前室压力探测器消防前室压力传感器供应商
when the supply air volume&time of itive pressure air supply system is out of control, the normal escape route may be too high because of the itive pressure of the front room, the fire door can not open the serious cequences. in view of the above ciderati, the sichuan institute of fire science combined with experience to provide data of residual pressure value. by controlling the opening&closing of the by-pass valve, the differential control system can effectively control the residual pressure of the mechanical pressurized air supply system within the reasonable range required by the national standard ——40-50 pa in the smoke-proof stairwell, the front room, the shared front room, the front room of the fire elevator room&the enclosed refuge floor (room) are 25-30pa.
前室压力探测器
本产品整体采用四线制连接,安装时将每个单元中的压差控制器并联在四根总线上两根电源线,两根信号线,通过四根总线接入楼顶的旁通泄压阀控制箱中,再通过控制箱控制旁通泄压阀的打开和关闭进行泄压 。在该系统中压差控制器均为独立工作,压差值正常时压差控制器绿色巡检灯亮;当压差控制器所在层压差超过设定值后,压差控制器红色的指示灯亮同时发出蜂鸣报警声。压差控制器在整个巡检和报警过程中均为独立工作方式,任一产品出现损坏均不影响其它产品正常运行。前室压力探测器
