Description

VALVE HOUSING
THIS INVENTION relates to valves. In particular, it relates to a valve
housing and to a valve for use in a water reticulation system. The invention further
extends to a meter and valve housing arrangement.
According to a first aspect of the invention there is provided a housing
for a valve, the housing including
a valve body defining a central axis and having opposed first and second
ends spaced along the said central axis, and the body having
a centrally located first central opening defined in the first end thereof;
at least one first peripheral opening defined in the first end and radially
outwardly spaced from the first central opening;
a centrally located second central opening defined in the second end thereof;
at least one second peripheral opening defined in the second end and radially
outwardly spaced from the second central opening;
a central passageway extending between the first and second central
openings to define a central fluid flow path;
at least one peripheral passageway, the, or each, peripheral passageway
extending between a first and a respective second peripheral opening to define a
peripheral fluid flow path; and a valve seat defined in one of the central or the, or each, peripheral fluid flow
paths.
Thus, it will be appreciated that a valve seat may be defined in the
central fluid flow path or, where the housing has a single peripheral fluid flow path,
in the said single peripheral flow path or, where the housing has a plurality of
peripheral fluid flow paths, in each of the said peripheral flow paths. In a preferred
embodiment of the invention, the valve seat is defined in the central fluid flow path.
The valve housing may include a first connecting means arranged on
the valve body at the first end thereof for connecting into a fluid flow line. The
first connecting means may comprise a screw thread for co-operating with a
corresponding thread of the flow line.
The valve housing may include a second connecting means arranged
on the valve body at the second end thereof for connecting to a meter housing for
a cylindrical fluid flow metering cartridge. The second connecting means may
comprise a screw thread for co-operating with a corresponding thread of the meter
housing .
The first central opening may be circular. The second central opening
may be circular.
The, or each, first peripheral opening may have at least one curved edge portion concentric with the first central opening . The, or each, second
peripheral opening may have at least one curved edge portion concentric with the
second central opening.
The, or each, first peripheral opening may have a pair of opposed
curved edge portions, each of which is concentric with the first central opening .
The, or each, second peripheral opening may have a pair of opposed curved edge
portions, each of which is concentric with the second central opening .
The, or each, peripheral passageway may have a generally arcuate cross section.
According to a further aspect of the invention there is provided a fluid
flow valve which includes
a valve housing as hereinbefore described; and
a valve closing means operable between an open position in which it is
spaced from the valve seat and a closed position in which it seats against the valve
seat to close the fluid flow path in which the valve seat is defined .
The fluid flow valve may include an electrically actuated displacement
means for displacing the valve closing means between its open and closed
positions. The displacement means may comprise a solenoid .
The valve body may have a cavity for housing a valve closing means defined therein, the cavity intersecting the central passageway and the valve seat
being defined at an intersection of the passageway and the cavity. The cavity may
be circular cylindrical in shape having an axis perpendicular to the central axis of
80 the valve body and a first portion of the central passageway intermediate the first
end of the valve body and the cavity may intersect the cavity at an inner end
thereof, the valve seat being defined at the said intersection of the first portion and
the cavity. A throat of the first portion of the central passageway may have a
circular cross section and may be coaxial with the cavity and a throat-defining
85 portion of a wall of the first portion of the central passageway may protrude into
the cavity to define an annular valve seat.
Then, the fluid flow valve may include
a valve housing as described above;
90 a valve closing means which includes
a piston-like valve closure slidably receivable within a bore of the cavity of
the valve body and axially displaceable therein;
a solenoid receivable within the cavity and operably connected to the valve
closure, the solenoid being operable to displace the valve closure between an open
95 position in which it is spaced from the annular valve seat and a closed position in
which it seats against the annular valve seat to block the central fluid flow stream.
According to a still further aspect of the invention there is provided a
meter and valve housing arrangement for a fluid flow meter and valve combination,
00 the arrangement including a valve housing as hereinbefore described and having second connecting
means arranged on the valve body at the second end thereof; and
a meter housing for a cylindrical fluid flow metering cartridge, the meter
housing including
a meter casing configured to receive the fluid flow metering cartridge;
connecting means arranged at a first end of the meter casing, the connecting
means configured to co-operate with the second connecting means of the valve
housing to permit the valve body and the meter casing to be releasably attached
to one another;
at least one inlet port arranged at the first end of the meter casing, the, or
each, inlet port being configured to correspond with a respective second peripheral
opening of the valve housing; and
an outlet port arranged at the first end of the casing and configured to
correspond with the second central opening of the valve housing.
