TEST BENCH FOR TIGHTNESS OF PIPELINE FITTINGS OF OUTBOARD DESIGN Russian patent published in 2024 - IPC G01M3/08 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, in particular, to testing equipment and can be used for testing of hydraulic actuated pipeline valves for tightness in production conditions. Device comprises frame with fixed and movable plates, pump unit, pipelines and pressure gauges. Fixed and movable plates are located in parallel, one above the other and have a stud joint to each other. Stud joint consists of at least four studs, the screwed ends of which are screwed into the fixed plate, and the nut ends are inserted into the movable plate. At the same time in the centre of the inner surface of each of the plates there are recesses for installation of adapters with the help of fasteners. Besides, this device comprises second pump unit to feed compensating pressure via feed pipeline into drain chamber of tested article hydraulic drive. Pump unit providing pressure of medium through supply pipeline is connected to flow part of tested article. There is also an outlet pipeline and pressure gauges installed on supply pipelines.

EFFECT: possibility of reducing loads on tested product during tests, as well as testing of products with minimum weight and size characteristics, during design of which there is no excess safety margin.
