     . . I. . .
    The invention relates to a valve and can be used to improve the unstable outflow of liquid and gaseous media in various systems. .
    The purpose of the invention is to increase the efficiency of the stabilization process by increasing the intensity of jet mixing, reducing the length of the sections of their interaction and reducing noise ...
    FIG. 1 shows a hemispherical shut-off and regulating authority and. hemispherical saddle, cuts} on. FIG. 2 shows section A-A in FIG. 1v on .fig. 3 is a variant of the shape of the recess in the valve seat, the section in FIG. 4 - valve and seat in the contact position ..
    Valve valve 1, providing stabilization of the outflow of compressible fluid or, gas under pressure drop, with intrasonic expansion, is made with a hemispherical part 2, which interacts with the bearing half-part 3 of the seat 4. It is mounted with the possibility of axial movement and it is provided with a cylindrical or truncated-conic shank 5, conjugated along curve 6 with half auster ical part 2.
    The saddle 4 is made in the form of a converging-diverging nozzle with six longitudinal notches 7 located on its inner periphery, evenly spaced around the circumference.
    The depth of the grooves is variable. Her. the maximum value is in the area 8 located below the annular zone of contact of the hemispherical part 2 of the closure body with the hemispherical part 3 of the seat, then it gradually decreases to zero in the direction of the diverging nozzle. The groove 7 is parallel to the valve axis 9, -but it can also expand downwards. Tangles of each notch with opposite walls (surfaces) of the regulating body are formed by a converging-diverging nozzle 10 with a reduced vacuum zone, the shape of which varies depending on the position of the locking regulator intermediate between the closed position and shown in FIG. I dot-dash line, and the partial opening position indicated in FIG. 1 with a solid line.
    In the embodiment illustrated in FIG. I and 2, the deposition of the notch has the shape of a slot of a rectangular cross section, and several of the slots form a sequence of grooves made around the periphery of the saddle 4 below the closure line 11;
    In the embodiment-, shown in FIG. 3, the bottom of the recess 7 forms a blunt dihedral angle, the edge 12 of which is perpendicular to the valve axis 9. The front face 13 of the dihedral angle is shorter than its rear face 14. In FIG. 4 that the rear edge of the recess 7 is rounded at point 15, immediately behind the line 11 to close. FIG. 1, wavy line 16 denotes a direct-compression shock-compression wave. The bottom surface 17 of the stem 5 of the valve is filled with a recess 18 for improving valve performance. The width of the grooves is equal to the peripheral distance between two adjacent grooves. In the position of incomplete opening of the valve, between the opposing surfaces of the valve and the seat, outside the recesses of the seat, supersonic nozzles are formed, and subsonic at the level of the recesses.
