Design significance and wiring method of smoke exhaust fire damper

Release time:

2021/07/20 13:37

Fire damper is installed in the ventilation, air conditioning system to send, return air pipe road, usually open state, fire when the gas temperature in the pipe reaches 70oC automatically shut down, in a certain period of time to meet the fire stability and fire integrity requirements, the role of smoke fire valve.

Fire damper related knowledge and construction installation

Release time:

The actuator of the fire damper is composed of a shell, a blade adjustment mechanism, a clutch, a temperature fuse, etc. It uses the principle of mechanical transmission to work. The fire damper must play a role in preventing fire, must be installed correctly, and must understand its related knowledge.

The role and acceptance of various fire dampers

Installed in the central air-conditioning air duct system, the working principle is to use the temperature control of the fusible alloy to close the valve by using the action of gravity and the action of the spring mechanism. When a fire occurs, the flame invades the air duct, and the high temperature melts the fusible alloy on the valve. Or make the memory alloy deform to make the valve automatically close, which is used for occasions where the air duct and the fire zone run through.

Set smoke exhaust fire damper at the connection of smoke exhaust fan and smoke exhaust pipe, and set smoke exhaust valve at the end of smoke exhaust pipe. Note that smoke exhaust valve and smoke exhaust fire damper are devices with completely different functions. Smoke exhaust valve is usually closed, opened in case of fire, and linked with alarm host. The opening condition is that the automatic alarm system has a fire alarm (smoke or fire damper temperature detection signal is sent to the control center host), the fire alarm host is in automatic state, and the exhaust valve is automatically open, the linkage smoke exhaust fan is started, the smoke exhaust fire damper is usually open, and it is also open in case of fire. However, when the smoke temperature reaches 280 ℃, the smoke exhaust fire damper is automatically closed, and the linkage fan that has been opened stops running.

Structure of Fire Damper and Its Function in Air Conditioning

Release time:

2021/07/20 11:56

The structure of the fire damper is mainly composed of a valve body and an actuator. The valve body is composed of a shell, a flange, a blade and a blade linkage mechanism. The actuator is composed of a shell, a blade adjustment mechanism, a clutch, a temperature fuse, etc. The actuator controls the rotation of the blade through a metal fusible sheet and a clutch mechanism.

Actuator and type of smoke exhaust fire damper
