First, smoke smoke damper strong air tightness, mainly reflected in the following four aspects:
1, actuators flexible. The feedback and interlocking signals are accurate.
2 、 the air leakage is low, and the air tightness is good.
3 、 electric opening consumes little current。
4, corrosion resistance, long service life.
Two, in the decoration smoke smoke fire valve can refer to these points for inspection, can reduce the damage later, mainly has the following five points:
1. The fuse shall be installed on the side of the fire danger.
2, smoke fire dampers can be ventilation, smoke exhaust fan interlock, the valve side of the operating mechanism should be less than 200mm of the net space, in order to facilitate maintenance。
3 smoke exhaust fire valve shall be provided with separate hangers to prevent pipe deformation during fire and affect its performance。
天天乐棋牌 4, the installation of smoke fire valve, valve must check whether the operation of the valve is intact, the action is flexible and effective。
5, smoke fire pipe valve should be installed in the wall or floor close to the wind in the fire valve fire partition walls on both sides of the distance from the wall surface should be no more than 200mm, the pipeline fire valve on both sides of the range of 2.0m and the adiabatic material should use non combustible materials.
