安装压力传感器的目的是为了为保证疏散通道不受烟气侵害使人员安全疏散,电梯前室微压差压力传感器生产厂,发生火灾时,电梯前室微压差压力传感器接线,从安全性的角度出发, 高层建筑内 可分为四个安全区:类安全区为防烟楼梯间、避难层;第二类安全区为防烟楼梯间前室、消防电梯间前室或合用前室;第三类安全区为走道;第四类安全区为房间,我公司前室压力传感器8年之久,我公司是你身边的压力传感,欢迎来人来电咨询,





前室压力传感器
YALICHUANGANWI正压送风系统的送风口出风可使楼梯间及消防电梯前室形成正压,电梯前室微压差压力传感器,阻挡***烟气进入人的疏散通道。但是当正压送风系统送风量及送风时间不可控时,正常的逃生路线有可能会因为前室正压过大,防火门无法开启的严重后果。鉴于上述考虑,电梯前室微压差压力传感器生产商,部四川消防科学研究所结合国际经验提出余压值的数据。建筑发生火灾时,防烟楼梯间、避难走道及其消防前室,是人员撤离的生命通道和消防人员进行扑救的通行走道





When the supply air volume and time of itive pressure air supply system is out of control, the normal escape route may be too high because of the itive pressure of the front room, the fire door can not open the serious cequences. In view of the above ciderati, the Sichuan Institute of Fire Science combined with experience to provide data of residual pressure value. By controlling the opening and closing of the by-pass Valve, the differential control system can effectively control the residual pressure of the mechanical pressurized air supply system within the reasonable range required by the national standard ——40-50 PA in the ***oke-proof Stairwell, the front room, the shared front room, the front room of the fire elevator room and the enclosed refuge floor (room) are 25-30Pa.
