Description

Die bekannten Behälter für flüssige Gase sind mit einer Wärmeisol;afion, insbesondere einer Vakuumisolation, versehen. Dabei sind die Entnahmerohre für die verflüssigten Gase durch die Wärmeisolation bzw. durch den Vakuummantel geführt. Beim Durchströmen: des flüssigen Gases durch die Entnahmeleitung verdampft Ffüssigkeit stets zu einem kleinen Teil infolge der nicht zu vermeidenden Wärmezufuhr. Diese wird zwar weitgehend durch eine Wärmeisolierung der Rohrleitung eingeschränkt. Sie ist .an der Stelle, an der das Entnahmerohr durch den Isolationsbehälter bzw. durch den Vakuummantel nach außen tritt, am stärksten, da an dieser Stelle der warme Außenmantel des Behälters unmittelbar mit der von dem verflüssigten Gas durdnströmenden Leitung in Berührung kommt und demzufolge der Wärmezufluß am größten ist.The known containers for liquid gases are with a thermal insulation; afion, in particular vacuum insulation. The extraction tubes are for the liquefied gases through the thermal insulation or through the vacuum jacket. When flowing through: the liquid gas through the extraction line evaporates liquid always to a small extent due to the unavoidable supply of heat. These is largely restricted by the thermal insulation of the pipeline. she is .at the point where the extraction pipe through the insulation container or through the vacuum jacket comes out, the strongest, because at this point the warm outer jacket of the container directly to the conduit flowing through the liquefied gas comes into contact and consequently the heat influx is greatest.

Die Erfindung :beseitigt die Nadhtei@le. Sie betrifft einen w.ärmeiso-fierten, insbesondere vakuumisolierten und. für Atemsthutzgeräte bestimmten Behälter für flüssige Gase -mit einem Entnahmerohr für diese und besteht darin, daß das Entnahmerohr in einem vorzugsweise zylinderförmigen Ansatz des Isolationsbehälters liegt, wobei der dem Entnahmerohr anliegende Teil des Ansatzes -in Ridhtung zum Behälter eingezogen und mit einem wärmeisolierenden Stoff gefüllt ist. Durch diese Ausbildung des Isotationsbehäfters wird vermieden, daß Wärme vom Außenmantel, soweit dkser unmittelbar mit der umgebenden Luft in Berührung kommt und deren Temperatur annimmt, auf das Entnahmerohr übergeht. Vielmehr wird der dem Entnahmerolhr unmittelbar anliegende Teil des Außenmantels selbst wieder wärmeisoliert.The invention: eliminates the needles. It concerns a warmly insulated person, especially vacuum insulated and. Containers designed for breathing apparatus for liquid gases -with an extraction pipe for this and consists in that the extraction pipe is in a preferably cylindrical extension of the insulation container, wherein the part of the extension lying against the extraction pipe -drawn in the direction of the container and filled with a heat insulating material. Through this training of the insulation container it is avoided that heat from the outer jacket, as far as it is directly with the surrounding Air comes into contact and its temperature assumes, transfers to the extraction pipe. Rather, the part of the outer jacket directly adjacent to the extraction pipe becomes itself again thermally insulated.

In der Zeichnung ist eine Ausführungsform der Erfindung an einem Aufbewalhrungsgefäß für flüssigen Sauerstoff im Schnitt dargestellt. Vorri Boden des kugelförmigen Behälters i, der von einem Vakuummantel 2 umgeben ist, führt die Leitung 3, in die seitl'ioh der Füllanschlizßstutzen ¢ mündet" zunächst zu dem handbetätigten Absperrventil 5, von da zu dem sieh selbsttätig bei einem bestimmten Druck schließenden Ventil 6 und von da zu dem Gasraum des Behälters. Von dieser Leitung zweigt die Entnahmeleitung 7 für den gasförmigen Sauerstoff ab, an d:ie das Überdruckventil 8 und das handbetätigte Absperrventil angeschlossen sind.In the drawing is an embodiment of the invention on a storage vessel shown in section for liquid oxygen. Vorri bottom of the spherical container i, which is surrounded by a vacuum jacket 2, leads the line 3 into the seitl'ioh the Füllanschlizßstutzen "opens" first to the manually operated shut-off valve 5, from there to the valve that closes automatically at a certain pressure 6 and from there to the gas space of the container. The extraction line branches off from this line 7 for the gaseous oxygen, to the pressure relief valve 8 and the manually operated one Shut-off valve are connected.

In den Boden, des Be'häl'ters mündet die Entnahmeleitung io für flüssigen 'Sauerstoff, die in einem rohrförmigen Ansatz i r des Vakuummantels :2 untergebracht ist. Der Ansatz i i ist in Richtung zum Behälter i eingezogen. Der außerhalb des Vakuummantels das Entnahmerohr io umgebende Wärmeisolätionsmantef 12 ragt in den eingezogenen Teil 13 des rohrförmigen Ansatzes i i hinein und füllt diesen aus. Der Wärmezufluß muß jetzt den verhältnismäßig langen Weg des eingezogenen Teiles i3 überwinden.The extraction line for liquid flows into the bottom of the container 'Oxygen, housed in a tubular extension i r of the vacuum jacket: 2 is. The approach i i is drawn in towards the container i. The outside of the Vacuum jacket, the extraction pipe io surrounding heat insulation jacket 12 protrudes into the retracted part 13 of the tubular extension i i and fills this out. The flow of heat must now cover the relatively long distance of the drawn-in part overcome i3.
