Apparatus for opening and closing a fluid conduit |
摘要 |
An apparatus for opening and closing a downcomer conduit through which crude blast furnace gas is delivered to a dust catcher. A frame is provided which is completely integrated with the upper part of the dust catcher enclosure and which is a prolongation of the walls of the enclosure. The frame provides a fluid-tight compartment which allows for hermetic sealing of the valve from the environment external to the conduit.
