Definitions

  • the invention relates to a discharge structure for closed gas appliances.
  • Such discharge structures form the main component of a roof terminal or wall terminal for, for instance, heating boilers and comprise a line for the supply of combustion air and a line for the exhaust of combustion gasses.
  • the discharge structure then further comprises a supply means for combustion air, such as a supply hood, forming the connection between the outside air and the supply line for combustion air, and a flow-promoting exhaust means for combustion gasses, such as a draught hood, forming the connection between the combustion gas exhaust line and the outside air.
  • the exhaust means is situated at a greater distance from the space in which the gas appliance is located than the supply means, that is to say, in a vertical arrangement of the discharge structure, above the supply means.
  • the venting passage forms a direct connection for combustion air between the main passage, formed by the air supply means, and the outside air. Too high a pressure built-up inside the air supply means, in particular the air supply hood, which could form a disturbance for the burner or, as a consequence of air streams caused thereby, for the efficiency of the appliance due to losses during standstill, are hereby controlled.
  • Discharge structures are often completely adapted to the brand and type of the gas appliance onto which they are to be fitted or to a certain group of gas appliances with a defined working area or working range width.
  • the discharge structures are supplied in new building and renovation projects in the composition and with the dimensions in which they are about suitable for mounting in the work.
  • the various components are herein connected to each other in a usually permanent manner in the factory, for instance by being welded, riveted or glued, in a manner which is usually very labour-intensive.
  • the various standards may prescribe a minimum height above the roof for the combustion gas exhaust means and the exact position of the gas appliance below the roof, it can be necessary that the discharge structure is given a certain surplus length in order to, in the absence of simple possibilities for adaptation, in the case of deviations in measurement in the work, yet be able to fall within these standard values or fitting measures. It is also a drawback that the selection of materials for the various components of the discharge structure will be subject to restrictions, due to the manner in which the components are connected to each other, for instance when a threaded connection is used. Another drawback to the known discharge structure is that alterations in the discharge structure after a period of use, necessary for for instance replacement of components thereof, is difficult and usually impossible due to the way in which those discharge structures have been assembled. Consequently, the entire discharge structure will often need to be replaced.
  • retaining means for axially keeping together in a mechanical manner the components of the discharge structure.
  • these retaining means such as for instance abutment means no special tools are required, except for instance a screwdriver, for assembling the discharge structure, as a consequence of which this could be done at sales locations and even at the site by junior or unskilled persons.
  • this leads to a greater freedom of choice of materials for the various components, because for instance the suitability of the various components for being welded together need no longer be taken into account.
  • the discharge structure can be assembled at sales locations or at the site, the gas exhaust pipe and the casing can also be adapted to the dimensions at the site. This can be the case both in new buildings or renovation and in replacement after a period of use.
  • the retaining means preferably comprise an adjustable retaining portion on the inner end and a retaining portion on the outer end of the inner pipe means, which between them stay, in series, the combustion gas exhaust means, the combustion air supply means and the casing.
  • the first abutment means are arranged for detaining the combustion gas exhaust means in outward direction
  • the combustion gas exhaust means being provided with second abutment means for detaining the combustion air supply means in outward direction
  • the combustion air supply means being provided with third abutment means for detaining the casing in outward direction
  • the discharge structure further comprising inner abutment means, which can be stayed at a chosen location on the gas exhaust pipe and which form the adjustable retaining portion for detaining the casing in inward direction.
  • assembling the discharge structure according to the invention is very simple.
  • the assembler or installer takes the gas exhaust pipe and then consecutively slides on the combustion gas exhaust means or hood, the combustion air supply means or hood, possibly an insulating sleeve and the casing from the inner end of the gas exhaust pipe, until the combustion gas exhaust means is detained at the outer end of the gas exhaust pipe by the retaining portion.
  • a returning movement of these components is thereafter prevented by the adjustable retaining portion, also referred to as the inner abutment means.
  • the assembler or installer has been able to make the gas exhaust pipe to size by means of for instance a saw.
  • the discharge structure is then ready for arrangement in the work en connection to the gas appliance. Because the important measurements have been taken earlier and have been worked into the discharge structure, this instalment can be carried out smoothly, so that the workspeed can be increased.
  • the first and the inner abutment means are preferably executed such that they are not only active in axial direction, but also in radial direction, in order to stay the various components, which have to be kept concentrically relative to each other, in radial direction relative to each other.
  • the inner pipe 20 passes on its outer end, in this case its upper end, via an annular shoulder 22 into a portion having a larger diameter 21. What is especially important here is the shoulder 22, of which the function will be further discussed below.
  • the outer pipe 30 consists of two parts 30a and 30b.
  • the pipe part 30a herein has a length, corresponding to the regulations concerned.
  • the outer pipe 30b can simply be adapted in length to the situation in situ.
  • pipe part 30a is provided with a storm collar 39', and also with a retaining ring 39'' situated therein, and active in radial direction for keeping the pipe part 30b in position relative to pipe part 30a.
  • An insulating sleeve 60 is placed around the inner pipe 20, which insulating sleeve extends from the lower end of the outer pipe 30 up to the gas exhaust hood.
  • the retaining ring 70 When the outer pipe has been installed, the retaining ring 70 is installed, which retaining ring is provided with two rings 71 and 73, placed concentrically relative to each other and being connected to each other by means of small radial partitions 72. These small radial partitions between them leave clear sufficient flow openings for the combustion air supplied to a manifold, not shown in more detail, which is connected to the inner end of the annular space in an almost sealing manner, and which connects on its other side to the air supply and the gas exhaust of the gas appliance.
  • the inner ring 73 On its upper end, seen in figure 1, the inner ring 73 is provided with a locating edge 74, with which the insulating sleeve 60 is positioned relative to the inner pipe 20.
  • the ring 71 is formed such that it connects smoothly onto the outer pipe 30b.
  • a ring 80 closely fitting onto the inner pipe 20, is slid on until it abuts retaining ring 70 and then secured by means of tipped screws 81 on the inner pipe 20.
  • the exhaust hood 50, the supply hood 40, the outer pipe 30 and the insulating sleeve 60 are retained between the shoulder 22 and the clamping ring 80.
  • the discharge structure is turned over and the lid 52 is secured onto the exhaust hood 50. This can for instance be done by means of screws or by means of a snap connection.
  • the ring 200 can also be applied as a optional component on the previously mentioned short circuit between the passage from the outside to the annular line and the ambient air to vent the surplus of air, if desired.
  • the ring 200 is provided with depending projections 202 which are spaced from each other in circumferential direction, and between them leave clear radial passages 203, through which a surplus of air can flow from within the air supply hood towards the outside, around the downwardly extending ring 157.
  • the upper part 301 comprises a casing 311 and the lower part 302 comprises a casing 312.
  • Figure 3A shows the connection between both parts.
  • the lower part 302 is formed with a U-slot 310, formed by an inner raised roundgoing edge 304 and an outer raised edge 306 projecting above that.
  • This outer edge 306 is provided at regular intervals with projections 330 which are each provided at the radial outer end with a shoulder 309.
  • the upper part 301 is provided with a roundgoing, downwardly projecting edge 303, and on the radial outer side thereof, via radially projecting bodies 308 arranged at regular intervals, provided with a roundgoing ring 307.
