Definitions
- the present invention relates to a tap head for connection to a barrel, according to the features in the preamble of claim 1.
- the drink itself is provided in a barrel.
- the keg arrives from a brewery or bottling station in a closed state at the point of sale. If the keg is positioned at its intended location, a tap head is placed on the keg / struck and the beverage located in the keg can be extracted.
- the tap head has a Spanngaszutrieitung, so that a clamping gas, for example, provided in a gas cylinder is introduced into the barrel, the barrel is thereby pressurized and the drink comes out of the barrel via a riser.
- the gas used is usually C02.
- Disposable drums are usually made of plastic and not reused after single use, but disposed of. However, there are also plastic returnable barrels.
- the cask is exchanged for a full one. However, the barrel is still under the pressure of the supplied clamping gas.
- Object of the present invention is to show a way that a barrel, especially a disposable keg, is fully vented, it being visible to a user without further examination that the venting function has been performed.
- the tap head is suitable for connection to or for placing on a drum, in particular for a dispensing system, the tap head itself having a tap head body and in the tap head body a clamping gas supply line and a beverage discharge line are formed.
- the tap body is made of a metallic material.
- Zapfkopfoasa can be optional continue to be a ram pipe and coupled to the Zapfkopf Sciences pivot lever. When attaching the tap head to the barrel then the plunger can be moved by the pivot lever in the axial direction.
- the tap head is characterized in that directly on or in the tap head body in the Spanngaszumolishmolustechnisch a 3/2 way valve is formed, which connects with attached and in particular locked tap either the Spanngaszu111technisch from a gas source with the interior of the barrel or the interior the barrel connects with the environment gas-conducting.
- a 3/2-way valve thus has three connections and two switching positions in the context of the invention.
- the 3/2-way valve makes it possible to take two positions or two positions. Either the barrel is gas-conducting connected to the gas source. The dispensing or dispensing operation can thus take place. If the keg is to be replaced or replaced, for example because it is empty or because a technical defect has occurred or a cleaning is required, the 3/2-way valve can be moved to a position where the interior of the keg is gas-conducting with the environment is connected, but at the same time the other clamping gas supply is blocked by the gas source. This ensures that the internal pressure of the drum is vented to the ambient pressure or drops. The barrel could thus be fed without risk of disposal. There is thus no residual pressure in the barrel itself. For example, leaking liquids when removing the tap head are thus avoided. Especially when used on a disposable keg, the disposable keg can be disposed of without residual pressure.
- the 3/2-way valve is directly coupled to the tap head body or integrated into the tap head body increases in particular the operating safety.
- the tap head itself must be removed from the barrel so that a user always has direct access to the 3/2-way valve on the tap head itself.
- the present invention thus also relates to an arrangement which a barrel, a tap head, a gas cylinder and a tap and the respective Components connecting lines includes or the use of a tap head according to the invention with 3/2-way valve and a method for operating a dispensing system.
- the 3/2 way valve is designed in particular as a slide valve or the 3/2 way valve is designed as a rotary valve.
- the 3/2 way valve is particularly preferably coupled either to the tap head body itself, particularly preferably coupled in a form-fitting manner and, in particular, connected by means of screw technology.
- This offers the advantage that the 3/2-way valve can also be retrofitted to already existing dispensing heads or, in the case of wear or defect, the 3/2-way valve can be easily replaced without the entire dispensing head having to be replaced.
- the individual components of the 3/2 way valve may be made of metallic material, for example brass or stainless steel, but also at least partially made of plastic.
- the 3/2 way valve can also be integrally formed and particularly preferably uniform material with the Zapfkopf endeavor itself.
- the 3/2-way valve is thus integrated into the clamping gas supply line of the Zapfkopf emotionss itself. This can be done, for example, by a casting or forging during the production of Zapfkopf stressess.
- the 3/2-way valve designed as a slide valve has been found.
- the 3/2 way valve on an elongated tubular valve seat or valve body.
- On the valve seat a sliding sleeve is arranged.
- the sliding sleeve is preferably designed as a sleeve.
