Technical field
The present invention relates to aircraft fuel system fields, more particularly to aircraft fuel tank volume read-out control technology.
Background technology
Aircraft fuel system generally has multiple fuel tanks, and fuel tank fills it up with fuel oil in flight in most cases, still,
In some cases the reason for (such as aircraft loading weight or position), according to different mission plannings, some fuel tanks need to set
Different volume read-outs to meet gravity's center control, and adapts to special flying condition requirement.
At present, the method for controlling fuel tank volume read-out is the method (water of similar water closet of pasta float+oil-way shutoff valve
Case full water control method).Using this method, a float can only control a kind of volume read-out pasta, if you need to multiple volume read-out pastas
Control, then need to set multiple floats, complicated, reliability is low, of high cost.
The content of the invention
The present invention realizes that a variety of volume read-outs of fuel tank automatically control in simple method, meets under particular case, fuel tank carries oil
Measure different requirements.
The present invention provides a kind of fuel tank oiling amount control devices, which is characterized in that including fuel tank (1), snorkel (2),
(3), oil filling pipe (4) are switched, oil filling pipe (4) is communicated with fuel tank (1)；
The nozzle of its Center Vent tube (2) one end is outer spout (6) outside fuel tank, and other end nozzle is stretched into fuel tank (1),
For inner spout (5)；
Inner spout (5) and the distance of top of oil-tank are H, and inner spout (5) and the distance H of top of oil-tank are adjustable, in snorkel
(2) switch (3) is set on, and switch (3) is in fuel tank external position.
The present invention provides a kind of fuel tank oiling amount control methods, which is characterized in that comprises the following steps：
A) the volume read-out pasta needed according to fuel tank, the method for taking snorkel (2) flexible set up inner spout (5) and oil
The distance H of box top；
B) switch (3) is opened, fuel tank (1) interior air is made to be connected with ambient atmosphere；
C) refueled by oil filling pipe (4) into fuel tank (1)；
D) fuel oil is into cartonning, while the air in fuel tank enters snorkel (2) from inner spout (5), and passes through outer spout (6)
It is discharged into air；
E) when fuel oil addition reaches requirement, pasta submergence inner spout (5), fuel tank (1) exhaust is interrupted, in fuel tank (1)
Surplus air compressed, generate back-pressure prevent fuel oil addition；
F) oil filling pipe (4) is closed, turns off switch (3), oiling terminates.
Advantages of the present invention：
Top of oil-tank sets snorkel, which can stretch, can so as to ventilate distance of the nozzle apart from top of oil-tank
With variation；Snorkel appropriate location sets switch, and control snorkel switches on and off.The length of snorkel is (logical in regulating oil tank
Distance of the gas tube orifice apart from top of oil-tank), the oiling energy of fuel tank can be controlled.
When fuel tank refuels, after fuel oil reaches predetermined volume read-out pasta, fuel oil submergence ventilation nozzle blocks blow vent,
At this point, the air on pasta top can not continue to discharge in fuel tank, be gradually compressed afterwards, generate back-pressure, prevent fuel oil continue into
Enter fuel tank, realize that fuel tank volume read-out automatically controls.
The present invention uses scalable snorkel, air back-pressure control fuel tank volume read-out, simple in structure, good reliability, service life
It is long, at low cost.

Outside, i.e. outer spout 6, other end nozzle is in fuel tank, i.e. inner spout 5；Inner spout 5 and the distance of top of oil-tank are H, in snorkel
Switch 3 is set on 2, and switch 3 is in fuel tank external position.Switch 3, which is opened, can make the inside and outside connection ventilation of fuel tank 1, and switch 3 is closed and can cut
Open close tracheae 2 makes 1 obstruction of QI between the interior and exterior stuffiness of fuel tank.The snorkel 2 can stretch, for this purpose, nozzle 5 and top of oil-tank distance H
It can change.Distance H is the volume read-out pasta that fuel tank needs control.
It further illustrates, operation principle of the present invention is as follows：
Top of oil-tank sets snorkel, which can stretch, can so as to ventilate distance of the nozzle apart from top of oil-tank
With variation；Snorkel appropriate location sets switch, and control snorkel switches on and off.The length of snorkel is (logical in regulating oil tank
Distance of the gas tube orifice apart from top of oil-tank), the oiling energy of fuel tank can be controlled.
When fuel tank refuels, after fuel oil reaches predetermined volume read-out pasta, fuel oil submergence ventilation nozzle blocks blow vent,
At this point, the air on pasta top can not continue to discharge in fuel tank, be gradually compressed afterwards, generate back-pressure, prevent fuel oil continue into
Enter fuel tank, realize that fuel tank volume read-out automatically controls.
