Definitions

  • the present disclosure generally relates to fluid pressure control devices and, more particularly, to assemblies for sealing between sliding components used in such devices.
  • Fluid pressure control devices such as control valves and regulators, are commonly used to control the flow characteristics of a fluid.
  • a typical device includes a valve body defining an inlet, an outlet, and a fluid flow path extending between the inlet and the outlet.
  • a valve seat is coupled to the valve body and defines an orifice through which the flow path travels.
  • a throttling element such as a plug, is moveable relative to the valve seat thereby to control fluid flow through the orifice.
  • the throttling element is coupled to a stem extending outside the valve body, which in turn is coupled to an actuator for positioning the throttling element relative to the valve seat.
  • Sliding stem fluid control devices often require components for guiding the throttling element assembly with respect to the valve seat.
  • components which guide movement of the throttling element often include guide surfaces that slide against one another.
  • Rubbing and sliding of guide components in fluid control devices may cause material from the valve components to become free due to wear, galling, or other causes.
  • the non-corrosive materials used for some applications are particularly susceptible to galling. Galling and other wear phenomena can cause movement and transfer of component material along the contact path.
  • the loose material may degrade or disrupt sealed engagements within the fluid control device, such as the primary seal between a throttling element and seat, a secondary seal between a throttling element and cage, or a stem packing seal between a stem and packing assembly, to name a few.
  • FIG. 1 is a side elevation view, in cross-section, of a fluid control device having a relief void positioned adjacent the contact surface between a plug and seat;
  • FIG. 2 is an enlarged view of a detail of FIG. 1 illustrating the relief void
  • FIG. 3 is a side elevation view, in cross-section, of a second embodiment of a fluid control device having a relief void positioned between a plug and cage;
  • FIG. 4 is an enlarged view of a detail of FIG. 3 illustrating the relief void
  • FIG. 5 is a side elevation view, in cross-section, of a further embodiment of a fluid control device having a relief void positioned adjacent the stem and packing assembly.
  • a seal assembly for a fluid control device which includes a relief void for reducing the deleterious affects of galling or other wear damage to sealed contact areas within the device.
  • the relief void provides a space into which material, typically metal material, from components in contact may collect, thereby preventing the material from entering areas intended for sealed contact.
  • the relief void may be positioned adjacent the sealed contact area between a plug and valve seat, between a plug and cage, or between a stem and packing assembly. While these exemplary embodiments are described in greater detail below, it will be appreciated that the relief void may be located in other areas within a fluid control device that would benefit from the benefits taught herein.
  • FIGS. 1 and 2 illustrate a sliding-stem, single port, unbalanced plug control valve 10 having a valve body 12 defining an inlet 14 and an outlet 16 , wherein the valve 10 controls fluid flow from the inlet 14 to the outlet 16 .
  • a valve seat 18 is coupled to the valve body 12 and defines an orifice 20 through which the flow path passes.
  • the valve seat 18 is coupled to the valve body 12 by a threaded engagement, however other known coupling methods may be used.
  • An upper portion of the valve seat 18 is formed with a sealing surface 22 , which has a frostoconical shape in the exemplary embodiment.
  • a lower portion of the valve seat 18 is formed with a cylindrical interior surface 24 .
  • a throttling element assembly 26 is inserted through a top port 28 of the valve body to control fluid flow through the valve seat orifice 20 .
  • the throttling element assembly 26 includes a throttling element, such as plug 30 , coupled to a stem 32 .
  • the plug 30 includes a mating surface 34 that is shaped to complement the valve seat sealing surface 22 , so that the mating surface 34 sealingly engages the sealing surface 22 to form a primary seal when the plug 30 is in the closed position, as illustrated in the FIG. 2 .
  • the plug 32 also includes a cylindrical exterior surface 36 sized to slidingly engage the valve seat interior surface 24 .
  • the interior surface 24 of the valve seat 18 and the exterior surface 36 of the plug 30 provide first and second guide surfaces which direct the plug mating surface 34 toward the valve seat sealing surface 22 as the throttling element assembly 26 moves to the closed position.
  • the plug 30 further includes flow characterizing legs 38 extending downwardly from the exterior surface 36 .
