Fire damper Installed on the supply and return air ducts of ventilation and air conditioning systems, the valve remains open during normal operation. In the event of a fire, when the gas temperature inside the pipes reaches 70°C, the fusible link melts, causing the valve to close automatically under the force of the torsion spring. It can meet the requirements for fire resistance and integrity for a certain period of time, serving as a smoke and fire barrier. When the valve is closed, it outputs a shutdown signal. Smoke and fire damper Installed on the smoke exhaust system piping, generally in a closed state during normal operation, manually or electrically opened during a fire to facilitate smoke exhaust. Closes when the smoke pipe temperature reaches 280°C, meeting fire resistance stability and integrity requirements for a certain period, a valve that serves as a smoke exhaust function. Product Principle Installed in the central air conditioning duct system, the working principle is temperature control via fusible alloy, utilizing the force of gravity and the action of a spring mechanism to close the valve. In the event of a fire, as flames enter the duct, the high temperature melts the fusible alloy on the valve or causes the shape-memory alloy to deform, automatically closing the valve. This is used in situations where the duct passes through fire compartments.
