Figures 1 to 6 show an embodiment of the present invention, in which Figure 1 is a vertical sectional view, Figure 2 a, b, and c are valve seats;
is a side view, b is a plan view, c is a developed view of the E-Ro part of a, Fig. 3 a and b are the valve body, a is a side view, b is a plan view, and Fig. 4 is the valve seat/valve. A cross-sectional view between the bodies showing the flow of steam. FIGS. 5a and 5b are developed views showing the relationship between the valve seat and the valve body, where a shows the state when the lift is low and FIG. 5b shows the state when the lift is high. FIG. 6 is a graph showing the area of the regulating valve and the lift. 7 and 8 are longitudinal sectional views of conventional speed regulating valves, where FIG. 7 is a double seat valve and FIG. 8 is a diffuser valve. 1: Valve seat, 2: Valve body, 3, 3-1, 3-2, 3
-3,...: Hole.
