FIELD: machine building.
SUBSTANCE: group of inventions relates to valve system, in particular, to valve system including valve seat with fine-tooth part directing flow in circumferential direction. Valve system comprises valve seat, discharge channel and shutoff valve. Valve seat has fine-tooth part having annular cavity and multiple teeth separated by multiple circular gaps. At least one of teeth has inclined surface located between one of circular spaces and appropriate tooth at angle to axis extending radially from valve seat central axis. Outlet channel is located at flow direction, behind valve seat and serves for flow outlet from valve unit. Shutoff valve is located in fine-tooth part annular cavity.
EFFECT: higher reliability and wear resistance of valve system.
