Description
Technical field
The present invention relates to a kind of receive element for fluid media (medium) for connecting at least two
Adapter, such as connecting two pipelines for fluid media (medium), this adapter have for
The the first connection end connecting the first receiving element and be used for connection the second receiving element second is even
Connect end, and adapter can be flow through by fluid media (medium) between first and second connection end.Fluid
Medium this can connect from first to second end flow over there or on the contrary from second connect end to
First connects end flows over there.The most special for the receiving element of fluid media (medium)
Do not refer to the pipeline for leading fluid media (medium) or for the casing of fluid media (medium) or for fluid
The measuring element of medium.Pipeline is also referred herein to hoseline or plastic flexible pipe.Using according to this
When the adapter of invention is used for connecting at least one pipeline, being below also referred to as this adapter is that pipe connects
Device.Pipeline can be inserted into the first connection end or second of tube connector aptly and connects in end and at this
In particularly lockable.
Background technology
The tube connector of above-mentioned pattern is known with different forms of implementation in practice.Especially
It is to have problems, i.e. at low temperature in the pipeline for leading water or water-bearing media and tube connector
Time fluid media (medium) freeze, volumetric expansion.Due to such volumetric expansion or owing to occurring therewith
Pressure, pipeline and tube connector can damage or even completely destroy.In practice in order to solve
This problem people have been proposed that various different measure.But these measures are most and unsatisfactory.
Use so-called SCR method (SCR) in the car, in order to reduce useless
The nitrogen content of gas.Aqueous urea liquid is used in the range of this SCR method.Particularly
The problems referred to above also occur in the urea liquid that this is aqueous.The urea liquid class aqueous when low temperature
It is similar to water freeze, volumetric expansion, and the pipeline of SCR system, adapter etc. are by corresponding
Pressure increase can damage or destroy completely.By actual it is known that in such SCR system
In automobile stop after evacuate guide medium pipeline.Thus be excluded that aqueous medium is at pipeline
In freeze.But it is the biggest and error-prone that this processing method expends.
