Flows into barrel 25 from.

When the cock (not shown) that closes the beverage extraction passage 31 of the dispensing head 27 is opened, the beverage such as beer filled in the barrel 25 flows out due to the pressure of gas such as carbon dioxide. It flows into the outflow passage 15 from the lower end opening of the passage 15, flows through it, flows from the upper end opening of the outflow passage 15 into the beverage takeout passage 31 at the center of the pressing member 30, and flows there through to be provided at the end thereof. The beverage is taken out into a container (not shown) such as a jug from the beverage taking-out port.

In the barrel valve 1 according to this embodiment configured as described above, the fixing member 2 is loosened in order to take out a beverage such as beer and remove it from the mouth 26 of the barrel 25 that has become empty. In this case, a series of gas vent holes 9 for communicating the inside and outside of the barrel 25 are formed at a portion corresponding to the through hole 8 formed between the first seal member 5 and the fixed member 2 and the mouth portion 26. Gas such as carbon dioxide gas remaining in the barrel 25 is discharged to the outside of the barrel 25 through the vent hole 9.

That is, when the fixing member 2 is loosened, the barrel 25
When the pressure of the gas such as carbon dioxide gas remaining inside acts on the first seal member 5, the pressure causes the first seal member 5 to move.
Although the rubber portion 7 of the first seal member 5 tends to expand and deform outward in the radial direction, since the metal ring 6 is embedded on the outer peripheral side of the rubber portion 7 of the first seal member 5, Excessive deformation to one side is prevented, the entire outer peripheral side of the first seal member 5 is in close contact with the inner peripheral side of the mouth portion 26, and a part thereof enters between the fixing member 2 and the mouth portion 26 and It is possible to surely form a series of gas vent holes 9 that communicate the inside and outside of the barrel 25 on the outer peripheral side of the first seal member 5 without sealing the spaces between them.

Therefore, when the fixing member 2 is removed from the mouth portion 26, the gas pressure remaining in the barrel 25 acts on the fixing member 2 at once, and the constituent members such as the fixing member 2 and the tubular member 10 are opened. Even if a child or a drunk person mischievously touches the barrel valve 1 of an empty barrel that has been stored outdoors, it is blown away from 26 and hits the body of a child or the like and is injured. There is no such a case, the safety is remarkably improved, and the management when storing the empty barrel becomes easy. Further, when the gas in the barrel 25 is discharged to the outside through the gas vent hole 9, exhaust sound can be generated by the orifice effect of the gas vent hole 9, so that sound is used as an “alarm sound”. By doing so, it is possible to confirm whether or not the gas has been discharged from the barrel 25, which further enhances safety.

[0040]

As described above, according to the present invention, when the fixing member is removed from the mouth portion of the barrel, the barrel is provided at the portion corresponding to the through hole between the fixing member and the first sealing member and the mouth portion. A series of gas vent holes communicating between the inside and the outside can be formed, and the gas such as carbon dioxide gas remaining in the barrel can be discharged to the outside of the barrel through the gas vent holes. Therefore, when the fixing member is removed from the mouth of the barrel, the pressure of the gas such as carbon dioxide gas remaining in the barrel does not blow off the constituent members such as the tubular member from the mouth, The blown components do not hit the body and injure them, or the objects around them are not destroyed, which greatly improves safety and facilitates management when storing empty barrels. Becomes Also, when the gas in the barrel is exhausted to the outside through the gas vent hole, exhaust sound can be generated by the orifice effect of the gas vent hole, so that sound is called "alarm sound".
By using it as, it will be possible to confirm whether or not the gas has been discharged from the barrel, which further enhances safety.
