Method for increasing safety in the CCR closed tube circuits, at quick changes of depth and in emergency situations, using clean gases, and also oxygen feeding system, without limiting the working depth

摘要

the object of the application is to increase safety in closed system way nurkowych ccr, rapid changes in depth and in emergency situations.also the dose oxygen without reducing the depth of work.this method is characterized by the fact that we have two tracks or more, one for oxygen, the second for inert gas, another for the inert gas, or other mixtures.
