The difference between the front pressure air outlet and the smoke discharge valve
What is the air outlet? I believe most people have no concept for this word? In fact, it is a fan that places the air in the escape corridor. When the accident occurs, sending the air in the corridorIn the wind, the corridor is in a positive pressure, which means that the air pressure in the corridor is higher than other places. The smoke will not exudes in and causes personnel to suffocate to ensure safety.
It is different from the smoke exhaust fan. The smoke exhaust fan is a fan used to smoke the smoke in the building during an accident to improve the vision of the building and drive away the smoke to facilitate the fire extinguishing.It is also different from the replenishment. The more the air channel connecting the lower layer and the outside world, the less the lower layer. The use of the hood alone will cause a large negative pressure, reduce the smoke efficiency, and the smoke is discharged slowly.Use a supplementary fan to send in the outside air to reduce negative pressure, making smoke easier to discharge.
The positive pressure air outlet adopts a thin -shaped mechanism to reduce the size of the operation box and improve the effective ventilation smoke area.And usually closed, electric and manually.When the output is output, you need to turn on the signal, and you need to manually reset and close it when you close it.When the temperature sensor movement temperature reaches 280 ° C, the valve is closed again.The scope of applications is wide, and in the smoke -proof stairs that do not have natural smoke, the front room of the fire elevator may be used in the front room, and the smoke -proof staircase with natural smoke is used.
