Abstract

The invention discloses a fireproof door. The fireproof door comprises a door frame and a door leaf arranged in the door frame, wherein the door leaf comprises an inner door sheet, an outer door sheet and a fireproof box filled with liquid fire-proofing agents; the fireproof box is located between the inner door sheet and the outer door sheet and provided with nozzles capable of penetrating through the inner door sheet and the outer door sheet respectively; a spray pipe is connected to each nozzle, and the bottom end of each spray pipe is fixed into the fireproof box; a combustible gas alarm is arranged on the inner door sheet and comprises a circuit box, a hanging frame, a guiding frame and a control circuit, wherein the circuit box is used for containing circuit elements, the hanging frame and the guiding frame are arranged on the circuit box, and the control circuit is arranged in the circuit box; the control circuit comprises a transformer, a relay, a buzzer and a thyristor, wherein the transformer is connected with an alternating current source provided by a mains supply, and the relay, the buzzer and the thyristor are sequentially connected in series between the positive output end and the negative output end of the transformer; a gas sensitive element is arranged at the top end of the circuit box and connected with a control electrode of the thyristor; a water pump is connected to a normally open contact of the relay. The fireproof door can give a warning of fuel gas and has a good fireproof property.

Description

technical field [0001] The invention relates to the security field, and specifically discloses a fireproof door. Background technique [0002] Fire is one of the common disasters that threaten the safety of human life. Fire doors refer to doors with fire-resistant properties, which buy time for people to escape from the fire in the event of a fire, prevent the spread of fire, delay the spread of fire, and be fire-resistant for a certain period of time. Therefore, fire doors play a vital role in the event of a fire, and fire doors are widely used in many fields such as residential houses, ships, buildings, chemicals, and mechanical engineering. Now, the commonly used fire doors are all metal doors. Taking advantage of the high melting point of metals, metals are not easy to burn and melt in a fire, so that they can effectively prevent the spread of fire. However, although metal doors are not easily burned, metal has good thermal conductivity. The high temperature conducted...
