Abstract
The utility model relates to a flow guide pipe which comprises a flow guide pipe body, wherein the flow guide pipe body is connected end to end, and the flow guide pipe body is hollow; an external ring of the flow guide pipe body is provided with a liquid inlet communicated with the inside of the flow guide pipe body; an inner ring of the flow guide pipe body is provided with a plurality of liquid outlets communicated with the inside of the flow guide pipe body at equal intervals; the apertures of the liquid outlets are sequentially increased in the direction from being close to the liquid inlet to being far away from the liquid inlet. According to the flow guide pipe, a liquid medium enters a test piece box through the plurality of liquid outlets which are formed at the equal intervals, so that the uniformity of the liquid medium entering the test piece box is ensured, and the temperature uniformity inside the test piece box can be greatly enhanced.
Description
Technical field
The utility model relates to a kind of mozzle, relates 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, carry out freezing to concrete sample, when reaching after 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 multiple concrete samples there are differences, thereby increased test error.
Utility model content
The utility model object is to provide a kind of can ensure that liquid medium enters the inhomogeneity mozzle in test specimen case in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of mozzle, comprises mozzle body; Described mozzle body head and the tail connect; 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 multiple liquid outlets that communicate with mozzle body interior; The aperture of described liquid outlet is from increasing successively close to the direction away from inlet.
Preferably, the cross section of described mozzle body is square.
Preferably, described mozzle body head and the tail connect into square.
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 utility model compared with prior art has following advantages:
Mozzle of the present utility model, liquid medium enters in test specimen case by the liquid outlet of multiple equidistant arrangements, has ensured that liquid medium enters the homogeneity in test specimen case, can greatly improve the homogeneity of test specimen the temperature inside the box.
Brief description of the drawings
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
The structural representation that accompanying drawing 1 is mozzle of the present utility model;
Another visual angle structural representation that accompanying drawing 2 is mozzle of the present utility model;
Wherein: 1, mozzle body; 2, inlet; 3, liquid outlet.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Described in the utility model 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 multiple liquid outlets 3 that communicate with mozzle body interior; The aperture of described liquid outlet 3 is from close to increasing successively away from the direction of 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.
When 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 multiple equidistant arrangements, ensure that liquid medium enters the homogeneity in test specimen case, can greatly improve the homogeneity of test specimen the temperature inside the box.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
