Embodiment Construction
[0022] The present invention will be further described in detail below with reference to the accompanying drawings.
[0023] Wherein the same parts are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "bottom" and "top" "Face", "inner" and "outer" refer to directions toward or away from the geometric center of a particular part, respectively.
[0024] refer to figure 1 As shown, it is an air leakage control system of a smoke prevention and exhaust system in a preferred embodiment of the present invention, including a control center and a smoke exhaust module, and the smoke exhaust module includes a smoke exhaust pipeline, a flow meter, a control valve, a smoke exhaust Fan, the smoke exhaust channel is used as the main smoke exhaust carrier. The interior of the pipe is coated with a fireproof coating, which has goo...

The invention discloses an air leakage control system of a smoke prevention and exhaust system. The air leakage control system comprises a control center and a smoke exhaust module, wherein smoke exhaust channels are used as smoke exhaust carriers of a main body, the interior of a pipeline is coated with a fireproof coating, and a smoke exhaust fan is arranged in the smoke exhaust pipeline. The control steps are as follows: step 1, measuring the air inlet flow according to a flow meter, and uploading real-time data to the control center; step 2, controlling the air exhaust amount by the control center according to the air volume data; step 3, opening all the smoke exhaust channels, starting a smoke alarm device to judge whether a fire occurs or not, wherein the maximum power of a smoke exhaust motor still cannot meet the smoke exhaust requirement; step 4, if the fire does not occur, manually checking the air volume abnormal reason, if the fire is detected, uploading the air volume information to a cloud database, notifying a nearby fire control center at the first time and reporting the condition; and step 5, opening a fire pipeline through the control center, wherein a high-powersmoke exhaust motor special for fire smoke exhaust is arranged in the fire pipeline.
Description
technical field [0001] The invention relates to the field of smoke prevention and exhaust systems, in particular to an air leakage control system of the smoke prevention and exhaust systems. Background technique [0002] The smoke prevention and exhaust system is composed of air supply and exhaust pipes, pipe wells, fire dampers, door switch equipment, air supply and exhaust fans and other equipment. The smoke prevention system is set in the form of positive pressure in the stairwell. The exhaust volume of the mechanical smoke exhaust system has a direct relationship with the smoke prevention zone. The smoke prevention facilities of high-rise buildings should be divided into mechanical pressure air supply smoke prevention facilities and natural smoke exhaust facilities that can open external windows. [0003] However, the existing smoke prevention and exhaust systems are divided into ordinary commercial smoke exhaust systems and fire-fighting special smoke exhaust systems,...
