Fireproof door plate with cooling and heat-insulating functions

Abstract

The invention discloses a fireproof door plate with cooling and heat insulation functions, comprising a plate body, wherein a storage frame made of metal is embedded in the plate body. A piston blockis hermetically and slidably mounted in the storage frame and divides the storage frame into a first cavity and a second cavity; the first cavity is positioned above the second cavity; the first cavity is filled with cooling liquid; evaporation liquid is contained in the second cavity. The evaporation liquid is liquid with a low boiling point, water spraying mechanisms are installed on the two sides of the upper end of the plate body, each water spraying mechanism comprises an atomizing nozzle and a sealing rod, the atomizing nozzles are fixedly installed on the side wall of the plate body, water outlet holes are formed in the plate body, and the atomizing nozzles communicate with the first cavity through the water outlet holes. According to the fireproof door plate, when a fire occurs, the door plate is heated, the temperature rises, cooling liquid is sprayed out of the atomizing spray heads through the water outlet holes, a certain cooling and fire extinguishing effect is achieved after the cooling liquid is sprayed out, and at least the fire spreading speed can be reduced.

Description

technical field [0001] The invention belongs to the technical field of fire doors, in particular to a fire door panel with the function of cooling and heat insulation. Background technique [0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke. It can prevent the spread of fire within a certain period of time and ensure the evacuation of people. [0003] During the fire prevention process of fire doors, the temperature of the door will rise rapidly, it is inconvenient to take measures against the fire or fire doors, and it is easy to cause burns to people; in the prior art, in order to cool the fire doors in time, generally Set up a sprinkler system at the place, and control the opening and closing of the sprinkler system through temperature sensors ...

AI Technical Summary

Problems solved by technology

[0003] During the fire prevention process of fire doors, the temperature of the door will rise rapidly, it is inconvenient to take measures against the fire or fire doors, and it is easy to cause burns to people; in the prior art, in order to cool the fire doors in time, generally Set up a sprinkler system at the place, and control the opening and closing of the sprinkler system through temperature sensors and other components

However, when a fire occurs, due to high temperature or rapid fire spread, the circuit system is easily damaged, which leads to the failure of the sprinkler system to operate normally, and there are certain limitations in use.
