Claims

[Claims for Utility Model Registration] Inside the tube-shaped main body, the tip of which is connected to the valve outlet of the gas container and the base end of which is connected to gas supply equipment, there is a tip enlarged diameter portion and a tip enlarged diameter portion. A gas flow hole having an inflow side and an outflow side step formed by the part □ is bored, and a sliding closing member with a gas flow passage formed from the side surface near the distal end to the proximal end surface has a large diameter at the distal end. is provided in the main body so that a part thereof is movably located within the enlarged diameter part at the distal end, and a sliding cylinder part thereof is slidably inserted into the gas flow hole, and the slider is disposed within the gas flow hole. A biasing member is provided that biases the closing member toward the gas container with a predetermined elastic force, and the pressure difference between the gas pressure flowing into the main body and the gas pressure flowing out from the main body reaches a predetermined pressure. When the sliding closing member moves toward the proximal end of the main body, the large diameter portion of the distal end locks into tight contact with the stepped portion on the outflow side of the enlarged diameter portion of the distal end, thereby preventing release of high pressure gas. In the gas release preventer, the large diameter portion at the tip is formed into a solid cylindrical shape, and a bottomed cylindrical cylinder member having a small hole for gas circulation passing through the peripheral wall in the axial direction is provided inside the cylinder member. A gas release preventer characterized in that the large diameter portion of the cylindrical tip is fixed within the enlarged diameter portion of the tip of the gas distribution hole in a loosely fitted manner.
