Gas filling plant for containers

摘要

The plant comprises a set of feed gas sources (18,20), a network of controlled valves (12), selectively linking the outlet o each feed gas source to the cylinders, and a unit (16) for driving the network of valves and adapted so as to control the state the valves. The drive unit (16) comprises an input device (60) for entering a recipe consisting of a sequence of procedures, eac procedure describing an elementary task which can be implemented by the valves under the control of the drive unit (16). It furthermore comprises a device (62) for processing the successive procedures constituting the recipe. They are adapted to contro the network of valves (12) by the sequential implementation of the elementary tasks described successively in the sequence of procedures.
