Description

technical field [0001] The invention relates to a storage tank gas phase communication device. Background technique [0002] The gas phase communication device of the storage tank is to connect the gas phase space of multiple storage tanks of the same oil product with pipelines to increase the volume of the gas phase space. It is accommodated in another storage tank to realize no or less discharge to the atmosphere, thereby reducing breathing loss. [0003] CN200510007223.1 relates to a barrier explosion-proof oil gas recovery device for an oil storage tank, which is a device for separating mixed oil gas exhaled from an atmospheric pressure oil storage tank and recovering condensed oil droplets into the oil storage tank. A ventilation pipe is arranged on the normal pressure oil storage tank, and the ventilation pipe is connected with a breather valve, and a barrier explosion-proof oil gas recovery device is arranged between the breather pipe and the breather valve. The cas...
