Description
Technical field
The invention belongs to technical fields of refueling, and are to be related to a kind of fuel loading system more specifically.
Background technique
The car ownership in China increasingly increases, due to automobile caused by pollution condition also get worse.In each of automobile
Just there is an oiling emission pollutant in kind pollutant.General-utility car in refueling process, due to fuel oil directly with the external world it is big
Volatile organic compounds (volatileorganic compounds, abbreviation can be discharged in gas contact, fuel system to atmosphere
VOC), VOC is the preceding extract to form ozone, harmful to the health of environment and people.As people are to the cry of environmental protection
Growing day by day, national increasingly tight to auto emission standard day, refueling process exhaust emission is gradually paid attention to by people.It is existing
The technical solution that stage reduces refueling process exhaust emission is mainly:

Inclined-plane on the ontology of 11 ' of body will be blocked from 1116 ' of control lever, and when self-styled 116 ' of bar is moved up, 1115 ' of steel ball is i.e. to from control lever
1116 centers ', which are collapsed, to be made to move down from 1116 ' of control lever, makes switch that 1111 ' are lost fulcrum；
When fuel feeding, switch is 1111 ' using 1115 ' of steel ball, from 1116 ' of control lever, 116 ' of self-styled bar, oil gun main body 11 '
The fulcrum of ontology composition, overcomes the elastic force of 118 ' of the 6th elastic component, makes 119 ' pushing tow main switching valve of mandril, 117 ', main switching valve
117 ' are opened, and pressure oil enters the cavity in the ontology of 11 ' of oil gun main body between 117 ' of 1114 ' of auxiliary switch valve and main switching valve simultaneously
The elastic force of 1113 ' of the 7th elastic component is overcome to push 1114 ' of auxiliary switch valve open, oil liquid is discharged from 12 ' of gun adapter.Oil liquid flows through auxiliary switch
Siphonage when 1114 ' of valve due to liquid stream makes the 111 ' pressure reduction of seal chamber epicoele, but 111 ' of seal chamber epicoele passes through switching
It covers 114 ' inclined holes, 113 ' of air inlet pipe, 1112 ' of suction nozzle to communicate with the outside world, outside air is constantly supplemented in seal chamber epicoele
111 ', therefore 111 ' of seal chamber epicoele and the 112 ' pressure balance of seal chamber cavity of resorption, are atmospheric pressure.When volume read-out is enough to flood liquid level
When not having 1112 ' of suction nozzle, 111 ' of seal chamber epicoele is isolated from the outside world to form negative pressure, since 112 ' of seal chamber cavity of resorption is still atmosphere
Pressure, 115 ' of flexible sheet drives self-styled 116 ' of bar to move up under the action of draught head, so that 1115 ' of steel ball is got into automatic control bar
In 1116 ', moved down from 1116 ' of control lever in the case where switching the pulling force effect 1111 ', 117 ' of main switching valve is in 118 ' of the 6th elastic component
Closing oil passage is moved down under elastic force effect, thus fuel cut-off；It can be seen that conventional gasoline rifle is to realize jump using negative pressure
Rifle.

300 oil filler end face fitting, therefore oil circuit still maintains the state with ambient atmosphere isolation.
Such as Figure 10, as gun adapter 12 continues to protrude into oil filling pipe 300, the first sealing cover 13 opened by gun adapter 12 starts
Pushing tow control-rod 33, the control-rod 33 by pushing tow overcome 34 elastic force of the 5th elastic component to move up and control lock 35 toward closing direction
Rotation, until the first sealing cover 13 is resisted against opening and closing 18 rear of valve, the first sealing cover 13 is maintained at same angle, control at this time
Bar 33 is maintained at same height, and lock 35 is then detained the first sealing cover 13 and lockked, so that the first sealing cover 13
The fixed entirety with one closing of the composition of oiling tube body 31.
Such as Figure 11, the first sealing cover 13 is moved back relative to oiling gun body 10, when the first sealing cover 13 reaches support base 14 fastly
When place, the first sealing cover 13 is contacted with locating button 16 first, and the first inclined-plane 162 and the second inclined-plane 132 cooperate.It positions at this time
Button 16 is resisted against at top dead centre under the effect of 17 elastic force of third elastic component.
Such as Figure 12, the first sealing cover 13 pushes locating button 16, since the effect on inclined-plane is so that locating button 16 overcomes third bullet
The elastic force of property part 17 moves down, and the first sealing cover 13 continues to promote.
Such as Figure 13, locating button 16 is caught in the groove of the first sealing cover 13 under the effect of 17 elastic force of third elastic component, at this time
It can stop the movement that refueling nozzle protrudes into oil filling pipe, first sealing cover 13 is resisted against fixed under the elastic force effect of the second elastic component 15

