    摘要： This high-pressure tank includes a resin liner constituting a hollow fluid filling part, a ferrule including a supply/discharge port which communicates with an internal space of the liner and a flange part which protrudes outward in a radial direction from a circumferential region of the supply/discharge port and abuts on the liner, and a reinforcing layer made of a fiber reinforced resin attached to cover across the liner and an outer circumferential surface of the flange part, in which a discharge hole allowing a gap between abutting surfaces of the flange part and the liner to communicate with an inside of the supply/discharge port and discharging a fluid accumulated between the liner and the reinforcing layer to the supply/discharge port is provided in the ferrule, and a trap groove surrounding a circumferential region of the discharge hole is provided on at least any one of the abutting surface on the flange part side and the abutting surface on the liner side.

    摘要： The invention relates to a head (2) for a tank (1) used to store pressurised gas, comprising, in an integrated manner: at least two components (131, 132) for treating, distributing and/or shutting off the gas; an upstream connector (20) suitable for being removably attached in a boss (4) of the tank (1); and downstream outlet pipes (211, 212) suitable for connecting the head (2) to any system using said gas by means of the aforementioned components (131, 132). According to the invention, each component (131, 132) comprises at least two sealing devices (141, 142) defining an intermediate space therebetween, and at least one pipe (12), called tapping pipe, connects each of the intermediate spaces and a common space (8) into which ail the tapping pipes (12) emerge, with an orifice (15) providing a connection between the common space (8) and a gas-detection device (16).

    摘要： The high pressure tank includes a tank body, a valve, and a handle unit. The valve includes a first body provided with a first housing hole and a first communication hole communicating with the first communication hole, a second body provided with a second communication hole communicating with the first housing hole and a second housing hole communicating with the second communication hole, a connector portion provided with a through hole communicating with the second housing hole, a second valve disc blocking the communication between the through hole and the second housing hole and allowing the communication between the through hole and the second housing hole by the pushing force of the pushing pin, and a handle portion that can be fitted into the handle receiving groove on the gas supply target side. The first valve disc opens and closes with an operation of twisting the handle unit.
