DIRECT-FLOW 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. Straight-flow valve contains external and internal housings, inlet and outlet branch pipes with flanges, a flow divider made in the form of a perforated hollow cylinder, a locking device with a drive of translational motion in the form of a rack mechanism. Locking device is a cylinder-conical shell, the conical part of which is mounted on the side of the outlet pipe, inner surface of the shell interacting with the outer surface of the perforated hollow cylinder which is closed at one end and in the side parts with the surface of the inner shell, and on the inner surface of the shell, in the zone of its cylindrical part there are radial partitions connected to the rack mechanism.

EFFECT: proposed direct-flow valve has a relatively simple design, allows you to significantly relieve the locking device, reduce the load on the drive and reduce turbulence.
