Description
Technical field
Fire-fighting equipment technical field is the utility model is related to, is to be related to a kind of fire-fighting spraying head specifically.
Background technology
Fire-fighting spraying head is used for spraying system of fire fighting, when a fire, after intravitreous medium reaches certain temperature
Can be vitreum rupture, and then fire demand water is spilt by spray head splash box and puts out a fire, fire-fighting spraying head is fire-fighting system
In an indispensable part.However, even if the region such as almost all of office building, warehouse, public place is both provided with present
Perfect spraying system of fire fighting, still, the fire behavior of generation is because failing timely to be alleviated, putting out a fire to save life and property and cause what fire behavior was aggravated
Situation happens occasionally, and causes easily to cause great casualties and property loss.
In addition, usually when fire behavior comes suddenly, person in distress or manager are except and alarm and can remind personnel fast
Speed withdraw it is outer, to the processing mode of initial fire behavior all the time there are larger passive, so as to cause fire behavior can not be in first time
To alleviating, put out a fire to save life and property.Because when fire behavior happens suddenly and can not artificially be puted out a fire to save life and property, the intensity of a fire can be spread rapidly, also, general fire
Point temperature can be up to 1000 DEG C or so, and the temperature near fire point can also reach several Baidu.At this time, can be to the intensity of a fire of large area
The only fire-fighting spraying head for being put out or being alleviated.But fire-fighting spraying head has certain start-up temperature, also, general
Fire-fighting spraying head can be set aloft as far as possible, enable to have larger swept area, and this frequently can lead to work as
When fire-fighting spraying head reaches start-up temperature and starts, the flame temperature near it has maintained a very high state, and this
When flame caused by hyperthermia radiation have been able to by the object outside several meters it is vehement so so that the startup of fire-fighting spraying head is unable to catch up with
, there is larger the condition of a disaster so as to be easy to cause in the sprawling of the intensity of a fire.As it can be seen that the passivity that existing fire-fighting spraying head starts is larger,
Lead to not in time alleviate fire behavior, put out.
