Description
Art
The present invention relates to the oiling gun system of gas station, oiling technology is especially sealed.
Background technology
Vehicle in fuel up, due to the volatilizable property of fuel oil, when fuel oil enters inside fuel tank rear fuel tank at a high speed
Fuel oil can accelerate with air contact and splash bubble, form the combustion mixture of fuel oil and air and the ejection fuel tank of high speed, this
Gaseous mixture can stay for some time without dissipating immediately around vehicle and fuel charger, once run into naked light, Mars or electrostatic
Can be ignited, although gas station there are clear stipulaties, and No Open Flames, but the electric spark and equipment and human body product that vehicle electric element occurs
Raw electrostatic cannot but completely cut off, and the existing sealing oiling technology of in the market is excessively complicated due to equipment, and inconvenience etc. is operated during oiling
Factor is difficult to be commercially available popularization, and the fire incident that many gas stations occur is ignited fuel gas by electrostatic or naked light
And cause, greatly threaten the security of the lives and property of gas station and staff.
The content of the invention
To solve the problems, such as that the fuel gas produced during existing gas station's oiling can not be eliminated in time, the invention provides one
The getter device of nozzle is planted, by air-breathing set, exhaust tube, negative pressure ventilation machine, blast pipe and sensing starting switch composition, the device
Once mounting can be molded when nozzle is produced, later stage installation can be also carried out to existing nozzle, air-breathing set is arranged on nozzle
Fuel filler neck on, by exhaust tube connect negative pressure ventilation machine, sensing starting switch be arranged on fuel charger on place nozzle at, be used to
The Switching Power Supply of negative pressure ventilation machine is controlled, negative pressure ventilation machine is started working when nozzle is removed from fuel charger, gas is from suction
Air-casing suction enters negative pressure ventilation machine through exhaust tube, and the gas that will be extracted out by blast pipe discharges gas station, during oiling, due to refueling
Air-breathing set on mouth constantly sucks gas, and fuel tank internal can produce negative pressure, and gas enters fuel tank, now produces by reservoir port
Raw fuel gas is timely extracted out by air-breathing set, and gas station is discharged by blast pipe through negative pressure ventilation machine, during so as to preventing from refueling
There is the danger of fire after being ignited in the fuel gas of generation.
Brief description of the drawings
Make further details of explanation to the present invention below in conjunction with the accompanying drawings.
Fig. 1 is nozzle structure chart.
Fig. 2 is equipment overall structure figure.
Specific embodiment
According to Fig. 1 as can be seen that air-breathing set (1) covers for circle, near the one of fuel filler neck (3) on nozzle (2)
End, gas can be inhaled into by opening port, and rear end connects exhaust tube (4), and exhaust tube is resistance to compression rubber tube, is used when installing in the later stage
Adhesive tape is wrapped on oil pipe (5), and factory's one-shot forming can be hidden in inside oil pipe when installing.
According to Fig. 2 as can be seen that nozzle (2) connects fuel charger (6), exhaust tube (4) connection negative pressure ventilation by oil pipe (5)
Machine (7), negative pressure ventilation machine drives air extractor to constitute by motor, and negative-pressure sucking is produced to air during work, will by exhaust tube (4)
The air suction at air-breathing set (1) place, gas station is discharged by blast pipe (8), and sensing starting switch (9) is placed on fuel charger
At nozzle, mode is switched on for induction type, be used to control the Switching Power Supply of negative pressure ventilation machine, when nozzle from fuel charger
On when removing switch can open and by power on, negative pressure ventilation machine is started working, switch pass after nozzle puts back to original position
Close, negative pressure ventilation machine is stopped, blast pipe front end connection negative pressure ventilation machine, connection total air escape pipe is concentrated in rear end, by being always vented
The fuel gas extracted out from fuel tank internal is discharged into pipe the place from gas station farther out, is beneficial to dissipation and the gas station of gas
Safety.Compact gasoline station is small because of workload, can be by the way of a fuel charger configures a negative pressure ventilation machine, large-scale oiling
Workload of standing is big, can be by the way of a large-scale negative pressure ventilation machine connects many fuel chargers, to save many negative pressure ventilations
Exhaust tube on the electric energy of machine, large-scale negative pressure ventilation machine and fuel charger is directly controlled by electromagnetic gas valve control by sensing starting switch
The opening and closing of electromagnetic gas valve processed.
When equipment works, nozzle is removed from fuel charger, sensing starting switch work and by power on, negative pressure ventilation
Machine or electromagnetic gas valve are worked, and nozzle is inserted the fuel tank of automobile, and now the air-breathing set on fuel filler neck constantly sucks gas,
Fuel tank internal can produce negative pressure, and gas enters fuel tank by reservoir port, and the fuel gas that now fuel tank internal is produced is by air-breathing set
Timely extract out, gas station is discharged by blast pipe through negative pressure ventilation machine, therefore the mixing of oil gas will not be produced when refueling in fuel tank
, there is the danger of fire after being ignited so as to the fuel gas that when preventing from refueling and gas station produces in fuel gas.
