Abstract

The utility model relates to a steel fireproof door with double open for places of the department of petroleum, chemical industry, metallurgy, post telephone and telegraph, electric force, etc. to lay down cables densely, and the utility model is especially suitable for fire protection of the cable tunnel of a power plant. The utility model is characterized in that the fireproof door can be automatically closed when the fire accident occurs at either single side of the fireproof door, and as a result, the purpose of fire prevention can be achieved through the retardation of the fire and the isolation of smoke effectively. The utility model has the advantages of simple structure, beautiful appearance, low cost, convenient processing and installation, long service life, and repeatable use after dismounted.

Description

Steel fire door of double open
The utility model relates to a kind of two-sided fire resistance steel door of opening; it has fire prevention and every characteristics such as smoke performance is good, intensity is high, simple in structure, good looking appearance, cheap, easy for installation, long service life, simultaneously to suppressing fire spread and the protection safety evacuation has important role.Can be widely used in the place of the intensive layings of department's cable such as oil, metallurgy, post and telecommunications, electric power, be specially adapted in the cable tunnel of power plant.
In having adopted, fills out the utility model the two-door fan of steel work of high-quality anti-flaming thermal-insulation material, and have automatic closing system, overcome the defective of existing labeled door, no matter which side breaking out of fire of door, labeled door can both be closed automatically, intercepts fire spread and prevents the purpose that accident enlarges thereby reach.
Now further specify by accompanying drawing:
Figure of description one is the structural representation of the present utility model that meltable band is housed.
Figure of description two is structural representations of the present utility model that the tractive magnet that matches with fire detector is housed.
Figure of description three is fire detector electrical systematic drawings.
Two-sided shown in the figure one open fire resistance steel door by door leaf 1, doorframe 2, shelves bar 3, spring hinge 4, spring pressure bar 5, bump pearl 6, anti-flaming thermal-insulation material 7, meltablely be with 8, handle 9, magnet 10 form.Meltable be connected in cable tray over the 5m with 8 along cable louding on, and flexible is freely.In case ignition of cable meltablely is with 8 to disconnect, door leaf 1 cuts out under the effect of spring hinge 4, spring pressure bar 5 automatically, sucks sealing automatically under the synergy of shelves bar 3, magnet 10, thus play back-fire relief every cigarette, prevent the effect of fire spreading.
Two-sided shown in the figure two opens fire resistance steel door and structurally only is that with the difference of figure one the self closing device part is made up of tongue shell 11, tractive magnet 12, dead bolt 13.
14 is that fire detector (temperature-sensitive, sensitization or sense cigarette type) is by being loaded on top board centre position, cable tunnel every four meters one among the figure three.Adopt parallel connection between all probes 14 and the controller 15.Controller 15 is loaded on the tunnel portal place, adopts applied fireproofing as external protection.On tractive magnet 12 is placed in tongue shell 11 on the labeled door matches the tunnel-side or cable tray, so that the dead bolt of tractive magnet 12 13 keeps good fit with tongue shell 11 on the labeled door.When dead bolt 13 At time of ejects, just in time put in the tongue shell 11, keep the normal unlatching of door; When dead bolt 13 is pulled electromagnet 12 and sucks, labeled door will be closed under the effect of spring hinge 4 and spring pressure bar 5 automatically, and suck sealing automatically under the effect of magnet 10 and shelves bar 3, thereby play isolated burning things which may cause a fire disaster, prevent the effect of fire spreading.
When the arbitrary probe in this tunnel 14 fire signs such as smog, flame or high temperature occur in because of the tunnel, signal can take place give controller 15, controller 15 provides driving voltage to tractive magnet 13 with signal amplification, comparison, analysis confirmation during for the fire sign, dead bolt 13 is sucked automatically, labeled door is closed automatically.If with controller 15 and central station of floating dock computer networking, controller 15 can send fire signal to central station of floating dock simultaneously.
Automatic closing system shown in accompanying drawing one and the accompanying drawing two can mix use, if meltable be with 8 and tractive magnet 12 one of them have an effect, labeled door just can be closed automatically, has improved the safety and the reliability of labeled door.
The size of labeled door can determine to make series of products according to construction module and field condition.