Instead, the valve housing may include a meter housing for a
cylindrical fluid flow metering cartridge, the meter housing being arranged at the
second end of the valve body, the valve body and the meter housing comprising an
integral one-piece unit.
The invention is now described, by way of example, with reference to
the accompanying diagrammatic drawings in which
Figure 1 shows a partly sectional side view of a first embodiment of a valve,
in accordance with the invention; Figure 2 shows a three dimensional view of the valve;
Figure 3 shows an exploded sectional side view of a meter and valve housing
arrangement for a fluid flow meter and valve combination, in accordance with the
invention, the valve being a second embodiment;
Figure 4 shows an assembled sectional side view of the meter and valve
housing arrangement.
Figure 5 shows a top plan view of a further embodiment of the valve
housing;
Figure 6 shows a side view of the valve housing of Figure 5;
Figure 7 shows a sectional side view of the valve housing through a section
A-A of Figure 6; and
Figure 8 shows a bottom plan view of the valve housing of Figure 5.
In the drawings, reference numeral 1 0 generally indicates a valve in
accordance with the invention. The valve 1 0 is for use in a water reticulation
system, in combination with a water flow meter of a cartridge type.
In Figures 1 and 2, the valve 1 0 has a valve housing 1 2, which has
a generally right circular cylindrical body 1 3, having first and second ends 14 and
1 6 respectively, spaced along a longitudinal axis 1 7 defined by the body 1 3. It will
be appreciated that the housing 1 2 constitutes a valve housing in accordance with the first aspect of the invention .
A pair of first peripheral, or outer, openings 22 are defined in the first end 1 4 of the body 1 3. A first central opening 24 is defined in the first end 14 and
is centrally located in the first end 1 4. A thread 26 is defined on an outer wall 28
of the housing body 1 3 at the first end 1 4 thereof, the thread co-operating with a
corresponding thread of a fluid flow line or manifold, in use, thereby to connect the
valve housing 1 2 into the flow line.
The valve body 1 3 has a pair of second peripheral openings 30 and a
second central opening 32 defined in the second end 1 6 thereof. Further, the valve
body 1 3 defines a pair of peripheral passageways 33, each peripheral passageway
33 extending from a first peripheral opening 22 to a respective second peripheral
opening 30, to define a peripheral inlet fluid flow path 37. In Figure 2, it will be
seen that each of the second peripheral openings 30, has an arcuate outer edge
portion 54 concentric with the second central opening 32. Further, each of the
second peripheral openings 30 has a generally linear inner edge portion 29 opposed
to the outer edge portion 54. The outer and inner edge portions 54 and 29 are
intersected by a pair of opposed short intermediate edge portions 31 . The first
peripheral openings 22, although not shown in plan view, have a similar shape to
that of the second peripheral openings 30 and the peripheral passageways 33 have
a similar cross-sectional shape over their length and have longitudinal axes co-
parallel with the longitudinal axis 1 7 of the valve body 1 3.
The valve body 1 3 defines a central passageway 35 extending
between the first central opening 24 and the second central opening 32, the
passageway defining a return fluid flow path 38 . A first end portion 40 of the central passageway 35, proximate the first end 1 4 of the valve body 1 3, is circular
in cross-section and is co-axial with the body 1 3 A second end portion 41 of the
central passageway 35, proximate the second end 1 6 of the valve body 1 3, is
circular in cross-section and is co-axial with the body 1 3. A generally circular
cylindrical cavity 43 is defined in the valve body 1 3, a longitudinal axis of the
cavity 43 being perpendicular to the longitudinal axis 1 7 of the valve body 1 3. A
first intermediate portion 45 of the central passageway 35 is in communication
with the first end portion 40 of the central passageway 35 and intersects the cavity
43 at an inner end 39 thereof. A second intermediate portion 47 of the central
passageway 35 is in communication with the second end portion 41 of the central
passageway 35 and intersects the cavity 43 at the inner end 39 thereof. Thus, the
central passageway 35 comprises first and second end portions 40 and 41 ,
respectively; first and second intermediate portions 45 and 47, respectively; and
the cavity 43, the central passageway 35 thereby defining the return fluid flow
path 38 which has a U-bend 48 intermediate linear end portions 40 and 41 . A
throat 50 of the first intermediate portion 45 of the central passageway 35 has a
circular cross-section and is coaxial with the cavity 43. A throat defining portion
of a wall 49 of the first intermediate portion 45 protrudes into the cavity 43 to
define an annular nozzle-like valve seat 46.
