Requirements for the difference between electric fire damper and fire damper

Release Time：2021-07-21

The difference between electric fire damper and fire damper.
The main features of ordinary fire dampers are: fusible pipe fusing action, signal return, manual action and manual reset. It is common for air ducts in ventilation systems to cross fire zones and machine rooms. When the temperature of air flow exceeds 70 degrees in the pipeline, it will close automatically.
Electric fire damper:.
The electric fire damper mainly has the characteristics of fusible pipe fusing action, signal return, manual action and manual reset, which are generally common in places with double functions of smoke exhaust and ventilation. The ventilation pipe of the fire damper plays a role under normal circumstances. When a fire occurs, the fire alarm system is linked, and the fire damper makes the corresponding opening or closing. At this time, the air duct plays the role of the smoke exhaust pipe.
It can be seen from the above that the difference between electric fire dampers and fire dampers is that one of them can use power to make the valve move. They use actuators with different functions to distinguish between the two. There are also two types of electric dampers: one is that only electrical signals can make them move, which requires manual reset, and the other is automatic reset. Of course, it will also be much higher than the price of fire dampers.
Fire dampers are set up on the pipes of ventilation and air conditioning systems, and smoke exhaust fire dampers are set up on the pipes of smoke exhaust systems to prevent the transmission of high-temperature toxic smoke during fire, which will cause the spread of fire and aggravate toxicity.
1. In one of the following situations, the air duct of the air conditioning system should be equipped with a fire damper:.
(1) The pipeline crosses the partition wall of the fire compartment.
(2) The pipeline shall pass through the ventilation and air conditioning machine room and the partition wall and floor slab of the room with important or high fire risk.
(3) The horizontal pipe section at the junction of the vertical air duct and the fire damper of each layer of horizontal air duct (4) The pipeline crosses both sides of the deformation joint.
The fire valve in the above parts will automatically close when the temperature of the gas in the pipeline reaches 70OC in the fire.
2, the separation of the smoke exhaust system:.
(1) In the population of the smoke exhaust room, a smoke exhaust fire damper that can be automatically closed when the smoke temperature exceeds 280OC is set. The smoke exhaust machine shall ensure that it can work continuously for 30MIN at 280OC.
(2) A smoke exhaust fire damper that can be closed by itself when the flue gas temperature exceeds 280C is set on the exhaust branch pipe.
Shandong Xingheng Environmental Technology Group Co., Ltd. is located in Luquantun Development Zone, Dezhou, Shandong, the hometown of FRP in China.
