Description
Abmeßgerät mit einer oder mehreren Meßkammern Die Erfindung bezieht sich auf Abmeßgeräte für Flüssigkeiten mit einer oder mehreren Meßkammern und verfolgt "den Zweck, das Abtropfen von Flüssigkeitsresten, die, sich in dem Ablaufstutzen des Geräts ansammeln, zu unterbinden.Measuring device with one or more measuring chambers The invention relates on measuring devices for liquids with one or more measuring chambers and tracked "The purpose of the drainage of residual liquid that is in the drainage nozzle accumulate on the device.
Dieses Abtropfen ist bei den verschiedenen Arten von Meßgeräten durch verschiedenartige Umstände bedingt.This dripping occurs with the various types of measuring devices various circumstances.
Wenn der Ablaufstutzen sich unmittelbar an das untere Ende der Meßkammer anschließt, rieselt die näch dem Entnahmevorgang an der Innenwand der Kammer haftende Flüssigkeit allmählich in den Ablaufstutzen, so daß sich in dem Stutzen ein Flüssigkeitspfropfen bildet, von welchem sich nach einiger Zeit .ein Tropfen oder sogar mehrere Tropfen loslösen. Bei der praktischen Abmessung wird diese Loslösung von Tropfen in der Regel nicht abgewartet, weil damit ein empfindlicher Zeitverlust verbunden wäre.When the drain connection is located directly at the lower end of the measuring chamber afterwards, the next trickle of the removal process adhering to the inner wall of the chamber Liquid gradually into the drainage nozzle, so that there is a plug of liquid in the nozzle forms, from which after some time .a drop or even several drops detach. In the practical dimension, this detachment of drops in the As a rule, do not wait because this would entail a significant loss of time.
Wenn die Flüssigkeit aus der Meßkammer abgehebert wird, so bleibt nach jeder Abfüllung ein Flüssigkeitspfropfen in dem Ablaufende des Hebers stehen. Bei. Neufüllung der Kammer wird die Luft in dem Heber entsprechend dem statischen Druck der Neufüllung zusammengedrückt, so daß der stehengebliebene Flüssigkeitspfropfen aus dem Ablaufende des Hebers mehr oder weniger herausgedrängt wird und einen oder mehrere sich von selbst lösende Tropfen bildet. Diese Tropfen werden in der Regel nicht aufgefangen; im: übrigen wäre auch diese Maßnahme mit einem empfindlichen Zeitverlust verbunden und würde besondere Aufmerksamkeit des Bedienungspersonals erforderlich machen.When the liquid is siphoned off from the measuring chamber, it remains After each filling there is a plug of liquid in the outlet end of the siphon. At. Refilling the chamber will keep the air in the lifter corresponding to the static The pressure of the refill is compressed, so that the remaining plug of liquid is more or less pushed out of the drain end of the lifter and one or forms several self-dissolving drops. These drops are usually not caught; Incidentally, this would also be a sensitive measure Loss of time and would require special attention from the operating staff make necessary.
Erfindungsgemäß wird die Bildung und die Loslösung von Tropfen dadurch vermieden, daß an die Meßkammer des Geräts eine Entnahmekammer angeschlossen ist, aus der die Flüssigkeit durch einen an sich bekannten heberartigen Überlauf abfließt. Die abgemessene Flüssigkeit muß also vor Eintritt in das Auffanggefäß erst die Entnahmekammer durchfließen, so daß Flüssigkeitsreste, die nach einem Abfüllvorgang oder bei Neufüllung der Meßkammer bei den bekannten Geräten sich selbsttätig lösende Tropfen bildeten, in der mit einem-heberartigen Überlauf ausgestatteten Entnahmekammer festgehalten werden.According to the invention, the formation and detachment of drops is thereby achieved avoided that a sampling chamber is connected to the measuring chamber of the device, from which the liquid flows through a known siphon-like overflow. The measured liquid must therefore first enter the removal chamber before it enters the collecting vessel flow through, so that liquid residues after a filling process or when refilling self-acting drops formed in the measuring chamber in the known devices, held in the removal chamber equipped with a siphon-like overflow will.
