Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of small non-stored-pressure type extinguishing device in space as shown in the figure, including tank body 7, upper end cover 3, under
End cap 4 and piston 9, it is characterised in that: 7 threaded one end of tank body is connected with upper end cover 3, and the other end is threaded with down
End cap 4, described 3 inside one end of upper end cover are provided with connector 1, and the 1 output end welding gas generator 5 of connector is described
4 threaded one end of lower cover connects lower end joint assembly 2, and described 2 one end of lower end joint assembly is provided with barrier piece 6, the tank body 7
Inside is equipped with piston 9, is threadedly coupled valve inside 10 in the middle part of 9 side of piston, it is close that 9 outer surface of piston is equipped with first
Seal 13,13 side of the first sealing ring are provided with the second sealing ring 12.
Further, in the above-mentioned technical solutions, the valve end of the valve inside 10 protrudes from 9 end face of piston, the gas
Door core 10 is normally off, the piston 9 and the cavity of 3 inner surface of upper end cover and 9 lower surface of piston and it is described under
Completely cut off completely between the inner surface cavity of end cap 4, it is not connected；
