Description

Technical Field

[0001] The present disclosure generally relates to fluid valves, and more particularly to a valve plug having distributed vanes. Background Art

[0002] Process control systems often employ fluid valves to regulate process fluids. Conventional fluid valves include devices such as plugs, balls, or other fluid flow control members that move within the fluid flow path of the valve to control the fluid flow capacity and affect the flow characteristics through the valve. Typically, a fluid flow control member, such as a valve plug, moves between a fully open position and a closed position. In the fully open position, the valve plug is spaced apart from the valve seat to allow fluid to flow through the passage of the valve. In the closed position, the valve plug engages the valve seat to prevent fluid from flowing through the passage. The valve seat interacts with the sealing surface of the fluid flow control member to restrict and control fluid flow. Typically, turbulence is generated near the valve seat and the fluid flow control member. Summary of the Utility Model

[0003] In one example, an apparatus includes a valve plug body configured to engage a valve seat. The valve plug body includes a plurality of circumferentially spaced vanes. The plurality of circumferentially spaced vanes includes: a first vane; a second vane oriented at a first angle relative to the first vane, the second vane being circumferentially adjacent to the first vane; and a third vane oriented at a second angle relative to the second vane, the third vane being circumferentially adjacent to the first vane, the second angle being different from the first angle.

[0028] Generally, the same reference numerals are used throughout the drawings and the accompanying written description to denote the same or similar components. The drawings are not drawn to scale. Instead, the thickness of these layers or regions may be enlarged in the drawings. Although the drawings show these layers and regions having clean lines and boundaries, some or all of these lines and / or boundaries may be idealized. In reality, the boundaries and / or lines may be unobservable, merged, and / or irregular. Detailed Description

[0029] As used herein, unless otherwise specified, the term "above" describes the relationship of two parts relative to the earth. If a second part has at least one part between the earth and a first part, the first part is above the second part. Similarly, as used herein, when a first part is closer to the earth than a second part, the first part is "below" the second part. As described above, the first part may be above or below the second part, having one or more of the following: having other parts therebetween, having no other parts therebetween, the first part and the second part being in contact, or the first part and the second part not being in direct contact with each other.

[0030] As used in this patent, stating that any part (e.g., a layer, film, region, zone, or plate) is on another part in any way (e.g., being positioned on another part, located on another part, arranged on another part, or formed on another part, etc.) means that the part mentioned is in contact with the other part, or the part mentioned is above the other part, with one or more intermediate parts therebetween.

[0031] As used herein, unless otherwise specified, connecting referents (e.g., attaching, coupling, connecting, and joining) can include intermediate members between the elements involved by the connecting referent and / or relative movement between those elements. Thus, a connecting referent does not necessarily mean that the two elements are directly connected and / or in a fixed relationship to each other. As used herein, the statement that any part "contacts" another part is defined to mean that there is no intermediate part between the two parts.

[0032] Unless otherwise explicitly stated, descriptors such as "first", "second", "third", etc. are used herein without implying or otherwise indicating any meaning of priority, physical order, arrangement in a list, and / or sequencing, but are only used as labels and / or arbitrary names to distinguish elements for ease of understanding the disclosed examples. In some examples, the descriptor "first" can be used to refer to an element in a particular embodiment, while the same element can be referred to by a different descriptor such as "second" or "third" in the claims. In such cases, it should be understood that such descriptors are only used to clearly identify those elements in the context of the discussion (e.g., in the claims), where the elements may, for example, otherwise share the same name.

[0033] As used herein, "about" and "approximately" modify their object / value to identify potential variations that occur in real-world applications. For example, as would be understood by one of ordinary skill in the art, "about" and "approximately" can modify dimensions that may be inaccurate due to manufacturing tolerances and / or other real-world imperfections. For example, "about" and "approximately" can indicate that such dimensions can be within a tolerance range of + / - 10%, unless otherwise specified in the following description.

[0034] A fluid valve is used to control and manage fluid flow between an inlet and an outlet. More specifically, a fluid flow control member (e.g., a valve plug) is typically used to regulate the process fluid flow through the fluid flow passage of the valve. Within the fluid flow passage of the valve, fluid turbulence (e.g., irregular flow, fluid vortices, eddies, etc.) is typically generated under most flow conditions within the fluid flow passage of the fluid valve.

[0035] For example, regions of lower flow resistance (e.g., regions near the valve seat, cavities created by a withdrawn valve plug) can create irregular flow where the pressure and / or velocity of the fluid flow changes. Turbulent fluid flow can cause adverse effects on the desired operation of the fluid valve, such as local flow energy loss, vibration, noise, and reduced flow capacity. In some examples, the vibration caused by fluid vortices can lead to premature wear on valve components. Reduced flow capacity can limit the peak performance of the valve. Thus, minimizing turbulence in the valve flow path can improve the performance and lifespan of valve components.

[0036] The fluid valve plug operates between a closed position and a fully open position. In the closed position, the plug contacts the valve seat to seal the fluid flow passage of the valve. In the fully open position, the plug is withdrawn from the valve seat to allow fluid to flow through the fluid flow passage. In some examples, positioning the plug in an intermediate position (e.g., a position between closed and fully open, etc.) can reduce turbulence and vortex generation within the valve.

[0037] The examples disclosed herein eliminate the above - mentioned deficiencies and include flow - disturbance - reducing members (e.g., valve plugs, valve seat rings, etc.), which include circumferentially non - uniform and / or uniform - distributed vanes to divert and direct the fluid flow. The examples disclosed herein reduce flow turbulence during fluid valve operation. Additional examples disclosed herein include flow - disturbance - reducing members having circumferentially distributed vanes and balance holes, both uniformly and non - uniformly, to equalize fluid pressure across all parts of the valve plug body. In some examples disclosed herein, the flow - disturbance - reducing member is deployed with a valve cage, where the grooves between the vanes are aligned with the cage windows. In some examples disclosed herein, the vanes of the flow - disturbance - reducing member are aligned with the cage windows. Additionally, example flow - disturbance - reducing members are disclosed herein, where the valve seat or seat ring includes a valve having non - uniformly distributed vanes.

[0038] Figure 1 A cross - section of a known fluid valve 100 with an upward - flow configuration is shown, which includes a fluid vortex 102 near the valve seat or seat ring 104. In Figure 1 this case, the fluid valve 100 includes a valve plug 106 withdrawn from sealing contact with the valve seat 104. The fluid valve 100 includes a valve body 108 that defines a fluid flow passage 110 between an inlet 112 and an outlet 114 of the valve 100. In Figure 1 this case, the fluid valve includes a valve cap 116 coupled to the valve body 108 via bolts 118. The fluid valve 100 includes a valve stem 120 to move the valve plug 106 within the valve body 108 between a closed position and a fully open position. In the closed position, the valve plug 106 contacts the valve seat 104 to seal the fluid flow passage 110 between the inlet 112 and the outlet 114. In the fully open position, the valve plug 106 is withdrawn from the valve seat 104 to allow fluid to flow through the fluid flow passage 110 between the inlet 112 and the outlet 114. In some examples, an actuator (e.g., a pneumatic actuator, an electric actuator, a hydraulic actuator, etc.) is used to move the valve stem 120 to move the valve plug 106 within the valve body 108. The valve stem 120 is coupled to the valve plug 106 via a stem orifice 122. In other examples, in addition to sealing and opening the fluid flow passage 110, the valve plug 106 can direct and regulate (e.g., modulate) the fluid flow between the inlet 112 and the outlet 114.

[0039] InFigure 1 In, a fluid vortex 102 is within a cavity 124 of a valve body 108. In Figure 1 In, when fluid flows upward into a lower resistance region of the cavity 124 after passing through a throttling region 126, a fluid vortex 102 is generated. For example, the fluid vortex 102 may be formed in a portion of the cavity 124 that is distal to an outlet 114. The presence of the fluid vortex 102 can have an adverse effect on valve performance, such as local flow energy loss, vibration, and noise. The vibration caused by the fluid vortex 102 can cause wear on a valve plug 106, an interface between the valve plug 106 and a valve stem 120 at a stem orifice 122, the valve stem 120, and / or other valve components.

