The invention discloses a positive-pressure air supply outlet. The positive-pressure air supply outlet comprises a shell, a panel door and an actuator. An air duct is arranged on the rear portion of the shell. A rectangular mounting groove is formed in the front of the shell. The panel door comprises a panel frame, an air exchange window, partition support tubes, an access door, mounting plates and elastic fasteners. The access door is located above the air exchange window and opened downwards. The access door comprises an access door frame, an access door panel and an access door inner vertical frame. The access door is of an integrated structure formed by bending an integral metal plate. A rotary fixing column is arranged at one end of the access door and movably connected with the panel frame. The air exchange window is provided with a louver window. The mounting plates are located in four directions of the panel door, namely the upper portion, the lower portion, the left portion and the right portion. The panel door is detachably connected with the shell through the mounting plates. The elastic fasteners are located on the mounting plate on the upper portion of the panel door and the mounting plate on the lower portion of the panel door. The mounting plates are detachably connected with mounting holes of the mounting groove through the elastic fasteners.
Description
technical field [0001] The invention belongs to the field of ventilation equipment, in particular to a positive pressure air supply port. Background technique [0002] Positive pressure air supply vent is a kind of ventilation equipment that must be installed in urban buildings, usually installed in the front room, elevator front room, shared front room, and stairwell. The working process is that when a fire occurs, the internal electric actuator will open the air outlet, the temperature-sensing smoke sensor or manual fire alarm will be activated, the positive pressure fan on the top of the tower will be automatically activated, and the air supply shaft will be pressurized to supply air. The front room will continuously supply air to the front room through the positive pressure air supply port, so as to maintain the positive pressure in the front room, so as to ensure that the smoke will not spread in this area, and give people room to escape. When the temperature is higher...
