Abstract
A control valve has a trim assembly to condition the flow of fluid through the control valve and, in some applications, to provide guidance for a valve plug. The trim assembly has a lattice structure formed of a plurality of triply periodic surfaces that form a plurality of passages that extend between an inner surface of the circumferential wall and an outer surface of the circumferential wall.
Claims21
A control valve, comprising:
- a body having an inlet and an outlet;
- a valve seat positioned in a passageway of the body between the inlet and the outlet;
- a valve plug positioned within the body and movable between a closed position, in which the valve plug sealingly engages the valve seat, and an open position, in which the valve plug is spaced away from the valve seat;
- and
- a trim assembly disposed within the body adjacent the valve seat and proximate the valve plug to provide guidance for the valve plug and to condition a flow of fluid through the control valve, the trim assembly comprising a circumferential wall having a lattice structure formed of a plurality of triply periodic surfaces, the lattice structure having a plurality of passages that extend between an inner surface of the circumferential wall and an outer surface of the circumferential wall.

A cage for a control valve, the cage comprising:
- a circumferential wall having a lattice structure formed of a plurality of triply periodic surfaces, the lattice structure having a plurality of passages that extend between an inner surface of the circumferential wall and an outer surface of the circumferential wall;
- wherein
- the cage is disposed within a body of the control valve adjacent a valve seat and proximate a valve plug to provide guidance for the valve plug and to condition a flow of fluid through the control valve.
A control valve, comprising:
- a body having an inlet and an outlet;
- a valve seat positioned in a passageway of the body between the inlet and the outlet;
- a fluid control member positioned within the body and movable between a closed position and an open position;
- and
- a means for conditioning a flow of fluid through the control valve, the means for conditioning comprising a lattice structure formed of a plurality of triply periodic surfaces, the lattice structure having a plurality of passages that extend between a first surface of the lattice structure and a second surface of the lattice structure, opposite the first surface.
