BREATHING VALVE FOR RESERVOIRS Russian patent published in 2000 - IPC

FIELD: mechanical engineering. SUBSTANCE: breathing valve is intended for use on reservoirs with rigid stationary roof. Breathing valve has hollows body with pressure and vacuum valves and with connecting flanges. Contact device is positioned inside body and sprayed with aid of circular collector mounted above it. Circular collector is connected to pipeline for delivery of cooled petroleum product. Disc-deflector perforated over periphery is installed above circular collector. Disc-deflector supports auxiliary contact device-entrainment separator positioned above it. Breathing valve makes it possible to reduce losses of petroleum products and to decrease ejection of hydrocarbon vapors into atmosphere. EFFECT: enhanced efficiency. 2 dwg
