Fire valve operation problem maximum use value

Release Time：2021-07-21

Fire contact is connected with fire dampers and smoke exhaust fire dampers, so which needs to be controlled and which do not need to be controlled.
1. When the fire damper is electric, 24V is required to be closed. For example, when the fire damper is 70 ℃, only the response signal is required when the fuse is active fuse. Usually, the fire damper is installed behind the static air conditioner press and is normally open. When a fire breaks out, its 70 fuse is fused and the valve is closed, blocking the air supply from the air conditioner to the fire scene. When the fire damper is closed, the signal is responded to the host.
2. The smoke exhaust valve is usually normally closed. It requires 24V power supply to operate and open in case of fire. The smoke exhaust valve is installed in front of the fan. It is normally closed. It is usually a fully active solenoid valve. It is opened with a module and has a response signal. Usually, when the fan is linked, the fan will not operate until the smoke exhaust valve is completely opened.
3. When the smoke exhaust fire damper is normally open, when the temperature reaches 280 ℃, only the fire damper needs to respond to the signal. When the smoke exhaust fire damper is normally closed, 24V is required to open the smoke exhaust fire damper. When the temperature reaches 280 ℃, the smoke exhaust fire damper moves for the second time (closed).
The maximum use value of the fire valve.
1. Before installing the fire damper valve, you must check whether the operating mechanism of the valve is intact and whether the action is flexible and effective.
2. One side of the valve's operating mechanism should have a net space of not less than 200mm to facilitate maintenance. If the valve is connected with the fan, the fire damper should be equipped with a double micro switch device.
3. The fire damper can be interlocked with the ventilator and the smoke exhaust fan.
4. The fire damper shall be installed in the air duct section close to the wall or floor. The fire damper on both sides of the partition wall of the fire partition shall not be more than 200mm from the wall surface. The pipeline and its thermal insulation material within 2.0m on both sides of the fire damper shall be made of non-combustible materials.
