Description
Technical field
The present invention relates to the field of structural design technology of aircraft, particularly to the draining of aircraft, tool
Body is the water discharge method of a kind of aircraft air-tight cabin.
Background technology
Airframe is the use space enough to the offer of crew, passenger or goods, aircraft
When routine use, owing to fuselage interior is mounted with a lot of equipment, these equipment operationally can
Produce heat, condensed water will be produced in interior of aircraft when aircraft internal-external temperature difference reaches certain value
And accumulate in interior of aircraft；On the other hand, owing to fuselage seal approach is bad, some movable part
Part, such as, vent window, lid etc. sealing member is aging, will be from these portions when running into rainy
Position rain oozes in the cabin as entered aircraft.These hydrops accumulated in aircraft cabin are necessary
There is measure to ensure to discharge out of my cabin, be therefore necessary for when airframe designs considering drainage problem.
Draining in airframe air-tight cabin in prior art, is to accumulate in fuselage air-tight cabin
The water in portion, stringer breach and stringer vertical edge by bulkhead are madeHole, is drained to
Underbelly lowest part, on the eyelid covering of underbelly lowest part, varying number processed is a diameter of Leaking hole by hydrops discharge, generally airframe be requirement ensure airtight,
And these leaking holes are while draining, also easily cause the gas leakage of fuselage air-tight cabin, thus cause
The pressure release of fuselage main cabin causes danger.
Therefore the water discharging valve of a kind of aircraft air-tight cabin is designed, when fuselage air-tight cabin is in normal pressure shape
During state, by this device, the hydrops in fuselage is discharged；When air-tight cabin is in pressurized state,
This device is automatically switched off to ensure the air-tightness of fuselage air-tight cabin, thus reaches amassing in fuselage
Water is discharged aircraft exterior and is just seemed the most necessary.
Summary of the invention
For the problem overcoming fuselage present in prior art easily to leak gas when draining, this
The bright water discharge method proposing a kind of airframe.
The water discharge method of a kind of aircraft air-tight cabin, it is characterised in that in the bottom of aircraft air-tight cabin
Body is provided with a water discharging valve, and the upper end of this valve body is a start cylinder, body
Lower end in shorten step cylinder into, the barrel of step cylinder is provided with osculum, this osculum and step
Cylinder lower end outlet, has a piston body to be embedded in the start cylinder of body upper end by spring
In, the upper end of this piston body is mated with the inwall of the start cylinder of body, the lower end of piston body and
The step cylinder coupling of body lower end, start cylinder inboard wall is embedded with the spacing back-up ring of piston body,
Another have a longitudinal passage will to connect outward with bottom step cylinder in pressurized strut body on step barrel
Logical, valve body by be fixed in the middle part of valve body on start cylinder body outer wall multiple obliquely
The leg dissipated is fixed on the housing construction of aircraft, and the outlet of valve body lower end step cylinder is led to
The circular hole crossed on body is in communication with the outside.
Aircraft is when atmospheric pressure state, and piston body rises under the action of the spring, amassing of underbelly
Water is flowed into the lower end outlet of valve body lower end step cylinder from osculum, through eyelid covering and reinforcement
On hole flow to external fuselage.When aircraft air-tight cabin is in pressurized state, piston body is at air pressure
Along the inwall slide downward of pressurized strut under effect, the spring outside piston body is compressed, piston
Air between body and start cylinder discharges external fuselage by passage, and piston body lower end will
Osculum blocking on step barrel, to ensure the air-tightness of aircraft air-tight cabin.
The invention have the advantages that
1) simple in construction, can intuitively, quickly, timely by the hydrops of fuselage interior be discharged to machine
Outside body.
2) while solving fuselage hydrops problem, it is ensured that the air-tightness of aircraft.
Below in conjunction with embodiment accompanying drawing, this application is described in further detail:

Detailed description of the invention
Seeing accompanying drawing, the present embodiment is the water discharging valve of a kind of aircraft air-tight cabin, valve body
The upper end of 12 is a start cylinder 6, shortens step cylinder 11, step in the lower end of body 12 into
The barrel of cylinder 11 is provided with osculum 13, and this osculum 13 exports 10 with step cylinder 11 lower end
Connection, has a piston body 4 to be embedded in the start cylinder 6 of body 12 upper end by spring 5
In, the upper end of this piston body 4 is mated with the inwall of the start cylinder 6 of body, piston body 4
Lower end is shunk and is mated with the step cylinder 11 of the lower end of body, separately has one on step barrel wall
Individual longitudinal passage 9 connects with step cylinder 11 outer bottom in start cylinder 6.
In order to alleviate aircraft weight as far as possible, there are lightening hole, piston body in the upper end of piston body 4
The top of 4 is slidably matched with start cylinder 6 inwall, the bottom of piston body 4 and step cylinder 11
Inwall is slidably matched, and spring 5 is arranged on the outer round surface of piston body 4.In order to limit piston
The motion of body 4 is formed, and start cylinder 6 inwall of body upper end is embedded with the limiting block of piston body
Circle 2.The upper surface of body 12 is coated with infantees 1, is wrapped with bundle line 2, is used for protecting
Protect foreign body and enter pressurized strut.
For the ease of install, middle part start cylinder 6 outer wall of body 12 is fixed with multiple tiltedly
The leg 7 dissipated downwards.
Pressurized strut 6 uses the method for welding to be connected with leg 7, leg 7 and airframe 8
Being bolted, body is shaped with circular hole, the outlet at bottom 10 of body lower part step cylinder leads to
The circular hole crossed on body connects with outside atmosphere.
Aircraft is when atmospheric pressure state, and piston body 4 rises under the effect of spring 3, underbelly
Hydrops from osculum 13 be flowed into valve body lower end step cylinder 11 lower end outlet 10,
Circular hole on fuselage discharges engine body exterior.When aircraft air-tight cabin is in pressurized state, piston body
4 under the influence of air pressure along the inwall slide downward of start cylinder 6, the bullet outside piston body 4
Spring 3 is compressed, and the air between piston body 4 and start cylinder 6 is discharged by passage 9
External fuselage, the osculum 9 on step barrel is blocked by piston body 4 lower end, to ensure aircraft
The air-tightness of air-tight cabin.
