The mechanical pressurization system plays a vital role in a fire protection system.The key is to use the residual pressure control system to maintain a relatively stable residual pressure in the smoke-proof area.In this paper,the excessive pressure in the smoke-proof area and the difficulties in pipeline layout are analyzed for implementing control with a bypass pressure relief valve+residual pressure controller for the residual pressure control system and some optimized controls actually applied are proposed for reference.
