Electrical Fire Damper
The material of electrical fire damper is mainly divided into: carbon steel, galvanized plate. Electrical fire damper is installed in the ventilation, air conditioning system of the supply and return ducts, usually open state, when the fire when the temperature of the smoke in the pipeline reaches 70 degrees closed, and in a certain period of time to meet the requirements of smoke leakage and fire integrity, to play the role of smoke and fire.
Overview
Working Principle:
The working principle of the electric fire damper is mainly based on temperature sensing and control by an electrical actuator.
The electrical fire damper is equipped with temperature sensing elements inside, such as thermal elements, which will respond quickly when the surrounding temperature exceeds the set threshold.
Once the temperature sensing element senses the fire temperature, the fire damper will quickly start the electrical actuator to close the valve and stop the fire from spreading.
Feature:
In case of fire, it can quickly and automatically cut off the fire spreading channel and play the role of smoke and fire blocking.
In addition to the automatic closing function, it is also equipped with a manual operating device, in case of emergency, personnel can manually close the valve through the manual operating device to increase the flexibility of emergency control.
An alarm signal will be triggered at the time of closure to notify the building's fire protection system and management personnel to take timely fire-fighting and evacuation measures.
