Schaumdrosselfoam throttle
Beschreibungdescription
Die Erfindung betrifft eine Schaumdrossel für einen Zapfhahn zur Entnahme von Flüssigkeit aus einem Behälter mit einer Laufbuchse aus Kunststoff, in der ein Kolben geführt ist und die eine Durchtrittsoffnung für die Flüssigkeit aufweist, die der Kolben in einer eingefahrenen Sperrstellung dicht verschließt und in einer ausgefahrenen Entnahmestellung freigibt.The invention relates to a foam throttle for a tap for removing liquid from a container with a plastic liner, in which a piston is guided and which has a passage opening for the liquid, which the piston closes tightly in a retracted locking position and in an extended removal position releases.
Derartige Zapfhähne sind aus der DE 198 25 929 AI, WO 02/072 469 AI und WO 02/090 239 AI bekannt. Sie kommen hauptsächlich zum Einsatz, um unter Druck abgefüllte, kohlensäurehaltige Flüssigkeiten, insbesondere Getränke, aus Fässern, Kleinfässern (Partyfässern) oder Dosen zu entnehmen. Speziell geht es um Partyfässer für Bier.Such taps are known from DE 198 25 929 AI, WO 02/072 469 AI and WO 02/090 239 AI. They are mainly used to remove carbonated liquids, especially drinks, from barrels, small barrels (party barrels) or cans. It is especially about party kegs for beer.
Bier wird traditionell mit C02 unter Überdruck gezapft. Diese Technik ist in der Gastronomie weit verbreitet. Sie hat den Vorteil, daß das Bier mit C02 im wesentlichen gesättigt zum Abnehmer kommt. Das -ist für Frische, Qualität und Geschmack des Biers unübertroffen.Beer is traditionally tapped with C0 2 under excess pressure. This technique is widely used in the catering industry. It has the advantage that the beer is saturated with C0 2 to the customer. This is unmatched for the freshness, quality and taste of the beer.
Mit Partyfässern für Bier wurde ursprünglich das Konzept verfolgt, die Zapftechnik mit C02 in den Hausgebrauch zu bringen. Es gibt Zapfarma- turen mit C02-Patronen, die ein Anstechrohr haben, das durch ein Spundloch an der oberen Kuppe des Partyfasses bis an dessen Boden eingeführt wird. Es wird C02 unter Überdruck in den Kopfräum des Fasses eingespeist, um das Bier durch das Anstechrohr hochzufördern und auszugeben. Dabei kann die Qualität des Biers beeinträchtigt werden, da der C02-Überdruck nicht geregelt ist. Ist der Druck zu niedrig, so gast C02 aus dem Bier aus, und das Bier wird schal. Ist der Druck zu hoch, so tritt eine Überkarbonatisierung des Biers ein, mit der eine Verschlechterung des Geschmacks einhergeht. Viele Abnehmer scheuen auch den Umgang mit C02-Patronen und das als umständlich und kostenträchtig empfundene Zapfen damit. Ein Partyfaß Bier läßt sich ohne C02 durch Schwerkraftwirkung bei gleichzeitigem Druckausgleich entleeren. Zu diesem Zweck wurde ein in ein Partyfaß integrierter Zapfhahn der eingangs genannten Art entwik- kelt. Der Zapfhahn kommt zusammen mit einem von Hand zu betätigenden Druckausgleichsventil in einem Spundloch an der oberen Kuppe des Fasses zum Einsatz. Der Verbraucher kann das Faß über das Ventil belüften und eine drucklose Entleerung allein durch die Schwerkraft herbeiführen.With party kegs for beer the concept was originally pursued to bring the tap technology with C0 2 into domestic use. There are taps with C0 2 cartridges that have a piercing pipe that is inserted through a bunghole on the top of the party barrel to the bottom. C0 2 is fed into the head space of the keg under excess pressure in order to convey the beer up through the tapping pipe and to dispense it. The quality of the beer can be affected as the C0 2 pressure is not regulated. If the pressure is too low, C0 2 will emit gas from the beer and the beer will become stale. If the pressure is too high, over-carbonation of the beer occurs, which is accompanied by a deterioration in taste. Many customers also shy away from handling C0 2 cartridges and the cones that are perceived as cumbersome and costly. A party keg of beer can be emptied without C0 2 by gravity with simultaneous pressure equalization. For this purpose, a tap integrated into a party keg of the type mentioned was developed. The tap is used together with a manually operated pressure compensation valve in a bung hole on the top of the barrel. The consumer can vent the drum via the valve and bring about an unpressurized emptying solely by gravity.
