Fire extinguishing agent container - has rubber vessel fitted inside metal vessel both optionally usable for agent or gas

摘要

The vessel (1) for an extinguishing agent is made of metal and the vessel (2) is fitted an inside vessel (1) filled with pressurised gas. Inside the metal vessel (1) a screen (3) is fitted at some distance from the inner surface of the vessel (1). The assembly is fitted with an external pressure (4) connected with the internal rubber vessel (2) via a pressure reducing unit. When the shut off valve of the pressure reducing unit is opened pressure gas flows from pressure cylinder (4) into the rubber vessel (2) which expands and forces the extinguishing agent from the metal vessel (1) out of the vessel until the walls of the rubber vessel (2) come to rest against screen body.