[0040] Figure 2 FIG. illustrates a cross-section of another known fluid valve 200 having a downward flow configuration, which includes a fluid vortex 202 near a seat ring 204 (such as a valve seat, etc.). In Figure 2 In, the fluid valve 200 includes a valve body 206 and a valve plug 208. In Figure 2 In, the valve plug 208 is in sealing contact with a valve seat 204. The valve body 206 defines a fluid flow passage 210 between an inlet 212 and an outlet 214. Similar to Figure 1 the fluid valve 100, the fluid valve 200 includes a valve stem 216 to move the valve plug 208 within the valve body 206 between a closed position and a fully open position, in the closed position, the valve plug 208 contacts the valve seat 204 to seal the fluid flow passage 210 between the inlet 212 and the outlet 214, and in the fully open position, the valve plug 208 is withdrawn from the valve seat 204 to allow fluid to flow through the fluid flow passage 210 between the inlet 212 and the outlet 214. The valve plug 208 includes a stem orifice 218 to receive the valve stem 216. The valve body 206 includes a cage 220 to direct flow through a cavity 222.

[0041] In Figure 2 In, a fluid vortex 202 is formed in a region 224 of the fluid flow passage 210. In Figure 2 In, a portion of the flow moving through the region 224 is slower than the flow in other portions of the fluid flow passage 210. Thus, the flow through the region 224 will have a relatively slow velocity and relatively high turbulence, and will cause the formation of the fluid vortex 202. The presence of the fluid vortex 202 can have an adverse effect on valve performance, including local flow energy loss, vibration, and noise. The vibration caused by the fluid vortex 202 can cause wear on the valve plug 208, an interface between the valve plug 208 and the valve stem 216 at the stem orifice 218, the valve stem 216, and / or other flow components.

[0042] Figure 3A is a perspective view of an exemplary unbalanced valve plug 300 implemented in accordance with the teachings of the present disclosure. Figure 3B isFigure 3A An elevation view of an exemplary unbalanced valve plug. In Figure 3A and Figure 3B the illustrated example, the valve plug 300 includes an exemplary first vane 302, an exemplary second vane 304, an exemplary third vane 306, an exemplary fourth vane 308, and an exemplary fifth vane 310. The valve plug 300 has an exemplary first end 312 and an exemplary second end 314. In Figure 3A and Figure 3B the illustrated example, the vanes 302, 304, 306, 308, 310 are circumferentially distributed unevenly around and adjacent to the second end 314. In Figure 3A the illustrated example, the outer diameter dimension of the exemplary plug body 316 of the valve plug 300 is designed to be adapted for use in combination with a fluid valve (e.g., Figure 1 the fluid valve 100 of

[0043] In Figure 3A and Figure 3B the illustrated example, the vanes 302, 304, 306, 308, 310 are part of a single body of the valve plug 300 (e.g., the vanes 302, 304, 306, 308, 310 and the plug body 316 are integral components, etc.). In some such examples, the valve plug 300 can be manufactured via machining (e.g., subtractive manufacturing), casting, additive manufacturing, and / or any other suitable method. In other examples, some or all of the vanes 302, 304, 306, 308, 310 can be manufactured separately and joined (e.g., via one or more welds, one or more fasteners, chemical adhesives, press fits, shrink fits, etc.) to the plug body 316 of the valve plug 300.

[0044] In Figure 3A and Figure 3B the illustrated example, the valve plug 300 includes an exemplary first groove 317, an exemplary second groove 318, an exemplary third groove 320, an exemplary fourth groove 322, and an exemplary fifth groove 324. The first groove 317 is formed by a slot defined by the first vane 302 and the second vane 304. The second groove 318 is formed by a slot defined by the second vane 304 and the third vane 306. The third groove 320 is formed by a slot defined by the third vane 306 and the fourth vane 308. The fourth groove 322 is formed by a slot defined by the fourth vane 308 and the fifth vane 310. The fifth groove 324 is formed by a slot defined by the fifth vane 310 and the first vane 302. The first groove 317 and the fifth groove 324 have a first curved profile, while the second groove 318, the third groove 320, and the fourth groove 322 have a second curved profile. In Figure 3A and Figure 3BIn the example shown, the first bending profile and the second bending profile are different. In other examples, the first bending profile and the second bending profile may have the same bending profile. In Figure 3A and Figure 3B the example shown, each of the first groove 317 and the fifth groove 324 spans a greater angular displacement (e.g., defines a greater arc, etc.) than each of the second groove 318, the third groove 320, and the fourth groove 322.

[0045] In Figure 3A and Figure 3B the example shown, the valve plug 300 includes an exemplary valve seat interface portion 326 near the second end 314 of the valve plug 300. To seal the fluid flow passage of the valve (e.g., Figure 1 the fluid flow passage 110), the valve plug 300 can be moved such that the valve seat portion 326 contacts the corresponding surface of the valve seat or seat ring. The valve plug 300 can be coupled to the rod (not shown) of the valve via the first end 312.

[0046] The vanes 302, 304, 306, 308, 310 are circumferentially distributed around the second end 314. In Figure 3B the example shown, the first vane 302 and the second vane 304 define an exemplary first angle 328 therebetween. In Figure 3B the example shown, the second vane 304 and the third vane 306 define an exemplary second angle 330 therebetween. In Figure 3B the example shown, the third vane 306 and the fourth vane 308 define an exemplary third angle 332 therebetween. In Figure 3B the example shown, the fourth vane 308 and the fifth vane 310 define an exemplary fourth angle 334 therebetween. In Figure 3B the example shown, the fifth vane 310 and the first vane 302 define an exemplary fifth angle 336 therebetween. In Figure 3B the example shown, the magnitudes of the first angle 328 and the fifth angle 336 are equal, and the magnitudes of the second angle 330, the third angle 332, and the fourth angle 334 are equal. In other examples, each of the first angle 328, the second angle 330, the third angle 332, the fourth angle 334, and the fifth angle 336 has a different magnitude. In other examples, some or all of the first angle 328, the second angle 330, the third angle 332, the fourth angle 334, and the fifth angle 336 may have equal magnitudes. Additionally or alternatively, the valve plug 300 may include any suitable number of vanes (e.g., 4 vanes, 5 vanes, 6 vanes, etc.).

[0047] In Figure 3B the example shown, the second end 314 of the valve plug 300 defines an exemplary first portion 338 and an exemplary second portion 340. InFigure 3B In the example of, the first portion 338 includes a first number of circumferentially spaced blades, and the second portion 340 includes a second number of circumferentially spaced blades. In this example, the first portion 338 extends clockwise across between the second blade 304 and the fifth blade 310, and includes the first blade 302. The second portion 340 extends clockwise across between the fifth blade 310 and the second blade 304, and includes the third blade 306 and the fourth blade 308. In some examples, the first number of blades of the first portion 338 may be greater than, less than, or equal to the second number of blades of the second portion 340. In other examples, the dimensions of the first portion 338 and the second portion 340 are substantially equal.

[0048] The valve plug 300 can be deployed with any type of slide valve (e.g., ball valve, angle valve, etc.). The valve plug 300 can be deployed in various orientations relative to the flow through the fluid flow channel to have a desired effect on the generation of turbulence. For example, the valve plug 300 can be oriented such that the portion with the largest number of blades is oriented close to the vortex region (e.g., the second portion 340 is aligned with Figure 1 the fluid vortex 102). In some examples, the orientation of the valve plug 300 relative to the flow through the fluid flow channel can be determined by the orientation of the valve plug 300 coupled to the valve stem.

[0049] During operation, the valve including the valve plug 300 can move the valve plug 300 between a fully open position (e.g., the plug is fully withdrawn from the sealing surface of the valve seat), a fully closed position (e.g., the plug is in sealing contact with the valve seat), and other positions therebetween. In some examples, when the valve plug 300 is withdrawn from the sealing contact with the valve seat (e.g., Figure 1 the valve seat 104), fluid flows through the second end 314 of the valve plug 300. In some such examples, the fluid flowing through the valve seat is diverted by the blades 302, 304, 306, 308, 310 and is guided through the valve seat by the grooves 317, 318, 320, 322, 324. The guiding of the fluid flow by the valve plug 300 reduces the generation of turbulence because the fluid flow is guided through the fluid flow channel and away from the regions that cause low flow resistance regions (e.g., Figure 1 the cavity 124, Figure 2 the region 224, etc.). In some examples, compared with an existing valve plug (e.g., Figure 1 the valve plug 106), the valve plug 300 reduces the adverse effects associated with vortices (e.g., vibration, reduced flow capacity, etc.).

