Technical Field
[0001] The utility model relates to the technical field of smoke exhaust valves, in particular to a remotely controlled smoke exhaust valve. Background Technique
[0002] A smoke exhaust valve is a fire-fighting component, generally installed on the pipeline of a mechanical smoke exhaust system, usually in an open state, opens for smoke exhaust during a fire, closes when the smoke temperature in the smoke exhaust pipeline reaches 280 degrees, and meets the requirements of smoke leakage and fire resistance integrity within a certain time, playing a role in isolating smoke and fire.
[0003] At present, the smoke exhaust fire valves produced on the market will expand due to heat, thus squeezing the outer frame, resulting in the deformation of the blade due to extrusion, unable to play the role of sealing smoke and open fire, resulting in poor airtight performance after expansion of the smoke exhaust fire valve, and there are still gaps between the upper and lower ends of the blade shaft and the corresponding partition plates even when the blade shaft is closed at present, and air can still enter the ventilation pipeline, so the smoke isolation effect of most smoke exhaust valves is not good. Content of the Utility Model
[0004] To solve the above problems, that is, to solve the problems raised in the above background technique, the utility model proposes a remotely controlled smoke exhaust valve, which includes a valve body, a group of partition plates, a remote control receiver, a temperature sensor and a control box. A group of partition plates are installed in the valve body. An installation cavity is formed between the partition plate on the uppermost side and the valve body. The remaining partition plates divide the valve body into a group of ventilation cavities. The remote control receiver and the control box are both arranged on one of the partition plates in the upper part. The temperature sensor is installed on one side in the valve body, and a blade adjusting mechanism is installed in the valve body.

Detailed Embodiments
[0018] The following describes the preferred embodiments of the present utility model with reference to the attached Figures 1 - 3 Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.
[0019] The present utility model provides a remotely controlled smoke exhaust valve. When using this device, the valve body 1 is installed on the ventilation duct through a set of mounting holes 6. In the normal state, a set of blade shafts 5 are in the open state. In case of a fire, the temperature sensor 10 senses the temperature and feeds it back to the remote control receiver 3. The remote control receiver 3 transmits the signal to the control box 7. The control box 7 starts to control the electric push rod 12 to start. The output end of the electric push rod 12 extends to drive the connecting rod 8 to slide. The connecting rod 8 drives a set of swing rods 9 to swing. With the cooperation of the swing rod 9 and the connecting rod 8, the electric push rod 12 swings. A set of swing rods 9 drive the corresponding blade shafts 5 to swing. The larger the swing angle of a set of blade shafts 5, the larger the gap of a set of ventilation cavities 14, the better the smoke exhaust effect, and the smoother the smoke exhaust. When the blade shaft 5 swings to the maximum angle, the electric push rod 12 stops operating, and this device conducts the smoke exhaust work. When the temperature sensor 10 detects that the flue gas temperature in the smoke exhaust duct reaches 280 degrees, the electric push rod 12 starts again. The output end of the electric push rod 12 retracts to drive a set of blade shafts 5 to swing in the opposite direction. When the output end of the electric push rod 12 is fully retracted, the electric push rod 12 stops operating. At this time, the upper protrusions on each blade shaft 5 are respectively in close contact with the corresponding upper clamping strips 11, and the lower protrusions on each blade shaft 5 are respectively in close contact with the corresponding lower clamping strips 13, achieving the purpose of good sealing. At this time, a set of blade shafts 5 cooperate with the corresponding upper clamping strips 11 and lower clamping strips 13 to form a closed wall to block the smoke from exhausting, achieving the purpose of smoke isolation and fire prevention. By controlling the opening and closing of the blade shaft 5 through the cooperation among the temperature sensor 10, the remote control receiver 3, and the control box 7, the smoke exhaust and smoke isolation of this device are controlled, enabling better fire protection operations.
