The design function of the rolling shutter door is linked with the temperature fuse device and directly linked with the fire control center control room; the smoke alarm is realized, the rolling shutter automatically drops to the ground 1.5-1.8m height, with a delay of 180 seconds (adjustable) and then closes in the descent.
当下降时遇到障碍物可停止下降并上升; 可实现烟感报警下滑，温感报警二次下滑，且温感报警出掉后可停止二次下滑，可在一个系统内互相转换。符合标准6.4.6的要求; 垂直启闭速度：不小于2m/min。其自重下降速度不应大于9.5m/s，平均噪音85dB。
When falling, it can stop falling and rising when encountering obstacles; it can realize the sliding of smoke alarm, the second sliding of temperature alarm, and it can stop the second sliding after the temperature alarm falls out, which can be switched between each other in a system. Meet the requirements of standard 6.4.6; vertical opening and closing speed: not less than 2m / min. The self weight falling speed shall not be greater than 9.5m/s, and the average noise shall be 85dB.
Before installation and welding of stainless steel parts, it is necessary to carefully clean the oil, dust and other debris on the surface. Argon arc welding shall be used as far as possible during welding. If manual arc welding is adopted, small current quick welding shall be applied, and arc striking in non welding area is strictly prohibited. The ground wire used shall be in a proper position and connected firmly to avoid arc burn on the surface or excessive burn area; during welding, it shall take measures to prevent splashing.
After welding, when cleaning welding slag, stainless steel flat shovel shall be used instead of carbon steel flat shovel. The weld joint shall be carefully polished to make the smooth transition between the weld joint and the base metal surface, and there shall be no slag, air hole, undercut, spatter, crack, incomplete fusion and other quality defects.