[0050] Figure 4A is a perspective view of an exemplary balance valve plug 400 implemented in accordance with the teachings of the present disclosure. Figure 4B is Figure 4ABottom view of an exemplary valve plug 400. In Figure 4A and Figure 4B the illustrated example, the valve plug 400 includes an exemplary first vane 402, an exemplary second vane 404, an exemplary third vane 406, an exemplary fourth vane 408, and an exemplary fifth vane 410. The valve plug 400 has an exemplary first end 412 and an exemplary second end 414. In Figure 4A and Figure 4B the illustrated example, the vanes 402, 404, 406, 408, 410 are unevenly circumferentially distributed around the second end 414. In Figure 4A the illustrated example, the outer diameter dimension of the exemplary plug body 416 of the valve plug 400 is designed to be suitable for use in combination with a fluid valve (e.g., Figure 1 the fluid valve 100, etc.) of

[0051] In Figure 4A and Figure 4B the illustrated example, the vanes 402, 404, 406, 408, 410 are part of a single body of the valve plug 400 (e.g., the vanes 402, 404, 406, 408, 410 and the plug body are integral components, etc.). In some such examples, the valve plug 400 can be manufactured via machining (e.g., negative manufacturing), casting, additive manufacturing, and / or any other suitable method. In other examples, some or all of the vanes 402, 404, 406, 408, 410 can be coupled (e.g., via one or more welds, one or more fasteners, chemical adhesives, press fits, shrink fits, etc.) to the plug body 416 of the valve plug 400.

[0052] In Figure 4A and Figure 4B the illustrated example, the valve plug 400 includes an exemplary first groove 418, an exemplary second groove 420, an exemplary third groove 422, an exemplary fourth groove 424, and an exemplary fifth groove 426. The first groove 418 is formed by a groove defined by the first vane 402 and the second vane 404. The second groove 418 is formed by a groove defined by the second vane 404 and the third vane 406. The third groove 422 is formed by a groove defined by the third vane 406 and the fourth vane 408. The fourth groove 424 is formed by a groove defined by the fourth vane 408 and the fifth vane 410. The fifth groove 426 is formed by a groove defined by the fifth vane 410 and the first vane 402. The first groove 418 and the fifth groove 426 have a first curved profile, and the second groove 420, the third groove 422, and the fourth groove 424 have a second curved profile. In Figure 4A and Figure 4B the illustrated example, the first curved profile and the second curved profile are different. In other examples, the first curved profile and the second curved profile can be the same curved profile. In Figure 4A and Figure 4BIn the example shown, the first groove 418 and the fifth groove 426 span a greater angular displacement (e.g., define a greater arc, etc.) than the second groove 420, the third groove 422, and the fourth groove 424.

[0053] In Figure 4A and Figure 4B the example shown, the valve plug 400 includes an exemplary first balance hole 428, an exemplary second balance hole 430, an exemplary third balance hole 432, an exemplary fourth balance hole 434, and an exemplary fifth balance hole 436. The first balance hole 428 is disposed within the first groove 418, the second balance hole 430 is disposed within the second groove 420, the third balance hole 432 is disposed within the third groove 422, the fourth balance hole 434 is disposed within the fourth groove 424, and the fifth balance hole 436 is disposed within the fifth groove 426. In some examples, the balance holes 428, 430, 432, 434, 436 enable fluid to travel to the chamber above the valve plug 400 to equalize the fluid pressure on all sides of the valve plug 400 to facilitate movement of the valve plug 400 without an additional force to compensate for the pressure differential across the valve plug 400.

[0054] In Figure 4A and Figure 4B the example shown, the valve plug 400 includes an exemplary valve seat interface portion 438 proximate the second end 414 of the valve plug 400. To seal the fluid flow passage of the valve (e.g., Figure 1 the fluid flow passage 110 of

[0055] etc.), the valve plug 400 can be moved such that the valve seat portion 438 mates with the surface of a valve seat and / or seat ring. The valve plug 400 can be coupled to a rod (not shown) of the valve via the first end 412. Figure 4A and Figure 4B the example shown, the vanes 402, 404, 406, 408, 410 are circumferentially distributed about the second end 414. In Figure 4B the example shown, the first vane 402 and the second vane 404 define an exemplary first angle 440 therebetween. In Figure 4B the example shown, the second vane 404 and the third vane 406 define an exemplary second angle 442 therebetween. In Figure 4B the example shown, the third vane 406 and the fourth vane 408 define an exemplary third angle 444 therebetween. In Figure 4B the example shown, the fourth vane 408 and the fifth vane 410 define an exemplary fourth angle 446 therebetween. In Figure 4B the example shown, the fifth vane 410 and the first vane 402 define an exemplary fifth angle 448 therebetween. In Figure 4BIn the example shown, the first angle 440 and the fifth angle 448 are equal in size, and the second angle 442, the third angle 444, and the fourth angle 446 are equal in size. In other examples, each of the first angle 440, the second angle 442, the third angle 444, the fourth angle 446, and the fifth angle 448 has a different size. In other examples, some or all of the first angle 440, the second angle 442, the third angle 444, the fourth angle 446, and the fifth angle 448 may have equal sizes. Additionally or alternatively, the valve plug 400 may include any suitable number of vanes (e.g., 4 vanes, 5 vanes, 6 vanes, etc.).

[0056] In Figure 4B the example shown, the second end 414 of the valve plug 400 defines an example first portion 450 and an example second portion 452. In Figure 4B the example, the first portion 450 includes a first number of circumferentially spaced vanes, and the second portion 452 includes a second number of circumferentially spaced vanes. In this example, the first portion 450 extends clockwise across between the second vane 404 and the fifth vane 410 and includes the first vane 402. The second portion 452 extends clockwise across between the fifth vane 410 and the second vane 404 and includes the third vane 406 and the fourth vane 408. In some examples, the first number of vanes of the first portion 450 is greater than, less than, or equal to the second number of vanes of the second portion 452. In other examples, the dimensions of the first portion 450 and the second portion 452 are substantially equal.

[0057] Similar to Figure 3A and Figure 3B the valve plug 300, the valve plug 400 can be deployed with any type of slide valve (e.g., ball valve, angle valve, etc.) and can be in various orientations relative to the fluid flow through the fluid flow channel. For example, the valve plug 400 can be oriented such that the portion with the largest number of vanes is oriented near the vortex region (e.g., the second portion 452 is aligned with Figure 1 the fluid vortex 102). The vanes 402, 404, 406, 408, 410 and the grooves 418, 420, 422, 424, 426 guide the fluid flow through the valve seat. The guiding of the fluid flow by the valve plug 400 reduces the generation of turbulence because the flow is guided through the fluid flow channel and away from regions that cause low flow resistance regions (e.g., Figure 1 the cavity 124, Figure 2 the region 224, etc.) that cause turbulence. Similar to the valve plug 300 of FIG. 3, when compared with an existing valve plug (e.g., Figure 1 the valve plug 106, etc.), the use of the valve plug 400 can reduce the adverse effects associated with vortices (e.g., vibration, reduced flow capacity, etc.).

[0058] Figure 5A is a perspective view of an exemplary valve plug 500 implemented in accordance with the teachings of the present disclosure. Figure 5B is Figure 5A a bottom view of an exemplary balanced and simplified valve plug 500. In the Figure 5A and Figure 5B illustrated example, the valve plug 500 includes an exemplary first vane 502, an exemplary second vane 504, an exemplary third vane 506, and an exemplary fourth vane 508. The valve plug 500 has an exemplary first end 510 and an exemplary second end 512. In the Figure 5A and Figure 5B illustrated example, the vanes 502, 504, 506, 508 are distributed around and near the second end 512. In the Figure 5A illustrated example, the outer diameter dimension of the exemplary plug body 514 of the valve plug 500 is designed to be adapted for use in combination with a fluid valve (e.g., Figure 1 the fluid valve 100 of

[0059] In the Figure 5A and Figure 5B illustrated examples, the vanes 502, 504, 506, 508 are part of a single body of the valve plug 500 (e.g., the vanes 502, 504, 506, 508 and the plug body are integral components, etc.). In some such examples, the valve plug 500 can be manufactured by machining (e.g., negative manufacturing), casting, additive manufacturing, and / or any other suitable method. In other examples, some or all of the vanes 502, 504, 506, 508 can be coupled (e.g., via one or more welds, one or more fasteners, chemical adhesives, press fits, shrink fits, etc.) to the plug body 514 of the valve plug 500.

