Abstract
Description
- The present invention relates to apparatus and method of installing the apparatus, used particularly but not exclusively for safely expelling water from the pressure relief valves of household combination boilers.
- Demand for combination household boilers has grown due to their efficiency and convenience. Such boilers are typically maintained at pressure as this improves their efficiency. There is a danger that critical failures such as a pump or thermostat failure will cause the boiler to overheat and thus the pressure to rise to unsafe levels. Accordingly, for safety purposes, such boilers are provided with a pressure relief valve which allows pressure to be relieved from the boiler when pressure safe levels are exceeded.
- Typically, a pressure relief pipe is connected to the pressure relief valve in order that water, which is typically at very high temperature and pressure, can safely be expelled from an internally housed boiler to the outside environment.
- Conventionally, as shown in Fig. 1, water is expelled from a
boiler 10 via aaperture 12 through anexternal wall 14 of a building, theaperture 12 being of substantially identical diameter to the outside diameter of anoutlet pipe 16. Generally, theaperture 12 andpipe 16 are approximately 15mm in diameter. Theoutlet pipe 16 is passed through theaperture 12 and the internal end of thepipe 16 is connected to the pressure relief valve of theboiler 10. A standard double-ended elbow fitting 18 (normally formed of two Yorkshire bends and a small length of pipe which are fitted/welded or soldered together) are then attached to the external end of theoutlet pipe 16, thus directing any expelled water back against thewall 14. The water cools as it runs safely down thewall 14. - Unfortunately, it is not possible to fit the double-ended elbow fitting 18 to the
outlet pipe 16 prior to passing it through theaperture 12. The double-endedelbow fitting 18 must be fitted to the outside end of theoutlet pipe 16 after it has been passed through theaperture 12 in thewall 14. Installation of theelbow fitting 18 can be inconvenient and dangerous since theoutlet pipes 16 often exits thewall 14 well above ground level or in inaccessible positions. - Consequently, in practice, the installer often does not fit the required external elbow fitting 18, resulting in the possibility of high temperature/pressure water being expelled from the building without being directed back against the
wall 14. Obviously there is danger that the expelled water can scald passers-by or animals as they pass by or under the external end of theoutlet pipe 16. - According to a first aspect of the present invention there is provided apparatus for expelling fluid to the external environment from a boiler situated internally of a building, the apparatus comprising a conduit connectable at its first end to a pressure relief valve on said boiler and having its second end open, in use, to the external environment wherein the conduit has an end portion connected to its second open end, said end portion being adapted to intercept fluid expelled from the second open end of the conduit.
- Preferably, the conduit and end portion are of circular cross-section and the end portion has a diameter greater than that of the conduit.
- Preferably, the end portion is cup shaped and has its concave inner surface facing the open end of the conduit.
- Preferably, the inner surface of the cup-shaped end portion is adapted to deflect fluid expelled from the conduit in a desired direction.
- Preferably, said end portion is attached to said conduit via a plurality of spokes extending radially from the conduit.
- Preferably, a grille covers the opening of said cup shaped end portion.
- Preferably, the grille is annular in shape and is connected at its outer edge to the cup shaped end portion and at its inner edge to the second open end of the conduit.
- Preferably, perforations are provided in said grille and adapted to direct expelled fluid in a desired direction. The perforations may comprise one or two apertures or may comprise numerous apertures.
- Preferably, the conduit is adapted to extend from a connection to said pressure relief valve on the internally situated boiler to the external environment via an aperture in an external wall of said building.
- Preferably, a sleeve surrounds at least part of the conduit.
- Preferably, the diameter of the end portion is less than or equal to the diameter of the sleeve.
- Preferably, lids are provided on either end of the sleeve having apertures therein to permit the passage of the conduit therethrough.
- Filling material may be introduced between the outer surface of the conduit and the inner surface of the sleeve to substantially fill the gap between the two.
- Preferably, in use the sleeve is held in position within the aperture by a sealant.
