Abstract
The utility model relates to an anti-explosive fuel tank for a locomotive. The fuel tank is characterized in that one end of a fuel tank body is connected with a fuel inlet return gas pipeline; an electric fuel pump, a gas vent valve (GVV) and an electric fuel pump with a fuel level sensor are connected to the fuel tank body; a fuel filter I and a fuel filter II are hung at the other end of the fuel tank body; an activated carbon canister is connected with the fuel filter I and the fuel filter II through an engine pipeline and connected with the GVV through an activated carbon canister pipeline; an air pipeline is connected to the activated carbon canister; one end of a fuel return pipe I and one end of a fuel discharging pipe I are connected with the electric fuel pump; the other ends of the fuel return pipe I and the fuel discharging pipe I are connected with the fuel filter I; one end of a fuel return pipe II and one end of fuel discharging pipe II are connected with the electric fuel pump with the fuel level sensor; the other ends of the fuel return pipe II and the fuel discharging pipe II are connected with the fuel filter II; two protective partition plates are respectively arranged on the left and right sides of the interior of the fuel tank body; the electric fuel pump, the GVV and the electric fuel pump with the fuel level sensor are wound by the partition plates; and the partition plates are positioned in the fuel tank body. The fuel tank cannot explode when the danger situations such as vehicle collision, overturn accidents, or military bullet and bomb attack occur.
Description
Technical field
The utility model relates to a kind of automobile-use explosion-proof fuel tank, and especially a kind of limousine is used explosion-proof fuel tank.
Background technique
Current society, the automobile industry develop rapidly, as the fuel tank of vehicle fuel reservoir vessel also gradually to lighting, safe, intelligent direction development.Gasoline or diesel oil are flammable and explosive substances; When fuel-steam concentration air mixing reached certain proportion, running into naked light or static will discharge lot of energy in the extremely short time; Produce high temperature; And emit a large amount of gases, and set off an explosion, be very dangerous for the personnel on the Motor Vehicle.
In the ordinary course of things, even there is naked light also can not set off an explosion in the motor vehicle oil tank, reason is that air concentration does not reach range of explosion; But when running into bullet and bombing raid in vehicle collision, overturn accident or the military affairs; Cause fuel tank to break easily, air gets in a large number, sets off an explosion.
The Chinese patent publication number: CN201863707 U provides a kind of explosion-proof fuel tank, mainly by fuel tank casing, isolated tube, obstruct is explosion-proof aluminum-foil netted forms.Wherein isolated tube and the explosion-proof aluminum-foil netted fuel tank box house that is installed in of obstruct can play the oil tank anti-explosion effect.Effect is: after air gets into fuel tank and fuel-steam mixes, can be cut apart by honeycomb cell, make combustable gas concentration not reach range of explosion.
Summary of the invention
The purpose of the utility model provides a kind of automobile-use explosion-proof fuel tank; It can guarantee not blast when motor vehicle oil tank runs into danger situation such as bullet and bombing raid on vehicle collision, overturn accident or military affairs take place, and protects motor-driven passengers inside the car and property safety.
The technological scheme of the utility model is achieved in that a kind of automobile-use explosion-proof fuel tank; It is characterized in that: fuel tank casing one end is connected with the oil-feed return line; The electric fuel punp that connects electric fuel punp, GVV valve, band fuel level sensor on the fuel tank casing, fuel tank casing the other end suspension I fuel filter, II fuel filter, charcoal canister is connected with I fuel filter, II fuel filter through engine pipelines; Charcoal canister is connected with the GVV valve through the charcoal canister pipeline; The atmosphere pipeline is connected on the charcoal canister, and I return tube, I oil outlet tube one end connect electric fuel punp, and the other end connects the I fuel filter; The electric fuel punp of II return tube, II oil outlet tube one end connecting band fuel level sensor, the other end connects the II fuel filter; The fuel tank box house each side has a protection dividing plate, and diaphragm rings is positioned at the fuel tank box house outside the electric fuel punp of electric fuel punp, GVV valve, band fuel level sensor.
The good effect of the utility model is effectively to suppress mixing of air and fuel-steam, and rapidly amount of localized heat is delivered to its place, the protection personal safety as well as the property safety, and function accessories are complete, safety coefficient is high; It is wide to transform high, the suitable vehicle scope of flexibility ratio, fuel strainer is housed, impurity in the adsorbable fuel oil; The protection motor, laterally Applicable scope is big, is not only applicable to Motor Vehicle; Also can be used for multiple fields such as navigation, petroleum storage, charcoal canister is housed, can absorb the fuel-steam that is evaporated; Prevent that it from getting into atmosphere and recyclable utilization again, safety environment protecting energy saving can guarantee that fuel tank fuel oil when upset takes place vehicle does not spill.
Description of drawings
Fig. 1 is the structural drawing of the utility model.
Fig. 2 is the generalized section of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further: like Fig. 1, shown in 2; A kind of automobile-use explosion-proof fuel tank; It is characterized in that: fuel tank casing 2 one ends are connected with oil-feed return line 1; The electric fuel punp 5 that connects electric fuel punp 3, GVV valve 4, band fuel level sensor on the fuel tank casing 2, fuel tank casing 2 the other ends suspension I fuel filter 7, II fuel filter 8, charcoal canister 10 is connected with I fuel filter 7, II fuel filter 8 through engine pipelines 9; Charcoal canister 10 is connected with GVV valve 4 through charcoal canister pipeline 6; Atmosphere pipeline 11 is connected on the charcoal canister 10, and I return tube 14, I oil outlet tube 15 1 ends connect electric fuel punp 3, and the other end connects I fuel filter 7; The electric fuel punp 5 of II return tube 13, II oil outlet tube 12 1 end connecting band fuel level sensors, the other end connects II fuel filter 8; Each side there is a dividing plate 16 fuel tank casing 2 inside, outside the electric fuel punp 5 of protection dividing plate 17 around electric fuel punp 3, GVV valve 4, band fuel level sensor, are positioned at fuel tank casing 2 inside.
The fuel oil transmittance process: fuel oil gets into fuel tank casing 2 through oil-feed return line 1 and contacts with the alloy foil net of all dividing plates 16 and wherein filling; Fuel-steam and air gas mixture abrim in the above space of fuel level this moment; Charcoal canister 10 links to each other the trim tank air pressure inside through the fuel-steam that charcoal canister pipeline 6 absorbs in this mixed gas with atmosphere with atmosphere pipeline 11; And flow to motor through the fuel-steam that has liquefied that engine pipelines 9 will wherein store; When motor-driven vehicle going, electric fuel punp 3 passes to I fuel filter 7 through I oil outlet tube 15 with fuel oil with the fuel oil sucking-off in the fuel tank casing 2, and I fuel filter 7 passes through I return tube 14 with the fuel delivery oil sump tank with impurity in the fuel oil and moisture filtering rear section fuel oil; The part fuel oil flows to motor through engine pipelines 9; The electric fuel punp of band fuel level sensor, 5 is similar with the working procedure of electric fuel punp 3, more than just an oil level detection function.
