Abstract
Description
- The present invention relates to blow-off vents for heating systems and other similar systems. It has application in domestic central heating systems as well as heating systems for industrial applications, but could equally be used in any system which includes a blow-off vent for venting fluid, either gas or liquid, under pressure.
- It is standard practice to provide a blow-off vent for central heating systems to allow hot air and steam to escape through an external wall of a house or building. Typically the vent is in the form of a simple pipe with two 90° bends at the end so that the open end of the pipe is directed back towards the wall. This is to prevent hot air and steam from being ejected outwards away from the wall which might otherwise create a hazard, for example to people walking past.
- It can be a problem with such know vents that, because they are made from two right angle bends as well as the main pipe, the time taken, and hence the cost, to install them can be significant. Also, they tend to direct all of the hot air and steam onto a very small area of the house wall, which can mark it. They also are not particularly attractive.
- Examples of alternatives are disclosed in
US 6 289 886 ,GB 1 075 334 GB 18536 US 4461066 , in which a cowl is placed at the end of a vent pipe. - The present invention therefore provides a pipe cowl fitting comprising a pipe section terminating at an one end, and having at least one aperture at or towards said one end, and a cowl extending around said one end of the pipe section and being open in a direction away from said one end so that, in use, fluid escaping along the pipe section and through the at least one aperture will impinge upon the cowl and thereby be deflected at least partially in a direction back along the pipe section away from said one end, the pipe section is open at the other end such that it can be fitted to a vent pipe of a heating system, and the pipe section has a channel formed therein with solder in :he channel to enable attachment of the pipe cowl fitting to the vent pipe.
- Preferably the cowl is dished and has an outer edge which extends around the pipe and is spaced therefrom. Preferably said outer edge is further from the end of the pipe, in the axial direction of the pipe, than any part of the at least one aperture. Preferably the at least one aperture is defined in the side of the pipe. In this case the cowl preferably seals the end of the pipe so that the fluid can only escape through the at least one aperture.
- Preferably the at least one aperture is spaced from the end of the pipe so that the end of the pipe is in contact with the cowl over substantially the whole of its circumference. This helps to form a strong assembly-Alternatively the cowl may be supported away from the end of the pipe so that fluid can escape from the pipe through said end.
- The cowl may be supported on at least one support portion of the pipe. The support portion may have been deformed outwards to leave the at least one aperture in the pipe.
- The present invention further provides a vent system for a heating or similar system comprising a vent pipe extending substantially horizontally through an external wall of a building and terminating at an end and a fitting according to the invention, as defined in the claims.
- The present invention still further provides a method of fitting a cowl to a vent pipe for a central heating system the method comprising providing a cowl fitting according to the invention and connecting the fitting to the end of a vent pipe for the central heating system.
- Preferred embodiments of the present invention will now be described by way of example only with reference to the accompanying drawings in which:
-
Figure 1 is a perspective view of a pipe cowl fitting according to a first embodiment of the invention; -
Figure 2 is a side view of the fitting ofFigure 1 ; -
Figure 3 is a section through a pipe cowl fitting according to a second embodiment of the invention; -
Figure 4 is a section through a pipe cowl fitting according to a third embodiment of the invention; -
Figure 5 is a section through a pipe cowl fitting according to a fourth embodiment of the invention; -
Figure 6 is a section through a pipe cowl fitting according to a fifth embodiment of the invention; and -
Figure 7 is a section through a pipe cowl fitting according to a sixth embodiment of the invention. - Referring to
Figures 1 and 2 , a pipe cowl fitting 10 comprises apipe section 12 and acowl 14. The pipe section (12) is straight and of circular cross section being open at oneend 16 and closed off at theother end 18 by thecowl 14. Aridge 19 extends around thepipe section 12 close to theopen end 16. Theridge 19 is formed by deforming thepipe section 12 outwards to form a channel on the inside of the pipe section, and the channel has solder 21 in it for attaching thefitting 10 to a pipe. Thecowl 14 is dished or domed being approximately parabolic in cross section had having acircular edge 20. The closedend 18 of thepipe section 12 extends into thecowl 14 and is joined directly to the center of itsinside surface 22 by brazing, such that thecowl 14 is supported on the closedend 18 of thepipe section 12. Thepipe section 12 has a pair ofapertures 24 in its side near to the closedend 18. These are in the form of slots extending longitudinally along thepipe section 12. Thecowl 14 extends from the closed end (18) of thepipe section 12 outwards and back along thepipe section 12 away from the closedend 18 slightly further than theapertures 24. Itsedge 20 therefore extends around thepipe section 12 at a point further from theend 18 of the pipe section than any part of theapertures 24. - Referring to
Figure 3 , in use aboiler 30 of a central heating system has avent pipe 32 which extends through anexterior wall 34 and has itsend 36 projecting horizontally from thewall 34. Thefitting 10 is fitted to theend 36 of thevent pipe 32, and is heated to melt thesolder 21 inside theridge 19 thereby to attach the fitting 10 to thevent pipe 32. Hot air and steam passing through thevent pipe 32 therefore escape through theapertures 24 and impinge on thecowl 14 which acts as a baffle and dissipates energy including heat from the gas and steam, which is re-directed at least partly back along thepipe section 12 towards thewall 34. This prevents it from being ejected outwards from the wall and thereby provides protection, for example for people standing by the wall. - It will be appreciated that, instead of a solder joint, the fitting could to connected to the vent pipe by other methods, for example using a simple sealing O-ring inside the
ridge 19. - Referring to
Figure 4 in a second embodiment of the invention thecowl 40 is part conical rather than domed, with a circular flat portion 43 in its center which fits over the closedend 44 of thepipe section 46. There are fourapertures 42 towards the closedend 44 of thepipe section 46. Apart from this the second embodiment is the same as the first. - Referring to
Figure 5 , in third embodiment the fitting is similar to that in the second embodiment, but theapertures 50 in thepipe section 52 are formed as semi-circular cut-outs 53 at the closed end 54 of thepipe section 52. Thecowl 56 is therefore connected to thepipe section 52 only on support portions 58 formed between thecut outs 53, rather than around its whole circumference. - Referring to
Figure 6 , in a fourth embodiment theapertures 60 in the pipe section 62 are each formed by cutting around three sides of a portion of the pipe section 62 so as to form atab 64 in the side of the pipe section 62. Thetab 64 is joined to the rest of the pipe section 62 only at oneend 66 closest to the closedend 68 of the pipe section 62, and is bent outwards to form a supporting limb. Thecowl 70 is connected to the pipe section by joining theinside surface 72 of thecowl 70 to theouter ends 74 of thetabs 64. Thecowl 70 is supported so that it is clear of the end of the pipe section 62. Therefore steam and hot air can escape from the pipe section 62 both through theend 68 of the pipe, and through theapertures 60 in the side of the pipe. Since the cowl extends over all of the apertures including the end of the pipe, it will deflect air and steam passing through all of those apertures back towards the wall. - Referring to
Figure 7 , a fifth embodiment is the same as the fourth except that thetabs 80 in thepipe section 82 are each formed by making two parallel longitudinal cuts in from theend 84 of thepipe section 82. - Referring to
Figure 8 , in a sixth embodiment theend 90 of the pipe section 92 has small portions bent over to formbarbs 94. Thecowl 95 has holes 96 through it, and thebarbs 94 are pushed through the holes 96 and snap outwards to fit the cowl to the pipe section 92. Afurther ridge 98 on the pipe section 92 prevents thecowl 95 from sliding along the pipe section 92. This embodiment therefore provides a simple snap-fit connection between thecowl 95 and the pipe section 92.
