Definitions

  • the invention relates generally to valves and more particularly to rotatable valves having a free floating valve member pro ⁇ vided with a sealing face shaped as a more or less complete surface of a solid of revolution.
  • the metal to metal sealing is established through a final translatory movement without any friction on the seat or sealing face.
  • the valve remains closed under the most severe conditions like very high pressures and temperatures.
  • the valve, and so its shutoff function is only collapsing when the mechanical and temperature limits of the applied materials are not respected.
  • Fluid shutoff valves are selected for tight sealing characteris ⁇ tics to minimize fluid leakage. Fluid control valves are selected to precisely control dynamic fluid flows characteristics like flow rate or pressure. Both solutions are mostly contradictory and lead many times to double solutions.E.g.in case of highly corrosive proces media a globe valve for throttling and a plug valve for shuttoff purpo- ses are installed.
  • shutoff and throttling The classical ball valve with two seats offers both facilities: shutoff and throttling.
  • the sealing rings are fricti ⁇ onally held onto the ball surface and thus constitute its limi ⁇ tations, whether soft sealing or metallic sealing is used.
  • Conventional soft sealing The limits to the use of soft seals in shut-off valves are essentially defined by the application conditions,namely extreme temperature and pressure, but also by the properties of the media themselves.
  • ball valves are equipped with sealing elements consisting of polymers.
  • the PTFE grades can be looked upon as being standard materials but are limited by natural boundries, like the combinations of diameters and operating pressures and temperatures.
  • the main aim of the present invention is to provide a valve system where a certain rotation of a spindle, e.g. 90 or 101 or 180 degrees, forces a valve member to rotate from a fully open position right in front of a seat whilst the sealing surface on the valve member is axially aligned with the cen- tral seat-face axis(being the flow system axis in most cases) and then with a translatory movement is linearly placed on the seat and after this "seating" is pressurized with a desired and preset closing pressure.
  • a certain rotation of a spindle e.g. 90 or 101 or 180 degrees
  • Angle of rot. Angle of rotation for rotation for
  • any desired closing pressure can be installed, which is reduced to zero before lifting the valve.
  • a valve member with a diametric and/or an axial throughbore is given a certain freedom of rotation and/or translation in a cylindrical housing .
  • the valve member is suspended to a rotating spindle with a pretensioned spring mechanism.
  • the spindle is provided with one or more eccentric circular or non-circular surfaces which act directly or indirectly through frictional forces upon the springmechanism which on its turn is integrated in the valve member and activates the valve member.
  • the spindle is axially guided through the center of the valve , it is provided with a diametric throughbore with the same diameters as the supply conducts in the valve housing ;when the spindle is constructed outside and around the valve member, no throughbore is needed.
  • the dynamic behaviour of the valve system is determined by: - the rotation axis of the spindle with eccentric parts
  • OPENING the valve means a reverse spindle rotation.
  • a strong eccenter-force pulls the valve member of its seat and the whole valve-system starts rota ⁇ ting around the spindle axis into its fully open position.
  • Eventual small positional deflections are stretched out in the last degrees of rotation.
  • the guiding pins force the valve member in a fully aligned position with the flow-axis and the eventual resulting small deviations, radial or translatory, are absorbed by the springsystem and/or the slots.
  • Fig.-l is a cross-sectional view of a rotating valve in accordance with the teachings of the invention in a fully open position.

  • Axis V translated over 0,5 mm.
  • FIG. 1 shows a first preferred embodiment of the new valve system.

  • the cylindrical eccentric part 5 of the spindle is travelling inside circular cavity Rl at the same time supporting it with radial and tangential flexibility by means of a pretensioned spring 4 ; spindle eccenter 5 is frictionally held and pressed to the inner wall Rl of the valve member by said spring 5.
  • the geometric relation ⁇ ship between housing conducts (x) , the diametric throughbore (y) in the valve member and the diametric throughbore (z) in the spindle is such that all throughbores are axially aligned in the sense of the flow direction and so providing an ideal flow path.

  • Fig-7 shows clearly that valve body 3 has no ball shape. Only the sealing surface is here of a spherical implicanas.
  • Fig-8-9-10 show an embodiment where all rotation axes H-S-V-C and the eccenter have a different location. Also is shown in fig-8 a special embodiment where the valve member axis-V is rotated over an angle of 72 degrees (from 90 to 18 degrees) using the two crossings with the flow axis-F for the beginning and the end of the valve member rotation.
  • an infinite variety of angle-combina ⁇ tions is possible between spindle and valve member, although in a practical sense, this number is limited by common practice in industry.
  • a flow chart is made from the valve according fig-11-12 , in fig-13, to give an impression of the relative angle movements of spindle and valve member in relation to the housing.
  • valve system as described is most applicable for all flow shutoff and flow control functions, liquid or gas.
  • the limits of the valve system are only set by the level of modern valve technology in industry.

Abstract

L'obturateur (3) a une liberté limitée de rotation ou de translation, ou les deux, dans un plan perpendiculaire aux axes du système et autour du système à tige (5). Un ressort sous tension (4) est placé entre l'obturateur (3) et l'excentrique de tige (5). Une course de fermeture complète de la tige (5') force l'obturateur successivement à tourner, faire une translation l'amenant sur le siège et subir une pression suivant la formule d'angles figurant dans le tableau (OB = obturateur). Dans des limites pratiques, on peut donner n'importe quelle valeur aux quatre angles. Des broches de guidage (6), qui passent dans des encoches des parois latérales du corps (1), arrêtent la rotation de l'obturateur (3) quand sa face d'étanchéité est alignée avec l'axe central du siège et maintiennent alors le mouvement de translation de la face d'étanchéité sphérique jusque sur le siège. La poursuite de la rotation de la tige met sous pression l'obturateur à sa valeur préréglée. L'ouverture de l'appareil de robinetterie se fait dans l'ordre inverse.
