Abstract

The invention relates to a fireproof door with an automatic ventilation function. The fireproof door is characterized in that a louver is formed in a door body, a temperature sensor is arranged on the inner side of the door body, an automatic fireproof shutter unit located above the louver is arranged in the door body, the lower edge of the louver is provided with a seat plate located right below the automatic fireproof shutter unit, a gravity sensor is arranged on the seat plate, the automatic fireproof shutter unit comprises a rolling shaft, rolling ropes wind the rolling shaft, a steel fireproof shutter is fixedly connected to the lower ends of the rolling ropes, a motor is arranged at the end of the rolling shaft and connected with a controller, and a pressure sensor is fixed around the middle section of the rolling shaft. The fireproof door has the advantages that when the steel fireproof shutter is located on the seat plate, the steel fireproof shutter completely covers the louver; due to the fact that the louver is formed in the fireproof door and provided with the automatic fireproof shutter unit and the controller is matched with the temperature sensor on the door body, the pressure sensor on the rolling shaft and the gravity sensor on the seat plate and in linkage with the automatic fireproof shutter unit, and automatic ventilation of the fireproof door and automatic fire and smoke prevention during a fire are achieved.

Description

technical field [0001] The invention relates to a fire door, in particular to an automatic ventilating fire door. Background technique [0002] A fire door is a door used to maintain the fire-resistant integrity of a fire escape and provide a means of escape. Its purpose is to have fire resistance within a certain period of time (usually the escape time), to maintain the integrity and stability of the door, and to have a heat insulation effect. It is the most common fire-resistant partition component in various buildings. Fire doors that meet the requirements should have good performance of high temperature resistance, heat insulation and smoke penetration, and should have the function of self-closing after people pass through in case of fire. At present, there are mainly fire doors with different materials such as steel heat insulation fire doors and wooden fire doors. However, the traditional fire doors only have the function of fire prevention, and do not have the funct...
