REGULATED DIRECT-FLOW MULTIPASSAGE THROTTLE Russian patent published in 2008 - IPC F16K3/08 F16K39/04 

FIELD: invention refers to reinforcements building.

SUBSTANCE: it is assigned for overlapping and regulation of pressure and consumption of liquid and gaseous mediums, including containing abrasives, aggressive and explosion-dangerous mediums, in engineering constructions and pipelines of high pressure. Regulated direct-flow multipassage throttle has body, input and output end-butts lids, turning wheel with drive, locking-regulating discs with mutually close-fitting end-butts and passing openings. One of discs is motionlessly installed relatively to output lid and body. Other one is installed with possibility of turning together with turning wheel. Pressure main pipeline is connected with discharging cavity. This cavity is fulfilled between end-butt of output lid and end-butt of turning wheel. Main pipeline is connected with cavity fulfilled between inner but-end of turning wheel and end and but-end of motionless disc. Discs are located in inner boring of turning wheel. From side of pressure main pipeline it is fulfilled with ring step. It interacts with supporting flange of turning disc. Between und-butt of input lid and end-butt of mobile disc there is installed pushing element in the shape of spring-actuated clamping ring. Channel connecting pressure main pipeline with discharging cavity is fulfilled inside body of throttle.

EFFECT: increases operational reliability of throttle.
