Kind Code:
A
Abstract:
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