Der Gegenstand der Erfindung ist in der Zeichnung in beispielsweiser Ausführung dargestellt.The object of the invention is shown in the drawing by way of example Execution shown.
Das Abmeßgerät besteht aus dem mit Flüssigkeit gefüllten Behälter i, in dessen Ablaufstutzen z ein Abmeßhahn 3 eingebaut ist. Der Stutzen z ist unterhalb des Hahns 3 als Entnahmekammer q. ausgebildet, aus welcher die Flüssigkeit durch einen heberartigen überlauf 5 ausströmen kann. Der Abmeßhahn 3 enthält zwei Meßkammern 6, welche in an sich bekannter Weise je eine Öffnung 7 für den Flüssigkeitsein- und -austritt und je eine Belüftungsöffnung 8 aufweisen. Die Öffnungen 7 .und 8 der beiden Meßkammern 6 sind um i8o° gegeneinander versetzt, so daß die Kammern bei Verdrehung des Hahns 3 um 18o' wechsehveise in die Füll- und Ablaufstellung gebracht werden und die Belüftung der Meßkammern 6 durch die Öffnungen 9 im Hahngehäuse jeweils nur in der Ablaufstellung stattfindet.The measuring device consists of the container filled with liquid i, a metering cock 3 is installed in the outlet nozzle z. The nozzle z is below of the cock 3 as a removal chamber q. formed from which the liquid passes through a siphon-like overflow 5 can flow out. The metering cock 3 contains two measuring chambers 6, which in a known manner each have an opening 7 for the liquid inlet and outlet and each have a ventilation opening 8. The openings 7. And 8 of the two measuring chambers 6 are offset from one another by 180 °, so that the chambers when turning the tap 3 by 18o ', alternate between the filling and draining positions are brought and the ventilation of the measuring chambers 6 through the openings 9 in the tap housing only takes place in the drain position.
Bei der gezeigten Darstellung steht die linke Meßkammer 6 über ihre Öffnung 7 mit dem Ablaufstutzen a des Behälters i in Verbindung, so daß sie mit Flüssigkeit aus dem Behälter i gefüllt wird. Die rechte Kammer 6 steht einerseits über ihre Öffnung 7 mit der Entnahmekammer ¢ und andererseits über ihre Öffnung 8 und die ihr zugeordnete Öffnung 9 mit der Außenluft in Verbindung. Bei Verdrehung des Hahns tun i 8o' sind die Verbindungen der beiden Kammern 6 umgekehrt, so daß die Flüssigkeit aus der linken Kammer 6 in die Entnahmekammer q. ab.strämen kann. Sobald der Flüssigkeitsspiegel in der Entnahmekammer die Krümmung des Hebers 5 erreicht, beginnt der Auslauf der Flüssigkeit, der so lange andauert, bis der Flüssigkeitsspiegel bis an die Kante des Hebersaugendes gesunken ist. Die an der Innenwand der Meßkammer haftende und allmählich in die Entnahmekammer rieselnde Flüssigkeit sammelt sich hier; ihre Menge reicht aber nicht aus, um den überlaufheber 5 erneut zur Wirkung kommen zu lassen oder den im Ablaufende desselben stehengebliebenen Flüssigkeitspfropfen zu verdrängen.In the illustration shown, the left measuring chamber 6 is above its Opening 7 with the drain port a of the container i in connection, so that it is with Liquid is filled from the container i. The right chamber 6 is on the one hand via its opening 7 with the removal chamber [and on the other hand via its opening 8 and the opening 9 associated with it in connection with the outside air. When twisted of the cock do i 8o 'the connections of the two chambers 6 are reversed, so that the liquid from the left chamber 6 into the removal chamber q. can stream. As soon as the liquid level in the removal chamber reaches the curvature of the lifter 5, the liquid begins to run out, which continues until the liquid level rises has sunk to the edge of the siphon suction end. The one on the inside wall of the measuring chamber Liquid that adheres and gradually trickles into the removal chamber collects here; However, their amount is not sufficient to make the overflow lifter 5 take effect again to come or the plug of liquid that has remained in the end of the drain to displace.
