the whole pure of the residual pressure monitoring system is to keep the residual pressure in the standard range of the stairwell&the front room，楼梯间压力传感器生产厂， to prevent the harmful smoke from entering， to ensure the normal opening of the fire door，消防楼梯间压力传感器生产厂，&to ensure the unblocked life passage. also known as residual pressure measurement&control system， pressure difference measurement&control system，/intelligent residual pressure monitoring system， is a high-rise buildings in the itive pressure air supply system to adjust the fire chamber/stairwell residual pressure value of a set of systematic devices.

所谓的正压送风，指的是：建筑前室或楼梯间-的压力(压强)大于井外或风筒外同标高的-压力(压强)，压力传感器生产厂，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-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。
