Abstract
PURPOSE:To stably open or close a small bell during charging of raw materials by providing a small bell chamber pressure take-out chamber between a pressure equalizing gas introducing valve of a flow passage feeding a pressure equalizing gas to a small chamber and the small chamber, and controlling the differential pressure between bells by the pressures taken out from this and a large bell chamber pressure equalizing part. CONSTITUTION:The pressure taken out from a small bell chamber pressure take- out part 13 provided on the small bell chamber 4 side of a pressure equalizing gas introducing valve 11 of a flow passage 9 for pressure equalizing gaseous nitrogen introduction and the pressure taken out from a take-out part 14 for large bell chamber pressure directly provided in a large bell chamber 6 are inputted to an interbell differential pressure detector, whereby the differential pressure between the bells is controlled. Thereby, the introduction of the gas for the purpose of eliminating the differential pressure between the bells is accomplished surely at the charging of raw materials.
