Problems solved by technology

[0002] Existing fire doors are used to isolate the flames in elevator rooms or corridors in case of fire, prevent the spread of fire and the spread of toxic smoke, and protect people from evacuating and escaping smoothly. They are made of flame-retardant materials and have flame-retardant properties. The performance of automatic fire extinguishing in the event of a fire, so improvement is urgently needed

Embodiment 1

[0019] refer to figure 1 , a new type of fire door, including a door body 1, the door body 1 is provided with a water storage chamber 2 and a metamorphosis chamber in sequence from top to bottom, and a partition plate 3 is fixedly connected horizontally and airtightly in the metamorphosis chamber, and the partition board 3 separates the metamorphosis chamber from the From top to bottom, it is divided into a booster chamber 4 and an evaporation chamber 5. The water storage chamber 2 and the evaporation chamber 5 are filled with water and evaporation liquid respectively. A temperature-sensitive plate 10 is embedded on the outside of the door body 1 and at the corresponding position of the evaporation chamber 5. , the temperature sensing plate 10 is made of heat-conducting material, and the other parts of the door body 1 are made of heat-insulating material, and the middle part of the partition 3 is provided with a one-way air inlet 6 communicating with the booster chamber 4 and t...

Embodiment 2

[0024] refer to figure 2 , the present embodiment makes the following improvements on the basis of embodiment 1: a sentinel pipe 13 is arranged horizontally in the air injection pipe 7 .

[0025] The difference between this embodiment and Embodiment 1 is that when the high-pressure gas passes through the gas injection pipe 7, the whistle pipe 13 will be blown to generate a huge whistle to remind people of the occurrence of fire, fire treatment and timely escape .

Abstract

The invention discloses a novel fire door. The novel fire door comprises a door body, wherein a water storage cavity and a state changing cavity are formed in the door body in sequence from top to bottom; the inside of the state changing cavity is horizontally and fixedly connected with a partition plate in an airtight manner; the partition plate is used for dividing the state changing cavity intoa pressurization cavity and an evaporation cavity from top to bottom; the water storage cavity and the evaporating cavity are respectively filled with water and evaporation liquid; a temperature sensing plate is embedded in a corresponding position of the evaporation cavity on the outer side of the door body; a one-way air inlet hole communicated with the pressurization cavity and the evaporationcavity is formed in the middle part of the partition plate; the top end of the pressurization cavity is communicated with a gas spraying pipe; and a pressure valve is mounted in the gas spraying pipe. The novel fire door has the advantages that the evaporation liquid is vaporized after continuously receiving heat and is sprayed out by the gas spraying pipe after certain pressure is accumulated inthe pressurization cavity, so that the water in a capillary pipe is automatically extruded and torn for carrying out spray extinguishing treatment on the fire on the outer side of the door body and reducing the extension of the fire to a certain extent.

Description

technical field [0001] The invention relates to the technical field of doors, in particular to a novel fire door. Background technique [0002] Existing fire doors are used to isolate the flames in elevator rooms or corridors in case of fire, prevent the spread of fire and the spread of toxic smoke, and protect people from evacuating and escaping smoothly. They are made of flame-retardant materials and have flame-retardant properties. The performance of automatic fire extinguishing in the event of a fire is therefore in dire need of improvement. [0003] In order to solve the above problems, we propose a new type of fire door. Contents of the invention [0004] The purpose of the invention is to solve the problems in the background technology, and propose a novel fire door. [0005] In order to achieve the above object, the present invention adopts the following technical solutions: [0006] A new type of fire door, including a door body. The door body is provided with ...
