Attention and importance of 280 degree fire damper device

Release time:

2021/07/20 11:28

The 280-degree fire damper shall be normally open, also known as high-temperature fire damper. Generally, it is installed in a ventilation pipe with high-temperature environment. When the temperature reaches 280 ℃, the fusible alloy melts and the valve is closed. At the same time, it can be controlled by 24V electrical signal. If the 280-degree fire damper is normally closed, the control center of the device gives an electrical signal to open the smoke exhaust when the smoke exhaust pipe starts. When the temperature reaches 280 ℃, the fusible alloy melting valve is closed, is a secondary action of the valve, used in the exhaust system pipe, usually open, fire smoke, when the smoke temperature reaches 280 ℃, the fire valve closed, interlocking fan closed.

The use of smoke exhaust fire dampers has improved our safety assurance. All of them are in HVAC cities in our country. Smoke exhaust fire dampers can be seen in all major professions. The use of the fire dampers has greatly improved our safety assurance. However, leakage of the joint surface of smoke exhaust fire dampers may also occur during use. What are the main reasons for this phenomenon?

The 70-degree fire damper is a kind of equipment to avoid the spread of fire. The 70-degree fire damper is usually in a normally open state. In general buildings, it is usually installed at the entrance of the fan used for both the smoke exhaust system and the ventilation and air conditioning system. When the temperature of the airflow in the pipeline rises to the fuse, the core rod is pushed by the spring, and the fork plate is disconnected. The valve shaft is rolled by the torsion spring effect to close the valve, if the air volume needs to be adjusted to be very small, the valve opening can be adjusted through the handle linked with the valve shaft, and the butterfly mother can fix its position when the requirement is reached, and a closed electrical signal output device can be added according to the user's requirements to become a 70-degree fire damper.

The distinction between the function and structure of smoke exhaust valve

Smoke exhaust fire dampers and fire fighting components are generally installed on the pipelines of mechanical smoke exhaust systems. They are usually open. When a fire breaks out, they are open to exhaust smoke. When the smoke temperature in the smoke exhaust pipeline reaches 280 degrees, they are closed, and the requirements for smoke leakage and fire resistance integrity are satisfied within a certain period of time, so as to prevent smoke and fire.
