Description
Technical field
It the utility model is related to field of automobile, and in particular to a kind of fuel tanks of automobile pipe-line system.
Background technology
Haulage vehicle particularly heavy-duty commercial vehicle, to extend transport mileage, generally use dual fuel tank is engine oil,
Limited by construction space, main fuel tank, the secondary fuel tank of existing dual fuel tank balance pipeline are respectively arranged in vehicle frame both sides（Referring to
Fig. 1）, suction tube for supplying it to engine from main fuel tank, by recurrent canal sent back to by the residual fuel returned from engine
Main fuel tank, balance pipe is used to connect two major and minor fuel tanks, when main fuel tank liquid level reduces, by siphonic effect from pair
Fuel tank supplements fuel to main fuel tank.To meet that design and vehicle driving requirements, balance pipe need to arrange along vehicle frame, its peak
Not less than fuel tank highest liquid level.Because the fuel returned from engine has higher temperature, make gas in the case of main fuel tank
Body pressure is more than secondary fuel tank, is unfavorable for fuel and is fed from secondary fuel tank to main fuel tank, causes secondary fuel tank completely clear
Sky, reduce the utilization rate of fuel.Under special circumstances, if having retained air or residue in balance pipe, easily formed and blocked,
Secondary fuel tank is caused to supplement fuel without normal direction main fuel tank.
In a word, existing dual fuel tank balance pipeline structure exists and can not empty fuel tank completely, can not discharge air
Shortcoming, utilization rate is low and increases later maintenance cost.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of fuel tanks of automobile pipe-line system.
The technical solution of the utility model：
A kind of fuel tanks of automobile pipe-line system, including vehicle frame, main fuel tank, secondary fuel tank, balance pipe, suction tube and return
Pipe, the main fuel tank and secondary fuel tank are located at the both sides of vehicle frame respectively, by flat between the main fuel tank and secondary fuel tank
Weighing apparatus pipe is connected, and in one end insertion main fuel tank of the suction tube, one end of the recurrent canal is accessed in secondary fuel tank.
A kind of fuel tanks of automobile pipe-line system, the balance pipe are provided with check device, and the check device is positioned at balance
The middle part of pipe, i.e., between described fuel tank and secondary fuel tank.
A kind of fuel tanks of automobile pipe-line system, the check device are made up of snap joint and check valve, the check valve
Between the snap joint and main fuel tank.
A kind of fuel tanks of automobile pipe-line system, the check device include snap joint, check valve, air collector and exhaust
Valve, the air bleeding valve are located at the top of air collector, and the check valve is described quick between the air collector and main fuel tank
Joint is between air collector and secondary fuel tank.
The beneficial effects of the utility model：
The utility model increases snap joint and check valve by changing the position of recurrent canal in balance pipe, relatively
For existing double fuel balance pipeline structure, it has advantages below：Recurrent canal is arranged in secondary fuel tank, makes secondary fuel
The loading pressure of case improves fuel availability not less than the gas pressure in main fuel tank；Blocked when existing in pipeline
When, the snap joint that need to only dismantle on balance pipe is emptied, and easy to maintenance, cost is cheap.
Brief description of the drawings
Fig. 1 is existing dual fuel tank balance pipeline structure schematic diagram.
Fig. 2 is a kind of schematic diagram of embodiment 1 of fuel tanks of automobile pipe-line system.
Fig. 3 is a kind of schematic diagram of embodiment 2 of fuel tanks of automobile pipe-line system.
In accompanying drawing：1. main fuel tank；2. secondary fuel tank；3. balance pipe；4. suction tube；5. recurrent canal；6. vehicle frame；7. non-return
