Definitions

  • the present invention relates to a high-pressure tank. More specifically, the present invention relates to an improvement in the structure around a valve in a high-pressure tank filled with hydrogen gas or the like.
  • a structure in which a valve assembly (a part incorporating a high-pressure valve) is attached to a base provided in an opening of a high-pressure tank body is used. Further, when the valve assembly is attached to the base, a simple screw structure is often used in which the threaded portion of the valve assembly is screwed into the female thread portion of the base.
  • a high-pressure tank for example, a high-pressure container having a base and a pressure valve
  • the liner-facing surface of the flange portion of the base (the surface of the flange portion facing the liner constituting the tank housing) Have a vent hole whose one end is open (see, for example, Patent Document 1).
  • Japanese Patent Laid-Open No. 11-082887 Japanese Patent Laid-Open No. 11-082887
  • the gas accumulated in the gap between the base and the plug cannot be discharged to the outside.
  • a high-pressure tank having a structure in which the gas accumulated in the gap in the tank can be discharged to the outside of the tank has been proposed, but in some cases, a high cost may be required.
  • an object of the present invention is to provide a high-pressure tank having a structure capable of realizing low cost while suppressing gas accumulation in a space between a valve and a base.
  • the present inventor has made various studies to solve such problems.
  • rubber seals are often used at the end of the valve on the tank body side.
  • the gas vent hole (gas vent hole) is processed.
  • a waterproof and breathable material having waterproofness and air permeability (for example, Gore-Tex (registered trademark)) is used.

Abstract

La présente invention concerne une cuve haute pression (1) comportant une structure dans laquelle une accumulation de gaz dans un espace (70) compris entre une soupape (50) et un raccord (11) est supprimée et qui permet que la cuve soit produite à faible coût. La cuve haute pression (1) comportant le raccord (11) et la soupape (50) montée sur le raccord (11) comprend en outre un trou de communication (51) et un évent de gaz (52). Le trou de communication (51) interconnecte des espaces (70, 80) formés entre le raccord (11) et la soupape (50) ou dans la soupape (50) et qui rendent possible l’accumulation, dans les espaces, d’un gaz transmis depuis le côté de la cuve. L’évent de gaz (52) raccorde l’un ou l’autre des espaces (70, 80) à l’extérieur de la cuve. Le trou de communication (51) est de préférence situé plus près du centre de la cuve qu’une section filetée (53) de la soupape (50). En outre, de préférence, l’évent de gaz (52) mène depuis l’espace (70), formé entre le raccord (11) et la soupape (50), dans le sens dans lequel ledit évent croise la surface de contact entre le raccord (11) et la soupape (50).
