PROTECTIVE MEMBER FOR VENT VALVE, VENT VALVE DEVICE AND PIPING STRUCTURE
To provide the protective member for the vent valve, that prevents dirt from adhering to the vent valve from the inside of a piping material without hindering inflow of outside air as much as possible.SOLUTION: The protection member 150 comprises a louver part 153 that is disposed closer to an axial deep part side of a tubular part than the vent valve 100 so as to at least partially cover the vent valve 100 from the axial deep part side. The louver part 153 has a plurality of annular blade bodies 153a arranged concentrically and spaced apart from each other. A ventilation path that allows the inflow of air from the vent valve 100 to the piping material is formed between adjacent blade bodies 153a.SELECTED DRAWING: Figure 1
【課題】外気の流入を極力妨げずに、通気弁への配管材内部からの汚れの付着を防止する通気弁用の保護部材を提供する。【解決手段】保護部材１５０は、通気弁１００を軸方向深部側から少なくとも部分的に覆うように通気弁１００よりも筒部の軸方向深部側に配置されるルーバー部１５３を備える。ルーバー部１５３は、同心円状に互いに離隔するように配列した複数の環状の羽根体１５３ａを備える。隣接する羽根体１５３ａの間には、通気弁１００から配管材への空気の流入を許容する通気路が形成される。【選択図】図１
