The working principle is to use the temperature of the alloy can easily melt open to control the use of gravity and the role of the spring mechanism to close the valve. When a fire occurs, the flame invades the air duct and the high temperature melts the fusible alloy on the valve or causes the deformation of the memory alloy to automatically close the valve for occasions where the air duct and the fire protection zone are penetrated. Fire damper installed in the exhaust pipe exhaust valve, usually exhaust valve normally closed, when a fire occurs, through the floor partition set smoke detectors to detect a large number of continuous smoke information to open the exhaust valve linkage, And feedback signal to the fire monitoring host, linkage to open the corresponding area of the exhaust fan, in order to achieve the purpose of smoke. Fire valve installed in the ventilation, air-conditioning system to send, return air lines, usually open state, when the fire when the pipe gas temperature reaches 70 ℃, the fusible link, the valve automatically closed under the torsion spring force, Time to meet the fire-resistant stability and fire integrity requirements, play the role of smoke valve fire. When the valve is closed, the output closes. And great progress has been made. However, long-wave areas in solar energy have not been fully utilized. In the car's fuel, mainly gasoline as the main fuel. In the car's internal combustion system, will be discharged after the use of polluting gases. If the heat in the solar energy into hydrogen and methane from the water to make the "activation energy", smoke fire damper installed in the exhaust pipe system, usually generally closed state, fire manual or electric open, play a role in smoke , When the exhaust pipe flue gas temperature reaches 280 ℃ closed, within a certain period of time to meet the fire resistance stability and fire integrity requirements, play a role in the smoke valve.

Automatic exhaust smoke damper role in underground ventilation, air-conditioning system of fire, exhaust valve with automatic fire alarm equipment and gas fire extinguishing system linkage control functions. Each fully automatic smoke damper has two independent electric control signals, respectively, by the EMCS, gas consumption monitoring system, and made great progress. However, long-wave areas in solar energy have not been fully utilized. In the car's fuel, mainly gasoline as the main fuel.
