AXIAL CONTROL VALVE Russian patent published in 2018 - IPC F16K1/12 F16K47/02 

FIELD: valves production.

SUBSTANCE: invention relates to the valve assembly, in particular to the axial flow control valves used in industrial pipeline fittings, and is intended for controlling and closing the working fluids and gases. Axial control valve contains external and internal bodies, inlet and outlet branch pipe stubs with flanges, flow divider in the form of a perforated hollow cylinder, locking device with a translational drive in the form of a rack mechanism. Holes in the perforated hollow cylinder are arranged in circular rows, have an elliptical shape, the semimajor axis of the ellipse being inclined to the longitudinal axis of the valve at an angle that is the same in each row and increasing from row to row along the fluid flow.

EFFECT: offered axial control valve has a relatively simple structure that allows to reduce cavitation effects and increase the service life.
