FINE BUBBLE GENERATING UNIT AND WATER SUPPLY SYSTEM
To provide a fine bubble generating unit capable of generating a large amount of fine bubbles.SOLUTION: A fine bubble generation unit 100 for converting dissolved gas into bubbles by applying changes in pressure to liquid includes a tubular member 1 including a liquid flow path 4 extending along a central axis 2, and an insertion member 30 disposed in the liquid flow path. The inner wall of the tubular member has an upstream cylindrical region 7 and a downstream cylindrical region 8 which are separately positioned on the upstream and the downstream with respect to a flow direction 5 of the liquid flow path, and an upstream inner screw 12 and a downstream inner screw 15 are formed in the respective regions. The insertion member is provided with, on the circumference, an external screw in which a screw groove to engage an upstream screw groove 16 of the upstream internal screw is formed, and a flow passage extending in the direction of the central axis and penetrating the insertion member. The external screw is disposed in the upstream cylindrical region in engagement with the upstream internal thread. A restriction portion is provided between the upstream cylindrical region and the downstream cylindrical region to prevent the insertion member from moving to the downstream cylindrical region.SELECTED DRAWING: Figure 1
【課題】ファインバブルを大量に発生できるファインバブル発生ユニットを提供する。【解決手段】液体に圧力の変化を与えることによって溶存気体を気泡化するファインバブル生成ユニット１００は、中心軸２に沿って延在する液体流路４とを含む管状部材１と、液体流路の中に配置された挿入部材３０を含む。管状部材の内壁は、液体流路の流れ方向５に関して上流側と下流側に分かれて位置する上流側円筒領域７と下流側円筒領域８とを有し、それぞれの領域に上流側内ねじ１２と下流側内ねじ１５とが形成されている。挿入部材は、円周上に上流側内ねじの上流側ねじ溝１６に噛み合うねじ溝が形成された外ねじと、中心軸の方向に延在して挿入部材を貫通する流路を備えている。外ねじは上流側内ねじにかみ合わせて上流側円筒領域に配置されている。上流側円筒領域と下流側円筒領域の間には、挿入部材が下流側円筒領域に移動するのを阻止する規制部を設ける。【選択図】図１
