Abstract

PCT No. PCT/EP94/01477 Sec. 371 Date Nov. 9, 1995 Sec. 102(e) Date Nov. 9, 1995 PCT Filed May 6, 1994 PCT Pub. No. WO94/26653 PCT Pub. Date Nov. 24, 1994A tap head for beverage containers or barrels includes a tap head plunger which is actuated by a hand lever. A beverage connection is connected to a source of gaseous pressure, such as CO2, and a relief valve is connected to an interior of the tap head with the tap head plunger having a flange. When the hand lever is raised, the relief valve is opened forcefully by way of the tap head plunger through the tap head plunger valve.

Description

Die Erfindung bezieht sich auf einen Zapfkopf für Getränkebehälter oder -fässer, mit einem durch einen Handhebel betätigbaren Zapfkopfstößel, einem Getränkeanschluß, einem Anschluß für ein gasförmiges Druckmittel und einem Behälteranschluß, wobei an den Zapfkopfinnenraum ein Entspannungsventil angeschlossen ist.The invention relates to a dispensing head for beverage containers or kegs, with a dispensing head tappet which can be actuated by a hand lever, a beverage connection, a connection for a gaseous pressure medium and a container connection, a relaxation valve being connected to the interior of the dispensing head.

Derartige Zapfköpfe dienen bekanntlich zur Entnahme von Getränken aus Getränkebehältern oder Getränkefässern, wie Bierfässern. Hierzu wird der Zapfkopf mit den besagten Anschlüssen bei hochgestelltem Handhebel an den Flansch eines Fittings angekuppelt. Der Fitting stellt den in einer Behälteröffnung befindlichen Behälteranschluß dar, der mit einem besonderen bekannten Ventil ausgerüstet ist. Durch Niederdrücken des Handhebels des Zapfkopfes und damit durch Betätigen des Zapfkopfstößels wird ein an diesem Stößel befindlicher Stößelbund gegen eine Gehäusedichtung gepreßt und gleichzeitig wird das Ventil des Fittings geöffnet, so daß ein gasdichter Anschluß gewährleistet ist. Durch den Innenraum um den Zapfkopfstößel strömt Druckgas in den Behälter und fördert das Getränk durch ein mittiges Rohr zu dem Getränkeanschluß und von dort über eine Leitung zur eigentlichen Schankausgabe.Such dispensing heads are known to be used to remove beverages from beverage containers or beverage kegs, such as beer kegs. For this purpose, the tap head with the connections mentioned is coupled to the flange of a fitting with the hand lever raised. The fitting represents the container connection located in a container opening, which is equipped with a special known valve. By depressing the hand lever of the tap head and thus by actuating the tap head tappet, a tappet collar located on this tappet is pressed against a housing seal and at the same time the valve of the fitting is opened, so that a gas-tight connection is ensured. Compressed gas flows through the interior around the tap head tappet into the container and conveys the drink through a central pipe to the drink connection and from there via a line to the actual dispensing device.

Nach dem Entleeren des Behälters wird der Handhebel des Zapfkopfes nach oben hin geschwenkt, so daß die Pressung der Gehäusedichtung aufgehoben wird und der Fitting im Gehäusefaß wieder geschlossen ist.After emptying the container, the hand lever of the dispensing head is pivoted upwards, so that the pressure on the housing seal is released and the fitting in the housing barrel is closed again.

Ein erhebliches Problem besteht darin, daß insbesondere bei höherem Arbeitsdruck im Zapfkopfinnenraum, insbesondere im unteren Hohlraum um den Zapfkopfstößel, ein Gasdruck erhalten bleibt, der bis zu etwa 6 bar reichen kann. Dadurch wird die Gehäusedichtung des Zapfkopfes gegen den Flansch des Fittings gepreßt. Der Nachteil besteht darin, daß der Zapfkopf nur durch Überwindung der von dem Gasdruck erzeugten Haftung vom Flansch gelöst werden kann, was nicht nur einen erheblichen Kraftaufwand, sondern auch eine gewisse Gefahr für die Bedienungsperson bedeutet.A considerable problem is that, especially at higher working pressures in the interior of the dispenser head, in particular in the lower cavity around the dispenser head tappet, a gas pressure is maintained which can reach up to about 6 bar. As a result, the housing seal of the dispensing head is pressed against the flange of the fitting. The disadvantage is that the The dispensing head can only be released from the flange by overcoming the adhesion generated by the gas pressure, which not only means a considerable expenditure of force, but also a certain danger for the operator.

