Definitions

the invention relates to a detachable pipe connection for sealing exhaust pipes of internal combustion engines, with a flange with a chamber for receiving a Beaded ring-shaped disc.
Exhaust pipes from internal combustion engines usually consist of several Single pipes that are directly connected to each other on the vehicle and against Leakage of media to be sealed. It becomes like a sleeve insertable pipes are used, which are attached via pipe clamps. Moreover, it is known to arrange flange surfaces at the pipe ends, between which seals are arranged and z. B. screws are connected.
DE OS 1959 666 shows a detachable pipe connection with flange surfaces, in which an annular helical spring is axially clamped between the flange surfaces.
the coil spring seals directly on the pipe surfaces.
an elastic sealing ring made of elastomeric material can be connected upstream of the coil spring.
Exhaust systems in modern engines have to be designed for ever higher temperatures and longer operating times. Sealing bodies made of non-metallic materials no longer meet the loads. Sealing directly on the exhaust pipes also often poses problems because the pipes do not have the necessary surface topography. Inadequate sealing means that oxygen gets into the exhaust gas flow. This oxygen enrichment is detected by the engine electronics and immediately causes fuel enrichment in the fuel-air mixture. As a result, more air-polluting substances flow into the atmosphere.
a 1 is a flange seal made of metal for high pressures and Temperatures.
a disc made of coaxially corrugated sheet metal has flanged soft metal sealing washers at the two end regions. When the flanges are screwed together, the soft metal is plastically deformed and seals in the chamber.
the disadvantage of this system is that after each Loosening the connection a new washer must be used.
the invention has for its object a pipe connection for sealing To create exhaust pipes that can be used at high temperatures and also after repeated loosening of the connecting parts can still be used so that a Micro-sealing is guaranteed.
FIG. 1 shows a pipe connection 1 according to the invention
the flange 3 has an annular chamber 5, in which one with Beads 6 provided disc 7 is arranged.
the disc 7 lies on the flanks 8, 9 and at the bottom 10 of the chamber 5.
the beads 6 are both in the area of the bottom 10 also provided in the area of the flanks 8.9.
the counter flange 4 has an axially directed projection 11, which is dimensioned such that it can be inserted into the chamber 5 and the beads axially and radially with a defined sealing pressure for bearing against both the plug body 11 and the bottom 10 and on the flanks 8 , 9 brings.
suitable fastening means for example a screw connection
the flanks can be joined together and a seal is created via the beads 6 in both the radial and the axial direction.
This series connection of beads 6 creates several sealing zones, which ensures micro-sealing, regardless of the surface properties of the pipes 2, 2 '. As shown in FIG.
FIG. 2 shows an alternative embodiment of the invention, in which a ring 14 is pressed into the chamber 5.
the counter flange 4 ' can be formed symmetrically to the flange 3.
a disk 7 'according to FIG. 2 has been used, which interacts with the flanges 3, 4 disclosed in FIG.
the pipe connection can Assembly work on the motor vehicle can be easily solved and reassembled.
