Abstract
The utility model relates to a nozzle of improving flow distribution. The utility model is mainly characterized in that an outlet cross section of a nozzle flow path is an isosceles trapezoid and the inlet cross section of the nozzle flow path is circular. Gradual smooth transition is provided from the circular cross section of the inlet flow path to the isosceles trapezoid cross section of the outlet flow path. The utility model enables the pressure of the liquid in the same direction to be distributed from top to bottom and from high position to low position and thus the uniform distribution of the liquid can be realized. The utility model has the advantages of simple structure, convenient manufacture, scientific design and energy saving. The utility model is suitable for industrial and agricultural use.
Description
The utility model relates to nozzle, especially a kind of nozzle that improves flow distribution.
Existing nozzle flow channel is mainly circle, its jet comparison rule, and flow-rate ratio is more concentrated, to agricultural water nozzle, causes pouring inhomogeneous; To atomizer, cause burning quality not high.
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of simple in structure, design science and can effectively improve the nozzle of flow distribution.
The purpose of this utility model is achieved in that
The nozzle flow channel outlet is an isosceles trapezoid, and nozzle flow channel import cross section is circular, and isosceles trapezoid cross section from the circular cross-section of inlet channel to outlet flow is a rounding off gradually.
Advantage of the present utility model and good effect are:
Because the isosceles trapezoid from the circle of runner import to runner exit is transition gradually, cause liquid to raise at the convergent contour flowpath pressure on isosceles trapezoid top, liquid sprays far away, divergent contour runner exit pressure in isosceles trapezoid bottom reduces, liquid sprays nearer, therefore cause liquid to upward pressure and distribute to low by height from top to bottom, thereby can realize the even distribution of liquid same side.The utility model is simple in structure, and is easy to make, and design science is saved the energy, is applicable to the industrial or agricultural use.
Description of drawings:
Fig. 1 is a nozzle longitdinal cross-section diagram of the present utility model;
Fig. 2 is Figure 1A A ' view in transverse section;
Fig. 3 is Figure 1B B ' view in transverse section;
Fig. 4 is Fig. 1 CC ' view in transverse section.
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
Nozzle profile is generally circle, is made of outer wall 1 and runner 2.The nozzle flow channel outlet is an isosceles trapezoid, and nozzle flow channel import cross section is circular, and isosceles trapezoid cross section from the circular cross-section of inlet channel to outlet flow is a rounding off gradually.Liquid raises at the convergent contour flowpath pressure of isosceles trapezoid top, liquid sprays far away, divergent contour runner exit pressure in isosceles trapezoid bottom reduces, liquid sprays nearer, therefore cause liquid to upward pressure and distribute to low by height from top to bottom, thereby can realize the even distribution of liquid same side.
