Abstract

Circumferentially-sectioned valve cages are disclosed. An example apparatus comprises a plurality of cage sections collectively configured to be removably coupled together to form a valve cage having a circumference and a plurality of joints. The joints correspond in number to the cage sections and are spaced apart from one another about the circumference. Respective ones of the joints are defined by neighboring ones of the cage sections.

First claim

What is claimed is:

1. An apparatus, comprising:
a plurality of cage sections collectively configured to be removably coupled together to form a valve cage having a circumference and a plurality of joints, each cage section of the plurality of cage sections including a plurality of openings extending through a sidewall of the cage section, the plurality of joints corresponding in number to the plurality of cage sections, respective ones of the plurality of joints being spaced apart from one another about the circumference, respective ones of the plurality of joints being defined by neighboring ones of the plurality of cage sections.

2. The apparatus of claim 1 , wherein each joint of the plurality of joints extends in an axial direction defined by a central axis of the valve cage.

3. The apparatus of claim 1 , wherein respective ones of the plurality of cage sections have corresponding arc lengths, and wherein respective ones of the corresponding arc lengths are equal to one another.

4. The apparatus of claim 1 , wherein the plurality of the cage sections includes a first cage section, a second cage section, and a third cage section, the first cage section configured to be removably coupled to the second and third cage sections, the second cage section configured to be removably coupled to the first and third cage sections, the third cage section configured to be removably coupled to the first and second cage sections.

5. The apparatus of claim 1 , wherein the plurality of the cage sections includes a first cage section and a second cage section, the first cage section including a first arm extending circumferentially away from an end of the first cage section, the first arm having a first axially-oriented opening, the second cage section including a second arm extending circumferentially away from an end of the second cage section, the second arm having a second axially-oriented opening, the second arm configured to be interleaved with the first arm, the second axially-oriented opening configured to align with the first axially-oriented opening, the aligned first and second axially-oriented openings configured to receive a pin, the pin configured to removably couple the first cage section to the second cage section.

6. The apparatus of claim 1 , wherein the plurality of the cage sections includes a first cage section and a second cage section, the first cage section including a first sidewall and a first flange extending outwardly from the first sidewall, the first flange having a first transversely-oriented opening, the second cage section including a second sidewall and a second flange extending outwardly from the second sidewall, the second flange having a second transversely-oriented opening configured to align with the first transversely-oriented opening, the aligned first and second transversely-oriented openings configured to receive a bolt, the bolt configured to removably couple the first cage section to the second cage section.

7. The apparatus of claim 1 , wherein the plurality of the cage sections includes a first cage section and a second cage section, the first cage section including a tab extending circumferentially away from an end of the first cage section, the second cage section including a blank recessed circumferentially into an end of the second cage section, the blank configured to axially receive the tab to form an interlocked tab-and-blank connection, the interlocked tab-and-blank connection configured to removably couple the first cage section to the second cage section.

8. The apparatus of claim 1 , wherein the plurality of the cage sections includes a first cage section and a second cage section, the first cage section including a tongue extending circumferentially away from an end of the first cage section, the second cage section including a groove recessed circumferentially into an end of the second cage section, the groove configured to receive the tongue to form a frictional tongue-and-groove connection, the frictional tongue-and-groove connection configured to removably couple the first cage section to the second cage section.

9. A valve cage, comprising:
a plurality of cage sections removably coupled together to form a circumference of the valve cage, each cage section of the plurality of cage sections including a plurality of openings extending through a sidewall of the cage section; and
a plurality of joints, the plurality of joints corresponding in number to the plurality of cage sections, respective ones of the plurality of joints being spaced apart from one another about the circumference, respective ones of the plurality of joints being defined by neighboring ones of the plurality of cage sections.

10. The valve cage of claim 9 , wherein each joint of the plurality of joints extends in an axial direction defined by a central axis of the valve cage.

11. The valve cage of claim 9 , wherein respective ones of the plurality of cage sections have corresponding arc lengths, and wherein respective ones of the corresponding arc lengths are equal to one another.

12. The valve cage of claim 9 , further comprising a pin, wherein the plurality of the cage sections includes a first cage section and a second cage section, the first cage section including a first arm extending circumferentially away from an end of the first cage section, the first arm having a first axially-oriented opening, the second cage section including a second arm extending circumferentially away from an end of the second cage section, the second arm having a second axially-oriented opening, the second arm interleaved with the first arm, the second axially-oriented opening aligned with the first axially-oriented opening, the pin being disposed in the first and second axially-oriented openings, the pin removably coupling the first cage section to the second cage section.

13. The valve cage of claim 9 , further comprising a bolt, wherein the plurality of the cage sections includes a first cage section and a second cage section, the first cage section including a first sidewall and a first flange extending outwardly from the first sidewall, the first flange having a first transversely-oriented opening, the second cage section including a second sidewall and a second flange extending outwardly from the second sidewall, the second flange having a second transversely-oriented opening aligned with the first transversely-oriented opening, the bolt being disposed in the first and second transversely-oriented openings, the bolt removably coupling the first cage section to the second cage section.

14. The valve cage of claim 9 , further comprising an interlocked tab-and-blank connection, wherein the plurality of the cage sections includes a first cage section and a second cage section, the first cage section including a tab extending circumferentially away from an end of the first cage section, the second cage section including a blank recessed circumferentially into an end of the second cage section, the blank axially receiving the tab to form the interlocked tab-and-blank connection, the interlocked tab-and-blank connection removably coupling the first cage section to the second cage section.

15. The valve cage of claim 9 , further comprising a frictional tongue-and-groove connection, wherein the plurality of the cage sections includes a first cage section and a second cage section, the first cage section including a tongue extending circumferentially away from an end of the first cage section, the second cage section including a groove recessed circumferentially into an end of the second cage section, the groove receiving the tongue to form the fr
