Abstract

A valve including a housing, a body having an aperture radially therethrough fluidly connecting a volume radially inwardly of the body with a volume radially outwardly of the body, a bulkhead sealedly disposed between the body and the housing, the bulkhead having a port therein, a piston extending through the bulkhead and sealed thereto, the piston having a bias end and a carrier end, a biasing member connected to the bias end of the piston, the piston exposed at a carrier end to fluid pressure from the volume radially inwardly of the body, a port closure operably connected to the piston.

First claim

What is claimed is:

1. A valve comprising:
a housing;
a body having an aperture radially therethrough fluidly connecting a volume radially inwardly of the body with a volume radially outwardly of the body;
a bulkhead sealedly disposed between the body and the housing, the bulkhead having a port therein;
a piston extending through the bulkhead and sealed thereto, the piston having a bias end and a carrier end;
a biasing member connected to the bias end of the piston, the piston exposed at a carrier end to fluid pressure from the volume radially inwardly of the body;
a port closure operably connected to the piston.

2. The valve as claimed in claim 1 wherein the port or the port closure includes a seal interactive with the other of the port or the port closure in selected positions of the valve.

3. The valve as claimed in claim 1 wherein the port closure is a pin.

4. The valve as claimed in claim 1 wherein the bias end of the piston is configured to be exposed to fluid pressure segregated from the fluid pressure from the volume radially inwardly of the body such that in the event of a differential pressure experienced across the bulkhead during use, the piston will move.

5. The valve as claimed in claim 1 further comprising a piston carrier attached to the one end of the piston.

6. The valve as claimed in claim 5 wherein the piston carrier supports the port closure.

7. The valve as claimed in claim 5 wherein the piston carrier is rotatably engaged with the piston.

8. The valve as claimed in claim 7 wherein the rotatability of the piston carrier relative to the piston effects alignment or misalignment of the port closure with the port in the bulkhead to protect the port closure from erosion when the port is open.

9. The valve as claimed in claim 1 wherein the biasing member is a spring follower and a compression spring biased against piston movement pursuant to actuation.

10. The valve as claimed in claim 9 wherein the actuation is application of pressure.

11. The valve as claimed in claim 9 wherein the actuation is via shifting tool.

12. The valve as claimed in claim 1 further comprising a J-slot mechanism operably connected to the piston.

13. The valve as claimed in claim 12 wherein the operable connection between the j-slot and the piston is through a pin follower engaged with the j-slot and engaged with a piston carrier attached to the piston.

14. The valve as claimed in claim 13 wherein the piston carrier includes a slot receptive to the pin follower to allow pin movement while navigating the j-slot and for piston carrier rotation when the pin moves to one end of the slot.

15. The valve as claimed in claim 1 further comprising a key interactive with the piston and extending through the aperture and configured to be engagable with a shifting tool to actuate the valve mechanically.

16. The valve as claimed in claim 1 wherein the body is as-rolled pipe.
