Description
Technical field
The invention belongs to aircraft fire suppression system technical field, in particular to a kind of fire-suppression bottle lock device.
Background technique
Structure is complicated for traditional fire-suppression bottle lock device, needs multiple components cooperations to work at work, reliably
Property is low；And the work valve in traditional fire-suppression bottle lock device uses end face seal form, and high-pressure extinction agent is easy to cause to let out
The failure of leakage, fire-suppression bottle failure.Present invention optimizes the structure types of fire-suppression bottle lock device, using the mode of " failure by shear "
Extinguishing chemical is connected, improves leakproofness and reliability.
Summary of the invention
(1) goal of the invention: the present invention overcomes deficiency in the prior art, it is simple to provide a kind of structure, leakproofness
Good, high reliablity fire-suppression bottle lock device.
(2) technical solution: in order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions:
A kind of fire-suppression bottle lock device, by filler (1), shell (2), pressure inlet (3), sealing ring (5), detonating primer (6),
Trigger connector (7), insurance film (9), pressure gauge (10) composition.Further include piston (4), siphon pipe (8), the piston (4) and
Siphon pipe (8) is vertically mounted on shell (2) inside, and the cutter on piston (4) is bonded with the end of siphon pipe (8).
Wherein, it is provided with cutter in the middle part of piston (4), which is the key-way shape structure of one end open.It is set in the middle part of piston (4)
It is equipped with annular groove, width is consistent with siphon pipe (8) internal diameter.When lock device detonating primer (6) does not excite, cutter face and siphon pipe
(8) end flushes, and annular groove is not turned on siphon pipe (8)；When lock device detonating primer (6) excite work, cutter cuts off rainbow
The Forward of suction pipe (8) end, annular groove and siphon pipe (8) are connected.
Piston (4) both ends are respectively provided with sealing ring (5) and 11 ° of conical surfaces with annular tooth, in lock device detonating primer (6)
When excitation, sealing ring (5) is isolated by detonating primer (6) combustion gas and residue with extinguishing chemical, prevents the pollution of extinguishing chemical and its pipeline.Together
When, piston (4) moves axially under the action of detonating primer (6) combustion gas, and the conical surface with annular tooth is made to be embedded in lock machine shell (2) bottom
11 ° of conical surfaces in locking, prevent piston (4) rebound block extinguishing chemical access.
Siphon pipe (8) end is designed as the closed integral structure of back taper, and is provided with annular thin wall.It is passed in lock device
When booster (6) does not excite, piston (4) cutter does not work, closed integral type end reliably guarantees that extinguishing chemical does not lose in fire-suppression bottle body
Pressure；When lock device detonating primer (6) excite work, push piston (4) cutting siphon pipe (8) end annular with cutter thin
Wall opens the access of fire-suppression bottle output extinguishing chemical, realizes fire-extinguishing function concurrently.
(3) beneficial effect
Compared with prior art, the invention has the advantages that structure is simple, good airproof performance, high reliablity.
Detailed description of the invention
Fig. 1 is fire-suppression bottle lock device figure of the present invention；
Wherein: 1- filler, 2- shell, 3- pressure inlet, 4- piston, 5- sealing ring, 6- detonating primer, 7- trigger connector, 8-
Siphon pipe, 9- insure film, 10- pressure gauge.
Specific embodiment
1 present invention is further described in detail with specific embodiment with reference to the accompanying drawing:
A kind of fire-suppression bottle lock device, by filler (1), shell (2), pressure inlet (3), sealing ring (5), detonating primer (6),
Trigger connector (7), insurance film (9), pressure gauge (10) composition.Further include piston (4), siphon pipe (8), the piston (4) and
Inside housings, the cutter on piston (4) is bonded siphon pipe (8) right angle setting with the end of siphon pipe (8).Wherein, piston (4)
Middle part is provided with cutter, which is the key-way shape structure of one end open.Annular groove, width are provided in the middle part of the piston (4)
It is consistent with siphon pipe (8) internal diameter.And piston (4) both ends are respectively provided with sealing ring (5) and 11 ° of conical surfaces with annular tooth.It is described
Siphon pipe (8) end is designed as the closed integral structure of back taper, and is provided with annular thin wall.
1, when there is fire behavior, triggering connector (7) receives firing command, detonating primer (6) detonation, and high-pressure gas pushes band to cut
The piston (4) of knife moves axially, and the annular thin wall of cutter cutting siphon pipe (8) end on piston (4) opens fire-suppression bottle output
The access of extinguishing chemical, i.e. extinguishing chemical are flowed to pressure inlet (3), arrived by siphon pipe (8) through the annular groove on the piston (4) with cutter
Up to the place that catches fire, fire-extinguishing function concurrently is realized.
2, piston (4) is being provided with 11 ° of conical surfaces with annular tooth far from propagation of explosion pipe end, when siphon pipe (8) end is cut off
Afterwards, continue to move axially using the remaining kinetic energy of piston (4), be embedded in locking in 11 ° of conical surfaces of lock machine shell (2) bottom, to prevent
Only piston rebound.
3, it is provided with annular groove in the middle part of piston (4), when its axial movement and locking, annular groove and rainbow in the middle part of piston (4)
Suction pipe (8) and pressure inlet (3) guarantee extinguishing chemical pathway patency to just.
4, propagation of explosion tube end is provided with sealing ring (5) on piston (4), can guarantees detonating primer combustion gas and residue and goes out
Fiery agent isolation, prevents the pollution of extinguishing chemical and its pipeline.
5, siphon pipe (8) end use the closed integral structure of back taper, guarantee under normal circumstances extinguishing chemical access can
By blocking, prevent from leaking.
6, siphon pipe (8) end is provided with annular thin wall, can guarantee resolutely to be cut under the active force of piston (4) cutter
It is disconnected.
