| description | The utility model provides a vacuum fresh keeping barrel for draught beer and soda pop beverages. The utility model is characterized in that the top of the fresh keeping barrel is provided with an inflation valve which can be opened and closed with an inner cavity of an inner casing, and the inner casing is also provided with a pressure stabilizing valve. When the beer is filled, the compressed air can be filled in the cavity of the inner casing by the inflation valve. Thus, the cavity of the inner casing forms a back pressure cavity which has the pressure about 0.1MPa, the beer filling pressure is about 0.12MPa, and the pressure difference of the back pressure and the beer filling pressure is only about 0.02MPa (less than 0.05MPa). Therefore, the gas of the CO2 can not get out in the process of filling the beer, and thus, the utility model can ensure that the beer can not contact the air all along in the processes of beer filling, beer storage and beer discharge. As a consequence, the utility model truly realize vacuum refresh preservation. |
