    This patent application claims the benefit of Provisional US Patent Application No. 61/319,342 filed March 31, 2010, and Provisional US Patent Application No. 61/333,517 filed on May 11, 2010. FUNDAMENTALS OF THE INVENTION 1. Field of the Invention
    The present invention relates generally to rotary valves and more particularly to an improved valve stem assembly. 2. Description of Fundamentals
    Larger diameter rotary valves, such as ball valves and plug valves, can typically use trunnions to secure the rotary member within the valve body. In other words, the rotating element is mounted with a trunnion. As an alternative to trunnion mounting of the rotary element, smaller valves may allow the rotary element to float within the valve body. On these smaller valves, a flared end may then be provided on the valve stem to retain the valve stem within the valve body. The flared end of the valve stem secures the valve stem to the valve body, making the stem virtually explosion proof. However, for trunnion mounted rotary elements, the flared end cannot be used because the valve stem and rotary element cannot be inserted into the body due to the presence of the trunnions.
    Therefore, in valves used over the past several decades, trunnion-mounted rotating elements utilize an outer plate to secure the valve stem to the valve body. The plate is screwed onto the valve body.
    The valve stem may then have a flared end, which is larger than the opening in the bolted plate to the valve, but not larger than the opening in the rotary valve through which the stem is used to couple and rotate the element. rotary.
    However, in this type of valve, which has been used for decades, the forces produced by the actuator by the repeated opening and closing of the valves can cause the pins that hold the plate to the body to wear, 10 with the potential that the valve stem can be released from the valve when the valve is under pressure.
    The prior art discussed above does not show a design which is not based on pegs or body fasteners of any kind to retain the valve stem within the pressure area of a valve with a trunnion mounted rotary member. Those skilled in the art will appreciate the present invention that addresses the above needs and other significant needs, the solution of which is discussed below. BRIEF DESCRIPTION OF THE INVENTION

    Various other objectives, features and ancillary advantages of the present invention will become fully appreciated as they become better understood when considered in conjunction with the accompanying drawings, and in that: FIGURE 1 is an exploded perspective view, showing a rotary valve with withdrawn body on the valve stem and split trunnions according to a possible embodiment of the present invention; and FIGURE 2 is a perspective view, partially in section, showing the rotary valve of FIGURE 1 in accordance with one possible embodiment of the present invention.
    While the present invention will be described in connection with preferred embodiments, it will be understood that it is not intended to limit the invention to those embodiments. Rather, it is intended to cover all alternatives, modifications, and equivalents included within the character of the invention and as defined in the appended claims. DESCRIPTION OF PREFERRED ACHIEVEMENTS
    Referring now to the drawings, and more particularly to FIGURE 1 and FIGURE 2, the present invention shows the rotary valve 10, in this case a ball valve 10, which provides a valve stem retained in the body 16 within the valve body 12 .
    The valve body 12 there defines the valve stem opening 14. In one embodiment, the valve stem opening 14 is a straight-sided cylindrical opening.
    However, the valve stem opening 14 could also have other configurations. Valve stem 16 may comprise elongated cylindrical body 18 with flared portion 20 at one end thereof, which may also be cylindrical in shape. The flared portion 20 has a larger diameter than the valve stem opening 14 and therefore is retained within the valve body 12 with the full force of the wall 24 of the valve body 12, and without the need to rely on pegs or pins. fasteners.
    The flared part 20 can be formed in 25 different ways and, in this embodiment, can comprise any component or flared part of the valve stem 16 that couples directly or indirectly to an inner surface of the wall of the valve body 24 or to an inner part of the valve. opening the valve stem 14 to limit radial outward movement 30 of the valve stem 16 and retain the valve stem 16 within the valve body 2. As a different example, the flared end 20 may comprise a thrust bearing or something of the sort that is enlarged in relation to the opening of the valve stem 14.
    In another example, valve stem 16 may comprise a tapered or tapered portion that engages with a tapered or tapered portion of the valve stem opening 14.
    In this way, the valve stem opening 14 and the valve stem 16 are designed in any suitable proportions so that the valve stem 16 has a portion that has a larger diameter than at least a portion of the valve stem opening. 14 so that valve stem 16 is retained within valve body 12.
