Abstract
The invention discloses a flow guide pipe which comprises a flow guide pipe body connected end to end and is hollow, wherein a liquid inlet communicated with the interior of the flow guide pipe body is formed in an outer ring of the flow guide pipe body; a plurality of liquid outlets communicated with the interior of the flow guide pipe body are formed in an inner ring of the flow guide pipe body at equal intervals; the apertures of the liquid outlets are increased in a direction from the liquid outlets close to the liquid inlet to the liquid outlets far away from the liquid inlet in sequence. According to the flow guide pipe, a liquid medium enters a test piece box through the plurality of liquid outlets arranged at equal intervals, so that the uniformity of the liquid medium entering the test piece box is guaranteed and the uniformity of the temperature in the test piece box can be greatly improved.
Description
Technical field
The present invention relates to a kind of mozzle, relate in particular to a kind of for the mozzle on freezing-thawing test machine.
Background technology
In order to detect the anti-freezing property of concrete sample, need simulating nature circle variation of ambient temperature, concrete sample is tested, be called freezing-thawing test.In prior art, freezing equipment and thawing equipment separate, temperature-fall period will be placed on concrete sample in household freezer (refrigerant is air), after completing, need manually from household freezer, to take out test specimen, then putting into thawing equipment (aqueous fusion) melts, and then manually take out test specimen, put into household freezer and carry out next circulation, concrete sample is placed in back and forth and freezes, melts equipment, take a lot of work, require great effort, labour intensity is large, and the concrete time in transfer process will with ambient atmosphere environmental exposure, increased test error.
The appearance of freezing-thawing test machine well solves the above problems.Freezing-thawing test machine utilizes refrigerating plant and water pump to filling liquid medium in test specimen case, to concrete sample, carry out freezing, after reaching the temperature needing, refrigerating plant cuts out, utilize heating arrangement and water pump to filling liquid medium in test specimen case, concrete sample is melted, complete a freezing and thawing cycle, repeat above-mentioned steps, enter next freezing and thawing cycle.But in the freezing-thawing test machine of prior art, liquid medium enters in test specimen case by single inlet, due to stopping of concrete sample, can cause the non-uniform temperature in test specimen case, cause the temperature between a plurality of concrete samples there are differences, thereby increased test error.
Summary of the invention
Technical matters for above-mentioned existence, the object of the invention is: proposed a kind ofly can guarantee that liquid medium enters the inhomogeneity mozzle in test specimen case.
Technical solution of the present invention is achieved in that a kind of mozzle, comprises mozzle body; Described mozzle body connects from beginning to end; Described mozzle body hollow; On the outer shroud of described mozzle body, have the inlet communicating with mozzle body interior; The interior ring equal intervals of described mozzle body has a plurality of liquid outlets that communicate with mozzle body interior; The aperture of described liquid outlet increases successively from the direction close to away from inlet.
Preferably, the cross section of described mozzle body is square.
Preferably, described mozzle body connects into square from beginning to end.
Preferably, described inlet is opened on the outer wall of mozzle body; Described liquid outlet is opened on the inwall of mozzle body.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Mozzle of the present invention, liquid medium enters in test specimen case by the liquid outlet of a plurality of equidistant arrangements, has guaranteed that liquid medium enters the homogeneity in test specimen case, can greatly improve the homogeneity of test specimen the temperature inside the box.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
The structural representation that accompanying drawing 1 is mozzle of the present invention;
Another visual angle structural representation that accompanying drawing 2 is mozzle of the present invention;
Wherein: 1, mozzle body; 2, inlet; 3, liquid outlet.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Of the present invention a kind of mozzle as shown in accompanying drawing 1,2, comprises mozzle body 1; Described mozzle body 1 head and the tail connect; Described mozzle body 1 hollow; On the outer shroud of described mozzle body 1, have the inlet 2 communicating with mozzle body 1 inside; The interior ring equal intervals of described mozzle body 1 has a plurality of liquid outlets 3 that communicate with mozzle body interior; The aperture of described liquid outlet 3 increases successively from the direction close to away from inlet 2.
While being applied in freezing-thawing test machine, the cross section of described mozzle body 1 is square; Described mozzle body 1 head and the tail connect into square; Described inlet 2 is opened on the outer wall of mozzle body 1; Described liquid outlet 3 is opened on the inwall of mozzle body 1.
During use, inwall on the outer wall of mozzle body 1 and between freezing-thawing test machine test specimen fixes, the water pump of freezing-thawing test machine joins by pipeline and inlet 2, liquid medium enters in test specimen case by the liquid outlet 3 of a plurality of equidistant arrangements, guaranteed that liquid medium enters the homogeneity in test specimen case, can greatly improve the homogeneity of test specimen the temperature inside the box.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
