摘要

FIELD: machine building.;SUBSTANCE: invention relates to anti-acing systems of aircrafts. System (30) of bleed air pressure control for aircraft anti-icing system comprises first upstream pressure control valve (32) and second downstream pressure control valve (34) arranged in series in air flow path (28). Each of valves (32, 34) has pressure control chamber (74) in fluid communication with corresponding pressure setting valve (82, 84), each of which is in fluid communication with inlet (88, 96) of bleed air upstream from first pressure control valve (32). First pressure control valve (32) is installed to control pressure of bleed air up to the first pressure, and the second downstream control pressure valve (34) is installed for regulation of bleed air pressure to the second pressure which is higher than the first pressure.;EFFECT: invention improves serviceability in case of valve failure.;15 cl, 2 dwg
