Description
Technical field
The present invention relates to flange arrangement, in particular to a kind of no-welding type flange arrangement for shock tube.
Background technology
Shock tube is to generate high speed shock wave by height pressure difference moment, and then substance is heated using shock wave, is pressurizeed
To obtain the experimental provision of high adiabatic flame temperature and pressure, since shock tube can provide more broad experiment condition,
It is therefore widely used in perhaps multi-disciplinary research.
Shock tube carries out uniform, non-constant entropy, adiabatic compression using incident and reflected shock wave to substance, so the generation of shock wave
And operation conditions plays a crucial role shock tube experiment.The major parameter for influencing shock wave operation has：Tube body straight line
Degree, tube body concentricity and inner surface of tube body roughness.It therefore, should be in shock tube in order to ensure the levels of precision of shock tube experiment
Design processing in improve straightness, concentricity and the inner surface of tube body roughness of tube body as possible.
In the processing and manufacturing of shock tube, since shock wave length of tube is longer, it usually needs tube body is divided into several sections, is then adopted
It is attached with flange arrangement.Traditional flange is all to be mounted on tube body by welding, and the high temperature of welding process must
The bending of tube body and ring flange can so be caused, so as to reduce the straightness of shock tube tube body and concentricity, influence shock wave
Operation.
