Description

Dampf-, Luft-, Gas- oder Flüssigkeitsmesser. Das Gerät besteht aus einem Gefäß, in dem sich ein Hohlkegel a befindet, in dem achsial beweglich ein Teller b geführt wird, oder aus einem Gefäß mit einer kreisrunden Öffnung, in der achsial beweglich ein Vollkegel geführt wird. Der Teller b oder der Vollkegel werden im folgenden Schwebekörper genannt.Steam, air, gas or liquid meters. The device consists of a vessel in which there is a hollow cone a, in which an axially movable one Plate b is guided, or from a vessel with a circular opening in which axially movable a full cone is guided. The plate b or the full cone will be hereinafter referred to as the float.

Der Schwebekörper wird so belastet, daß die Durchströmmenge entweder den Erhebungen des Schwebekörpers oder dem Druckunterschied zu beiden Seiten des Schwebekörpers proportional sind. Bei den bisher bekannt gewordenen Geräten dieser Art wird der Schwebekörper entweder durch Gewichte belastet oder durch eine Federkraft, :die proportional dem Hub. zunimmt. Als Maß für die Durchströmmenge wird dabei entweder 'die Erhebung des Schwebekörpers oder die Druckdifferenz zu beiden Seiten des Schwebekörpers benutzt. .Um dabei den Durchströmmengen proportionale Erhebungen des Schwebekörpers bzw. Druckzunahmen zu erhalten, müssen die Durchströmgefäße von geradlinigen Kegeln bedeutend ab ichend geformt werden, was in Bezug aufersiellung'und Justierung` kostspielig ist. Die durch Gewichte belasteten Schwebekörper haben außerdem den Nachteil der unstabilen Einstellung und bedürfen einer wirksamen Dämpfung. Beim Versagen der Dämpfungseinrichtung gerät der Schwebekörper mit dem Belastungsgewicht in Schwingungen und kann bei Eintritt von Resonanz die Rohrleitungen beschädigen. Die genannten Nachteile werden bei dem neuen Gerät vermieden. Die Unstabilität wird durch die mit der Erhebung des Schwebekörpers zunehmende Belastung beseitigt. Die Schwierigkeit der Herstellung der von Kegelformen abweichenden Gefäße wird dadurch beseitigt, daß die Zunahme der auf den Schwebekörper wirkenden Belastung so bemessen wird, daß die gewünschte Proportionalität der Erhebungen oder der Druckunterschiede erreicht wird, und zwar geschieht dies auf folgende Weise: Am unteren Ende der Schwebekörperachse ist eine Rolled angebracht. Diese wird von zwei Kurvenhebeln c umschlossen, welche ihrerseits durch die Feder e zusammengehalten werden. Durch geeignete Gestaltung der Kurvenhebel c kann die gewünschte Porportionalität leicht erzielt werden.The float is loaded so that the flow rate either the elevations of the float or the pressure difference on both sides of the Float are proportional. With the devices that have become known so far, this Type is the float either loaded by weights or by a spring force, : which is proportional to the stroke. increases. The measure for the flow rate is either '' the elevation of the float or the pressure difference on both sides of the float used. .To do this, elevations of the float proportional to the flow rate To obtain or increase in pressure, the flow-through vessels must be made of rectilinear cones significant starting to be shaped, what is related to Adjustment is expensive. The floats loaded by weights also have the disadvantage of the unstable setting and require effective damping. At the Failure of the damping device causes the float with the loading weight in vibrations and can damage the pipelines if resonance occurs. The disadvantages mentioned are avoided with the new device. The instability will eliminated by the increasing load with the elevation of the float. the Difficulty in the production of the vessels deviating from cone shapes is thereby eliminates the fact that the increase in the load acting on the float is so dimensioned that the desired proportionality of the elevations or the pressure differences is achieved, this is done in the following way: At the lower end of the float axis a rolled is attached. This is enclosed by two cam levers c, which in turn are held together by the spring e. By appropriate design the cam lever c, the desired proportionality can easily be achieved.
