Device for continuously circulating a liquid in order to sample or to check this liquid.

摘要

Putting the circuit under a vacuum causes liquid in the vessel (10) to rise in the feed pipe (14). The injection of compressed air from a source (28) allows the liquid to rise as far as an intermediate capacity (32). The gas is extracted by means of a pipe (36), and the degassed liquid falls by way of the pipe (34) to the sampling device (12). The invention is used for sampling radioactive liquids in the nuclear industry. <IMAGE>
