Description
- The present disclosure relates generally to fluid flow control devices. More particularly, embodiments of the present disclosure relate to devices configured to reduce a pressure and energy of a fluid passing therethrough.
- In many areas of industry, it is often necessary to reduce the pressure and energy of fluids (both liquids and gases) within a pipeline or valve. One or more control devices may be employed for this purpose. Various designs for control devices have been presented in the art. For example, a device may be employed to divide the flow through the device into a plurality of separate streams configured as a plurality of tortuous fluid flow paths within the device. As fluid passes through the tortuous fluid flow paths, the fluid changes direction many times. Furthermore, as the fluid travels through the tortuous fluid flow paths, the overall cross-sectional area of the fluid flow path may increase to provide a decrease in the velocity of the fluid within the flow path. The fluid pressure and energy of the fluid is partially dissipated along such paths as a result of losses caused by friction between walls of the path, rapid changes in fluid direction and expansion or contraction chambers. These devices may include what are commonly referred to as “tortuous path trim devices.”
- A fluid flow control device is often provided within a body of a valve, such as a control valve, having a body that is conventionally configured to direct the fluid from an inlet towards the hollow, cylindrical fluid flow control device. The valve may also be configured to direct fluid passing through the fluid flow control device to the exterior thereof towards a fluid outlet. The valve may include a piston, ball, disk, or other device configured to be inserted into a central region of the valve to interrupt fluid flow through the valve and to close the valve.
- Pressurized fluids contain stored mechanical potential energy. A fluid flow control device dissipates this energy by reducing the pressure and velocity of the fluid. As the fluid flows through the fluid pathways, the fluid flow may be turbulent. Turbulent fluid has associated pressure and velocity fluctuations that act upon the structural elements of the pipes and fluid control devices in which the fluid is flowing. These pressure and velocity fluctuations are generally accompanied by other problems such as erosion, noise, vibration, and cavitation. In many applications, these accompanying problems are undesirable or unacceptable characteristics of a fluid flow control device. Conventional fluid flow control devices have not adequately limited problems associated with pressure and velocity fluctuations associated with fluids.
- Various embodiments of the present disclosure comprise fluid flow control devices that overcome many of the problems of conventional fluid flow control devices. The present disclosure describes embodiments of flow control devices that include fluid paths configured to better control cavitation, vibration, and other problems associated with fluid flow control.
- In one or more embodiments, a fluid flow control device may comprise a substantially cylindrical body that extends along a longitudinal axis and that has a sidewall. The cylindrical body may include at least one first channel extending longitudinally along the sidewall and at least one second channel extending longitudinally along the sidewall. At least a portion of one of the at least one first channel and the at least one second channel extends longitudinally at an oblique angle with respect to the longitudinal axis to form a pattern of channels for improving the flow characteristics of a fluid through the channels.
- In a further embodiment, the at least one first channel and the at least one second channel extend at least substantially longitudinally from a first end of the cylindrical body to a second end of the cylindrical body. In a further embodiment, the at least one first channel and the at least one second channel intersect. In yet a further embodiment, the cylindrical body is a first cylindrical body, and the fluid flow control device may further comprise a second cylindrical body concentrically situated in an interior cylindrical cavity of the first cylindrical body. In other embodiments, one or more additional cylindrical bodies may each be concentrically situated in an interior cylindrical cavity of another cylindrical body. In one embodiment, the first cylindrical body and the second cylindrical body each have a curved sidewall such that the first cylindrical body and the second cylindrical body form a substantially spherical ball valve.
- In further embodiments of the flow control device, the at least one first channel intersects a plurality of other channels. In one embodiment, the at least one first channel and at least one second channel may be configured in a cavitation pattern to control cavitation of a substance passing through the first channel and the second channel. For example, the least one first channel and the at least one second channel may form an offset brick pattern on the sidewall, or the at least one first channel and the at least one second channel form a diamond pattern on the sidewall. In a further embodiment, at least one of the at least one first channel and the at least one second channel extends longitudinally along the sidewall in a zigzag pattern. In a further embodiment, the at least one first channel and at least one second channel do not intersect.
- In various embodiments, the channels may be configured in various shapes and sizes. In one embodiment, at least one of the first channel and second channel has a rounded interior surface. In another embodiment, at least one of the first channel and second channel has a squared interior surface having two wall surfaces formed substantially orthogonal to a bottom surface. In yet another embodiment, at least one of the first channel and second channel has an angled interior surface comprising two wall surfaces intersecting at an angle. In a particular embodiment, at least one of the first channel and the second channel has a varying depth with respect to a surface of the sidewall. In a further embodiment, at least one of the first channel and the second channel has a varying width along the longitudinal axis. In another embodiment, the cylindrical body is configured as a plug, and the fluid flow control device further comprises a seat ring situated around the plug.
- Additional embodiments include methods for forming a fluid flow control device. In one or more embodiments of such methods, the methods include forming at least one first groove in a surface of at least one substantially cylindrical body, the at least one first groove extending longitudinally along the at least one substantially cylindrical body; and forming at least one second groove in the surface of the at least one substantially cylindrical body, wherein at least a portion of one of the at least one first groove and the at least one second groove extends longitudinally at an oblique angle with respect to the longitudinal axis. The methods, in some embodiments, may further include combining a plurality of substantially cylindrical bodies into a concentric assembly.