- the valve seat itself is particularly preferably formed laterally projecting from the tap head body. This allows the sliding sleeve on the valve seat to slide back and forth with a particularly simple handling, since the sliding sleeve of several fingers of a user can be embraced and moved. Also, the respective position of the sliding sleeve directly gives an obvious conclusion about the respective state.
- the sliding valve is further designed such that the sliding sleeve has two seals, which are arranged in particular as O-rings in an inner circumferential surface or in grooves of the inner circumferential surface of the sliding sleeve.
- the seals can also be designed as X-ring, piston or rod seal.
- At least two radially directed radial bores are provided in the valve seat, which are arranged spaced from each other in the axial direction.
- the sliding sleeve By sliding the sliding sleeve thus either preferably both radial bores can be covered, thus the radial bores are gas-conducting connected by the gas-tight channel.
- axial displacement of the sliding sleeve can be taken from this a position that a radial bore is exposed with respect to the environment, preferably while the second radial bore is covered. The exposed radial bore can thus vent the internal pressure of the drum to the environment.
- valve seat can also have an axial through-bore. This through hole can also be called a continuous axial bore. So that now two ports are gas-tight separated from each other in the axial direction, a plug is inserted into the through hole. The plug is inserted in particular gastight into the through hole. The plug is pressed in particular in the through hole.
- the plug can also be glued and / or screwed into the through hole.
- the plug thus divides the through-bore into two sections, in particular longitudinal sections. In each section then a radial bore is connected gas-conducting. With the aid of the sliding sleeve, the 3/2 way valve can thus be formed and occupy different positions.
- the through-bore has two longitudinal sections which have a different diameter from each other. A portion of the longer portion of smaller diameter is formed between the radial bores. The plug can thus be inserted through the larger diameter portion of the length in the through hole and then in the smaller diameter length portion, in particular in the part which is located between the two radial bores, are pressed.

- FIG. 10 the tap head with integrally formed 3/2 way valve as
- Figure 1 1 shows a variant of the design of the 3/2-way valve as
- FIG. 1 shows a dispensing head 1 with an attached 3/2 way valve 2 according to the invention.
- the dispensing head 1 has a dispensing head body 3.
- a pivot lever 4 is arranged on the Zapfkopf Sciences 3 itself.
- the pivot lever 4 can move a plunger tube 5 arranged in the tap head body 3 in the axial direction A relative to the tap head body 3.
- a beverage discharge line 6 is formed in the ram tube 5 itself .
- a Spanngaszu111 protest 7 is formed, in which, as shown here, the 3/2 way valve 2 is incorporated by direct arrangement on the Zapfkopfmaschine 3.
- a Druckablassl. Relief valve 8 may be provided to make a further venting function.
- FIGS. 2, 3 and 4 the tap body 3 is shown in an unlocked state.
- the tap head 1 is placed on a barrel 9, it is connected to a not closer, only schematically illustrated barrel head 10 and by downward movement of the pivot lever 4, the plunger tube 5 in the axial direction A in the barrel interior 1 1 or interior of the barrel moves.
- a clamping gas is supplied via the clamping gas supply 7 and enters the barrel interior 1 1 a.
- the internal pressure pi corresponds to the set clamping gas pressure.
- a sliding sleeve 13 has been placed in a transfer position on a slide valve shown here with a tubular or cylindrical valve seat 12 according to FIG. This means the sliding sleeve 13 is moved to the image plane all the way to the right.
- the valve seat 12 itself at least two radial bores 14.1, 14.2 are provided.
- a gas-conducting channel 18 is formed in the 3/2 way valve 2. This is also shown once again in FIG.
- the tap head 1 is initially still sitting on the barrel 9 and thus in the locked position.
- the 3/2-way valve 2 has been switched according to Figure 4 or Figure 7, such that the sliding sleeve 13 is guided to the image plane to the left in a venting position.
- the first radial bore 14.1 still carries the clamping gas, but is due to the pressure-tight formation of the gaseous channel 18 against the environment U sealed.
