FIELD: machine building.

SUBSTANCE: relief valve for reservoirs consists of hollow case with valves of pressure and vacuum and connecting flanges and of contact weight-exchange device installed inside case. The weight exchange device is equipped with a disk and is sprinkled by means of a circular collector mounted on top of it. The collector is coupled with a pipeline for cooled oil product supply. The disk is installed in a middle part of the case. In the lower part of the case there is installed a ring coaxially to the branch of steam-(gas)-air mixture inlet. An upper edge of the ring is positioned over the lower edge of the weight exchange device at a value eliminating slippage of steam (gas) over a layer of liquid accumulated in the lower part of the case.

EFFECT: increased efficiency of relief valve operation and reduced losses of oil products.
