Abstract
Provided is a high-density flow nozzle. The high-density flow nozzle comprises a nozzle body. A spouting cavity is formed in the nozzle body, spouting orifices are formed at the bottom end of the spouting cavity, a vortex disk which divides the spouting cavity into an upper and a lower cavity is arranged at the middle portion of the spouting cavity. The vortex disk is a circular disk, a plurality of gaps are formed in the vortex disk from outside to inside around a center of a circle. Liquid passes the vortex disk and disperses a main stream to four tributaries revolving out, wherein the four tributaries fully rotate and mix along the wall surface of a transition cavity, and eventually sprout through an inclined plane nozzle, and impurities are separated at the upper position of the vortex disk effectively. The impurities are prevented from entering a lower cavity, jet flow effect and angle change are prevented effectively, and therefore high-density even jet flow is achieved, wherein the jet flow density is high and the jet flow spouts evenly.
Description
Technical field
The utility model relates to a kind of nozzle for the mechanical atomization injection.
Background technology
Flow nozzle in the market generally mostly is spiral nozzle, the nozzle body bottom is leptospira structure, the liquid in rotation that drive enters is eddy current, then spray by jet, prior art is higher to dimensional requirement and the ratio of precision of jet, it is comparatively complicated to make this flow nozzle technique, also higher to the requirement of the spiral on the nozzle body, size slightly has not on affecting the effect of injection, does not reach needed spray angle and the scope of producing, in addition when spraying, easy jam impurity further affects jeting effect in the helical structure of injection body, makes the liquid dispersion of its injection inhomogeneous, density is low, haves much room for improvement.
Summary of the invention
The utility model provides the hyperpycnal flow flow nozzle that a kind of injection density is high, injection evenly, effectively prevents the impurity jam for the deficiencies in the prior art.
The utility model is for solving the problems of the technologies described above, provide following technical scheme: a kind of hyperpycnal flow flow nozzle, comprise nozzle body, offer spray chamber on the nozzle body, the spray chamber bottom is provided with jet, it is characterized in that being provided with an eddy flow tray at the spray chamber middle part is divided into up and down two chambers with spray chamber, described eddy flow tray is circular discs, offers from outside to inside several breach around the center of circle.
As further improvement of the utility model, described breach is square, evenly offers around the center of circle.Make eddy flow tray consist of a rotating vane shape by this kind setting, make it more meet the eddy flow principle, add the maelstrom effect.
As preferably, described breach is 4.By this kind setting, make evenly four breach of distribution of rotating disc, meet the fluid engineering principle, accelerate swirl velocity.
As preferably, the lower chambers diameter is less than lower chambers.Make the current by eddy flow tray enter lower chambers compression eddy flow by this kind setting, strengthen the injection dynamics, improve jeting effect.
Described spray chamber bottom is provided with jet.
As further improvement of the utility model, the jet center offers the divergent contour through hole.Make spray regime wider by this kind setting, density is larger.
As preferably, through hole is up-small and down-big conical bore.Make the swirl injection effect better.
The beneficial effects of the utility model: liquid is through eddy flow tray in the utility model, the tributary that main flow is separated into four roads rotations and goes out, tributary, four roads fully rotates mixing along the adapter cavity wall, send forth finally by the inclined-plane spout, and effectively impurity is intercepted above eddy flow tray, prevent that it from entering lower chambers, effectively prevent the change of jet effect and angle, thereby obtain highdensity Uniform jet, its jet density is high, jet sprays evenly.
