Abstract
Apparatus for noise reduction in valves are disclosed herein. An example valve disclosed herein includes a valve body defining a fluid passageway between an inlet and an outlet, a plug, and a cage in the fluid passageway. The plug is disposed in the cage. The plug is moveable in the cage to control fluid flow through the fluid passageway. The cage includes an inner wall having first openings, an outer wall having second openings, the outer wall disposed coaxially around the inner wall, and an insert having third openings. The insert is disposed between the inner wall and the outer wall.
Claims19
A valve comprising:
- a valve body defining a fluid passageway between an inlet and an outlet;
- a plug;
- and
- a cage in the fluid passageway, the plug disposed in the cage, the plug moveable in the cage to control fluid flow through the fluid passageway, the cage including:
- an inner wall having first passages extending between an inner surface and an outer surface of the inner wall, the first passages having a constant diameter;
- an outer wall having second passages extending between an inner surface and an outer surface of the outer wall, the second passages having a constant diameter, the outer wall disposed coaxially around the inner wall;
- and
- an insert disposed between the inner wall and the outer wall, the insert having a lattice structure in the shape of a cylinder, the lattice structure having interconnected cells forming third passages extending between an inner surface and an outer surface of the insert, the third passages having a maximum diameter that is less than a minimum diameter of the first passages and less than a minimum diameter of the second passages.
5 more elements
A cage to be disposed in a fluid passageway of a valve, the cage comprising:
- an inner wall having first openings;
- an outer wall having second openings, the outer wall disposed coaxially around the inner wall;
- an end wall coupled between the inner wall and the outer wall such that the inner wall, the outer wall, and the end wall form a single component removable from or insertable into the valve, and such that a cavity is formed between the inner wall, the outer wall, and the end wall;
- and
- a removeable insert disposed in the cavity between the inner wall and the outer wall, the insert coaxial with the inner wall and the outer wall, the insert having a lattice structure forming third openings through the insert.
2 more elements
A method comprising:
- inserting an insert into a cavity defined between an inner wall and an outer wall of a cage, the inner wall, the outer wall, and the insert being coaxial, the inner wall having first passages extending between an inner surface and an outer surface of the inner wall, the first passages having a constant diameter, the outer wall having second passages extending between an inner surface and an outer surface of the outer wall, the second passages having a constant diameter, the insert including a lattice structure in the shape of a cylinder, the lattice structure defining third passages extending between an inner surface and an outer surface of the insert, the third passages having a maximum diameter that is less than a minimum diameter of the first passages and less than a minimum diameter of the second passages;
- and
- installing the cage in a valve body of a valve.
A valve comprising:
- a valve body defining a fluid passageway between an inlet and an outlet;
- a plug;
- and
- a cage in the fluid passageway, the plug disposed in the cage, the plug moveable in the cage to control fluid flow through the fluid passageway, the cage including:
- an inner wall having first openings;
- an outer wall having second openings, the outer wall disposed coaxially around the inner wall;
- an insert disposed between the inner wall and the outer wall, the insert having a lattice structure in the shape of a cylinder, the lattice structure having interconnected cells forming third openings;
- and
- a retainer coupled to the inner and outer walls, the retainer engaged with an end of the insert to constrain the insert in a cavity formed between the inner and outer walls, wherein the retainer has a flange extending into the cavity, the end of the insert engaged with the flange.