[0060] In the Figure 5A and Figure 5B illustrated example, the valve plug 500 includes an exemplary first groove 516, an exemplary second groove 518, an exemplary third groove 520, and an exemplary fourth groove 522. The first groove 516 is formed by a groove defined by the first vane 502 and the second vane 504. The second groove 518 is formed by a groove defined by the second vane 504 and the third vane 506. The third groove 520 is formed by a groove defined by the third vane 506 and the fourth vane 508. The fourth groove 522 is formed by a groove defined by the fourth vane 508 and the first vane 502. In the Figure 5A and Figure 5BIn the example shown, the second groove 518, the third groove 520, and the fourth groove 522 have concave bends, while the first groove 516 has: a first bent portion 524 with a concave bend, a second bent portion 526 with a convex bend, and a third bent portion 528 with a concave bend. The exemplary first groove 516 has a greater angular displacement (e.g., defining a greater arc, etc.) than each of the second groove 518, the third groove 520, and the fourth groove 522.

[0061] In Figure 5A and Figure 5B the example shown, the valve plug 500 includes an exemplary first balance hole 530, an exemplary second balance hole 532, an exemplary third balance hole 534, an exemplary fourth balance hole 536, and an exemplary fifth balance hole 538. The first balance hole 530 is disposed within the second groove 518. The second balance hole 532 and the third balance hole 534 are disposed within the first groove 516. The fourth balance hole 536 is disposed within the fourth groove 522. The fifth balance hole 538 is disposed within the third groove 520. In some examples, the balance holes 530, 532, 534, 536, 538 enable fluid to travel to the chamber above the valve plug 500 to equalize the fluid pressure on all sides of the valve plug 500 to facilitate the desired movement of the valve plug 500 without the need for additional force to compensate for the pressure difference on the sides of the valve plug. In Figure 5A and Figure 5B the example shown, the valve plug 500 includes an exemplary valve seat interface portion 540 near the second end 512 of the valve plug 500. To seal the fluid flow passage of the valve (e.g., Figure 1 the fluid flow passage 110, etc.), the valve plug 500 can be moved such that the valve seat interface portion 540 meets the surface of the valve seat or seat ring. The valve plug 500 can be coupled to the rod (not shown) of the valve via the first end 510.

[0062] The vanes 502, 504, 506, 508 are circumferentially distributed around the second end 512. In Figure 5B the example shown, the first vane 502 and the second vane 504 define an exemplary first angle 542 therebetween. In Figure 5B the example shown, the second vane 504 and the third vane 506 define an exemplary second angle 544 therebetween. In Figure 5B the example shown, the third vane 506 and the fourth vane 508 define an exemplary third angle 546 therebetween. In Figure 5B the example shown, the fourth vane 508 and the first vane 502 define an exemplary fourth angle 548 therebetween. In Figure 5BIn the example shown, the second angle 544, the third angle 546, and the fourth angle 548 are of equal size, and the size of the first angle 542 is different from the sizes of the second angle 544, the third angle 546, and the fourth angle 548. In other examples, each of the first angle 542, the second angle 544, the third angle 546, and the fourth angle 548 has a different size. In other examples, some or all of the first angle 542, the second angle 544, the third angle 546, and the fourth angle 548 may have equal sizes. Additionally or alternatively, the valve plug 500 may include any suitable number of vanes (e.g., 4 vanes, 5 vanes, 6 vanes, etc.).

[0063] In Figure 5B the example shown, the second end 512 of the valve plug 500 defines an example first portion 550 and an example second portion 552. In Figure 5B the example, the first portion 550 includes a first number of circumferentially spaced vanes, and the second portion 552 includes a second number of circumferentially spaced vanes. In this example, the first portion 550 spans clockwise between the second vane 504 and the first vane 502. The second portion 552 spans clockwise between the first vane 502 and the second vane 504, and includes a third vane 506 and a fourth vane 508. In some examples, the first number of vanes of the first portion 550 is greater than, less than, or equal to the second number of vanes of the second portion 552. In other examples, the first portion 550 and the second portion 552 are substantially equal in size.

[0064] Similar to Figure 3A and Figure 3B the valve plug 300 and Figure 4A and Figure 4B the valve plug 400, the valve plug 500 can be deployed with any type of slide valve, and can be deployed in various orientations (e.g., oriented such that the second portion 552 is aligned with Figure 1 the fluid vortex 102). In some examples, when the valve plug 500 is withdrawn from sealing contact with a valve seat (e.g., Figure 1 the valve seat 104), fluid flows through the second end 512, and is split by the vanes 502, 504, 506, 508, and is guided through the valve seat by the grooves 516, 518, 520, 522, thereby reducing the generation of turbulence. When compared to existing valve plugs (e.g., Figure 1 the valve plug 106, etc.), the use of the valve plug 500 reduces the adverse effects associated with the vortex (e.g., vibration, reduced flow capacity, etc.). In some examples, the valve plug 500 can be simplified for different applications by reducing the number of vanes and / or grooves.

[0065] Figure 6APerspective view of another exemplary valve plug 600 implemented in accordance with the teachings of the present disclosure. Figure 6B Is Figure 6A Bottom view of an exemplary unbalanced, straight leg valve plug 600. The valve plug 600 includes exemplary first vane 602, exemplary second vane 604, exemplary third vane 606, exemplary fourth vane 608, exemplary fifth vane 610, and exemplary sixth vane 612. In Figure 6A And Figure 6B In the illustrated example, the valve plug 600 has an exemplary first end 614 and an exemplary second end 616 with vanes 602, 604, 606, 608, 610, 612. The vanes 602, 604, 606, 608, 610, 612 are circumferentially distributed unevenly and close to the second end 616 around the second end 616. In Figure 6A In the illustrated example, the outer diameter dimension of the exemplary plug body 618 of the valve plug 600 is designed to be suitable for use in combination with a fluid valve (e.g., Figure 1 Fluid valve 100).

[0066] In Figure 6A And Figure 6B In the illustrated example, the vanes 602, 604, 606, 608, 610, 612 are part of a single body of the valve plug 600 (e.g., the vanes 602, 604, 606, 608, 610, 612 and the plug body 618 are integral components, etc.). In some such examples, the valve plug 600 can be manufactured by machining (e.g., negative manufacturing), casting, additive manufacturing, and / or any other suitable method. In other examples, some or all of the vanes 602, 604, 606, 608, 610, 612 can be coupled (e.g., via one or more welds, one or more fasteners, chemical adhesives, press fits, shrink fits, etc.) to the plug body 618 of the valve plug 600. In the example shown in FIG. 6, the wall of each vane of the vanes 602, 604, 606, 608, 610, 612 of the valve plug 600 is flat (e.g., planar, etc.). In other examples, some or all of the vanes 602, 604, 606, 608, 610, 612 can include curved walls (e.g., similar to Figure 3A And Figure 3B Valve plug 300, similar to Figure 4A And Figure 4B Valve plug 400, similar to Figure 5A And Figure 5B Valve plug 500, etc.).

[0067] In Figure 6A And Figure 6BIn the example shown, the valve plug 600 includes an example first gap 620, an example second gap 622, an example third gap 624, an example fourth gap 626, an example fifth gap 628, and an example sixth gap 630. The first gap 620 is formed by the space between the first vane 602 and the second vane 604. The second gap 622 is formed by the space between the second vane 604 and the third vane 606. The third gap 624 is formed by the space between the third vane 606 and the fourth vane 608. The fourth gap 626 is formed by the space between the fourth vane 608 and the fifth vane 610. The fifth gap 628 is formed by the space between the fifth vane 610 and the sixth vane 612. The sixth gap 630 is formed by the space between the sixth vane 612 and the first vane 602.

[0068] In Figure 6A and Figure 6B the example shown, the valve plug 600 includes an example valve seat interface portion 632 near the second end 616 of the valve plug 600. To seal the fluid flow passage of the valve (e.g., Figure 1 the fluid flow passage 110), the valve plug 600 can be moved such that the valve seat portion 632 meets the surface of a valve seat or seat ring. The valve plug 600 can be coupled to a rod (not shown) of the valve via the first end 614.

