PIPE BLOCKAGE PREVENTION MEMBER, SIPHON WATER SUPPLY DEVICE, AND SIPHON WATER SUPPLY METHOD
To provide a pipe blockage prevention member attached to a siphon water supply device in which an opening/closing portion automatically opens by sensing or being influenced by a negative pressure and sucks outside air into a pipe member, to prevent a siphon pipe (a pipe member) from being blocked in advance, when negative pressure that is strong enough to crush and block a pipe member is generated in performing a water supply work using siphon action.SOLUTION: A pipe blockage prevention member 200 is provided in a part of a pipe member 10 constituting a siphon water supply device 100. An opening/closing portion automatically opens by sensing or being influenced by a predetermined negative pressure before a moderate amount of negative pressure to block the pipe member 10 due to an increase in negative pressure inside the pipe member 10 is applied, and sucks outside air into the pipe member, to prevent the pipe member 10 from being blocked in advance.SELECTED DRAWING: Figure 1
【課題】サイフォン作用による送水作業を行う際に、管部材を押しつぶして閉塞させるほどの負圧が発生した場合に、負圧を感知又は影響を受けて自動で開閉部が開いて外気を管部材内に吸入させることによって、サイフォン管（管部材）が閉塞することを事前に防止することができるサイフォン送水装置に取り付けられている管閉塞防止部材を提供する。【解決手段】本発明の管閉塞防止部材２００は、サイフォン送水装置１００を構成する管部材１０の一部に備えられてなり、管部材１０内部の負圧の増大によって、管部材１０が閉塞するほどの大きさの負圧がかかる前の所定の負圧を感知又は影響を受けて自動で開閉部が開いて外気を管部材内に吸入させることにより、管部材１０が閉塞することを事前に防止することを特徴とする。【選択図】図１
