A check valve (fluid on-off valve device) capable of attaining high sealability in either case where a differential pressure is high or low, comprises a valve body assembly (valve body) contacting and separating from a valve seat portion for communicating and blocking a fluid passage. The valve body assembly comprises a valve body, a low-pressure seal portion constituted out of soft material and a high-pressure seal portion constituted out of harder material than the low-pressure seal portion. In blocking a fluid passage, when a differential pressure between an upstream path and a downstream path in the fluid passage is relatively low, the low-pressure seal portion comes into close contact with a protrusion to block the fluid passage, while when the differential pressure is relatively high, the low-pressure seal portion is compressively deformed by the differential pressure and the high-pressure seal portion comes into close contact with the valve seat body, thus blocking the fluid passage.

Fluid on-off valve device

Disclosed is a seal structure of a high-pressure tank capable of properly securing seal efficiency. The seal structure of the high-pressure tank includes a plurality of seal members that have mutually different seal properties and that are installed between a ferrule of the high-pressure tank and a valve body attached to the ferrule. One of the plurality of seal members has low temperature resistance, and the other has high temperature resistance. A first seal member is an O-ring formed of butyl rubber or silicone. A second seal member is an O-ring formed of EPDM. Furthermore, the two O-rings are different in gas permeability from each other. This seal structure can be applied between the ferrule and the valve body, in addition, between the ferrule and a liner, between the ferrule and a shell, and between the valve body and the shell.