Das zuvor aufgezeigte Problem kann zumindest teilweise bei einem zu Anfang angegebenen Zapfkopf behoben werden, welcher aus dem Dokument EP-A-0 432 650 bekannt ist. Das Druckentspannungsventil ist hier jedoch etwa radial nach außen stehend am Zapfkopfgehäuse angeordnet, so daß der in dem Ventilgehäuse befindliche Ventilstößel in seiner Bewegungsrichtung im wesentlichen senkrecht zur Bewegungsrichtung des Zapfkopfstößels verläuft. Das Druckentspannungsventil dient der Entlüftung des Vorratsbehälters und muß jeweils von Hand, beispielsweise mittels eines Handhebels, betätigt werden. Wenn der Vorratsbehälter entlüftet werden soll, muß die Keg-Armatur geöffnet sein. Es ist allerdings auch denkbar, bei geschlossenem Zustand durch Handbetätigen des Druckentspannungsventils nur den Innenraum des Zapfkopfgehäuses zu entlüften.The problem outlined above can at least partially be remedied in the case of a dispensing head initially specified, which is known from document EP-A-0 432 650. The pressure relief valve is, however, arranged approximately radially outwards on the tap head housing, so that the valve tappet located in the valve housing runs essentially perpendicular to the direction of movement of the tap head tappet in its direction of movement. The pressure relief valve is used to vent the storage container and must be operated by hand, for example by means of a hand lever. If the storage container is to be vented, the keg fitting must be open. However, it is also conceivable to vent only the interior of the dispensing head housing when the pressure relief valve is closed by hand.

Der Erfindung liegt demgegenüber die Aufgabe zu Grunde, unter Beibehaltung der Vorteile der gattungsgemäß vorausgesetzten Anordnung eines Druckentspannungsventils einen Zapfkopf zu schaffen, bei dem automatisch nach jedem Verschlußvorgang eine Druckentspannung im Zapfkopfinnenraum erfolgt, ohne daß es irgendwelcher zusätzlicher Handbetätigungen bedarf.The invention is based on the object to provide a dispensing head while maintaining the advantages of the generic presupposed arrangement of a pressure relief valve, in which pressure relief takes place automatically after each closure process in the interior of the dispensing head without requiring any additional manual operations.

Ausgehend von dem zu Anfang angegebenen Zapfkopf wird die gestellte Aufgabe erfindungsgemäß dadurch gelöst, daß der Zapfkopfstößel mit einem Flansch versehen ist und daß das Entspannungsventil derart ausgebildet und angeordnet ist, daß das Entspannungsventil beim Hochstellen des Handhebels über den sich hierdurch nach oben bewegenden Zapfkopfstößel von dessen Flansch zwangsläufig geöffnet wird.Starting from the dispensing head specified at the beginning, the object is achieved according to the invention in that the dispensing head tappet is provided with a flange and in that the relief valve is designed and arranged in such a way that the expansion valve when the hand lever is raised above the dispensing head tappet which moves upward therefrom Flange is inevitably opened.

Vorteilhafte Ausgestaltungen des Zapfkopfes ergeben sich aus den Unteransprüchen.Advantageous embodiments of the dispensing head result from the subclaims.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung im Schema dargestellt, und zwar zeigen:

  • Fig. 1 eine Seitenansicht auf einen Zapfkopf,
  • Fig. 2 einen Vertikalschnitt durch den Zapfkopf gemäß Fig. 1, wobei das Entspannungsventil um 90° um die Mittelachse in die Bildebene geschwenkt gezeichnet ist, wobei sich der Zapfkopfstößel in der obersten Stellung befindet und
  • Fig. 3 einen Vertikalschnitt gemäß Fig. 2, wobei sich der Zapfkopfstößel in einer mittleren Höhenstellung befindet.
In the drawing, an embodiment of the invention is shown in the diagram, namely:
  • 1 is a side view of a tap head,
  • 2 shows a vertical section through the dispensing head according to FIG. 1, the expansion valve being shown pivoted through 90 ° about the central axis in the image plane, with the tap head plunger in the uppermost position and
  • Fig. 3 is a vertical section according to FIG. 2, wherein the tap head plunger is in a middle height position.

