2, ventilation, air conditioning system, transverse should be set according to each fire zone, vertical should not exceed five layers, when the exhaust pipe is equipped with backflow prevention facilities and each layer is equipped with automatic sprinkler system, the air inlet and exhaust pipe is not subject to this limitation, vertical air pipe should be located in the pipe well.
3, one of the following ventilation, air conditioning system of the wind pipe should be equipped with fire valve
(1) the pipe passes through the partition wall of the fire partition;
(2) through the ventilation, air conditioning room and important or fire risk room partition wall and floor;
(3) on the horizontal pipe section at the junction of the vertical air duct and the horizontal air duct of each layer;
(4) Through both sides of the deformation joint.
4, the action temperature of the fire valve should be 70℃.
5, kitchen, bathroom, toilet and other vertical exhaust pipe, should take measures to prevent backflow or set fire valve on the branch pipe.
6. The pipes of ventilation and air conditioning system should be made of non-burning materials, but the ducts and flexible joints that contact corrosive media can be made of difficult burning materials.
The above is the fire hazard safety knowledge brought by Uetersen for you, about more smoke prevention and exhaust knowledge is still to be updated, hurry to pay attention to us!
