The latest Taiyuan positive pressure air blower quotation Detong Air Conditioning Equipment Factory
It is usually installed on the wall of the new staircase front room and smoke exhaust shaft, and can also be installed on the side of the smoke exhaust system pipe or at the end of the air duct.
Main functions and features: Normally closed, electric or manual opening. Output start signal. Manual reset off. ℃ temperature sensor operates and the valve closes again. The thin mechanism is adopted to reduce the size of the operation box and increase the effective ventilation and smoke exhaust area.
3 Main technical parameters Edit action voltage/current:.. Air leakage volume:/·≤ (at pressure difference). Thermosensor operating temperature ℃.
Main components of structure editor: valve body, valve disc, bushing, thin actuator, grille panel. When B size ≥, assemble an actuator. Specifications and dimensions (×B×)[] Function: When a fire occurs, the electric actuator inside will open the air vent, the temperature sensor smoke sensor or manual fire alarm will turn on, and the positive pressure fan on the top of the tower will automatically turn on. The air supply shaft is pressurized to supply air. The front room of the stairs will continuously supply air to the front room through the positive pressure air supply port to maintain the positive pressure in the front room and ensure that the smoke will not spread in this area and give people Room to escape. When the temperature is higher than ℃, there is no possibility for people to escape. The internal fuse will blow and the air vent will automatically close to prevent the spread of fire. Application: The national fire protection and smoke exhaust design specifications for high-rise buildings stipulate that the following locations should be equipped with independent mechanical smoke exhaust systems
Smoke-proof stairs that do not have natural smoke exhaust conditions, fire elevator front rooms or shared front rooms.
Smoke-proof stairs that use natural smoke exhaust do not have a front room for natural smoke exhaust.