The fixed entirety of 11 threes composition, one closing will continue to keep internal oil passages and ambient atmosphere isolation decontroling refueling nozzle
State, without to reach sealing effect and always to refueling nozzle applied force in refueling process.
Such as Figure 14, when oiling finishes, locating button 16 (button for facilitating pressing can be set on locating button 16) only need to be pressed,
Not by the constraint of locating button 16,15 pushing tow support base 14 of the second elastic component consolidates integrated first sealing cover 13 with support base 14
Oil gun main body 11 is moved back with respect to the oil filler of the first sealing cover 13, oil filling pipe 300, and gun adapter 12 starts to extract oil filling pipe.
Extract on the way, due to 32 end of the second sealing cover of oil filling pipe inclined-plane respectively with the inclined-plane of 12 end of gun adapter,
The inclined-plane at 18 top of opening and closing valve interacts and squeezes and push away the second sealing cover 32, and gun adapter 12 is smoothly exited.Oil filling pipe simultaneously
Second sealing cover 32 rotates under the action of the torsional spring of hinged place toward closing direction, releases the constraint to control-rod 33, control-rod 33
It is moved down under the effect of 34 elastic force of the 5th elastic component, lock 35 is driven to rotate toward opening direction, to release to the first sealing cover 13
It is locked, but first sealing cover 13 is still kept and the oil filler end face of oil filling pipe 300 under the action of the second elastic component 15 at this time
Fitting, until being finally restored to state shown in Fig. 8.
Such as Fig. 5, the canister desorption valve 231 on canister 23 is under the control of engine control module in suitable operating condition
It opens, forced ventilation desorption is implemented to canister 23.Breather check valve 24 can only be opened when the air pressure in fuel tank body 21 is too low, be allowed
Ambient atmosphere, which is supplemented in, to be come, and the oil gas in fuel tank body 21 cannot be allowed to release outward.Due to refuel when oil filling pipe 300 oil filler with
Sealing, thus oil gas can only gap between gas channel 22 and cone valve 28 through oil gas check valve 27 flow into canister 23, in carbon
Toward extraneous discharge purified gas after being adsorbed in tank 23.Cone valve 28 is fixed on 26 top of float, in float bracket 25
Constraining lower float 26 can only be along fixed axis upper and lower translation.The shape and cone valve 28 of 22 end inner hole of gas channel cooperate.

The gap formed between 22 end inner hole of cone valve 28 and gas channel is obtained to continue gently to reduce until cone valve 28 is completely by oil gas
Channel 22 is closed, and this measure can largely pour in canister 23 to avoid oil gas in a short time, causes canister 23 to work overloadingly, together
Shi Yike plays the role of limiting volume read-out.
Such as Fig. 8, after completely gas channel 22 is closed in cone valve 28, if continuing to refuel into fuel tank body 21 at this time, it is bound to
It will cause air pressure P1, P2 to steeply rise, then cannot achieve according to traditional refueling nozzle and jump rifle function, therefore relative to traditional
Refueling nozzle, the 111 reconfiguration ambient atmosphere of seal chamber epicoele in refueling nozzle of the present invention, and 112 reconfiguration oil gun main body of seal chamber cavity of resorption
Inclined hole on 11, the inclined hole on reducing sleeve 114, air inlet pipe 113, suction nozzle 1112 are identical as the P2 in oil filling pipe.When P2 rises
After to a certain extent, the pressure difference between seal chamber cavity of resorption 112 and seal chamber epicoele 111 is enough to drive flexible sheet 115 and oneself
Envelope bar 116, which moves up, gets into steel ball 1115 in automatic control bar 1116, and switch loses fulcrum 1111, realizes and jumps rifle.
After oiling, liquid level during automobile consumption gasoline in fuel tank can be gradually reduced, and float 26 is with mantle
Valve 28 moves down therewith, starts to open wide between cone valve 28 and gas channel 22, fuel tank body internal pressure value be P1 high-pressure oil gas therefrom
Release is into canister 23, but liquid level under the action of pressure value is the high-pressure oil gas of P2 at the oiling tube body 31 at float 26 is rapid
Rise, drives float 26 that cone valve 28 is made to close gas channel 22, stopped oil gas releasing toward canister 23.Until in fuel tank body 21
Gasoline continue consumption, liquid level and just repeat above-mentioned movement when beginning to decline some again, such circulation.This measure can exist to avoid oil gas
Canister 23 is largely poured in short time, and canister 23 is caused to work overloadingly.
