FIELD: package and storage.
SUBSTANCE: invention relates to railway tanks. In a rail explosion-proof tank containing a boiler with a hatch, safety inlet valve and drainage device, the cylindrical shell of the boiler is provided with a shadow protection. Explosion-proof device with a warning system for the initial phase of an emergency situation, containing a valve body (11) with a lined cargo gate (12) is mounted in the tank hatch. Round diaphragm (20) with apertures is installed in the valve body. In the upper part, covered with an armored layer, of a lined cargo gate, the shaft, located in the central aperture of the diaphragm, is axially symmetric to the valve body, and between the lower part of the circular diaphragm and the upper part of the lined cargo gate, a bushing (24) is placed on the support rod from a rapidly breaking material, the strength of which is calculated for a certain overpressure in the valve. On the fast-disconnecting sleeve (24), secure the safety indicator, the signal from which enters the alarm system unit for emergency mode.
EFFECT: invention increases the explosion safety of a railway tank.