Fig. 1 zeigt eine Seitenansicht eines Zapfkopfes 1 mit einem Anschluß 2 für ein gasförmiges Druckmittel, für das üblicherweise Kohlendioxyd (CO2) verwendet wird. Ferner besitzt der Zapfkopf einen Getränkeanschluß 3 sowie einen Behälteranschluß 8 zur Verbindung mit dem in der Behälteröffnung sitzenden und nicht gezeichneten Fitting. Der Zapfkopf besitzt ferner einen Handhebel 4 zur Betätigung des Zapfkopfstößels 6. Der Handhebel ist in dem Schwenklager 5 gelagert und besitzt beiderseitig des Zapfkopfstößels an sich bekannte Anlenkungen 7. Fig. 1 zeigt ferner die Ansicht auf ein Entspannungsventil 9 in der richtigen seitlichen Stellung, nämlich unter einem Winkel von 90° zu dem Druckmittelanschluß 2.Fig. 1 shows a side view of a dispensing head 1 with a connection 2 for a gaseous pressure medium, for which carbon dioxide (CO 2 ) is usually used. Furthermore, the dispensing head has a beverage connection 3 and a container connection 8 for connection to the fitting seated in the container opening and not shown. The dispensing head also has a hand lever 4 for actuating the dispensing head tappet 6. The hand lever is mounted in the pivot bearing 5 and has articulations 7 known per se on both sides of the dispensing head tappet. FIG. 1 also shows the view of a relief valve 9 in the correct lateral position, namely at an angle of 90 ° to the pressure medium connection 2.

Wie aus den Fig. 2 und 3 ersichtlich ist, besitzt das Entspannungsventil 9 ein Ventilgehäuse 26, welches seitlich an der Zapfkopfgehäusewand 10 befestigt ist. In dem Ventilgehäuse 26 ist ein Ventilstößel 17 mitsamt einem auf ihm sitzenden Flansch 19 und mit einem unteren Ansatz 21 vertikal verschiebbar. Zwischen dem Flansch 19 und einer einstellbaren Schraube 22 ist eine Druckfeder 20 eingesetzt, die normalerweise dafür sorgt, daß der Flansch 19 auf einen unterhalb des Flansches angeordneten Dichtungsring 18 drückt, der dann seinerseits eine Öffnung in der Zapfkopfgehäusewand 10, und zwar im Bereich des Ansatzes 21, abdichtet. Die Verstellbarkeit der im Innengewinde 23 des Ventilgehäuses 26 einschraubbaren Schraube 22 ist derart getroffen, daß der Federdruck entsprechend den Gegebenheiten eingestellt bzw. geregelt werden kann.As can be seen from FIGS. 2 and 3, the expansion valve 9 has a valve housing 26 which is fastened to the side of the tap head housing wall 10. In the valve housing 26, a valve tappet 17 together with a flange 19 seated thereon and with a lower extension 21 can be displaced vertically. Between the flange 19 and an adjustable screw 22, a compression spring 20 is inserted, which normally ensures that the flange 19 presses on a sealing ring 18 arranged below the flange, which in turn then opens an opening in the tap head housing wall 10, in the area of the neck 21, seals. The adjustability of the screw 22 which can be screwed into the internal thread 23 of the valve housing 26 is such that the spring pressure can be adjusted or regulated according to the circumstances.

