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。

当消防前室或楼梯间的通风压力或压差超过设定值(前室25~30Pa,楼梯间40-50Pa)时,Working principle of itive pressure air supply pressure sensor: under normal circumstances, the itive pressure air supply fan pressurizes the air supply into the air shaft through the air duct (Green Arrow Direction) , the compressed air is then sent to the front room or stairwell of each floor through the shutters or the air valve. When the ventilation pressure or pressure difference in the fire chamber or Stairwell exceeds the set value (25 ~ 30 PA in the Front Chamber and 40-50 PA in the stairwell) , the pressure sensor located on each floor immediately sends a signal to the by-pass pressure relief valve control box, the by-pass Pressure Relief Valve control box opens the by-pass pressure relief valve according to the pressure

加压后的风再分别通过每层的百叶窗或风阀送往每层的前室或楼梯间。当消防前室或楼梯间的通风压力或压差超过设定值(前室25~30Pa,楼梯间40-50Pa)时,位于每层的压力传感器顺即时发出信号报警输入旁通泄压阀控制箱,旁通泄压阀控制箱根据压力传感器的信号打开旁通泄压阀,旁通泄压阀打开后,部分加压送风机送往风管的风通过旁路风管经过旁通泄压阀回到风机前端(红色箭头位置)

The compressed air is then sent to the front room or stairwell of each floor through the shutters or the air valve. When the ventilation pressure or pressure difference in the fire chamber or Stairwell exceeds the set value (25 ~ 30 PA in the Front Chamber and 40-50 PA in the Stairwell) , the pressure sensor located on each floor immediately sends a signal to the by-pass pressure relief valve control box, the by-pass Pressure Relief Valve control box opens the by-pass pressure relief valve according to the signal of the pressure sensor, part of the pressurized air supply fan to the air duct through the Bypass Air Duct by-pass Relief Valve back to the Fan Front (Red Arrow ition)
