ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a device for cleaning a tapping head arrangement for tapping beverages pressurized under gas, the device being intended for refitting any desired tapping head.
2. The Prior Art
Many different proposals have been made in the past for cleaning tapping head arrangements that can be connected to beverage barrels. The known cleaning devices are generally conceived so that they are directly connected to the tapping head arrangement or to the tapping head.
The present invention is based on the problem of providing a device for cleaning a tapping head arrangement that can be refitted on any desired type of tapping head at a later time.
SUMMARY OF THE INVENTION
The present invention proposes to solve the problem by providing a device for cleaning a tapping head arrangement which comprises:
(a) a housing;
(b) a first connection for a cleaning agent on the housing;
(c) a second connection for a beverage on the housing;
(d) a tubular attachment on the housing for insertion in a tapping tappet of the tapping head arrangement;
(e) a tubular cleaning agent feed line arranged in the attachment;
(f) an actuation housing connected to the cleaning agent feed line;
(g) first and second non-return safety valves disposed at a lower end of the cleaning agent feed line and arranged in the actuation housing;
(h) an actuating pin for actuating the safety valves mounted on a lower portion of the cleaning agent feed line so that with the tapping tappet of the tapping head arrangement in the cleaning position, the tapping tappet presses the actuating pin against the second non-return safety valve for opening the feed of cleaning agent, and with the tapping tappet in the tapping position, the second non-return valve blocks the feed of cleaning agent from the beverage line of the tapping head arrangement and the first non-return safety valve blocks the beverage from entry into the cleaning agent feed line.
The device as defined by the invention has the important advantage of being able to be inserted in a simple manner in the tapping tappet of any desired type of tapping head, and be functionally reliable in the inserted condition. This is substantially accomplished in that in the two positions “cleaning position” and “tapping position”, any penetration of the respective liquid, for example of the beverage or the cleaning liquid, into zones not intended for such penetration is made impossible.
Special embodiments of the device as defined by the invention are discussed below.
