  • double-walled pipe systems or pipe systems are increasingly being used, on the one hand to safely discharge the exhaust gas produced during combustion and, on the other hand, to supply the supply air required for combustion through a space-saving pipe system, with the supply air being preheated by the exhaust gas to save energy.
  • Such known line systems consist of an outer line component and an inner line component surrounded concentrically by the outer line component, wherein the line components can be pipelines with a circular cross section.
  • An externally accessible measuring point is available to the pipeline systems.
  • an antiseptic cap that has a cap holder.
  • the cap holder has an opening through which a Luer connector is inserted into the cap, which in turn is connected to an infusion line.
  • the Luer connector is surrounded in sections by the cap holder.
  • a tapered section extends from the Luer connector towards the bottom of the cap holder.
  • the antiseptic cap has a cap which is arranged inside the cap holder and which comprises a threaded section which is screwed to the Luer connector.
  • a boiler connector for connecting boilers to a measuring point system of the type mentioned is, for example, from DE 100 53 067 C1 known.
  • the measuring point system is designed on a boiler connection piece and has an internal exhaust gas line and an external air supply line arranged concentrically and at a distance from it.
  • the exhaust pipe also has a pipe section designed as a measuring connector which extends radially from the outside of the exhaust pipe.
  • the exhaust pipe is rigidly connected to the supply air pipe via radial webs and the measuring nozzle.
  • the pipe section designed as a measuring nozzle is led outwards from the supply air line and closed by a plug. After removing the plug, a probe for taking smoke gas samples can be inserted into the exhaust pipe through the measuring nozzle.
  • the invention is based on the object of creating a solution which, in a structurally simple manner, comprises an exhaust system with a boiler connection piece comprising a measuring point system which is inexpensive to manufacture and which also guarantees improved safety in the event of a leak in the plug or closure which closes an opening of a measuring port of an inner line component surrounded by an external line component.
  • the object is achieved in that a gap is formed between the inner line component measuring opening and the outer line component, the at least one closure element having an elongated body which, when the at least one is attached Closure element on the outer line component extends at least in sections into the at least one measuring port and which both the at least one outer line component measuring opening and the at least one inner line component measuring opening is designed to be sealing.

  • the invention provides that the at least one measuring port ends at a predetermined distance from the at least one external line component measuring opening.
  • the measuring nozzle could extend into the outer line component measuring opening - however, the design so that the measuring nozzle ends at a predetermined distance from the outer line component measuring opening ensures that there is a sufficient gap in every case that in the event of a leak in the inner line component measuring opening through the inner line component flowing fluid, such as exhaust gas, flows into the outer conduit component.
  • a sealing section is formed on a first longitudinal end of the elongated body of the at least one closure element, which is arranged within the at least one measuring connector when the at least one closure element is attached to the outer line component and on which at least one sealing lip which extends around the elongate body and protrudes therefrom is integrally formed and which is designed to be elastically deformable.

  • the closure element there are defined positions for the closure element, so that when a corresponding marking is applied in an area of the closure element that is visible from the outside, it can be recognized immediately whether the closure element is in a locked and secured position for sealing the system.
  • a structurally simple possibility for secure locking and thus sealing can be implemented in an embodiment of the invention in that the locking mechanism has at least one locking attachment which is formed on the elongated body of the at least one closure element, the at least one locking projection in the locking position of the at least one closure element being arranged to reach behind the edge of the at least one external line component measuring opening, whereas the at least one locking projection in the opening position of the at least one closure element is in alignment with an enlarged one Area of the at least one external line component measuring opening is arranged.

  • only one locking projection is formed on the elongated body 10 of a respective closure element 2. This is because it is sufficient if only one of the locking lugs 20a, 20b engages behind the edge 21 of the associated external line component measuring opening 9 in the locking position of the respective closure element 2 (see, for example, FIG Figure 15 ).
  • one of the two locking lugs 20b serves to noticeably indicate to an operator that the locking position has been reached.

  • the respective external line component measuring openings 9 each have an enlarged area 22 (see, for example Figures 6 and 18th ), which is important for dismantling a respective closure element 2 or for taking samples.
  • the two locking lugs 20a, 20b are arranged in alignment with the widened area of the respective external line component measuring opening 9, so that the Closure element 2 can be pulled out of the outer line component measuring opening 9.

If the sealing section 12 can no longer fulfill its sealing function, the fluid flowing through the inner line component 4 does not flow into the external environment but into the outer line component 3, which significantly increases the safety of the measuring point system 1 compared to known systems.
  • a respective measuring nozzle 6 ends at a predetermined distance 25 from the associated external line component measuring opening 9, although this is not absolutely necessary, because the measuring nozzle 6 could also end inside the external line component measuring opening 9 as long as the sealing lip element 18 seals the external line component measuring opening 9 and there is a gap 24 between the measuring connector 6 and the sealing lip element 18, through which the fluid flowing in the inner line component 4 can flow from the measuring connector 6 into the space between the outer line component 3 and the inner line component 4.
  • a respective locking projection 20a, 20b has a holding surface 26 (see, for example, FIG Figures 9 and 19th ), which is arranged radially at the end on a respective locking projection 20a, 20b, and a respective external line component measuring opening 9 on the inside of the external line component 3, a blocking projection 27 (see FIG Figures 18 and 19 ) on.
  • a respective locking projection 20a, 20b has a rising tightening surface 28 which is connected to the holding surface 26, which is designed to be sloping in relation to the rising tightening surface 28. Consequently, when the closure element 2 is rotated from the open position into the locking position, an operator has to exert increasing force in order to move the attraction surface 28 over the blocking projection 27.
  • sealing section 12 can be designed with at least one sealing lip 14 in such a way that a sealing section 12 inserted through the external line component measuring opening 9 into the measuring connector 6 can be non-positively connected to the measuring stub 6 so that the holding force of the non-positive connection ensures the tightness of the measuring point system 1 without locking the closure element 2 being necessary for this.
