Summary:To provide a valve body unit for communication water path capable of inhibiting a harmful effect caused by water hammering.SOLUTION: A valve body unit 4 is fitted to a communication water path 3 for supplying service water to a farm field 1 from an irrigation channel adjacent to the farm field 1. The valve body unit 4 comprises: a main body 10; a coupling part 12 coupled to a maintaining member 9 which is knocked to soil 2. The main body 10 has therein, a channel 10a communicated with an inside of the communication water path 3, and has a valve body 7 for closing and opening the channel 10a. The coupling part 12 is coupled to the maintaining member 9 knocked to the soil 2, therefore, a harmful effect such as water hammering can be suppressed, the water hammering causing detachment of the valve body unit 4 from the communication water path 3 when the valve body 7 closes the channel 10a.SELECTED DRAWING: Figure 1 【課題】 ウォーターハンマーによる弊害を抑制することができる、連絡水路用の弁体ユニットを提供する。【解決手段】 弁体ユニット4は、圃場1に隣接した用水路から圃場1へ用水を供給する連絡水路3に取り付けられる。この弁体ユニット4は、本体10と、土壌2に打ち込まれる維持部材9と結合される結合部12とを備える。本体10は、連絡水路3の内部と通じる流路10aを内部に有するとともにその流路10aを開閉する弁体7を有する。結合部12が、土壌2に打ち込まれた維持部材9と結合されることで、弁体7で流路10aを閉鎖した際のウォーターハンマーによって弁体ユニット4が連絡水路3から外れる等の弊害が、抑制される。【選択図】 図1