[0069] The vanes 602, 604, 606, 608, 610, 612 are circumferentially distributed around the second end 616. In Figure 6B the example shown, the first vane 602 and the second vane 604 define an example first angle 634 therebetween. In Figure 6B the example shown, the second vane 604 and the third vane 606 define an example second angle 636 therebetween. In Figure 6B the example shown, the third vane 606 and the fourth vane 608 define an example third angle 638 therebetween. In Figure 6B the example shown, the fourth vane 608 and the fifth vane 610 define an example fourth angle 640 therebetween. In Figure 6B the example shown, the fifth vane 610 and the sixth vane 612 define an example fifth angle 642 therebetween. In Figure 6B the example shown, the sixth vane 612 and the first vane 602 define an example sixth angle 644 therebetween. In Figure 6BIn the example shown, the second angle 636, the third angle 638, the fourth angle 640, and the fifth angle 642 are of equal size, and the first angle 634 and the sixth angle 644 are of equal size. In other examples, each of the first angle 634, the second angle 636, the third angle 638, the fourth angle 640, the fifth angle 642, and the sixth angle 644 has a different size. In other examples, some or all of the first angle 634, the second angle 636, the third angle 638, and the fourth angle 640 may have equal sizes. In Figure 6B the example shown, the second angle 636, the third angle 638, the fourth angle 640, and the fifth angle 642 are the same, while the first angle 634 and the sixth angle 644 are different. In some examples, all of the first angle 634, the second angle 636, the third angle 638, the fourth angle 640, the fifth angle 642, and the sixth angle 644 are different, while in other examples, one or more of them are equal. In other examples, if the sizes of the angles 634, 636, 638, 640, 642, 644 are equal, the vanes 602, 604, 606, 608, 610, 612 are circumferentially evenly distributed around the valve plug. Additionally or alternatively, the valve plug 600 may include any suitable number of vanes (e.g., 4 vanes, 5 vanes, 6 vanes, etc.).

[0070] In Figure 6B the example shown, the second end 616 of the valve plug 600 defines an example first portion 646 and an example second portion 648. In Figure 6B the example, the first portion 646 includes a first number of circumferentially spaced vanes, and the second portion 648 includes a second number of circumferentially spaced vanes. In this example, the first portion 646 extends clockwise between the second vane 604 and the sixth vane 612 and includes the first vane 602. The second portion 648 extends clockwise between the sixth vane 612 and the second vane 604 and includes the third vane 606, the fourth vane 608, and the fifth vane 610. In some examples, the first number of vanes in the first portion 646 is greater than, less than, or equal to the second number of vanes in the second portion 648. In other examples, the sizes of the first portion 646 and the second portion 648 are substantially equal.

[0071] Similar to the valve plugs 300, 400, 500, the valve plug 600 can be deployed with any type of slide valve (e.g., ball valve, angle valve, etc.) and in various orientations relative to the flow through the fluid flow channel (e.g., the second portion 648 is aligned with Figure 1 the fluid vortex 102). In some examples, when the valve plug 600 is moved from being in contact with the valve seat (e.g., Figure 1When withdrawn from the sealing contact of the valve seat 104), fluid flows through the valve seat and is split by the vanes 602, 604, 606, 608, 610, 612 and guided away through the gaps 620, 622, 624, 626, 628, 630 to result in a low flow resistance region (e.g., Figure 1 the cavity 124, Figure 2 the region 224, etc.). In some examples, when compared with an existing valve plug (e.g., Figure 1 the valve plug 106, etc.), the valve plug 600 reduces the adverse effects associated with vortices (e.g., vibration, reduced flow capacity, etc.).

[0072] Figure 7A is a front view of an example valve plug 700 disposed within an example valve cage 702 implemented in accordance with the teachings of the present disclosure. Figure 7B is Figure 7A a bottom view of the example valve plug 700. In Figure 7A and Figure 7B the example shown, the valve plug 700 includes an example first vane 704, an example second vane 706, an example third vane 708, an example fourth vane 710, an example fifth vane 712, and an example sixth vane 714. Additionally, in Figure 7A and Figure 7B the example shown, the valve cage 702 includes an example first cage window 716, an example second cage window 718, an example third cage window 720, an example fourth cage window 722, an example fifth cage window 724, and an example sixth cage window 726. The valve plug 700 has an example first end 728 and an example second end 730. In Figure 7A and Figure 7B the example shown, the vanes 704, 706, 708, 710, 712, 714 are distributed around and near the second end 730.

[0073] In Figure 7A and Figure 7B the example, the vanes 704, 706, 708, 710, 712, 714 are part of a single body of the valve plug 700 (e.g., the vanes 704, 706, 708, 710, 712, 714 and the body of the plug 700 are integral components, etc.). In some such examples, the valve plug 700 can be manufactured via machining (e.g., negative manufacturing), casting, additive manufacturing, and / or any other suitable method. In other examples, some or all of the vanes 704, 706, 708, 710, 712, 714 can be coupled (e.g., via one or more welds, one or more fasteners, chemical adhesives, press fits, shrink fits, etc.) to the valve plug 700.

[0074] In Figure 7A and Figure 7BIn the example shown, the valve plug 700 includes an example first groove 732, an example second groove 734, an example third groove 736, an example fourth groove 738, an example fifth groove 740, and an example sixth groove 742. The first groove 732 is formed by a groove defined by a first vane 704 and a second vane 706. The second groove 734 is formed by a groove defined by the second vane 706 and a third vane 708. The third groove 736 is formed by a groove defined by the third vane 708 and a fourth vane 710. The fourth groove 738 is formed by a groove defined by the fourth vane 710 and a fifth vane 712. The fifth groove 740 is formed by a groove defined by the fifth vane 712 and a sixth vane 714. The sixth groove 742 is formed by a groove defined by the sixth vane 714 and the first vane 704.

[0075] The vanes 704, 706, 708, 710, 712, 714 are circumferentially distributed around the second end 730. In Figure 7B the example shown, the first vane 704 and the second vane 706 define an example first angle 744 therebetween. In Figure 7B the example shown, the second vane 706 and the third vane 708 define an example second angle 746 therebetween. In Figure 7B the example shown, the third vane 708 and the fourth vane 710 define an example third angle 748 therebetween. In Figure 7B the example shown, the fourth vane 710 and the fifth vane 712 define an example fourth angle 750 therebetween. In Figure 7B the example shown, the fifth vane 712 and the sixth vane 714 define an example fifth angle 752 therebetween. In Figure 7B the example shown, the sixth vane 714 and the first vane 704 define an example sixth angle 754 therebetween. In Figure 7BIn the example shown, the first angle 744, the second angle 746, the third angle 748, the fourth angle 750, the fifth angle 752, and the sixth angle 754 are of equal size. In other examples, each of the first angle 744, the second angle 746, the third angle 748, the fourth angle 750, the fifth angle 752, and the sixth angle 754 has a different size. Additionally or alternatively, the valve plug 700 can include any suitable number of vanes (e.g., 4 vanes, 6 vanes, 8 vanes, etc.). In some examples, the number of vanes 704, 706, 708, 710, 712, 714 can be equal to the number of cage windows 716, 718, 720, 722, 724, 726 (e.g., 4 vanes and 4 windows, 6 vanes and 3 windows, 8 vanes and 4 windows, etc.), or an integer multiple of the number of cage windows 716, 718, 720, 722, 724, 726. In other examples, the number of vanes 704, 706, 708, 710, 712, 714 can be less than the number of cage windows 716, 718, 720, 722, 724, 726. In Figure 7A and Figure 7B In the example shown, the first groove 732 is circumferentially aligned with the cage window 716, the second groove 734 is circumferentially aligned with the cage window 718, the third groove 736 is circumferentially aligned with the cage window 720, the fourth groove 738 is circumferentially aligned with the cage window 722, the fifth groove 740 is circumferentially aligned with the cage window 724, and the sixth groove 742 is circumferentially aligned with the cage window 726. In other examples, some or all of the vanes 704, 706, 708, 710, 712, 714 are circumferentially aligned with the cage windows 716, 718, 720, 722, 724, 726. Examples of valve plugs and cages including circumferentially aligned cage windows and vanes are described below in conjunction with Figure 8A and Figure 8B

[0076] The valve plug 700 can be deployed with any type of sliding stem valve (e.g., ball valve, angle valve, etc.). During operation, a valve including the valve plug 700 can move the valve plug 700 between a fully open position (e.g., the plug is fully withdrawn from the sealing surface of the valve seat), a fully closed position (e.g., the plug is in sealing contact with the valve seat), and other positions therebetween. In some examples, when the valve plug 700 moves from being in contact with the valve seat (e.g., Figure 1 ​When the sealing contact of the valve seat 104) is withdrawn, fluid flows through the second end 730 of the valve plug 700. In some such examples, the fluid flowing through the valve seat is split by the cage windows 716, 718, 720, 722, 724, 726 and the vanes 704, 706, 708, 710, 712, 714, and is guided through the valve seat by the grooves 732, 734, 736, 738, 740, 742. The guiding of the fluid flow by the valve plug 700 reduces the generation of turbulence because the flow is guided through the fluid flow channels and away from areas that cause low flow resistance regions (e.g., Figure 1 the cavity 124, Figure 2 the region 224, etc.). When compared with existing valve plugs (e.g., Figure 1 the valve plug 106, etc.), the use of the valve plug 700 reduces the adverse effects associated with vortices (e.g., vibration, reduced flow capacity, etc.).

