Definitions

  • a SHUT-OFF VALVE ASSEMBLY This invention relates to a shut-off valve assembly for regulating the flow of fluid through or from a tap or pipe or other type of fluid line.
  • a problem with most conventional taps is that if left on by accident, then fluid will continue to flow from the tap until the tap has been turned off or until the source of the fluid has depleted of fluid.
  • An associated problem is that a receptacle (eg. basin, tub or sink) being filled with fluid may overflow and the fluid overflow may cause damage to surrounding benches, fixtures, flooring and furnishings.
  • Methods for preventing fluid overflows are known.
  • One way in which an overflow can be prevented is to use a sink that has an overflow outlet. When the fluid level reaches the overflow outlet, the fluid level ceases to rise as the fluid simply drains through the overflow outlet.
  • Another method for preventing overflows entails using a sink plug having an overflow tube extending through the plug, wherein the tube extends to a point below a top rim of the sink. Overfilling the sink is prevented as fluid simply drains through the tube and plug into the sink outlet.
  • a shut-off valve assembly for regulating the flow of fluid through or from a fluid line, said assembly comprising: a body attachable to or within a fluid line and having at least one chamber therein with at least one inlet and one outlet for fluid from the fluid line; a valve seat that provides the outlet; a baffle arrangement located within the chamber; a valve member having a sealing member movable between a shielded position, whereby the sealing member is substantially shielded by the baffle arrangement from a fluid stream moving from said inlet to said outlet, and an unshielded position, whereby the sealing member is movable by the fluid stream against the valve seat to seal the outlet; and a drive for moving the sealing member between the shielded and unshielded positions.
  • the body can be attached to or within the fluid line (eg. tap or pipe) by any suitable means known to persons skilled in the art. If the body is to be attached to an end of a threaded tap then the body can, for example, have a like threaded end. Alternatively, the assembly can have a hydraulic coupling for quick and easy attachment of the body to a variety of unthreaded taps. Such couplings are well known in the art.
  • the body can have opposing threaded ends for attachment between adjacent pipe sections.
  • the body can, for instance, have an outer threaded surface for attachment to a like-threaded inner surface of a pipe.
  • the body can friction fit within a part of the fluid line, such as within an interior compartment of a tap.
  • the body can be of any suitable shape and size.
  • the body can comprise two or more connecting pieces.
  • the body has a cylindrical sidewall and an attachable end cap, and the end cap has the inlet.
  • the end cap can provide access to the valve member etc. for maintenance or replacement. If the body is to be attached to an end of a threaded tap, then the end cap can have a threaded spout and the inlet can be located at the end of the spout.
  • the baffle arrangement can comprise any suitable number and arrangement of baffle walls.
  • the baffle arrangement comprises a baffle housing for housing the sealing member when in the shielded position.
  • the baffle housing can have a top wall and at least one sidewall, and the sidewall can extend from the top wall towards the valve seat.
  • the baffle housing together with the body can define at least one passage through which fluid can flow to the outlet.
  • the chamber can have flow restrictors for slowing the flow of fluid from the inlet to the outlet. Any suitable type of flow restrictor can be used.
  • the baffle arrangement comprises additional walls for slowing the flow of fluid. More preferably, perforated walls extend between the baffle housing and the body to slow fluid flow.
  • the valve member can be of any suitable shape and size.
  • the sealing member can comprise a support disk having a rubber surface facing the valve seat. The rubber surface can be provided by, for instance, a disk of neoprene or like material, or a teflon O-ring. An opposing surface of the support disk can be dome-shaped.
  • the valve member can have a stem extending from the sealing member. Preferably, the stem is rod-shaped.
  • the valve seat can be of any suitable shape and size.
  • the valve seat can have a rubber surface facing the sealing member.
  • the rubber surface can be provided by, for instance, a layer of neoprene or like material, or an O-ring.
  • the outlet can be provided by a central aperture of the valve seat. Alternatively, if the chamber has more than one outlet, then these can be provided by a plurality of apertures spaced about the valve seat.
  • the apertures can be annually spaced about the valve seat.
  • the valve seat can have an annual groove for receiving an O-ring of the sealing member, and one or more outlets can be located within the groove.
  • An outer periphery of the valve seat can be threaded and can be attached to a like threaded region of the body, or between like threaded regions of the body.
  • the assembly can have a pressure relief valve for venting fluid from the chamber after the sealing member has sealed the outlet. Without a pressure relief valve it may be difficult to detach the assembly from the fluid line.
  • Any suitable type of pressure relief valve arrangement can be used.
  • the pressure relief valve can be in the form of a tap or a spring- loaded push-button valve that extends from the body. Spring-loaded push-button valves and the like are known in the art.

Abstract

L'invention concerne un ensemble vanne d'arrêt (50) permettant la régulation de l'écoulement du fluide dans ou depuis une conduite de fluide. L'ensemble (50) comprend: un corps (52) pouvant être fixé à ou dans une conduite de fluide et renfermant une chambre (61) pourvue d'entrées (64) et d'une sortie (65) pour le fluide de cette conduite de fluide; un siège de valve (53) qui constitue la sortie (65); un ensemble déflecteur comportant un boîtier déflecteur (55); un élément valve (54) ayant un élément d'étanchéité (68) mobile entre une position protégée, dans laquelle l'élément d'étanchéité est sensiblement protégé, par le boîtier déflecteur (55), d'un courant fluidique se déplaçant des entrées (64) jusqu'à la sortie (65), et une position non protégé, dans laquelle l'élément d'étanchéité (68) est plaqué par le flux fluidique contre le siège de valve (53) destiné à l'étanchéité de la sortie (65) et un moyen de commande permettant de déplacer l'élément d'étanchéité (68) entre les positions protégé et non protégé. Le moyen de commande peut être une liaison mécanique d'un flotteur ou une commande directe d'un solénoïde. Le solénoïde peut être activé par des capteurs déterminant le niveau de fluide dans un contenant rempli, le détecteur étant un capteur laser, un capteur d'infrarouge, un micro-interrupteur déclenché par un flotteur ou un poids sur un tapis sensible à la pression.
