[0002] The existing back-pressure vacuum fresh-keeping barrel (ZL01243418.3) adopts the air bag in the liner and the back-pressure wine filling technology in structure, so that the wine barrel is evacuated through the wine inlet and outlet valve before leaving the factory, and the air is connected to the atmosphere when the wine is released. The air bag is close to the wine surface, which not only blocks the contact between the air and the wine, but also makes the CO in the wine 2 It cannot overflow, so that the wine is always kept in an anaerobic state, thereby maintaining the original flavor and freshness of the beer for a long time, and the beer poured in is liquor instead of foam, which not only saves a lot of fresh beer, but also makes the beer Drinking, long-distance storage, transportation and sales are all greatly benefited, but the existing technology is structurally equipped with three valves, a pressure stabilizing valve, a pipeline valve and an air intake valve, on the chassis of the barrel mouth, so not only the process and the wine filling operation are complicated, Moreover, the cost is high, and it is difficult to realize normal filling and simultaneous multi-barrel filling

Embodiment Construction
[0013] The present invention has a barrel body 1 including an inner tank 11, an outer barrel 10 and an insulating layer 2 therebetween, an air bag 3 in the inner bag 11 that prevents the wine liquid from contacting the air, an air inlet and outlet device communicated with the air bag 3, and a wine inlet and outlet valve 4 , the air inlet and outlet device is that only one quick connector seat 8 for the air circuit is set on the chassis of the flange sleeve 9 in the barrel neck. The disc-shaped flange sleeve 9 is pressed on the plane at the end of the connecting sleeve 7. There is a thread M on the outer diameter of the end of the connecting sleeve 7 that welds the inner barrel and the outer barrel together. The flange sleeve 9, The sealing ring 6 and the mouth of the air bag 3 are compressed on the end plane of the connecting sleeve 7 . The above-mentioned pneumatic quick connector seat 8 is the main body of commercially available pneumatic quick connector products.