[0077] Figure 8A is a front view of an example valve plug 800 disposed within an example valve cage 802 implemented in accordance with the teachings of the present disclosure. Figure 8B is Figure 8A a bottom view of the example valve plug 800. In Figure 8A and Figure 8B the example shown, the valve plug 800 includes an example first vane 804, an example second vane 806, an example third vane 808, an example fourth vane 810, an example fifth vane 812, and an example sixth vane 814. Additionally, in Figure 8A and Figure 8B the example shown, the valve cage 802 includes an example first cage window 816, an example second cage window 818, an example third cage window 820, an example fourth cage window 822, an example fifth cage window 824, and an example sixth cage window 826. The valve plug 800 has an example first end 828 and an example second end 830, where the vanes 804, 806, 808, 810, 812, 814 are distributed around and near the second end 830.

[0078] In Figure 8A and Figure 8B the example, the vanes 804, 806, 808, 810, 812, 814 are part of a single body of the valve plug 800 (e.g., the vanes 804, 806, 808, 810, 812, 814 and the plug body are integral components, etc.). In some such examples, the valve plug 800 can be manufactured via machining (e.g., negative manufacturing), casting, additive manufacturing, and / or any other suitable method. In other examples, some or all of the vanes 804, 806, 808, 810, 812, 814 can be coupled (e.g., via one or more welds, one or more fasteners, chemical adhesives, press fits, shrink fits, etc.) to the valve plug 800.

[0079] In Figure 8A and Figure 8B In the example shown, the valve plug 800 includes an exemplary first groove 832, an exemplary second groove 834, an exemplary third groove 836, an exemplary fourth groove 838, an exemplary fifth groove 840, and an exemplary sixth groove 842. The first groove 832 is formed by a groove defined by a first vane 804 and a second vane 806. The second groove 834 is formed by a groove defined by the second vane 806 and a third vane 808. The third groove 836 is formed by a groove defined by the third vane 808 and a fourth vane 810. The fourth groove 838 is formed by a groove defined by the fourth vane 810 and a fifth vane 812. The fifth groove 840 is formed by a groove defined by the fifth vane 812 and a sixth vane 814. The sixth groove 842 is formed by a groove defined by the sixth vane 814 and the first vane 804.

[0080] The vanes 804, 806, 808, 810, 812, 814 are circumferentially distributed around the second end 830. In Figure 8B In the example shown, the first vane 804 and the second vane 806 define an exemplary first angle 844 therebetween. In Figure 8B In the example shown, the second vane 806 and the third vane 808 define an exemplary second angle 846 therebetween. In Figure 8B In the example shown, the third vane 808 and the fourth vane 810 define an exemplary third angle 848 therebetween. In Figure 8B In the example shown, the fourth vane 810 and the fifth vane 812 define an exemplary fourth angle 850 therebetween. In Figure 8B In the example shown, the fifth vane 812 and the sixth vane 814 define an exemplary fifth angle 852 therebetween. In Figure 8B In the example shown, the sixth vane 814 and the first vane 804 define an exemplary sixth angle 854 therebetween. In Figure 8BIn the example shown, the first angle 844, the second angle 846, the third angle 848, the fourth angle 850, the fifth angle 852, and the sixth angle 854 are of equal size. In other examples, each of the first angle 844, the second angle 846, the third angle 848, the fourth angle 850, the fifth angle 852, and the sixth angle 854 has a different size. Additionally or alternatively, the valve plug 800 can include any suitable number of vanes (e.g., 4 vanes, 5 vanes, 6 vanes, etc.). In some examples, if the vanes 804, 806, 808, 810, 812, 814 are circumferentially and evenly spaced around the valve plug 800, the number of vanes 804, 806, 808, 810, 812, 814 can be equal to the number of cage windows 816, 818, 820, 822, 824, 826 or an integer multiple of the number of cage windows 816, 818, 820, 822, 824, 826 (e.g., 4 vanes and 4 windows, 6 vanes and 3 windows, 8 vanes and 4 windows, etc.). In other examples, the number of vanes 804, 806, 808, 810, 812, 814 can be less than the number of cage windows 816, 818, 820, 822, 824, 826. In Figure 8A and Figure 8B the example shown, the first vane 804 is aligned with the cage window 816, the second vane 806 is aligned with the cage window 818, the third vane 808 is aligned with the cage window 820, the fourth vane 810 is aligned with the cage window 822, the fifth vane 812 is aligned with the cage window 824, and the sixth vane 814 is aligned with the cage window 826.

[0081] Similar to Figure 7A and Figure 7B the valve plug 700, the valve plug 800 can be deployed with any type of slide valve (e.g., ball valve, angle valve, etc.). In some examples, when the valve plug 800 is withdrawn from sealing contact with a valve seat (e.g., Figure 1 the valve seat 104), the fluid flowing through the valve seat is diverted by the cage windows 816, 818, 820, 822, 824, 826 and the vanes 804, 806, 808, 810, 812, 814 and is directed away from turbulence that causes low flow resistance regions through the grooves 832, 834, 836, 838, 840, 842. When compared to an existing valve plug (e.g., Figure 1 the valve plug 106, etc.), the use of the valve plug 800 reduces the adverse effects associated with vortices (e.g., vibration, reduced flow capacity, etc.).

[0082] Figure 9A is a front view 900 of an example valve seat ring 906 implemented in accordance with the teachings of the present disclosure, Figure 9B is an example top view 902, Figure 9CThis is an example bottom view 904. The valve seat ring 906 includes example first vane 908, example second vane 910, example third vane 912, example fourth vane 914, example fifth vane 916, and example sixth vane 918 that are unevenly distributed around the valve seat ring 906. In Figure 9A - Figure 9C the example, the unevenly distributed vanes 908, 910, 912, 914, 916, 918 are part of a single body of the valve seat ring 906 (e.g., the vanes 908, 910, 912, 914, 916, 918 and the valve seat ring body are integral components, etc.). In some such examples, the valve seat ring 906 can be manufactured via machining (e.g., negative manufacturing), casting, additive manufacturing, and / or any other suitable method. In other examples, some or all of the vanes 908, 910, 912, 914, 916, 918 can be coupled (e.g., via one or more welds, one or more fasteners, chemical adhesives, press fits, shrink fits, etc.) to the valve seat ring 906. In Figure 9A - Figure 9C the example shown, the vanes 908, 910, 912, 914, 916, 918 of the valve seat ring 906 have flat walls (e.g., planar walls, etc.).

[0083] The dimensions of an example outer surface 920 of the valve seat ring 906 are designed to function within the body of the valve (e.g., Figure 1 the valve body 108 of valve 100, etc.). The valve seat ring 906 is disposed within the fluid flow passage of the valve body such that the path of movement of the valve seat ring 906 between a sealing position (i.e., the valve plug meets the valve seat ring 906) and an open position (i.e., the valve plug is withdrawn from the surface of the valve seat ring 906) is aligned with the valve plug. A portion of the valve body is sized to receive the valve seat ring. In some examples, the valve seat ring 906 can include threads to fasten the valve seat ring 906 to the valve body. The valve seat ring 906 has an example first end 922 and an example second end 924 where the vanes 908, 910, 912, 914, 916, 918 begin near the second end 924 and extend along the stem below the valve seat ring 906. Different from Figure 10A - Figure 10C the example of the valve seat ring 1006 shown, the vanes 908, 910, 912, 914, 916, 918 do not extend through the valve seat ring 906 to the first end 922. The valve seat ring 906 can be deployed with any type of slide stem valve (e.g., ball valve, angle valve, etc.). In some examples, the valve seat ring 906 can be deployed with additional flow disturbance reducing members (e.g., valve plugs 300, 400, 500, 600, etc.).

