消防名词的解释（Explanation of fire terms） Basics: some explanations for fire terms Smoke control way, various buildings adopt smoke control and exhaust smoke basic way, generally have natural smoke exhaust, mechanical smoke exhaust, mechanical pressurization, air supply, smoke prevention, airtight, smoke control and so on. The principle of closed smoke proof and airtight smoke prevention is to make use of the sealing property of the room to extinguish the fire and prevent the spread of fireworks. This smoke is generally applicable to smaller, and the wall and floor good fire resistance, good sealing room, fire personnel can quickly complete the evacuation, and can immediately fire the fire room enclosed place keeper. Such as houses, hotels, dormitories and so on. Mechanical and air ventilation machinery are pressurized gas through the ventilation machine produced by flow and differential pressure to control the flow of smoke, the fire in the building, the area to fire outside the air pressure, make it keep a positive pressure to prevent smoke flue gas invasion. This method is widely used in building evacuation staircase and antechamber. Mechanical exhaust smoke mechanical exhaust way can be divided into mechanical smoke exhaust, natural air way and mechanical smoke exhaust, lower pressure and way. Mechanical smoke exhaust and natural air feeding mode, that is, smoking smoke is installed at the upper part of the space, and mechanical exhaust is carried out by using exhaust fan. This method is suitable for smoke control in large building spaces. The utility model is characterized in that a smoke exhaust opening is arranged at the upper part of the space when the fire is arranged, and the air is supplied at the lower part to raise the internal pressure and eliminate the smoke. This method is more applicable to smoke control of high buildings or large construction spaces which is important in the design of smoke control and exhaust. Natural ventilation natural ventilation is b
