Description
Technical field
The present invention relates to the special repair technology field of aerial extinguishing bottle, specifically a kind of aerial extinguishing bottle
Special repair method.
Background technology
Certain type fire-suppression bottle be used to reviving series, destroy -11 aircraft fire protection systems, per airplane 1, by gas cylinder, adapter coupling, boat
The compositions such as hollow pressure gauge, blast cap, inflation nut.Bottle maximum working pressure (MWP) is not more than 14.7MPa.Fill domestic 1301 fire extinguishing
Aircraft engine nacelle is arranged on after agent, when high temperature (condition of a fire) occurs in enging cabin, the signal of sensor impression is defeated by amplifying
Cockpit fire extinguishing control panel left and right signal lamp is sent to, pilot ignites according to fire condition fires cartridge case on fire-suppression bottle blast cap
Afterwards, extinguishing chemical is ejected into enging cabin on fire by fire extinguishing tube and put out a fire.Because existing for a long time inside fire-suppression bottle adapter coupling
Corrosivity crackle or adapter coupling are produced under the corrosion of extinguishing chemical with bottle because being glued the long failure gas leakage of the time limit, causes to put out a fire
Bottle is not utilized to guideline lives and just scraps or disable, and new fire-suppression bottle price is higher, and procurement cycle is grown, if will can have
The fire-suppression bottle reparation of failure, can either solve the problems, such as to influence production delivery, there is suitable economic value again.
The content of the invention
The technical problems to be solved by the invention are that aircraft fire-suppression bottle adapter coupling produces in the presence of extinguishing chemical
The repair issues that raw corrosion or corrosion cracking, adapter coupling and bottle disable because being glued the long failure gas leakage of the time limit, propose one
The special repair method of kind aerial extinguishing bottle.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of special repair method of aerial extinguishing bottle, comprises the following steps：

Ketone clean twice, dry in atmosphere 5~15 minutes it is stand-by, part glue joint position is applied into one layer of uniform epoxy in one direction
Glue, then it is glued；
S4) assembling test and experiment is parked：The fire-suppression bottle that assembling finishes is connected with testing stand and is put into the airtight examination of gas cylinder
Test in explosion-proof tank and fix, be filled with from filling jointAir pressure, keep 5min, do not allow to leak at each sealing
Gas, when finding gas leakage, it is allowed to be depressurized to 12MPa and search Gas leak position, air seal test heel row is deflated and is depressed intoTwist
Tight inflation nut, disconnects the connection of fire-suppression bottle and pressure system, 2min is kept in potassium dichromate aqueous solution, is not allowed from filling
There is bubble effusion in joint pressure inlet, if bubble escapes, inflation nut should be changed and re-start experiment.
S5 1301 extinguishing chemicals) are filled：Filling joint is loaded onto, certain type fire-suppression bottle is connected and put with extinguishing chemical filling experiment platform
Put the degree of being evacuated on electronic scale and be not more than 103Pa negative pressure states, slowly open and switch is filled on testing stand, make extinguishing chemical slow
Trickle charge enters in fire-suppression bottle, now checks the change of electronic scale numerical value, and 1301 extinguishing chemical weight being finally filled with are 7.4kg, it is allowed to
Deviation ± 3%；
S6) certain type fire-suppression bottle is parked：Qualified fire-suppression bottle will be filled to place at normal temperatures 6~8 days, check fire-suppression bottle weight
Amount loss should be no more than 20g, and fire extinguishing pressure in the bottle highest allows to reduce 0.49MPa than setting, should be by fire-suppression bottle during placement
Vertical fixed, blast cap plugs safety plug.
The step S2) compound method be：Each component successively is weighed in clean with when sequence number by the component with balance
In net container, stirred with clean glass bar and can be used, especially, each dosage does not allow more than 150 grams.
The beneficial effects of the invention are as follows solve aircraft fire-suppression bottle taper thread adapter coupling not decomposing all the time
The problem repaired is realized, adapter coupling is eliminated and produces corrosion or corrosion cracking, adapter coupling in the presence of extinguishing chemical for a long time
With bottle because being glued the long failure gas leakage hidden danger of the time limit, entire life is set to extend to 30000h/30 from 30000h/25, there is provided
Reliable guarantee, the reparation approach that aircraft fire-suppression bottle disables by adapter coupling corrosion and gas leakage is got through.
