Description
Technical field
The utility model relates to vehicular spare parts, specifically a kind of fuel filler pipe assembly of counter-jetting resistance.
Background technology
Traditional fuel filler pipe assembly is generally formed by combining by fuel filler pipe, freeing pipe and mounting bracket, and wherein fuel filler pipe comprises the exhaust joint that oil filling port, oil outlet and oil filling port place arrange; One end of freeing pipe is quick connector, and its other end is communicated with the exhaust joint of fuel filler pipe.During oiling, the oil filling port of fuel filler pipe inserts oil gun, and its oil outlet is connected with the pouring orifice of fuel tank, and the quick connector of freeing pipe is connected with the deflation hole of fuel tank.Liquid fuel is in fuel filler pipe enters fuel tank, and fuel oil enters after fuel tank, and the air in fuel tank enters atmosphere through freeing pipe to exhaust joint by oil filling port from quick connector.
The gas that traditional fuel filler pipe assembly cannot be discharged fuel tank in refueling process cushions, in the moment of filling it up with oil jumping rifle, due to suction effect, air-flow at a high speed can be by the fuel oil in fuel tank from quick connector sucking-off in freeing pipe, and it is spouting by oil filling port through exhaust joint to enter freeing pipe.This phenomenon of regurgitating is filled it up with and in process, is refueled when too fast especially obviously at fuel tank, and fuel tank is not yet filled it up with even sometimes, and fuel oil just can be regurgitated from the oil filling port of fuel filler pipe, causes nozzle extremely to jump rifle.Regurgitating potential potential safety hazard, and cause energy dissipation, is also a kind of economic loss to customer, easily causes customer's complaint, and the problem of regurgitating in refueling process is anxious to be resolved.
For solving the problem of regurgitating, CN 201951233 U disclose and a kind of fuel tank of vehicle, this fuel tank is to be provided with the first pressure regulation breather hose and the second pressure regulation breather hose, to reach the object of trim tank body combustion pressure, and then overcome when adding fuel oil exhaust fuel oil insufficient and that cause and the series of problems such as regurgitate.Yet this scheme for be that fuel tank improves, for each automobile, cost is higher, and for the vehicle of having put on market, then it is also unrealistic to carry out fuel tank transformation.
Utility model content
The purpose of this utility model is to provide a kind of fuel filler pipe assembly of counter-jetting resistance, and it can solve in refueling process and cause fuel oil from the problem of the oil filling port ejection of fuel filler pipe owing to regurgitating.
The technical solution of the utility model is as follows:
A kind of fuel filler pipe assembly of counter-jetting resistance, comprise fuel filler pipe and freeing pipe, the exhaust joint that fuel filler pipe has oil filling port, oil outlet and is communicated with oil filling port, exhaust joint is communicated with one end of freeing pipe, the other end of freeing pipe has quick connector, described freeing pipe is serially connected with the buffering cavity that internal diameter is greater than freeing pipe internal diameter, in described buffering cavity, has been disposed radially porous barrier.
Further, on two end faces of described buffering cavity, be respectively arranged with an ozzle being connected with freeing pipe, described ozzle is positioned at the edge of buffering cavity end face, and two ozzles buffering cavity axially on shift to install.
Further, described buffering cavity is cylindrical, and it comprises two sections of cylindrical shells of open end phase tight weld, and the open end of cylindrical shell is provided with step, and described porous barrier is the circular slab that is evenly distributed with a plurality of air extractor vents, and porous barrier is spacing in the step of two cylindrical shells.
This programme arranges porous barrier and prevents that fuel oil from regurgitating out the problem of oil filling port by serial connection buffering cavity in freeing pipe and in buffering cavity.From the gas mixture of fuel tank sucking-off when arriving buffering cavity, be to be placed in from tiny gas exhaust duct moment the buffering cavity that inner product is larger, pressure is discharged, unlifting pressure reduces, and under the obstruct of porous barrier, Oil-gas Separation, fuel oil is retained in buffering cavity, gas continues to arrange outward along freeing pipe, thereby has avoided fuel oil to regurgitate out the phenomenon of oil filling port.And after air pressure and barometric pressure balance in fuel tank, the fuel flow returns oil sump tank in buffering cavity, in order to avoid cause damage to customer.
And by two ozzles buffering cavity axially on shift to install further guarantee that fuel oil is trapped within buffering cavity.And buffering cavity adopts the form of two sections of cylindrical shells docking, make porous barrier be easy to install, the processing and fabricating that makes to cushion cavity is easy to implement.
The utility model is simple in structure, easy to operate, is easy to realize, can effectively to the gas of discharging in refueling process or fuel oil, cushion, can stop the phenomenon that the fuel oil in refueling process is regurgitated out oil filling port, thereby reduce customer's economic loss, reach the object that promotes customer satisfaction.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
The fuel filler pipe assembly of a kind of counter-jetting resistance shown in Figure 1, comprise fuel filler pipe 1 and freeing pipe 2, during oiling, oil gun inserts the oil filling port 11 of fuel filler pipe 1, the oil outlet 12 of fuel filler pipe 1 is connected with the pouring orifice of fuel tank, the exhaust joint 13 that oil filling port 11 is communicated with is communicated with one end of freeing pipe 2, the other end of freeing pipe 2 has quick connector 21, quick connector 21 is connected with the deflation hole of fuel tank, buffering cavity 3 of freeing pipe 2 serial connection, and in buffering cavity 3, be disposed radially porous barrier 32 buffering cavity 3 is divided into two sections.When occurring regurgitating, while rising to the larger buffering cavity 3 of internal diameter from the gas mixture of fuel tank sucking-off along freeing pipe 2, due to the cushion space that provides of buffering cavity 3, the pressure of gas mixture is discharged, the pressure decreased rising, and under the stopping of porous barrier 32, fuel oil is trapped, gas continues to enter oil filling port 11 and be discharged to air environment through exhaust joint 13 along freeing pipe 2 through porous barrier 32.And after air pressure and barometric pressure balance in fuel tank, the fuel flow returns oil sump tank in buffering cavity 3, in order to avoid cause damage to customer.
On two end faces of described buffering cavity 3, an ozzle 31 is set respectively for connecting freeing pipe 2, and ozzle 31 is arranged on to the edge of buffering cavity 3 end faces, and two ozzles 31 buffering cavity 3 axially on shift to install, guarantee two ozzles 31 buffering cavity 3 axially on stagger completely.Like this, two ozzles 31 directly do not connect, and when regurgitating, even if unlifting pressure is larger, gas mixture can not directly be gone out the ozzle 31 of upper end from the ozzle 31 of lower end, further guarantee that fuel oil is trapped in buffering cavity 3.
Concrete, cylindrical buffering cavity 3 as shown in Figure 2, its shell is formed by the cylindrical shell 33 Butt sealing welderings of two sections of openings, and step 34 positions that the open end of cylindrical shell 33 is provided with after 33 welding of 34, two cylindrical shells of interior step are used for holding installation porous barrier 32.Correspondingly, porous barrier 32 is circular slab, and it is evenly distributed with a plurality of air extractor vents 35 and drains after for the gas overflowing in gas mixture.
Preferably, buffering cavity 3 can be serially connected in to the medium position of freeing pipe 2, and mounting bracket 4 be set on fuel filler pipe 1 with easy to use.
