Description
Technical field
The present invention relates to the cleaning by high pressure water jet technology field, particularly relate to a kind of cavitation jet nozzle.
Background technology
The cavitation jet nozzle is to improve a kind of water jet form nozzle grow up according to High pressure water jet nozzle, and the cavitation jet of its formation can be used for underwater cleaning, have environmental protection, energy-conservation, efficient, without characteristics such as burn into are easy to operate.But the Nozzle throat of traditional cavitating nozzle is single constant, only directly locates to form Peak Flow Rate at larynx, produces the stream pressure, but can not derive the cavitation bubble of optimum efficiency.Therefore, the present invention proposes a kind of novel cavitation jet nozzle.
Summary of the invention
Technical problem to be solved by this invention provides a kind of cavitation jet nozzle, is used for solving the problem that traditional cavitating nozzle can not derive the cavitation bubble of optimum efficiency.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of cavitation jet nozzle, comprise a water inlet, delivery port and be connected at least two-stage jet pipe that connects, the larynx footpath of jet pipes at different levels increases progressively according to progression, and described water inlet is connected with first order jet pipe, and described delivery port is connected with the afterbody jet pipe.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the shape of described water inlet and described delivery port is dihedral.
Further, when the shape of described water inlet and described delivery port was dihedral, the angle of described water inlet was 15 °, and the angle of described delivery port is 30 °.
Further, when the shape of described water inlet and described delivery port was dihedral, described cavitation jet nozzle adopted the two-stage jet pipe.
Further, described water inlet is shaped as dihedral, and described delivery port is shaped as sphere.
Further, when described water inlet is shaped as dihedral, and described delivery port is when being shaped as sphere, and the angle of described water inlet is 40 °, and described delivery port is shaped as the sphere of 10 centimetres of radiuses.
Further, when described water inlet is shaped as dihedral, and described delivery port is when being shaped as sphere, and described cavitation jet nozzle adopts three grades of jet pipes.
Further, described water inlet is threaded, and it is used for described cavitation jet nozzle is connected with other parts.
The invention has the beneficial effects as follows: the present invention is by amplifying the classification in nozzle throat footpath, produce Peak Flow Rate behind the jet pipe that current are directly increased progressively by larynx, simultaneously in the situation that mesolow power current (0-15Mpa), produce the negative pressure pulsation water jet in the larynx footpath by the classification amplification, thereby bring out a large amount of cavitation bubbles.Cavitation bubble under this state has the maximum function of degrading, so the cavitation jet that produces of the present invention is to the erosion of material effects face or degrade, and comparable high-pressure water jet increases several times on effect.
Description of drawings
Fig. 1 is the structural representation of the dihedral secondary cavitation jet jet pipe of the embodiment of the invention one;
Fig. 2 is the structural representation of three grades of cavitation jet jet pipes of sphere of the embodiment of the invention two.
In the accompanying drawing, the list of parts of each label representative is as follows:
1, water inlet, 2, delivery port, 3, the one-level jet pipe, 4, the secondary jet pipe, 5, three grades of jet pipes.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present invention and feature are described, institute gives an actual example and only is used for explaining the present invention, is not be used to limiting scope of the present invention.
As shown in Figure 1, embodiment one is a kind of dihedral secondary cavitation jet nozzle, comprise a water inlet 1, delivery port 2 and be connected one-level jet pipe 3 and the secondary jet pipe 4 that connects, and the larynx of secondary jet pipe 4 footpath is larger than the larynx footpath of one-level jet pipe 3.Described water inlet 1 is connected with one-level jet pipe 3, and described delivery port 2 is connected with secondary jet pipe 4.
The shape of water inlet 1 described in the embodiment one and described delivery port 2 is dihedral, and the angle of described water inlet 1 is 15 °, and the angle of described delivery port 2 is 30 °.
As shown in Figure 2, embodiment two is a kind of spherical three grades of cavitation jet nozzles, and it comprises a water inlet 1, delivery port 2 and be connected one-level jet pipe 3, secondary jet pipe 4 and the three grades of jet pipes 5 that connect, and increases progressively successively from the larynx footpath of 3 to three grades of jet pipes 5 of one-level jet pipe.Here, described water inlet 1 is connected with one-level jet pipe 3, and described delivery port 2 is connected with three grades of jet pipes 5.
Three grades of cavitation jet nozzles of the sphere of embodiment two, its water inlet 1 is shaped as dihedral, and delivery port 2 is shaped as sphere.And the angle of described water inlet 1 is 40 °, and described delivery port 2 is shaped as the sphere of 10 centimetres of radiuses.
For embodiment one and embodiment two, the cavitation jet nozzle utilizes first die casting, and lathe fine finishining forms again, and described water inlet 1 all is threaded, and it is used for described cavitation jet nozzle is connected with other parts.In actual applications.
Embodiment one is identical with the operation principle of embodiment two: by the classification in nozzle throat footpath is amplified, make current pass through to produce Peak Flow Rate behind the jet pipe, simultaneously in the situation that mesolow power current (0-15Mpa), be amplified in generation negative pressure pulsation water jet in the larynx footpath by classification, thereby bring out a large amount of cavitation bubbles.Under the effect of the angle of flare of water inlet and delivery port, can strengthen jet and the shearing force of water body on every side, produce most effectively a large amount of cavitation bubbles.Current enter the water inlet of dihedral secondary cavitation jet nozzle and spherical three grades of cavitation jet nozzles by mesolow power (0-15Mpa), in one-level larynx footpath, secondary larynx footpath and spherical three grades of larynxs footpath, produce the underbalance pulse water jet, penetrate a large amount of cavitation bubbles from dihedral secondary effluent mouth or spherical three grades of delivery ports, finally reach and degrade function.
When water temperature one timing, the dihedral secondary cavitation jet nozzle of embodiment one is suitable under the environment of current disorder, and three grades of cavitation jet nozzles of the sphere of embodiment two are suitable for producing more cavitation bubble under the metastable environment of current.
Among these two embodiment, all be according to the shape of water inlet and delivery port and angle different adjust the classification number of times in nozzle throat footpath and larynx directly than, such as the size that indicates among Fig. 1 and Fig. 2, namely be can make corresponding cavitation jet nozzle in the situation that in low water flow pressure (0-15Mpa) produce a considerable number of cavitation bubble.
Two kinds of nozzle arrangements design among above-mentioned two embodiment and key parameter can be under the effects of mesolow waterpower, generation negative pressure pulsation and contain the water jet of a large amount of cavitation bubbles in cavitation jet nozzle throat footpath.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
