Abstract

The invention belongs to the technical field of fire-fighting fireproof equipment, and particularly relates to a cylindrical rotary opening fire-fighting fireproof valve. The valve comprises a valve body, a first supporting rod, a second supporting rod, a first rotary baffle, a second rotary baffle, a third rotary baffle, a sealing limiting plate, a rotary shaft, a motor and a transmission component. The motor drives the rotary shaft to rotate, then the second rotary baffle and the third rotary baffle are driven to rotate, in the process, the rotary shaft drives a first limiting pin to rotate,the first limiting pin drives a second limiting pin to rotate through springs, and the second limiting pin drives the second rotary baffle to rotate. When one side of the third rotary baffle is inserted into a first groove in the sealing limiting plate, the fireproof valve is closed, high-temperature flue gas is prevented from entering a pipeline, the high-temperature flue gas is prevented from entering other rooms through the pipeline, fire disasters in the other rooms are avoided, a fire disaster area is isolated, and fire spreading is avoided; and the losses caused by fire disasters to personal and property safety are further reduced.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting and fire-fighting equipment, in particular to a cylindrical rotary-open fire-fighting and fire-fighting valve. Background technique [0002] Fire damper refers to a movable closing device that can meet the requirements of fire resistance stability and fire resistance integrity within a certain period of time, and is used to block smoke and fire in ventilation and air conditioning ducts. When a fire breaks out in a building with ventilation and air conditioning systems, the vertical and horizontal air ducts passing through floors and walls are the main way for fire to spread. The fire damper is installed on the air supply and return pipes of the ventilation and air conditioning system, and is normally open. When a fire occurs, it will be closed when the gas temperature in the pipe reaches the set temperature. It can meet the requirements of fire resistance stability and fire resistance integr...
