Third end is suitable for connecting with tank truck gas phase interface.When emptying, the triple valve closes the emptying general pipeline, makes the recycling
General pipeline cannot be introduced into the emptying general pipeline with oil gas when tank truck gas phase orifice namely petroleum vapor recovery, realize oil gas
Recovery of Seal Oil；After the completion of emptying, the triple valve will be closed with one end of tank truck gas phase orifice, make the emptying general pipeline
It is connected to the recycling general pipeline, the buried tank can maintain stable gas pressure by the emptying general pipeline.
Further, each recycling branch pipe is connected in the position higher than the buried tank highest liquid level 3.5m, this
The form of high position connection, can be effectively prevented emptying spill-over, alters oily accident.
Further, the upper end of the emptying general pipeline is equipped with the back-fire relief Ventilated cap with breather valve, and the two can prevent oil gas
Inorganization outlet.
Further, the gas recovery system for oil of the gas station one time further includes emptying branch pipe and setting in emptying branch
The lower end of the back-fire relief Ventilated cap of pipe upper end, the emptying branch pipe is connected to the recycling general pipeline, and the lower end of the emptying branch pipe is high
In the lower end of the emptying general pipeline.
Further, the gas recovery system for oil of the gas station one time further includes the cold liquefaction unit of film, the recycling general pipeline with
The cold liquefaction unit connection of film.
Further, the bottom of the recycling general pipeline is equipped with discharging valve, for discharging the aqueous vapor in the recycling general pipeline, by
When recycling general pipeline running, internal since self-solidifying can generate part aqueous vapor, this part water passes through the discharging valve and valve
Well discharge.
Further, the bottom of the emptying general pipeline is equipped with discharging valve, for discharging the aqueous vapor in the emptying general pipeline.
It compared with prior art, can be effective the utility model has the beneficial effects that: by making to recycle the connection of a branch pipe high position
It prevents spill-over when emptying, alter oil；By being arranged three between the recycling general pipeline, the emptying general pipeline and tank truck gas phase interface
Port valve, it is ensured that when emptying and normal work, oil gas does not run leakage.
