Abstract

A rotatable flange structure is provided which is integrally or monolithically formed with a Y-strainer. The rotatable flange structure can be installed over the front-mating surface of the Y-strainer. A retaining ring fits inside the grooves on the outer edge of a flange portion and on the inner edge of a mounting plate to keep the mounting plate attached to the flange portion. The flange portion can be assembled to the mounting plate and can be removed from the mounting plate in only one direction. The mounting plate may be prevented from completely being removed from the Y-strainer by an angular branch of the Y-strainer body. The retaining ring is compressed slightly by the flange portion as the rotatable mounting plate is installed to the flange portion and snaps back out into the mounting plate groove to complete the assembly and retain the mounting plate to the flange portion.

Claims

1. A plumbing component integrated with a rotatable flange apparatus, comprising:

a body portion including an angular branch and a flange portion monolithically formed with said body portion and extending from said body portion, and a fluid flow path extending through said body portion, said angular branch, and said flange portion;

said fluid flow path having an inlet through said flange portion, an outlet opposite said inlet through said body portion, and a purge through said angular branch of said body portion;

said flange portion having a face portion, a sealing surface, an outside edge and a ring groove in said outside edge;

a screen disposed within said angular branch and extending from said purge through said fluid flow path and into said fluid flow path connecting said inlet with said outlet;

a retaining ring disposable in said ring groove; and

said retaining ring having an inside diameter less than a diameter of said face portion and having an outside diameter greater than said diameter of said face portion;

a rotatable mounting plate disposed around said body portion including a hole for accepting and retaining said flange portion;

said hole having a first diameter greater than said compressed outside dimension to a first depth and a second diameter less than said ring outside diameter beyond said first depth to form a stop at said first depth, said stop preventing said face portion from passing through said hole when said ring is installed in said ring groove and allowing said face portion to pass through said hole when said ring is not installed in said ring groove.

2. The apparatus of claim 1, wherein said stop comprises a first annular groove in said hole at said first depth, said first annular groove having a diameter greater than said first diameter.

3. The apparatus of claim 1, wherein said ring groove has a semi-circular cross sectional shape and a cross sectional diameter corresponding to a cross sectional diameter of said retaining ring and providing a slip fit between said retaining ring and said ring groove.

4. The apparatus of claim 1, wherein said hole includes a lead-in chamfer from a front surface of said rotatable mounting plate to said first diameter, said chamfer having a diameter at said front surface greater than said outside diameter of said retaining ring.

5. The apparatus of claim 1, wherein said rotatable mounting plate includes at least one fastener hole extending there-through.

6. The apparatus of claim 1, wherein said rotatable mounting plate includes at least one fastener stud extending there-from.

7. The apparatus of claim 1, wherein said retaining ring is formed from a spring material and includes a ring gap allowing deformation of said ring in opposition to a spring force of said retaining ring, said deformation including compression to a compressed outside dimension of said retaining ring.

8. The apparatus of claim 7, wherein said deformation includes extension to an extended inside dimension of said retaining ring for installation to said groove.

9. The apparatus of claim 1, wherein said angular branch of said body portion is positioned at an acute angle relative to the linear plane of said outlet.

10. The apparatus of claim 1, wherein said angular branch of said body portion prevents said rotatable mounting plate from fitting over said body portion and thereby requires assembly of said rotatable mounting plate over said face portion.

11. The apparatus of claim 1, wherein said angular branch further includes a valve operably connected to said purge.

12. A method for forming a plumbing interface with a rotatable flange, comprising:

providing a Y-strainer having an integrated flange portion and a rotatable mounting plate disposed around a body portion of said Y-strainer; and

installing said rotatable mounting plate over said flange portion, said rotatable mounting plate having a hole to accept said flange portion and at least one interference portion preventing said flange portion from passing completely through said hole.

13. The method of claim 12, comprising:

installing said interference portion between said flange portion and said rotatable mounting plate before installing said rotatable mounting plate over said flange portion.

14. The method of claim 12, comprising:

aligning mounting elements in said mounting plate with corresponding mounting elements in a plumbing interface;

rotating said flange portion to a selected orientation;

locating a face of said flange portion against a mating face of said plumbing interface;

installing fasteners to said mounting elements to secure said mounting plate to said plumbing interface so that said mounting plate retains said flange portion against said plumbing interface.

15. A plumbing component integrated with a rotatable flange apparatus, comprising:

a body portion including an angular branch and a flange portion monolithically formed with said body portion and extending from said body portion, and a fluid flow path extending through said body portion, said angular branch, and said flange portion;

said fluid flow path having an inlet through said flange portion, an outlet opposite said inlet through said body portion, and a purge through said angular branch of said body portion;

said flange portion having a face portion, a sealing surface, an outside edge and a ring groove in said outside edge;

said angular branch extends from said body portion at an acute angle relative to the linear plane of said outlet;

a screen having an outer diameter disposed within said angular branch and extending from said purge through said fluid flow path and into said fluid flow path connecting said inlet with said outlet;

a cover threadably attached to said purge including a threaded aperture having an inner diameter less than said outer diameter of said screen;

a plug threadably attached to said threaded aperture of said cover;

a retaining ring disposable in said ring groove; and

said retaining ring having an outside diameter greater than said diameter of said face portion;

a rotatable mounting plate disposed around said body portion including a hole for accepting and retaining said flange portion;

said hole having a first diameter greater than said compressed outside dimension to a first depth and a second diameter less than said ring outside diameter beyond said first depth to form a stop at said first depth, said stop preventing said face portion from passing through said hole when said ring is installed in said ring groove and allowing said face portion to pass through said hole when said ring is not installed in said ring groove.

16. The apparatus of claim 15, wherein said retaining ring is formed from a spring material and includes a ring gap allowing deformation of said ring in opposition to a spring force of said retaining ring, said deformation including compression to a compressed outside dimension of said retaining ring.

17. The apparatus of claim 16, wherein said deformation includes extension to an extended inside dimension of said retaining ring for installation to said groove.

18. The apparatus of claim 17, wherein said angular branch of said body portion prevents said rotatable mounting plate from fitting over said body portion and thereby requires assembly of said rotatable mounting plate over said face portion.

19. The apparatus of claim 18, wherein said rotatable mounting plate includes at least one fastener hole extending there-through.

20. The apparatus of claim 18, wherein said rotatable mounting plate includes at least one fastener stud extending there-from.
