Description
Technical field
The utility model belongs to fire-fighting equipment technical field, and in particular to a kind of explosion suppression device -- explosion suppressor.
Background technique
Common storage hanged extinguishing equipment can manually boot or heat-sensitive line detection fire behavior starts extinguishing device automatically.It is existing
Common storage hanged extinguishing equipment referring to attached drawing 1, mainly include shell C, shell C be equipped with driving gas generator A and
Ultra-fine dry powder B is filled in spout D, shell C.
When fire behavior occurs, external alert system discovery fire behavior simultaneously issues alarm, and starting driving gas generator generates gas
Body, device for opening nozzle rupture disk, push ultra-fine dry powder and fire point put out rapidly open fire prevent fire behavior sprawling and
Expansion, avoids bigger loss.
Explosion suppressor, which sprays dry powder doses, puts out the flame during burning or detonation propagation, and burning or explosive flame is inhibited to pass
It broadcasts.Explosion suppression device design and detection establishing criteria: AQ1079-2009 gas tube conveys automatic powder spraying explosion-suppressing device general technology
Condition: it is required that explosion suppressor, which sprays lag time, is not more than 15ms；80% should be not less than by spraying efficiency；Spraying the deadline should be little
In 150ms.And existing common suspension extinguishing device, reaction time are long, spraying efficiency is greater than 95%, sprays the deadline 2 to 3
Second, it is not able to satisfy above-mentioned technical requirements.
Summary of the invention
The purpose of this utility model is in view of the above-mentioned problems, and a kind of novel explosion suppression device of proposition.Explosion suppressor is according to common
The principle of hanged extinguishing equipment and gas generator for safety air sac of storing in a warehouse is prototype, and structure is carried out to it and is redesigned and excellent
Change.
The main technical schemes of the utility model: explosion suppressor, it is characterised in that it includes cylinder assembly, built in cylinder assembly
Fire extinguishing pulvis, cylinder assembly one end are equipped with head assembly of dusting, and the other end is equipped with rear end cap assemblies, rear defence protecting cover and bolt, rear defence
Protecting cover is equipped with buffer, and buffer is equipped with gas vent；It produces pneumatic module and cylinder is fixed on by rear defence protecting cover and bolt seal
It is protruded into cylinder assembly on component and by buffer；Squib is fixed on the cap assemblies of rear end and protrudes into and produces in pneumatic module.
Preferably, the bolt and cylinder assembly are sealed by "O"-ring.
The head assembly of dusting passes through "O"-ring with cylinder assembly and seals.
The rear defence protecting cover and production pneumatic module pass through "O"-ring and seal.
The squib uses AQ-3 type squib.
The utility model further includes the components such as Cross Recess Head Screw commonly used by the field, screw bolt.
The utility model explosion suppressor combines the characteristics of air-cushion inflator and hanged extinguishing equipment, uses peace
Production gas part of the enlarged version of full air bag gas generator as explosion suppressor, the spraying lag time for meeting explosion suppressor requirement are little
In 15ms, technical requirements of the deadline no more than 150ms are sprayed.It is put out using the dry powder of extinguishing device in burning and explosion
Flame, with reach inhibit burning or explosive flame propagation.
