Definitions

  • This invention relates to a water meter and water tap which is usually found at a property's boundary.
  • the invention has particular application to the layout and/or assembly of the water meter and/or the water shut-off device which is used by Water authorities for the controlling and recording of the water supplied to, and used by, a consumer and, for convenience of reference, the invention is hereinafter described in the context of such application. However, it will be understood that the invention does in fact have broader application, to many different fluid applications and various fluid pressures.
  • the shut-of device can be damaged when plumbers and consumers apply too much pressure when turning off screw down shut-off devices. Erosion wear can occur to the valve and valve seat due to impurities in the water supply. In those instances where the Water authorities are responsible for repairing and maintaining the whole assembly, large amounts of money are expended to repair damaged shut-off devices and to replace worn valves. In order to carry out this maintenance, special equipment is needed to interrupt the water supply flow upstream of the device (on the mains side of the shut-off device) . This is usually done by cutting off the water in the pipe upstream of the shut-off device. Many of the Water authorities who e poly the "user pays" principal, replace the water meters every ten to twelve years as the older meters tend to become inaccurate and read "slow".
  • Manifold Meters have overcome the need to break into the line when replacing the metering/recording unit.
  • the actual meter devices are easy to remove, they are not tamper proof and are easily interfered with and can be replaced by a simple cover plate. This not only allows water to be consumed without being metered, but the interference is hard to detect after the meter unit has been restored to its original position.
  • one embodiment of the current invention seeks to provide a water meter/measuring and shut-off device assemblies which are easily and completely serviceable and totally replaceable without having to disturb the connection joints of the water pipe network. This is achieved by providing a connection mounting assembly which is permanently installed into the water pipe network and which has the facility of allowing the water metering device assembly and entire shut-off device assembly (including the valve, valve seat, spindle and handle) to be mounted directly onto it.
  • the metering device assembly and the shut-off device assembly are combined into the one unit and then mounted onto the connection mounting assembly.
  • the connection mounting assembly has at least one secondary valve installed at its supply outlet upstream of the primary shut-off device assembly.
  • the secondary valve is preferably removable from the conenction mounting assembly.
  • the secondary valve is biased in the direction of the flow of water.
  • the housing of the shut-off device assembly is designed in such a way that when the shut-off device assembly is removed from the connection mounting assembly, the secondary valve is allowed to close thus terminating the flow of water.
  • the housing of the shut-off device assembly is designed in such a way that an interconnection, which may be a movable link, is installed which co-operates with the secondary valve allowing the secondary valve to be activated without first removing the body of the shut-off device assembly from the connection mounting assembly.
  • the interconnection between the shut-off device assembly and the secondary valve is designed in such a way that it may be removed, thus disabling the unit from operating, and providing a quick, inexpensive and effective termination of the consumers water supply.
  • connection mounting assembly has at least one non-return check valve device installed at its supply inlet downstream of the metering device assembly.
  • the non-return check valve device is removable from the connection mounting assembly.
  • the outlet orifice from the metering device assembly contains at least one non-return check valve device.
  • the metering device assembly can be easily removed from the connection mounting assembly so as to allow for a flow rate test to be carried out to check and verify the meters accuracy.
  • connection mounting assembly is made of brass.
  • connection mounting assembly is expected to have a working life in excess of sixty years, and as the upper outer casings are made from injection moulded plastic, this provides a very quick and inexpensive method for the Water authorities to replace the water meter, while at the same time replacing the shut-off device as well.
  • shut-off device assembly for control of fluid flow in pipes, comprising a valve, a valve seat, a fluid passageway, a tap body (or shut-off device body) , an activating mechanism, all of which is mounted upon, a connecting mounting assembly that has at least one inlet end and one outlet end and contains a secondary valve which is linked to the shut-off device assembly.
  • the connection mounting assembly has more than one inlet.
  • connection mounting assembly has more than one outlet.
  • the secondary valve in the connection mounting assembly can be held open by the shut-off device assembly.
  • the secondary valve in the connection mounting assembly can be held open by the position of the shut-off device assembly's valve.
  • the connection mounting assembly can remain installed in a pipe network while the action of removing part of the shut-off device assembly allows the secondary valve to interrupt the flow of fluid through the said connection mounting assembly.
  • the connection mounting assembly can remain installed into a pipe network while the action of removing the entire shut-off device assembly allows the secondary valve to interrupt the flow of fluid through the said connection mounting assembly.
  • the secondary valve is operated by a device attached to the body of the shut-off device assembly.
  • the removal of the device controlling the secondary valve allows this valve to close thus interrupting the flow of fluid.
  • a removable cover conceals the device controlling the secondary valve thus maintaining the outer appearance of the shut-off device assembly.
  • the secondary valve is biased in the direction of the normal flow of the fluid.
  • the secondary valve operates independently of the operation of the shut-off device.

  • the shut-off device assembly contains a valve assembly comprising, a valve body member which is held open, a valve seat member and an annular sealing member which is arranged to be located around the periphery of the valve seat member, when in use the annular. sealing member being arranged to form a seal with the valve body member and the shut-off device's valve seat, when the valve body member is forced against the annular sealing member.
  • valve seat member projects proud of the annular sealing member and the annular sealing member is contained within a retainer ring which also projects proud of the annular sealing member thus helping ensure that the annular sealing member is not in direct contact with the flow of fluid- This increses the longevity of the valve seal.
  • valve disc of the valve body member has an annular sealing surface on its lower face which protrudes from the lower surface from the valve body member.
  • valve seat member is made from metal to ensure maximum protection against erosion wear which can be caused by solid impurities contained within the fluid flowing through the shut-off device assembly.

Abstract

Raccord (31) destiné à être installé dans une conduite et comprenant un passage en amont pourvu d'orifices d'entrée et de sortie (32, 33) ainsi qu'un passage en aval également pourvu d'orifices d'entrée et de sortie (34, 35). L'orifice de sortie en amont et l'orifice d'entrée en aval présentent des axes centraux qui ne coïncident pas et sont agencés de façon à être raccordés à un dispositif de contrôle de liquide (75) qui contient un passage reliant réciproquement les passages en amont et en aval, ce dispositif comprenant un dispositif de surveillance (67, 87) servant à mesurer une certaine quantité de liquide, ainsi qu'un régulateur d'écoulement (10, 88) sous forme d'une soupape d'arrêt. Le raccord (31) ou le dispositif de contrôle de fluide peuvent comprendre des soupapes de non-retour (43, 70, 81, 106, 109) pour écoulement à contre-courant et une soupape droite de non-retour (24, 59).
