Definitions

  • the invention relates to an adjustable regulator insert as featured in the preamble to claim 1.
  • Such regulator insert is known eg from WO 95/12082 showing a regulator insert comprising a housing being at the one end provided with radial inflow openings and at the other end provided with radial and axially extending, slot- shaped outflow openings.
  • the insert is configured with a roller membrane more or less closing off the outflow openings in response to the differential pressure, whereby an essentially constant liquid flow through the insert is accomplished.
  • the roller membrane is influenced by two oppositely oriented forces, viz on the side where the outflow openings are arranged, by the pressure within the insert and a helical spring seeking to keep the outflow openings open, and on the other side, by the pressure immediately outside the inflow openings of the insert; liquid communication being provided there between.
  • the roller membrane In case of a given differential pressure across the insert, the roller membrane will adapt at a state of equilibrium between these forces resulting in a constant liquid flow through the insert.
  • the total area of the inflow openings can be set incrementally in advance to a desired constant liquid flow through the insert.
  • Figure 1 is a cross sectional view of a regulator valve having a regulator insert configured in accordance with the invention
  • Figure 2a shows a regulator insert according to the invention, seen from the side, in a first setting
  • Figure 2b is a cross sectional view of the regulator insert, shown in Figure 2a;
  • Figure 3a shows the a regulator insert according to the invention, seen from the side, in a second setting
  • Figure 3b is a cross sectional view of the regulator insert shown in Figure 2a.
  • Figure 4 is a cross sectional view of the regulator insert shown in Figures 1- 3b in a third position.
  • FIG. 1 is a cross-sectional view of a regulator valve 1 having a regulator insert 2 configured in accordance with the invention.
  • the regulator valve 1 comprises a valve housing 3 typically cast from eg brass.
  • the valve housing 3 comprises an inlet part 4 and an outlet part 5 that are aligned and, via an internal thread (not shown) interconnectable with two pipes in the plant in which the regulator valve 1 is used.
  • the regulator insert 2 - or just the insert 2 - is arranged in a sloping seat in the valve housing 3 and is mounted via cooperating threads between the valve housing 3 and a mounting sleeve 6 in the insert 2, as is commonly known. It is of no significance that the insert 6 is slopingly arranged in the valve housing 3, as it may just as well be arranged differently.
  • the insert 2 comprises a cup-shaped through-flow part 7 with inflow openings 8 and outflow openings 9.
  • the inflow openings 8 can be adjusted steplessly to a desired through-flow across the insert 2 since, internally in the cup-shaped through-flow part 7, a closure skirt 10 is provided which is displaceable in the axial direction.
  • the closure skirt 10 has an interior hub 11 being threadedly engaged with a spindle 12 that extends throughout the entire cup-shaped part 7. When the spindle 12 is rotated as will be described later, the closure skirt 10 is displaced upwards or downwards into the cup-shaped part 7 and thereby increases or reduces the overall area of the inflow openings 8.
  • roller membrane 13 At the outflow openings 9 a roller membrane 13 is provided that more or less closes off the outflow openings 9 in response to the pressure conditions prevailing across and through the insert 2. At its outer peripheral edge, the roller membrane 13 is secured between the mounting sleeve 6 and the cup- shaped part 7, while the internal peripheral edge is secured to a cap 14 arranged freely rotatable and axially displaceable on the spindle 12. A helical spring 15 is arranged between the hub 11 of the closure skirt 7 and the cap 14.
  • the spindle 12 has a central cavity 16 being at the one end in open communication with the inlet part 4 of the valve housing 3 and, at the other end, in open communication with a space 17 above the roller membrane 13.
  • an adjustment device is provided that comprises a central shaft 18 being in rotationally secured engagement with the spindle 12 that extends downwards into the cup-shaped part 7.
  • the central spindle 18 is rotatably journalled in the mounting sleeve 6, and rotation of the shaft 18 entails a rotation of the spindle 12, whereby the closure skirt 10 is displaced upwards or downwards via the cooperating threads on the spindle 12 and the hub 11 of the closure skirt 10.
  • Rotation of the shaft 18 is accomplished by means of a key 28 (shown by broken lines in Figure 4) that fits in such a manner as to be secured against rotation with the exposed end 19 of the shaft 18, said end preferably having a square cross section.
  • the shaft is in a rotationally secured engagement with a sleeve 20 being provided with an external thread.
  • an annular follower 21 is provided externally on the sleeve 20 and in threaded engagement therewith.
  • the indicator pin 22 is arranged to be axially displaceable in a guide 23 in an external jacket 24.
  • a cover cap 25 is, in the shown operating position, mounted above the exposed outer end 19 of the shaft 18, whereby an attractive appearance is accomplished.
  • miscellaneous sealing rings O-rings
  • Such sealing rings are commonly known and will not be subject to further description herein.
  • the pitch of the thread on the sleeve 20 exceeds the pitch of the thread of the spindle 12, which means that the absolute displacement of the closure skirt 10 does not correspond to the absolute displacement of the follower 21.
  • the external scale is easier to read.
  • the setting mechanism is configured such that it is not possible to screw the closure skirt 10 completely home in the cup-shaped par 7, and the risk of damaging the insert 2 in this manner is thereby eliminated.
  • the mechanism will be described with reference to Figure 4, showing the insert in cross section, wherein it is no longer possible to make the key 28 engage with the exposed outer end 19 of the shaft 18. It is noted that the decorative cover cap 25 has been dismounted.
  • the key 28 increasingly loses its engagement with the outer end 19 of the shaft 18 as it is pushed upwards by the bushing 20, until it is no longer able to engage. Thereby a clear indication is given to the user that further rotation of the shaft 18 must not occur. It is possible to carefully seize the protruding part of the sleeve 20 and carefully rotate it in the opposite direction while the shaft is brought along. When the outer end 19 of the shaft 18 is again sufficiently exposed, the key 28 can be used again.
  • the invention was described with reference to a preferred embodiment of a regulator insert. However, the invention also lends itself for use in other types of adjustable regulator inserts, where it is desired to minimise the risk of destroying the regulator insert if the adjustment device is screwed to far in the one direction.

