Safety system for beer dispensing circuit - includes bulk storage tank and safety valves on dispensing nozzle and pump

摘要

The beer dispensing system for hotels, bars etc. uses a large tank delivered by a vehicle to the premises. The tank is divided into compartments. A line is connected to gas cylinders to apply pressure to the contents. The discharge line from the tank includes a pump with a safety valve permanently connected in parallel to it. It is then connected to an air separator, a flowmeter and a sight glass before joining a dispensing line wound onto a drum, with a dispensing nozzle at its end. This nozzle incorporates a safety valve which is normally closed against the pressure of the flowing beer. The safety valve on the pump can be adjusted, and after it is opened the pump is operated in a closed circuit.
