压力传感器正压压力传感器接线

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/stairwell of each floor through the shutters/the air valve. when the ventilation pressure/pressure difference in the fire chamber/stairwell exceeds the set value (25 ~ 30 pa in the front chamber&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)
