Description

Nahtlose, dünnwandige Druckgasflasche Bei den bekannten Druckgasflaschen ist das Ventil meist in den starkwandigen Flaschenhals eingeschraubt. Die Flaschen haben entweder durchweg oder nur am Hals und an den Schultern eine verstärkte Wand. Es gibt auch Druckgasflaschen für mittlere Drücke, in deren Flaschenschultern ein starkwandiger Ring mit Innengewinde für das Ventil eingeschweißt ist.Seamless, thin-walled pressurized gas cylinder With the known pressurized gas cylinders the valve is usually screwed into the thick-walled bottle neck. The bottles have a reinforced wall either throughout or only on the neck and shoulders. There are also pressurized gas cylinders for medium pressures, in the cylinder shoulders thick-walled ring with internal thread for the valve is welded.

Die starkwandigen Flaschen sind nahtlos. Sie werden aus einem mit Boden versehenen Zylinder angefertigt, dessen offener Teil durch Walzen, Pressen oder Hämmern auf die Halsweite zum Einschrauben des Ventils verjüngt wird. Dies Verfahren ist wirtschaftlich durchführbar nur bis zu einer gewissen Mindestwandstärke je nach Durchmesser und Werkstoff des Zylinders. Bei kleineren Wandstärken entstehen während des Einziehens des Halses Risse und Falten. Sie machen die Flasche unbrauchbar. Daher wird der Hals- und Schulterteil für dünnwandige Flaschen gesondert mit einer starken Wand gefertigt und dann der übrige dünnwandige Flaschenteil an die Schulter angeschweißt. Dünnwandige Druckgasflaschen werden vorzugsweise für Flüssiggas, wie z. B. Propan, Propylen, Butan usw. und deren Gemische, sowie Rohrgasol benutzt. Sie bestehen ausschließlich aus Stahl.The thick-walled bottles are seamless. You become one with Bottom provided cylinder made, the open part by rolling, pressing or hammering to the neck width to screw in the valve is tapered. this The process is economically feasible only up to a certain minimum wall thickness depending on the diameter and material of the cylinder. With smaller wall thicknesses arise cracks and wrinkles during neck retraction. They make the bottle unusable. Therefore, the neck and shoulder part for thin-walled bottles is separately with a strong wall and then the remaining thin-walled part of the bottle on the shoulder welded on. Thin-walled pressurized gas cylinders are preferably used for liquid gas, such as z. B. propane, propylene, butane, etc. and their mixtures, as well as Rohrgasol used. They are made entirely of steel.

Die Erfindung hat sich die Aufgabe gestellt, eine dünnwandige nahtlose Druckgasflasche, insbesondere aus Leichtmetall, zu schaffen. Eine Leichtmetallflasche hat nämlich schon wegen ihres erheblich niedrigeren Gewichts wesentliche Vorzüge vor der Stahlflasche und noch weitere durch ihre nahtlose Form. Dabei braucht ihre Wandstärke nur so groß zu sein, daß sie sicher den vorgeschriebenen Füllungs-und Prüfdruck aushält. Bei geschweißter Ausführung ist eine erheblich größere Wandstärke wegen der geringeren Festigkeit der Schweißnaht notwendig.The invention has set itself the task of a thin-walled seamless To create pressurized gas cylinder, in particular made of light metal. A light metal bottle because of its considerably lower weight it has significant advantages in front of the steel bottle and others because of their seamless shape. You need Wall thickness only to be so great that it safely meets the prescribed filling and Test pressure endures. In the welded version, a considerably greater wall thickness is due the lower strength of the weld seam.

Unter einer dünnen Wand im erfindungsgemäßen Sinne wird eine Wandstärke verstanden, die kleiner als ih, des Zylinderdurchmessers ist.A thin wall in the sense of the invention is a wall thickness understood, which is smaller than ih, the cylinder diameter.

Die Erfindung geht dabei davon aus, daß sich das offene Ende von njahtlosen dünnwandigen Zylindern einwandfrei durch Drücken oder einen ähnlichen Verformungsvorgang verjüngen läßt. Solche nahtlos hergestellten Flaschenrohlinge sind erfindungsgemäß als Druckgasflaschen geeignet, wenn ihr dünnwandiger Hals kein eingeschnittenes Gewinde hat, sondern drucksicher in einen den Hals beiderseitig umschließenden Doppelkragen eingespannt ist. Der Innenkragen ist dabei mit Gewinde zum Einschrauben des Flaschenventils versehen.The invention assumes that the open end of seamless thin-walled cylinders by pressing or a similar deformation process rejuvenates. Such seamlessly produced bottle blanks are according to the invention Suitable as pressurized gas cylinders if their thin-walled neck does not have an incised one Has thread, but pressure-proof in a double collar that surrounds the neck on both sides is clamped. The inner collar is threaded for screwing in the cylinder valve Mistake.