- the gas tension is thus at the 3/2-way valve 2, but neither enters the barrel interior 1 1, nor to the environment U from.
- the venting is preferably carried out within a short period of time, in particular a few seconds. It can thus move directly after moving the 3/2 way Valve 2 in the venting position, the tap head 1 unlocked and removed from the barrel 9.
- the internal pressure pl then corresponds to the ambient pressure pU.
- two axial bores 19 are made in the valve seat 12, which are mechanically or physically separated from one another in a middle region 20.
- the clamping gas must thus be guided via the radial bores 14.1, 14.2 and the gas-carrying channel 18 from an axial bore 19 in the next axial bore 19.
- the channel 18 is formed radially encircling.
- the 3/2-way valve 2 is produced as a separate component, but is coupled directly to the tap head body 3 by positive locking, in particular due to a screwed connection 21.
- the 3/2-way valve 2 is fixed directly to the tap head 1 itself, so that a user is always also kept to use the 3/2-way valve 2 for venting.
- a second advantage is the separate production possibility of the 3/2-way valve 2 and thus the retrofitting to existing dispensing heads 1 and optionally the interchangeability in the case of maintenance of the 3/2 way valve 2 to the tap head 1 itself.
- FIG. 5 shows an alternative embodiment variant.
- the valve seat 12 of the 3/2-way valve 2 is integrally formed and uniform material with the Zapfkopfmaschine 3 itself. The functionality is otherwise the same.
- Figures 8 and 9 show a sectional view of a tap head 1 analogous to Figures 3 and 4.
- the 3/2-way valve 2 is integrally formed and material uniformly with the tap body 3 itself.
- the 3/2 way valve 2 is designed as a rotary valve.
- the rotary valve can itself be designed, for example, as a ball switching valve, but also as a roller valve.
- the ball 22 or the roller or roller has for this purpose a through hole 23 and a bore 24 extending transversely thereto.
- the through hole 23 can according to Figure 8 in the from a Drum 9 patch position the barrel inside 1 1 with the clamping gas supply 7 connect.
- the through hole 23 blocks the further clamping gas supply through the Spanngaszutex Kunststoff 7. Further, it connects the barrel interior 1 1 with the environment due to the bore 24. This allows venting via an opening 25 take place.
- FIG 10 shows a variant with the valve seat 12, which has a continuous axial bore 26 and a through hole.
- the valve seat 12 is formed in one piece and the same material with the Zapfkopf Sciences 3.
- the valve seat can also be manufactured as a separate component and then coupled to the tap head body 3.
- the through hole 26 has two longitudinal sections 27, 28 with different diameters D1, D2.
- a larger diameter D2 is formed on the image plane on the left.
- a smaller diameter D1 is formed.
- the plug 29 is pressed in particular in a part 31 of the length portion 28 with smaller diameter D1, which is arranged between the radial bores 14.1 and 14.2.
- the continuous axial bore 26 with the two different diameters can be produced. Thereafter, the plug 29 can be inserted from the left side coming into the axial bore 26. Between plug 29 and axial bore 26, a press fit is then formed in this part 31. Furthermore, a connection piece 30 for screwing on a gas line is screwed in the valve seat.
- Figure 1 1 shows an alternative embodiment variant to Figure 6 and 7.
- the seal is not formed as an O-ring, but as a cross-sectionally x-shaped seal. It is an annular seal, which is formed in cross-section x-shaped.
- the x-shaped seal 12 has in cross-section a width B17 which is wider than the bore diameter D14.2 of the radial bore 14.2. Is thus with the sliding sleeve 13 a Intermediate position taken.
- This means that the 3/2-way valve is not open as shown in FIG. 6 or open in FIG. 7. If it is moved from the open in Figure 7 position in a closed position but not to the stop in Figure 6, but in the intermediate position or intermediate position according to Figure 1 1, it could be assumed by the user user due to the position of the sliding sleeve 13, the Slide valve is in a closed position, since he no longer sees the hole 14.2, because it is covered by the sliding sleeve 13.
