Fire dampers to avoid pipeline grease build-up Closed demand conditions

Release Time：2021-07-15

Kitchen fume will affect the health of many people. Many people often set up smoke exhaust fire dampers to reduce the damage of fume. Before the smoke exhaust fire dampers are installed, it is necessary to check whether each organization of the air outlet is in good condition. The air outlet is made of non-combustible materials. The rolling parts should be made of corrosion-resistant metal materials and roll sensitively.
At present, the fuel of kitchen stoves in hotels, restaurants and restaurants is mainly gas or oil. Once the stove or fuel transportation pipeline leaks, a fire will break out in case of open flame.
Smoke hood and smoke pipe grease accumulation, in case of open fire caused by commercial kitchen in the use process, the smoke hood and air duct will gradually accumulate grease due to the influence of oil smoke, fire damper when the smoke hood and air duct grease encounter open fire, easy to cause burning, and through the fan, air duct and other ways to extend and cause fire.
With the progress of public awareness of fire protection and the need to maintain the safety of citizens' lives and property, the prevention of commercial kitchen fires has attracted the attention of relevant departments. It is necessary to strengthen the construction of fire safety design, strengthen the control and monitoring of fuel, and regularly clean pipelines to avoid excessive oil temperature and equip rescue equipment.
After the valve body device of smoke exhaust fire damper is used, it should be checked regularly according to relevant fire safety handling requirements to check whether the orientation of the blade is correct, whether there is deformation and movement. When the operating power is turned on, the valve cannot be actively closed or opened. Check and adjust according to the following sequence, (fire damper 1) active closing device: (or active opening device) ① electromagnet check: whether the power is on and the stroke is correct, whether the moving iron core is sensitive, ② check the electrical connection circuit: whether there is open circuit or poor contact, ③ check the micro switch: whether the micro switch contact is connected in the correct position,(2) valve body part: ① whether the outer frame device of the valve body is correct, if any paint is found to fall, repair it in time, ② whether the gap between the blade and the outer frame is suitable, whether the rolling part of the blade is sensitive, ③ whether any foreign matter falls into the valve body.
The fire control valve can satisfy the requirements of smoke leakage and fire integrity within a certain period of time, and play the role of smoke isolation and fire resistance.
1. The valve of the fire control valve is normally open. The DC24V power output by the control fire valve system center can make the valve actively closed, and can interlock for ventilation. The air conditioning fan stops and outputs a closed signal.
2. At 70 ℃, the temperature fuse acts and the valve is closed. Press the manual button of the actuator on the valve to close the valve.
3. When the fire control valve is required to be opened again, the electrical signal can actively reset the valve to the original open condition, the reset button> 12N.m, and can interlock ventilation, and the air conditioning fan is actively opened.
4. The valve can be centrally controlled by the central control room or actively controlled by the unit.
5. The conditioning equipment on the organization can be divided into 18 °,36 °,54 °,72 °,90 °.
