Abstract
Methods, apparatus, and systems for valve trim apparatus for use with control valves are disclosed. An example apparatus includes a valve body including a fluid flow path between an inlet and an outlet. The example apparatus also includes valve trim positioned in the fluid flow path, the valve trim including a first passageway extending from the inlet to the outlet, the first passageway including a first pressure staged passage and a second pressure staged passage, the second pressure staged passage including a first radial passageway.
Claims18
An apparatus comprising:
- a valve body including a fluid flow path between an inlet and an outlet;
- and
- valve trim positioned in the fluid flow path, the valve trim including a first passageway extending from the inlet to the outlet, the first passageway including a first pressure staged passage and a second pressure staged passage, the second pressure staged passage including a first radial passageway, the first pressure staged passage fluidly coupled to the second pressure staged passage via a first throat, the first pressure staged passage has a hexagonal cross-section and the first throat has a circular cross-section.
An apparatus comprising:
- a valve body including a fluid flow path between an inlet and an outlet;
- and
- valve trim positioned in the fluid flow path, the valve trim including a first passageway extending from the inlet to the outlet, the first passageway including a first pressure staged passage and a second pressure staged passage, the second pressure staged passage including a first radial passageway, the first radial passageway formed in a portion of the first passageway adjacent a second passageway, the second passageway extending from the inlet to the outlet, the first radial passageway to fluidly couple the first passageway to the second passageway, the first passageway including a third pressure staged passage, the second pressure staged passage is fluidly coupled to the third pressure staged passage via a second throat.
An apparatus comprising:
- valve trim including fluid passageways extending from a first end to a second end, the fluid passageways including respective pressure staged passages that extend along the valve trim, the valve trim having a first diameter proximate the first end to accommodate a first number of the fluid passageways and a second diameter proximate the second end to increase the number of the fluid passageways to greater than the first number.
An apparatus comprising:
- a valve body including a fluid flow path between an inlet and an outlet;
- and
- valve trim positioned in the fluid flow path, the valve trim including a first passageway extending from the inlet to the outlet, the first passageway including a first pressure staged passage and a second pressure staged passage, the second pressure staged passage including a first radial passageway, the valve trim includes a first diameter proximate the inlet and a second diameter proximate the outlet, the second diameter larger than the first diameter.
