Description
Technical field
The utility model relates to motorcycle part, particularly a kind of fuel tank of motor bike.
Background technology
Motorcycle tank is generally made up of casing and the case lid be arranged on casing top, opens case lid, can refuel in fuel tank.
In prior art, in order to make the fuel oil in fuel tank flow out smoothly, case lid is generally all provided with air equalizer opening, to make the air pressure in fuel tank equal with barometric pressure.Although this structure can make fuel tank IFO intermediate fuel oil flow out smoothly, the oil vapour in fuel tank also can be run out of simultaneously from air equalizer opening, causes fuel oil to waste and aerial contamination.
In order to solve oil vapour leakage problem, normally adopt in prior art and a ventilation flue is set in fuel tank, the inlet end of ventilation flue is positioned at casing, outlet side is connected with the canister be arranged on outside fuel tank, by the active carbon in canister by the absorption of oil gas, avoid oil gas to leak, canister is communicated with air simultaneously, can discharge smoothly to realize fuel tank IFO intermediate fuel oil.
Although this technology solves the problem that oil vapour in fuel tank leaks outside, but due to when driving, because fuel oil rocks comparatively violent, easily occur that fuel oil enters and be arranged in the ventilation flue of fuel tank internal, cause ventilation flue to block, the problem such as canister damage, make its functional reliability poor; And when vehicle meet accident fall down time, fuel oil easily enters canister with ventilation flue and causes canister to damage.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of anti-fuel-steam and leaks outside type motorcycle tank, to solve existing motorcycle tank IFO intermediate fuel oil steam leakage and fuel oil enters the problems such as ventilation flue's blocking and canister damage.
The anti-fuel-steam of the utility model leaks outside type motorcycle tank, comprise casing and case lid, fuel-steam delivery pipe is provided with in described casing, also comprise the seal closure be welded in casing top outside, the inlet end of described fuel-steam delivery pipe upwards passes casing top and is positioned at seal closure, the outlet side of described fuel-steam delivery pipe is positioned at outside casing, the casing top being positioned at seal closure is also provided with induction opening, the cabinet wall of induction opening lower end is provided with oil resistance web-roll core.
Further, described seal closure is also provided with oil swellable rubber, described oil swellable rubber rubber is positioned at directly over fuel-steam delivery pipe.
Further, interval 1.0 ~ 1.5mm between described oil swellable rubber rubber and the upper end of fuel-steam delivery pipe.
The beneficial effects of the utility model:
The anti-fuel-steam of the utility model leaks outside type motorcycle tank, it by arranging seal closure outside casing, the inlet end of steam output pipe is arranged on outside casing, and oil resistance web-roll core is set in induction opening portion, make in the fuel oil seal closure more difficult to get access that rocks when driving, thus can avoid fuel oil enter steam output pipe cause block and canister damage problem, by steam output pipe the fuel-steam in fuel tank exported in the canister outside fuel tank simultaneously and store, solve fuel-steam and to leak the atmospheric contamination and fuel oil waste problem that cause.
Accompanying drawing explanation
Fig. 1 is that anti-fuel-steam leaks outside the sectional structure schematic diagram of type motorcycle tank.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the anti-fuel-steam of the present embodiment leaks outside type motorcycle tank, comprise casing 1 and case lid 2, fuel-steam delivery pipe 3 is provided with in described casing, also comprise the seal closure 4 be welded in casing top outside, the inlet end of described fuel-steam delivery pipe upwards passes casing top and is positioned at seal closure, the outlet side of described fuel-steam delivery pipe is positioned at outside casing, the casing top being positioned at seal closure is also provided with air inlet 5 hole, the cabinet wall of induction opening lower end is provided with oil resistance web-roll core 6.In concrete enforcement, the outlet side of fuel-steam delivery pipe is connected with the canister be arranged on outside casing, by the charcoal absorption fuel-steam in canister, while canister also identical with air, realize fuel tank internal air pressure and barometric pressure balances.
The anti-fuel-steam of the present embodiment leaks outside type motorcycle tank, it by arranging seal closure outside casing, the inlet end of steam output pipe is arranged on outside casing, and oil resistance web-roll core is set in induction opening portion, make in the fuel oil seal closure more difficult to get access that rocks when driving, thus can avoid fuel oil enter steam output pipe cause block and canister damage problem, by steam output pipe the fuel-steam in fuel tank exported in the canister outside fuel tank simultaneously and store, solve fuel-steam and to leak the atmospheric contamination and fuel oil waste problem that cause.
As the improvement to the present embodiment, described seal closure is also provided with oil swellable rubber 7, described oil swellable rubber rubber is positioned at directly over fuel-steam delivery pipe, when there is unexpected overturning in motor bike, oil resistance web-roll core 6 can not realize stoping fuel oil to enter in seal closure, and when fuel oil enters after in seal closure, oil swellable rubber 7 can expand by fast absorbing oil, by the import shutoff of fuel-steam delivery pipe, thus the problem that fuel oil leaks in a large number with fuel-steam delivery pipe can be avoided.
As the improvement to the present embodiment, interval 1.0mm between described oil swellable rubber rubber and the upper end of fuel-steam delivery pipe, certainly in different embodiments, the spacing distance between the upper end of oil swellable rubber rubber and fuel-steam delivery pipe also can be other values within the scope of 1.0 ~ 1.5mm; Spacing distance in the present embodiment is less, not only can the speed revealed from fuel-steam delivery pipe of slowing oil, also can shorten the time of oil swellable rubber rubber swelling shutoff fuel-steam delivery pipe inlet end, be conducive to reducing fuel oil and reveal flow.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
