CE Certified Fire Damper for Inert Gas Fire Suppression System - Galvanized Steel

Fire damper type

Introduction:
  Fire damper refers to a device installed on the supply and return air ducts of ventilation and air conditioning systems. It is usually in an open state, but when a fire occurs, it automatically closes when the gas in the duct reaches 70 ℃. Within a certain period of time, it can meet the requirements of fire resistance stability and integrity, and play a role in smoke isolation and fire prevention. Including various products such as gravity fire dampers, fire control valves, fire vents, airtight fire dampers, smoke dampers, electronic self-control smoke dampers, etc.

Installation instructions:

●Before installation, it is necessary to check the appearance quality, control performance, and valve action of the valve, and confirm that it can be used normally before drilling flange connection holes for installation

●During the installation process, it should be ensured that the valve body does not deform, and the valve opens and closes flexibly and reliably after installation.

●The valve body can be installed vertically or horizontally, but regardless of the installation, its blades must be parallel to the ground.

●When installing the valve, attention should be paid to the direction and position. The fuse (melting plate) should be in contact with the airflow before the blade shaft (i.e. located on the windward side of the blade). When installing the self weight fire damper, attention should be paid to the airflow direction sign and it should not be inverted.

●The valve should be reliably fixed in the set installation position to ensure that its working performance is not affected by pipeline deformation and collapse during a fire. If necessary, a lifting bracket should be installed.

●For fire damper with air volume regulation, the valve opening shall be adjusted during middle note.

●When the long side or diameter of the valve body is ≥ 630mm, it must be lifted independently to avoid deformation of the pipeline affecting the flexibility and reliability of valve opening and closing.

●There should be a clear space of<200mm on one side of the valve installation operating device and the side where the spring is installed for operation and maintenance.

●Adopting a remote control operation device, the steel wire rope is protected by a 20mm refractory material tube, with a bending radius of less than 200mm and no more than three bends. The maximum length of the steel wire rope generally does not exceed 6m.
