紫旭空调没有中间商 电梯前室微压差压力传感器供应商

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，电梯前室微压差压力传感器批发， and to ensure the unblocked life passage. Also known as residual pressure measurement and control system，电梯前室微压差压力传感器安装位置， pressure difference measurement and control system， or intelligent residual pressure monitoring system，电梯前室微压差压力传感器供应商， 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.

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 smoke-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.