- Preferably, a weather seal is provided which acts as a barrier between the internal and external environments.
- Preferably, the end portion is pre-fitted to the conduit during manufacture.
- Preferably, markings are provided on the apparatus to assist in ascertaining its correct rotational orientation during installation such that fluid is deflected and/or directed in a desired direction.
- Preferably, markings are provided on the apparatus to assist in ascertaining the length of the apparatus such that the apparatus can be cut to the correct length for installation.
- Preferably, the boiler is a household combination boiler.
- Preferably, the end portion is formed of copper.
- Alternatively, the portion is formed of a plastics material.
- Preferably lids are provided on either end of the sleeve, with apertures to permit the passage of the conduit therethrough.
- According to a second aspect of the present invention there is provided a method of installing the apparatus of the first aspect comprising the steps of:
- i) forming an aperture through an external wall of sufficient dimensions to allow passage of the apparatus therethrough;
- ii) inserting the apparatus with the pre-attached end portion into the aperture;
- iii) positioning the apparatus such that the end portion lies beyond the external surface of the wall; and
- iv) connecting the first end of the conduit to the boiler.
-
- Preferably a sealant is inserted between the aperture and the sleeve.
- Preferably, filling material is introduced between the outer surface of the conduit and the inner surface of the sleeve to substantially fill the gap between the two.
- Preferably, the conduit and the sleeve are pre-cut to the desired length. This may be done using markings on the apparatus.
- Preferably, the apparatus is rotated into its correct orientation using pre-formed markings on the apparatus.
- Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings in which:
- Fig. 1 shows a schematic cross-sectional view of a conventional safety apparatus with double-ended elbow fitting;
- Fig. 2 shows a perspective view of the safety apparatus of the present invention;

- Figs. 5 a) and 5 b) show the end portion of the safety apparatus of Fig. 2;
- Fig. 6 shows an alternative embodiment of the present invention in which the conduit is offset relative to the longitudinal central axis of the sleeve; and
- Fig. 7 is a schematic perspective view of the apparatus of Fig. 2.
-
- Referring to Figs. 2 to 7, there is illustrated safety apparatus 1 comprising a
conduit 16 of circular cross section connected at its first end to a pressure relief valve of ahousehold boiler 10 and a sleeve 22 (typically of diameter 22mm) surrounding the conduit 16 (typically of diameter 15mm) within anaperture 12 in anexternal wall 14. - The inner diameter of the
sleeve 22 is greater than the outer diameter of theconduit 16 thus defining a space between theconduit 16 and thesleeve 22. The outer diameter of the sleeve is substantially equal to the diameter of theaperture 12. -
Lids conduit 16 within thesleeve 22. - An
end portion 20 is provided on the second end of theconduit 16 which, in use, lies externally of the building. Theend portion 20 is generally 'cup' shaped and is connected to theconduit 16 via spokes which extend radially from the second end of theconduit 16. The diameter of theend portion 20 is greater than that of the conduit but is sufficiently small to be transmitted through theaperture 12 in thewall 14. Theend portion 20 is of suitable dimensions to avoid it protruding significantly from thewall 14. Theend portion 20 is of less than or equal diameter to the diameter of thesleeve 22. - The internal concave surface of the cup-shaped
end portion 20 faces the second open end of theconduit 16. The internal surface of the cup-shapedend portion 20 is adapted to deflect water expelled from theconduit 16 in a desired direction. Deflection may be achieved by integral angled portions within the concave internal surface and/ordirectional flaps 28. Thedirectional flaps 28 are selectively orientated (preferably to direct the fluid downward). The desired orientation of the directional flaps (or the integral angled surfaces) corresponds to markings provided on the conduit 16 (or on the sleeve 22). - Markings are also provided to indicate where to cut the apparatus to the correct length such that the
end portion 20 will protrude the desired length from the wall, the distance betweenlid 42 andend portion 20 being of a predetermined length. The length of the apparatus required will depend on the thickness of the wall. - An annular shaped
