Flow area sudden contraction, can effectively be mixed the Non-Uniform Flow of diverse location in pipeline, so that fluid flow state
It is evenly distributed；Afterwards, cavity gradually expands identical with the diameter D of rectifying cavity 14 size up to returning to, and cavity is shunk into rectification
Send fluid line and sensor to uniform fluid stable.
Contraction section 16 can be that circular arc can also be straight line, preferably circular arc, because circular arc compares compared to straight line
Than shallower, the steady of fluid flow state is more beneficial for.
Expansion segment 18 can be that circular arc can also be straight line.Preferably, expansion segment 18 is straight line, because linear structure is more
Simply.
For example：The shape of rectifying cavity 14 can be, preferably at rectifier entrance 10, and 1/ at rectifier entrance 10
In between 4D, the diameter of rectifying cavity 14 is slowly changed into gradually tapering up in D1=3/4D, rectifying cavity 14 from D, in terms of longitudinal section, rectifying cavity
14 inside are one section of smooth circular arc；Apart from rectifier porch 1/4D to rectifier outlet 12, rectifying cavity 14 again gradually
Expand, until the diameter of rectifying cavity 14 gradually expands as D.In terms of longitudinal section, this inside of partial rectification chamber 14 is a skew lines.
In addition, rectifying cavity 14 can also set multigroup structure first shunk and expanded afterwards；At least one set can also be set first to receive
The structure that contracting is expanded after straight tube again, it is either at least one set of first to shrink straight tube further expansion again and the structure of straight tube or set at least again
One group is first shunk further expansion straight tube structure again.Purpose is so that fluid passes through multi-stage rectifying so that fluid is evenly stablized.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvements made etc. should be included within protection domain of the present utility model.
