten nach Anspruch 1 die Anordnung einer Belastungsfeder (g) in einem, mit öl gefüllten Teiie (A) des Druckbehälters (f). 2. In measuring devices according to claim 1, the arrangement of a loading spring (g) in an oil-filled part (A) of the pressure vessel (f). Hierzu 1 Blatt Zeichnungen.1 sheet of drawings.