grille 21 covers the opening of the cup-shapedend portion 20 and is connected at its outer edge to the cup-shapedend portion 20 and at its inner edge to the free end of theconduit 16. Thegrille 21 therefore forms a tight fit around theconduit 16. Thegrille 21 is provided with perforations which are adapted to direct expelled water in a desired direction. Perforations can include numerous apertures or a generally solid plate having one or two apertures in the desired direction. - In use, the apparatus 1 is installed by first forming the
aperture 12 through the external wall 14 (i.e. by drilling). Theaperture 12 must have a large enough diameter to allow theend portion 20 to pass through to the outside. The installer then passes the apparatus 1 (having theend portion 20 attached) through theaperture 12 until theend portion 20 is suitably positioned beyond the external surface of theexternal wall 14. In its preferred position, theend portion 20 will have sufficient clearance from theexternal wall 14 to allow water to be expelled effectively but will not protrude excessively from thewall 14.Non-setting sealant 24 is then inserted into the space between thesleeve 22 and the aperture. The internal end of theconduit 16 of the apparatus 1 can then be connected to pressure relief valve of thehousehold boiler 10. - When the
household boiler 10 pressure exceeds safe levels, the pressure relief valve of theboiler 10 allows pressurised water to escape through theconduit 16 towards theend portion 20. When the water is expelled from the second open end of theconduit 16 it is directed against the inside surface of theend portion 20 and is deflected back safely against thewall 14. Thenon-setting sealant 24 ensure that the apparatus 1 is held securely in place, in thewall 14, and also provide a protective barrier from external elements and prevent the fluid from returning to the interior of the building. - A further weather seal (not shown) is provided which acts as a barrier between the internal and external environments.
- Markings (not shown) are provided on the apparatus 1 to assist in ascertaining the correct rotational orientation of the apparatus 1. For example a groove may be provided on the
conduit 16. - Length markings may also be provided to assist in cutting the apparatus to a desired length.
- Modifications and improvements may be made to the foregoing without departing from the scope of the invention.
- For example, the
conduit 16 may be sloped at an angle relative to the horizontal such that fluid can flow more easily from theconduit 16 in order to avoid build-up of fluid. - As seen in Fig. 6, the
conduit 16 may be eccentrically situated with respect to the longitudinal axis of thesleeve 22 to assist in the flow of fluid onto thewall 14. - The
conduit 16 may have any shaped cross section, such as square, or triangular. - The
sleeve 22 is preferred but may be omitted, with the space between theconduit 16 and thewall 14 being filled with an appropriate filler. - The
end portion 20 may be made of a material which has a high resistance to heat and corrosion, therefore prolonging the lifetime of the apparatus. - The
end portion 20 may have a number of spokes located within the cup which project radially inward and connect to theconduit 16, rather than theconduit 16 having spokes which project radially outwards. These may be moulded onto theend portion 20 during manufacture. - The
end portion 20 may have a profile which prevents build-up of snow or dirt on its top surface, for example an inverted tear drop shape. - The
end portion 20 may be attached to thesleeve 22 directly by way of a plastic strip, the strip acting as a bridge between theend portion 20 andsleeve 22. This removes the need to attach theend portion 20 to theconduit 16. - The
end portion 20 may be any shape that directs the fluid back towards thewall 14 effectively. - A
space filing material 26 may be used to fill the space between the outer surface of theconduit 16 and the inside surface of thesleeve 22. - The
space filling material 26 may be made of material which has a high resistance to heat, therefore prolonging the lifetime of the apparatus. - The
space filling material 26 may be made of epoxy resin, fibre-glass, foam, rubber, silicon sealant, or any other appropriate material. - The
space filling material 26 is optional. Theconduit 16 could be secured and insulated by other means, for example, a lid situated at either or both ends of the sleeve. The lid having a diameter similar to that of thesleeve 22 with a aperture provided to accommodate theconduit 16. - The
wall 14 need not be an external wall.
