Definitions
- the present invention concerns a combination coupling for use in a water installation system in which water convey ⁇ ing unbroken pipes are made accessible for exchange and inspection by being run to the tapping point in a ductal pipe system.
- the ductal pipes are used for many different purposes. Telecommunications, antenna and power cables, •water pipes and heating pipes have been drawn in the relatively large pipes which were used years ago, often in the same ductal pipe.
- EP 005625 which, however, is additionally pro- vided with various threads capable of retaining the clam ⁇ ping ring fitting which is also contained in this junction box.
- DE 3700878 tries to solve the same problems by using a method of embedding a junction box and cobber pipes in polyurethane foam; however, this is a rather unprofessio ⁇ nal solution r and it is in fact stated in the document that the target group is the do-it-yourself-market in par ⁇ ticular.
- the purpose of the present invention is to provide a coup ⁇ ling unit which solves all the above-mentioned problems and satisfies the requirements concerning replacable pipes and accessible joints and makes it possible to register leaks in the overall system.
- a combination coupling according to claim 1 it having been found possible to manufacture an integrated unit of clamping ring fittings and built-in junction box, which also solves the problems associated with known two-component systems, since the combination coupling just consists of few parts with very small dimen- sions; this makes it i.a. much cheaper to manufacture and also entails that a rosette of standard dimensions can cover the hole in the wall in which they are attached.
- the combination coupling permits removal of the water con ⁇ veying pipe for exchange and inspection without dismant- ling the tapping unit.
- the combina ⁇ tion coupling receives both the ductal pipe and the water conveying pipe and the outlet fitting in a tight coupling, where the housing of the combination coupling according to claim 3 constitutes the part of a compression fitting which receives the liquid conveying pipe.
- dimensional restrictions may be intro ⁇ quizzed in the construction, which results in a pressure drop and thereby contribute to saving of water.
- fig. 1 shows a section through the combination coupling with inserted corrugated ductal pipe as well as water pipe
- fig. 2 is a front view of the combination coupling with a cover rosette in broken line
- fig. 3 shows a combination .coupling according to claim 5.
- the combination coupling consists of a coupling housing 1 with holes 13 for use in attachment in the building con ⁇ struction, the coupling housing is provided with an ope- ning downwardly to receive the ductal pipe 2, the opening accommodates a gasket 4 preventing water leakage exterior ⁇ ly on the ductal pipe, an opening forwardly with internal threads 10 serves to mount a tapping point optionally- with an intermediate fitting interiorly, the flexible water pipe 3 is run in the ductal pipe 2 and can be provided at its one end with an interior support bushing 6 and an outer clamping ring 5, which when applied to the water- pipe 3 engages the cone 12 Inside the coupling housing at one end and the intermediate ring 9 at the other end.
- the coupling housing 1 is provided with threads 15 exteriorly on the opening facing forwardly, to receive a sealing ring 11 with a gasket for water-type mounting against the building structure.
- the coupling housing in the present structure forms both building junc ⁇ tion box and compression fitting and is fitting-receiver.
- the complete joint will hereby consist of a minimum number of parts. Since it is made of metal, it will also be less sensitive to handling on site.
- the combination coupling provides a very great safeguard against water damage and satisfies the most recent stan ⁇ dard requirements made of water installation systems, as well as the conditions of obtaining pipe damage insurance at a reduced price, because all joints are accessible, the water conveying pipe can be exchanged and leaks, if any, can be registered by various devices in connection with the ductal pipe.
- the combination coupling is substantially made of a de- zincking-resistant brass alloy. Making it in metal pro ⁇ vides much better attachment possibilities and clamping possibilities.
- intermediate ring, support bushing and clamping screw as one part it will be possible to simplify the con ⁇ struction additionally.
- the coupling may also be con- structed as a straightway coupling.
