Abstract
The utility model discloses a kind of easy depression generators, belong to aircraft fuel tank ventilation equipment technical field.Horn mouth is provided on the pedestal, the pedestal and horn mouth junction is provided with compressed air cavity, the easy depression generator is inserted into intake interface by air induction hose, to introduce compressed air into compressed air cavity, compressed air is flowed out from jet hole, form jet stream, it generates volume and inhales flowing, under the action of rolling up suction, so that the air around jet hole is constantly sucked away, to make the pressure in fuel tank be down to atmospheric pressure or less, form certain vacuum degree, so that fuel tank inner air and outer air forms convection current, so that it is guaranteed that fuel tank is suitble to personnel's inside processing；Present apparatus structure novel reaches big flow low vacuum effect using multiple jet principle, and operation and maintenance is convenient, and maintenance cost is very low, and not high suitable for vacuum level requirements, the larger occasion of traffic requirement, using effect is good, and economy is higher, easy to operate.
Description
Technical field
The utility model relates to a kind of easy depression generators, belong to aircraft fuel tank ventilation equipment technical field.
Background technique
The usual vacuum degree of traditional negative pressure generator is high, and flow is small, for not needing very condition of high vacuum degree, to traffic requirement phase
Biggish applying working condition is just no longer applicable in.
For example in aircraft fuel tank ventilation equipment using upper, vacuum level requirements are not high, but traffic requirement is larger, fast and easy
Fuel tank inner air and outer air is formed into convection current displacement, so that it is guaranteed that fuel tank is suitble to personnel's inside processing.
Summary of the invention
In view of the above-mentioned problems, the technical problem to be solved by the present invention is to provide a kind of easy depression generators.
The easy depression generator of the utility model, it includes pedestal, compressed air cavity, compressed air air inlet
Mouth, intake interface, air supply hose, jet hole and horn mouth are provided with horn mouth, the pedestal and loudspeaker on the pedestal
Mouth junction is provided with compressed air cavity, and compressed air inlet port is provided on compressed air cavity, and the compression is empty
Gas air inlet is connect by intake interface with air supply hose, is provided between the compressed air cavity and bell-mouthed cavity
Jet hole.
Preferably, the pedestal is fixedly mounted on fuel tank.
Preferably, the bell-mouthed exit is connect with transparent air hose.
Preferably, the air supply hose is connect with air compressor machine.
Compared with prior art, the utility model has the beneficial effects that the easy depression generator is soft by air inlet
Pipe is inserted into intake interface, to introduce compressed air into compressed air cavity, compressed air is flowed out from jet hole, forms jet stream,
It generates volume and inhales flowing, under the action of volume is inhaled, so that the air around jet hole is constantly sucked away, to make the pressure in fuel tank
Power is down to atmospheric pressure hereinafter, forming certain vacuum degree, so that fuel tank inner air and outer air forms convection current, so that it is guaranteed that fuel tank is suitable
Conjunction personnel's inside processing；Present apparatus structure novel reaches big flow low vacuum effect, operation and maintenance using multiple jet principle
It is convenient, and maintenance cost is very low, be suitable for that vacuum level requirements are not high, and the larger occasion of traffic requirement, using effect is good, economy compared with
Height, it is easy to operate.
Detailed description of the invention
Fig. 1 is the overall structure cross-sectional view of the utility model；
Fig. 2 is enlarged structure schematic diagram at A in Fig. 1.
Appended drawing reference: pedestal 1, compressed air cavity 2, compressed air inlet port 3, intake interface 4, air supply hose 5, jet stream
Hole 6, horn mouth 7, fuel tank a.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As Figure 1-Figure 2, present embodiment uses following technical scheme: it includes pedestal 1, compressed air cavity
2, compressed air inlet port 3, intake interface 4, air supply hose 5, jet hole 6 and horn mouth 7 are provided with loudspeaker on the pedestal 1
The exit of mouth 7, the horn mouth 7 is connect with transparent air hose, and the pedestal 1 is fixedly mounted on fuel tank a, described
Pedestal 1 and 7 junction of horn mouth be provided with compressed air cavity 2, and compressed air air inlet is provided on compressed air cavity 2
Mouth 3, the compressed air inlet port 3 are connect by intake interface 4 with air supply hose 5, the air supply hose 5 and air compressor machine
Connection, is provided with jet hole 6 between the compressed air cavity 2 and the cavity of horn mouth 7.
Working principle: in use, first pedestal 1 is affixed on the fuel tank a of aircraft, air supply hose 5 and air compressor machine
Connection, and introduce compressed air into compressed air cavity 2, compressed air is flowed out from jet hole 6, forms jet stream, is generated volume and is inhaled
Flowing, under the action of rolling up suction, so that the air around jet hole 6 is constantly sucked away, so that the pressure in fuel tank a be made to be down to
Atmospheric pressure is hereinafter, form certain vacuum degree, so that fuel tank a inner air and outer air forms convection current.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
