Smoke fire damper is mainly used for ventilation, air conditioning system on the duct, usually in the "normally open" state, when the air temperature reaches 70 ℃, through the valve fuse action and automatically shut down.

And the safety device is formed by the mutual matching electromagnet, swing rod, and swing frame with rotating column. The cam is clamped on the belt, and the upper and lower housings with springs are installed on the hollow shaft. The handle will The upper and lower housings are connected as a whole and cooperate with the fuse to form an operating device. It also includes the gear on the motor shaft meshing with the gear on the controller shaft through the gear set, the rotating shaft on the gear of the controller is connected with the rotating shaft fixed on the hollow shaft through a pull rod to form an electric operating mechanism, which is electrically reset and operated, and is more convenient and rapid to use.

It seems that the actuators of fire dampers may be the same, especially for fire dampers of the same model, which may have the same parameters. However, if wholesale is really to be carried out, there will certainly be great differences in price. After all, the unit price is slightly lower, and the overall investment will be greatly affected. If we want to buy such fire dampers, we must first ensure the quality, so it is also very important to choose the right brand products.

Use and Working Condition of Electric Fire Damper

Release time:

In the ventilation and air conditioning system, a normally open electric fire damper is generally set in front of the fan. When the fire damper is fused and closed, the fan is jointly closed to prevent the fan from continuing to work after the air duct is closed, thus achieving the effect of protecting the fan. The subway ventilation and air conditioning system is relatively complicated, and the linkage functions of the normally open electric fire damper and the fan under different systems are different.

Gravity fire dampers are divided into rectangular and circular types. Fire dampers are normally open. When the valve needs to be opened from scratch, loosen the bolt in front of the self-locking reed, hold the operating rod in hand, shake up the valve plate or blade, connect the fusible sheet, straighten the self-locking reed, and tighten the bolt to recover the normal working condition of the fire dampers.

Effect and key setting of smoke exhaust fire damper

Smoke exhaust fire damper is to use the temperature control of fusible alloy to close the valve by the action of gravity and tension spring organization. When a fire breaks out, the flame invades the air duct, and the high temperature melts the fusible alloy on the valve, or the memory alloy is deformed to automatically close the valve. It is used for occasions where the air duct runs through the fire compartment.
