<p>PROBLEM TO BE SOLVED: To reduce influence to the occupying area of a secondary tube and minimize the mechanical part getting into contact with a raw fluid and also minimize a preventive seal of leackage. SOLUTION: This double-flow charging valve is provided with a passage for a raw material, a primary charging tube 38 partitioning the inside stream zone, another passage for the raw material, a secondary charging tube 40 inserted at least partly into the inside stream zone of the primary charging tube 38, and a valve plug 66 adjusting the connection of the fluid between the inside stream zones of the primary and secondary charging tubes 28, 40. A plurality of kinds of fluid are mixed together by manipulating an actuator 58 arranged at the outside of the stream zone of the secondary charging tube 40, in order to transfer the valve plug 66.</p> |
