METHOD FOR LEAK-PROOFNESS TEST AND TEST CHAMBER FOR TEST OF VESSEL LEAK- PROOFNESS

摘要

FIELD: test equipment. SUBSTANCE: the vessel is placed in a hermetically closed test chamber. A pressure differential is built up from the vessel interior to the space between the vessel exterior and the part of the test chamber wall, which results in curving out of the flexible section of the vessel wall. It is prevented by the protuberances on the test chamber wall, which support the flexible section of the vessel wall. Due to the presence of recesses between the protuberances, the built-up pressure in the space between the exterior of the vessel wall and the wall of the test chamber is dissipated around the vessel and not in the recesses. EFFECT: reduced time of the test cycle and enhanced precision of measurement in the process of test of vessel leak-proofness on the test line. 6 cl, 5 dwg
