VALVE DEVICE USED WHEN RENEWING DRAIN VERTICAL PIPE AND RENEWAL METHOD FOR DRAIN VERTICAL PIPE
To provide a valve device that does not cause damage to a residence in a lower layer even if it is inadvertently drained, and a method for renewing a drain vertical valve.SOLUTION: A valve device comprises: a first coupling attached to the lower end of an upper drain vertical pipe, in which the drain vertical pipe is divided into an upper drain vertical pipe located above and a lower drain vertical pipe located below, respectively, for renewal of the lower drain vertical pipe with a new one so as to store wastewater that flows into the upper drain vertical pipe; a valve section consisting of an openable and closable valve arranged below the first coupling and a second coupling for attaching to the upper end of the new lower drain vertical pipe; a hose section to be detachably attached to the second fitting in the valve section; and a tank section attached to the hose section to store the wastewater that flows into the upper drain vertical pipe. The wastewater that flows into the upper drain vertical pipe is stored in the tank section via the valve section, the hose section, and the tank section.SELECTED DRAWING: Figure 1
【課題】 うっかり排水をしたとしても、下層の住居内に被害が及ばないバルブ装置と、排水立管を更新する排水立管更新工法を提供する。【解決手段】排水立管を、上方に配置された上方排水立管と下方に配置された下方排水立管と、にそれぞれ分割し、前記下方排水立管を新規な下方排水立管に更新するために、前記上方排水立管に流入した排水を貯留するため、前記上方排水立管の下端部に取り付ける第１継手と、第１継手の下方に配置する開閉可能なバルブと、新規な下方排水立管の上端部に取り付けるための第２継手と、を具備するバルブ部と、バルブ部における第２継手と取り外し可能に取り付けるホース部と、ホース部に取り付けられ、前記上方排水立管に流入した排水を貯留するタンク部と、を有し、上方排水立管に流入した排水は、前記バルブ部と、前記ホース部と、を介して前記タンク部に貯留するバルブ装置である。【選択図】 図１
