湖南消防楼梯间压力传感器接线诚信企业 紫旭空调传感器批发

当楼宇住宅火灾发生时，人员走向是:室内→走廊→前室→楼梯间。当量较大时，电梯前室和楼梯间的防火门会出现同时开启的情况，这时要求正压送风的流向是:楼梯间→前室→走廊，这样才能起到防烟的效果。

压力传感器根据其传感器结构，分为机械式压力传感器和电子式压力传感器。当楼宇住宅火灾发生时，人员走向是:室内→走廊→前室→楼梯间。当量较大时，电梯前室和楼梯间的防火门会出现同时开启的情况，这时要求正压送风的流向是:楼梯间→前室→走廊，这样才能起到防烟的效果。

When the supply air volume and 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 and 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 and the enclosed refuge floor (room) are 25-30Pa.
