豪鲁邦传感仪器有限公司 带开关量输出防烟电梯前室压力控制器/消防楼梯间压力
when the supply air volume&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，电梯前室压力传感器， 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&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，前室压力传感器， the shared front room， the front room of the fire elevator room&the enclosed refuge floor (room) are 25-30pa.
the whole pure of the residual pressure monitoring system is to keep the residual pressure in the standard range of the stairwell&the front room，消防电梯前室压力传感器， to prevent the harmful smoke from entering， to ensure the normal opening of the fire door，&to ensure the unblocked life passage. also known as residual pressure measurement&control system， pressure difference measurement&control system，/intelligent residual pressure monitoring system， is a high-rise buildings in the itive pressure air supply system to adjust the fire chamber/stairwell residual pressure value of a set of systematic devices.
