Description
Meßvorrichtung für feuergefährliche Flüssigkeiten Die Erfindung betrifft eine vereinfachte und verbesserte Bauart der Meßvorrichtung für feuergefährliche Flüssigkeiten nach Patent 4811r2, durch die das zum zeitweisen Abschluß der Mündung der Luftausgleichleitung dienende Abschlußorgan (Schwimmerventil) in Fortfall kommt.Measuring device for flammable liquids The invention relates to a simplified and improved type of measuring device for flammable Liquids according to patent 4811r2, by which the temporary closure of the mouth the closing element (float valve) serving the air equalization line is no longer available.
Auf der Zeichnung ist der obere Teil eines nach der Erfindung gebauten Meßgefäßes der verbesserten Meßvorrichtung in senkrechtem Schnitt dargestellt.In the drawing is the upper part of one built according to the invention Measuring vessel of the improved measuring device shown in vertical section.
Das in den Deckel 16 des Meßgefäßes mündende Luftausgleichrohr 17 ist mit einem verlängerten Teil 3o versehen, der nach der Erfindung in den oberen Teil des beispielsweise oben trichterförmig erweiterten Überlaufrohres 9 derart hineinragt, daß zwischen beiden Rohren ein enger Ringspalt 31 verbleibt. Nach der Füllung des Meßgefä.ßes wird die Flüssigkeit mit großer Geschwindigkeit durch den nach Art eines Strahlsaugers wirkenden Ringspalt 31 zwischen den beiden Rohren 9, 3o gepreßt, wobei sie aus der Leitung 17 Luft ansaugt. Infolgedessen kann keine Flüssigkeit in die Leitung 17 emporsteigen, trotzdem deren Mündung 18 nicht mit einem Schwimmerventil o. dgl. zusammenwirkt.The air equalization tube 17 opening into the cover 16 of the measuring vessel is provided with an extended part 3o, which according to the invention in the upper Part of the overflow pipe 9, which is expanded in the shape of a funnel above, for example protrudes so that a narrow annular gap 31 remains between the two tubes. After When the measuring vessel is filled, the liquid moves through the Annular gap 31 acting like a jet suction device between the two tubes 9, 3o pressed, sucking air from the line 17. As a result, no Liquid rise up into the line 17, despite the fact that its mouth 18 is not with it a float valve or the like. Cooperates.
Oberhalb der Überlaufkante 24 des Überlaufrohres 9 sind in dem verlängerten Teil 3o des Luftausgleichrohres 17 eine oder mehrere enge Öffnungen 32 vorgesehen, die dazu dienen, das Entleeren des oberhalb der Überlaufkante 2¢ liegenden Halsraumes des Meßgefäßes nach Aufhören des Pumpens möglichst zu beschleunigen. Sobald die Flüssigkeit über der Überlaufkante 24 durch den Ringspalt 31 absinkt, dringt durch die Öffnung 32 Luft aus dem Luftausgleichrohr 17 ein, wodurch das Ablaufen der in dem Halsraum des Meßgefäßes befindlichen Flüssigkeit in das Überlaufrohr 9 beschleunigt wird. Die durch die Öffnung 32 im Augenblick der Vollfüllung des Meßgefäßes in das Rohrstück 30 eintretenden geringen Flüssigkeitsmengen werden durch den aus der Leitung 17 angesaugten Luftstrom in das Überlaufrohr 9 abgeführt, beeinträchtigen also die Wirkungsweise der Meßvorrichtung in keiner Weise.Above the overflow edge 24 of the overflow pipe 9, one or more narrow openings 32 are provided in the extended part 3o of the air equalization pipe 17, which serve to accelerate the emptying of the neck of the measuring vessel above the overflow edge 2 ¢ as possible after the pumping has stopped. As soon as the liquid sinks over the overflow edge 24 through the annular gap 31, air penetrates through the opening 32 from the air equalization tube 17, whereby the drainage of the liquid in the neck space of the measuring vessel into the overflow tube 9 is accelerated. The small amounts of liquid entering the pipe section 30 through the opening 32 at the moment when the measuring vessel is full are discharged into the overflow pipe 9 by the air flow sucked in from the line 17, so they do not affect the operation of the measuring device in any way.
Die beschriebene Einrichtung ist nicht nur für Zwillingsmeßgefäße von Bedeutung, sondern auch für einfache Meßgefäße vorteilhaft verwendbar.The device described is not only for twin measuring vessels of importance, but can also be used advantageously for simple measuring vessels.
