The factors such as summer quick-fried Sai, the setting of the pressure can use for example, under 50 degrees Celsius fire-retardant intracavity gas pressure as benchmark, this
The advantage of sample invention is more prominent, because combustion explosion, fire-retardant intracavitary gas pressure easily occur for fuel tank in summer high temperature season
Therefore Li Genggao when fire-retardant chamber deformation is smaller, that is, can trigger safety valve and open, guarantee fire-retardant gas release, and when winter is low
When the warm season, fuel tank is not susceptible to combustion explosion, and fire-retardant intracavitary gas pressure is smaller) 1/3, once one of them fire-retardant chamber
Safety valve open, in inert gas by rapid dilution fuel tank air and gasoline volatilization at oil gas.For example, can be with
Less than 3 standard atmospheric pressures of cracking pressure of the safety valve of adsorbent chamber are set, 2 standard atmospheric pressures are greater than.Certainly, as needed
In the case where improving fire-retardant intracavitary inert gas content, the cracking pressure of adsorbent chamber safety valve can be improved, avoid error starting.
According to above-mentioned fire-retardant intracavitary gas pressure setting, once any one fire-retardant chamber is opened, the gas pressure in fuel tank can be fast
Speed reaches 3 atmospheric pressure or more, in turn, while the safety valve of two adsorbent chambers is opened, due to being initially vacuum shape in adsorbent chamber
State, after adsorbent chamber is opened, the mixed gas of oil gas, inert gas and air in fuel tank can respectively enter two adsorbent chambers,
The adsorbent material of adsorbent chamber can adsorb oil gas, and oxygen flammable in gas and oil gas contains in further dilution fuel tank
Amount.
Benefit of the invention is that the gasoline in fuel tank is more, then flame-proof explosion-proof effect of the invention is better.This is because
When the gasoline in fuel tank is more, in remaining air it is fewer, and due to fire-retardant intracavitary fire-retardant gas content be it is fixed,
, can be rapidly by the air extrusion to adsorbent chamber in fuel tank in this way, once fire-retardant chamber is opened, and enable to lazy in fuel tank
The pressure and ratio of property gas are higher.
Present inventor's discovery when the case of the combustion explosion to automotive oil tank is studied, actually largely
The case where fuel tank burning or explosion is not to crash because fuel tank is integrally collided, and only fuel tank and extraneous junction are sent out
Raw light or heavy leakage simultaneously encounters burning caused by extraneous open fire or engine high-temperature part, and then burning is related rapidly causes
Gasoline combustion in fuel tank, and if oil gas in fuel tank can be blocked to be connected to the initial of the external world, it can effectively avoid this feelings
The generation of condition.Method of the invention is being collided initially aiming at such case, rapidly simultaneously by the fuel gas dilution in fuel tank
Completely cut off using inert gas, also, buffered in the position that fuel tank is easily collided setting protruding parts, first by fire-retardant chamber and
Adsorbent chamber bears deformation, excites fire-retardant and explosion-proof effect, the safety of dual guarantee fuel tank after bearing deformation.
The present invention passes through the cracking pressure that fire-retardant chamber and adsorbent chamber is cleverly arranged, so that after the deformation of fuel tank side, energy
Enough while two even more adsorbent chambers, the oxygen content in effective dilution fuel tank shoe cream room are triggered, and adsorbed in air
Oil gas, inhibits the volatilization of oil gas by high pressure, and multiple effect develops simultaneously effectively explosion-proof.
Fig. 5 is a kind of left view structural representation of structure of fire-resistant oil tank of the present invention.
