Description
Vorrichtung zum Regeln eines @tömes von schwankender Dichte Die vorliegende Erfindung betrifft eine weitere Ausbildung der Vorrichtung gemäß Patent 645 305 und bezweckt eine bequemere Handhabung der Vorrichtung des Hauptpatents.Apparatus for regulating a @tömes of fluctuating density The present The invention relates to a further embodiment of the device according to patent 645,305 and aims to make the device of the main patent more convenient to use.
Gegenstand des Hauptpatents ist eine Vorrichtung zur Regelung eines Gasstromes von schwankender Dichte für Heizwertbestimmungen, bei welcher die mit einem Druckregler und mit einem Strömungswiderstand versehene Hauptleitung sich in eine mit Düse versehene Ausgleichszweigleitung und in eine zum Kalorimeter führende Leitung gabelt und bei der die mit einer Düse versehene Hauptleitung in eine unter Atmosphärendruck stehende Kammer einmündet, von welcher die mit der Düse versehene Ausgleichsleitung und die keinerlei Strömungswiderstand aufweisende, zum Kalorimeter führende Meßleitung abzweigen.The main patent is a device for regulating a Gas flow of fluctuating density for calorific value determinations, in which the with a pressure regulator and a main line provided with a flow resistance into a compensating branch line provided with a nozzle and into one leading to the calorimeter Line forks and in which the main line provided with a nozzle into a sub Atmospheric pressure chamber opens, of which the one provided with the nozzle Compensating line and the one that does not have any flow resistance to the calorimeter Branch off the leading measuring line.
Die vorliegende Erfindung besteht darin, daß bei einer solchen Vorrichtung das Ausgleichsrohr durch ein teleskopartig aufgesetztes Rohr in seiner Länge einstellbar ist. Dadurch wird der Betrieb vereinfacht. Bei dem Kalorimeterbetrieb ergibt sich oft die Notwendigkeit einer Korrektur. Diese ist durch die Erfindung außerordentlich bequem; denn man kann von lNTeueinstellung des Nullpunktes des Thermometersystems absehen. Da sich das verlängerbare Rohr außerhalb des erwärmten Kalorimeterschrankes befindet, so ist man durch Veränderung der Rohrlänge in der Lage, innerhalb gewisser Grenzen Mehr- und Minderanzeigen des Kalorimeters von außen her ohne Störung des thermischen Gleichgewichtes zu korrigieren.The present invention resides in such a device the length of the compensating tube can be adjusted using a telescopic tube is. This simplifies the operation. With the calorimeter operation results often the need for correction. This is extraordinary due to the invention comfortable; because one can readjust the zero point of the thermometer system refrain. Because the extendable tube is outside the heated calorimeter cabinet is located, by changing the length of the pipe, one is able to move within a certain Limits over- and under-readings of the calorimeter from the outside without disturbing the correct thermal equilibrium.
Die Erfindung sei an Hand der Zeichnung beispielsweise erläutert.The invention will be explained with reference to the drawing, for example.
Das Gas fließt in der Hauptleitung i, wird durch den Druckregler a auf konstanten Druck gebracht und durch die Düse 3 auf Atmosphärendruck reduziert. Dann verzweigt sich das Rohr. Der Ausgleichszweig 6 hat ein teleskopartig aufgesetztes Rohr 16, das durch eine Blocki.erungsvorrichtung 17 gegen unbefugte Verschiebung gesichert ist. Das Kalorimeter ist schematisch durch das Blech 3 und Thermometer 9 angedeutet; letzteres ist durch die Kupplungsstange i i mit dem Kompensationsthermometer i o verbunden; 12 und 13 stellen eine übliche Anzeigevorrichtung dar. 15 stellt einen Absperrhahn dar, der jedoch nicht zum Gegenstand der vorliegenden Erfindung gehört.The gas flows in the main line i, is brought to constant pressure by the pressure regulator a and reduced to atmospheric pressure by the nozzle 3. Then the pipe branches. The compensation branch 6 has a telescopically attached tube 16 which is secured against unauthorized displacement by a blocking device 17. The calorimeter is indicated schematically by the sheet metal 3 and thermometer 9; the latter is connected to the compensation thermometer io by the coupling rod ii; 1, 2 and 13 illustrate a common display device. 15 represents a stopcock which, however, does not form part of the subject matter of the present invention.
