To meet helicopter fuel tank ventilation demand, present applicant proposes a kind of automatic exhaust steam valves.The automatic exhaust steam valve can
For the venting communication between different fuel tanks, for meeting when fuel tank oiling, oil pumping and helicopter flight attitude change
Ventilation requirement.
As depicted in figs. 1 and 2, the automatic exhaust steam valve of the application mainly includes shell 1 and floating drum 2, has phase in shell 10
Intercommunicated first passage 111, second channel 121 and third channel 122 is equipped with top on the side wall top of first passage 111
Exhaust outlet 112 is equipped with base bleed hole 123 in the side wall of third channel 122, and floating drum 20 is set to the third channel of shell 10
In 122, and floating drum 20 opposite with third channel 122 can slide, for blocking or opening third channel 122, air or fuel oil
It can be from flowing.Top vent 112 and base bleed hole 123 flow into first passage 111, second channel 121 and third channel
In 122.
In this application, the shell 10 of automatic exhaust steam valve is a three-way connection, the first passage 111 and third having
122 axis collinear of channel, and the axis of second channel 121 is perpendicular to first passage 111 or the axis of third channel 122.Three
In pass joint, the port of second channel 122 is that spherical surface connects mouth, connect with vent line (outside fuel tank), first passage 111 and
Third channel 122 is placed in fuel tank.
In one embodiment of the application, shell 10 is split type structure, is made of upper housing 11 and lower case 12, upper casing
Body 11 is shorter tube shape, and top vent 112 is disposed thereon, and lower case 12 is three-port structure, and the setting of base bleed hole 123 exists
On a certain channel, the shorter channel of lower case 12, this channel and the channel with base bleed hole 123 is arranged in upper housing 11
Coaxial line, upper housing 11 and lower case 12 use the relatively fixed mode being threadedly coupled to constitute shell 10.
In above-described embodiment of the application, sealing ring 13 is equipped between upper housing 11 and lower case 12, for sealing
State shell 10.
In this application, in order to carry out quickly discharge and sucking to the gas in fuel tank, setting is on the housing 10
Top vent 112 be it is two or more, uniformly distributed with the axis of first passage 111, base bleed hole 123 can simultaneously two
Or it is multiple, it is uniformly distributed with the axis of third channel 122.
In this application, in order to which gas or liquid is discharged, there is gap 124 between third channel 122 and floating drum 20,
Gap 20 is connected to second channel 121 and base bleed hole 123.
In this application, sealing cup 15 is equipped with inside third channel 122, sealing cup 15 is used in floating drum 20 by fuel oil
When picking-up, cooperate with floating drum 20 to block the gap 124 and base bleed hole 123 of third channel 122.
In this application, in order to float floating drum 20 can in fuel oil, the density of floating drum 20 answers small fuel oil
Density.It should be noted that this light material system of such as foam can be used under the premise of floating drum 20 can float
At, can also using density be greater than fuel oil metal material but inner hollow by the way of.
In addition, present invention also provides a kind of fuel tank systems comprising above-mentioned automatic exhaust steam valve can be used for different oil
Venting communication between case, can meet plus, oil pumping and helicopter flight attitude change when ventilation requirement.
The fuel oil refueling process of the fuel tank system of the application is as follows:
As shown in figure 3, when oil mass is lower, floating drum 20 does not float, and the air in fuel tank can lead in refueling process
It crosses top vent 112 and base bleed mouth 123 enters in automatic exhaust steam valve, and fuel tank is discharged by second channel 121.
As shown in figure 4,20 buoyancy of floating drum increases when fuel oil is added to a certain degree, floating drum 20 rises and and sealing cup
15 closures, so that the gap 124 between third channel 122 and floating drum 20 and base bleed mouth 123 are blocked, thus fuel tank
Air only can pass through top vent 112 be discharged fuel tank.
As shown in figure 5, when oil mass continues to increase to fuel tank head, fuel oil can flow into the by top vent 112
Inside one channel 111 and second channel 121, fuel tank fills it up with fuel oil at this time, and stops refueling.
The fuel consumption or oil pumping process of the fuel tank system of the application are as follows:
As shown in figure 5, floating drum 20 is opened under differential pressure action in the initiating process that fuel tank consumes or pumps, the
Fuel oil in two channels 121 can enter fuel tank by top vent 112 under the action of pressure difference.
As shown in fig. 6, continuing in consumption process in fuel oil, when second channel 121 is unimpeded, air passes through top vent
112 enter fuel tank, and floating drum 20 and sealing cup 15 are closed, at this time can some fuel oils of remaining in shell 1.
As shown in fig. 7, continue in consumption process in fuel tank, with the reduction of fuel oil surface, buoyancy suffered by floating drum 20
Reduce, floating drum 20 declines, and when floating drum 20 is separated with sealing cup 15, remaining fuel oil passes through lower exhaust in second channel 121
Mouth 123 flows into fuel tanks.
As shown in figure 8, in second channel 122 and there is no Residual oils in shell 1 under end-state.
The venting communication that the automatic exhaust steam valve and fuel tank aerating system of the application can be used between different fuel tanks, for full
Ventilation requirement when sufficient fuel tank oiling, oil pumping and helicopter flight attitude change, and with small in size, structure is simple, can
The advantages that high, dismounting is easy to maintain by property.
The above, the only specific embodiment of the application, but the protection scope of the application is not limited thereto, it is any
Within the technical scope of the present application, any changes or substitutions that can be easily thought of by those familiar with the art, all answers
Cover within the scope of protection of this application.Therefore, the protection scope of the application should be with the scope of protection of the claims
It is quasi-.