  • the legs 38 are shaped to form gaps 40 therebetween, thereby to obtain desired flow characteristics when the throttling element assembly 26 is only partially open, as is well known in the art. It will be appreciated that other types of plugs, with and without flow characterizing legs, may be used without departing from the scope of the present disclosure.
  • the stem 32 extends from a top surface of the plug 30 and through the valve body top port 28 .
  • a free end 42 of the stem 32 is adapted for coupling to an actuator (not shown) which provides a motive force to the throttling element assembly 26 .
  • a bonnet assembly 43 is coupled to the valve body 12 to enclose the top port 28 and to seal with the stem 32 .
  • the bonnet assembly 42 includes a bonnet 44 releasibly coupled to the body 12 , such as by fasteners.
  • the bonnet 44 has an inner bore 48 defining a packing chamber 50 and a neck 52 .
  • the neck 52 may slidingly engage the stem 32 to provide additional guidance to the throttling element assembly 26 during movement, as discussed in greater detail below with reference to the embodiment of FIG. 5 .
  • a packing assembly 54 may be inserted into the packing chamber 50 to seal between the valve stem 32 and the bonnet inner bore 48 to prevent leakage of fluid therethrough.
  • a relief void 56 is formed in the valve seat 18 to reduce the risk of freed material, such as from galling, from entering the primary seal area. As illustrated in FIGS. 1 and 2 , the relief void 56 is formed as a generally annular groove which creates a gap between the plug exterior surface 36 and the valve seat interior surface 24 . The void 56 has a volume sufficient to receive material from the plug 30 , the valve seat 18 , or other component that may be loosened or otherwise transferred during operation of the throttling element assembly 26 .
  • the relief void 56 is positioned between the primary seal formed by the sealing surface 22 and mating surface 34 and the guide surfaces provided by the plug exterior surface 36 and the valve seat interior surface 24 . Accordingly, material freed by galling, wear, or other causes, which will typically originate in the area of the guide surfaces, will collect in the relief void 56 , thereby avoiding disruption of the primary seal. Material deposited in the relief void 56 may be subsequently removed by process fluid flow or may remain in the relief void indefinitely. While the exemplary embodiment shows the relief void 56 positioned immediately adjacent the primary seal, it will be appreciated that the relief void 56 may have other locations, as long as it is proximate either the guide surfaces or the sealing surfaces.
  • valve seat 18 may additionally or alternatively be provided in the plug 30 . Accordingly, the same or similar materials may be used for the valve seat 18 and plug 30 , such as 316 Stainless Steel, 304L Stainless Steel, Stainless Steel Alloy 20, or the like.
  • FIGS. 3 and 4 illustrate an alternative embodiment of the seal assembly incorporated into a valve 110 having a cage-style trim and balanced valve plug.
  • the valve 110 includes a valve body 112 defining an inlet 114 and an outlet 116 , wherein the valve controls fluid flow from the inlet 114 to the outlet 116 .
  • a valve seat 118 is coupled to the body 112 and defines an orifice 120 through which the flow path passes. Again, while the valve seat 118 is illustrated as being coupled to the valve body 112 by a threaded engagement, other known types of couplings may be used.
  • the valve seat 118 includes a sealing surface 122 .
  • a throttling element assembly 126 and a cage 160 are inserted through a top port 128 of the valve body 112 to control fluid flow through the valve seat orifice 120 .
  • the cage 160 includes a flange 162 that is coupled to and substantially closes off the body top port 128 .
  • a cylindrical wall 164 extends downwardly from the flange 162 and has a bottom edge 166 that is spaced from the valve seat 118 when assembled, thereby to allow fluid flow therebetween.
  • the cylindrical wall 164 further defines an interior surface 168 .
  • the cage 160 also includes a boss 170 having a center bore 172 formed therein.
  • the center bore 172 is substantially concentric with the interior surface 168 and defines a packing chamber 150 and a neck 152 .
  • the throttling element assembly 126 includes a throttling element moveable within the fluid flow path.
  • the throttling element such as a plug 130
  • the throttling element is coupled to a stem 132 which extends from a top surface of the plug 130 and through the valve body top portion 128 .
  • a free end 142 of the stem 132 is adapted for coupling to an actuator (not shown) which provides a motive force to the throttling element assembly 126 .