Die Abb. i zeigt beispielsweise im Schnitt den Schulterteil einer solchen dünnwandigen Druckgasflasche mit dem drucksicher ihren dünnen Hals beiderseitig umschließenden Doppelkragen, der eine Bohrung zum Einschrauben des Flaschenventils hat. Abb. 2 ist eine Draufsicht. Darin bedeuten: i den nahtlos durch Drücken hergestellten dünnwandigen Flaschenrohling, 2° den den Flaschenhals umschließenden äußeren Kragen, 2b den in den Außenkragen drucksicher auf den Flaschenhals aufgeschraubten Innenkragen, 3 die mit Innengewinde versehene Bohrung für das Flaschenventil, 4 den flanschartig umgebördelten Flaschenhals, 5 den auf den Flansch des Flaschenhalses aufgelegten, zwischen Innen- und Außenkragen angeordneten Dichtungsring, gegen den der Innenkragen 2b drucksicher gepreßt wird, 6 die Verschlußkappe, 7 den Traggriff.Fig. I shows, for example, in section the shoulder part of a such thin-walled pressurized gas cylinder with the pressure-proof, thin neck on both sides surrounding double collar with a hole for screwing in the cylinder valve Has. Fig. 2 is a plan view. In it mean: i the seamlessly produced by pressing thin-walled bottle blank, 2 ° the outer collar surrounding the bottle neck, 2b the inner collar screwed pressure-proof onto the bottle neck in the outer collar, 3 the internally threaded hole for the cylinder valve, 4 the flange-like flanged bottle neck, 5 the one placed on the flange of the bottle neck, Sealing ring arranged between the inner and outer collar, against which the inner collar 2b is pressed in a pressure-proof manner, 6 the cap, 7 the handle.

Zur Herstellung des nahtlosen Flaschenrohlings wird zweckmäßigerweise ein Werkstoff benutzt, dessen offener Zylinderrand sich in weich geglühtem Zustand durch Drücken möglichst faltenlos und rissefrei zu einem Hals verjüngen und dann nach Umbördeln des Halsrandes in seinen Festigkeitseigenschaften veredeln läßt, wie z. B. die hochvergütbaren Aluminium-Legierungen der Gattung Al-Mg-Si. Nach dem Vergüten wird der Dichtungsring zwischen Außen- und Innenkragen eingelegt und der Innenkragen fest auf den Dichtungsring aufgepreßt. Die beiden auf den Hals aufgesetzten Stücke des Doppelkragens werden zweckmäßigerweise durch einen eingesteckten oder eingeschraubten Sicherungsbolzen gegen Verdrehen gesichert.For the production of the seamless bottle blank, it is expedient a material is used whose open cylinder edge is in a soft-annealed state by pressing, taper to a neck with as little wrinkles and cracks as possible and then after beading the edge of the neck can be refined in its strength properties, such as B. the highly heat treatable aluminum alloys of the type Al-Mg-Si. After this The sealing ring is placed between the outer and inner collar and the Inner collar pressed firmly onto the sealing ring. The two put on the neck Pieces of the double collar are expediently inserted or screwed-in safety bolt secured against twisting.

Das äußere oder innere Formstück des Doppelkragens kann auch mit einem Gewinde versehen werden. Die Flaschenkappe wird dann zum Schutz des Flaschenventils aufgeschraubt. Bei dieser Ausführungsform wird wie üblich ein Griff zum Tragen der Flasche an der Flaschenkappe befestigt oder angegossen.The outer or inner molding of the double collar can also be with a Threads are provided. The bottle cap is then used to protect the bottle valve unscrewed. In this embodiment, as usual, a handle for carrying the Bottle attached to the bottle cap or molded.

Das Auf- und Abschrauben der Flaschenkappe macht im Haushalt gewisse Schwierigkeiten. Sie werden vermieden, wenn der bisher an der Flaschenkappe angebrachte Tragbügel an den äußeren Verstärkungsring angebracht wird, der den Flaschenhals umfaßt. Zweckmäßigerweise werden dafür zwei Ohren an diesem Ring angebracht. Sie sind in der Abbildung mit 8 bezeichnet. Die Flaschenkappe wird zweckmäßigerweise federnd auf die zylindrische Verlängerung des äußeren oder inneren Formstückes federnd aufgeschoben. Die Formstücke haben nach einem weiteren Erfindungsgedanken einen tiefen, der Wandstärke der Kappe entsprechenden Schlitz. Er verhindert eine Verschiebung der Kappe, wenn die Flasche umfällt. Die Kappe ist mit einer Kette an dem äußeren Ring befestigt.Unscrewing and unscrewing the bottle cap does something in the household Trouble. They are avoided if the one previously attached to the bottle cap Carrying bracket is attached to the outer reinforcement ring that holds the bottle neck includes. For this purpose, two ears are expediently attached to this ring. she are labeled 8 in the figure. The bottle cap is expedient resiliently resiliently on the cylindrical extension of the outer or inner shaped piece postponed. According to a further idea of the invention, the fittings have a deep slot corresponding to the wall thickness of the cap. It prevents a shift the cap if the bottle falls over. The cap is attached to the outer with a chain Ring attached.
