[0001] This application claims priority to U.S. Serial No. 63 / 587,914, filed October 4, 2023, entitled “FABRICATING TRIM FOR A BALLVALVE”. The entire contents of this application are incorporated herein by reference. Background Technology
[0002] Flow control plays a role in many industrial facilities and systems. Ball valves are a type of flow control used in devices and networks that distribute fluids such as natural gas, steam, water, or oil. However, one problem with these devices is that the fluid may flow at a sufficiently high rate to generate vibrations as it passes through the device. If left uncontrolled, these vibrations can produce significant noise, often exceeding acceptable safety levels. Many ball valves incorporate countermeasures, including additional parts (or "spools"), designed to attenuate the flow and suppress this noise. Summary of the Invention
[0003] This disclosure relates to valve spools for suppressing noise in valves. Particular attention is paid to embodiments of methods for manufacturing valve spool parts. These embodiments are configured to reduce labor and costs in the production of throttling balls, for example, those having noise-suppressing components or devices used in ball valves. These configurations can avoid certain processes that shorten assembly time. In one specific embodiment, the manufacturer may no longer need to heat the throttling ball to install the valve spool containing the noise-suppressing features. Attached Figure Description

Detailed Implementation
[0019] The features of the embodiments shown in the above figures will now be discussed. These embodiments address manufacturers' concerns about delivery time and cost of parts that address excessive noise in ball valves or other flow control components. These parts are important because they attenuate noise from field valves to levels within the health limits of workers performing tasks in or around the equipment daily. As noted below, the embodiments significantly simplify the assembly of throttle balls or valves because they eliminate the need for manufacturers to heat or preheat the throttle balls or valves. This feature eliminates time-consuming and labor-intensive steps from the assembly process. Other embodiments are contemplated within the scope of this disclosure.
[0020] Figure 1 A perspective view depicting an example of a valve core device 100 is shown. This example includes a body 102, preferably made of machined, cast, or printed metal (such as aluminum or steel). The body 102 may be formed into an annular ring 104 having an inner surface 106 and an outer surface 108. The annular ring 104 may also have one or more openings 110, for example, through-holes penetrating or extending between surfaces 106, 108. The arrangement of the openings 110 may position these openings equidistantly from each other around the annular ring 104. Also as shown, a noise reduction element 112 may reside within the annular ring 104. This device may be integrally formed with the annular ring 104, possibly due to the fabrication of a single integral part using processes such as precision casting or additive manufacturing (“3-D printing”). This disclosure also contemplates examples where the noise reduction element 112 is, for example, a separate or independent piece secured or coupled to the inner surface 106 using welds or fasteners. In one particular embodiment, the noise reduction element 112 may include openings 114 of various geometries. The opening 114 may adopt a shape that is beneficial for noise suppression, for example, when used in a throttling ball found in a ball valve or similar device. Secondary processes on the annular ring 104 may reduce the outer diameter D to fit the interior of the throttling ball. These processes may include “turning” on a lathe or similar equipment to remove material from the outer surface 108.
[0021] Figure 2 Depicting Figure 1 A perspective view of an example of a valve core assembly 100. The body 102 may include one or more cutouts, shown herein as cutouts C1, C2 residing in diametrically opposed portions of the annular ring 104. Cutouts C1, C2 may have geometries that produce features that match features on the throttling ball. These features may include curved, arcuate, or arcuate surfaces, for example, having a radius or diameter that matches the radius or diameter on the throttling ball. In one embodiment, the features may be formed during the casting or printing of the annular ring 104. Processes such as cutting or machining may also be used to remove material from the annular ring 104 to create the necessary geometry or shape for the features.
[0022] Figure 3 Depicting Figure 1 A perspective view of an example of a valve core assembly 100. This example can be produced by a process of removing portions of the annular ring 104, preferably after turning downwards along the diameter D as indicated above. The cutting or machining may terminate the annular ring 104 at a pair of surfaces 116, shown here as spaced apart from each other by an angle α. In one embodiment, the angle α ranges between 120° and 180°, and in one example, is approximately 160°. The value of the angle α may vary according to design criteria, performance parameters, or similar requirements.
[0023] Figure 4 Depicting Figure 3 A perspective view of an example of a valve spool assembly 100. This example can be mounted inside a throttle ball 118, shown here as having a hollow interior 120. An opening 122 in the throttle ball 118 provides passage to the hollow interior 120. In one embodiment, an annular ring 104 may reside in one or more openings in the opening 122, preferably such that material flowing through the hollow interior 120 passes through an opening 114 of the noise-reducing element 112. As shown, the arcuate surface of the cut C1 may be aligned with the edge of the opening 122 of the throttle ball 118. This feature may position the material of the annular ring 104 outside the flow path to avoid potential damage or disturbance that could exacerbate noise. Welded portions 124 on one or more surfaces may secure the valve spool assembly 100 in place within the throttle ball 118.
