INDIRECT DRAINAGE JOINT
To provide a joint for indirect drainage that facilitates maintenance.SOLUTION: A joint for indirect drainage 1 is provided with a main body joint portion 15 that is provided with an outer cylindrical portion 30 provided with an outer opening 33 for taking out fluid backflow prevention means and an inner cylinder portion 50 that is provided with an inner opening portion 51 for taking out fluid backflow prevention means, is disposed within the outer cylindrical portion 30 and coaxially rotatable with respect to the outer cylinder portion 30. The inner cylinder portion 50 rotates with respect to the outer cylinder portion 30, so that the state can be freely switched between an open state γ in which the outer opening for taking out fluid backflow prevention means 33 and the inner opening portion 51 for taking out fluid backflow prevention means communicate with each other and a use state δ in which an outer water flow portion 32 and the inner opening portion 51 for taking out fluid backflow prevention means communicate with each other.SELECTED DRAWING: Figure 23
【課題】メンテナンスが容易となる間接排水用継手を提供する。【解決手段】間接排水用継手１は、流体逆流防止手段取出用外側開口部３３が設けられている外筒部３０と、流体逆流防止手段取出用内側開口部５１が設けられ外筒部３０内に配置されて当該外筒部３０に対して同軸上で回動自在とされた内筒部５０とを具備した本体継手部１５を備え、内筒部５０が外筒部３０に対して回動することで、流体逆流防止手段取出用外側開口部３３と流体逆流防止手段取出用内側開口部５１とが連通する開放状態γと、外側通水部３２と流体逆流防止手段取出用内側開口部５１とが連通した使用状態δと、の各状態に状態変換自在とされている。【選択図】図２３
