Abstract
The invention relates to an internal-slot layered type purging nozzle for compressed air and is applicable to the field of production application of purging, drying and cooling. The internal-slot layered type purging nozzle comprises a body 1, a connector 2, a first elastic positioning and retaining ring 3, a second elastic positioning and retaining ring 4, a first-layer separated nozzle 5 and a second-layer separated nozzle 6, and a central outlet of the second-layer separated nozzle 6 is a Laval-structured air outlet 7. The internal-slot layered type purging nozzle has the advantages that consumption of the compressed air is greatly reduced; turbulent flow is minimized, and noise level is reduced; purging force is greatly improved.
Description
Technical field
The present invention relates to a kind of inside groove layer-stepping compressed air purge nozzle, be applicable to cleaning, dry, cooling production application field.
Background technology
In a lot of industries, it is very usual using compressed air to purge, and purging angle or the form of the purging open tube often flattening to reach required by pipe bending or by pipe purge operation, dry, cooling.In most cases, before open tube is installed, can not carry out strict calculating to the size of pipe, simultaneously because the Aerodynamics acquisition of knowledge is limited, thereby purge inefficiency.Adopt excessive size, can purge operation, but its defect is also apparent: excess air turbulent flow produces the meaningless energy resource consumption of injurious noise, wastes the working environment of expensive compressed air danger, has the risk of embolism, easily causes potential safety hazard.
Summary of the invention
Provide one can reduce noise in order to overcome the deficiencies of above technology, significantly reduce specific air consumption, improve the nozzle that purges cleaning power, the present invention is by realizing by the following technical solutions object: a kind of inside groove layer-stepping compressed air purge nozzle, be applicable to cleaning, dry, cooling production application field, inside groove layer-stepping compressed air comprises main body 1 by purge nozzle, connector 2, location circlip 3, location circlip 4, ground floor split shower nozzle 5, second layer split shower nozzle 6 forms, the main body that it is characterized in that described inside groove layer-stepping compressed air purge nozzle is that hollow is uncovered, connector 2, location circlip 3, location circlip 4, ground floor split shower nozzle 5, second layer split shower nozzle 6 is installed in main body 1 the inside, ground floor split shower nozzle 5, on second layer split shower nozzle 6, there is respectively the groove of varying number and size, it is a Laval nozzle.
[described main body 1 inwall has the section of being threaded, and is connected with connector 2 screw threads for fastening.Described ground floor split shower nozzle 5 is arranged on nozzle foremost, adopts location circlip 3 to locate in main body 1, is along the circumferential direction equidistantly distributed with at least one slot type air outlet on the surrounding inner headed face of ground floor split shower nozzle 5.Described inside groove layer-stepping compressed air purge nozzle, it is characterized in that described second layer split shower nozzle 6 is arranged on the second layer of nozzle, adopt location circlip 4 to locate in main body 1, on the surrounding inner headed face of second layer split shower nozzle 6, be along the circumferential direction equidistantly distributed with at least one slot type air outlet, the central outlets that it is characterized in that described second layer split shower nozzle 6 is Lavalle structure air outlet 7.
advantage of the present invention is:
The application of this nozzle has following obvious advantage:
1, compressed air consumption is significantly reduced;
2,turbulent flow is down to minimum, thereby has reduced noise level
3, purging power significantly improves.

Detailed description of the invention
Tell about operation principle and the assemble method of inside groove layer-stepping compressed air purge nozzle in conjunction with Fig. 1:
embodiment 1---operation principle:
Compressed air comprises that by purge nozzle main body 1, connector 2, location circlip 3, location circlip 4, ground floor split shower nozzle 5, second layer split shower nozzle 6 form, the main body that it is characterized in that described inside groove layer-stepping compressed air purge nozzle is that hollow is uncovered, connector 2, location circlip 3, location circlip 4, ground floor split shower nozzle 5, second layer split shower nozzle 6 are installed in main body 1 the inside, on ground floor split shower nozzle 5, second layer split shower nozzle 6, having respectively the groove of varying number and size, is a Laval nozzle.On the surrounding inner headed face of ground floor split shower nozzle 5, second layer split shower nozzle 6, be along the circumferential direction equidistantly distributed with at least one slot type air outlet, the central outlets of second layer split shower nozzle 6 is Lavalle structure air outlets 7.Its effect is by obtaining around an air-core with supersonic velocity, and its protection air film is parallel to central jet.Central gas stream is produced by a Laval nozzle.All energy of storing in compressed air are all converted to kinetic energy by this nozzle arrangements, and can not make air lateral magnification when by nozzle.Air column stream protective sleeve around utilizes surrounding air to prevent that it from slowing down, and air is fully used, and produces evenly, stable, lamina air flow smoothly, eliminates the high noisy turbulent flow being produced by open tube.
embodiment 2---each parts assembling method:
Inside groove layer-stepping compressed air is that hollow is uncovered by the main body of purge nozzle, connector 2, location circlip 3, location circlip 4, ground floor split shower nozzle 5, second layer split shower nozzle 6 are installed in main body 1 the inside, main body 1 inwall has the section of being threaded, and is connected with connector 2 screw threads for fastening.Described ground floor split shower nozzle 5 is arranged on nozzle foremost, adopts location circlip 3 to locate in main body 1, and second layer split shower nozzle 6 is arranged on the second layer of nozzle, adopts location circlip 4 to locate in main body 1.
