Background technology
Because oil product is very easy to volatilization, during gas station's oil storage tank stores and receives and dispatches oil product, oil storage tank breathing
Caused exhaust of oil includes two kinds of forms of Big and Small Breath：Big breathing and small breathing.Small breathing refers to the heat caused by temperature changes
Swollen shrinkage, environment temperature cause pressure inside the tank change suction air and exhaust of oil；When big breathing refers to oil storage tank transmitting-receiving operation, tank
Interior gas pressure change causes oil storage tank discharge oil gas and suction air.
Existing gasoline station oil gas discharge Treatment process is roughly divided into a stage petroleum vapor recovery, two-stage petroleum vapor recovery and three ranks
Section petroleum vapor recovery.One stage petroleum vapor recovery for oil truck to during oil storage tank emptying, the increase of oil storage pressure tank, caused oil
Gas is recycled to oil truck, and this process also results in the big breathing of oil storage tank and breather valve opens exhaust of oil；Two-stage petroleum vapor recovery
Refer to automobile fuel filler during, petroleum vapor recovery caused by automotive oil tank to oil storage tank, due to requirements of the national standard gas liquid ratio be more than
1：1, i.e. oil storage tank sends the volume of liquid oil and is less than petroleum vapor recovery volume, causes the increase of oil storage pressure tank to produce oil gas row
Put；Three stage petroleum vapor recoveries are also known as " reinforcement petroleum vapor recovery ", and size caused by oil storage tank pressure change is exhaled during solving transmitting-receiving

The problem of existing following tank of oil storage tank flattens weighing apparatus and breather valve exhaust of oil：
1st, during oil storage tank transmitting-receiving operation, gas pressure change causes oil storage tank discharge oil gas and suction air in tank.Due to
The gas liquid ratio of two-stage gas recovery system for oil is more than 1：1, the oil-gas ratio returned in tank adds the oil more, plus the oil of volatilization naturally
Gas, pressure inside the tank can gradually rise, and also cause breather valve to discharge oil gas；
2nd, due to environmental change, phenomenon of expanding with heat and contract with cold, when oil storage tank system temperature reduces, breather valve can suck air,
When oil storage tank system temperature raises, oil evaporation aggravation, pressure inside the tank increase will；Oil storage tank carries out transmitting-receiving operation process
In, when oil tank oil-feed, due to the increase of pot liquid volume, gas pressure increases in tank, when pressure increases to breather valve pressure pole
In limited time, breather valve automatically turns on to surrounding environment and discharges gas.
