VALVE DEVICE, INSTALLATION STRUCTURE OF VALVE DEVICE, AND FLOW RATE ADJUSTING UNIT
To provide a user-friendly valve device.SOLUTION: A valve device 4 comprises: a flow rate adjusting unit 5 installed in an irrigation channel 1; and a valve unit 9 attached to the flow rate adjusting unit 5 and facing a farm field 2 side. The flow rate adjusting unit 5 comprises: a base plate portion 6 in which a hollow cylindrical portion 6a having a through hole 6b inside is formed so as to protrude to a front side; and a closing plate 7 which is disposed on a rear side of the base plate portion 6 so as to overlap, and moves along the base plate portion 6 so as to close the through hole 6b to change a size of an opening 6c going from the through hole 6b to the rear side. The valve unit 9 is formed in a cylindrical shape having a flow channel space 9a inside. The valve unit 9 comprises: a valve body 10 changing between a closed position closing the flow channel space 9a and an open position opening the same; and a connection portion 11 connected to the hollow cylindrical portion 6a.SELECTED DRAWING: Figure 2
【課題】 使い勝手のよい弁装置を提供する。【解決手段】 弁装置４は、用水路１に設置される流量調整ユニット５と、その流量調整ユニット５に取り付けられて圃場２側を向く弁ユニット９とを備える。流量調整ユニット５は、通孔６ｂを内部に有する中空筒部６ａが表側に突出形成された基板部６と、基板部６の裏側に重合配置されるとともに通孔６ｂに塞ぎかかるように基板部６に沿って移動して通孔６ｂから裏側に臨む開口６ｃの大きさを変化させる閉塞板７とを、備える。弁ユニット９は、流路空間９ａを内部に有する筒状に形成されており、また、その弁ユニット９は、流路空間９ａを閉鎖する閉位置と開放する開位置とに変位する弁体１０と、中空筒部６ａに連結される連結部１１とを備える。【選択図】 図２
