Description
Technical field
The invention belongs to technical field of fire control, particularly one non-stored-pressure type piston pressurization automatic fire extinguisher.
Background technology
At present, unless outside stored-pressure type dry powder extinguishing installation, most of automatic fire extinguisher is all stored-pressure type, that is: drive the gas (being generally nitrogen) of agent application to be stored in a container with elevated pressures.Because driving gas is with pressure for a long time depositing, very easily produce leakage, urgently needed once the generation condition of a fire, can occur that fire-fighting efficiency reduces the phenomenon maybe cannot spurted because driving pressure is not enough.Therefore, regularly must carry out pneumatic compression to this kind of extinguishing device.The quantity come into operation due to stored-pressure type extinguishing device is quite huge, carries out frequent inflating pressure become a kind of very numerous superfluous work to so numerous extinguishing devices.
On the other hand, the driving gas of stored-pressure type extinguishing device and the usual common storage of extinguishing chemical are in same container and pressurize, and this mode some driving gas inevitable can be dissolved in liquid-state extinguishing agent.When extinguishing chemical is in pipeline in course of conveying, along with pressure constantly reduces, driving gas will discharge along with extinguishing chemical steam, produce a large amount of gas, in conveying, in pipeline, form air bag and two-phase flow phenomenon, directly affects the mobile performance of extinguishing chemical, reduce the flow of extinguishing chemical.Extinguishing chemical and driving gas are stored in same container, and the storage volume of driving gas is limited, and storage pressure can not be too high.Because the meltage of the higher driving gas of storage pressure is more, during extinguishing chemical release, pressure reduces more obvious, and the gas discharged is more, the air bag in course of conveying and two-phase flow phenomenon more serious, reduce fire-fighting efficiency.
The gas-powered powder extinguishing agent that non-stored-pressure type dry powder extinguishing installation adopts chemical reaction to generate spurts, do not need to extinguishing device inflating pressure problem although solve, but because can only powder extinguishing agent be used, limited in its scope of application, also there are more distinct issues is that extinguishing chemical rate of residual extinguishing medium is high.