A piston-like valve seal 52 is operable between an open position in
which it is spaced from the valve seat 46 and a closed position (as shown in the
drawings) in which it seats against the valve seat 46 to close the return flow path
38 In the embodiment of the invention illustrated in Figures 3 and 4, a rubber soft seal 51 is interposed between the valve seal 52 and the valve seat 46, the soft seal
51 forming a seal against the valve seat 46 when actuated by the piston-like valve
seal 52.
The valve seal 52 is solenoid operated and is electrically actuated to
be operable between its open and closed positions. It will be appreciated that such
a solenoid mechanism is well known in the art and is illustrated in Figures 3 and 4,
labelled 57. The solenoid 57 and the valve seal 52 are received within the cavity
43.
It will be appreciated that a second housing (not shown) may be
mounted on the valve housing 1 2 at the second end 1 6 thereof. The second
housing may be integral with the valve housing 1 2, comprising a one-piece unit
therewith, and may define a cavity shaped and dimensioned to accommodate a
fluid flow metering cartridge of a known type.
In Figures 3 and 4, a meter and valve housing arrangement 56 for a
fluid flow meter and valve combination, is shown. The arrangement 56 inlcudes
a meter housing 58 having a casing 59 which defines a meter cavity 60 shaped and
configured to receive a cartridge-type fluid flow meter (not shown) . The meter
casing 59 is releasably attached to the valve housing 1 2 by means of threads 62
defined on the meter casing 59 which co-operate with corresponding threads 64
defined on the second end 1 6 of the valve body 1 3. The meter casing 59 has
defined therein a central outlet port 66 and a pair of peripheral inlet ports 68, the central outlet port 66 corresponding with the second central opening 32 of the valve body 1 3, and the peripheral inlet ports 68 corresponding with the second
peripheral openings 30 of the valve body 1 3, in use. It will be appreciated that
where metering of the fluid flow is not required, the meter housing 58 may be
225 substituted by a cap (not shown) having threads defined thereon, which may be
threadedly connected to the valve housing 1 2 by means of the threads 64 defined
on the valve body 1 3.
The meter and valve housing arrangement 56 further includes a
230 manifold 70 having an inlet 72 and a central outlet 74, the inlet 72 being
connected to a water supply reticulation system (not shown) and the central outlet
74 being connected to a consumer take-off to supply such consumer with metered
water. The manifold 70 has a non-return valve 76 and is threadedly connectable
to the valve housing 1 2 by means of threads 78 defined on the manifold 70 which
235 co-operate with the threads 26 of the valve housing 1 2.
It will be appreciated that a valve 1 0 as described above may be
readily interposed between an existing meter housing 58 and manifold 70, or water
supply line, to provide for electrically actuated control of the supply of water to a 240 consumer.
We turn now to Figures 5 to 8, which illustrate a further embodiment
of the valve housing 1 2, which is similar to the embodiment illustrated in Figures
1 and 2. In Figures 5 to 8, with reference to Figures 1 and 2, like numerals indicate like components unless otherwise specified . As may be seen from Figures
5 and 8, first and second edge portions 80 and 82 of the first and second
peripheral openings 22 and 30 are arcuate and concentric with the first and second
central openings 24 and 32, respectively. Thus, the first and second peripheral
openings 22 and 30 have a generally arcuate shape. The inlet passageways 33
have similar arcuate cross sections throughout and each of the said passageways
33 defines a longitudinal axis which is co-parallel with the longitudinal axis 1 7 of
the valve body 1 3.
