Abstract
A hatch and valve arrangement for a charging installation for a shaft furnace, such as a blast furnace, said arrangement comprising a housing (1), inside which is located at least one hatch (21) and/or a valve (31), caused to pivot by an actuator (25, 35) located outside the housing and connected to the hatch or valve by a linking shaft guided in a bearing that is fixed with respect to the housing. The bearing (24, 34) and the actuator (25, 35) are mounted on a detachable door (26, 36) that seals an opening (13, 15) made in the wall of the housing (1) and whose dimensions are determined such that the hatch or the valve can be withdrawn transversely to the axis of the housing through said opening.
