DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now in detail to the figures of the drawings as a whole, there is seen a steam conduit 1 which comes from a non-illustrated steam generator and is led through a wall 2 of a containment of a nuclear power station. In order to form a fixed point in a leadthrough through the wall 2, a conical supporting body 3 is provided for supporting the steam conduit 1 in the leadthrough of the wall 2. Forces and moments acting on the steam conduit 1 are introduced into the wall 2 at the fixed point. A housing of a main valve 4 is connected to the steam conduit 1 at the fixed point, directly at the leadthrough, without a high-pressure pipe being interposed. Housings of satellite valves 5 to 7 are likewise connected to the housing of this main valve 4, without a high-pressure pipe being interposed. Center points of the satellite valves 5 to 7 are located on circles around a center point of the main valve 4. There may no longer be any room on the housing of the main valve 4 for additional valves which are still required. If that is the case, in the steam conduit according to the invention, at least one additional valve 8, 9 is fastened to the housing of a satellite valve 5 to 7, without a high-pressure pipe being interposed and without any support. A plurality of additional valves can also be aligned with one another to form a row and their housings can be connected to one another. In this case, a housing of a first additional valve of this row is fastened to the housing of the satellite valve 5 to 7, without a high-pressure pipe being interposed. One or more of such rows can be fastened to each satellite valve 5, 6. It is even possible for at least one supplementary valve and/or one or more rows of supplementary valves, which can be connected to one another in the same way as additional valves to be fastened to the housing of an additional valve 8, 9. The entire illustrated valve configuration makes it possible for forces and moments acting on it to be introduced into the wall 2 through the fixed point shown.
