Definitions

  • This invention relates to tight shutoff butterfly valves, and particularly to such valves having a corrosion-resistant resilient liner.
  • the body castings of these prior art valves have been provided with a boss on the body to which is attached an automatic or manual valve actuator.
  • Such cast-body valves are expensive and cumbersome to manufacture, because the casting must ordinarily be inspected visually or by X-ray methods for flaws, the flaws welded, and the body machined on various surfaces with the attendant generation of substantial amounts of scrap metal shavings.
  • the invention comprises a butterfly valve to be installed between pipeline flanges and secured by flange bolts, comprising a cylindrical body ring having a cylindrical bore and a face portion at each end of the body ring; a corrosion-resistant, resilient liner covering the cylindrical bore and integrally projecting radially outwards along the face portions completely around the bore for a limited distance; a shaft rotatable about its longitudinal axis extending through the body ring and the liner transversely to the axis of the body ring; a disk attached to the shaft within the body ring and liner and having a sealing fit with the liner; and at least one face plate, characterised in that the body ring is formed from a section of pipe or tubing; the said at least one face plate is formed from a metal thinner in the axial direction that the portion of the liner projecting over a corresponding face portion of the body ring and has an opening that circumscribes the said liner portion; and the said at least one face plate has a tab that extends radially out
  • the tab on the face plate includes cut-out portions for pipeline flange bolts whereby the valve may be centred between the flanges.
  • each plate has an annular ringlike portion and first and second tab portions.
  • the annular ringlike portion of each face plate has an inner diameter slightly larger than the outer diameter of the face portions of the valve liner, and each plate is thinner in the direction of the valve body ring axis than the face portions of the liner.
  • the tab portions of these plates extend radially outwardly from the body ring and the first tab portion provides means for mounting an actuator, manual or automatic, to the assembled valve.
  • a valve according to this invention is assembled into a pipeline by mounting between two conventional pipe flanges, the flange bolts fitting around the outside of the valve body ring and the face plate tabs extending between two of the bolts.
  • the flange bolts When the flange bolts are tightened, each of the liner face portions is compressed between a side of the body ring and a pipe flange to effect a seal therebetween.
  • the compression of the liner face portions is limited by abutment of the pipe flange against the annular portion of the face plate, to prevent damage to the liner face portion.
  • the tightened flange bolts rigidly clamp the face plates between the pipe flanges and the valve body ring.
  • An actuator mounted on the first tab portions of the face plates is maintained in a fixed position relative to the valve shaft by the immobile face plates.
  • a cylindrical valve body ring 10 made of a rigid material, has a resilient liner 12, a layer of elastomer, vulcanized or bonded to the body ring 10 such that the liner 12 covers the cylindrical bore of the body ring 10 and extends outwardly from the body ring bore to cover a portion of each of the end faces of the body ring 10 to form two annular flange-like liner face portions 13.
  • the valve body ring 10 is adapted to receive a rotary valve shaft 16 transverse to the axis of the body ring 10.
  • valve disk 14 On the valve shaft 16, within the valve body ring 10, is retained a closure member or valve disk 14, which may be made from a metallic material, such as stainless steel or bronze, or a nonmetallic material such as glassfiber reinforced plastic, to be chemically and physically resistant to the fluid which is to flow through the valve.
  • the valve disk 14 has an enlarged portion 15 through which the valve shaft 16 extends.
  • the valve disk 14 is fixedly retained on the valve shaft 16 by taper pin 18 which is inserted into aligned tapered holes 19 in the valve shaft 16 and the enlarged portion 15 of valve disk 14.
  • the two ends of the valve shaft 16 extend through two holes 24, formed diametrically opposite each other through the liner 12 and body ring 10, to the exterior of the valve body ring 10.
  • valve shaft 16 One end of the valve shaft 16 is adapted to engage a rotary valve actuator, for example, by splines 17 shown on valve shaft 16 or by a groove and key (not shown). Within the holes 24 the valve shaft 16 is supported by bearing bushings 22 which may be formed of a low friction fluorocarbon resin.
  • bearing bushings 22 which may be formed of a low friction fluorocarbon resin.
