Description
Technical field
The utility model relates to fire distinguisher technical field more particularly to a kind of perfluorethyl isopropyl ketone self-extinguishing systems
System.
Background technique
Currently, most of occasions and equipment are provided with extinguishing device, it is in general only equipped with fire extinguisher, but this side
Formula can only wait discovery after passively put out a fire, cannot accomplish the equipment timely and effectively prevented fires, and had be chronically at closing or
Person's semi-closed state, loss is bigger when often finding.
And in some important and uninhabited region, it is often equipped with fire alarm and automatic fire extinguishing system, but
There is a problem that 1. structure is complicated, the cost of a whole set of equipment is more expensive, and electronics control is more complicated, and single is released
It is also very high to put cost；2. traditional automatic spraying device, room head temperature just starts to react when reaching 68 DEG C, and at this moment fire behavior has been
It is not prompt enough through spreading, and water is not ideal extinguishing chemical, it is big to equipment damage, and fire extinguishing dead angle easy to form；
Fire trace tube automatic fire extinguisher, structure is simple, at low cost, and complete equipment is only by a fire trace tube, air valve, with
And fire-suppression bottle composition；More sensitive to fire behavior, the arrangement of fire trace tube is generally all close to fire source, when fiery source temperature is more than 160 DEG C
When kindling (i.e. just), fire trace tube will melt rapidly, discharge the nitrogen in outlet pipe, and air valve automatically open extinguishing chemical also can be from
It is discharged in bottle, the active quick extinguishing from root；Several extinguishing chemical types --- the CO generallyd use2, dry powder, FM-200 (seven
Fluoro-propane gas extinguishing agent, chemical name are heptafluoro-propane, chemical molecular formula CF3CHFCF3) etc. often put out a fire after have residual,
It causes serious irrecoverability to damage electronic equipment, and pollutes environment, be harmful to the human body.
Utility model content
The purpose of this utility model is to provide perfluorethyl isopropyl ketone automatic fire extinguishing systems, to solve in the prior art
