摘　　要：介绍了一种无料钟炉顶上密封阀夹紧力智能控制系统。通过在炉顶称量罐上安装压力变送器,在均压过程中实时检测均压气体压力,计算均压气体对上密封阀板的盲板力,并在液压系统中设置比例减压阀,建立均压气体压力与液压系统压力之间的比例平衡关系,通过计算机系统智能动态调节上密封阀液压系统的压力,降低并均衡上密封阀板与阀座之间的夹紧力,延长上密封阀板、阀座及上密封阀夹紧机构的使用寿命,降低无料钟炉顶上密封阀的故障率,从而保障了高炉炉顶设备运行的高效性。An intelligent control system for the clamping force of a sealing valve on the top of a bell-less furnace is presented.By installing a pressure transmitter on the weighing tank of the furnace top,detecting the pressure of the equalizing gas in real time during the equalizing process,calculating the blank cup pressure of the equalizing gas on the upper sealing valve plate,and setting up a proportional pressure-reducing valve in the hydraulic system to establish the proportional balance relationship between the equalizing gas pressure and the hydraulic system pressure.Through intelligently and dynamically adjusting the pressure of the hydraulic system of the upper sealing valve by means of a computer system,reducing and equalizing the clamping force between the upper sealing valve plate and the valve seat to prolong the service life of the upper sealing valve plate,the valve seat and the upper sealing valve clamping mechanism,reducing the failure rate of the sealing valve of the bell-less top,so as to guarantee the high efficiency of the operation of the equipment at the top of the blast furnace.
