Control valve trim assembly
First Claim
Patent Images
1. 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 that are periodic in cylindrical or spherical coordinates, 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.

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.

13. 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 that are periodic in cylindrical or spherical coordinates, 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;
whereinthe control valve is a ball valve. - View Dependent Claims (14, 15, 16, 17)
