CHECK VALVE UNIT AND FAUCET DEVICE
To provide a check valve unit capable of reliably draining water inside when drainage is required, while preventing reduction in flow rate in normal use.SOLUTION: A check valve unit 20 is configured such that a primary side flow path L11, a check valve 40, and a secondary side flow path L12 are arranged substantially linearly along one axis. The check valve unit 20 comprises: a branch flow path L2 serving as a primary side pipe conduit, which is a pipe conduit branching off from the primary side flow path L11 and does not pass through the check valve 40, and a secondary side pipe conduit, which is a pipe conduit branching off from the secondary side flow path L12 and does not pass through the check valve 40; and an opening/closing screw 50 as a switching unit that switches between the open state and the closed state of the branch flow path.SELECTED DRAWING: Figure 1
【課題】通常使用時の流量低下を防ぎながら、水抜きが必要な際には確実に内部の水抜きを可能とする逆止弁ユニットを提供する。【解決手段】逆止弁ユニット２０は、一次側流路Ｌ１１、逆止弁４０、及び、二次側流路Ｌ１２が一の軸線に沿って略直線状に配置された逆止弁ユニット２０であって一次側流路Ｌ１１から分岐して逆止弁４０を経由しない管路である一次側管路、及び二次側流路Ｌ１２から分岐して逆止弁４０を経由しない管路である二次側管路としての分岐流路Ｌ２と、分岐流路の開状態と閉状態とを切り替える切替部としての開閉ネジ５０と、を含む。【選択図】図１
