(54) IMPROVEMENTS IN OR RELATING TO METHODS
AND APPARATUS FOR CONTROLLING THE
FLOW OF LIQUIDS
(71) I, DONALD GEORGE EKE of 11 Balmoral Road, Gaywood, Kings Lynn,
Norfolk a British Citizen do hereby declare the invention, for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following state ment :- This invention relates to a method and to apparatus for controlling the flow of liquid.
There is, from time to time, a requirement to fill a receptacle automatically and without supervision to a given level from a flow of liquid in a conduit, but to ensure that once the receptacle is filled to that level the continuation of the liquid flow is maintained in the conduit alone and the liquid does not escape to the outside from the region containing the receptacle and that portion of the conduit. For example, there is such a requirement in the filling of domestic water butts from the flow of rainwater in downpipes which commonly are connected directly to the waste water or sewage system.
According to the present invention there is provided a method for controlling liquid flow under gravity comprising directing the liquid into a chamber through an inlet aperture in the chamber located above two continuously open outlet apertures in the chamber whereby liquid entering the chamber falls freely towards one of the outlet apertures and, preferentially directing liquid emerging from said inlet aperture through the other one of said outlet apertures.
According to the invention also there is provided apparatus for controlling liquid flow under gravity comprising a liquid downpipe having vertically spaced open ends, a housing, and a subsidiary outlet pipe, the housing defining a collecting chamber having an inlet aperture connected to the upper of said downpipe ends, a first outlet aperture located vertically below the inlet aperture and connected to the lower of said downpipe ends, and a second outlet aperture connected to said subsidiary outlet pipe, there being liquid flow pathways between said inlet and each of said outlet aperture, and the housing for this including baffle means locatable in said chamber preferentially to direct liquid emerging from said inlet aperture into said second outlet aperture, the arrangement being such that when there is resistance to liquid flow through said second aperture liquid is able to flow from said inlet aperture to said first outlet aperture.
Preferably the baffle means are fixed with respect to the chamber and preferably also the inlet and first outlet apertures are coaxial. In a particularly preferred embodiment of the invention a liquid trap is provided around said first outlet aperture which, when full of liquid, prevents gaseous fluid passing from the first aperture into the chamber.
In a further preferred embodiment of the invention the apparatus said housing defining said chamber has a opposed wall portions, in which are formed coaxially arranged apertures forming said inlet and first outlet apertures and for receiving respectively the ends of the upper and lower pipe sections, and a wall portion between said opposed wall portions in which is located a third aperture forming said second outlet aperture, and wherein said baffle means comprises a deflector means extending transversely with respect to the axis of said coaxial apertures and blocking the direct liquid flow pathway between said coaxial apertures and arranged to deflect liquid entering said chamber through said inlet aperture towards said second outlet aperture.In a still further preferred embodiment of the invention said housing and said baffle means thereof define a subsidiary chamber within the collecting chamber into which said second outlet opens, the inlet aperture being arranged so that liquid emerging therefrom enters said subsidiary chamber and can pass into said second outlet aperture. Preferably, said housing defines a liquid flow pathway enabling liquid to flow from said subsidiary chamber to said first outlet aperture.
In a still further preferred embodiment of the invention the housing includes a bottom floor portion and a side wall portion in which the said second outlet aperture is located at a point spaced from said floor portion, said first outlet aperture also being spaced above said floor portion whereby the portion of the chamber below the first and second outlet apertures comprises a trap for liquids, and wherein said baffle means, alone or in association with parts of said housing, extends downwardly around said first outlet aperture and defines a space immediately above this aperture to which there is access only by way of the space between the floor portion and the baffle means.
In particular application of this invention in the collection of rainwater the invention provides the combination of apparatus as defined in any one of the preceding paragraphs with the spaced upper and lower sections of a rainwater downpipe, the lower end of the upper section extending into the inlet aperture and the upper end of the lower section extending into the first outlet aperture of the chamber.
The invention will now be described with reference to preferred embodiments of the invention, given by way of example only, which are illustrated in the accompanying drawings in which,
Figure 1 is a schematic cross-section of a first embodiment of apparatus according to the invention in combination with upper and lower sections of a rainwater downpipe;
Figure 2 is a view similar to that of Figure 1 of a second embodiment of the invention;
Figure 3 is a view similar to that of Figure 1 of a still further embodiment of the invention; and
Figure 4 is a view similar to that of Figure 1 of a still further embodiment of the invention.
In the embodiment illustrated in Figure 1 the housing 1 has a bottom floor portion 2, a side wall portion 3 and a cover portion 4, which together define a collecting chamber 5.
An aperture 6 is formed in the cover portion 4 of the housing and the lower end 7 of an upper pipe section of a rainwater downpipe is located in the aperture 6.
A tubular projection 8 extends upwardly from the floor portion 2 of the housing 1 and i$ arranged coaxially with the aperture 6.
