F 17C 13/06, 1988, deren Flanschbünde im Hals der Gasflasche eingewalzt sind.The following are used as lids: a cap, US Pat. No. 2 425 448, Kl. 220-3, 1947, on the neck of the gas bottle put on from above and welded to their frontal part is; a plug, U.S. Patent No. 2,630,936, Cl. 220-3, 1953, with a cylindrical tubular jacket that inside the neck of the gas bottle is arranged, the Plug has a horizontal ring flange, which on end part of the neck is welded; a closure plate, GB Patent No. 2,045,353, Cl.

F 17C 13/06, 1988, their flange collars rolled into the neck of the gas bottle.

Die am nächsten kommende Analogielösung ist die Konstruktion der Gasflasche, US-Patent Nr. 2 685 383, Kl. 220-3, 1954, die einen Körper mit einem Hals besitzt, in welchem der Schaft eines Stopfens untergebracht wird, dessen Flansche an der Stirnfläche des Halses angeschweißt sind.The closest analog solution is construction the gas bottle, U.S. Patent No. 2,685,383, Cl. 220-3, 1954, the has a body with a neck in which the shaft a plug is housed, the flanges on the End face of the neck are welded.

Nächstliegende Analogielösung des Verfahrens zum Füllen einer Gasflasche mit Gas ist ein Verfahren, US-Patent Nr. 2 685 383, Kl. 220-3, 1954, das die Unterbringung des Kohlendioxidgases in Form von "Trockeneis" im Inneren des Körpers der Gasflasche, das Verschließen des Flaschenhalses mit einem Stopfen, das Einpressen des Stopfens und das Anschweißen des Stopfenflansches an die Stirnfläche des Halses umfaßt.The closest analogy solution to the filling process a gas bottle with gas is a process, U.S. Patent No. 2 685 383, Kl. 220-3, 1954, which accommodates the carbon dioxide gas in the form of "dry ice" inside the body the gas bottle, closing the bottle neck with a Plugging, pressing in the plug and welding the Plug flange on the end face of the neck includes.

Für alle diese Vorrichtungen und das Füllverfahren sind folgende gemeinsame Nachteile charakteristisch. Beim Einfüllen beispielsweise von CO2 wird allerorts Trockeneis - Kohlendioxidgas in festem Zustand - verwendet. Das Trockeneis erhält man aus dem Flüssiggas. Dabei betragen die Verluste bei der Umwandlung des Kohlendioxidgases aus dem flüssigen Zustand in den festen Zustand∼30%. Die Arbeitsgänge des Füllens der Gasflasche, des Verschließens der Flasche mit einem Stopfen und des Anschweißens des Stopfens an den Flaschenhals sollen nacheinander mit einem minimalen Zeitintervall zwischen ihnen durchgeführt werden, um das Entweichen von Gas zu verringern. Die Gewährleistung eines solchen technologischen Prozesses erfordert die Schaffung von komplizierten und teuren Ausrüstungen.The following common disadvantages are characteristic of all these devices and the filling method. When filling in CO 2 , for example, dry ice - carbon dioxide gas in a solid state - is used everywhere. The dry ice is obtained from the liquid gas. The losses in the conversion of the carbon dioxide gas from the liquid state to the solid state are ∼30%. The operations of filling the gas bottle, sealing the bottle with a stopper, and welding the stopper to the neck of the bottle should be performed sequentially with a minimal interval between them to reduce gas leakage. Ensuring such a technological process requires the creation of complex and expensive equipment.

Offenbarung der ErfindungDisclosure of the invention

Der beanspruchten technischen Lösung liegt die Idee zugrunde, eine Gasflasche mit einem konstruktiv einfachen, fertigungsgerechten und leicht bedienbaren beweglichen Ventil in Form einer sphärischen Kugel zu schaffen. Dadurch kann die Gasflasche unmittelbar mit CO2 in flüssigem Zustand ausgefüllt werden, was die Voroperation der Umwandlung von CO2 aus dem flüssigen Zustand in den festen Zustand - in Trockeneis - überflüssig macht, d.h., beim Füllen der Gasflasche verringern sich die Verluste des Kohlendioxidgases mindestens um 30%. Der Einsatz eines derartigen beweglichen Ventils gestattet es, den Herstellungsprozeß einer gefüllten Gasflasche in zwei selbständige, in der Zeit gedehnte technologische Arbeitsgänge aufzuteilen:

  • Füllen der Flasche mit verflüssigtem Gas mit Möglichkeit einer langzeitigen Lagerung;
  • Verschließen mit einem Stopfen und dessen Anschweißen an die Flasche.
The technical solution claimed is based on the idea of creating a gas bottle with a structurally simple, production-oriented and easy-to-use movable valve in the form of a spherical ball. As a result, the gas bottle can be filled directly with CO 2 in the liquid state, which makes the pre-operation of converting CO 2 from the liquid state into the solid state - into dry ice - superfluous, i.e. when the gas bottle is filled, the losses of carbon dioxide gas are at least reduced by 30%. The use of such a movable valve allows the manufacturing process of a filled gas bottle to be divided into two independent, time-consuming technological operations:
  • Filling the bottle with liquefied gas with the possibility of long-term storage;
  • Seal with a stopper and weld it to the bottle.

Dadurch wird es möglich, die Anforderungen an die technologische Ausrüstung zu vereinfachen und als Folge davon die Kosten der Herstellung von Gasflaschen zu reduzieren.This makes it possible to meet the technological requirements Simplify equipment and as a result the Reduce the cost of manufacturing gas cylinders.

