Abstract
The utility model relates to a diversion device for discharging fuel oil and gas of a fuel tank of a motorcycle, which comprises the fuel tank and an fuel tank cover, wherein an fuel tank opening is arranged at the top part of the fuel tank, a depressions is arranged at the periphery of the fuel tank opening, or the depression is covered by an fuel tank decoration cover. The diversion device is characterized in that an fuel tank opening sleeve is arranged on the fuel tank opening, the bottom part of the fuel tank opening sleeve is positioned in the fuel tank, the middle part and the upper part of the fuel tank opening sleeve are positioned outside the fuel tank opening, a diversion tube is fixed at one side of the fuel tank opening sleeve, the diversion tube passes through a fuel tank shift for spanning on a motorcycle frame, the bottom of the diversion tube is connected with a diversion hose, and a vent hole for balancing gas pressure are arranged on the fuel tank opening sleeve. In the utility model, by the diversion device for discharging fuel and gas, overflowed fuel is led out of the depression or the fuel tank decoration cover of the fuel tank opening, the surface layer of the fuel tank or/and the surface layer of the fuel tank decoration cover can not be corroded, the cleaning of the surface of the fuel tank is convenient, simultaneously, the gas pressure in the fuel tank can be timely adjusted, the gas pressure in the fuel tank is balanced, and the fuel overflow phenomenon is reduced.
Description
Technical field
The utility model belongs to motorcycle field, is specifically related to a kind of motorcycle tank draining, disappointing guiding device.
Background technology
Motorcycle tank is the vitals of motor bike, and usually the both sides of motorcycle tank are used for the splendid attire fuel oil, and the centre is the fuel tank crotch that is used on the frame of motorcycle, and the structure of described fuel tank crotch is the inner hollow sealing member that is.The top of motorcycle tank is provided with pouring orifice, and fuel lid is arranged on the reservoir port.Be provided with depression around the reservoir port of the motorcycle tank that has, the fuel oil aggregation that will overflow is in depression, and the motorcycle oil box top that has also is provided with the fuel tank cover of upholstery.Motor bike in the process of moving, be contained in the motion process of the fuel level motor bike in the fuel tank and can overflow fuel tank, during perhaps because of engine operation, the fuel-steam that produces because of factors such as temperature traverses of fuel tank, make gas expansion in the fuel tank, air pressure raises, and after fuel-steam overflows reservoir port, condenses into the recess that liquid fuel accumulates in reservoir port, corrode the superficial layer of fuel tank and/or the superficial layer of cover of upholstery, influence the cleaning of fuel tank.
Summary of the invention
The purpose of this utility model provides a kind of motorcycle tank draining, disappointing guiding device, it is by draining, disappointing guiding device, the fuel oil that will overflow is drawn the depression or the fuel tank cover of upholstery of reservoir port, the superficial layer of fuel tank and/or the superficial layer of cover of upholstery can not be etched, and are beneficial to the cleaning of tank surface; Can also in time adjust the air pressure in the fuel tank simultaneously, the air pressure in the trim tank reduces overflowing of fuel oil.
The technical solution of the utility model is: a kind of motorcycle tank draining, disappointing guiding device, comprise fuel tank, fuel lid, the top of fuel tank is provided with reservoir port, be provided with depression around the reservoir port or cover depression with the fuel tank cover of upholstery, be positioned at fuel tank middle part and top bottom reservoir port is provided with and be positioned at reservoir port outer container muzzle pipe, fuel lid covers the top at the reservoir port sleeve pipe, one side of described reservoir port sleeve pipe is fixed with mozzle, described mozzle passes the fuel tank crotch that is used on the frame of motorcycle, and the bottom of oil guide pipe is connected with stream guiding tube;
And the reservoir port sleeve pipe is provided with the air extractor vent that is used for equilibrium air pressure.
Described air extractor vent is higher than the fuel tank outer surface of cupular part.
Described reservoir port sleeve pipe and mozzle welding are fixing.
Described reservoir port sleeve pipe bottom surface and fuel tank are limit oily line in-line.
Owing to adopt technique scheme, be provided with the reservoir port sleeve pipe at reservoir port, one face down bonding of sleeve pipe is connected to mozzle, oil guide pipe is connected with stream guiding tube, motor bike can be overflowed in the process of moving the fuel oil of fuel tank, and the fuel-steam that produces during with engine operation, draw outside the depression or fuel tank cover of upholstery of reservoir port from oil guide pipe and Oil Guide flexible pipe, the superficial layer of fuel tank and/or the superficial layer of cover of upholstery can not be etched, and are beneficial to the cleaning of tank surface; Air extractor vent on the reservoir port sleeve pipe is communicated with atmosphere, fuel oil in fuel tank produces fuel-steam because of temperature build-up, when the fuel tank internal gas pressure is raise, the air extractor vent that is communicated with atmosphere can in time be discharged fuel-steam, air pressure in the trim tank, avoid fuel-steam to overflow reservoir port after, condense into the recess that liquid fuel accumulates in reservoir port, corrode the superficial layer of fuel tank and/or the superficial layer of cover of upholstery, influence the cleaning of fuel tank.
