The oil-filling device comprises an oil filling pipe and an exhaust pipe, wherein the lower pipe orifice of the oil filling pipe is connected on a fuel oil tank, a flow guide port body is inserted inside the upper pipe orifice of the oil filling pipe, the lower end port of the flow guide port body contracts inwardly to form a gun insertion port, a ventilation window is arranged on the side wall of the gun insertion port, the lower pipe orifice of the exhaust pipe is connected with the oil filling/exhaust joint of the fuel oil tank, the position of the oil filling/exhaust joint is higher than the lower pipe orifice of the oil filling pipe, the upper end of the exhaust pipe is communicated with the side wall of the upper pipe orifice of the oil filling pipe, a flow guide pipe is connected with the lower end of the flow guide port body, a lower baffle plate is arranged on the outer circumference of the lower pipe orifice of the flow guide pipe, and an upper baffle plate is arranged on the circumference below the ventilation window. The oil-filling device can not only smoothly fill oil, but also can effectively prevent fuel oil from upwelling when the oil filling gun is jumped after oil filling is finished, so as to avoid splash or spray of fuel oil.
Description
Technical field
The utility model relates to the fuel oil system fuel filler pipe assembly apparatus that a kind of anti-fuel oil splashes.
Background technology
Traditional fuel tank topping up device, comprise fuel filler pipe and freeing pipe, the lower nozzle of fuel filler pipe is connected on the fuel tank, be plugged with the flow-guiding mouth body in its upper orifice, the lower port of flow-guiding mouth body is inwardly shunk to form and is inserted muzzle, and the sidewall of inserting muzzle is provided with transom, and the lower nozzle of freeing pipe links to each other with the oiling exhaust joint of fuel tank, the position of oiling exhaust joint is higher than the lower nozzle of fuel filler pipe, and the upper end of freeing pipe is connected with the sidewall of fuel filler pipe upper orifice.During oiling, freeing pipe is constantly discharged the fuel-steam and the air on fuel tank top, and oiling is carried out smoothly.Oil level in fuel tank raises, and when the exhaust joint that refuels was gone up next flooded with fuel, freeing pipe got clogged, and the pressure in the fuel tank raises rapidly, and the oil level in the fuel filler pipe rises, and makes nozzle that the jumping rifle take place.Such topping up device refuels at a high speed the moment of finish jumping rifle at nozzle, and the fuel-steam pressure that fuel tank internal increases suddenly can cause the fuel oil of fuel tank to pour into the fuel filler pipe oral area rapidly, is easy to from transom and inserts muzzle splash or spray out.
The utility model content
For overcoming in the prior art, nozzle refuels at a high speed when finishing to jump rifle, fuel oil reaches the problem that muzzle splashes or sprays out of inserting from transom easily, the fuel oil system fuel filler pipe assembly apparatus that the utility model provides a kind of anti-fuel oil to splash, exhaust fuel vapors smoothly not only can prevent splashing or regurgitating of fuel oil again.
For solving above technical matters, the technical solution of the utility model is, the fuel oil system fuel filler pipe assembly apparatus that provides a kind of anti-fuel oil to splash, comprise fuel filler pipe and freeing pipe, the lower nozzle of fuel filler pipe is connected on the fuel tank, be plugged with the flow-guiding mouth body in its upper orifice, the lower port of flow-guiding mouth body is inwardly shunk to form and is inserted muzzle, the sidewall of inserting muzzle is provided with transom, the lower nozzle of freeing pipe links to each other with the oiling exhaust joint of fuel tank, the position of oiling exhaust joint is higher than the lower nozzle of fuel filler pipe, the upper end of freeing pipe is connected with the sidewall of fuel filler pipe upper orifice, the lower end of described flow-guiding mouth body is connected with mozzle, and the excircle of mozzle lower nozzle is provided with lower stop piece.
The beneficial effects of the utility model are to set up mozzle and lower stop piece in the lower end of flow-guiding mouth body, when refueling the moment that finishes, the fuel oil that raises and gush out owing to the pressure in the fuel tank, at first can run into lower stop piece, make fuel oil on to gush speed retarded, can not cause to splash or spray.
As improvement of the present utility model, the circumference of transom below is provided with upper stop piece.The fuel oil that stops through lower stop piece, on the speed of gushing descend, upper stop piece can further stop on the fuel oil and gush, and prevents that more reliably fuel oil from gushing out from transom.
Description of drawings
Fig. 1 is the utility model fuel tank topping up device single-piece structural representation.
Fig. 2 is the block diagram of flow-guiding mouth body and mozzle.
Among the figure: 1 fuel filler pipe, 11 mounting flanges, 2 freeing pipes, 3 flow-guiding mouth bodies, 31 transoms, 32 locking closure sealing threads, 4 mozzles, 41 lower stop pieces, 42 upper stop pieces, 43 are inserted muzzle.
The specific embodiment
As shown in Figures 1 and 2, the fuel oil system fuel filler pipe assembly apparatus that the anti-fuel oil of the utility model splashes, comprise fuel filler pipe 1 and freeing pipe 2, the lower nozzle of fuel filler pipe 1 is connected on the fuel tank, its upper orifice is provided with mounting flange 11 outward, fuel filler pipe 1 can be fixed on the automobile by mounting flange 11, is plugged with flow-guiding mouth body 3 in the upper orifice of fuel filler pipe 1, the top of flow-guiding mouth body 3 is provided with locking closure sealing thread 32, in order to be screwed into locking closure flow-guiding mouth is sealed.Flow-guiding mouth body 3 sidewall be provided with transom 31, transom 31 is positioned at fuel filler pipe 1, the lower end of flow-guiding mouth body 3 is connected with mozzle 4, mozzle 4 lower nozzle are inwardly shunk to form and are inserted muzzle 43, the excircle of inserting muzzle 43 is provided with lower stop piece 41, and the circumference of transom 31 belows is provided with upper stop piece 42.The lower nozzle of freeing pipe 2 links to each other with the oiling exhaust joint of fuel tank, and the position of oiling exhaust joint is higher than the lower nozzle of fuel filler pipe, and the upper end of freeing pipe 2 is connected with the sidewall of fuel filler pipe 1 upper orifice.
During oiling, fuel oil injects fuel tank by fuel filler pipe 1, and the fuel-steam in the fuel tank enters freeing pipe 2 from the oiling exhaust joint, is transported to the upper orifice place of fuel filler pipe then, discharges from transom 31.Oil level in fuel tank raises, and when the exhaust joint that refuels was gone up next flooded with fuel, freeing pipe 2 got clogged, and the pressure in the fuel tank raises rapidly, and the oil level in the fuel filler pipe rises, and makes nozzle that the jumping rifle take place.Refuel at a high speed the moment that finishes to jump rifle at nozzle, the fuel-steam pressure that fuel tank internal increases suddenly, the fuel oil that can cause fuel tank gushes on rapidly, on the fuel oil that gushes at first can run into lower stop piece 41, lower stop piece 41 stops the fuel oil that gushes on the major parts to continue to gush out, and not have to hinder fuel oil firmly on a small quantity, on the speed of gushing also can descend, can run into upper stop piece 42 when gushing in the continuation, upper stop piece 42 can further stop the fuel oil that gushes directly to gush out to cause by transom 31 to splash or spray.
