The whole pure of the residual pressure monitoring system is to keep the residual pressure in the standard range of the stairwell and the front room, to prevent the harmful smoke from entering, to ensure the normal opening of the fire door, and to ensure the unblocked life passage. Also known as residual pressure measurement and control system, pressure difference measurement and control system, or intelligent residual pressure monitoring system, is a high-rise buildings in the itive pressure air supply system to adjust the fire chamber or stairwell residual pressure value of a set of systematic devices.
所谓的正压送风,电梯前室微压差压力传感器,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,电梯前室微压差压力传感器供应商,控制旁通电动阀开启卸压;小于设定值旁通阀门关闭保压。
