Definitions

  • This invention relates generally to valves such as faucet valves, and more particularly to improvements in sealing off of flow through a faucet when foreign material or particles reside at sealing surfaces.
  • the improved faucet valve includes: a) a valve chamber, having a flow inlet and a flow outlet, b) a valve operator outside the chamber, c) a stopper in the chamber and operatively connected with the operator, as for example a handle, for movement toward and away from seat structure in the chamber, to control flow from the valve via said outlet, d) and the seat structure including first and second seats, the stopper located to seat on the first seat. e) there being a flexible sealing lip carried by the stopper to sealingly engage the second seat when the stopper seats on the first seat.
  • the lip typically tapers toward an annular edge that flexes when engaging the second seat.
  • the lip is typically configured with taper to seal off against said second seat and also to asymmetrically flex and seal off against or about a foreign element on the second seat.
  • a further object is to provide telescopically interfitting parts, which are relatively movable, one part connected to the handle, and the other part carrying the stopper and such parts typically being tubular.
  • the one part has threaded connection to the chamber, for advancing that one part toward the seat, in response to handle rotation.
  • Said one part may define a drain port to drain fluid from the interior of said one tubular part in which the other part projects.
  • Yet another object includes provision of a compression spring within the interior of said one part, the spring acting to urge said other part toward the seat.
  • the spring may be configured and located to cushion engagement of the stopper by said one part, and via the other part, as the handle is rotated.
  • a further object is to provide passages in the relatively movable parts to supply exterior air to flow past the stopper via said lip, in closed position of the stopper, with the lip engaging a fouling element.
  • Fig. 1 is a view taken in section through a faucet valve in closed, i.e. OFF condition
  • Fig. 2 is a view like Fig. 1, but showing the valve in open, i.e. ON condition;
  • Fig. 3 is a view of the Fig. 2 valve, in a back siphonage condition, with exterior air flowing past the closed stopper via the lip engaging a fouling particle;
  • Fig. 4 is a view like Fig. 3, showing liquid flow through drain passages to the exterior, with the stopper in closed condition;
  • Fig. 5 is a view of the valve stopper and seats in detail, during closed condition
  • Fig. 6 is a view like Fig. 5, showing lip sealing during particle fouling;
  • Fig. 6a is an elevation on lines 6a-6a of Fig. 6: and
  • Fig. 7 is an axial section taken through a stopper, showing typical dimensions.
  • the structure shown in combination includes: a) a valve chamber 10 having a flow inlet 11 from a liquid supply 12, and a flow outlet 13; b) a valve operator 14, such as a rotary handle 15, outside the chamber; c) a stopper 16 in the chamber and operatively connected, at 17, with the operator 14, for movement toward and away from seat structure 18 in the chamber, to control flow from the valve via the outlet; d) the seat structure including first and second seats, 21 and 22, the stopper located to seat on or against the first seat 21 in closed position as shown; e) the stopper carrying a flexible lip 20 to sealingly engage the second seat when the stopper forcibly seats on the first seat.
  • the lip 20 is annular, and extends about a stopper annular surface 24 that engages the annular first seat 21 at 24a.
  • Seat 21 may project above the level of seat 22, and into a pocket or recess 26 formed by surface 24, lip 20 and an annular shoulder 27 defined by the stopper 16.
  • Pocket 26 radially spaces lip sealing at 20a from load or forcible seating at 24a, to make sure that the lip 20 does not engage the projecting seat 24a, which would interfere with lip function.
  • the lip tapers radially outwardly, and axially, at 20b, toward an annular edge 20c that flexes when engaging the second seat, and to controlled extent determined by axial positioning of seating at 24a.
  • the lip is configured with axial and radial tapered elongation or dimensioning not only to seal off against the second seat 22, but also to asymmetrically and locally flex and seal off against a foreign particle or particles 30 that may lodge at a locus between 22 and 24, as seen in Figs. 6 and 6a disturbing sealing at locus 24a. In that event, the lip assures sealing as seen in Fig. 6a with lip flexing and sealing against the second seat and about the foreign particle. This prevents liquid at the downstream side 40 of the stopper from being siphoned back to the liquid supply side at 41 and 41a. Under those conditions as seen in Fig. 3, air is admitted to the valve downstream side 40 and flows past the lip seal, to break the back siphoning effect. See air flow arrows 42, and no downstream liquid at 40, in Fig. 3, is siphoned back into the supply side 41 and 41a, even if the valve is fouled as by a foreign particle or particles, as referred to.
  • That structure includes axially telescopically interfitting parts 35 and 36 which are relatively movable, axially, one part 35 connected to handle 15, and the other part 36 connected to the stopper.
  • tubular part 35 is typically thread connected at 38 to the valve body 39 attached at 48 to the chamber 10 that contains the stopper.
  • part 35 advances from retracted position as seen in Fig. 2 (valve open position) toward the interior 10a of the chamber, as seen in Fig. 1, and relative to part 36, to close the stopper toward the seats as referred to.
  • Fig. 1 represents closed, i.e. OFF condition of the valve, as also seen in Fig.
  • a bevel surface 35a on the lower end of a part 35 sealingly engages an O-ring seal 61 on part 36, near the stopper, to close off communication of fluid pressure in downstream chamber interior 10a to a side wall port 63 in tubular part or stem 36, and to a drain port 65 in the wall 36b of part 36.
  • Fig. 2 ON configuration of the valve, the part 35 is fully retracted by the control handle, and the pressure of flowing supply liquid is exerted on the stopper to push it and part 36 bodily away from the seats, allowing flow through the valve as indicated by arrows 70 in Fig. 2.
  • Supply liquid pressure exertion on the stopper pushes the seal 61 against the bevel surface 60, blocking escape of liquid via ports 63 and 65.
  • Fig. 4 shows the condition that suction exists at the supply side 41 of the stopper, back pressure at interior 10a then being relieved via ports 63 and 65, as shown.
  • Drain port 65 is closed in Fig. 1, whereby loose material cannot become clogged, when the stopper seats on the first seat. Note that beveled surface 60 is retracted away from seal 61 on part 36. A compression spring 80 in the interior 36c of part 35 exerts axial pressure on part 36, tending to close the stopper against the seats.
  • Fig. 7 shows the dimensions of a particularly advantageous unitary stopper and sealing lip 20 configuration.

Abstract

Dans une vanne, l'invention concerne une combinaison comprenant une chambre de vanne qui comporte un orifice d'entrée d'écoulement et un orifice de sortie d'écoulement, un mécanisme de commande de vanne se situant à l'extérieur de la chambre, un élément obturateur prévu dans la chambre et relié exploitable au mécanisme de commande de vanne en vue d'effectuer un déplacement dans la chambre en direction d'une structure de siège et à partir de celle-ci, afin de réguler l'écoulement provenant de la vanne par l'intermédiaire de l'orifice de sortie. La structure de siège comprend un premier et un second siège; l'élément obturateur est placé de manière à se loger sur le premier siège et à former ainsi une lèvre d'étanchéité flexible portée par l'élément obturateur afin d'entrer en contact d'étanchéité avec le second siège lorsque l'élément obturateur vient s'appliquer sur le premier siège. Des parties mobiles l'une par rapport l'autre qui définissent cette liaison de commande sont conçues pour se déplacer l'une par rapport à l'autre afin de permettre à un écoulement d'air d'entrée d'interrompre le retour d'un liquide, et de libérer une contrepression par l'intermédiaire de passages d'écoulement.
