VALVE DEVICE AND PIPING STRUCTURE
To provide a valve device capable of selectively closing a drain path by a valve element, and efficiently discharging flowing water to a downstream side in opening the valve element.SOLUTION: A valve device 100 includes: a device main body 110 composed of a cylindrical peripheral wall 111 and including an upstream-side opening end 112 formed on one end of the peripheral wall 111, a downstream-side opening end 113 formed on the other end of the peripheral wall 111, a fluid flow channel formed between the upstream-side opening end 112 and the downstream-side opening end 113, and a valve seat 114 disposed on the way of the flow channel inside of the peripheral wall 111; a valve element 130 disposed on the flow channel inside of the peripheral wall 111 and displaced to a closing position to close the flow channel by sitting on the valve seat 114, and an opening position to open the flow channel by separating from the valve seat 114 to allow drain water to flow from the upstream-side opening end 112 to the downstream-side opening end 113; and an air valve 140 formed on the valve element 130 and allowing the air at the downstream side to move to the upstream side.SELECTED DRAWING: Figure 23
【課題】排水経路を弁体によって選択的に閉鎖可能であるとともに、弁体の開放時に流水をより効率的に下流に排水することを可能とする、弁装置を提供する。【解決手段】弁装置１００は、筒状の周壁１１１からなり、周壁１１１の一端に形成された上流側開口端１１２、周壁１１１の他端に形成された下流側開口端１１３、上流側開口端１１２と下流側開口端１１３との間に形成された流体の流路、及び、周壁１１１内部の流路の途中に配置された弁座１１４を備える装置本体１１０と、周壁１１１内部の流路上に配置され、弁座１１４に着座して流路を閉鎖する閉鎖位置と、排水が上流側開口端１１２から下流側開口端１１３へと流れることを許容すべく、弁座１１４から離隔して流路を開放する開放位置とに変位する弁体１３０と、弁体１３０に形成され、下流側の空気が上流側へ移動することを許容する空気弁１４０と、を備える。【選択図】図２３
