PROBLEM TO BE SOLVED: To provide a piping system that can reduce a quantity of piping components constituting a conduit to simplify the conduit by making an opening/closing part of a flow path compact and simplifying an internal structure, and facilitating the assembling and maintenance of a conduit, and having high operability and high sealing performance while exhibiting excellent flow amount characteristics, and to provide a joining member and a rotary valve.SOLUTION: A piping system includes a pipe 20 and a joint body 21 of a one-piece structure having at least two inlets/outlets for joining the pipe 20. The joint body 21 includes at least one opening orthogonal to a flow path. A sealing member and a rotary operation part are assembled to a valve body having a through-hole to constitute a valve unit 25. The valve unit 25 is assembled in the joint body 21 through the opening to dispose an inlet/outlet to be openable/closable. |