Nachteilig dabei ist, daß das Bier mit Luftsauerstoff in Kontakt kommt, und daß C02 aus dem Bier ausgast. Abhilfe wird in einem C02- Spender gesehen, der sich im Innern des Partyfasses befindet und bei erstmaligem Zapfen einen geregelten C02-Überdruck in den Kopfraum des Fasses abgibt. Der C02-Spender wird von dem Verbraucher genauso aktiviert, wie derzeit das Druckausgleichsventil an der Kuppe des Fasses. Der C02-Überdruck gewährleistet, daß das vorhandene C02 im Bier gelöst bleibt und kein Sauerstoff in den Kopfräum des Fasses gelangt.The disadvantage here is that the beer comes into contact with atmospheric oxygen and that C0 2 outgasses the beer. Remedy is seen in a C0 2 dispenser, which is located inside the party keg and releases a regulated C0 2 overpressure into the head space of the keg when tapped for the first time. The C0 2 dispenser is activated by the consumer in exactly the same way as the pressure compensation valve on the top of the barrel. The C0 2 overpressure ensures that the existing C0 2 remains dissolved in the beer and that no oxygen gets into the head space of the keg.
Für den C02-Überdruck im Kopfräum des Fasses werden ca. 0,6 bis 0,8 Bar angestrebt. Gegenüber dem derzeitigen Stand, das Faß mit Druckausgleich bei Atmosphärendruck allein durch die Schwerkraft zu entleeren, bedeutet das eine deutliche Erhöhung des Förderdrucks. Die Konsequenz ist, daß praktisch nur noch Schaum gezapft wird.For the C0 2 overpressure in the head space of the barrel, approx. 0.6 to 0.8 bar are aimed for. Compared to the current status of emptying the drum with pressure compensation at atmospheric pressure solely by gravity, this means a significant increase in the delivery pressure. The consequence is that practically only foam is tapped.
Aufgabe der Erfindung ist es, eine Schaumdrossel zu schaffen, mit der sich ein Zapfhahn der eingangs genannten Art auf einfache, montagefreundliche Weise nachrüsten und bei Bedarf an ein Zapfen mit C02 unter Überdruck anpassen läßt, so daß Bier und Schaum in einem angemessenen Verhältnis ausgegeben werden.The object of the invention is to provide a foam throttle with which a tap of the type mentioned can be retrofitted in a simple, assembly-friendly manner and, if necessary, can be adapted to a spigot with C0 2 under excess pressure, so that beer and foam are dispensed in an appropriate ratio become.
Die diese Aufgabe lösende Schaumdrossel besteht aus einer vor der Durchtrittsoffnung auf die Laufbuchse des Zapfhahns aufsetzbaren, die Durchtrittsoffnung überdeckenden Haube, die mit der Laufbuchse einen Labyrinthkanal einschließt, der einends zum Innern des Behälters hin offen ist und der andernends in die Durchtrittsoffnung mündet. Bei einer bevorzugten Ausführungsform hat der Labyrinthkanal einen mä- anderförmigen Verlauf.The foam throttle that solves this task consists of a hood that can be placed in front of the passage opening on the nozzle of the tap and covers the passage opening, which includes a labyrinth channel with the sleeve, which is open towards the inside of the container at one end and opens into the passage opening at the other end. In a preferred embodiment, the labyrinth channel has a meandering course.
Bei einer bevorzugten Ausführungsform befindet sich das offene Ende des Labyrinthkanals nahe dem äußeren Ende der Laufbuchse. Das ist für die Restentleerung des Gebindes von Bedeutung. Der Zapfhahn ist dicht über dem Boden des Gebindes angeordnet, das zur Entnahme des Flüssigkeitsrests gekippt wird. Dabei muß sich ein Flüssigkeitspegel am offenen Ende des Labyrinthkanals einstellen.In a preferred embodiment, the open end of the labyrinth channel is near the outer end of the liner. This is important for the residual emptying of the container. The tap is located just above the bottom of the container, which is tilted to remove the liquid residue. A liquid level must be set at the open end of the labyrinth channel.
Der Labyrinthkanal kann sowohl auf dem Außenmantel der Laufbuchse, als auch auf dem Innenmantel der Haube ausgebildet sein. Bei letzterer Ausführungsform kann der Labyrinthkanal in einer Stichbohrung durch die Haube enden oder an einer Stirnseite der Haube auslaufen. In dieser Variante befindet sich die Öffnung des Labyrinthkanals noch näher am Ende der Laufbuchse.The labyrinth channel can be formed both on the outer jacket of the liner and on the inner jacket of the hood. In the latter embodiment, the labyrinth channel can end in a tap hole through the hood or run out on an end face of the hood. In this variant, the opening of the labyrinth channel is even closer to the end of the liner.
Bei einer bevorzugten Ausführungsform läßt sich die Haube auf die Laufbuchse aufclipsen. Die Haube kann sowohl vollzylindrisch, als auch teilzylindrisch sein. In letzterer Variante hat die Haube einen Um- schlingungswinkel von mehr 180°, vorzugsweise ca. 220°. Sie hält so unter leichter Spreizung durch Eigenelastizität an der Laufbuchse fest.In a preferred embodiment, the hood can be clipped onto the liner. The hood can be both fully cylindrical and partially cylindrical. In the latter variant, the hood has a wrap angle of more than 180 °, preferably approximately 220 °. It holds on to the liner with slight spreading due to its own elasticity.