[0084] In Figure 9A - Figure 9CIn the example shown, the valve seat ring 906 includes an example first angle 926, an example second angle 928, an example third angle 930, an example fourth angle 932, an example fifth angle 934, and an example sixth angle 936. The first angle 926 is defined by the angular displacement between the first vane 908 and the second vane 910. The second angle 928 is defined by the angular displacement between the second vane 910 and the third vane 912. The third angle 930 is defined by the angular displacement between the third vane 912 and the fourth vane 914. The fourth angle 932 is defined by the angular displacement between the fourth vane 914 and the fifth vane 916. The fifth angle 934 is defined by the angular displacement between the fifth vane 916 and the sixth vane 918. The sixth angle 936 is defined by the angular displacement between the sixth vane 918 and the first vane 908.

[0085] In Figure 9A - Figure 9C the example shown, the first angle 926, the second angle 928, the third angle 930, and the fourth angle 932 have the same magnitude, while the fifth angle 934 and the sixth angle 936 have different magnitudes. In some examples, the first angle 926, the second angle 928, the third angle 930, the fourth angle 932, the fifth angle 934, and the sixth angle 936 all have the same magnitude, while in other examples, one or more have the same magnitude. In other examples, if the angles 926, 928, 930, 932, 934, 936 are of equal magnitude, then the vanes 908, 910, 912, 914, 916, 918 are circumferentially uniformly distributed around the valve plug.

[0086] In Figure 9A - Figure 9C the example shown, the second end 924 of the valve seat ring 906 defines an example first portion 938 and an example second portion 940. In Figure 9A - Figure 9C the example, the first portion 938 includes a first number of circumferentially spaced vanes, and the second portion 940 includes a second number of circumferentially spaced vanes. In this example, the first portion 938 extends clockwise across between the first vane 908 and the fifth vane 916 and includes the sixth vane 918. The second portion 940 extends clockwise across between the fifth vane 916 and the first vane 908 and includes the second vane 910, the third vane 912, and the fourth vane 914. In some examples, the first number of vanes in the first portion 938 is greater than, less than, or equal to the second number of vanes in the second portion 940. In other examples, the first portion 938 and the second portion 940 are substantially equal in size.

[0087] The valve seat ring 906 can be deployed with any type of slide valve (e.g., ball valve, angle valve, etc.). The valve seat ring 906 can be deployed in various orientations relative to the fluid flow through the fluid flow channel. For example, the valve seat ring 906 can be oriented such that the portion with the largest number of vanes is oriented close to the vortex region (e.g., the second portion 940 is aligned with Figure 1 the fluid vortex 102).

[0088] In some examples, when the valve plug is withdrawn from the sealing contact with the valve seat ring 906, fluid flows through the valve seat ring 906. In some such examples, the fluid is diverted by the vanes 908, 910, 912, 914, 916, 918 of the valve seat ring 906. Guiding the fluid flow by the valve seat ring 906 reduces the generation of turbulence because the flow is directed through the fluid flow channel and away from regions that cause low flow resistance areas (e.g., Figure 1 the cavity 124, Figure 2 the region 224, etc.) that cause turbulence. The use of the valve seat ring 906 reduces the adverse effects associated with vortices (e.g., vibration, reduced flow capacity, etc.).

[0089] Figure 10A FIG. 1000 is a front view example of an example valve seat ring 1006 implemented in accordance with the teachings of the present disclosure, Figure 10B FIG. 1002 is a top view example, Figure 10C FIG. 1004 is a bottom view example. The valve seat ring 1006 includes example first vanes 1008, example second vanes 1010, example third vanes 1012, example fourth vanes 1014, example fifth vanes 1016, and example sixth vanes 1018 that are unevenly distributed around the valve seat ring 1006. In Figure 10A - Figure 10C the example, the unevenly distributed vanes 1008, 1010, 1012, 1014, 1016, 1018 are part of a single body of the valve seat ring 1006 (e.g., the vanes 1008, 1010, 1012, 1014, 1016, 1018 and the valve seat ring body are integral components, etc.). In some such examples, the valve seat ring 1006 can be manufactured via machining (e.g., negative manufacturing), casting, additive manufacturing, and / or any other suitable method. In other examples, some or all of the vanes 1008, 1010, 1012, 1014, 1016, 1018 can be coupled (e.g., via one or more welds, one or more fasteners, chemical adhesives, press fits, shrink fits, etc.) to the valve seat ring 1006. In Figure 10A - Figure 10C the example shown, the vanes 1008, 1010, 1012, 1014, 1016, 1018 of the valve seat ring 1006 have flat walls (e.g., planar walls, etc.).

[0090] The dimensions of an example outer surface 1020 of the valve seat ring 1006 are designed to be suitable for functioning within the body of a valve (e.g., the valve body 108 of the valve 100 such as Figure 1 ). The valve seat ring 1006 is disposed within the fluid flow passage of the valve body such that the path of movement of the valve seat ring 1006 and the valve plug between a sealed position (i.e., the valve plug meets the valve seat ring 1006) and an open position (i.e., the valve plug is withdrawn from the surface of the valve seat ring 1006) is aligned. A portion of the valve body is dimensioned to receive the valve seat ring. In some examples, the valve seat ring 1006 may include threads to secure the valve seat ring 1006 to the valve body. The valve seat ring 1006 has an example first end 1022 and an example second end 1024. Different from the blades 908, 910, 912, 914, 916, 918 that start at the second end 924 Figure 9A - Figure 9C , the blades 1008, 1010, 1012, 1014, 1016, 1018 start near the first end 1022, extend through the body of the valve seat ring 1006, and extend along the stem below the second end 1024. The valve seat ring 1006 can be deployed with any type of sliding stem valve (e.g., ball valve, angle valve, etc.). In some examples, the valve seat ring 906 can be deployed with additional flow disturbance reducing members (e.g., valve plugs 300, 400, 500, 600, etc.).

[0091] In Figure 10A - Figure 10C the example shown, the valve seat ring 1006 includes an example first angle 1026, an example second angle 1028, and an example third angle 1030, an example fourth angle 1032, an example fifth angle 1034, and an example sixth angle 1036. The first angle 1026 is defined by the angular displacement between the first blade 1008 and the second blade 1010. The second angle 1028 is defined by the angular displacement between the second blade 1010 and the third blade 1012. The third angle 1030 is defined by the angular displacement between the third blade 1012 and the fourth blade 1014. The fourth angle 1032 is defined by the angular displacement between the fourth blade 1014 and the fifth blade 1016. The fifth angle 1034 is defined by the angular displacement between the fifth blade 1016 and the sixth blade 1018. The sixth angle 1036 is defined by the angular displacement between the sixth blade 1018 and the first blade 1008.

[0092] In Figure 10A - Figure 10CIn the example shown, the first angle 1026, the second angle 1028, the third angle 1030, and the fourth angle 1032 have the same magnitude, while the fifth angle 1034 and the sixth angle 1036 have different magnitudes. In some examples, the first angle 1026, the second angle 1028, the third angle 1030, the fourth angle 1032, the fifth angle 1034, and the sixth angle 1036 all have different magnitudes, while in other examples, one or more have equal magnitudes. In other examples, if the angles 1026, 1028, 1030, 1032, 1034, 1036 are of equal magnitude, the vanes 1008, 1010, 1012, 1014, 1016, 1018 are circumferentially uniformly distributed around the valve plug.

[0093] In Figure 10A - Figure 10C the example shown, the second end 1024 of the valve seat ring 1006 defines an example first portion 1038 and an example second portion 1040. In Figure 10A - Figure 10C the example, the first portion 1038 includes a first number of circumferentially spaced vanes, and the second portion 1040 includes a second number of circumferentially spaced vanes. In this example, the first portion 1038 extends clockwise between the first vane 1008 and the fifth vane 1016 and includes the sixth vane 1018. The second portion 1040 extends clockwise between the fifth vane 1016 and the first vane 1008 and includes the second vane 1010, the third vane 1012, and the fourth vane 1014. In some examples, the first number of vanes in the first portion 1038 is greater than, less than, or equal to the second number of vanes in the second portion 1040. In other examples, the first portion 1038 and the second portion 1040 are substantially equal in size.

