FIELD: process engineering.
SUBSTANCE: invention relates to duct flushing reversing adapter and may be used in public water supply systems. Adapter consists of case with water feed hole at its rear and set of rear nozzles. Said rear nozzles are directed toward water feed bore. Besides, proposed device comprises set of front nozzles arranged at case front and directed from water feed bores. Mechanism of reversing said nozzle comprises slide valve with inner water line, spring, balls, front and rear toothed crowns. Front crown has shot and long grooves for balls alternating in circle. Adapter case front part comprises extra set of nozzles directed to water feed bore and communicated with the set of front nozzles. Note here that rear nozzles have total area of outlets s and inclination to adapter axis α. Extra front nozzles have total area of outlets s1 and inclination to adapter axis α1. Front nozzle have total area of outlets s2 and inclination α2. Relationship between area of nozzle outlets and inclination is defined by the formula 0 ≤ (s2 cos α2 - s1 cosα1/s cosα ≤ 0.3.
EFFECT: higher efficiency of washing away obstacles.
