Definitions

  • the parts of the body 32, 33 cooperate to define a volume adapted to receive the valve member 38 when the valve 30 is open.
  • the valve member-receiving volume may be relatively shallow, and only slightly deeper than the thickness of the valve member 38.
  • the outer face of the body 44 which defines the inner wall of the valve member-receiving volume is substantially part-spherical.
  • the wall of the body 46 may be relatively thick in this area.
  • the thicker portions of the body wall 46 offer increased resistance to failure or deformation due to exposure to elevated internal pressure, and furthermore the thicker portions 46 serve to reinforce and support the adjacent, thinner wall portion 48.

Abstract

L'invention concerne une vanne de fond (10) comprenant un corps (12) définissant un trou traversant (14) et un siège de vanne (16, 17), et un élément de vanne (18) monté dans le corps et déplaçable entre des positions d'ouverture et de fermeture du trou (14). L'élément de vanne (18) définit un segment d'une paroi d'une sphère creuse. L'élément de vanne (18) est disposé, en position d'ouverture, sur un côté du trou (14) et, en position de fermeture, vient en contact avec le siège de vanne (16, 17).
