As shown in FIG. 1, the present embodiment provides an air inlet valve for a beer barrel, which comprises a barrel plug 100 and an air storage barrel 200. The barrel stopper 100 serves as a cap stopper for the beer barrel, and is used for sealing the beer barrel and placing the gas storage barrel 200 inside the beer barrel, and may be made of rubber and/or plastic. The shape of the gas receiver 200 is not exclusive as long as it defines a cavity capable of storing gas, and it is formed with a gas discharge hole for discharging gas into the beer barrel, the gas receiver 200 is connected to the lower portion of the bung 100 and has an inner cavity for storing gas, and the gas receiver 200 may be integrally formed with the bung 100 or detachably connected to the bung 100. In order to control the opening and closing of the vent hole from the outside, the air intake valve of the beer barrel of the embodiment further comprises a transmission shaft 300, a knob 400 connected to the upper part of the transmission shaft 300, and a stopper connected to the lower part of the transmission shaft 300, wherein a shaft hole 110 is formed in the barrel plug 100, the transmission shaft 300 penetrates through the shaft hole 110 and blocks the shaft hole 110, the knob 400 can be detachably connected with the transmission shaft 300, the stopper is driven by the transmission shaft 300 to rotate together, and the vent hole is opened and closed by the rotation of.

In order to store a sufficient amount of gas, the gas receiver 200 may be filled with compressed gas (such as carbon dioxide, nitrogen or a mixture of carbon dioxide and nitrogen), so as to avoid too fast discharge of the gas in the gas receiver 200, in this embodiment, a flow guiding structure is further formed inside the gas receiver 200, and when the vent hole is opened, the flow guiding structure is used to guide the gas to flow in a circuitous manner in the gas receiver 200, so as to slow down the discharge of the gas, thereby ensuring that a proper amount of gas enters the beer barrel. As shown in fig. 4, in particular, the flow guiding structure includes a first flow guiding pipe 230 extending upward from the bottom of the gas holder 200, and a second flow guiding pipe 240 disposed below the exhaust hole and extending from the sidewall of the gas holder 200 to the inside of the first flow guiding pipe 230. A first narrow gap is formed between the top end of the first flow tube 230 and the sidewall of the second flow tube 240. The first draft tube 230 and the second draft tube 240 divide the inner cavity of the gas storage barrel 200 into three parts, namely, a first chamber a between the lower side of the inner wall of the gas storage barrel 200, the upper side of the outer wall of the second draft tube 240 and the outer wall of the first draft tube 230; a second chamber B between the inner wall of the first draft tube 230, the lower side of the outer wall of the second draft tube 240 and the bottom surface of the gas storage barrel 200; and a third chamber C between the inner wall of the second guide pipe 240 and the upper side of the inner wall of the air storage barrel 200. The vent is in direct communication with the third chamber C. After the exhaust hole is opened, the gas in the third chamber C is firstly exhausted through the exhaust hole, then the gas in the second chamber B enters the third chamber C from the bottom of the second flow guide pipe 240, and the gas in the first chamber a enters the second chamber B through the first narrow slit along the first flow guide pipe 230, as shown by the arrow in fig. 4. By using the flow guiding structure formed by the first flow guiding pipe 230 and the second flow guiding pipe 240, the gas in the first chamber and the second chamber can not directly flow towards the exhaust holes after the exhaust holes are opened, and the gas can be effectively prevented from being exhausted too fast by using effective flow guiding and guiding to flow in a roundabout manner. In the present embodiment, the inner diameter of the second flow guide pipe 240 is gradually increased from bottom to top. When the gas flows from the second flow guide pipe 240 to the exhaust hole, the gas flow rate is slowed down because the inner diameter of the second flow guide pipe 240 is gradually enlarged from bottom to top, which can slow down the gas exhaust speed.

According to the beer storage barrel, the gas storage barrel 200 is arranged in the beer barrel, when beer in the beer barrel cannot be discharged, clean gas (such as nitrogen and carbon dioxide) in the gas storage barrel 200 is discharged into the beer barrel, so that the beer quality is effectively guaranteed while the beer in the beer barrel smoothly flows out, the problems of shortened beer preservation period, reduced taste and easiness in quality deterioration are solved, particularly when the gas storage barrel 200 is filled with nitrogen, the nitrogen discharged into the beer barrel through the gas storage barrel can rapidly increase beer foam, the beer foam is pure, fine, white and rich, cups are hung for a long time, and the taste of the beer is smooth and refreshing. Specifically, the gas storage barrel 200 is connected to the lower part of the barrel plug 100, the barrel plug 100 is used for sealing a beer barrel, the gas storage barrel 200 is placed in the beer barrel, in order to control the timely discharge of gas in the gas storage barrel 200, the shaft hole 110 is formed in the barrel plug 100 for installing the transmission shaft 300, the knob 400 is installed on the upper part of the transmission shaft 300, the stop block is installed on the lower part of the transmission shaft 300, the stop block is driven by rotating the knob 400, and the opening and closing of the gas outlet hole are implemented by utilizing the rotation of the stop block. Meanwhile, the flow guide structure is arranged in the gas storage barrel 200, so that gas can be guided to flow in a roundabout manner by utilizing effective flow guide and flow control after the exhaust holes are opened, the gas can be effectively prevented from being exhausted too fast, and the beer can generate fine and soft foam.

Preferably, the second flow guide pipe 240 extends to the bottom of the first flow guide pipe 230 to form a second narrow slit with the bottom of the gas receiver 200. And the gas is guided through the second narrow slit, so that the gas flow flowing into the third chamber C is further reduced, and the gas discharge is slowed down.

As shown in FIG. 4, the top end of the first flow conduit 230 is disposed near the middle of the second flow conduit 240. The height of the first flow conduit 230 can affect both the gas flow path and the first slot area. When the height of the first draft tube 230 is too high, although the gas flow path becomes long, the gas flow rate increases due to the increase of the first slit area; when the height of the first draft tube 230 is too low, the first slit area can be reduced, but the flow path of the gas in the first chamber a and the second chamber B becomes short; the slow discharge of gas is affected by both too high and too low a height of the first draft tube 230. When the top end of the first guide pipe 230 is disposed near the middle of the second guide pipe 240, the matching between the gas flow path length and the first narrow slit area can be ensured, so as to effectively avoid the gas from being discharged too fast.

In order to improve the sealing performance between the transmission shaft 300 and the shaft hole 110, in one embodiment, a sealing structure may be disposed between the transmission shaft 300 and the shaft hole 110, and specifically, reference may be made to a sealing structure in the existing shaft hole 110 mounting technology, which is not described in detail herein.
