Abstract
A flow stabilizer adapted to be disposed in an outlet passage of a rotary valve includes a main body having an axis, a first end, and a second end. A first shell is disposed at least partially within the main body, and the first shell includes an axis, a first end, and a second end. A second shell is disposed at least partially within the main body and at least partially within the first shell, and the second shell includes an axis, a first end, and a second end. The axis of the first shell is angled relative to the axis of the main body and the axis of the second shell is angled relative to axis of the main body.
Claims20
A control valve comprising:
- a valve body including a generally axial fluid flow path extending from an upstream face surface to a downstream face surface of the valve body, the valve body having a chamber and a control member disposed within the chamber to control fluid flow through the valve body;
- and
- a flow stabilizer disposed adjacent to the downstream face surface of the valve body, the flow stabilizer including plurality of nested shells and including:
- an outer shell having an outer shell axis, a first end, and a second end;
- and
- a first inner shell disposed at least partially within the outer shell, the first inner shell having an axis, a first end, and a second end, and
- wherein the axis of the first inner shell is angled relative to the axis of the outer shell.
A flow stabilizer adapted to be disposed in an outlet passage of a control valve, the flow stabilizer comprising:
- a main body having a main body axis, a first end, and a second end;
- a first shell disposed at least partially within the main body, the first shell having an axis, a first end, and a second end;
- wherein the axis of the first shell is angled relative to the axis of the main body.
A flow stabilizer adapted to be disposed in an outlet passage of a control valve, the flow stabilizer comprising:
- a main body extending having an axis, a first end, and a second end;
- a first shell disposed at least partially within the main body, the first shell having an axis, a first end, and a second end;
- and
- a second shell disposed at least partially within the main body and at least partially within the first shell, the second shell having an axis, a first end, and a second end;
- a first brace integrally formed with the main body and the first shell;
- a second brace integrally formed with the first shell and the second shell;
- wherein a cross-sectional shape of the first shell is circular from the first end of the first shell to the second end of the first shell,
- wherein a cross-sectional shape of the second shell is circular from the first end of the second shell to the second end of the second shell.
