Abstract
The invention discloses the upper box structure of fuel tank, comprise fuel tank upper box (1), fuel tank upper box (1) is provided with multiple safety valve positioning port, and each safety valve positioning port is provided with a safety valve (2), multiple safety valve (2) is connected in turn by connection pipe (3).The present invention adopts said structure, integral structure is simple, is convenient to realize, and can carry out pressure release to the pressure in fuel tank by safety valve (2) when the present invention applies, this can be avoided metal fuel tank to damage because of hypertonia, is so convenient to applying of metal fuel tank.
Description
Technical field
The present invention relates to vehicular spare parts, specifically the upper box structure of fuel tank.
Background technology
Along with development and the development of auto-industry, the use amount of automobile increases, and as the critical component of vehicle fuel feed system, the demand of fuel tank of vehicle also increases.The lower box that existing automobile metal tank assembly comprises upper box and is tightly connected with upper box, when fuel tank internal pressure is too high, the sealing property of fuel tank can be damaged, from fuel tank, fuel oil can occur that the position in crack is released, just there is larger potential safety hazard in this, and then can have influence on applying of metal fuel tank.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide one and can carry out pressure release to fuel tank automatically when fuel tank internal pressure is too high, and then fuel tank can be avoided to occur the upper box structure of the fuel tank in crack.
Object of the present invention is achieved through the following technical solutions: the upper box structure of fuel tank, comprise fuel tank upper box, described fuel tank upper box is provided with multiple safety valve positioning port, each safety valve positioning port is provided with a safety valve, multiple safety valve is connected in turn by connection pipe.In the present invention, multiple safety valve is the connection pipe quantity of emissions reduction fuel oil by the object that connection pipe is connected, and by fuel oil uniform effluent, is convenient to control the fuel oil of discharge.
Because the volume of fuel tank is comparatively large, for the ease of fast speed pressure release, assemble multiple safety valve in the present invention, as preferably, the quantity of described safety valve positioning port and safety valve is two.
Because fuel tank need fit tightly with vehicle body when applying, in order to cushion the application force of fuel tank and vehicle body and other part of Che Nei, described fuel tank upper box is connected with cushion blocking.
Described fuel tank upper box is provided with the compression leg that one end is connected with fuel tank upper box, and described compression leg sidewall contacts with cushion blocking upper surface.The present invention pushes down cushion blocking by under compression leg, and cushion blocking can be avoided further to come off.
Described fuel tank upper box is provided with fuel charger positioning port and sensor localization mouth.The present invention is when applying, and fuel charger is arranged on fuel charger positioning port, and sensor setting is on sensor localization mouth.
Compared with prior art, the present invention has following beneficial effect: fuel tank upper box of the present invention is provided with multiple safety valve, the keying of safety valve is subject to the impact of External Force Acting, when the present invention is applied on metal fuel box assembly, when fuel tank internal pressure is excessive, safety valve can be opened automatically, earial drainage is carried out to the liquid in fuel tank or gas, and then the pressure release completed fuel tank, fuel tank can be avoided to occur crack by the present invention, can not only eliminate safe hidden trouble, and be conducive to applying of metal fuel tank.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Name in accompanying drawing corresponding to Reference numeral is called: 1, fuel tank upper box, 2, safety valve, 3, connection pipe, 4, cushion blocking, 5, compression leg, 6, fuel charger positioning port, 6, sensor localization mouth.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
Embodiment:
As shown in Figure 1, the upper box structure of fuel tank, comprise metal fuel tank upper box 1, wherein, fuel tank upper box 1 is provided with multiple safety valve positioning port, each safety valve positioning port is provided with a safety valve 2, multiple safety valve 2 is connected in turn by connection pipe 3, and connection pipe 3 preferably adopts nylon hose.Safety valve 2 can adopt existing conventional safety valve, and it opens and closes by External Force Acting, and under atmospheric pressure state, it is in closed condition, when the pressure medium suffered by it is opened higher than safety valve during its setting value, and then carries out corresponding pressure release.As preferably, in the present embodiment, the quantity of safety valve positioning port is set to two, two safety valve positioning ports is arranged respectively a safety valve 2, and namely the quantity of safety valve 2 is also two.Fuel tank upper box 1 is provided with the fuel charger positioning port 6 for arranging fuel charger, and arranges the sensor localization mouth 7 of sensor.
Fuel tank upper box 1 is connected with cushion blocking 4, for the ease of the connection of cushion blocking 4 and fastening, fuel tank upper box 1 local inner concave is configured with groove, this groove inner wall is connected with compression leg 5, the vertical recess sidewall that it connects of compression leg 5, and the central part of cushion blocking 4 is arranged in this groove, compression leg 5 sidewall contacts with cushion blocking 4 upper surface, namely compression leg is pressed in for 5 times on cushion blocking 4, and as preferably, the quantity of compression leg 5 is two.
As mentioned above, then well the present invention can be realized.
