Cloth, and one end of pressurizing unit 20 is nested in the inside of fire-retardant separation layer 17, facilitates fire-retardant separation layer 17 after expanded by heating
Extruding promotion is carried out to pressurizing unit 20, is squeezed to be conducive to 20 pairs of cooling filled layers 8 of pressurizing unit, and then can make
The liquid extinguisher adsorbed in cooling filled layer 8, which is squeezed, to be sprayed；
First plate body 21, vertical bar 22, the second plate body 23 and composition " king " font structure of third plate body 26, and the first plate body 21,
Vertical bar 22, the second plate body 23 and third plate body 26 constitute " king " font structure and are made up of in mounting box 24 reset spring 25
Stretching structure facilitates the first plate body 21, vertical bar 22, the second plate body 23 and third plate body 26 to constitute " king " font structure and passes through again
Position spring 25 carries out stretching motion in mounting box 24, so that convenient squeeze the cooling filled layer 8 of sponge material.
Working principle: according to Fig. 1-7, fireproof door plate 2 is carried out on fireproof door frame 1 by connecting hinge 3 first
Rotary closing, fireproof door plate 2 at this time keep being tightly connected by sealing ring 5 and fireproof door frame 1, and when the fire resistant doorsets are fired
When burning, the fireproof door plate 2 of stainless steel material at this time and the heat-insulation door plate 6 of asbestos material the intensity of a fire can be carried out stopping and
Isolation to a certain extent is carried out to high temperature, and when the fire resistant doorsets are by burning, at this time 9 inside of sealing ring 5 and connection sheet
Expansible graphite material 13 expanded by heating of Expandable strip, thus expansion Expandable strip 13 jacks up outward expand apron 12, from
And to connect between fireproof door frame 1 and fireproof door plate 2 even closer, avoid the gap between fireproof door frame 1 and fireproof door plate 2
It is excessive that smoke spillage is caused to cause damages related personnel, and the same of expansion apron 12 is jacked up outward in the Expandable strip of expansion 13
When, expansion apron 12 keeps connection with connection sheet 9 always by link block 11 and link slot 10, improves expansion apron 12 and carries out
The stability of installation；
According to Fig. 1-7, and while thermal-flame burns to the fire resistant doorsets, the fireproof door plate 2 of stainless steel material
Can prevent the fire resistant doorsets from burning the case where penetrating occur, and when temperature is excessively high fireproof door plate 2 and heat-insulation door plate 6 are burnt when,
The fire-retardant separation layer 17 of expansible graphite material is influenced to start to expand by high temperature at this time, thus 17 pairs of extruding dresses of fire-retardant separation layer
It sets 20 to cause to squeeze, so that the fire-retardant separation layer 17 of expansion pushes the first plate body 21, thus by the first plate pushed
Body 21 pushes vertical bar 22 to be slided by the second plate body 23 in the inside of mounting box 24, and vertical bar 22 at this time then pushes third plate
Body 26 is pushed to the inside of fireproof door frame skeleton 7, fire prevention main support body 14 and secondary support body 15 of preventing fires respectively, to fire resistant doorsets
The third plate body 26 that the inside of frame skeleton 7, fire prevention main support body 14 and secondary support body 15 of preventing fires is pushed starts to fire resistant doorsets
The cooling filled layer 8 of sponge material inside frame skeleton 7, fire prevention main support body 14 and secondary support body 15 of preventing fires is squeezed, from
And the liquid extinguishing chemical in the cooling filled layer 8 being extruded begins through sprinkling mouth 18 and passes through the closing ejection of valve 19, thus
External flame is put out, the fire retardant performance of the fire resistant doorsets is improved；
According to Fig. 1-7, fireproof door frame skeleton 7, fire prevention main support body 14 and fire prevention secondary support body 15 are stainless steel material,
The high-temperature resistance of the fire resistant doorsets is improved, while can prevent the fire resistant doorsets from moderate finite deformation occur, and fireproof door frame skeleton 7,
Prevent fires main support body 14 and prevent fires secondary support body 15 inside moisture state cooling filled layer 8 can to fireproof door frame skeleton 7,
Fire prevention main support body 14 and secondary support body 15 of preventing fires carry out cooling to a certain extent, improve fireproof door frame skeleton 7, main branch of preventing fires
The high-temperature resistance of frame body 14 and fire prevention secondary support body 15, while the cooling filled layer 8 of sponge material can also be in pressurizing unit
Liquid extinguishing chemical is squeezed out under 20 extruding to weaken the intensity of a fire, extends escape time for related personnel.
