  • FIG. 1 of the drawings there is provided some of the components for use in assembling a valve member in accordance with the invention, the pre-assembled valve member being designated by reference numeral 10’ as shown in FIG. 1 of the drawings.
  • the pre-assembled valve member 10’ comprises a first hemispherical hollow member 12 defining a first annular opening 14 and a second annular opening 16 defined by a first annular edge 18 of the first hemispherical member 12, wherein the second annular opening 16 is larger than the first annular opening 14.
  • the pre-assembled valve member 10’ further comprises a second hemispherical hollow member 20 that is a mirror image of (i.e. symmetrical to) the first hemispherical member 12.
  • the second hemispherical hollow member 20 defines a third annular opening 22 and a fourth annular opening 24 that is defined by a second annular edge 26 of the second hemispherical member 20, wherein the fourth annular opening 24 is larger in diameter than the third annular opening 22.
  • the first and second hemispherical hollow members 12, 20 may be constructed from a metal alloy, preferably a titanium alloy of the type used in the manufacture of golf head clubs.
  • a reinforcement arrangement comprising a first reinforcement means 28 is provided.
  • the first reinforcement means 28 is an elongate stainless steel conduit that has a first end 30 and a second opposite end 32 and defines a bore 42.
  • the conduit 28 extends between the first and third annular openings 14, 22 and the ends 30, 32 thereof are bonded to the first and third annular openings 14, 22 as will be described below.
  • the method comprises abutting the first annular edge 18 of the first hemispherical member 12 against the second annular edge 26 of the second hemispherical hollow member 20, so as to have the first annular opening 14 of the first hemispherical member 14 aligned with, or being in register with, the third annular opening 22 of the second hemispherical member 20.
  • the method comprises sealingly fitting, typically by bonding, for example by welding, more preferably by argon welding, the first hemispherical member 12 to the second hemispherical hollow member 20 along the first and second annular edges 18, 26 as shown by the weld 34 in Figure 2, so as to define a substantially spherical hollow valve body 36.
  • the method further comprises inserting the conduit 28 into the hollow body 36 via, for example, the first annular opening 14, followed by joining, preferably welding, more preferably argon welding, the circumference of the conduit 28 at or proximate the first and second ends 30, 32 of the conduit 28 to walls 38, 40 of the hollow body 36 which define the first annular opening 14 and third annular opening 22, as can be seen in Figures 2 and 3 of the drawings, so as to form a partially reinforced valve member 10 in accordance with the invention.
  • the outer surface of the conduit 28 at the first ends 30 thereof is sealingly fitted to the wall 40 of the hollow valve body 36, as shown by the weld 44.
  • the welded conduit 28 extends between the first annular opening 14 and third annular opening 22 of the substantially spherical hollow valve body 36.
  • the conduit 28 defines a bore 42 which defines a fluid passageway of the valve member 10.
  • valve member 10 as shown in Figures 2 and 3, incorporates the first reinforcing member 28 that acts to strengthen the substantially spherical hollow body 36.
  • valve members such as those depicted in Figure 2
  • valve members are prone to warp when exposed to high fluid pressures in pipelines - which would then compromise the sealing quality of the valves in which the valve members 10 are fitted.
  • the other problem with such a valve member 10, as shown in Figure 2 is that it can only be manufactured up to a predetermined size for it to be acceptable in practice. Therefore, the size of the valve member 10 limits its application in practice.
  • larger hollow valve members 10 are usually not accepted in practice and are never used due to the susceptibility to failure, particularly in high pressure fluid conditions.
  • the reinforcement arrangement in accordance with the invention comprises a second reinforcement means 51 , typically a curable flowable material, such as a fluid which, as shown in Figure 4, is contained in a reservoir 50.
  • the second reinforcement means 51 is arranged to at least partly fill an interior space 37 defined by the conduit 28 and the hollow valve body 36, and is allowed to cure within the interior space 37 so as to strengthen or further reinforce the valve member.
  • the invention therefore extends to an exemplary method of introducing the second reinforcement means into the valve member 10 described above, so as to form a substantially completely reinforced valve member 100, as shown in Figure 5.
  • the method includes forming a first opening 52 and a second spaced apart opening 54 on the first, hollow hemispherical member 12, as shown in Figure 4.
  • the method includes introducing a predetermined amount of the flowable, second reinforcement means 51 through the first opening 52 into the space 37.
  • the second reinforcement means 51 may be a resin, polyurethane or any other suitable filler material, which will preferably not cause the valve body 36 to expand or contract while the flowable second reinforcement means 51 is introduced into the space 37, and also while it cures/solidifies/hardens inside the valve body 36.
  • air/gases are arranged to escape through the second opening 54.
  • the second reinforcement means 51 is introduced into the body 36 until it either partly or fully occupies the space 37, according to the overall strength required for the valve member 100.
  • the first and second openings 52, 54 are sealed, preferably by means of an argon weld 56, so as to trap the second reinforcement means 51 within the valve body 36, as shown in Figure 5.
  • the second reinforcement means 51 may be allowed to cure under ambient temperature conditions or may be caused to cure, for example by placing the valve body 36 containing the second reinforcement means 51 in a cold environment.
  • the overall method in accordance with the invention results in the formation of either a valve member 10 as shown in Figure 2, or the valve member 100 as shown in Figure 5.
  • first reinforcement means 28 is shown as a conduit, it is envisaged that the first reinforcement means may comprise other reinforcement members (not shown) which could be fitted across the first and second hemispherical hollow members 12, 20 to increase the rigidity and strength of the hollow body 36 of the valve member 10.
  • the filler material used or referred to hereinbefore as the second reinforcement means can be substituted with other suitable reinforcement members which can be fitted to the hollow members before or after assembling the symmetrical hollow valve members 12, 20 into the hollow valve body 36.
  • valve member 100 shown in Figure 5 can be used in high fluid pressure applications, and the filler material (i.e. second reinforcement means introduced therein) increases the weight of the valve member 100 making it a desirable product for end users.
  • the valve member 100 in accordance with the present invention can have varying sizes and does not warp during service.
