    摘要： A valve apparatus for preventing the reverse of a thrust force and the generation of oscillation by smoothing a fluid flowing, including: an upper plug and an upper sheet ring which are for adjusting flow of fluid to an upper current path; and a lower plug and a lower sheet ring which are provided on the same axis as the upper plug and the upper sheet ring, and are for adjusting flow of fluid to a lower current path, wherein the generation of oscillation noise can be prevented by making the upper flowing path and the lower flowing path as different shapes, by making the upper and lower plug shape different, by making the plug operation stable with the reverse of the thrust force being prevented by making the fluid amount for the upper flowing path being increased, with the upper and lower sheet ring being formed as one body.
