Tap head having a 3/2-way valve
The disclosure relates to a tap head for connecting to a keg for a bar system, the tap head having a tap head body, and a pressurization-gas supply line and a beverage removal line being formed in the tap head body, such that a 3/2-way valve is formed directly on or in the tap head body in the pressurization-gas supply line, which 3/2-way valve connects either the pressurization-gas supply line from a gas source to the interior of the keg or connects, in a gas-conducting manner, the interior of the keg to the environment.
1. A tap head for connecting to a keg in a bar system, the tap head comprising:
a tap-head body;
a pressurization-gas supply line;
a beverage draw line in the tap-head body; and
a 3/2-way valve in the pressurization-gas supply line in the tap-head body,
wherein the 3/2-way valve is configured to connect the pressurization-gas supply line from a gas source to an interior chamber of the keg or to connect the interior chamber of the keg to an environment in a gas-conducting manner, and
wherein the 3/2-way valve has a valve seat on which a sliding sleeve is arranged, and the valve seat laterally juts from the tap-head body.
2. The tap head according to claim 1 , wherein the 3/2-way valve comprises a slide valve.
3. The tap head according to claim 1 , wherein the 3/2-way valve is coupled to the tap-head body with threaded screw fitting.
4. The tap head according to claim 1 , wherein the 3/2-way valve has a valve seat comprising the same material as the tap-head body.
5. The tap head according to claim 1 , wherein
the sliding sleeve has two gaskets glidably mounted on the valve seat, and
a gas-tight channel is between the two gaskets.
6. The tap head according to claim 1 , wherein
the valve seat has at least two radial boreholes aligned in a radial direction, and arranged axially spaced apart relative to one another, and
by displacement of the sliding sleeve, both of the radial boreholes are covered.
7. The tap head according to claim 6 , wherein
the valve seat has two axial boreholes physically distanced from one another within a central region of the sliding sleeve, and
the axial boreholes are connected to the radial boreholes in a gas-conducting manner.
8. The tap head according to claim 6 , wherein
the valve seat has a through-going axial borehole,
a stopper is inserted between the two radial boreholes, and
the stopper divides the through-going axial borehole into two longitudinal portions.
9. The tap head according to claim 8 , wherein
the two longitudinal portions have diameters that differ from one another, and
a part of the longitudinal portion having the smaller diameter is between the two radial boreholes.
10. The tap head according to claim 1 , wherein
the sliding sleeve has two O-rings glidably mounted on the valve seat, and
a gas-tight channel is between an outer casing surface of the valve seat and an inner casing surface of the sliding sleeve.
11. The tap head according to claim 1 , wherein
the valve seat has at least two radial boreholes aligned in a radial direction, and arranged axially spaced apart relative to one another, and
by displacement of the sliding sleeve, one of the radial boreholes is exposed to the environment.
12. The tap head according to claim 1 , wherein
the sliding sleeve has two gaskets glidably mounted on the valve seat, and
a gas-tight channel is between an outer casing surface of the valve seat and an inner casing surface of the sliding sleeve.