Zwischen dem Zapfkopfstößel 6 und der Zapfkopfgehäusewand 10 sind zwei Dichtungsringe 11 und 12, in der Praxis sogenannte O-Ringe, vorgesehen. Ferner ist im unteren Teil des Zapfkopfes ein weiterer Dichtungsring 13 eingesetzt. Am unteren Teil des Zapfkopfstößels ist ein mit Gasdurchtrittsöffnungen 15 versehener Flansch 14 angebracht, vorzugsweise aufgeschraubt. Im Bereich der Zapfkopfgehäusewand 10 weist der Zapfkopfstößel 6 im Bereich zwischen den beiden Dichtungsringen 11 und 12 Aussparungen 25 auf, die bei der untersten Stellung des Zapfkopfstößels den Gasdurchtritt nach unten hin gestatten. Mit dem Bezugszeichen 16 ist der Zapfkopfinnenraum bezeichnet, an den das Entspannungsventil 9 angeschlossen ist. Die Wirksamkeit des Entspannungsventils wird noch dadurch erhöht, daß dann der untere Ansatz 21 etwa einen dreieckigen oder sternförmigen Querschnitt aufweist.Two sealing rings 11 and 12, in practice so-called O-rings, are provided between the tap head tappet 6 and the tap head housing wall 10. Furthermore, a further sealing ring 13 is used in the lower part of the tap head. A flange 14 provided with gas passage openings 15 is attached, preferably screwed, to the lower part of the tap head tappet. In the area of the tap head housing wall 10, the tap head plunger 6 has cutouts 25 in the area between the two sealing rings 11 and 12, which allow the gas to pass downward when the tap head plunger is in the lowest position. The reference numeral 16 denotes the interior of the dispensing head to which the expansion valve 9 is connected. The effectiveness of the expansion valve is further increased by the fact that the lower extension 21 then has approximately a triangular or star-shaped cross section.

Die Wirkungsweise ist im wesentlichen folgende.The principle of operation is as follows.

Bei der Schwenkbewegung des Handhebels 4 nach oben hin, wird der Zapfkopfstößel 6 in die oberste Stellung gemäß Fig. 2 gebracht. Dabei wird das Entspannungsventil 9 automatisch betätigt, und zwar dadurch, daß der Flansch 14 gegen das untere Ende des Ansatzes 21 drückt, so daß damit das Entspannungsventil geöffnet wird und der Gasdruck aus dem Zapfkopfinnenraum 16 durch die Zwischenräume in den Ansatz 21 und durch den entstehenden Gasaustrittsspalt 24 auf der Unterseite des Dichtungsringes 18 nach außen entweichen kann.When the hand lever 4 pivots upwards, the tap head plunger 6 is brought into the uppermost position according to FIG. 2. The expansion valve 9 is actuated automatically, in that the flange 14 presses against the lower end of the extension 21, so that the expansion valve is opened and the gas pressure from the interior of the dispenser 16 through the gaps in the extension 21 and through the resulting Gas outlet gap 24 on the underside of the sealing ring 18 can escape to the outside.

Fig. 3 zeigt eine mittlere Höhenstellung des Zapfkopfstößels 6. Bei einer nicht gezeichneten unteren Stellung, in der die beschriebene öffnung des Gefäßes erfolgt, drückt der Flansch 14 gegen den Dichtungsring 13. In einer der besagten Mittelstellungen und in der untersten Stellung des Zapfkopfstößels 6 ist das Entspannungsventil 9 durch Druck der Druckfeder 20 ständig geschlossen. Das automatisch wirkende Entspannungsventil 9 erfüllt aber auch noch eine Sicherheitsfunktion, nämlich dann, wenn ein unzulässig hoher Überdruck im Getränkebehälter oder bei der Druckgaszufuhr entsteht. Die Druckfeder 20 kann mittels der in der Praxis allerdings fixierten Schraube 22 so eingestellt werden, daß das Entspannungsventil bei einem solchen unzulässig hohen Druck automatisch öffnet.3 shows a middle height position of the tap head plunger 6. In a lower position, not shown, in which the described opening of the vessel takes place, the flange 14 presses against the sealing ring 13. In one of the said middle positions and in the lowest position of the tap head plunger 6 the expansion valve 9 is constantly closed by pressure of the compression spring 20. That automatically Acting expansion valve 9 also fulfills a safety function, namely when an impermissibly high excess pressure arises in the beverage container or when the compressed gas is supplied. The compression spring 20 can be adjusted by means of the screw 22, which is however fixed in practice, in such a way that the relief valve opens automatically at such an impermissibly high pressure.
