指标性能

        采用各层消防栓系统供水,最佳供水压力为0.20Mpa,布置到卷帘侧面,布水强度为025m3/m2.h,供水时间为3.00hs,耐火极限(h)> 3.00;喷淋角度与钢制帘面呈15°。


适用范围

        适用于以卷帘背火面温升为限定条件(平均温升≤140℃。最高温升≤180℃、耐火极限为3.0h)的工业与民用建筑中的防火区域分隔。


Product introduction

The shutter has a set of independent water spray device, and the spray pipe takes water from one side. The system water supply pipe uses dual-face hot galvanizing steel pipe, with a pipe diameter of 025.4mm,with bores of 02mm on the pipe and bore spacing of 80mm (2 rows).The horizontal distance between the spray pipe and the shutter plate is 100mm.The system is conneoted with indoor fire hydrant pipe network.

Performance index

? he fire hydrant system of each floor supplies water to it, with optimum water supply pressure of 0.2Mpa.The fire hydrant is arranged at the side of the shutter, with a spraying intensity equal to or more than 0.25mmh, and the supply duration is 3.00h.

? ire resistant limit (h): > 3.00.

?The angle between the spray direction and the steel curtain is 15°.

Scope of application

It is applicable to fireproof compartments in industrial and civil building, which has the qualification according to curtain temperature on the back(average temperature rise ≤140°C, Max temperature rise ≤180°C fire resistance limit≥3.0h)
