Precautions For The Use Of Smoke And Fire Dampers?

Smoke and fire damper opening state, some cases need to be normally open, some need to be normally closed. But the main thing is that in case of fire, it can block the spread of fire. At the same time it can reduce the fire, to achieve the role of safety, can be more sensitive to open.

So what do you need to pay attention to when using smoke and fire dampers? As a professional Smoke And Fire Dampers Making Machine in China, KINGREAL offers the following recommendations:

1. Before installing the valve body, check whether the valve and the mechanism are intact, confirm that all aspects of the valve are normal, and then install it. When installing the smoke and fire damper, the valve body side should be reserved for the position, generally greater than 350mm of net space, to facilitate regular action test and inspection.

2. In use, the opening action test should be conducted periodically, and it is recommended that it be conducted once every six months to a year. Operation test includes the use of through number to make the valve open or manually open, the valve should output through number after operation. The valve body should have a separate support hanger to avoid deformation of the air duct at high temperatures and affect the valve function.

3 . When the valve frame is installed on the suspended ceiling, which is produced by KINGREAL Metal Ceiling Tile Production Line should be an inspection door hole below the observation. The general size should not be less than 45 × 45cm, such as limited conditions, ceiling access hole can also be reduced to 40 × 40cm. circuit and remote control cable protection sleeve should be selected from D20 ordinary plastic pipe.

4. The bending radius of the control cable set is greater than 250mm, and the bending is generally less than or equal to 2 places. Smoke vent (air outlet) valve frame size on the wall, the valve frame should not bear the weight, otherwise the valve will fail to deform after extrusion.
