Abstract
Embodiments described herein relate to a pressure-regulating device, systems that include the device, and related methods. For example, the pressure-regulating device may receive gas from a gas supply at a first pressure (e.g., on a supply side of the pressure-regulating device) and may regulate or reduce the pressure of the received gas to a selected or suitable second, different pressure.
Claims21
A pressure-regulating device, comprising:
- a gas inlet;
- an expansion body defining an expansion chamber that is in fluid communication with the gas inlet, the expansion body comprising a hollow protrusion extending, from a distal wall at a distal end region of the expansion body, upstream into the expansion chamber;
- a first pressure regulation stage in fluid communication with the expansion chamber and configured to decrease gas pressure of a gas passing through the first pressure regulation stage, wherein the first pressure regulation stage includes a valve, wherein an upstream opening of the hollow protrusion located within an interior of the expansion chamber communicates gas from the interior of the expansion chamber to the valve;
- an intermediate regulator body having a proximal end region and threadedly coupled to the expansion body such that changing a distance between the distal end region of the expansion body and a proximal end region of the intermediate regulator body changes an amount of pressure decrease produced by the first pressure regulation stage;
- and
- a gas outlet positioned downstream from and in fluid communication with the first pressure regulation stage.

- an expansion body defining an expansion chamber that is in fluid communication with the gas inlet, the expansion body comprising a hollow protrusion extending, from a distal wall of the expansion body, upstream into the expansion chamber;
- a first pressure regulation stage in fluid communication with the expansion chamber and configured to decrease gas pressure of a gas passing through the first pressure regulation stage, wherein the first pressure regulation stage includes a first valve, wherein an upstream opening of the hollow protrusion located within an interior of the expansion chamber communicates gas from the interior of the expansion chamber to the valve;
- a second pressure regulation stage including a second valve arranged in series with the first valve such that gas flowing out of the first valve is communicated to an inlet of the second valve;
- and
- a gas outlet positioned downstream from and in fluid communication with the first pressure regulation stage.
3 more elements
A pressure-regulating device, comprising:
- a gas inlet;
- an expansion body defining an expansion chamber that is in fluid communication with the gas inlet;
- a first stage pressure regulator configured to decrease gas pressure of a gas flowing therethrough, the first stage pressure regulator being in fluid communication with the expansion chamber, the first stage pressure regulator including:
- a first valve including a first sealing member configured to open and close gas flow through the first valve;
- a first piston configured to move the sealing member in the manner that opens the first valve;
- and
- a first adjustment mechanism including opposing first and second threaded walls, threadedly engaged together, wherein the first piston seals against an inner surface of a first protrusion extend distally from the expansion body and offset radially inward from the first threaded wall, and wherein the first piston further seals against an inner surface of a second protrusion opposite the first protrusion and offset radially inward from the second threaded wall;
- and
- a gas outlet positioned downstream from the first stage pressure regulator.
