Abstract

The invention discloses an ultra-thin positive pressure blowing valve structure which comprises a valve outer frame, a panel, a middle partition plate, an electric executing mechanism, a blade assembly, a connecting seat, a connecting bend handle, a transmission connecting rod, an opening spring and a closing spring. The panel is fixedly connected to the outer side of an upper mounting port of thevalve body outer frame, the electric executing mechanism is fixedly connected to the back side of the panel, two ends of the blade assembly are movably connected to a lower mounting port of the valvebody outer frame through a rotating shaft, the connecting seat is fixedly connected to the side surface of the blade assembly, a square block at the front end of the connecting bend handle is fixed in the connecting seat, the back end of the connecting bend handle is movably connected to the transmission connecting rod through a hinge pin, the upper end of the closing spring is connected to an action end of the electric executing mechanism and the lower end of the closing spring is connected to the top end of the transmission connecting rod, and the upper end of the opening spring is connected to the tail end of the transmission connecting rod and the lower end of the opening spring is connected to the bottom of the valve body outer frame. The ultra-thin positive pressure blowing valve structure has the advantages of being simple in structure, high in safety, capable of reducing size of equipment and the like.

Description

technical field [0001] The invention relates to the technical field of fire protection equipment, in particular to an ultra-thin positive pressure air supply valve structure. Background technique [0002] The positive pressure air supply valve is usually installed on the wall of the positive pressure air supply shaft in the front room of the elevator in residential buildings, office buildings, and commercial buildings. Normally closed state; when a fire breaks out on a floor, the positive pressure air supply valve transmits the smoke signal in the front room of the elevator to the fire control room, and through the automatic system of the fire control room, the positive pressure air supply valve is given a 24V power supply to start the fire floor and up and down The air valve on the adjacent floor and the positive pressure blower are activated at the same time, and the positive pressure blower introduces outdoor fresh air to blow away the smoke from the fire floor and the st...
