FLAW DETECTOR-PROJECTILE FOR INTRATUBAL INVESTIGATION OF PIPELINES

摘要

FIELD: measurement equipment.;SUBSTANCE: invention is related to design of flaw detector - projectile used for inspection of gas line condition. Flaw detector - projectile for intratubal investigation of pipelines moved by flow of transported gas comprises front and back fairings for reduction of frontal resistance of flaw detector to gas flow and board electronics with system of flaw detector motion speed, comprising two adjusting elements - device for closure of internal opening of flaw detector - projectile, arranged in the form of six pairwise opposite rotary sectors, which create disk in closed position, and braking system, which represents wheels-generators with controlled active load (generator-resistive system).;EFFECT: provision of stabilisation of motion speed of intratubal inspection projectile-flaw detectors.;4 dwg
