1. Fire damper can be interlocked with ventilator and exhaust fan.
2. The operating organization side of the valve should have a net space of not less than 200mm to facilitate maintenance.
3. Before setting the valve, it is necessary to check whether the operation organization of the valve is intact and whether the action is sensitive and useful.
4. Fire dampers shall be installed in the air duct section close to the wall or floor slab. The fire dampers on both sides of the partition wall of the fire compartment shall not be more than 200mm from the wall surface. The pipes and their insulation materials within 2.0m on both sides of the fire dampers shall be non-combustible materials.
5. Fire damper should be set up alone hanger, in order to avoid the fire when the deformation of the pipeline affects its function.
What does FD mean in 70 degree fire damper.
FireDamper (fire valve) is a kind of fire valve without air volume adjustment function, is the simplest fire valve, if FVD fire valve fire valve, it refers to the fire valve with air volume adjustment function, and SFVD, refers to the fire control valve with electric function, and BSFVD, refers to the fire control valve with electric function of remote control operation.
280 degree smoke fire damper product use.
Product use of 280 degree smoke fire damper:
(1) The valve can be closed by DC24V power supply (electric smoke exhaust fire damper).
(2) DC24V electric reset after the smoke exhaust fire damper is closed (fully automatic smoke exhaust fire damper, suitable for places inconvenient for manual operation).
(3) Manual shutdown or manual reset.
(4)280 degree smoke exhaust fire damper is normally closed, manually or automatically open when the fire, when the airflow temperature reaches 280 ℃, the temperature sensor action, the valve is closed.
(4) output smoke exhaust fire damper close signal, can be interlocked with other fire prevention equipment.
Fire dampers include gravity fire dampers, fire control valves, fire tuyeres, pneumatic fire dampers, smoke dampers, electronic automatic smoke dampers and other products. Smoke exhaust dampers include smoke exhaust fire dampers, plate smoke exhaust ports (for ceilings), shaft smoke exhaust ports and other products. Fire dampers and smoke exhaust valves are important components in ventilation, air conditioning and smoke control systems, and play important roles in the system mainly in the following three aspects:
1, smoke fire retardant effect.
In the air supply system, the air sent by the blower must be distributed to the branch pipes through the main pipe. In the smoke exhaust system, the smoke enters the exhaust fan after the branch pipes reach the main pipe. When a fire occurs in the building, in the ventilation and air conditioning system, in order to prevent the fire from spreading through the air supply system, when the gas temperature in the air supply system reaches 70 ℃, the fuse fire damper on the fire damper mechanism acts, the valve is also quickly closed to cut off the passage of smoke and fire spreading along the air duct. Similarly, in the smoke exhaust system, when a fire occurs, the smoke exhaust valve is opened to exhaust smoke. In order to cut off the flow of high-temperature smoke in the smoke exhaust pipeline and prevent the fire from spreading to another fire zone, when the temperature of the discharged smoke reaches 280 ℃, the smoke exhaust fire valve and the fuse on the smoke exhaust port operate, and the valve must be automatically closed to prevent smoke, fire dampers and smoke exhaust valves have achieved the function of smoke isolation and fire prevention.
2, the role of regulation.
In the ventilation, air conditioning system piping design, although the calculation, but in the actual project operating conditions if there is a change, you need to adjust the air volume of each part of the system through the fire damper valve, system debugging, the valve opening fixed down, reasonable distribution, to meet the design requirements.
3, start the no-load effect.
