A device for detonation spraying contains, mounted in a room,a hose (1) connected to a gas mixer (5) which is connected to a fuel gas line (6), to an inert gas line (7) and to an oxygen line (8), each of them being connected to a corresponding source (10,11,12) of gas supply. Each of the lines (6,7,8) comprises, mounted consecutively along the gas flow, a gas pressure reducer (15,21,28), a control valve (16, 22,29), a gas flow discharge meter (17, 23,30) and a main normally closed valve (19,25,32). Each of the lines (6) of the fuel gas and (8) of oxygen comprises, respectively, an additional normally closed valve (13,27) located outside the room and connected to the corresponding source (10 and 12) of gas supply. The main (19,25,32) and additional (13,27) normally closed valves are connected to a gas supply control unit (39) connected to a control system (40). <IMAGE> |
