通过对排烟风机、排烟口(阀)控制的分析得出,提高排烟口(阀)控制的可靠性以及提高排烟口(阀)与排烟风机联动控制的可靠性,是保证机械排烟系统具有高的可靠性的关键。结合工程实例,对大空间建筑机械排烟系统联动控制进行了可靠性设计。大空间建筑如体育馆、展览馆、大型商场、厂房及建筑内的大空间区域等,一旦发生火灾,烟气漫延速度快,危害性大。因此,必须尽快排除烟气。为了保证建筑内人员的安全疏散和扑救工作的顺利进行,建筑物内一般都设置
Through the analysis of exhaust fan and exhaust port (valve) control, it is concluded that improving the control of exhaust port (valve) and improving the reliability of linkage control between exhaust port (valve) and exhaust fan ensure that the mechanical The key to high reliability of the smoke extraction system. Combined with the engineering example, the reliability design of linkage control of smoke exhaust system in large space construction machinery was carried out. Large space buildings such as stadiums, exhibition halls, shopping malls, factories and large space within the building, in the event of a fire, smoke spread rapidly, harmful. Therefore, the smoke must be eliminated as soon as possible. In order to ensure the safe evacuation of personnel in the building and the smooth progress of the fighting, the buildings are generally set
