DEVICE FOR TESTING HYDRAULIC PIPELINE flanged valves for strength, density and tightness

摘要

1. A device for testing the hydraulic valves on the pipeline flange strength, density and tightness, comprising a table with the sealing member and the duct for supplying the test fluid in the cavity of the test fixture, the cap with the sealing member and the mechanism of its pressing to the flange sealing surface of the main test valve, wherein that the device is provided with an additional cap with a channel for feeding the medium into the cavity of the test fixture connected to the table plate, with centering conductive protrusion on the work surface, an outer diameter smaller than the inner diameter of the main pipe test fixture for a guaranteed clearance between the annular nimi.2. The apparatus according to claim. 1, characterized in that the centering lug on the plug is in the form stakana.3. The apparatus according to claim 2, characterized in that the portion of the outer surface of the glass, adjacent to its edge, formed in the shape of a truncated cone, the smaller base facing towards kromke.4. An apparatus according to any one of claims 2 and 3, characterized in that the wall of the cup but formed around the perimeter of slit from the edge to the flat surface of its cap parallel to its obrazuyuschim.5. The apparatus according to claim 1, characterized in that the mating surface of the table plate is provided with a stub concentrically disposed cylindrical projection, and the table plate holds the corresponding blind hole.
