STRAIGHT-FLOW VALVE Russian patent published in 2019 - IPC F16K1/12 F16K1/54 

FIELD: valve industry.

SUBSTANCE: present invention relates to valves, in particular to axial flow control valves used in industrial pipe fittings, and is intended to regulate and shut off fluids and liquids. Direct-flow valve containing external and internal housings, inlet and outlet branch pipes with flanges, flow divider made in form of perforated hollow cylinder, holes in which are arranged in circular rows, locking device with translational motion drive, locking device, external surface of shell is made in the form of two parts cylindrical and curvilinear, at that, cylindrical part is in contact with inner housing surface. On the inner surface of the perforated hollow cylinder, between annular rows of holes, annular rows of flat plates of trapezoidal shape are installed, inclined to the valve axis, wherein the height and inclination angle of the flat plates increase in the rows from the inner housing to the outlet branch pipe, and the number of flat plates in the rows is equal to the number of holes in the rows of the perforated hollow cylinder.

EFFECT: disclosed straight-flow valve significantly unload the locking device, reduces loads on the drive and reduces turbulence.
