AXIAL CONTROL VALVE Russian patent published in 2020 - IPC F16K1/12 F16K3/24 F16K47/14 

FIELD: machine building.

SUBSTANCE: present invention relates to valve industry. Axial control valve comprises external and internal housings, inlet and outlet flanges, flow divider, which is a perforated cylinder, coaxial to which there is a locking member, connected to the rack-type drive by means of a rod, an expansion bushing placed in the outlet flange. Locking element is installed with possibility of rotation around its axis. End section of the rod is installed in the cavity of the internal housing by means of a bearing. Holes in the perforated cylinder are rectangular openings, smaller sides of which have the same size and are parallel to the longitudinal axis of the perforated cylinder, length of larger sides decreases in rows from outlet branch pipe to inner housing, at that smaller sides at one end are located along one line. Holes in the locking element have the shape of isosceles triangles, the bases of which are equal in length and are arranged parallel to the smaller sides of the rectangular windows in the respective rows.

EFFECT: proposed design of axial control valve allows providing high accuracy of flow rate control in wide range.
