Abstract
The invention discloses a non-stored-pressure type piston pressurizing automatic fire extinguisher. The non-stored-pressure type piston pressurizing automatic fire extinguisher comprises a medicament storage cylinder, a piston which is arranged in the medicament storage cylinder, and a gas generating device, wherein the piston divides an inner cavity of the medicament storage cylinder into a completely-closed medicament cavity and a driving cavity; the outer circumference of the piston is in sliding fit with the inner wall of the medicament storage cylinder; the medicament cavity is connected with a spray head through a medicament output port; and the driving cavity is connected with the gas generating device through a vent hole. According to the automatic fire extinguisher, under the action of a high-pressure gas generated by the gas generating device, the piston ejects a fire extinguishing agent in the medicament cavity out through the spray head to perform fire extinguishment, so that many problems of the conventional stored-pressure type fire extinguisher and non-stored-pressure dry powder fire extinguisher are effectively solved. The non-stored-pressure type piston pressurizing automatic fire extinguisher has the advantages of high fire extinguishing efficiency, compact structure, no need of inflation pressurization, complete emptying of the fire extinguishing agent, adoption of various fire extinguishing agents and the like, and has wider application ranges and fields.

Technical field
The invention belongs to the fire prevention field, particularly a kind of non-stored-pressure type piston pressurization automatic fire extinguisher.
Background technology
At present, unless, outside the stored-pressure type dry powder extinguishing installation, most of automatic fire extinguishers are all stored-pressure types, that is: drive the gas (being generally nitrogen) of agent application to be stored in a container with elevated pressures.Because driving gas is long-term with pressure depositing, very easily produce and leak, in the urgent need once the condition of a fire occurs, can occur that because driving pressure is not enough fire-fighting efficiency reduces the phenomenon that maybe can't spurt.Therefore, must regularly carry out pneumatic compression to this class extinguishing device.Because the quantity that the stored-pressure type extinguishing device comes into operation is quite huge, numerous extinguishing device like this is carried out to frequent inflating pressure and become a kind of very numerous superfluous work.
On the other hand, the driving gas of stored-pressure type extinguishing device and extinguishing chemical are stored in same container and pressurization usually jointly, and inevitable some driving gas of this mode can be dissolved in liquid-state extinguishing agent.When extinguishing chemical, in pipeline in course of conveying, along with pressure constantly reduces, driving gas will be accompanied by extinguishing chemical steam and discharge, produce a large amount of gas, carrying, form air bag and two-phase flow phenomenon in pipeline, directly affect the mobile performance of extinguishing chemical, reduced 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, when extinguishing chemical discharges, pressure decreased is more obvious, and the gas discharged is more, and air bag and two-phase flow phenomenon in course of conveying are more serious, have reduced fire-fighting efficiency.
The gas-powered powder extinguishing agent that non-stored-pressure type dry powder extinguishing installation adopts chemical reaction to generate spurts, although solved, do not need to extinguishing device inflating pressure problem, but because using powder extinguishing agent, limited in its scope of application, also having more distinct issues is that the extinguishing chemical rate of residual extinguishing medium is high.
