We all know that fire valves and vents are one of the indispensable equipment in fire protection, heating and ventilation engineering, playing a vital role. The valve and air outlet belong to two different products, which are installed in different positions and play different roles. However, there is another product that often appears in the fire protection and HVAC engineering, and we should not be unfamiliar with it. That is, the multi leaf smoke outlet and the multi leaf air supply outlet, which can be said to be the combination of the valve and air outlet. There is only one word difference between the multi leaf smoke exhaust outlet and the multi leaf air supply outlet, and the processing technology and practice are roughly the same, but there are still some differences in the installation position and the role played. Let's talk about the differences between the multi leaf smoke exhaust outlet and the multi leaf air supply outlet.
Multi leaf smoke exhaust outlets are generally installed in corridors, elevator car openings, pipelines, or in front of smoke exhaust chambers or in rooms without windows. The difference is that when a fire occurs, it will exhaust the smoke from the stairway or corridor to the outside. The work of air exhaust and smoke exhaust is carried out by the centrifugal fan in the system software. It is responsible for opening the air outlet when receiving the data signal to complete its task.
Most of the multi leaf air supply outlets are installed at the stairway or aisle of the building, which is usually closed. Once the outlet is opened by remote control of DC24V DC power data signal in case of a fire accident, the relative centrifugal fan in the system software will coordinate to transport the smoke in the smoke exhaust duct immediately.
The purpose of multi leaf smoke exhaust outlet and multi leaf air supply outlet is to exhaust smoke through ventilation duct and transport fresh air in case of fire, so as to ensure that trapped people and rescue workers in the building can quickly exhaust toxic gases, thick smoke, hazardous air pollutants floating in the air and other harmful gases to the body during fire fighting and rescue, and ensure that there is an endless stream of fresh air coming in, Ensure that all trapped people breathe normally.
In fact, smoke vents are also divided into several different types: plate type smoke vents, multi blade smoke vents, among which there are differences between near control and remote control. The reason why these different types of smoke vents have always appeared in major projects is that they play different important roles in different fields.
