Compressed gas flow initiated and controlled automatic sequencing cascade system for the recharging of compressed gas cylinders

摘要

The Flow Indicating Switch (FIS) triggered Automatic Sequencing Cascade System and method is used to control the correct sequential discharge of compressed gas storage cylinders into one or more compressed gas cylinders(s) which are being recharged by the monitoring of compressed gas flow quantity. The primary purpose of the FIS Auto-Cascade is maximize the efficient use of the compressed gas within the storage cylinders by minimizing the possibility of to human error which will result in the overall loss of the total system recharging potential. The secondary purpose of the system use is for the ability to Auto-Cascade recharge cylinders in an area remote to the cascade storages cylinders and main valve body such as would be the case when this system is used in association with a Firefighter Breathing Air replenishment System (FBARS) for use in “tall” or “sprawling” structure such as those discussed in the International Association of Plumbing and Mechanical Officials (IAPMO) documentation. When used in the FBARS the FIS triggered Automatic Sequencing Cascade System and method is remotely triggered when Fire Suppression or Rescue personnel connect their SCBA cylinder to the FBARS recharge panel. The compressed gas flow from the cascade system into the SCBA cylinder passes through the FIS which will initial and control the correct sequential discharge of the compressed gas storage cylinders into the SCBA cylinder which is being recharged.
