BALL SHUTTER ASSEMBLY WITH BUILT-IN VALVE Russian patent published in 2020 - IPC F16K5/06 F16K1/02 F16K11/18 

FIELD: valve industry.

SUBSTANCE: invention relates to heating, water supply and gas supply systems for buildings and structures. Ball valve 3 with diametrical hole 4 is installed in channel 2 of housing 1 with possibility of rotation. Rod bushing 7 is installed in housing 1 with output from housing 1 to the outside and is conjugated by second end 10 with ball gate 3 with possibility of rotation of ball gate 3. Rod 12 is installed in the hole of rod bushing 7 with outward output from rod bushing 7 of first end 14, as well as with passage through radial hole 6 of ball gate 3 of second end 15 of rod 12. Rod 12 is provided with means 16 to apply torque to its first end 14. Pipeline valve element 17 to control flow through diametrical hole 4 of ball gate 3 is fixed on second end 15 of rod 12. Separator 18 is fixed in diametrical hole 4 of ball gate 3 and is made with middle section 19 with hole 20 located geometrically along axis of rod 12, as well as with two overlapping sections 21, 22 located on opposite sides of middle section 19 and made with each possibility of overlapping half of diametrical hole 4, one overlapping section 21 – along radial direction of diametrical hole 4 towards radial hole 6 of ball gate 3, and by second 22 – in opposite radial direction of diametrical hole 4. Stem 12 and rod bushing 7 are made with mating along thread 23 for their relative longitudinal displacement at their relative turn. Pipeline valve element 17 is made round and is arranged to interface with middle section 19 of separator 18 along perimeter of hole 20 made in this middle section 19.

EFFECT: invention is aimed at provision of smooth proportional control, mainly manually, of liquid or gas flow through ball valve.
