Abstract
The utility model discloses a volatilization prevention fuel tank. The volatilization prevention fuel tank comprises a tank body with a fuel inlet and an upper cover screwed on the fuel inlet and provided with inner threads. The tank wall of the tank body is composed of an inner layer and an outer layer, and thermal insulation material is filled in an interlayer formed by the inner layer and the outer layer in an enclosed mode; and a floating cover plate which is horizontally arranged in the tank body and provided with an fuel inlet in the middle slides along a guide device in the tank body in a vertical mode. A flexible seal liner is placed in the inner side of the top wall of the upper cover, an air inlet pipe is arranged from the outside of the top wall of the upper cover into an inner seal of the fuel inlet in an extension mode, and the air inlet pipe arranged outside the top wall of the upper cover is provided with a one-way air inlet valve. The volatilization prevention fuel tank has the advantages of being simple in structure, compact in size, convenient to use and obvious in fuel volatilization prevention effect. Through the insulation material filled in the interlayer formed by the inner layer and the outer layer, fuel in the tank body can be kept in a stable low-temperature state, and volatilization speed of the fuel is slowed down; and through the floating cover plate always placed on a fuel face, the contact area of the fuel and air is reduced, and volatilization of the fuel can be reduced effectively.
Description
Technical field
The utility model relates to the motor vehicle fuel case, especially relates to a kind of volatilization prevention fuel tank.
Background technology
The oil inlet of general-duty motor vehicle gasoline machine fuel tank must seal with fuel lid, to guarantee that fuel oil can not flow out from oil inlet, simultaneously to guarantee that also outside air can enter in the fuel oil casing from oil inlet during motor-driven vehicle going, to eliminate because the consumption of fuel oil and the negative pressure that in fuel tank, produces.
The gasoline engine fuel case mostly is single layer structure at present, in the motor-driven vehicle going process, if temperature is too high, can quicken the volatilization of fuel oil, causes the waste of fuel oil; The mode that generally adopts screw thread to spin between oil inlet and the fuel lid seals simultaneously, the fuel lid inboard is threaded, after it is screwed on the oil inlet, though outside air enters in the fuel tank the thread pitch between fuel lid and oil inlet smoothly, but the fuel oil in the fuel tank also can vapor away from the gap between this screw thread, particularly when self-propelled vehicle stopped to travel, this also can cause the waste of fuel oil.
Summary of the invention
The purpose of this utility model is to provide a kind of volatilization prevention fuel tank that travels or stop to travel Shi Junke reduction fuel loss.
For achieving the above object, the utility model can be taked following technical proposals:
Volatilization prevention fuel tank described in the utility model, comprise casing that has oil inlet and the loam cake that has negative thread that is screwed on the described oil inlet, the tank wall of described casing is made of internal layer and skin, is filled with warm material in described internal layer and the outer interlayer that surrounds; Be horizontally set in the casing and floating cover that the middle part offers fuel feed hole slides up and down along the guide piece in the described casing.
Described guide piece is the vertical chute/guide pillar that is symmetricly set on the wall box, and the slide block/draw-in groove of described floating cover side and described vertical chute/guide pillar are complementary.
The roof inboard of described loam cake is placed with the flexible sealing liner, seals to extend in fuel feed hole from described upward lid top wall outside to be provided with air inlet pipe, is positioned at the outer air inlet pipe of lid top wall and is provided with breather cheek valve.
Described breather cheek valve is electromagnetic valve or hand valve.
On the lateral wall of described loam cake, extend and be provided with lever.
Advantage of the present utility model is simple in structure, volume compact, and is easy to use, and anti-fuel oil volatilization effect is remarkable.The warm material that is filled in the inside and outside interlayer can make the fuel oil in the casing be in stable low-temperature condition, and the evaporation rate of fuel oil is slowed down; And be in the area of contact that floating cover on the fuel oil face can reduce fuel oil and air all the time, also can effectively reduce the volatilization of fuel oil.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the enlarged drawing at oil inlet place among Fig. 1.
The specific embodiment
As shown in Figure 1, volatilization prevention fuel tank described in the utility model, comprise casing that has oil inlet 1 and the loam cake that has negative thread 2 that is screwed on the oil inlet, for making the fuel oil in the casing be in lower temperature all the time, the tank wall of casing is made of internal layer 3 and outer 4, is filled with warm material 5(warm material and can adopts asbestos in internal layer 3 and outer 4 interlayers that surround); For reducing the area of contact of fuel oil and air, place to be horizontally set in the casing on the fuel oil face and floating cover 7 that the middle part offers fuel feed hole 6 slides up and down along the guide piece in the casing.
For making its structure simple more compact, guide piece is four vertical chutes or the guide pillar that is symmetricly set on the wall box, the slide block of floating cover 7 dual-sides or vertical chute or the guide pillar on draw-in groove and the sidewall are complementary, can guarantee fuel oil in use, the floating cover 7 that is positioned on the fuel oil face moves up and down along vertical chute or guide pillar on the sidewall.
As shown in Figure 2, the air loss of fuel oil when guaranteeing that self-propelled vehicle stops to travel, roof inboard at loam cake 2 is placed with flexible sealing liner 8, goes up the lid top wall outside certainly and seals to extend in fuel feed hole and be provided with air inlet pipe 9, is positioned at lid top wall air inlet pipe outward and is provided with breather cheek valve 10; For satisfying the demand of all kinds of motor vehicle oil tanks, breather cheek valve 10 is electromagnetic valve or hand valve; Extension is provided with lever 11 on the lateral wall of loam cake 2, can make screw between loam cake 2 and the oil inlet 1 tighter, has guaranteed sealing effectiveness.
When in fuel tank, refueling, loam cake 2 is screwed from oil inlet 1, fuel oil enters in the fuel tank chamber by the fuel feed hole 6 at oil inlet and floating cover 7 middle parts, floating cover 7 can adopt the oil resisting material manufacturing of lightweight, guarantee its all the time floating head on the pasta of fuel oil, cover loam cake 2, use lever 11 that loam cake 2 is formed excellent sealing by flexible sealing liner 8 and oil inlet 1, during vehicle ', breather cheek valve 10 on the air inlet pipe 9 that loam cake 2 roofs enter is opened (suction quantity of adjusting air inlet valve 10 is suitable), outside air can enter in the fuel tank chamber from air inlet pipe 9 smoothly, eliminates the negative pressure that produces in fuel tank owing to fuel oil consumption; Simultaneously because floating cover 7 with pasta carry out actv. floating head, reduced the area of contact of pasta and air because warm material 5 is under the lower temperature fuel oil all the time this moment, reduced the volatilization of fuel oil in the motor-driven vehicle going process, saved fuel oil; When self-propelled vehicle stops to travel, breather cheek valve 10 is closed the waste that to have avoided fuel oil to volatilize voluntarily and cause by the automatic or manual mode.
