Definitions

  • the invention relates to a quick release for exhaust pipes, especially in SCR applications.
  • AdBlue a reducing agent that has extreme creep properties. Seals in the exhaust area are very difficult to seal, previously such exhaust pipes were welded directly to the SCR catalyst tube or bolted with elaborate screw.
  • Object of the present invention is to avoid the above-mentioned disadvantages and to provide a tight connection, which is easy and quick to open and close.
  • the object of the present invention is achieved by a quick release according to claim 1.
  • the solution according to the invention is tight against Adblue, DEF or AUS 32 according to ISO 22241, allows a uniform force distribution or a well-defined force in the sealing area. The retightening in case of subsidence of the seals is possible.
  • the threaded sleeve solution is suitable for any type of exhaust system, since it is also resistant to all common fuels and their condensates and to all types of exhaust gases from internal combustion engines.
  • An advantage of the screw sleeve quick release is that he has a quick and easy assembly and disassembly of the exhaust system in the vehicle, in particular for repair work or for service work on the SCR catalytic converter and exhaust pipe of the mixing section.
  • Another advantage is the fact that during maintenance the closures can be reused because they are part of the exhaust gas components. All you have to do is replace the seals. It is also advantageous that the ffermuffen shame are much easier to handle in handling, as to be welded components. Another advantage is that the ffermuffenates with known pipe socket or pipe profiles can be used.