  • the rubber sealing member In conventional tight-shutoff rubber lined valves it is common for the rubber sealing member to be fitted into the valve body. The valve body confines the internal line pressure while the rubber sealing member provides for tight shutoff. Similarly, it has been common to require packing within each aperture in the valve body to prevent leakage of fluid from the interior of the valve to the exterior.
  • the liner 12 is designed to resist line pressure with the body ring 10 acting as a back-up ring to provide structural rigidity. Additionally, the internal diameter of the cylindrical liner 12 of the valve of this invention is sized for an interference fit with the valve disk 14 whereby the resilient elastomer liner 12 sealingly engages the periphery of the valve disk 14 when the disk is rotated to a position transverse to the axis of the body ring 10. An interference fit is also formed between the elastomer liner 12 and the valve shaft 16 which forms a seal to prevent fluid leakage through the holes 24. No separate sealing member has been shown; however, a seal for example, an o-ring, may be used within holes 24 to prevent fluid leakage through the holes 24. The relative physical positions of these valve pieces may be more easily understood by examination of Figure 2 which shows a cross-sectional view of the butterfly valve of this invention taken along the sectional line 2-2 in Figure 1.
  • Each face plate 30 has an annular ring-like portion 31, with an inner diameter slightly larger than the outer diameter of the face portion 13 of valve liner 12, and first and second tab portions 32 and 34.
  • the first tab portions 32 of the face plates 30 extend radially outwardly from the ring-like portion 31 of the face plates 30 and provide a means for mounting an actuator to the assembled valve.
  • FIG. 1 and 2 An example of an actuator mounting means is shown in Figures 1 and 2 wherein the first tab portions 32 of each of the face plates 30 are extended radially outwardly, and parallel one another, from the ring-like portion 31 a short distance where they then are sloped toward one another before bending to form parallel facing planar portions terminating in ears 33 which extend away from one another at about a right angle from the planar area.
  • a second tab portion 34 extends from the ring-like portion 31 of the face plate 30 diametrically opposite the first tab portion 32.
  • the second tab portion 34 of each of the face plates 30 extend radially from the ring-like portions 31 of the face plates 30 and are then bent at about a right angle toward one another to extend, externally of the valve body ring 10, parallel the axis of the valve body ring 10.
  • the two second tab portions 34 approach each other at the exterior of the valve body ring 10 to retain the second end of the valve shaft 16 for reasons of safety. Should the valve shaft 16 fracture in service, the actuator retains one end of the valve shaft 16 within the valve body ring 10 while the second tab portions 34 prevent outwardly longitudinal movement of the second end of valve shaft 16.
  • each face plate 30 is thinner in the direction of the valve body ring 10 axis than the face portions 13 of the valve liner 12. Also, as noted above, the inner diameter of the ring-like portion 31 of face plate 30 is slightly larger than the outer diameter of the face portion 13 of valve liner 12. When the valve is assembled, as shown in Figure 2, a gap 20 is left between the ring-like portion 31 of face plate 30 and the face portion 13 of valve liner 12.
  • FIG. 3 the butterfly valve of Figures 1 and 2 is shown in a sectional view, mounted between conventional pipe flanges 41 which are held together by flange bolts 42. Additionally, an actuator 40 is shown bolted to the ears 33 which extend from the first tab portions 32 of the face plates 30.
  • a manual actuator 40 is shown; however, any rotary valve actuator, manual or automatic, may be used with this valve.
  • the outer diameter of the ring- like portion 31 of face plates 30 is sized so that flange bolts 42 will fit around the outside of face plate 30 with only a small clearance; thus, the flange bolts 42 center the butterfly valve between the pipe flanges 41.
  • the second tab portion 34 of the face plates 30 is sized such that, when the assembled valve is installed in a pipeline by mounting the valve between conventional pipe flanges 41, the second tab portion 34 extends between two of the flange bolts 42.
  • the first tab portions 32 of face plates 30 include cutout portions or holes 35 through which the pipeline flange bolts 42 extend to aid in centering of the valve between the line flanges 41.
  • valve body ring is cut from a section of the pipe or tubing which are inexpensive and readily available rather than requiring a heavier, more expensive casting.
  • a resilient lining is provided within the valve body ring for tight shut-off.
