Abstract
A kind of air mixed-flow high pressure nozzle.A main conical cavity and secondary conical cavity are equipped in its nozzle housing, one end of nozzle housing is connected with flow distribution plate, throughbore is evenly provided on flow distribution plate, the center of flow distribution plate is equipped with the rotary table of protrusion, rotary table front end is cone identical with the taper of main conical cavity, and an air chamber runs through the center of flow distribution plate.The uniformity of water jet is improved using two conical cavities and a cone, air chamber sprays pressure-air and drives uniform water flow to project at a high speed, and water flow can be accelerated more uniformly to be atomized；Structure is simple, but jet velocity is faster, and jet stream and atomization are also more evenly.
Description
Technical field
The present invention relates to a kind of nozzles, can be used to industry and meet accurate cutting requirement, it can also be used to the long-range spray of agricultural
Or it is used for fountain, the nozzle designed especially with air mixed flow technology.
Background technique
Industrially, in order to meet accurate cutting requirement, nozzle should have excellent jet characteristics and longer use the longevity
Life.(operating) water nozzle is the executive component of high-pressure water shot flow generating apparatus, and the effect of (operating) water nozzle is the receipts by nozzle bore cross section
Contracting gathers together the pressure energy of high pressure water, and is converted into kinetic energy, is finally sprayed outward in the form of high-pressure water jet to material
Carry out cutting processing.If High pressure water jet nozzle can be divided into circular cone convergent nozzle, circular cone band by the shape of cross section in nozzle
Cylindrical outlet section shape nozzle, streamline nozzle etc..Nozzle is equally used on a large scale in agriculturally water spraying atomization, especially remotely
Spraying nozzle, with the mechanization of agricultural, use is more and more wider.
Summary of the invention
Fast in order to manufacture a kind of jet velocity, the nozzle of water flow and atomization more evenly, it is mixed that the present invention provides a kind of air
Streaming high pressure nozzle, jet velocity is fast, and water flow and atomization are more evenly.
The technical scheme is that be equipped in the nozzle housing of air mixed-flow high pressure nozzle main conical cavity and
One end of secondary conical cavity, nozzle housing is connected with flow distribution plate, and throughbore, the center of flow distribution plate are evenly provided on flow distribution plate
Rotary table equipped with protrusion, rotary table front end is cone identical with the taper of main conical cavity, and this rotary table and cone are located at
In main conical cavity, an air chamber is located at the center of flow distribution plate, and air chamber runs through flow distribution plate, rotary table and cone.
A kind of prioritization scheme of above scheme are as follows: one end of the flow distribution plate is equipped with external screw thread.
Working principle of the present invention is that water enters in main conical cavity relatively uniformly by the through-hole of flow distribution plate, due to master
The pyramidal structure of conical cavity cone identical with its center taper so that water velocity faster and more water layer thickness more evenly
Ground sprays delivery nozzle, and secondary conical cavity improves the uniformity of water flow jet, positioned at the air chamber and pressure-air of nozzle center
It is connected, pressure-air drives uniform water flow to project at a high speed, and water flow can be accelerated more uniformly to be atomized.
The invention has the advantages that improving the uniformity of water jet, air chamber using two conical cavities and a cone
Spraying pressure-air drives uniform water flow to project at a high speed, and water flow can be accelerated more uniformly to be atomized；Structure is simple, but sprays
Faster, jet stream and atomization are also more evenly for speed.
Detailed description of the invention
Fig. 1 is structure principle chart of the invention.
1. nozzle housing in figure, 2. main conical cavities, 3. secondary conical cavities, 4. flow distribution plates, 5. throughbores, 6. rotary tables,
7. cone, 8. air chambers.
Specific embodiment
It is equipped with a main conical cavity 2 in Fig. 1, in the nozzle housing 1 of air mixed-flow high pressure nozzle and secondary taper is empty
One end of chamber 3, nozzle housing 1 is connected with flow distribution plate 4, and throughbore 5 is evenly provided on flow distribution plate 4, and the center of flow distribution plate 4 is set
There is a rotary table 6 of protrusion, 6 front end of rotary table is cone 7 identical with the taper of main conical cavity 2, and this rotary table 6 and cone 7
In main conical cavity 2, an air chamber 8 is located at the center of flow distribution plate 4, and air chamber 8 runs through flow distribution plate 4, rotary table 6 and circular cone
Body 7；One end of flow distribution plate 4 is equipped with external screw thread.
