| 摘要 |
The fire extinguisher (100) has a pressure reducing device (6) including parallel branches (21, 31, 41) with respective pressure reducing units (22, 32, 42). The branches are connected to a high pressure collecting line (3) and a low-pressure extinguishing line (4) via respective controllable valves (23, 33, 43). Each pressure reducing unit reduces a high input pressure to a low output pressure according to a preset pressure reducing characteristic. The extinguishing line is connected with an extinguishing nozzle (5) via the pressure reducing device. An independent claim is also included for an inertization method for reducing the risk of fire and for extinguishing fire in a protected space. |
