| 摘要 |
The present invention relates to a fire extinguishing system comprising a pressurized detection conduit (115), an extinguishing line (108) separate from the detection conduit (115), and a control module (105) adapted for sensing a pressure drop in the detection conduit (115) and for opening supply of extinguishing medium from a storage (103) to the extinguishing line (108). The detection conduit (115) is gas-permeable and filled with a detection liquid. The fire extinguishing system further comprises a liquid-gas interface (117) fluidly connecting the detection conduit (115) to a pressurized gas source (103, 106), wherein the liquid-gas interface (117) comprises an interface container (123) defining a gas space (131) which communicates with the pressurized gas source (106) and a liquid space (133) which communicates with the detection conduit (115). |
