Product Description

Motorized Fire Damper is an important fire equipment, which is widely used in the supply and return ducts of ventilation and air conditioning systems. The following is a detailed introduction to the fire valve:

Material and structure

The material of the fire valve is mainly divided into carbon steel and galvanized sheet, which have good corrosion resistance and high temperature resistance and can meet the requirements of fire fighting equipment. Its structure usually includes valve body, blade, actuator and other parts, through the electric actuator to control the opening and closing of the blade, to achieve fire protection function.

Working principle

Motorized Fire Damper is always open. When the air temperature in the ventilation duct reaches the set threshold value (usually 70℃), the temperature detector will act and close the valve rapidly through the electric actuator, thus blocking the spread of fire and smoke. In addition, the fire valve can also be remotely controlled by DC24V power supply, or manually closed and reset.

Use and maintenance

In order to ensure the normal operation and effectiveness of the fire valve, regular inspection and maintenance are required. The inspection contents include but are not limited to the tightness of the valve, the flexibility of the actuator, the accuracy of the temperature detector, etc. At the same time, it is also necessary to carry out regular cleaning and maintenance work on the fire valve to extend its service life and improve its performance.

To sum up, Motorized Fire Damper is an important fire equipment with the functions of smoke and fire suppression, low air leakage, electric opening, manual control and signal output. It plays an important role in the ventilation and air conditioning system of buildings, and is one of the important facilities to ensure the safety of personnel's life and property.