The safety valve of fire-retardant chamber unlatching when the deformation of fire-retardant chamber reaches predetermined threshold, for example, the safety valve can use
Voltage-controlled safety valve is realized when fire-retardant chamber makes the volume in it reduce and reache a certain level because colliding the degree that deformation occurs
It opens.For example, the secure threshold of the safety valve of fire-retardant chamber can be set as to its pressure ascensional range is more than former pressure 1/3,
Once the safety valve of one of them fire-retardant chamber is opened, in inert gas by the air and gasoline volatilization in rapid dilution fuel tank
At oil gas.The cracking pressure of the safety valve of adsorbent chamber is less than the average pressure in a fire-retardant chamber release rear fuel tank, for example, 2
A standard atmospheric pressure is greater than 1.5 standard atmospheric pressures.Certainly, as needed in the feelings for improving fire-retardant intracavitary inert gas content
Under condition, the cracking pressure of adsorbent chamber safety valve can be improved, avoid error starting.It is set according to above-mentioned fire-retardant intracavitary gas pressure
Fixed, once any one fire-retardant chamber is opened, the gas pressure in fuel tank can be rapidly reached 2 atmospheric pressure or more, in turn, open simultaneously
The safety valve for opening multiple adsorbent chambers, due to being initially vacuum state in adsorbent chamber, after adsorbent chamber is opened, oil gas in fuel tank,
The mixed gas of inert gas and air can respectively enter two adsorbent chambers, and the adsorbent material of adsorbent chamber can inhale oil gas
It is attached, the content of oxygen flammable in gas and oil gas in further dilution fuel tank.
Benefit of the invention is that the gasoline in fuel tank is more, then flame-proof explosion-proof effect of the invention is better.This is because
When the gasoline in fuel tank is more, in remaining air it is fewer, and due to fire-retardant intracavitary fire-retardant gas content be it is fixed,
, can be rapidly by the air extrusion to adsorbent chamber in fuel tank in this way, once fire-retardant chamber is opened, and enable to lazy in fuel tank
The pressure and ratio of property gas are higher.
It should be noted that in order to which the volume in the fire-retardant chamber in two sides and vacuum chamber is drawn relatively small, reality by beauty in figure
In in order to guarantee flame-proof explosion-proof quality, need suitably to increase the volume of vacuum chamber and fire-retardant chamber, specifically set according to actual needs
It is fixed.
It is initial in collision in the present invention, the fuel gas in fuel tank is diluted rapidly and inert gas is utilized to completely cut off, also,
It is buffered in fuel tank sidewall setting protruding parts, deformation is born by fire-retardant chamber and adsorbent chamber first, is swashed after bearing deformation
Send out fire-retardant and explosion-proof effect, the safety of dual guarantee fuel tank.
The present invention passes through the cracking pressure that fire-retardant chamber and adsorbent chamber is cleverly arranged, so that after the deformation of fuel tank side, energy
Enough while two even more adsorbent chambers, the oxygen content in effective dilution fuel tank shoe cream room are triggered, and adsorbed in air
Oil gas, inhibits the volatilization of oil gas by high pressure, and multiple effect develops simultaneously effectively explosion-proof.
(Fig. 5 is left view, and Fig. 6 is to overlook) as shown in figures 5-6, it is highly preferred that the vacuum chamber and the shoe cream room it
Between side wall preferential subsidence area (corrugated portion in figure), the fold of the preferential subsidence area setting predetermined shape, the pleat are set
Wrinkle can pressure be more than in the case that predetermined value is unfolded towards vacuum chamber later, allow for shoe cream room dilatation.When fuel tank is by tight
Again squeeze in the case where, for example, a vehicle by truck from side impact, then fuel tank side will be deformed, this impact
The tolerance range of intensity far super usual fuel tank, at this time, on the one hand, due to fuel tank reserved towards interior side it is certain
Cushion space provides one layer of buffering, and on the other hand, after fuel tank cushion space is tied up completely, fuel tank necessarily deforms,
Then at this point, the vacuum chamber of top and front and rear sides and shoe cream room be by preferential subsidence area interval, so, the side of shoe cream room
Wall is collapsed to vacuum chamber, is reduced gasoline and is leaked possibility.
