Brief description of the detection of leaks of gas cylinders and an installation for filling bottles of gas a detection of leaks

摘要

Gas bottles arrive on platform (1) and are positioned (3) on axis (ZZ). A bell (6) covers the head of the bottle and after air rinsing (10,62) further air and any gas is passed through a valve (19) to an infrared absorption analyzer (141). Finally the valve is opened and a pressure depression draws the remaining air and gas through the analyzer. An electronic unit (142) interprets the results and signals a module (5) which controls the subsequent bottle path.
