FIELD: filling station equipment.
SUBSTANCE: invention relates to fuel and energy complex, in particular to devices for filling stations, providing prevention of fuel spill, elimination of fires at filling stations, and device for its implementation. To prevent fuel spillage and fire extinguishing at automobile filling stations, the fuel hose and the dispensing gun are connected through connecting fittings using magnetic quick-release coupling, connecting fittings are equipped with disconnection sensors and light warning sensors installed on the fuel dispenser and the control room. Fitting connected by the fuel hose is equipped with an additional channel with the supplied extinguishing reagent through the spray nozzles built in the fitting with the possibility of automatic start-up when the temperature is detected by the temperature sensor, and cutoff valve of fuel supplied through fuel hose at rupture of dispensing gun. Proposed device comprises connecting fittings with temperature and rupture sensors connected by magnetic quick-release coupling, cable connecting rupture sensors with fuel dispensers, spray nozzles, extinguishing agent feed channel and fuel cutoff valve. Connecting fitting is connected to the fuel hose, which is made with a double wall with the possibility of supplying fuel along the inner part; a rupture sensor is installed on the outer wall of the connecting fitting; between the walls at the junction of the fuel hose and the dispensing gun there are spray nozzles connected to the extinguishing agent supply channel and the temperature sensor, connection fitting fixed to the dispensing gun is made with a disconnecting sensor on the housing, and the fittings are connected to each other by means of a magnetic quick-release connection.
EFFECT: simplified and compact design, autonomous and reliable operation, increased safety of fuel dispenser operation.
