JOINT MEMBER
To provide a joint member having a valve body that is attached to a drain pipe and prevents a backflow of fluid from the downstream side, which can be easily attached/detached and cleaned from an inspection port.SOLUTION: A joint member 1 includes: a joint body 10 having an inspection port 14 on a wall surface; a lid portion 20 closing the inspection port 14; an adapter 30 connected to the lid portion 20 and disposed in the joint body 10; and a check valve 50 attached to the adapter 30. The check valve 50 includes: a rod-like fixed portion 52 formed in the center; and an annular water stop portion 53 formed from the downstream end of the fixed portion 52 toward the outer side in the circumferential direction. The check valve 50 can always be provided with the water stop portion 53 at a lower end of the check valve 50, regardless of the orientation of the inspection port 14, thus preventing water from remaining in the upstream side of the check valve 50.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弁体を有する継ぎ手部材に関し、点検口より容易に弁体の着脱や清掃等を行うことが可能となる継ぎ手部材の提供を目的とする。【解決手段】継ぎ手部材１は、壁面に点検口１４を有する継ぎ手本体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から成る。逆止め弁５０は点検口１４の向きに関わらず、常に逆止め弁５０の下端に止水部５３を配置可能となるため、逆止め弁５０の上流側に水残りが生じることを防ぐことが可能となる。【選択図】図１
