Custom production products, according to customer demand production, multi-leaf smoke vent is generally installed in the aisle or smoke prevention front room, usually normally closed, the fire occurs when the smoke sensor probe sends a fire alarm signal, the control centre to the valve on the solenoid connected to the electrical signal to make the valve quickly open, but also can be manually and quickly open the valve for smoke exhaust. Multi-piece mouth and electrical interlock control device, plus construction of ventilation shaft, constitute a complete protection, exhaust system construction. Can effectively remove smoke. Usual multi-leaf smoke exhaust multi-leaf smoke vent actuator, fuse core rod stuck valve shaft (axial) fork plate, so that the valve is in a normally open state. Aluminium air regulating valve can be developed behind the multi-leaf outlet, double shutter with two mutually perpendicular tables adjusted for horizontal and vertical blade angles, adjusting the air diffusion surface to change the range, outlet border width wide border and narrow border two, can be used for special requirements of ventilation systems. When a fire occurs Normally closed multi-leaf smoke vent, air temperature in the duct easily fused, thermal fuse, fuse piece fused, core pin pushed through the ventilation plate, spring, torsion spring valve shaft rotates and closes the valve
