Abstract
A gas supply system for providing high pressure (HP) gas to a low pressure (LP) gas destination, having a primary HP gas unit and a reserve HP gas unit, which provide regulated lower-pressure gas to a supply manifold, and an LP destination regulator that provides an LP regulated gas supply to a consumption subsystem. A one-way flow valve in fluid communication from the primary HP gas unit to the reserve HP gas unit, ensures that the reserve HP gas unit remains substantially full, even after numerous cycles of depletion and replacement of the primary HP gas unit, during which the HP supply is provided by the reserve HP gas unit, which helps to avoid the risk that the reserve tank pressure and supply might mistakenly, unexpectedly or unintentionally be depleted.
Claims7
A system for providing high pressure (HP) gas to a low pressure (LP) gas destination, comprising:
- (i) a primary HP gas unit comprising:
- a. one or more primary cylinders containing HP gas, each primary cylinder including an outlet shutoff valve,
- b. a primary HP regulator having a gas inlet and a regulated gas outlet, the primary HP regulator configured to regulate the primary HP gas released from the one or more primary cylinders to a primary low pressure (LP) supply gas at a primary regulated pressure P1, and
- c. a primary HP manifold connected in fluid communication between the outlet of the shutoff valve of each one or more primary cylinders, and the gas inlet of the primary HP regulator;
- (ii) a reserve HP gas unit comprising:
- a. one or more reserve cylinders containing HP gas, each reserve cylinder including an outlet shutoff valve,
- b. a reserve HP regulator having a gas inlet and a regulated gas outlet, the reserve HP regulator configured to regulate the reserve HP gas released from the one or more reserve cylinders to a reserve LP supply gas at a reserve regulated pressure P2 that is less than the primary regulated pressure P1, and
- c. a reserve HP manifold connected in fluid communication between the outlet of the shutoff valve of each one or more reserve cylinders, and the gas inlet of the reserve HP regulator;
- (iii) a supply manifold connected in fluid communication to the regulated gas outlet of the primary HP regulator, and the regulated gas outlet of the reserve HP regulator;
- (iv) an LP supply regulator having a gas inlet in fluid communication with the supply manifold, and a regulated gas outlet in fluid communication with a usage gas consumption system, the LP supply regulator configured to regulate the primary LP supply gas or the reserve LP supply gas to a usage pressure P3 that is less than primary regulated pressure P1 and reserve regulated pressure P2;
- and
- (v) a one-way flow valve having an inlet in fluid communication with the primary HP manifold, and an outlet in fluid communication with the reserve HP manifold.
A HP gas supply system, comprising:
- (i) one or more primary cylinders containing HP gas, each primary cylinder including an outlet shutoff valve,
- (ii) a primary HP manifold connected in fluid communication to the outlet shutoff valve of each one or more primary cylinders, and to a separate, low-pressure gas subsystem,
- (iii) one or more reserve cylinders containing HP gas, each reserve cylinder including an outlet shutoff valve,
- (iv) a reserve HP manifold connected in fluid communication to the outlet shutoff valve of each one or more reserve cylinders, and to the low-pressure gas subsystem, and
- (v) a one-way flow valve having an inlet in fluid communication with the primary HP manifold, and an outlet in fluid communication with the reserve HP manifold.
