DEVICE FOR OPERATIVE DEGASATION OF RAILWAY TRANSPORT EMERGENCY BREAKING SECTIONS UNDER CONDITION OF LIQUID HAZARDOUS CHEMICAL SUBSTANCES SPILLAGE Russian patent published in 2014 - IPC A62D3/00 E01H8/00 

FIELD: transport.

SUBSTANCE: invention relates to equipment for population protection against spillage of liquid hazardous chemical substances transferred by railway (r/w) transport and can be used for degasation of spillage sections on railway train braking path if container (tank) has lost pressurisation. Device includes container 1 with neutralising lotion installed on railway car chassis and connected by pipelines with car auxiliary reservoir with compressed air used in railway train braking system and with pipeline 12 for neutralising lotion discharge. Herewith, the device is located in front of the first along train motion of special tank cars containing hazardous chemical substances. Inside the container 1 with neutralising lotion, siphon 2 is fixed to the nozzle 4 of manifold 5 of which air pipeline 6 is connected, on which pipeline electropneumatic valve 7 automatically actuated during train emergency braking under condition of spillage of liquid hazardous chemical substances is installed, which valve in its turn is connected to compressed air auxiliary reservoir via reducing valve 10. The pipeline 12 for neutralising lotion discharge is provided with two slit valves 15 with expansion angle of at least 120° which valves are located under lower part of r/w car where outlets of valves 15 are located symmetrically at the distance of 80 cm from car centreline and facing opposite direction relative to train motion.

EFFECT: higher efficiency and operativeness of population protection against spillage of liquid hazardous chemical substances on emergency braking sections which spillage is caused by depressurisation or partial destruction without running off the rails owing to acts of terrorism of special tank cars with liquid hazardous chemical substances transferred by railway transport.
