FIG. 5 shows a front view of the on-off valve. FIG. 6 shows a view in the direction of arrow C in FIG. The on-off valve 20 is composed of a three-way valve and has a substantially cross-shaped main body 21 extending in four directions. The main body 21 has a first opening 21a and a second opening 21b opened at the ends in two adjacent directions, and the main body 21 is bent to communicate the first opening 21a and the second opening 21b. A flow path (not shown) is formed.

第１開口部２１ａには室外機の内部に配された冷媒管から成る配管３１がロウ付等により接続される。第２開口部２１ｂには室内機から延伸される配管３２が第２開口部２１ｂに螺設したフレアナット２３により接続される。   A pipe 31 made of a refrigerant pipe disposed inside the outdoor unit is connected to the first opening 21a by brazing or the like. A pipe 32 extending from the indoor unit is connected to the second opening 21b by a flare nut 23 screwed into the second opening 21b.

本体部２１の外面には対向する二方向に突出するフランジ部２２が設けられる。フランジ部２２の一面の設置面２２ａが室外機の鉛直に配された側板等に設けられる被取付部１９に当接し、フランジ部２２を貫通するネジ３３が被取付部１９に螺合される。これにより、開閉弁２０が被取付部１９に取り付けられる。   A flange portion 22 is provided on the outer surface of the main body portion 21 so as to protrude in two opposite directions. An installation surface 22 a on one surface of the flange portion 22 abuts on the attached portion 19 provided on a side plate or the like arranged vertically in the outdoor unit, and a screw 33 penetrating the flange portion 22 is screwed to the attached portion 19. Thereby, the on-off valve 20 is attached to the attached portion 19.

第１開口部２１ａはフランジ部２２の設置面２２ａから図中、下方に突出して設けられる。第２開口部２１ｂはフランジ部２２の図中、上方に配され、右方に向かって開口する。   The first opening 21a is provided so as to protrude downward from the installation surface 22a of the flange 22 in the drawing. The 2nd opening part 21b is distribute | arranged upwards in the figure of the flange part 22, and opens toward the right side.

本体部２１の内部には第１開口部２１ａと第２開口部２１ｂとの間の流路を開閉する可動体（不図示）が設けられる。可動体は第１開口部２１ａに対向する第３開口部（不図示）から挿入され、第３開口部はキャップ２４を螺設して塞がれる。本体部２１の第２開口部２１ｂに対向する位置には真空引きを行うサービスポート（不図示）が開口し、キャップ２５を螺設して塞がれる。   A movable body (not shown) that opens and closes the flow path between the first opening 21 a and the second opening 21 b is provided inside the main body 21. The movable body is inserted from a third opening (not shown) facing the first opening 21a, and the third opening is closed by screwing a cap 24.

しかしながら、上記従来の開閉弁２０によると、工具３５によりフレアナット２３が強固に締付けられるため、フランジ部２２の図中、上方の本体部２１がフランジ部２２に対して傾倒する。これにより、本体部２１内に歪みが生じて流路を閉じる位置に配された可動体と本体部２１内の流路の内壁との間に隙間が形成され、冷媒漏れが発生する。このため、別のスパナ等の工具３６により本体部２１を支持しながら工具３５によりフレアナット２３の締付けを行う二丁掛けによって配管３２を接続して冷媒漏れが防止される。従って、開閉弁２０の配管接続時に２つの工具３５、３６を必要とし、作業性が悪い問題があった。   However, according to the conventional on-off valve 20, the flare nut 23 is firmly tightened by the tool 35, so that the upper body portion 21 in the drawing of the flange portion 22 is tilted with respect to the flange portion 22. As a result, a gap is formed between the movable body arranged at a position where the main body 21 is distorted and the flow path is closed and the inner wall of the flow path in the main body 21, and refrigerant leakage occurs. For this reason, the piping 32 is connected by two hooks that tighten the flare nut 23 with the tool 35 while supporting the main body portion 21 with another tool 36 such as a wrench to prevent leakage of the refrigerant. Therefore, the two tools 35 and 36 are required when the on-off valve 20 is connected to the pipe, and there is a problem that workability is poor.
