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.
當下降時遇到障礙物可停止下降並上升; 可實現煙感報警下滑，溫感報警二次下滑，且溫感報警出掉後可停止二次下滑，可在一個係統內互相轉換。符合標準6.4.6的要求; 垂直啟閉速度：不小於2m/min。其自重下降速度不應大於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.
