COUPLING FOR INDIRECT DRAINAGE
PROBLEM TO BE SOLVED: To provide a coupling for indirect drainage that prevents a fluid (drain water or gas) on a downstream side from leaking into an upstream side.SOLUTION: A coupling for indirect drainage 1 of this invention includes a body part 10 including a drainage space 15. A trap 50 is attached to a predetermined position in the drainage space 15 of the body part 10. A valve body 60 provided in the trap 50 converts states between a fluid passing state β that allows drain water flowing from an upstream side to pass toward a downstream side and a fluid reverse flow blocking state α that prevents a fluid in a drain pipe part 73 from flowing out to the upstream side.SELECTED DRAWING: Figure 3
【課題】下流側の流体（排水やガス）が上流側へ漏出してしまうことを防止する間接排水用継手を提供する。【解決手段】間接排水用継手１は、排水用空間１５を有する本体部１０を備え、本体部１０における排水用空間１５内の所定位置には、トラップ５０が取り付けられており、トラップ５０に備えられた弁体６０は、上流から流れてくる排水が下流に向けて通過する通過状態βと、排水管部７３内の流体が上流側へ流出することを阻止する流体逆流阻止状態αと、の間で状態変換する。【選択図】図３
