To provide a joint member that is attached to a drainage pipe and has a check valve that prevents the backflow of fluid from the downstream side.SOLUTION: A joint member 1 consists of: a joint body 10 with inspection port 14 on the wall; a lid 20 that closes the inspection port 14, an adapter 30 that is connected to the lid 20 and arranged in the joint body 10; and a check valve 50 attached to the adapter 30. The check valve 50 is composed of a valve body 51 which is an umbrella valve having a T-shaped cross section, including a rod-like fixed part 52 formed in the center and an annular water stop 53 formed from the downstream end of the fixed part 52 toward the outer side in the circumferential direction. Even if the check valve 50 is arranged so that the direction of the inspection port 14 is in an arbitrary direction such as upward, downward or sideward, the drainage flow path can always be closed. Further, the joint member 1 can be connected to either a horizontal pulling tube or a vertical pulling tube.SELECTED DRAWING: Figure 1
【課題】排水配管に取り付けられて、下流側からの流体の逆流を防止する逆止め弁を備えた継ぎ手部材に関し、点検口より容易に逆止め弁の着脱や清掃等を行うことが可能となる継ぎ手部材を提供する。【解決手段】継ぎ手部材１は、壁面に点検口１４を備える継ぎ手本体１０と、点検口１４を閉塞する蓋部２０と、蓋部２０と連結されて継ぎ手本体１０内に配置されるアダプター３０と、アダプター３０に取り付けられた逆止め弁５０から成る。逆止め弁５０は断面視Ｔ字状のアンブレラ弁である弁体５１から成り、中央に形成された棒状の被固定部５２と、被固定部５２の下流側端部から周方向外側に向けて形成された円環状の止水部５３を有している。逆止め弁５０は点検口１４の方向が上方や下方や側方等、任意の向きとなるように配置されていても、常に排水流路を閉塞可能である。又、継ぎ手部材１は横引き管又は縦引き管のいずれとも接続可能である。【選択図】図１
