TEST BENCH FOR PIPELINE VALVES OF WAFER DESIGN Russian patent published in 2016 - IPC G01M3/08 

FIELD: test equipment.

SUBSTANCE: invention relates to testing equipment in machine building, and can also be used in power engineering, chemical and oil and gas industries at enterprises producing inspection and repair of pipeline valves. Test bench comprises fixed 1 and moving 2 faceplates, centering elements 3, a power drive of the fixed faceplate, a test pressure source, two plugs 4 of branch pipes of the pipeline valves. Each plug 4 comprises case 5 with cylindrical recess 6 made on the outer side, on which there is removable annular disc 7 with the use of sealing elastically deformable ring 8. Disc 7 has blind holes 10, outer radial groove 11 with elastically deformable ring 12 and is fixed by threaded stops 9. In case 5 there are channels 13 for supply and drainage of testing fluid and air drainage, as well as there are upper and lower extension bars in the form of squares 14 and replaceable threaded unions 15. On the open ends of annular discs 7 there are at least three guide conical pins 16.

EFFECT: technical result is creation of a test bench with expanded functional capabilities when testing different typical sizes and shapes of internal surfaces of branch pipes of pipeline valves, as well as simplified design and reduced metal consumption for plugs of the bench.