Abstract

La présente invention se rapporte à un insert régulateur réglable (2) pour vannes, destiné en particulier à réguler l'écoulement de liquide dans une installation de chauffage central ou de climatisation. L'insert (2) selon l'invention comprend une partie cupulifome (7) dotée d'ouvertures d'amenée (8) et d'ouvertures de sortie (9), lesdites ouvertures de sortie (9) se fermant en réponse à la différence de pression dans l'insert (2), sous l'effet d'un ressort (15) qui veille à maintenir les ouvertures de sortie (9) ouvertes. En outre, l'insert (2) est doté de moyens permettant de fermer de manière réglable les ouvertures d'amenée (8), lesdits moyens comprenant un arbre (18) qui est rotatif par rapport à une jaquette (24) et possède une extrémité externe (19) qui est exposée par rapport à l'environnement. L'insert (2) comporte également : un manchon non fixe (20) qui est en prise avec l'arbre (18), de manière à ne pas pouvoir tourner mais à pouvoir se déplacer axialement, et qui est doté d'un filetage externe ; et un fouloir (21) doté d'un filetage interne se trouvant en prise avec le filetage externe du manchon (20) et en prise avec la jaquette (24) de manière à ne pas pouvoir tourner mais à pouvoir se déplacer axialement. Lorsque le fouloir (21) atteint une position extrême, il ne peut se déplacer davantage axialement, ce qui permet aux filetages coopérants du manchon (20) et du fouloir (21), respectivement, de provoquer le déplacement axial du manchon (20) vers l'extérieur, sur l'arbre (18), en direction de son extrémité externe exposée (19), jusqu'à ce qu'il ne puisse plus venir en prise avec lui.
