Abstract
The utility model discloses a fixed fire-extinguishing bottle for aircraft, which belongs to the manufacture field of aircraft fire-extinguishing equipment. The structure design of the fixed fire-extinguishing bottle for aircraft is that the inner liner of a bottle body mainly solves seepage; the outer layer of the bottle body mainly bears explosive force. The fixed fire-extinguishing bottle for aircraft has the advantages of light body and large bearing explosive pressure. The opening of a shutter in a bottle valve can be ensured effectively and reliably through the redesign of the opening angle tolerance of the bottle valve and the tolerance matching of the bottle valve. The fixed fire-extinguishing bottle for aircraft can avoid the phenomenon existing in the prior art that the shutter in the bottle valve can not be opened.
Description
The utility model belongs to the aviation fire-fighting equipment and makes the field.
Prior art in the utility model prior art field is: figure made in CCCP--154 aerial extinguishing bottles, and this fire-suppression bottle is a liner pressure-bearing type structure in bottle design, so body weight, to bear burst pressure low; The opening angle tolerance of bottle valve (blast cap) and the design of bottle valve tolerance fit exist the phenomenon that the bottle valve valve is not opened.
Purpose of design of the present utility model is: avoid weak point of the prior art, design a kind of bottle liner based on the skin that solves seepage, bottle to bear the bottle that force of explosion and body are light, pressure-bearing is high; By redesign, guarantee reliably opening of valve in the bottle valve to the tolerance fit of the opening angle tolerance of bottle valve (blast cap) and bottle valve.
Design of the present utility model:
1, design philosophy: the fixed fire-suppression bottle of aircraft, it comprises bottle, adapter, bottle valve (blast cap) and Pressure gauge, bottle requirement aboard: the one, have reliable mechanical strength, the 2nd, in light weight.The utility model adopts composite, promptly be made into netted skin and constitute bottle by steel liner and high-strength glass fibre, the steel liner solves leakage problems, the purpose that high burst pressure is born in the skin realization that high-strength glass fibre reinforced plastics (fiberglass) twines.Bottle valve (blast cap), it must have certain intensity, structural design is wanted rationally, necessary 100% ground reliability, most important to guaranteeing that effective control function is carried out in sealing, its unlatching is realized by two photophores disposed thereon, valve (valve assembly) is the heart of bottle valve, and the cooperation that therefore reasonably designs bottle valve opening angle tolerance and bottle valve tolerance is the key point that guarantees that valve is reliably opened effectively, and the utility model combines in this point just and designs.
2, organization plan: the fixed fire-suppression bottle of aircraft, it comprises bottle 1, adapter 2, bottle valve 3 and Pressure gauge 4, it is characterized in that: described bottle 1 is that fiberglass outer 22 that the 08AL liner of 1.0mm～1.5mm or titanium liner 21 that thickness is 0.6mm～1.5mm and thickness are 4mm～6mm twines and is composited by thickness.Liner is used to solve leakage problems, and it bears pressure and is about about 1% of burst pressure, and is outer for burst pressure holds the receptor, greater than 58.0MPa.Support set 12 in the bottle valve 3 is φ 22H8/F7 with the tolerance fit of sleeve pipe 14
+ 0.33 0/
-0.020 -0.041Mm, support set 12 are φ 27H9/F7 with the tolerance fit of restraint lid 17
+ 0.052 0/
-0.020 -0.041Mm, support set 12 are φ 22H9/F7 with the tolerance fit of valve body 8
+ 0.052 0/

+ 0.036 0/
-0.013 -0.049Mm, folder spring 16 is 45 ° ± 1 ° with the opening angle tolerance of valve 19 in the bottle valve 3.The appropriate design of bottle valve tolerance fit and bottle valve opening angle tolerance has guaranteed that valve (valve assembly) reliably opens effectively.
3, operation principle: when the aircraft breaking out of fire, send electric signal to the igniter of bottle valve (blast cap), connect electric signal, connect power supply by the autoalarm on the machine or by bridge.After lighting cartridge case igniting blast, because the effect of powder gases, come the spring latch fitting released in the blast cap, under the pressure effect of valve bar in bottle by jack-up, valve bar in the blast cap moves up simultaneously and can make valve body cover the mobile 12～15mm of end at restraint, the position that fire-suppression bottle is in open, at this moment, exit passageway is opened, after extinguishing chemical just sprays in bottle, pressure in the bottle descends, and valve covers jet being sitting in again under the effect of spring on the saddle type seat.So just stoped the extinguishing chemical of spout to flow backwards again to make the return trip empty in the bottle.
The utility model compared with prior art, the one, adopt the bottle liner to solve the outer structure of holding high burst pressure of realizing of seepage, bottle, have simple, body is light, bear big, the advantage reliably of pressure; The 2nd, reasonably design the opening angle tolerance of bottle valve and the tolerance fit of bottle valve, effectively guaranteed opening of bottle valve valve reliably, realized purpose of design of the present utility model.
