Verfahren und Struktur zur Beschickung von brennbarem und oxydierendem Gas und so beschicktes Material

摘要

After a high-pressure container 1 is mounted to a charging jig 2, on-off valves 82 and 83 are closed, and on-off valves 81 and 84 are opened, so as to draw a vacuum in each of a charging path7, the charging jig 2 and the high-pressure container 1. After drawing the vacuum, the on-off valve 84 is closed, the on-off valve 83 is opened, for charging a hydrogen from a combustible gas source 43 into the high-pressure container 1 through a charging port 11. When a pressure within the container reaches a predetermined pressure, the on-off valve 81 and 83 are closed. In this manner, the hydrogen is charged into the high-pressure container 1 in a range except a flammable range. Then, the on-off valve 84 is opened to draw a vacuum only in the charging path 7. After drawing the vacuum, the on-off valve 84 is closed and the on-off valve 82 is opened to charge an oxygen from an oxdizer gas source 5 into the high-pressure container 1. In this manner, the oxygen is charged into the high-pressure container 1 in a range except the flammable range. If a pressure within the high-pressure container 1 reaches a predetermined pressure, a sealing member operating mechanism 3 is operated so that the charging port 11 of the high-pressure container 1 is sealed by a sealing member 12.