    During assembly of that embodiment, the elongated cylindrical end 18 of the valve stem 16 is inserted into the inner side of the valve stem opening 14 in the valve body 12. The flared end 20 is then positioned within the interior of the body 22 of the valve body 12, whereby the inner surface of valve body 12 prevents further radial outward movement of valve stem 16. In this way, the thickness of wall 24 of valve body 12 firmly retains valve stem 20 16 into the valve body 12, producing a valve stem retained in the explosion proof body 16. Prior to insertion through the valve stem opening 14, seals, bearings and the like can be used on the valve stem 16. Although There are many possible arrangements of such elements, in this embodiment, the stem pressure washer 68, the upper stem seal 70, and the stem O-ring seals 72 are used. and 68 then couples to the inner surface of wall 24 of valve body 12.
    In this embodiment, to allow assembly of a trunnion mounted rotary valve 10 with the valve stem retained in the body 16, split upper and lower trunnions 26 and 28 are used. The split trunnions comprise separate components 26a, 26b, and 28a, 28b that can be inserted from opposite sides of the valve body 12.
    Depending on the design of the components, the lower trunnion 28 may not have to be split, if desired, 5 due to the absence of the need for a valve stem on the underside. However, at least the upper trunnion 26 is preferably divided so that the upper trunnion 26 can be inserted into the valve body 12 after the rotatable member 30 has been inserted into the valve body 12, and 10 after the valve stem. 16 has been inserted into the valve body.
    As used herein, a trunnion is a support element, which is used to support the upper and lower portions of the rotatable element 30 in the valve body 12 to restrict the movement of the rotatable element 30 to rotational movement without axial movement along the axis. of the flow passage 42 through the rotary valve 2. In other words, the rotary member 30 does not "float" along the axis of the flow passage as in other types of rotary valves 20 discussed above. In this way, the term "support element" or "split support element" can also be used to refer to the upper and/or lower trunnions 26 and 28. which may be of various shapes and which may or may not comprise extensions or protrusions of the rotatable element 30.
    In that embodiment, the upper and lower split trunnions 26 and 28 are provided to secure or support the upper and lower protrusions 32 and 34. The upper and lower protrusions 30 and 32 and 34 may be, but need not be, protruding portions or extensions on the upper and lower sides of the rotatable member 30. In this embodiment, the upper and lower protrusions 32 and 34 comprise cylindrical-shaped extensions with a substantially constant diameter along their length.
    However, it is not necessary for the diameter of the upper and lower protrusions 32 and 34 to be constant, nor is it necessary for the protrusion or extension to be straight-sided. For example, the extension could be rounded where the upper bulge 32 now appears to comprise a straight-sided cylinder. As another example, the upper and lower protrusions may comprise an upper portion of the surface of the rotatable element 30 without an extension.
    Essentially, the upper and lower protrusions 32 and 34 are mounting support regions on the rotatable member 30 which are supported by the upper and lower trunnions so as to be restricted from rotational movement 15 without axial movement along the axial flow passage 42. This contrasts with the floating rotary element of other rotary valves. The upper and lower protrusions 32 and 34 need not be extensions, but may comprise any possible type of pivot region for the rotatable member 30 to be supported for or restricted to the rotational movement of the rotatable member 30 while preventing axial movement along the axis. axial flow passage 42.
    In this embodiment, the upper and lower trunnions 26 and 28 define cylindrical upper and lower 25 coupling openings 36 and 38 which support the upper and lower protrusions 32 and 34 upon rotational movement of the rotatable element 30 within the valve body 12 to open and close the rotary valve 10. The openings or mating surfaces formed in the upper and lower trunnions 26 and 28 30 coupled to the upper and lower protrusions 32 and 34 comprise openings and/or bearing surfaces of any shape which conform to the protrusions. While openings 36 and 38 comprise cylindrical openings of constant diameter and straight sides in this example, as another example, openings 36 and 38 may comprise tapered and/or curved diameter openings.
    The outflow opening 40 through the rotatable member 5 30 can be rotated parallel or perpendicular to the outflow passage 42 to open and close the rotatable valve 10. The outflow passage 42 can be cylindrical and passes axially through the valve 10 when the opening is opened. of flow 40 is open.
    The upper and lower trunnion components 26a,26b and 28a,28b are compressed together within the interior of the body 22 and held in place by the end connectors 44 and 46 to thereby secure the upper and lower protrusions 32 and 34, and that so the movement of the rotatable element 30 is restricted to rotational movement without axial movement along the flow passage 42. In other words, the rotatable element 30 is not a so-called floating rotatable element.
