Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of gas generator, comprise the gas generator shell, be provided with the gas generator inner casing in the described gas generator shell, described gas generator shell upper port place is provided with igniter base, described igniter base center has pore, link to each other with external igniters by the control cables line in the described pore, it is characterized in that: be placed with the cryogenic gas propellant in the described gas generator inner casing, described cryogenic gas propellant is connected with igniter, described gas generator inner casing outlet side is connected with one-level gross porosity cooling filter, described gas generator outer casing bottom is provided with cooling aerogenesis sustained release agent, described cooling aerogenesis sustained release agent top is provided with secondary cooling filter screen, described gas generator shell and gas generator inner casing directly are provided with three grades of pore cooling filters, and described gas generator shell bottom is provided with the gas outlet.
Described igniter base is the round platform scalariform, and described igniter base center internal thread links to each other with the outer silk in igniter bottom.
Described gas generator shell is the pressure vessel semi-finished product, is welded by cylinder and hemisphere, links to each other by the outer silk of internal thread and igniter base.
Described gas generator inner casing is cylindric, and silk links to each other with one-level gross porosity cooling filter internal thread outside the described gas generator inner casing outlet side.
Described cryogenic gas propellant is cylindric, is positioned in the gas generator inner casing, joins with igniter.
Described one-level gross porosity cooling filter emits the taper perforate that evenly distributes of shape steel part, top disc for lid, and the aperture, outlet side is large, and nearly cryogenic gas propellant stomidium footpath is little.
Described secondary cooling filter screen is round pie compacting gross porosity wire, is stuck in the hemisphere diametrical position.
Described cooling aerogenesis sustained release agent is carbonate compacting bulk product, is positioned between secondary cooling filter screen and the hemisphere.
Described three grades of pores cooling filter is the annulus tubular, is suppressed the tiny cooling filter in space that forms by wire.
Described gas outlet is for being uniformly distributed in gas generator shell bottom.
The beneficial effects of the utility model are: the utility model filters by three grades of coolings, Optimal Structure Designing, and the output gas temperature is less than 100 degree; Make gas generator lower the temperature afterwards and make the inner malleation that keeps of gas generator by the release cryogenic gas that continues in work by adding cooling aerogenesis sustained release agent, even in the inner localized hyperthermia that produces of generator, extraneous fuel gas can not enter generator inside yet and cause second-time burning or blast after the gas-forming agent burning.
