Abstract

A receptacle for conveying fluid is disclosed. The receptacle may include a main body, a spring retainer, a valve seat assembly, a poppet, and a spring. The main body defines an inlet and an outlet. The spring retainer is disposed in the main body and removable from the main body via the inlet. The valve seat assembly is disposed in the main body and removable from the main body via the inlet. The poppet is slidably engaged with the spring retainer between a closed position and an open position and is engageable with the valve seat assembly. The spring is engaged with the spring retainer and with the poppet to urge the poppet against the valve seat assembly.

First claim

What is claimed is:

1. A receptacle comprising:
a main body defining an inlet and an outlet;
a spring retainer disposed in the main body and removable from the main body via the inlet;
a valve seat assembly disposed in the main body and removable from the main body via the inlet, wherein the valve seat assembly comprises:
a seat disc disposed in a valve seat, wherein the valve seat comprises a body, a first annular extension extending axially away from the body, and a second annular extension extending axially away from the body, wherein the second annular extension is concentrically disposed in the first annular extension, wherein the body, the first annular extension, and the second annular extension define an annular pocket, and wherein the seat disc is disposed in the annular pocket; and
a seat ring engaged with the valve seat to retain the seat disc;

a poppet slidably engaged with the spring retainer between a closed position and an open position and engageable with the valve seat assembly, wherein the poppet contacts the seat disc in the closed position; and
a spring engaged with the spring retainer and with the poppet to urge the poppet against the valve seat assembly.

2. The receptacle of claim 1 , wherein
the seat ring is externally threaded;
the first annular extension is internally threaded to threadably receive the seat ring; and
the seat disc is captured by the seat ring, the body, and the second annular extension.

3. The receptacle of claim 1 , wherein the valve seat assembly is configured to receive a tool to engage the valve seat assembly with the main body and to remove the valve seat assembly from the main body.

4. The receptacle of claim 1 , wherein
when the valve seat assembly is engaged with the main body, the spring retainer is captured between the spring and the main body; and
when the valve seat assembly is removed from the main body, the spring retainer slides freely out of the main body.

5. A receptacle comprising:
a main body defining an inlet and an outlet;
a spring retainer disposed in the main body and removable from the main body via the inlet;
a valve seat assembly disposed in the main body and removable from the main body via the inlet, wherein the valve seat assembly comprises:
a seat disc disposed in a valve seat, wherein the valve seat comprises a body, a sealing flange extending radially outwardly from the body, and a sealing lip extending axially away from the sealing flange, and wherein the body, the sealing flange, and the sealing lip define an annular channel; and
a seat ring engaged with the valve seat to retain the seat disc;

a poppet slidably engaged with the spring retainer between a closed position and an open position and engageable with the valve seat assembly, wherein the poppet contacts the seat disc in the closed position; and
a spring engaged with the spring retainer and with the poppet to urge the poppet against the valve seat assembly.

6. The receptacle of claim 5 , wherein the sealing lip contacts the main body to seal the valve seat to the main body.

7. A receptacle comprising:
a main body configured to convey fluid and including an inner step having a first inner diameter and a seating surface having a second inner diameter greater than the first inner diameter;
a spring retainer removably disposed in the main body to abut the inner step;
a valve seat assembly removably engaged with the main body to abut the seating surface, wherein the valve seat assembly comprises:
a seat disc disposed in a valve seat, wherein the valve seat comprises a body, a sealing flange extending radially outwardly from the body, and a sealing lip extending axially away from the sealing flange, and wherein the body, the sealing flange, and the sealing lip define an annular channel; and
a seat ring engaged with the valve seat to retain the seat disc;

a poppet slidably engaged with the spring retainer between an open position and a closed position and configured to selectively engage with the valve seat assembly, wherein the poppet contacts the seat disc in the closed position; and
a spring engaged with the poppet and with the spring retainer to urge the poppet against the valve seat assembly.

8. The receptacle of claim 7 , wherein the poppet has a partially conical sealing surface to engage the seat disc in the closed position.

9. The receptacle of claim 7 , wherein the seat ring defines at least one tool pocket to receive a tool to threadably engage the seat ring with the valve seat.

10. The receptacle of claim 7 , wherein:
the spring retainer comprises a plurality of outwardly extending arms;
the plurality of arms abut the inner step; and
the plurality of arms and the main body define a corresponding plurality of passages.

11. The receptacle of claim 10 , wherein, when the poppet is pushed away from the valve seat assembly from the closed position to the open position, the fluid flows through the valve seat assembly and the plurality of passages.

12. The receptacle of claim 7 , wherein the seating surface is partially conical, the sealing lip contacts the seating surface, and the valve seat is threadably engaged with the main body.

13. The receptacle of claim 12 , wherein, when the valve seat is tightened, the sealing lip is elastically deformed to partially close the annular channel to seal the valve seat against the main body.

14. A valve seat assembly, comprising:
a valve seat comprising a first body, and inner and outer annular extensions extending axially away from the first body to define an annular pocket;
a seat disc disposed in the annular pocket and comprising a second body, a flange extending radially outwardly from the second body to define a first shoulder, and a lip extending radially inwardly from the second body to define a second shoulder, the second shoulder engaging the inner annular extension; and
a seat ring threadably engaged with the valve seat to retain the seat disc and threadably engaged in the outer annular extension to engage the first shoulder.

15. The valve seat assembly of claim 14 , wherein the valve seat defines an inner void, is configured to receive a tool in the inner void, and includes an inner ledge to prevent the tool from passing through the valve seat via the inner void.

16. A valve, comprising:
a main body;
a valve seat assembly comprising:
a valve seat comprising:
a body;
a first annular extension extending axially away from the body; and
a second annular extension extending axially away from the body and being concentrically disposed in the first annular extension, wherein the body, the first annular extension, and the second annular extension define an annular pocket;

a seat disc disposed in the annular pocket; and
a seat ring threadably engaged with the valve seat to retain the seat disc; and

a poppet configured to slide between a closed position at which the poppet is configured to engage the seat disc and an open position.

17. A valve comprising:
a main body;
a valve seat assembly comprising:
a valve seat defining an annular pocket and comprising:
a body;
a sealing flange extending radially outwardly from the body; and
a sealing lip extending axially away from the sealing flange, wherein the body, the sealing flange, and the sealing lip define an annular channel;

a seat disc disposed in the annular pocket; and
a seat ring threadably engaged with the valve seat to retain the seat disc; and

a poppet configured to slide between a closed position at which the poppet is configured to engage the seat disc and an open position
