Fire control valve dampers installed in the ventilation, air conditioning system, the return air duct on the road, usually was turned on, when the gas pipeline fire when the temperature reached 70 ℃, fusible film fuse, the valve automatically closes under the force of the torsion spring within a certain period of time to meet the fire resistance stability and fire integrity requirements, from smoke fire retardant valves. When the valve is closed, the output off signal to send fire control valve fire dampers installed in the ventilation and air conditioning systems, return air duct on the road, usually was turned on, vertical multi-leaf delivery outlet when the gas pipeline fire inside when the temperature reached 70 ℃, easily fuse blows, the valve automatically closes in the torsion spring force, in a certain period of time to meet the fire resistance stability and fire integrity requirements, from smoke fire retardant valves. When the valve is closed, the output off signal. Smoke damper: Install exhaust system pipeline, usually generally was closed when the fire manual or electric opening, from the smoke effect. Our company is specialized in producing fire exhaust valve manufacturers, since the market has been deep. loved by the public, and now manufacturers sell low-cost fire exhaust valves, are welcome. Main construction fire exhaust valve installation: 1. fire exhaust valves and fan, exhaust fan interlock. 2. The operation of the valve mechanism side should be not less than 200mm of clear space to facilitate maintenance. 3. The valve must be checked before installing the valve operating mechanism is intact, the action is flexible and effective. 4. fire exhaust duct segments valve should be installed in close proximity to the wall or floor, the fire dampers on both sides of the partition wall from the wall surface should not exceed 200mm galvanized sheet multi-leaf delivery outlet, fire dampers on each side 2.0 pipes and insulation should be used within the m-wide non-combustible material.
