摘要： In a throat stopper for shaft furnaces, in particular blast furnaces with two hoppers of which an upper hopper is rotatable through a drive device, the upper hopper is designed, by means of a stationary hood equipped with charging flap valves, as a sluice chamber to be closed pressureproof. For sealing the stationary hood relative to the rotatable upper hopper, there is disposed, at the hood, a peripheral flexible inflatable bellows. The bellows can be pressed against the wall of the upper hopper pneumatically or hydraulically. While material is being charged in the upper hopper, one of the charging valves is open and the bellows is pressureless. During, or shortly thereafter, the charging, the upper hopper is rotated. For during the lower hopper, the valves of the upper hopper are closed, bellows is inflated, and the upper hopper is hopper are closed, bellows is inflated, and the upper sluice chamber is pressurized.
摘要翻译：在用于竖炉的喉部止动器中，特别是具有两个料斗的高炉，其中上料斗可以通过驱动装置旋转，上料斗通过装有充气阀门的固定罩设计为闸门室封闭防压。为了相对于可旋转的上料斗密封固定罩，在罩处设置有外围柔性的可充气波纹管。波纹管可以气动或液压地压在上料斗的壁上。当材料在上料斗中充电时，其中一个充气阀打开，波纹管是无压力的。在此期间，或之后不久，充电，上料斗旋转。对于下料斗期间，上料斗的阀关闭，波纹管充气，上料斗料斗关闭，波纹管膨胀，上闸阀加压。