[0024] Figure 5 Describing the available options Figure 4A perspective view of an exemplary structure of a valve 126 with a throttling ball 118. This structure may include a valve body 128, typically made of metal. The valve body 128 may be embodied as a ball valve, with the throttling ball 118 residing within a cavity 130. These types of valves may have one of several operating configurations depending on the orientation of the throttling ball 118. In one embodiment, the throttling ball 118 may have two distinct positions, such as an open position or a closed position. Other embodiments use the throttling ball 118 to reduce (or increase) the flow rate through the device. In one embodiment, the valve body 128 may include a central cylinder 132 that includes or forms the cavity 130. A pair of closures 134 having through holes 136 may be secured to either side of the central cylinder 132. Fasteners F may be used for this purpose. The closures 134 may have ends 138 flanged for connection to a pipe or conduit, thereby allowing material to enter and exit the cavity 130. Other configurations of end 138 may employ different connection features, such as welded ends, pipe fittings, plug-in flanges, or ring fittings. Valve 126 may also include an actuator shaft 140 that passes through the central cylinder 132 to engage with the throttle ball 118. An actuator may be connected to the actuator shaft 140 to rotate the throttle ball 118 to different positions.
[0025] Figure 6 Depicting Figure 1 A perspective view of an example of a valve core assembly 100. This example maintains the continuity of the annular ring 104. The process may include steps of turning the outer surface 108 downwards and heating the throttling ball 118 to insert, assemble, and orient the annular ring 104 in the appropriate position within the opening 122. As noted herein, the arcuate surfaces at the cuts C1, C2 may be aligned with the edges of the opening 122. A weld 124 secures the annular ring 104 in the appropriate position within the assembly.
[0026] Figure 7 , Figure 8 and Figure 9 Depicting Figure 1 A perspective view of an example valve core assembly 100. The process may include steps of turning the outer surface 108 downwards and drilling (or including) a threaded hole 144. (As...) Figure 8 As shown in the best example, these steps can also form incisions C1 and C2. Figure 9 A valve spool assembly 100 is shown, which is produced by the step of securing a tooling block 146 to an annular ring 104, preferably using fasteners inserted into threaded holes 144. The tooling block 146 allows for the removal of slots 148 from the annular ring 104. This step also allows the manufacturer to more easily insert the annular ring 104 into a throttle ball 118.
[0027] Figure 10 The appropriate position in the throttling ball 118 is depicted. Figure 7 A perspective view of the valve core assembly 100. In one embodiment, these steps involve heating the throttling ball 118 to insert, assemble, and orient the annular ring 104 (with a slot 148) in the appropriate position within the opening 122. A weld 124 secures the annular ring 104 in the assembly.
[0028] Figure 11 A flowchart depicts an exemplary embodiment of method 200 for manufacturing a valve core and assembling a throttling ball for use in a ball valve. Method 200 reduces delivery time, cost, and assembly problems because it does not heat or preheat the throttling ball. In one specific embodiment, the method may include the steps of: (a) manufacturing an annular ring with a noise-reducing element having an outer diameter (step 202); and (b) reducing the outer diameter from a first size to a second size (step 204). These steps may also include steps for forming a notch. Also as shown, the method may further include the steps of: (c) inserting the annular ring at the second size (at step 206) into an opening in the throttling ball (at step 208); and (d) welding the annular ring to the appropriate position in the opening.
[0029] Figure 12 and Figure 13 Other examples of method 200 are shown. Figure 12 In this method 200, the step of heating the throttling ball (at step 210) may be included. Figure 13 An example of method 200 may include the following steps: (f) drilling and threading holes in the annular ring (at step 212); (g) securing a tooling block to the annular ring (at step 214); and (h) forming a slot in the annular ring between the threaded holes.
[0030] In light of the foregoing, the improvements described herein facilitate the manufacture of noise-suppressing spools and throttling balls for use in ball valves and similar flow control devices. These improvements eliminate any steps of heating or preheating the throttling ball, which can potentially take several hours and require skilled or experienced workers. These implementations also avoid the problem of rapid cooling of the throttling ball, which can hinder efforts to properly position the noise-suppressing spool.
[0031] The examples below may include elements or clauses that can be combined with other elements and clauses to describe embodiments contemplated within the scope and substance of this disclosure. This disclosure may include and contemplate other examples that would occur to those skilled in the art. Such other examples are intended to fall within the scope of the claims if they have structural elements that are indistinguishable from the literal language of the claims, or if they include equivalent structural elements that are indistinguishable from the literal language of the claims.