Dies wird dadurch erreicht, daß die Gasflasche, welche aus einem Körper mit Hals besteht, über einen Stopfen verfügt, der in den Hals der Flasche eingesetzt wird. Die Flansche des Stopfens sind an der Stirnfläche des Flaschenhalses angeschweißt, während in der Membran des Stopfene eine Ausnehmung vorhanden ist. Innerhalb des Körpers der Gasflasche ist vor dem Füllen derselben mit verflüssigtem Gas ein bewegliches Ventil - eine sphärische Kugel - untergebracht, deren Durchmesser größer ist als der Durchmesser der Öffnung im Hals. Die Lange des in den Hals eingesetzten Stopfenteils ist so bemessen, daß die Kugel nach dem Einsetzen des Stopfens die Öffnung des Halses nicht vollständig schließen kann.This is achieved in that the gas bottle, which from a body with a neck and a stopper that is inserted into the neck of the bottle. The flanges of the Stoppers are welded to the end face of the bottle neck, while a recess is present in the membrane of the stopper is. Inside the body of the gas bottle is before filling the same with liquefied gas a movable valve - one spherical ball - housed, the diameter of which is larger than the diameter of the opening in the neck. The length of the in the Neck part inserted is dimensioned so that the ball after inserting the stopper not opening the neck can completely close.

Damit die Kugel nach dem Durchstich der Membran des Stopfens den Gaszutritt aus der Gasflasche ins Innere des Stopfens nicht sperren kann, ist das im Hals untergebrachte Stopfenende mit einer Abschrägung ausgeführt oder beispielsweise als "Stern" eingewalzt.So that the ball after piercing the membrane of the Plug the gas inlet from the gas bottle into the inside of the Can not block stuffing, that is housed in the throat Plug end with a bevel or, for example rolled in as a "star".

    Die Gasflasche enthält einen Körper 1 mit einem Hals 2. Innerhalb des Körpers 1 ist eine Kugel 3 untergebracht (Fig. 1). Im Hals 2 ist ein Stopfen 4 eingesetzt, dessen Flansch 5 an der Stirnfläche 6 des Halses 2 angeschweißt ist (Fig. 3). In der Membran 7 des Stopfens 4 ist eine Ausnehmung 8 zur Erleichterung des Durchstichs der Membran 7 vorhanden, Das Stopfenende weist eine Abschrägung 9 auf (Fig. 5), oder es ist beispielsweise als "Stern" 10 eingewalzt (Fig. 6). Die Kugel 3 kann aus einem elastischen, federnden Material (Fig. 7), aus einem elastischen, federnden Material mit metallischem pulverförmigem Füllstoff, ganz aus Metall mit einer elastischen, federnden Hülle 11 hergestellt sein (Fig. 8), um ein bündiges Anliegen an den Wänden der Öffnung 12 des Halses 2 sicherzustellen.The gas bottle contains a body 1 with a neck 2. A ball 3 is accommodated within the body 1 (Fig. 1). In the neck 2, a plug 4 is inserted, the Flange 5 welded to the end face 6 of the neck 2 is (Fig. 3). There is a recess in the membrane 7 of the stopper 4 8 to facilitate the puncture of the membrane 7 present, the plug end has a bevel 9 (Fig. 5), or it is rolled, for example, as a "star" 10 (Fig. 6). The ball 3 can be made of an elastic, resilient Material (Fig. 7), made of an elastic, resilient Material with metallic powder filler, whole made of metal with an elastic, resilient sleeve 11 be (Fig. 8) to be flush against the walls to ensure the opening 12 of the neck 2.

    Das Füllen der Gasflasche geschieht folgendermaßen.The gas bottle is filled as follows.

    Die Gasflasche mit der im Körper 1 (Fig. 1) vorher untergebrachten Kugel 3 wird mit dem Hals 2 nach unten umgedreht und unter einem Druck von über 10000 hPa über den Hals 2 mit verflüssigtem Gas gefüllt. Unter dem Gasdruck in der Flasche sinkt die Kugel 3 nach unten und schließt die Öffnung 12 des Halses 2 vollständig dicht ab, indem sie eine Gasentweichung aus der Flasche verhindert. Die Flasche wird in die Normallage umgedreht (Fig. 2). In diesem Zustand kann die Gasflasche eine lange Zeit aufbewahrt werden. Dabei ist eine Gasentweichung aus der Gasflasche praktisch ausgeschlossen. Dann findet das Verschließen mit dem Stopfen 4 statt (Fig. 3), wobei das Ende des Stopfens 4 die Kugel 3 aus der Öffnung 12 des Halses 2 hinausstößt. Danach erfolgt das Einpressen des Stopfens 4 und das Anschweißen seines Flansches 5 an die Stirnfläche 6 des Halses 2. Des weiteren sinkt die Kugel 3 auf den Boden der Gasflasche, weil ihre Massedichte größer ist als die Massedichte des Gases und der Druck im Inneren der Gasflasche nach dem Anschweißen des Stopfens 4 an den Hals 2 konstant ist (Fig. 4).The gas bottle with the one previously housed in body 1 (Fig. 1) Ball 3 is turned upside down with neck 2 and under a pressure of over 10,000 hPa across the neck 2 filled with liquefied gas. Under the gas pressure in the Bottle drops the ball 3 down and closes the Opening 12 of the neck 2 completely tight by making a Gas leakage from the bottle prevented. The bottle will turned over to the normal position (Fig. 2). In this condition the gas bottle can be kept for a long time. there gas leakage from the gas bottle is practically impossible. Then it is closed with the stopper 4 instead (Fig. 3), the end of the plug 4, the ball 3rd pushes out of the opening 12 of the neck 2. After that is done pressing the plug 4 and welding his Flange 5 to the end face 6 of the neck 2. Furthermore ball 3 sinks to the bottom of the gas bottle because its Mass density is greater than the mass density of the gas and the Pressure inside the gas bottle after welding the Plug 4 to the neck 2 is constant (Fig. 4).