    After valve stem 16 is inserted into valve body 12, rotary member 30 can then be inserted into valve body 12 to lock engagement with valve stem 16. In this embodiment, valve stem 16 comprises a interlocking member which is inserted into coupling groove 48 in upper boss 32 to rotationally affix valve stem 16 to upper boss 32, whereby rotation of valve stem 16 results in corresponding rotation of rotary member 30. However , various types of interlocking members can be used to rotationally affix or lock the valve stem 16 to the upper boss 32 and the interlocking member, and the coupling groove 48 shown is just one example of the same.
    During assembly of rotary valve 10, as indicated in FIGURE 1 and FIGURE 2, end 8 of valve stem 16 is inserted through opening of valve stem 14 from interior 22 of valve body 12. , the flared portion or end 20 or a thrust bearing or the like couples with a wall of the inner surface valve body 24 to prevent the valve stem 16 from being radially expelled out of the rotary valve 10 even when the rotary valve 10 is under high pressure. The rotatable member 30 can then be inserted into the valve body 12, whereby the valve stem 16 interlocks with the notch 48 in the upper protrusion 32 of the rotatable member 30.
    Thereafter, the upper and lower split trunnions 26 and 28 can be inserted on opposite sides of the valve body 12 to allow the rotatable member 30 to be trunnion-mounted. It will be appreciated that the trunnion/protrusion assembly can be of a number of different configurations. In that case, the upper and lower split journals 26 and 28 are generally rectangular when assembled together and comprise curved outer surfaces 49 and 50. When assembled, openings 36 and 38 have an inner diameter slightly than the outer diameter. of the cylindrical protuberances 32 and 34.
    Prior to insertion of rotary member 30 into valve body 12, upper and lower spring washers 52 and 54 can be positioned on upper and lower protrusions 32 and 34. Upper and lower rotary trunnion bearings 56 and 58 can also be positioned at the upper and lower protuberances 32 and 34. The rotatable member 30 can then be tilted during insertion so that the groove 48 can first engage with the valve stem 16 without damaging the upper rotatable bearing 56.
    In this embodiment of rotary valve 10, rotary member 30 is spherical in shape. However, the present invention can be used with any type of rotary valve, such as ball valves, plug valves and the like.
    In that embodiment, a series of primary seals 72 and secondary seals 74 are used to seal between the cylindrical flow passage 42 through the rotary valve 10 and opposite sides of the rotary member 30. However, other seals may also be used to seal the member 10 rotary 30 according to the present invention, if desired.
    End connectors 4 4 and 46 of valve 10 secure the trunnions, seals and other elements within the body of valve 12 with the use of fasteners, screws, 15 bolts, rivets, nuts and/or the like as indicated in 60.
    The valve stem 16 also extends through the opening 62 in the adapter plate 64, which is used and mounted by fasteners, screws, bolts, rivets, nuts and/or the like as indicated at 66. However, the plate adapter 64 is not required to secure the valve stem 16 to the valve body 12. Instead, the valve stem 16 is inserted into the valve body 12 so that the flared portion 20, which in this embodiment is at the end 25, is valve stem 16, retains valve stem 16 within valve body 12 without the need for fasteners. In this embodiment, adapter plate 64 is used to connect an actuator (not shown) to valve body 12.
    During assembly, O-ring seals 73, upper stem seal 70, and spring washer bearing 68 can be positioned on valve stem 16. Spring washers 52, 54 and rotary trunnion bearings 56, 58 are placed on the upper and lower protrusions 32, 34 of the rotatable member 30. If desired, the rotatable member 30 can then be inserted into the valve body 12 at an angle such that the connector on the valve stem 16 engages in the groove 48 or in another interconnecting element in the upper protrusion 32 of the rotatable member 30. With these components in place within the valve body 12, then the upper and lower split trunnions 26, 28 can be inserted around the upper and lower protrusions 32, 34 from from opposite sides of valve body 12. Primary 72 and secondary seal assemblies 74 are installed on opposite sides of rotary member 30 and end connectors 44 and 46 are secured on opposite sides of body d. the valve 12. Then the adapter plate 15 of the actuator 64 can be screwed into place using grub screws 66, or the like.
