Description
Technical field
The invention belongs to fire fighting device technical field, and in particular to a kind of fine spray extinguisher of piston driving.
Background technology
With the development of manned space flight airship, goddess in the moon's series of satellites, China's aerospace industry enters a New Times.These
Certain combustible in space craft cabin be present, once fire occurs, the lighter can cause equipment to be damaged, and severe one may bring calamity
The loss of difficulty（The earth, casualties or aircraft blast can not such as be returned）.Therefore there is an urgent need to a kind of clean and effective
Extinguishing device.Currently, the extinguishing chemical such as foam, dry powder may have certain corrosiveness, extinction using gas to aircraft below deck equipment
Agent（Such as 1301, heptafluoro-propane）Poisonous, it is cold short to be easily caused equipment, pollutes gas in space capsule.Carbon dioxide extinguisher can not
Fast cooling, water or mist fire-fighting may cause space capsule electrical equipment short-circuit.Water mists particle diameter is small, nontoxic corrosion-free,
And to electrical equipment it is harmless or infringement it is smaller.Therefore, one kind that it can put out a fire as space capsule has efficient fire-extinguishing chemical.It is big in standard
Under air pressure, existing fine water mist fire-extinguishing system directly uses gases at high pressure（Such as nitrogen）The water in water pot is driven, by water mists
Shower nozzle sprays.Because space capsule is under microgravity environment, water and gases at high pressure can be mixed, i.e., a large amount of gases, water are mixed in water
Sprayed simultaneously from shower nozzle with gases at high pressure, producing bubble causes that water mists injection is discontinuous, range is short, hence it is evident that influences fire extinguishing effect
Fruit.Therefore, there is an urgent need to a kind of dependable performance, the fine spray extinguisher of clean and effective in aircraft cabin.
The content of the invention
It can be mixed to solve fire extinguishing and existing water mists device water and gases at high pressure under microgravity environment in aircraft cabin
The problem of, while gases at high pressure are made full use of, it is an object of the present invention to provide a kind of water mists of the special piston driving of space capsule
Extinguishing device.
To achieve these goals, the present invention adopts the following technical scheme that：
A kind of fine spray extinguisher of piston driving, including gas cylinder, storage tank, shower nozzle, attached tank flexible pipe, flexible pipe, its feature
It is：Described storage tank, its top are provided with safety valve, pressurized gas inlet, triple valve and reel support；Its outside is provided with flexible pipe
Fixed support；Its bottom is provided with base bearing piece, enters adjutage, enters discharge tube valve and delivery port；Inside is provided with upper limit position block, work

Pressure valve, air valve is provided with storage tank top；The tank top is provided with reel, and one end of flexible pipe is connected on the triple valve of storage tank
Mouthful, the other end of flexible pipe is connected to shower nozzle by nozzle handle, and nozzle handle is provided with nozzle handle valve, and flexible pipe is coiled in reel
On；The cylindrical of the piston is provided with sealing ring, and piston and sealing ring move up and down in reservoir walls, pass through upper limit position block and lower limit
Position block, which is realized, to be moved up and down spacing, and storage tank inner chamber is divided into upper and lower two parts by piston, i.e. top is gases at high pressure, and bottom is water
Body；The right mouth of the triple valve is connected by flexible pipe with the delivery port of storage tank bottom, and lower mouth is connected with the gas outlet on storage tank top；
By threeway Vavle switching, first implement right mouth connection, spray fine mist fire-fighting, then switch lower mouth connection, injection gases at high pressure go out
Fire.
The features of the present invention also resides in：
Described gases at high pressure select nitrogen or carbon dioxide.
Advantages of the present invention and beneficial effect：
1st, the present invention is compact-sized, facilitates in space capsule and quickly moves, and for putting out initial stage and larger fire in time, avoids making a gift of
Opportunity of combat causes fire further to expand by mistake；
2nd, storage tank inner chamber is divided into upper and lower two parts by the present invention using piston, using drive of high-pressure gas piston, first sprays thin water
Mist fill-before-fire gases at high pressure are put out a fire, and effectively prevent the mixing phenomenon of water and gases at high pressure under space microgravity environment, are avoided thin
Atomized water spray is discontinuous, short-range problem, improves extinguishing effect.
