Abstract
An air eliminator including a housing having first and second portions, the housing defining: a chamber, an inlet in fluid communication with the chamber; an outlet in fluid communication with the chamber; and an axis extending from the first portion to the second portion, a float assembly connected to the first portion of the chamber for releasing air from the chamber, and degassing disks stacked within the chamber along an axis, wherein each disk includes a plurality of rings such that the degassing disks cause micro gas pockets in water passing through the chamber to combine into relatively large and buoyant air pockets that collect and pass along the axis to the float assembly for release.
Claims19
An air eliminator comprising:
- a housing having first and second portions, the housing defining:
- a chamber, an inlet in fluid communication with the chamber;
- an outlet in fluid communication with the chamber;
- and an axis extending from the first portion to the second portion;
- a float assembly connected to the first portion of the chamber for releasing air from the chamber;
- and
- degassing disks stacked within the chamber along the axis, wherein each disk includes a plurality of rings such that the degassing disks cause micro gas pockets in water passing through the chamber to combine into relatively large and buoyant air pockets that collect and pass along the axis to the float assembly for release.
An air eliminator comprising:
- a housing having first and second portions, the housing defining:
- a chamber, an inlet in fluid communication with the chamber;
- an outlet in fluid communication with the chamber;
- and an axis extending from the first portion to the second portion;
- a float assembly connected to the first portion of the chamber for releasing air from the chamber;
- and
- means for causing micro gas pockets in water passing through the chamber to combine into relatively large and buoyant air pockets that collect and pass along the axis to the float assembly for release,
- wherein the means for causing micro gas pockets includes a plurality of components with a central hub, spokes extending radially outwardly from the central hub, and vertical spacers extending from a plurality of the spokes, and each component defines at least one key and socket for aligning and interlocking with an adjacent component.
An air eliminator comprising:
- a housing having first and second portions, the housing defining:
- a chamber, an inlet in fluid communication with the chamber;
- an outlet in fluid communication with the chamber;
- and an axis extending from the first portion to the second portion;
- a float assembly connected to the first portion of the chamber for releasing air from the chamber, the float assembly including a tubular body extending along the axis out of the housing, a cap sealing the tubular body, the cap having a first normally open vent and a second vent, a poppet valve seated in the second vent, a float within the tubular body, an arm having a first end pivotally connected to the cap and a second end pivotally connected to the float, and a plug secured to the arm such that when fluid in the chamber causes the float to move along the axis towards the first portion, the plug blocks the first vent to prevent air from exiting the chamber there through;
- and
- means for causing micro gas pockets in water passing through the chamber to combine into relatively large and buoyant air pockets that collect and pass along the axis to the float assembly for release,
- wherein the means for causing micro gas pockets includes a plurality of components with a central hub, spokes extending radially outwardly from the central hub, and vertical spacers extending from a plurality of the spokes, and each component defines at least one key and socket for aligning and interlocking with an adjacent component.
