Abstract

The invention discloses an adjustable fireproof valve which comprises a base, wherein a fireproof valve shell is arranged at the top end of the base, a controller is arranged at the top end of one side of the fireproof valve shell, and a temperature sensor and a smoke sensor located below the temperature sensor are arranged on one side of the inner wall of the fireproof valve shell; a rotating motor is arranged on one side of the fireproof valve shell and located below the controller, an output shaft of the rotating motor is connected to a rotating shaft, a rotating plate is arranged on the rotating shaft in a sleeving manner, a rotating column is arranged on one side of the top end of the rotating plate, first rotating rods are symmetrically arranged in the fireproof valve shell, and first rotating doors, second rotating doors and first rotating gears are arranged on the first rotating rods in a sleeving manner; and the first rotating gears are located between the first rotating doorsand the second rotating doors, and second rotating rods located on one sides of the first rotating rods are symmetrically arranged in the fireproof valve shell. The adjustable fireproof valve has thebeneficial effects that the fireproof valve is further closed, the aperture of the fireproof valve is effectively changed, the aperture of the fireproof valve is conveniently adjusted, and the safetyis greatly improved.

Description

technical field [0001] The invention relates to the technical field of fire dampers, in particular to an adjustable fire damper. Background technique [0002] The fire damper is installed on the air supply and return pipelines of ventilation and air conditioning systems, and is usually open. When the temperature of the gas in the pipeline reaches 70°C during a fire, the fusible piece will fuse, and the valve will automatically close under the force of the torsion spring. A valve that can meet the requirements of fire-resistant stability and fire-resistant integrity within a short period of time, and acts as a smoke and fire barrier. When the valve is closed, the close signal is output. At present, when the fire damper is working, the fire damper only has two processes of opening and closing, and the opening of the fire damper cannot be effectively changed. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents o...
