JOINT WITH VENT VALVE
PROBLEM TO BE SOLVED: To provide a joint with a vent valve that can be easily assembled into a drain path.SOLUTION: A recess part 53 is formed at a connecting margin 52 for a trap end part T1 of a first connection port 5 of a main pipe part 2 constituting a drain passage D at a joint 1 with a vent valve assembled into the drain passage D. When the main pipe part 2 is turned along a direction extending along the drain passage D and inserted into a cutting location L while a connecting margin 61 of a second connecting port 6 is applying over a drain pipe end part P1, a contact between the connecting margin 52 and the trap end part T1 is avoided by the recess part 53, so that it becomes possible to insert the main pipe part 2 smoothly to the cutting location L and it is possible to assemble easily the joint 1 with the vent valve to the drain passage D.SELECTED DRAWING: Figure 5
【課題】排水経路に容易に組み込むことのできる通気弁付継手を提供する。【解決手段】排水経路Ｄに組み込まれる通気弁付継手１における、排水経路Ｄを構成する本管部２の第一接続口５のトラップ端部Ｔ１への接続代５２に凹部５３を形成することで、第二接続口６の接続代６１を排水管端部Ｐ１に覆いかぶせつつ本管部２を排水経路Ｄに沿う方向に回動させて分断箇所Ｌに差し入れる際に、凹部５３によって接続代５２とトラップ端部Ｔ１との接触が避けらるので、本管部２が分断箇所Ｌに円滑に差し入れ可能となり、通気弁付継手１を容易に排水経路Ｄに組み込むことができる。【選択図】 図５
