The function of valve pump

When the valve plug of valve pump shifts most interior limit onto, the ring grain sealing ring of annular groove is held to enter the bigger diameter end of the valve pump housing, The lumen in the space of bigger diameter end and valve plug is open-minded；At this point, the ring grain sealing ring of interior annular groove enter it is close in the middle part of the valve pump housing Section is sealed, the space of the lumen of valve plug and miner diameter end is closed.When the valve plug of valve pump is pulled to outermost limit, the ring grain of annular groove is held Sealing ring enters the seal section in the middle part of the valve pump housing, and the lumen of the space of bigger diameter end and valve plug is closed；At this point, interior annular groove Ring grain sealing ring enters the miner diameter end of the valve pump housing, and the space of the lumen of valve plug and miner diameter end is open-minded.When the valve plug of valve pump is set When most interior limit is among outermost limit, the ring grain sealing ring of the ring grain sealing ring and interior annular groove of holding annular groove is simultaneously in valve Seal section in the middle part of body simultaneously closes off the space in the space and miner diameter end of the lumen of valve plug and bigger diameter end.

When valve pump group is attached to fuel tank, the major diameter end spaces of valve pump are connected to oil storage bag, path end spaces and fuel tank outside The connection of portion space；Pump match is extracted when oiling, operation valve plug can convert the outside of valve plug lumen and oil storage bag, fuel tank as needed The on-off in space；Valve plug and pump match are operated, valve plug and the cooperation of pump match can exclude the residual gas in oil storage bag.

The operation of the oiling and exhaust of inside bag type fuel tank

When fuel tank refuels for the first time, the valve plug that valve pumps is pushed into most interior limit, pump plug is extracted, by the gas vacuum in oil storage bag Valve plug after so that the volume of oil storage bag is gone to zero, is pulled to interposition insertion refueling nozzle, the oil inlet of refueling nozzle and valve plug is close by discharge Envelope connection, then valve plug is pushed into most interior limit and is refueled, oil enters oil storage bag by oil-through hole；When that will fill it up with, in oil storage bag Residual gas is gathered in oil inlet and extracts refueling nozzle, and the bleed screw in release oil pump storehouse is twisted after draining the gas in oil pump storehouse at this time Close envelope；The oil inlet of refueling nozzle and valve plug is not closed to fill it up with oil, and the residual gas in oil storage bag drains, and is inserted into pump plug at this time Full push-in and by fuel tank cap locking.

Valve plug is pulled to interposition when refueling again, pump plug is extracted, refueling nozzle is inserted into, the oil inlet of refueling nozzle and valve plug It is closed；Valve plug is pushed into most interior limit again to refuel (fill it up with do not fill it up with all can), is added and valve plug is pulled to interposition after oil is extracted Refueling nozzle is inserted into pump plug, pump match, valve plug is pushed into entirely, locking fuel tank cap.

When gas is mixed into oil storage bag, the method that excludes gas:

It is pumped because mixed gas flow is small with valve and excludes gas manually.Concrete operations are as follows:

The valve plug that valve pumps is pushed into most interior limit, is pulled outwardly pump plug close to range, then valve plug is pulled to outermost limit It is pushed into pump plug, the intraluminal gas of valve plug is discharged；It slightly pauses and repeats above-mentioned movement, until valve when valve plug is pulled to outermost limit There is oil in plug lumen, then valve plug is pushed into most interior limit, then be pushed into pump match the oil injection oil storage bag in valve plug lumen, then by valve Plug is pulled to the full push-in pump match of outermost limit and the gas remained in valve plug lumen is discharged, locking fuel tank cap.

The setting of oil storage bag volume is greater than the volume of fuel tank, therefore fuel tank bears tension and oil storage bag and is solely subjected to oil and fuel tank To the pressure of composite membrane, the active force on composite membrane two sides tends to balance for wall and atmosphere, and it is just not tearable to be not subject to tension composite film. The Inner structural shape of fuel tank setting assembles the gas in oil storage bag to oil filler.The volume of extrusome, which is set greater than, to be equal to The maximum swelling volume of oil mass when minimum volume filler tank when extrusome is shunk is full oily.

The operating method of setting and the oiling and exhaust of Oiltank structure makes the gas in oil storage bag go to zero；Fuel tank ventilation The setting in hole makes the warehouse in oil pump storehouse, the utricule of oil storage bag while the pressure for bearing atmosphere, and the warehouse in oil pump storehouse is that rigidity is born Oily conducting pressure of the pressure of atmosphere not into warehouse, oily conducting pressure of the atmospheric pressure that oil storage bag is born into oil storage bag, So that the oil in oil storage bag flows to oil pump storehouse under the action of atmospheric pressure, the fuel feeding continual and steady to oil pump ensure that.

Core of the invention is to have used the enclosed soft package characteristic of fluid, be additionally arranged the corresponding portions such as oil storage bag, valve pump The rigidity of part and fuel tank body has been implemented in combination with the improvement to crude oil case.(fluid-tight flexible package characteristic: in atmospheric pressure and fluid The volume of enclosed soft package corresponds to the volume change of fluid and changes under the action of tension, volume from zero to maximum setting value, Again from maximum setting value to zero repeated transformation, without gas-phase space between fluid and flexible package, fluid is non-volatile not to be produced with atmosphere Raw convection current.)

Invention achieves do not generate oil vapour, liquid level gas-phase space and fire probability all go to zero, no matter how many oil all In saturation storing state, no matter the sealed storage state that oily volume dilational and atmosphere is in without convection current, always makes atmosphere pair The oxidation and pollution of oil and oil all go to zero to the pollution of atmosphere, oily quality and quantity has and preferably protects, eliminates oil vapour Recovery structure.

The beneficial effects of the invention are as follows in fuel tank oil with air is contactless, has blocked moisture pair in pollutant and atmosphere The intrusion of oil makes to tend to non-volatile state without ponding, oil in oil to tend to pollution-free, fuel tank to atmospheric environment and eliminate oil vapour to return Receiving apparatus, when refueling it is excessive without oil vapour, so that the class of risk of the oil of fuel tank is improved safety to combustible grade is close from firing grade Property.