Bei einer bevorzugten Ausführungsform ist die Laufbuchse an ihrem Aus- senmantel mit Rippen versehen. Die Haube der Schaumdrossel hat Ausnehmungen, die zwecks Positionierung über diese Rippen passen.In a preferred embodiment, the liner is provided with ribs on its outer jacket. The hood of the foam restrictor has recesses that fit over these ribs for positioning.

Der Zapfhahn besteht aus einer Laufbuchse 10, einem Kolben 12 und einer Schaumdrossel 14.The tap consists of a liner 10, a piston 12 and a foam throttle 14.
Die Laufbuchse 10 hat einen kreiszylinderischen Becherkörper 16, dessen Boden 18 an ihrem inneren Ende geschlossen ist. Am äußeren Ende der Laufbuchse 10 ist ein sich konisch erweiternder Spund aus elastischem Material angeformt, der eine flanschartige äußere Anlagepartie 20, eine dahinter zurückspringende umlaufende Dichtpartie 22 und eine vor der Dichtpartie 22 befindliche, umlaufende konische Rastpartie 24 hat, deren Durchmesser größer ist als der der Dichtpartie 22.The liner 10 has a circular cylindrical cup body 16, the bottom 18 of which is closed at its inner end. At the outer end of the bushing 10, a conically expanding sheet of elastic material is formed, which has a flange-like outer contact section 20, a circumferential sealing section 22 which recesses behind it and a circumferential conical latching section 24 located in front of the sealing section 22, the diameter of which is larger than that the sealing section 22.
Der Zapfhahn wird als komplett vormontierte Einheit aus Laufbuchse 10, Kolben 12 und Schaumdrossel 14 in die runde Öffnung eines Behälters eingedrückt, der eine zu zapfende Flüssigkeit enthält. Es handelt sich dabei um eine drucklos oder unter Druck abgefüllte Flüssigkeit, die Kohlensäure enthalten kann. Speziell geht es um das Zapfen von -Getränken, insbesondere Bier, aus Fässern, Kleinfässern (Partyfässern) oder Dosen. Der Zapfhahn wird mit dem Becherkörper 16 und der konischen Rastpartie 24 der Laufbuchse 10 voran in die Öffnung des Behälters eingedrückt. Die umlaufende Dichtpartie 22 nimmt den Rand der Öffnung unter Abdichtung auf, so daß er zwischen der flanschartigen Anlagepar- tie 20 und der Rastpartie 24 der Laufbuchse 10 zu liegen kommt, mit der letztere am Rand der Öffnung einrastet.The tap is pressed as a completely preassembled unit consisting of liner 10, piston 12 and foam throttle 14 into the round opening of a container which contains a liquid to be tapped. It is a pressureless or pressurized liquid that can contain carbonic acid. In particular, it is about tapping beverages, especially beer, from barrels, small barrels (party barrels) or cans. The tap is pressed into the opening of the container with the cup body 16 and the conical locking portion 24 of the bushing 10 first. The circumferential sealing part 22 receives the edge of the opening with a seal, so that it comes to lie between the flange-like contact part 20 and the locking part 24 of the bushing 10, with which the latter engages at the edge of the opening.
Zur Ausrichtung der Laufbuchse 10 bezüglich des Kolbens 12 bei der Montage des Zapfhahns sind am Außenmantel ihres Becherkörpers 16 vier gleichmäßig über den Umfang versetzte Rippen 26 angeformt, die sich in Längsrichtung der Laufbuchse 10 erstrecken.To align the liner 10 with respect to the piston 12 during assembly of the tap, four ribs 26, which are offset uniformly over the circumference and which extend in the longitudinal direction of the liner 10, are formed on the outer jacket of their cup body 16.
Die Laufbuchse 10 hat in der Mantelwand ihres Becherkörpers eine Durchtrittsoffnung 28 für die zu zapfende Flüssigkeit. Der Kolben ist ein zylindrischer Hohlkörper, dessen Mantelwand am inneren Kolbenende eine Eintrittsöffnung 30, und am äußeren Kolbenende eine Austrittsö f- nung 32 für die Flüssigkeit aufweist. Vor dem erstmaligen Zapfen nimmt der Kolben 12 eine in die Laufbuchse 10 eingefahrene Sperrstellung ein (vgl. Fig. 1), in der er die Durchtrittsoffnung 28 der Laufbuchse 10 dicht verschließt. Durch Herausziehen des Kolbens 12 aus der Laufbuchse 10 gelangt die Eintrittsöffnung 30 auf die Höhe der Durchtrittsoffnung 28, und es strömt Flüssigkeit durch das Innere des Kolbens hin zu dessen Austrittsöffnung 32.The bushing 10 has a passage opening 28 in the wall of its cup body for the liquid to be drawn off.
