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 analogue solution is the construction of the gas cylinder, U.S. Patent No. 2,685,383, Kl. 220-3, 1954, which has a body with a neck in which the stem of a plug is housed, its flanges on the 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 analogue solution to the method of filling a gas cylinder with gas is a method, U.S. Patent No. 2,685,383, Kl. 220-3, 1954, which teaches to store the carbon dioxide gas in the form of "dry ice" inside the body of the gas cylinder Closing the bottle neck with a plug comprising pressing in the plug and welding the plug flange to the face of the neck.

US 2685383 wird als nächstliegender Stand der Technich augesehen und entspricht dem einleitenden Teil des Anspruches 1.US 2685383 will be considered to be the closest prior art and corresponds to the introductory part of claim 1.

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.For all these devices and the filling method, the following common disadvantages are characteristic. When filling, for example, CO 2 is everywhere dry ice - carbon dioxide gas in the solid state - used. The dry ice is obtained from the liquefied gas. The losses in the conversion of the carbon dioxide gas from the liquid state to the solid state ~ 30%. The operations of filling the gas cylinder, closing the bottle with a stopper and welding the stopper to the neck of the bottle are to be performed one after the other with a minimum time interval between them to reduce the escape of gas. Ensuring such a technological process requires the creation of complicated 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 Lagerang;
  • Verschließen mit einem Stopfen und dessen Anschweißen an die Flasche.
The claimed technical solution is based on the idea to provide a gas cylinder with a structurally simple, production-friendly and easy-to-use movable valve in the form of a spherical sphere. Thus, the gas cylinder can be filled directly with CO 2 in the liquid state, which makes the pre-operation of the conversion of CO 2 from the liquid state to the solid state - in dry ice - superfluous, ie, when filling the gas cylinder, the losses of carbon dioxide gas at least by 30%. The use of such a movable valve makes it possible to divide the manufacturing process of a filled gas cylinder into two independent, time-expanded technological operations:
  • Filling the bottle with liquefied gas with possibility of long-term storage;
  • Closing with a stopper and welding 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 simplify the requirements for the technological equipment and, as a consequence, to reduce the costs 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 Stopfens 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 Länge 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 by having the gas bottle, which consists of a body with a neck, with a plug which is inserted into the neck of the bottle. The flanges of the plug are welded to the face of the neck of the bottle, while in the membrane of the plug a recess is present. Within the body of the gas cylinder, prior to filling it with liquefied gas, a movable valve - a spherical ball - is housed whose diameter is larger than the diameter of the opening in the throat. The length of the plugging part inserted into the neck is dimensioned so that the ball can not completely close the opening of the neck after insertion of the plug.

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 can not block the gas inlet from the gas cylinder into the interior of the plug after the piercing of the membrane of the plug, the stopper end accommodated in the neck is designed with a chamfer or, for example, rolled as a "star".

Das Verhältnis der gemittelten Massedichte von Werkstoffen, aus denen die Kugel gefertigt ist, und des Kugeldurchmessers wird derart gewählt, daß nach dem Füllen der Gasflasche vor dem Verschließen mit dem Stopfen die Kugel unter dem Gasdruck, der den Umgebungsdruck etwa um das 60-fache übersteigt, nicht durch den Hals hinausspringen kann.The ratio of the average mass density of materials making up the sphere and the diameter of the sphere is such that after filling the gas bottle before closing with the stopper, the sphere will be under gas pressure which exceeds the ambient pressure by approximately 60 times , can not jump out of the neck.

Die Kugel kann aus einem elastischen, federnden Material, aus einem elastischen, federnden Material mit metallischem pulverförmigem Füllstoff, ganz aus Metall in einer elastischen, federnden Hülle hergestellt sein.The ball can be made of an elastic, resilient material, made of an elastic, resilient material with metallic powdery filler, made entirely of metal in an elastic, resilient shell.

In dem erfindungsgemäß vorgeschlagenen Verfahren zum Füllen der Gasflasche bringt man vor dem Füllvorgang ins Innere des Körpers der Flasche ein bewegliches Ventil ein, dreht dann die Flasche mit dem Hals nach unten um und füllt sie unter . Druck mit verflüssigtem Gas, vermindert danach den Fülldruck, wobei das bewegliche Ventil durch die Wirkung des Gasdrucks im Inneren der Flasche die Öffnung in dem Hals abschließt, so, daß die Flasche eine lange Zeit ohne Gasentweichung aus ihr aufbewahrt werden kann, worauf man das Verschließen des Halses mit dem Stopfen, das Einpressen des Stopfens und das Anschweissen des Stopfenflansches an die Stirnfläche des Halses vornimmt.In the proposed method for filling the gas cylinder according to the invention is brought before the filling process into the interior of the body of the bottle, a movable valve, then turns the bottle with the neck down and fills it. Pressure with liquefied gas, then reduces the filling pressure, wherein the movable valve closes the opening in the neck by the effect of the gas pressure inside the bottle, so that the bottle can be stored for a long time without gas leakage, followed by closing the neck with the plug, pressing the plug and welding the plug flange to the face of the neck.

Beste Ausführungsform der ErfindungBest embodiment of the invention

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. Inside the body 1 is housed a ball 3 (FIG. 1). In the neck 2, a plug 4 is inserted, the flange 5 is welded to the end face 6 of the neck 2 (Fig. 3). In the membrane 7 of the plug 4, a recess 8 for facilitating the puncture of the membrane 7 is present. The plug end has a chamfer 9 (Figure 5), or it is, for example, rolled as a "star" 10 (Figure 6). The ball 3 may be made of a resilient, resilient material (Figure 7) made of a resilient, resilient material with metallic powdered filler made entirely of metal with a resilient, resilient sheath 11 (Figure 8) for a flush fit to ensure the walls of the opening 12 of the neck 2.

Das Füllen der Gasflasche geschieht folgendermaßen.The filling of the gas cylinder is done 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 ball 3 previously accommodated in the body 1 (FIG. 1) is turned down with the neck 2 and filled with liquefied gas via the neck 2 under a pressure of over 10000 hPa. Under the gas pressure in the bottle, the ball 3 sinks down and closes the opening 12 of the neck 2 completely tightly by preventing gas leakage from the bottle. The bottle is turned over to the normal position (Fig. 2). In this condition, the gas cylinder can be stored for a long time. In this case, a gas leakage from the gas cylinder is practically impossible. Then the closing takes place with the stopper 4 (FIG. 3), wherein the end of the stopper 4 is the ball 3 out of the opening 12 of the neck 2 pushes. Thereafter, the pressing of the plug 4 and the welding of its flange 5 to the end face 6 of the neck 2. Furthermore, the ball 3 sinks to the bottom of the gas cylinder, because its mass density is greater than the mass density of the gas and the pressure inside the gas cylinder after welding the plug 4 to the neck 2 is constant (Fig. 4).
