In conclusion compared with prior art, when the present invention uses: the refueling process of refueling nozzle is as follows, the drive of 9 triggers is pushed away
Linkage 4 is mobile, and main valve 7 is opened under oil pressure effect, and controls refueling nozzle stream apart from aperture with the movement of transfer bar mechanism 4
Through 7 channel of main valve, gun body asphalt channel 14, vacuum secondary valve 3 occurs for amount, asphalt channel of the oil liquid through mechanical ratio adjusting valve 8
Oil circuit main channel, then automotive oil tank is injected through gun barrel main channel;Oil gas getter cover 1 is locked with fuel oil gun body front end with hose clamp,
Elasticity by oil gas getter cover 1 is sealed;The oil gas of automotive oil tank volatilization secondary oil gas recovery pump in dispenser system produces
Under raw vacuum condition, gas station is returned to by oil gas getter cover 1, gun body asphalt channel 14, mechanical ratio adjusting valve 8 etc.
In oil storage tank pipe, petroleum vapor recovery function is completed.
When by vacuum secondary valve 3 occurs for oil stream, since oil pressure acts on 105 compression cone spring 106 of steel ball, spool 104 is pressed
Contracting spring 107, the two open simultaneously and allow oil stream to pass through and enter fuel-displaced tube assembly 2.Oil stream enters valve body through secondary valve port 108
Negative pressuren zone is formed when 103 conical opening at the first gun body channel 109, the oil gas to volatilize there are automotive oil tank due to negative pressure can be through
Fuel-displaced tube passage 113 and third gun body channel 112 enter negative pressuren zone, form interior circulation through the first gun body channel 109 injection oil stream.
When oil gun stops refueling, reset condition locating for volute spring 106 and steel ball 105, when shooting to refuel, oil stream comes
Afterwards, since oil pressure acts on, on the steel ball 105 of oil pressure effect, compressed spring 106, oil stream can pass through bellmouth.Effect is oil gun
When stopping refueling, steel ball 105 can be sealed with the inner hole of spool 104, avoided closing and robbed rear oil liquid outflow.
When automotive oil tank is filled it up with, fuel-displaced tube passage 113 is sealed by fuel tank inner fluid, and negative pressuren zone is through the first gun body channel
109 and second gun body channel 110 extract 6 overhead gas of air chamber component, make at air chamber component 6 formed negative pressure, negative pressure be greater than second
When 202 pressure of spring, second spring 202 is compressed, and the first needle roller 203 of air chamber component 6 is driven to move upward out transfer bar mechanism 4
Groove occurs to jump rifle, i.e. the reset of transfer bar mechanism 4 closes main valve 7 and stops refueling.
In normal refuel, for oil gun mouth towards reservoir port, steel ball 603 fits to 601 end faces under the effect of gravity, self-styled logical
Road is normally opened, and oiling is normally carried out.When gun body outlet is higher than level, when being in upward heeling condition, steel ball 603 can be because of gravity
Effect rolls, and vacuum occurs secondary 3 air intake passage of valve and is blocked, and oil gun is equally because gas chamber spring is occurred to jump rifle by compression.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features,
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