  • a bottom portion of the plug 130 includes a mating surface 134 that is shaped to complement the valve seat sealing surface 122 , so that the mating surface 134 sealingly engages the sealing surface 122 to form a primary seal when the plug 130 is in the closed position.
  • the plug 132 also includes a balance port 133 which allows fluid to flow into an upper chamber 135 defined by the cage 160 and an upper surface of the plug 130 .
  • the plug 130 includes a guide ring 137 defining an exterior surface 136 sized to slidingly engage the cage interior surface 168 .
  • both the guide ring 137 and the cage interior surface 168 are cylindrical to provide first and second guide surfaces adapted to direct the plug mating surface 134 toward the valve seat sealing surface 122 as the throttling element assembly 126 moves the closed position.
  • the plug 130 also includes a seal ring 139 for preventing fluid leakage through a secondary flow path between the cage 160 and plug 130 .
  • the seal ring 139 is also generally cylindrical and defines a second mating surface 141 sized to slidingly engage and seal with the cage interior surface 168 .
  • the seal ring 139 may be formed of a material that adequately seals with the metal cage material while allowing sliding along the cage interior surface 168 . Possible materials include a fluoropolymer resin, such as the TEFLON® product marketed by DuPont, a graphite material, or nitrile rubber.
  • a first relief void 156 is formed in the plug 130 to reduce the risk free material from entering the secondary seal area of contact between the seal ring 139 and the cage interior surface 168 .
  • the relief void 156 is formed by an intermediate recessed portion 158 of the plug 130 .
  • the intermediate recessed portion 158 creates a generally annular groove having a volume sufficient to receive material from either the plug 130 , the cage 160 , or other valve components that may be loosened or otherwise transferred during operation of the throttling element assembly 126 .
  • the first relief void 156 is positioned between the guide ring and the seal ring, however the alternative locations noted above with respect to the embodiment of FIGS. 1 and 2 may also be used.
  • a second relief void 190 may also be provided. As illustrated in FIGS. 3 and 4 , the second relief void 190 is formed by a top portion 192 of the plug 130 having a reduced diameter. As with the first relief void 156 , the second relief void 190 creates a gap between the plug 130 and the cage interior surface 168 which may receive material freed by galling, wear, or other causes.
  • FIG. 5 shows an enlarged elevation view, in cross-section, of a sealed contact between a packing assembly 210 and a stem 211 .
  • the stem 211 is part of a throttling element assembly including a throttling element (not shown).
  • a bonnet 212 which may be coupled to a valve body (not shown), includes a center bore 214 sized to receive the valve stem 211 .
  • the center bore 214 defines a packing chamber 218 , a neck 220 , and a receptacle 222 .
  • the packing assembly 210 may be inserted into the packing chamber 218 to seal between the valve stem 211 and the inner bore 214 , thereby to prevent leakage of fluid therebetween.
  • the illustrated packing assembly 210 includes a V-ring 230 , a male adaptor 232 , a female adaptor 234 , upper and lower anti-extrusion rings 236 , and a packing box ring 238 , however, other known packing box components may be used without departing from the present disclosure.
  • the packing assembly 210 is compressed so that an interior mating surface 240 of the V ring 230 sealingly engages an exterior sealing surface 242 of the stem 211 .
  • Material for the V ring 230 is selected so that it provides a good seal with the stem while allowing the stem to slide.
  • a bearing ring 246 is inserted into the receptacle 222 for further guiding the stem 211 during travel.
  • the bearing ring 246 includes an interior surface 248 that closely fits an exterior surface of the stem 211 , yet allows the stem to slide. Accordingly, the interior surface 248 and stem exterior surface provide guide surfaces for directing sliding movement of the throttling element assembly.
  • a relief void 250 is formed adjacent the interior surface 248 for receiving loosened material, thereby reducing the risk of degrading the packing assembly/stem seal.
  • the relief void 250 is formed as an enlarged diameter portion of the interior surface 248 , which creates an annular groove.
  • the groove defines a gap between the bearing ring interior surface 248 and the stem exterior surface having a volume sufficient to receive valve material loosened during operation.
  • the relief void 250 is positioned immediately adjacent the guiding surfaces defined by the bearing ring interior surface 248 and the stem exterior surface, which are slightly spaced from the sealed contact between the packing assembly and stem.
