DEVICE FOR MEASUREMENT OF AXIAL LOADS ACTING ON PIPELINE VALVES DURING HYDRAULIC TESTS FOR STRENGTH, DENSITY OF MATERIAL AND TIGHTNESS OF GATE VALVE

摘要

FIELD: machine building.;SUBSTANCE: invention relates to machine building, particularly, to testing equipment for pipeline fittings. Proposed device comprises bench for hydraulic tests, tested pipeline fittings and plugs. One of plugs is made composite and contains base with tensometric sensors installed in it, annular element with seals and central insert with seal connected with base.;EFFECT: high accuracy of determining actual axial loads on pipeline valves in hydraulic tests for strength, density of material and tightness of the gate.;6 cl, 1 dwg
