Abstract
The invention relates to a spray nozzle, in particular to an atomized water spray nozzle. In the prior art, the atomized water spray nozzle premixes under-pressure air and water first and then performs high-speed spraying to form atomization, an intermittent spraying phenomenon exists by adopting the spray nozzle structure form, and working is instable. The invention provides an atomizing spray nozzle structure which does not premix water and air in advance. High-pressure air is firstly sprayed out through a Laval spray tube in an accelerated mode and enters an atomizing channel, water in an outer annular cavity of the atomizing channel enters the atomizing channel through water-permeating holes formed in an inner wall, and high-speed airflows crush, atomize and spray out the water entering the atomizing channel. Due to the fact that premixing is not needed, the intermittent spraying defect of a spray pipe caused by the prior art is overcome, and the working process is stable.
Description
Technical field
The present invention relates to nozzle, and in particular to a kind of aerosol (operating) water nozzle.
Background technology
Aerial fog nozzle has been widely used in cooling control, the spray of such as heavy casting and forging heat treatment process of hot environment
The field such as mist quenching and dedusting, humidification, plays regulation intensity of cooling, adds moisture etc. to refer to by adjusting gas-water ratio in proportion
Mark, and become very convenient reliable method.The operation principle of traditional aerial fog nozzle is typically that two kinds of fluid media (medium)s are pre-
First first mix a larger mixing interior, then sprayed by definite shape with mixed pressure.
After determining according to the nozzle specifications and models of aforesaid way design, there is one more stable mixing is adapted with it
Ratio and more moderate flow and inlet pressure ratio, its mixed comprehensive pressure is often depending on a kind of larger Jie of flow
Matter, and for the less medium of flow, its meter pressure should deduct blend pressure equal to its inlet pressure, therefore, want to keep
Certain flow mixing must have the pressure bigger than big flow to meet the condition of its normal work.It is raw for actual big industry
In product, particularly in the engineering of multiinjector integration of operation, it is impossible to which each nozzle sets a pipeline, generally using certain amount
Nozzle be connected in parallel on an arm for one group, in the case where the control of main pipeline flow is certain, a pipe pressure will be with nozzle
The increase of number its branch's pressure is weakened, for each nozzle, when low discharge medium entrance pressure is less than mixing pressure
Barrier will be produced during power, it is impossible to flow out, the situation of nozzle cutout now occur；Subsequently as the continuous inflow of upstream fluid is responsible for
Road pressure to nozzle is transmitted, and nozzle inlet pressure is increased, and barrier is broken again, therefore causes fluid to be in batch-mixed
With ejection, main line flow occurrence law fluctuation, it is impossible to normal work.
Therefore it is this to be first pre-mixed air water with pressure, then spray at a high speed and form the nozzle arrangements form of atomizing effect and have
Huge limitation.
The content of the invention：
It is an object of the invention to provide it is a kind of not by the gentle atomizing nozzle structure being pre-mixed of water, change low in prior art
Caused nozzle cutout phenomenon when flow medium entrance pressure is less than blend pressure, it is ensured that the job stability of nozzle.
In order to realize foregoing invention purpose, the technical scheme is that：A kind of aerosol (operating) water nozzle, includes base, spray boom, spray
Mouth cap and Laval nozzle, cap of spraying nozzle is screwed on the ring screw platform of the end of spray boom, and the root of spray boom is connected to base
On；The double-layer sleeve structure that spray boom is made up of outer wall and inwall, is a toroidal cavity between outer wall and inwall；Open on base
There is inlet opening to lead to toroidal cavity, the center of spray boom is the nebulization channel surrounded by inwall；Permeable hole is provided with inwall, annular is empty
It is connected by permeable hole between chamber and nebulization channel；Air admission hole is provided with base, air admission hole is connected with nebulization channel, and
Air admission hole is with nebulization channel on the same axis；Laval nozzle is arranged in air admission hole.
Preferably, 2 locating pieces are additionally provided with base.
Preferably, the corner of base is provided with fastening screw.
Preferably, sealing shroud is cased with Laval nozzle, the position of sealing shroud correspondence inlet opening is accordingly provided with permeable hole.
Preferably, inlet opening is provided with multiple, and inlet opening is equally spaced around air admission hole.
Preferably, permeable hole is uniformly distributed on inwall.
The present invention has compared to existing technology advantages below：
（1）Gases at high pressure accelerate to spray by Laval nozzle, and high-speed gas enter nebulization channel, and the water in toroidal cavity passes through
Permeable hole on inwall enters nebulization channel, and the air-flow of high speed is by into the broken atomization of the water attack of nebulization channel and then ejection.Due to
Need not be pre-mixed, it is to avoid the defect of the intermittent spraying of jet pipe caused by prior art, the course of work is stable.
（2）Nebulization channel is communicated with atmospheric environment, and according to Bernoulli effect, gas is interior when nebulization channel speed is accelerated
The pressure on interface that wall is contacted with gas can reduce to form pressure reduction, need not now apply extra pressure, in toroidal cavity
Water will enter nebulization channel.In relative to prior art, by way of water and gas are pressed into nozzle by pressurization, the present invention is only
Gas-pressurized is needed, without the need for additional hydraulic equipment.
