  • Publication number: 20110210131
    Abstract: In a screw structure of a high-pressure tank, there is an issue in that the strength of the screw section declines each time the screw section is used, and therefore an object of the present invention is to provide a tank having a structure which restricts decline in the strength of the screw section. In order to achieve this, the tank according to the present invention includes a mouthpiece having a mouthpiece screw section which is formed with a screw thread and has a larger diameter on the outer side than on the inner side in an axial direction of the tank, and a valve having a valve screw section which corresponds only to a portion of the mouthpiece screw section. In this tank, when installing a product valve on the mouthpiece, it is possible to use a screw portion of the mouthpiece of which strength has not declined, by using, for example, a test valve and a product valve having different positions of the valve screw sections.
