Gas storage container, for helium under pressure for quenching systems, has an inner flexible container of a gas-permeable material within an outer container filled with an inert gas

摘要

The gas storage container (2), with a flexible shape, is of a gas-permeable material e.g. coated rubber or textile-reinforced polyester shrouded by an outer container (4) of a gas-permeable material and/or of a gas-impermeable material. The outer container storage zone (3) is filled with a gas or gas mixture which is free of oxygen, or an inert gas. The inner container has a monitor (5,6) to register a gas concentration. The gas storage container (2), with a flexible shape, is of a gas-permeable material e.g. coated rubber or textile-reinforced polyester shrouded by an outer container (4) of a gas-permeable material and/or of a gas-impermeable material. The gas storage container has a system (7,8) to feed gas or a gas mixture into and out of the storage zones (1,3) within the container. The outer container storage zone (3) is filled with a gas or gas mixture which is free of oxygen, or an inert gas. The inner container has a monitor (5,6) to register a gas concentration, and preferably the level of oxygen present. The pressure and/or volume changes in one of the containers is controlled by adjusting the pressure and/or volume in the other container.