The upper end of the tubular projection 8 forms a first outlet aperture from the collecting chamber 5. The top of the projection 8 is folded back on itself to define a groove for receiving a top edge of the upper end 9 of a lower piper section of a rainwater down pipe. The two ends 7 and 9 of the sections of downpipe are coaxial and spaced from each other.
The bottom floor portion 2 and the adjacent side wall portion 3 of the housing together with the tubular projection form a subsidiary chamber 10 within the housing 1.
A second outlet aperture 11 is provided adjacent the floor portion to the housing and has integral therewith a conduit 12 which opens into a rainwater collecting barrel 13.
The tubular projection 8 forms a part of baffle means which also comprise a triangular member 14 mounted on supports 16 of a member 15 located in the open mouth of the projection 8. The walls of the triangular member 14 are dimensions such as to completely cover the aperture in the projection 8.
Projections 18 and 19 from the housing 1 are provided for fixing the housing to a wall or other convenient structure adjacent to the rainwater downpipe. In use of the embodiment of the invention illustrated in
Figure 1, water from the guttering system is channelled down the pipe section 7 and emerges into the collecting chamber 5. The water contacts the members of the triangu- lar member 14 of the baffle means and is directed into the subsidiary chamber 10.
From the subsidiary chamber 10 the water is free to flow into the barrel 13 and to fill this as far as the level marked by the line 17 in the drawing. At this point the level of the water has reached the level of the top of the projection 8 and commences to flow through gaps between the supports 16 of the baffle means and through the first outlet aperture and into the upper end 9 of the lower section of the rainwater downpipe.
The baffle means comprising the tubular projection 8 and the triangular member or deflector plate 14 are fixed in relation to the housing. The device itself however, is able to maintain a maximum level in the water barrel in an unsupervised fashion and to ensure that any water surplus to requirements is retained within the drainage system leading to the main drainage conduits.
Although in the embodiment illustrated in Figure 1 the upper end of the lower pipe section is contained within a tubular projection 8 of the housing, in a modification of this embodiment the tubular projection 8 is dispensed with and the upper end 9 of the lower pipe section is itself used to define the baffle means and the subsidiary chamber 10.
It is of course necessary to seal the end 9 of the downpipe in the floor portion 2 of the housing.
In the embodiment illustrated in Figure 2 of the drawings there is again provided a housing 101 whic comprises a floor portion 102, a side wall portion 103 and a cover portion 104 which together define a collecting chamber 105. An aperture 106 is formed in the cover portion 104 of the housing and the lower end 107 of an upper section of a rainwater downpipe extends into the aperture 106. A tubular projection 108 is formed in the floor portion of the housing and extends both above and below the floor portion of the housing, the bottom portion of the tubular projection 108 extending into the upper end 109 of a lower section of a rainwater downpipe. This lower portion of the tubular projection 108 serves to locate the housing with respect to the downpipe and the housing itself rests upon the downpipe.
In this embodiment of the invention the baffle means comprise a vertical member 110 and a horizontal member 111 which both extend between opposite side wall portions of the housing and the horizontal member 111 also extends between the vertical member 110 and a side wall portion of the housing. The side wall portion of the housing, the member 111 and the upper portion of the member 110 together define a subsidiary chamber 112 which is located directly below the inlet aperture 106.
The lower end of the vertical member 110 of the baffle means extends below the upper point of the tubular projection 108 and the tubular projection lies immediately below the subsidiary chamber 112. The upper open mouth of the tubular projection 108 forms the first outlet aperture 113 from the collecting chamber and a second outlet aperture 114 is formed in a side wall portion of the housing which defines the subsidiary chamber 112. There is space between the upper edge of the vertical member 110 and the cover portion 104 of the housing and between the lower edge of the vertical member 110 and the floor portion 102 of the housing.
A vertically extending fluid pathway ex- tends between the vertical member and the side portion 103 of the housing remote from the subsidiary chamber 112.
The vertical member 110 together with the tubular projection 108 and the surrounding side wall portions of the housing and the floor portion 102 of the housing together define a liquid trap which becomes full of liquid during use of the invention. Since the tubular projection 108 terminates within the space defined by the member 110 and the horizontal baffle member 111 there is no path for gaseous fluid from the pipe end 109 when the trap is full of liquid.
In use of the embodiment illustrated in
Figure 2 rainwater is directed from the end 107 of the upper section of the rainwater downpipe through the aperture 106 into the subsidiary chamber 112. The water is then free to flow out of the second outlet aperture 114 into a suitable receptacle until the level in the receptacle reaches the uppermost level of the subsidiary chamber 112 as defined by the upper edge of the vertical member 110 of the baffle means.
Water then flows down the fluid pathway into the liquid trap at the bottom of the collecting chamber and when this is full flows through the first outlet aperture 113 into the end 109 of the lower downpipe section.
In a modification of this embodiment the tubular projection is dispensed with and, as in the first embodiment the upper end 109 of the lower section of the downpipe is introduced into the housing and utilised in association with the other portions of the housing and the baffle means to form the liquid trap.
