PURPOSE:To simplify the fitting work by a method wherein a structure of a coupling part of an inner and outer connecting auxiliary piping is made as free fitting and removable, and the connecting of an inner and outer piping can be made only with a torque wrench by fixing the coupling part to a part of a main body. CONSTITUTION:A main body partition plate 9 which forms a part of a partition plate 5 is provided with guide parts 10 for an inner and outer connecting auxiliary piping, notches 12 following the hexagon shape of a coupling part, and a swivel lock member 13 which serves for both stopping of swiveling and reinforcing of the notches 12 at the clamping and forms a part of the hexagon shape of the coupling part. A supporting member 14 for fixing a piping is fixed with screw parts 16, 17 after inserted into a cut standing part 15 of the main body partition plate 9. In some cases, the coupling part can be clamped with pressing thereof to the swivel lock member 13 without using of the supporting member 14. Accordingly, at the clamping of the inner and outer connecting piping, the coupling part is fixed, further, the leading of the piping can be performed freely by the removing of a fixing member. |
