压力控制系统可通过控制旁通阀的开闭,将机械加压送风系统的压力值有效控制在要求的合理范围内-----防烟楼梯间40-50Pa,前室、合用前室、消防电梯间前室、封闭避难层(间)为25-30Pa。这样既阻止了***烟气的进入,也确保了防火门在需要人员疏散时可以正常开闭。压力控制系统可通过控制旁通阀的开闭,将机械加压送风系统的压力值有效控制在要求的合理范围内-----防烟楼梯间40-50Pa,前室、合用前室、消防电梯间前室、封闭避难层(间)为25-30Pa。这样既阻止了***烟气的进入,也确保了防火门在需要人员疏散时可以正常开闭。

When the supply air volume and time of itive pressure air supply system is out of control,消防前室压力传感器接线, 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,前室微压差压力传感器接线, 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 ***oke-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.
