摘要： A system for discharging inert gas for extinguishing or suppressing a fire is disclosed. A fluid discharge control arrangement is positioned in a fluid flow path between a pressurised gas supply 10A,10B,10C and the target fire suppression zone 20. The fluid discharge control arrangement reduces the pressure in the fluid flow path downstream thereof. This may allow the downstream pipework to be selected to withstand a lower pressure than in a conventional system in which the fluid discharge control device was not provided, thereby reducing costs. The fluid discharge control device may comprise a first valve 30 and first restrictor 26 in the first flow path 22 and a second valve 32 and a second restrictor 28 provided in the second flow path 24. Fluid from the containers 10A,10B,10C flows initially through flow path 24 and restrictor 26. Subsequently flow path 22 may be closed by optional valve 30, and flow path 24 is opened by valve 32. Fluid flow then passes through restrictor 28. This reduces the peak pressure in the downstream pipework 34. In another embodiment the discharge of inert gas from the containers 10A,10B and 10C is staggered to reduce the peak pressure in pipeline 34. A further embodiment provides a restrictor in the inlet 14A,14B,14C from each of the containers 10A,10B,10C to the manifold 16, thereby also reducing the peak pressure in the pipeline 34.