In the embodiment illustrated in Figure 3 a housing 201 has a floor portion 202, side wall portion 203 and a cover portion 204, which together define a collecting chamber 205. An aperture 206 is formed in the cover portion 204 and receives the lower end 207 of the upper section of the rainwater downpipe. A tubular projection 208 is formed integrally with the floor portion of the housing and extends above and below the floor portion of the housing. The lower portion of the projection 208 is located within the upper end 209 of a lower section of rainwater downpipe and the upper end of the tubular projection defines a first outlet aperture 210 from the collecting chamber 205.
The floor portion 202 and the tubular projection 208 together with the surrounding side wall portion 203 define together a subsidiary chamber 211 and a second outlet aperture 212 is in communication with the subsidiary chamber 211. The upper edge of the projection 208 lies above the lower limit of the aperture 212.
Baffle means 213 comprise angled members 214 and 215, which extend between opposed wall portions of the housing 201 and block the direct fluid pathway between the coaxial inlet aperture 206 and outlet aperture 210. Downwardly extending members 216 and 217 respectively connected and sealed to the angled members 214 and 215 extend below the lower limit of the second outlet aperture 212. The space within the elements 214 - 217 of the baffle means is therefore a closed space which is only accessible by way of the gap between the bottom edges of the elements 216 and 217 and the floor portion 202 of the housing.In use of the embodiment illustrated in Figure 3 water is collected and fed down the upper section of the rainwater downpipe and emerges through the aperture 206 and is deflected by the angled elements 214 and 215 of the baffle means into the subsidiary chamber 211 of the collecting chamber 205.
From there the water flows through the aperture 212 into a suitable collecting receptacle which may be a water barrel. When the level in the receptacle has reached the level of the aperture 210 in the tubular projection 208, the water commences to flow under the lower extremities of the vertical member 216 and 217 of the baffle means and down the interior of the tubular projection 208 into the upper end 209 of the lower pipe section of the rainwater downpipe. When rainwater ceases to flow into the collecting chamber and is removed from the receptacle the level of water within the chamber reduces to a level defined by the lower limit of the second outlet aperture 212 and ensures that a liquid trap is left in the bottom of the chamber which prevents smells rising from the drainage system.
In common with the other embodiments described above, various alterations may be made in the specific arrangement of projection 208 and the various downpipe sections in modifications of this embodiment also.
A further embodiment of the invention is illustrated in Figure 4 of the drawings. A housing 301 is formed as a tubular element which is arranged vertically and has its upper end forming an inlet aperture 302 in which is received the lower end 303 of an upper pipe section of a rainwater downpipe and its lower end defining a first outlet aperture 304 which is surrounded by the upper end 305 of a lower section of a rainwater downpipe.
A second outlet aperture 306 is defined in a sidewall of the housing 301 and has a short tubular element 307 secured therein. An outlet pipe 308 leading to a receptacle (not shown) extends through the tubular element 307 and has its mouth located in the interior of the tubular housing 301 which interior defines a collecting chamber. Baffle means in this embodiment are defined by a deflector plate which extends between opposed wall portions of the housing and is secured to the walls of the housing in a position to block the pathway between the coaxial inlet aperture 302 and first outlet aperture 304.
The deflector plate 309 is inclined to the vertical and has its lower edge 310 located adjacent the mouth of the outlet pipe 308 and its upper edge 311 adjacent the wall portion of the tubular housing 301 remote from the second outlet aperture 306.
In use of the embodiment shown in Figure 4 water emerges into the collecting chamber defined by the housing 301 through the aperture 302 and is deflected by the plate 309 into the mouth of the outlet pipe 308 lying in the second outlet aperture 307 from the collecting chamber. If there is not resistance to water flow through the pipe 308 then water is preferentially directed down the outlet pipe 308 from the second outlet aperture 306. If there is resistance to water flow down the pipe 308 because the receptacle is full, there is back pressure which causes the water to flow around the lower edge 310 of the deflector plate and through the first outlet aperture 304 into the upper end 305 of the lower section of rainwater downpipe.
The invention has been described with reference to a number of embodiments in all of which the baffle means are fixed in position and the apparatus of the invention provides an unsupervised and automatic replenishment of a receptacle to a given level and ensures that any liquid surplus to requirements is directed in a safe and convenient manner down a disposal pipe.
The invention has been particularly described with reference to the collection of rainwater. The invention may however be used in connection with the conversation of other liquids in other situations. In addition, in the description of the particular embodiments of the invention it is suggested that the rainwater should be diverted into a water barrel. In certain situations it could also be possible to direct the water into normal domestic water storage tanks for use in supplying lavatory systems or the domestic cold water or hot water supply systems.
If necessary, filters may be provided over the various apertures as required. In addition, rubber grommets or other sealing means may be provide as necessary at the joints between various elements of the apparatus of the invention as described.
