Working principle:
When refueling nozzle refuels to fuel tank, the liquid level in fuel tank is constantly increased, at this time under the pulling force of the first spring 4, first
The upper end of float 5 and first row stomata 7 are detached from, and the oil gas in fuel tank enters exhaust passage 1.3 through first row stomata 7 and is discharged；Oil
When liquid level continues to increase in case, oil liquid enters in fluid level control valve through the first oil filler 8, and the first float 5 is by oil liquid at this time
Buoyancy overcomes the pulling force of self gravity and the first spring 4 to rise, and the first float 5 blocks first row stomata 7 and forms sealing, oil
Oil gas, which cannot be discharged, in case causes tank pressure to increase, and refueling nozzle jumps rifle, refuels and stops, liquid level is exactly in fuel tank at this time
The closing height of fluid level control valve
It refuels after jumping rifle, to carry out adding oil, under the pulling force of second spring 11, the upper end and second of the second float 12
Gas vent 14 is detached from, and oil gas enters exhaust passage 13 by second row stomata 14 and is discharged in fuel tank, and it is logical that Tipping valve provides exhaust
Road；When adding oil to a certain extent, oil liquid enters in Tipping valve through the second oil filler 16, and the second float 12 is by oil at this time
The buoyancy of liquid overcomes the pulling force of self gravity and second spring 11 to rise, and the second float 12 blocks the formation of second row stomata 14
Sealing, tank pressure further increase, and refueling nozzle is forced to stop, therefore prevents refueling from occurring.
In normal vehicle operation, when tank internal pressure is excessive, oil gas is through second row stomata 14 by second in fuel tank
Valve 13 opens, and then oil gas enters carbon tank valve through exhaust pipe 1.3 to keep tank pressure to balance.
Vehicle is under the gradient, the special statuss such as overturning, the first valve 15 of fluid level control valve and the second valve of Tipping valve
13 can all close and prevent from leaking.
When coping with different clients demand, it is only necessary to individually adjust fluid level control valve and Tipping valve, built-in Liquid level
Valve, it is only necessary to which liquid level closing height, fluid level control valve can accurately be adjusted by adjusting 8 height of the first oil inlet on fluid level control valve
The oil inlet of valve shell mold is set as replaceable loose plug, that is to say, that same pair mold, the height of oil inlet can
With flexible modulation；Built-in Tipping valve closes height can be by adjusting the weight of the second float 12 and the stiffness system of second spring 11
It counts to meet the demand of client, while the closing height of built-in Tipping valve and fluid level control valve can be according to different specified oilings
The requirement of volume and delivery space adjusts.
