PROBLEM TO BE SOLVED: To provide a fluid stabilization apparatus that overcomes the problem of the conventional technique in which, when a vinyl flow path is provided in the flow path, the weight of water greatly deforms a vinyl flow path and causes deterioration in flowability and some portion of fluid being left without flowing may cause a change in temperature from the temperature at the time of injection.SOLUTION: According to the present invention, a fluid stabilization apparatus comprises a mixing unit having a first input port and a second input port. The mixing unit mixes gas injected from the first input port and a liquid injected from the second input port to form a gas-liquid two-phase flow and allows the gas-liquid two-phase flow to run from the mixing unit through a flow path made of a member that can be deformed by a liquid flowing therethrough.SELECTED DRAWING: Figure 1【課題】 従来の技術では流路にビニル製流路を設けた場合、水の重みでビニル製流路が大きく変形し、流動性が悪化する。また、流動せずに取り残された流体もあるため、注水時の温度から変化してしまうというおそれもある。【解決手段】 本発明の流動安定化装置は、第1の入力口と、第2の入力口とを具備する混合部であって、前記混合部は流路に流す液体によって変形を伴う部材で構成された前記流路に前記第1の入力口から注入した気体と前記第2の入力口から注入した液体とを混合し気液二相流を形成して、前記混合部から前記気液二相流を前記流路に流すようにする。【選択図】図1
