INTAKE/EXHAUST VALVE
To provide an intake/exhaust valve capable of discharging water in a drain hopper even when drain water flows little by little.SOLUTION: An intake/exhaust valve 1 is arranged in an apex T of a rise pipe SP in a water supply pipe WP of a direct-coupled water supply type. The intake/exhaust valve comprises an intake/exhaust port 5 for taking in and exhausting air and draining water in the rise pipe SP, and a drain piping 6 that includes a horizontally laying piping 7 connected with the intake/exhaust port 5 and extending from the intake/exhaust port 5 in a nearly horizontal direction and a down piping 8 extending downward nearly vertically from the horizontally laying piping 7 and having an opening end 8b for opening downward. In the drain piping 6, a drain water guide part 10 for guiding the direction of drain water D is installed from at least the middle between a base end part 8a and the opening end 8b of the down piping 8 to at least the opening end 8b, and along the pipe axis direction TA of the down piping 8.SELECTED DRAWING: Figure 2
【課題】排水が少しずつ流れる場合であっても排水ホッパー内に排出できる吸排気弁を提供する。【解決手段】本発明に係る吸排気弁１は、直結給水方式の給水管ＷＰのうちの立管ＳＰの頂部Ｔに配置されるものであって、前記立管ＳＰにおける空気の吸気および排気と排水とを行う吸排気口５と、前記吸排気口５に接続され、前記吸排気口５から略水平方向に延びる横引き配管７、および前記横引き配管７から略垂直に下方に延び、開口端８ｂが下方に向けて開口している立下り配管８を含んでなるドレン配管６と、を有し、前記ドレン配管６には、前記排水Ｄの方向を導く排水ガイド部１０が、前記立下り配管８の基端部８ａから前記開口端８ｂまでの間の少なくとも途中から、少なくとも前記開口端８ｂにわたって前記立下り配管８の管軸方向ＴＡに沿って設けられている。【選択図】図２
