          下密封組合:下密封組合分為料流調節閥和下密封閥,其結構與上密封組合相同,只是料流調節閥外部驅動方式為伺服電機。料流調節閥的作用是通過調整菱形閥瓣的開度(γ角)來調節向高爐布料的速度和料流量,從而與溜槽的傾角(α角)和旋轉(β角)同步配合,達到符合要求的布料方式.

          料流調節閥和下密封閥均設有位置傳感器信號源,料流調節閥檢測信號由絕對值編碼器檢測并反饋.

          Lower Sealing Combination: The lower sealing combination is made up of burden flow regulating valve and lower sealing valve. It has the same structure with upper sealing combination, except that the exterior drive of burden flow regulating valve is servo motor. The function of burden flow regulating valve is to regulate the speed and burden flow volume of distribution of blast furnace through adjusting the opening of diamond valve petal (γangel), so as to cooperate synchronously with tilting(αangel) and rotation(βangel)of the chute to meet the applicable distributing mode.

          The signal sources of position senor tare equipped on burden flow regulating valve and lower sealing valve, and the testing signal of burden flow regulating valve is tested and fed back by absolute value coder.
