Then, when the fixing member 2 is loosened to take out the beverage such as beer and remove the barrel valve 1 from the opening 26 of the empty barrel 25, the inner peripheral surface of the opening 26 and the first seal member are removed. A series of gas vent holes 9 communicating with the inside and outside of the barrel 25 are formed at portions corresponding to the through holes 8 formed between the barrel 5 and the outer peripheral surface of the fixing member 2. Gases such as carbon dioxide gas remaining inside are discharged out of the barrel 25.

That is, when the fixing member 2 is loosened, the pressure of the gas such as carbon dioxide remaining in the barrel 25 becomes the first pressure.
When acting on the seal member 5, the first seal member 5 is expanded and deformed by the pressure. However, since the outer peripheral side of the first seal member 5 is provided with the concave portion 7 penetrating in the axial direction, 1 The entire outer peripheral surface of the sealing member 5 is
The upper surface and the lower surface of the first seal member 5 can be communicated in the axial direction at a portion corresponding to the recess 7 without being in close contact with the inner peripheral surface. A series of gas vent holes 9 communicating the inside and outside can be reliably formed.

On the other hand, even when the first seal member 5 is mounted in an inverted state and the inner and outer peripheral surfaces are exchanged, the recess 7 is also provided on the inner peripheral surface of the first seal member 5. Therefore, the upper and lower surfaces of the first seal member 5 can be communicated with each other in the axial direction via the recessed portions 7, and the first seal member 5
A series of gas vent holes 9 communicating the inside and outside of the barrel 25 can be reliably formed on the outer peripheral side of the barrel.

Therefore, even if the fixing member 2 is loosened in order to remove the barrel valve 1 from the mouth 26 of the barrel 25,
Since gas such as carbon dioxide remaining in the barrel 25 can be discharged to the outside of the barrel 25 through the gas vent hole 9, the barrel 25 can be discharged.
The components such as the fixing member 2 and the tubular member 10 are not blown off from the opening 26 by the pressure of the gas such as carbon dioxide gas remaining inside.

As a result, even if the empty barrel 25 is stored outdoors or the like, and the fixing member 2 is loosened due to mischief by a child or a drunkard, the fixing member 2 or the like may be used. The constituent members are not blown out of the mouth 26, and do not hit the body of a child or the like to cause unexpected injuries or hit surrounding objects to break the objects, thereby greatly improving safety. , The management when storing the barrel 25 becomes easy.

When gas such as carbon dioxide gas in the barrel 25 is discharged to the outside of the barrel 25 through the gas vent hole 9, a discharge sound can be generated by the orifice effect of the gas vent hole 9. By using the alarm sound, it is possible to easily and reliably check whether or not gas has been discharged from the barrel 25.

[0047]

According to the present invention, as described above, when the fixing member is loosened to remove the barrel valve, the opening corresponding to the opening between the mouth and the fixing member and the first sealing member can be accommodated. A series of gas vent holes communicating between the inside and the outside of the barrel can be formed at the portion where the gas flows, and gas such as carbon dioxide remaining in the barrel can be discharged outside the barrel via the gas vent holes. Therefore, the components such as the fixing member and the tubular member are blown off from the mouth by the pressure of the gas such as carbon dioxide gas remaining in the barrel, and it hits the body to cause unexpected injury or hits the surrounding objects to cause the object. There is no such thing as breaking, and the safety can be remarkably improved, and the management when storing empty barrels becomes easy. Also, when discharging gas such as carbon dioxide remaining in the barrel through the gas vent hole to the outside of the barrel, an exhaust sound can be generated by the orifice effect of the gas vent hole. Utilization makes it possible to easily and reliably confirm whether or not gas has been discharged from the barrel. Therefore, safety can be further improved. Further, by providing the outer peripheral surface and the inner peripheral surface of the first seal member with depressions, even if the first seal member is mounted in an inverted state and the inner and outer peripheral surfaces are replaced, the depression of the inner peripheral surface is formed. The portion allows the upper and lower surfaces of the first seal member to communicate with each other. Therefore, a through hole can be reliably formed between the mouth, the fixing member, and the first seal member, and a series of gas vent holes that communicate the inside and outside of the barrel with a portion corresponding to the through hole can be reliably formed. The gas such as carbon dioxide remaining in the barrel can be reliably discharged to the outside of the barrel via the gas vent hole, so that the nerve is not used for mounting the first seal member, and the barrel is not used. It has excellent effects such as easy attachment of the valve for use to the mouth of the barrel.
