DEVICE FOR CHECK-UP OF LEAK-PROOFNESS OF VESSELS OPERATING IN VACUUM AT LOW TEMPERATURES Russian patent published in 2001 - IPC

Abstract RU 2172479 C2

FIELD: test equipment, applicable in check-up of leak-proofness of fuel tanks of launch vehicles. SUBSTANCE: the device has a test chamber for accommodation of the vessel to be tested communicating with the liquid refrigerant feed and vent pipelines, test gas feed pipeline, level gauge, leak detector, pressure gauge, the tested vessel is enveloped from all sides by a gas-permeable cover made of adsorbent for free passage of test gas through it and precipitation of molecules of liquid re-it and precipitation of molecules of liquid refrigerant in it. The gas-permeable cover may be made of carbon cloth. EFFECT: enhanced accuracy of leak-proofness test. 2 cl, 1 dwg
