电梯前室压力传感器电梯前室压力传感器生产商

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。

电梯前室压力传感器

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

压力传感器

压力控制系统可通过控制旁通阀的开闭，将机械加压送风系统的压力值有效控制在要求的合理范围内-----防烟楼梯间40-50Pa，前室、合用前室、消防电梯间前室、封闭避难层(间)为25-30Pa。The pressure control system can effectively control the pressure value of the mechanical pressurization air supply system within the reasonable range required by the national standard-40-50 PA in the ***oke-proof Stairwell by controlling the opening and closing of the by-pass Valve, the front room, the shared front room, the front room of the fire elevator room and the enclosed refuge floor (room) are 25-30Pa.
