所谓的正压送风，指的是：建筑前室或楼梯间风流的压力(压强)大于井外或风筒外同标高的大气压力(压强)，压差控制器，其相对压力(压强)为正值，称正压。

在高层建筑楼顶处，即正压送风机进出口连接旁通阀，旁通阀上面设置电动阀门即，消防控制。楼梯间和前室之间安装PY系列的正压送风压力传感器（亦可以说是压力控制器），设定到前室在25~30pa，楼梯在40~50pa（参照防火规范楼梯间和前室压力要求）。当楼梯间和前室测量压差大于设定值时，控制旁通电动阀开启卸压；小于设定值旁通阀门关闭保压。

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 ***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.
