Embodiment Construction

[0048] Referring now to the specific embodiments of the drawings, Figure 2-Figure 4B Methods and apparatus for fabricating a regulator body or valve body by one or more of additive manufacturing (AM), laser sintering, stereolithography, and / or industrial three-dimensional printing are shown.

[0049] see now figure 2 , the body 112 for a fluid regulator or control valve may be fabricated at least in part by AM. The body 112 may replace the body 12 of the fluid regulator 10 or the body of the control valve in FIG. 1 . Body 112 includes an inner wall 136 including a region 138 surrounding fluid inlet 120, which may include a first flange, a region 140 surrounding fluid outlet 122, which may include a second flange, and defining a fluid flow passage connecting inlet 120 and outlet 122. 118 in area 142 . The inner wall 136 includes a region 143 surrounding a cylindrical bore 144 sized to accommodate the control rod and control elements. Inner wall 136 may include a region 146...

Abstract

A method of manufacturing a body of a fluid control device using additive manufacturing, the method comprising: forming an inner wall having an outer surface and an inner surface, a region surrounding an inlet, a region surrounding an outlet, and a region surrounding a fluid flow path, wherein the inner wall A fluid boundary is provided and connects the inlet and the outlet. The method further includes: forming a portion of the inner wall to receive a valve seat; forming a portion of the inner wall to receive a control rod and a control element; forming a lattice structure by depositing a settable material onto the inner wall in a predetermined pattern , wherein the lattice structure is three-dimensional and includes a plurality of connected lattice components.

Description

technical field [0001] The present disclosure relates to fabricating the body of a fluid regulator or control valve, and more particularly, to fabricating the body using additive manufacturing. Background technique [0002] Conventional manufacturing processes and techniques used to manufacture body assemblies of fluid regulators and control valves impose design and material constraints on the body assemblies. Die casting or similar suitable methods face certain hurdles in the manufacture of body components, and these hurdles are usually resolved at the expense of the design of the body component. For example, with regard to the ideal shape and thickness of the body, the designer of the valve body encounters the problem of making the molten metal flow in the casting. In order to solve the problems inherent in die casting, designers are limited to body designs that can be manufactured practically easily using known methods. Current manufacturing methods require additional f...