pattern 114 ofchannels cylindrical body 102 to act as a pressure reducing element for control valves as well as to provide associated downstream elements. The geometry of thechannels cylindrical body 102 may be combined with additional cylindrical bodies (seeFIG. 3 ) in a concentric manner to form a concentric assembly that controls the flow of fluid therethrough. In further embodiments, the cylindrical bodies of a concentric assembly may be configured into a ball or sphere shape to enable the formation of spherical flow control elements, such as ball valves, globe valves, and the like. In other embodiments, acylindrical body 102 may be used as downstream blow down and choke tube elements. As a downstream element, concentric assemblies of cylindrical bodies may be used to produce the pressure drop control either in an on/off configuration or in conjunction with a throttling element upstream that could include a valve, manifold, or plug either in a linear or rotary fashion. In this manner, the fluidflow control device 100 may be implemented to provide desired fluid flow control characteristics. - In the embodiment depicted in
FIG. 1 , afirst channel 104 extends longitudinally along thesidewall 112 of thecylindrical body 102. Channels may also be referred to herein as grooves. As depicted, thefirst channel 104 extends longitudinally at an oblique angle with respect to thelongitudinal axis 103 of thecylindrical body 102. This results in the channel spiraling around the exterior surface of thecylindrical body 112. Asecond channel 106, may similarly extend longitudinally at an oblique angle with respect to thelongitudinal axis 103 of the cylindrical body. Thesecond channel 106 may be configured to extend at an angle opposite the angle of thefirst channel 106. In the depicted embodiment, athird channel 108 and afourth channel 110 are also implemented. However, the number of channels and the configuration of channels along thesidewall 112 may vary with each desired application. In the depicted embodiment, thefirst channel 104,second channel 106,third channel 108, andfourth channel 110 intersect one another as they extend around thecylindrical body 102. - The combination of channel paths and channel intersections forms the
pattern 114 on thesidewall 112. Thepattern 114 ofchannels channels pattern 114 of channels may be defined to reduce the cavitations of a liquid passing therethrough. In the depicted embodiment, a diamond pattern is formed on thesidewall 112 of thecylindrical body 102. In further embodiments, other patterns are contemplated, including offset brick patterns, grid patterns, zigzag patterns, and the like. Furthermore, thepattern 114 may be configured to have constant separation such that channel spacing remains constant along the length of thecylindrical body 102, or it may be configured, in some embodiments, to have an expanding separation such that channel spacing changes or varies along the length of thecylindrical body 102. - In some embodiments, the
channels cylindrical body 102. Infurther embodiments channels cylindrical body 102. In at least one embodiment, thecylindrical body 102 may be formed with an interiorcylindrical cavity 116. The interiorcylindrical cavity 116 may be configured to house additional cylindrical bodies therein to form a concentric assembly of cylindrical bodies with a plurality of channels extending therethrough. - The
cylindrical body 102 may be formed using materials such as ceramics, metals, and plastics. Of course, it is contemplated that other materials may be used as well, depending on the application. In at least one embodiment, thecylindrical body 102 may be manufactured by forming thechannels cylindrical body 102 may be formed into a cylinder and thechannels sidewall 112 of the cylinder through a means such as machining. -
FIG. 2 depicts one embodiment of thecylindrical body 102 formed as aplug 202 and inserted into aseat ring 204. As depicted, a plurality ofchannels 206 is formed along the length of theplug 202. Theexterior sidewall 208 of the plug may be situated in contact with theinterior wall 210 of theseat ring 204. In the depicted embodiment, thechannels 206 extend only partially along the length of theplug 202. This enables theplug 202 to prevent the flow of fluid between theexterior sidewall 208 of theplug 202 and theinterior wall 210 of theseat ring 204 when theplug 202 is fully inserted into the seat ring 204 (not depicted). Conversely, when theplug 202 is partially unseated from theseat ring 204, thechannels 206 provide a path for a fluid to flow between theexterior sidewall 208 of theplug 202 and theinterior wall 210 of theseat ring 204. As noted, the pattern formed by thechannels 206 provides improved cavitation characteristics and may be used to reduce turbulence, shear, and fluid velocity. In the depicted embodiment, a diamond pattern is used. - The
plug 202 andseat ring 204 may be used, in one embodiment, to provide single path multi-stage pressure drop control that could be throttled. This could be used independently in combination with, for example, a stacked disk retainer as discussed in U.S. patent application Ser. No. 12/473,007, which is incorporated herein by reference in its entirety. - In a further embodiment, the flow control device may be incorporated into a valve assembly. The valve assembly, which may also be characterized as a control valve, may include a valve body defining a fluid inlet and a fluid outlet, which in use may be connected to pipes that transport fluid to and from the valve assembly. A plug chamber may be positioned between the inlet and the outlet, and a plug head may be disposed therein. The plug head may be coupled to a shaft and may be configured to move within the plug chamber between a fully open position and a closed position. In the open position, the plug head can be refracted to provide fluid communication between the fluid inlet and the fluid outlet, allowing fluid to flow from the fluid inlet to the plug chamber and into the fluid outlet. In the closed position, the plug head is in abutment with a valve seat, forming a seal that physically interrupts fluid communication between the fluid inlet and the fluid outlet, and effectively blocks fluid flow through the valve body.
- The shaft may include an actuator controllably coupled thereto and configured to control the position of the plug head. The actuator may comprise any suitable actuator known to those of ordinary skill in the art. In addition, a positioner may be operably coupled to the actuator. The positioner may comprise any conventional positioner suitable for use with the selected actuator as is known to those of ordinary skill in the art.
