Description

[Detailed explanation of the invention] This invention was developed when taking draft beer out of the draft beer refrigerator.
The present invention relates to a gas outlet valve device in a conventional carbon dioxide gas cartridge connected to a pressure reducing valve, which utilizes the pressure of carbon dioxide gas.

Although this carbon dioxide gas cartridge is small and extremely easy to handle, it is necessary to attach the carbon dioxide gas cartridge to the side wall of the draft beer cooler via a pressure reducing valve to easily and reliably extract the carbon dioxide gas. It is something to do.

Hereinafter, one embodiment of this invention will be described in detail with reference to the accompanying drawings.

1 is a draft beer cooler, and a pressure reducing valve body 2 is attached to the side wall thereof.

The main body of the pressure reducing valve body 2 protrudes to the outside of the cooler 1, and the mounting portion 3 is inserted into a mounting hole drilled in the side wall of the cooler 1 to be mounted.

Incidentally, since this installation is done through the bushing 7 and the screws 8, there is no possibility that the pressure reducing valve body 2 will turn accidentally.

Further, the end of the mounting portion 3 projects inside the cooler 1, and a gas jetting valve body 4 is slidably fitted inside this projecting portion.

The rear end of this jetting valve body 4 is formed into a tapered part 9, and in order to allow the tapered part 9 to freely close and release the end face of the gas conduit 5 of the mounting part 3, there is a gap between the end face and the end face. It is designed so that you can immerse yourself in it and leave it.

Further, it goes without saying that the valve body 4 is formed into a hollow 10 and has an open front surface. Immediately before the tapered portion 9, a part of the side wall of the valve body 4 is opened 11, and this opening is opened. When the valve body 4 is separated from the end face of the gas conduit 5, the gas passage can be communicated through the gas passage 11.

Also; this valve body 4 is fitted with a gland nut 6,
The tip of this gland nut 6 is made to protrude inwardly, and this protruding part 12 is made to protrude to the outside of the valve body 4.
It is also clamped between the stop links 14, and by screwing the gland nut 6, the valve body 4 can be moved to the left in FIG.

Of course, it is a matter of course that the threaded portion carved on the inner surface of the gland nut 6 meshes with the threaded portion carved on the outside of the protrusion 12 of the mounting portion 3 to perform the screwing operation.

The left and right sliding movement of the valve body 4 based on the spiral turn of the ground nut 6 is sufficient if the space 4' is provided, and the valve body 4 can be slid left and right between this space 14' to perform the valve action. It is intended to do the following.

In addition, the reference numeral 15 in the figure is a heat insulating material, which is interposed between the outer box 16 and the inner box 17 of the cooler 1 to form the main body of the cooler.

Further, 18 is a carbon dioxide gas cartridge, which is screwed into a threaded piece 19 at the tip of the pressure reducing valve 2.

At this time, the head of the cartridge 18 is opened with the opening needle 20 protruding from the center of the screw piece 19, and the CO2 in the cartridge 18 is released from the opening through the opening needle 20. The gas is introduced into the pressure-reducing valve body 2 through the notch 20, and sent out from the valve body 4 through the gas conduit 5 of the mounting part 3, and the draft beer is taken out by this gas pressure.

The pressure reducing valve 2 itself is a general type, and the only difference is the opening needle 20, so a description of the pressure reducing valve 2 itself will be omitted.

Since this invention relates to the configuration described above, the sealing state of the CO2 cars 1 to 18 screwed together with the pressure reducing valve 2 is broken, and the CO2 is opened. CO2 flows into the interior and is constantly sent through the gas conduit 5' of the attachment part 3 from the force ejection valve body 4.

Therefore, open the door of cooler 1, insert your hand inside,
By screwing the gland nut 6, the gas ejection valve body 4 is separated from the end face of the gas conduit 5, and the gas flow path is communicated.

Since this valve body 4 is connected to the beer container through a hose, when the take-out cock of the draft beer cooler 1 is opened, the pressure of the CO2 is applied inside the beer container, and the beer container is opened. The draft beer in the container can be taken out from the tap.

Therefore, when the gas pressure of C02 is not used and the extraction or sale of draft beer is stopped, the ground nut 6
Screw it in the opposite direction to the above! In some cases, the tapered portion 9 at the rear of the valve body 4 fits into the end face of the gas guide 5 and comes into close contact with the valve body 4, thereby closing the gas passage.

Therefore, for safety, it will be more reliable if the set screws of the ground nuts 1 to 6 are tightened.

As described above, the present invention makes it possible to easily and securely take out and close CO2 by the sliding action of the valve body 4 for ejecting force, and to
This is a device with practical value, as it allows the use of 02 cartridges extremely effectively.
