Description

Regelbare Beheizung von flüssigem Sauerstoff. Die Erfindung betrifft die regelbare Beheizung von flüssigem Sauerstoff durch den verdampften Sauerstoff, welcher, nachdem er in einer Rohrleitung einen Teil seiner Kälte mit der umgebenden Luft ausgetauscht hat, wieder durch den flüssigen Sauerstoff geführt wird. Nach der Erfindung öffnet der verdampfte Sauerstoff bei einem gewissen Druck ein Ventil entgegen einem Außendruck und strömt direkt ohne Beheizung des flüssigen Sauerstoffes in die Verbrauchsleitung, während bei einem geringeren Verdampfungsdruck das Ventil durch den Gegendruck wieder geschlossen wird.Adjustable heating of liquid oxygen. The invention relates to the controllable heating of liquid oxygen by the vaporized oxygen, which, after being in a pipeline, part of its coldness with the surrounding area Air has exchanged, is again passed through the liquid oxygen. To According to the invention, the vaporized oxygen opens a valve at a certain pressure against an external pressure and flows directly without heating the liquid oxygen into the consumption line, while at a lower evaporation pressure the valve is closed again by the counter pressure.

Ein Apparat zur Ausführung der Erfindung ist nachstehend beschrieben und auf der Zeichnung im Querschnitt und in Oberansicht dargestellt.Apparatus for carrying out the invention is described below and shown on the drawing in cross section and in top view.

Abb. 3 zeigt einen Schnitt durch einen Einzelteil.Fig. 3 shows a section through an individual part.

Für den Erfindungszweck wird ein zur Füllung mit flüssigem Sauerstoff geeignetes Gefäß benutzt.For the purpose of the invention, one is used for filling with liquid oxygen suitable vessel used.

Der Sauerstoff soll unter einem verhältnismäßig geringen Druck, beispielsweise zum Betrieb von Schweiß- und Schneidbrennern ausreichend, verdampft werden.The oxygen should be under a relatively low pressure, for example sufficient to operate welding and cutting torches.

Der Verdampfer B bildet vorteilhaft einen vom Gefäß abnehmbaren Teil, damit er beim Transport keine Außenwärme zu dem flüssigen Sauerstoff leitet.The evaporator B advantageously forms a part that can be removed from the vessel, so that it does not conduct any external heat to the liquid oxygen during transport.

Die unten miteinander kommunizierenden Rohre d' und e, auswechselbare Teile des Verdampfers B, werden in das mit flüssigem Sauerstoff gefüllte Gefäß A eingeschoben, das mit dem Verdampfer B durch den Bajonettverschluß f gasdicht verbunden wird.The pipes d 'and e communicating with each other below, interchangeable Parts of the vaporizer B are placed in the vessel A filled with liquid oxygen inserted, which is gas-tight connected to the evaporator B by the bayonet lock f will.

Durch den Wärmeaustausch der Rohre e und d' mit dem flüssigen Sauerstoff erfolgt sofort eine starke Verdampfung. Der verdampfte Sauerstoff strömt in das Rohr d, tauscht einen Teil seiner Kälte mit der umgebenden Luft aus, wird durch die Verlängerung d' des Rohres d wieder durch den flüssigen Sauerstoff geführt, um diesen zu beheizen, und tritt dann durch das Rohr e in die Kammer g mit dem Auslaß dz (s. auch Abb. 3).As a result of the heat exchange between the tubes e and d 'with the liquid oxygen, there is immediate strong evaporation. The vaporized oxygen flows into the tube d, exchanges part of its coldness with the surrounding air, is passed through the extension d 'of the tube d again through the liquid oxygen to heat it, and then passes through the tube e into the Chamber g with outlet dz (see also Fig. 3).

Die Decke der Kammer g ist von einer Membran i. gebildet. Die durch Schraube k verstellbare Druckfeder l belastet die 1\l:embran i.The ceiling of the chamber g is covered by a membrane i. educated. The compression spring l, adjustable by screw k, loads the 1 \ l: embran i.

An der Membran i .ist durch Stab m das Ventil iz befestigt, welches einen weiteren Einlaß o am Boden der Kammerg verschließt.The valve iz, which closes a further inlet o at the bottom of the chamber g, is attached to the membrane i by means of a rod m.

Ein größerer Sauerstoffdruck als der Gegendruck der Feder l hebt die Membran i und mit dieser das Ventil n; gleichzeitig wird durch ein am Ventil n befestigtes Ventil p der Zutritt des verdampften Sauerstoffes in das Rohr d gesperrt. Der verdampfte Sauerstoff strömt jetzt durch Öffnung o direkt in die Kammer g, und die Beheizung durch den verdampften Sauerstoff hört auf.A higher oxygen pressure than the counter pressure of the spring 1 lifts the membrane i and with it the valve n; At the same time, a valve p attached to the valve n blocks the entry of the vaporized oxygen into the pipe d. The evaporated oxygen now flows through opening o directly into chamber g, and the heating by the evaporated oxygen stops.

Vermindert sich der Sauerstoffdruck in der Kammer g, so wird durch den größeren Gegendruck der Feder L die Öffnung o wieder verschlossen und das Rohr d geöffnet.If the oxygen pressure in chamber g is reduced, then through the greater counter pressure of the spring L, the opening o closed again and the tube d open.

Die Erfindung kann auch für die Verdampfung von anderen flüssigen Gasen Verwendung finden.The invention can also be used for the evaporation of other liquid Gases are used.

Regelbare Beheizung von flüssigem Sauerstoff durch den verdampften Sauerstoff, der nach Wärmeaustausch mit der umgebenden Luft durch den flüssigen Sauerstoff wieder durchgeleitet wird, dadurch gekennzeichnet, .daß der verdampfende Sauerstoff ein unter einem äußeren Druck stehendes Ventil beeinflußt, das er bei Erreichung eines gewissen Druckes öffnet, so daß er dann durch dieses Ventil unmittelbar in die Verbrauchsleitung strömt, während bei geringerem Verdampfungsdruck das Ventil geschlossen bleibt, so daß dann der verdampfte Sauerstoff vor Ableitung in die Verbrauchsleitung nochmals durch den flüssigen Sauerstoff geleitet wird. PATIN T CLAIMS: i. Controllable heating of liquid oxygen by the evaporated oxygen, which after heat exchange with the surrounding air is passed through again by the liquid oxygen, characterized in that the evaporating oxygen influences a valve under an external pressure, which it opens when a certain pressure is reached so that it then flows through this valve directly into the consumption line, while the valve remains closed when the evaporation pressure is lower, so that the evaporated oxygen is then passed through the liquid oxygen again before it is discharged into the consumption line. 2. Einrichtung nach Anspruch i, dadurch gekennzeichnet, daß das Ventil mit einer von Hand einstellbaren äußeren Druckbelastung, die zwischen dem Auslaß des Sauerstoffbehälters und der Verbrauchsleitung eingeschaltet ist, und mit einer Absperrvorrichtung versehen ist, die beim Öffnen des Ventils die den verdampften Sauerstoff in .das Gefäß zurückführende Leitung abschließt.2. Device according to claim i, characterized in that the valve with a manually adjustable external pressure load between the outlet of the Oxygen tank and the consumption line is switched on, and with a shut-off device is provided that when the valve is opened, the evaporated oxygen in .das Closes the line leading back to the vessel.
