CONDUIT SWITCHING APPARATUS

PURPOSE:To improve sealing performance and simplify handling by arranging a plurality of outlet pipes onto a rack along the locus drawn by an elevation pipe through the turn of a connecting pipe, permitting the connection with the elevation pipe. CONSTITUTION:Three outlet pipes 41-43 are arranged at the fan-shaped part 3 of a rack along the locus drawn by an elevation pipe 35 through the turn of a connecting pipe 7, permitting the connection with the elevation pipe 35. When the elevation pipe 35 is raised by driving a motor 38 until a valve piece 25 contacts with a valve seat 12, the fluid on the upstream side is cut-off at the outlet 11 of the connecting pipe 7. When, the connecting pipe 7 is turned by driving a motor 29, and the elevation pipe 35 is lowered by driving the motor 38 until the undersurface of the elevation pipe 35 contacts with the gaskets 47 of the outlet pipes 41-43, fluid flows into the outlet pipes 41-43 from the gap formed between the valve piece 25 and the valve seat 12.
