排烟防火阀知识分享:
工程常开式电动防火阀有两种:一种选用FF1编号,是常开式电动防烟防火阀,正常状况常开,电动操作,电动或手动复位,70°C熔断封闭防火阀,用于送、排风管道;另一种选用FP1编号,是常开式电动排烟防火阀,正常状况常开,电动操作,电动或手动复位,280°C熔断封闭防火阀,用于排烟管道或排风兼排烟管道。
 
两种防火阀的差异在于熔断器的熔断温度不同。地铁工程常开式电动防火阀作业原理  常开式电动防火阀的状况输出端子有3个:开状况信号(A)、关状况信号(C)和公共端(B)。正常状况时,防火阀坚持打开状况,公共端(B)与开状况信号输出端(A)之间导通,控制体系判别防火阀处于打开状况。