[0094] Similar to Figure 9A - Figure 9C the valve seat ring 906, the valve seat ring 1006 can be deployed with any type of slide valve (e.g., ball valve, angle valve, etc.). And is in various orientations relative to the fluid flow through the fluid flow passage. For example, the valve seat ring 1006 can be oriented such that the portion with the largest number of vanes is oriented close to the vortex region (e.g., the second portion 1040 is aligned with Figure 1 the fluid vortex 102).

[0095] In some examples, when the valve plug is withdrawn from the sealing contact with the valve seat ring 1006, fluid flows through the valve seat ring 1006 and is diverted by the vanes 1008, 1010, 1012, 1014, 1016, 1018, guiding the fluid flow away from the region causing low flow resistance (e.g., Figure 1 the cavity 124, Figure 2Turbulence in regions such as region 224, etc. The use of the valve seat ring 1006 reduces the adverse effects associated with vortices (e.g., vibration, reduced flow capacity, etc.).

[0096] Figure 11A is a front view 1100 of an exemplary valve seat ring 1106 implemented in accordance with the teachings of the present disclosure, Figure 11B is an exemplary top view 1102, Figure 11C is an exemplary bottom view 1104. The valve seat ring 1106 includes exemplary first vanes 1108, exemplary second vanes 1110, exemplary third vanes 1112, exemplary fourth vanes 1114, exemplary fifth vanes 1116, and exemplary sixth vanes 1118 that are unevenly distributed around the valve seat ring 1106. In Figure 11A - Figure 11C an example, the unevenly distributed vanes 1108, 1110, 1112, 1114, 1116, 1118 are part of a single body of the valve seat ring 1106 (e.g., the vanes 1108, 1110, 1112, 1114, 1116, 1118 and the valve seat ring body are integral components, etc.). In some such examples, the valve seat ring 1106 can be manufactured by machining (e.g., subtractive manufacturing), casting, additive manufacturing, and / or any other suitable method. In other examples, some or all of the vanes 1108, 1110, 1112, 1114, 1116, 1118 can be coupled (e.g., via one or more welds, one or more fasteners, chemical adhesives, press fits, shrink fits, etc.) to the valve seat ring 1106. In Figure 11A - Figure 11C the example shown, the vanes 1108, 1110, 1112, 1114, 1116, 1118 of the valve seat ring 1106 have flat walls (e.g., planar walls, etc.).

[0097] The dimensions of an exemplary outer surface 1120 of the valve seat ring 1106 are designed to be suitable for functioning within the body of a valve (e.g., Figure 1 the valve body 108 of valve 100, etc.). The valve seat ring 1106 is disposed within the fluid flow channel of the valve body such that the path of movement of the valve seat ring 1106 between a sealing position (i.e., the valve plug meets the valve seat ring 1106) and an open position (i.e., the valve plug is withdrawn from the surface of the valve seat ring 1106) is aligned with the valve plug. A portion of the valve body is sized to receive the valve seat ring. In some examples, the valve seat ring 1106 can include threads to fasten the valve seat ring 1106 to the valve body. The valve seat ring 1106 has an exemplary first end 1122 and an exemplary second end 1124. Starting at the second end 924 Figure 9A - Figure 9CThe vanes 908, 910, 912, 914, 916, 918 are different. Vanes 1108, 1110, 1112, 1114, 1116, 1118 start above the first end 1122 and extend along the stem through the seat ring 1106 and extend below the seat ring 1106. Additionally, different from Figure 10A - Figure 10C the vanes 1008, 1010, 1012, 1014, 1016, 1018 that start at the first end 1022, vanes 1108, 1110, 1112, 1114, 1116, 1118 start above the first end 1122 of the seat ring 1106 and do not extend as far below the second end 1124 of the seat ring 1106. The seat ring 1106 can be deployed with any type of slide stem valve (e.g., ball valve, angle valve, etc.). In some examples, the seat ring 906 can be deployed with additional flow disturbance reducing members (e.g., valve plugs 300, 400, 500, 600, etc.).

[0098] In [[ the example shown, the seat ring 1106 includes an example first angle 1126, an example second angle 1128, and an example third angle 1130, an example fourth angle 1132, an example fifth angle 1134, and an example sixth angle 1136. The first angle 1126 is defined by the angular displacement between the first vane 1108 and the second vane 1110. The second angle 1128 is defined by the angular displacement between the second vane 1110 and the third vane 1112. The third angle 1130 is defined by the angular displacement between the third vane 1112 and the fourth vane 1114. The fourth angle 1132 is defined by the angular displacement between the fourth vane 1114 and the fifth vane 1116. The fifth angle 1134 is defined by the angular displacement between the fifth vane 1116 and the sixth vane 1118. The sixth angle 1136 is defined by the angular displacement between the sixth vane 1118 and the first vane 1108.

[0099] In ​ the example shown, the first angle 1126, the second angle 1128, the third angle 1130, and the fourth angle 1132 have the same magnitude, while the fifth angle 1134 and the sixth angle 1136 have different magnitudes. In some examples, the first angle 1126, the second angle 1128, the third angle 1130, the fourth angle 1132, the fifth angle 1134, and the sixth angle 1136 all have different magnitudes, and in other examples, one or more have equal magnitudes. In other examples, if the angles 1126, 1128, 1130, 1132, 1134, 1136 are of equal magnitude, then the vanes 1108, 1110, 1112, 1114, 1116, 1118 are circumferentially evenly distributed around the valve plug.

[0100] In ​In the example shown, the second end 1124 of the valve seat ring 1106 defines an example first portion 1138 and an example second portion 1140. In ​ the example of ​ , the first portion 1138 includes a first number of circumferentially spaced-apart vanes, and the second portion 1140 includes a second number of circumferentially spaced-apart vanes. In this example, the first portion 1138 extends clockwise between the first vane 1108 and the fifth vane 1116 and includes the sixth vane 1118. The second portion 1140 extends clockwise between the fifth vane 1116 and the first vane 1108 and includes the second vane 1110, the third vane 1112, and the fourth vane 1114. In some examples, the first number of vanes of the first portion 1138 is greater than, less than, or equal to the second number of vanes of the second portion 1140. In other examples, the first portion 1138 and the second portion 1140 are substantially equal in size.

[0101] The valve seat ring 1106 can be deployed with any type of slide valve (e.g., ball valve, angle valve, etc.). The valve seat ring 1106 can be deployed in various orientations relative to the fluid flow through the fluid flow passage. For example, the valve seat ring 1106 can be oriented such that the portion with the largest number of vanes is oriented near the vortex region (e.g., the second portion 1140 is aligned with ​ the fluid vortex 102).

[0102] In some examples, when the valve plug is withdrawn from sealing contact with the valve seat ring 1106, fluid flows through the valve seat ring 1106. In some such examples, the fluid is diverted by the vanes 1108, 1110, 1112, 1114, 1116, 1118 of the valve seat ring 1106. Directing the fluid flow by the valve seat ring 1106 reduces the generation of turbulence because the flow is directed through the fluid flow passage and away from regions that cause low flow resistance areas (e.g., ​ the cavity 124 of ​ , ​ the region 224 of ​ , etc.) that cause turbulence. The use of the valve seat ring 1106 reduces the adverse effects associated with vortices (e.g., vibration, reduced flow capacity, etc.).

[0103] As can be understood from the foregoing, example systems, methods, devices, and articles for a valve plug with distributed vanes have been disclosed, which direct and distribute fluid flow through the valve while enhancing overall functionality and lifespan. Known fluid valves are affected by turbulence near the valve seat, which can lead to a reduction in flow capacity, adverse mechanical vibrations, and corrosion of essential valve components such as the valve seat and valve plug. Some example methods and devices described herein utilize guiding structures (e.g., a fluid plug and / or seat ring with distributed vanes) to reduce turbulence, thereby increasing valve flow capacity and reducing vibrations. Additionally, some disclosed examples utilize distributed vanes to split the flow into several smaller flows. Further, some disclosed examples utilize grooves between adjacent vanes to direct the separated flows in a desired manner.
