BALL VALVE WITH FILTER AND PRESSURE REDUCER Russian patent published in 2013 - IPC F16K5/06 G05D16/10 B01D35/04 

FIELD: machine building.

SUBSTANCE: ball valve with a filter and a pressure reducer includes housing 1 with inlet 2 and outlet 3 coupling branch pipes, which are located on one axis on opposite sides, filtration chamber 5 located radially relative to the axis of the above branch pipes and chamber 6 of the reducer. Clear opening of the cavity of housing 1 between branch pipes 2, 3 is covered with division wall 16. Filtration chamber 5 has annular centring element 18 adjacent to one end part 17 of filtering element 11. Plug 10 is fixed in filtration chamber 5 and provided with annular centring element 20 adjacent to the second end part 21 of filtering element 11. Ball gate 7 has guide opening 23 and is installed in housing 1 between dividing cross connection 16 and inlet coupling branch pipe 2 with possibility of being turned manually. Chamber 6 of the reducer is provided with cylindrical cavity 31 interconnected with cavity 32 of outlet branch pipe 3 through opening 33 and covered with cover plate 14. Stock 12 of the reducer has piston section 34 on one end and fixed plate 13 of the reducer on the other one, has open axial seat 35 interconnected with radial opening 36 in stock 12. In housing 1 there is seat 38 with central opening 39 for fitting of plate 13. Annular cavity 30 is interconnected through outlet channel 40 to cavity 32 through opening 39. Stock 12 of the reducer is located on the side of cover plate 14 with a gap interconnected with the cavity of seat 35. In cylindrical cavity 31 between its bottom 43 and piston section 34 there is spring 15.

EFFECT: enlarging the number of pipeline parts of shutoff and water purifying valves, which implement compactly in a single housing the assemblies performing the functions of pipeline shutdown, filtration and regulation of pressure of the transported medium with high reliability degree.
