Abstract

A valve actuating assembly is provided that comprises a cam holder positioned within a valve body of an internal valve, a cam operably coupled to the cam holder and configured to engage a valve stem of the internal valve for moving the internal valve between a first position and a second position, and an actuating shaft extending through at least a portion of the valve body, rotation of the actuating shaft causing rotation of the cam holder and the cam, wherein the actuating shaft is removably coupled to the cam holder such that the actuating shaft can be decoupled from the cam holder and removed from the valve body, the cam holder and the cam being configured to remain positioned within the valve body when the actuating shaft is decoupled from the cam holder and removed from the valve body.

First claim

What is claimed is:

1. A valve actuating assembly for actuating an internal valve between a closed position and an open position, the valve actuating assembly comprising:
a cam holder stem securely connected to a valve body of the internal valve;
a cam holder having a first end and a second end, the first end of the cam holder operably coupled to a portion of the cam holder stem to position the cam holder within the valve body of the internal valve;
a cam operably mounted to the cam holder; and
an actuating shaft extending through at least a portion of the valve body of the internal valve, the actuating shaft removably coupled to the second end of the cam holder such that the actuating shaft can be decoupled from the cam holder and removed from the valve body,
wherein the cam holder and the cam are configured to remain connected to the cam holder stem and remain positioned within the valve body when the actuating shaft is decoupled from the cam holder and removed from the valve body.

2. The valve actuating assembly of claim 1 , wherein the actuating shaft comprises a cam holder connection portion having a non-circular shape configured to removably couple the actuating shaft to a corresponding bore formed in the second end of the cam holder.

3. The valve actuating assembly of claim 1 , further comprising a retaining ring configured to operably hold the cam to the cam holder, wherein the cam holder comprises a retaining ring groove defined in an outer surface of the cam holder and configured to receive the retaining ring.

4. The valve actuating assembly of claim 1 , wherein the cam holder stem is configured to support the cam holder and the cam within the valve body when the actuating shaft is decoupled from the cam holder and removed from the valve body.

5. The valve actuating assembly of claim 1 , further comprising a locking ring configured to operably attach the cam holder stem to the cam holder, wherein the cam holder stem comprises a locking ring groove defined in an outer surface of the cam holder stem and configured to receive the locking ring.

6. The valve actuating assembly of claim 1 , further comprising a plurality of pins coupled to holes extending through an outer surface of the cam holder, the plurality of pins being configured to operably secure the cam holder to the cam holder stem.

7. The valve actuating assembly of claim 1 , wherein the cam includes a non-circular bore configured to receive a non-circular end of the cam holder.

8. The valve actuating assembly of claim 7 , wherein the non-circular end of the cam holder includes a non-circular opening for receiving a cam holder connection portion of the actuating shaft.

9. The valve actuating assembly of claim 1 , wherein the cam holder stem comprises: a first end operably coupled to the first end of the cam holder, and a second end threadably engaged to the valve body to secure the cam holder stem to the valve body.

10. A valve actuating assembly for actuating an internal valve between a first position and a second position, the valve actuating assembly comprising:
a cam holder positioned within a valve body of the internal valve;
a cam operably coupled to the cam holder and configured to engage a valve stem of the internal valve for moving the internal valve between the first position and the second position; and
an actuating shaft extending through at least a portion of the valve body of the internal valve, rotation of the actuating shaft causing rotation of the cam holder and the cam,
wherein the actuating shaft is removably coupled to the cam holder such that the actuating shaft can be decoupled from the cam holder and removed from the valve body, and
wherein the cam holder and the cam are configured to remain positioned within the valve body of the internal valve when the actuating shaft is decoupled from the cam holder and removed from the valve body.

11. The valve actuating assembly of claim 10 , wherein the actuating shaft comprises a cam holder connection portion having a non-circular shape configured to removably couple the actuating shaft to a corresponding bore formed in the cam holder.

12. The valve actuating assembly of claim 10 , further comprising a retaining ring configured to operably hold the cam to the cam holder, wherein the cam holder comprises a retaining ring groove defined in an outer surface of the cam holder and configured to receive the retaining ring.

13. The valve actuating assembly of claim 10 , further comprising a cam holder stem operatively coupled to the cam holder and the valve body, wherein the cam holder stem is configured to support the cam holder and the cam within the valve body when the actuating shaft is decoupled from the cam holder and removed from the valve body of the internal valve.

14. The valve actuating assembly of claim 13 , further comprising a locking ring configured to operably attach the cam holder stem to the cam holder, wherein the cam holder stem comprises a locking ring groove defined in an outer surface of the cam holder stem and configured to receive the locking ring.

15. The valve actuating assembly of claim 13 , further comprising a plurality of pins coupled to holes extending through an outer surface of the cam holder, the plurality of pins being configured to operably secure the cam holder to the cam holder stem.

16. The valve actuating assembly of claim 13 , wherein the cam holder stem comprises: a first end operably coupled to a first end of the cam holder, and a second end threadably engaged to the valve body of the internal valve to secure the cam holder stem to the valve body.

17. The valve actuating assembly of claim 10 , wherein the cam includes a non-circular bore configured to receive a non-circular end of the cam holder.

18. The valve actuating assembly of claim 17 , wherein the non-circular end of the cam holder includes a non-circular opening configured to receive a cam holder connection portion of the actuating shaft.

19. An internal valve for conveying fluid, the internal valve having a closed position and an open position, the internal valve comprising:
a valve body comprising a plurality of inner surfaces that define a passage through the valve body, a valve seat disposed adjacent an inlet of the passage, a valve stem, and a poppet connected to and moveable with the valve stem between a first position in which the poppet sealingly engages the valve seat and a second position in which the poppet is disengaged from the valve seat; and
a valve actuating assembly operatively engaged to the valve stem to move the valve stem and the poppet between the first position and the second position, the valve actuating assembly comprising:
a cam holder positioned in the passage of the valve body,
a cam operably coupled to the cam holder and engaged with the valve stem,
an actuating shaft extending through a portion of the passage and removably coupled to the cam holder, and
a cam holder stem configured to securely couple the cam holder to the valve body,
wherein rotation of the actuating shaft causes a rotation of the cam holder and the cam to cause the valve stem and the poppet to move between the first position and the second position, and
wherein the cam holder and the cam remain positioned in the passage and engaged to the valve stem when the actuating shaft is decoupled from the cam holder and removed from the portion of the passage.

20. The internal valve of claim 19 , wherein the cam holder stem is configured to support the cam holder and the cam within the valve body
