[detailed description of the invention]
Below in conjunction with accompanying drawing, the utility model is described in further detail, and the structure of this device and principle are very clearly concerning the people of this specialty.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model is a kind of improved high-voltage pulse soap lye shower nozzle, and it is mainly made up of the large parts of front valve shell group, main valve body group and Cleaning bottle group three.Main valve body group is made up of main valve body 5, O shape circle, resilient key 7, jet valve body 8, gun joint, its operation principle is as follows: the High-Pressure Water flowed out from water pipe enters in jet valve body 8 by gun joint 10, water under high pressure from primary flow hand-hole 8c at a high speed by entering primary vacuum chamber 5c after elementary speedup hole 8b and elementary pressure-releasing hole 8a.Because High-Pressure Water forms vacuum after by primary vacuum chamber 5c, occur siphonage under the suction function that vacuum produces, cleaning solution can from Cleaning bottle 15 by sucking main valve body 5 throttle orifice 5d and together flowing to front valve shell 4 with current.Main valve body is connected with front valve shell elasticity, structure and assemble simple and reliable.The utility model also can be connected with hydraulic giant fast by a crossover sub, as with metal fast joint connecting mode and and common plastics hydraulic giant barral of a gun snap-fit.These two kinds of connected modes only need connect a crossover sub on the utility model.
Front valve shell group is made up of nozzle overcoat 1, foam generation net the 2, the one O shape circle 3 and front valve shell 4, and its operation principle is: be mixed with the High-Pressure Water of cleaning solution at a high speed by entering secondary vacuum chamber 4c after secondary speedup hole 5b and secondary pressure-releasing hole 5a.High-Pressure Water forms vacuum after by level time vacuum chamber 4c, siphonage is there is under the suction function that vacuum produces, air can suck in secondary vacuum chamber 4c from the perforate of nozzle overcoat 15, and the High-Pressure Water being at this moment mixed with cleaning solution and air rushes at foam generation net 2 by three grades of speedup hole 4b and three grade pressure-releasing hole 4a.Cleaning solution and air and High-Pressure Water are by being able to after foam generation net 2 full and uniformly mix also, part mixed liquor high speed impact adds in self-oscillation cavity 1c to 120 degree impingement area 1b back reflections, and with the mixed liquor just spray foam generation net 2 understand with after again impact on 120 degree of impingement area 1b.Mixed liquor can produce strong frostproof froth n effect under the oscillation action moved in circles like this, plays the best clean result of cleaning solution thus.The stream impulse ripple that High-Pressure Water defines in Induced Oscillation cavity 1c, the basis of enhanced foaming effect also can increase the range of current greatly.
The utility model has high pressure liquid suction function, cavitation jet function and pulse self-oscillation function.
Sub-high pressure imbibition operation principle and functional characteristics are: after forming certain vacuum in main valve cavity, cleaning solution just can suck in main valve body cavity under the effect of negative pressure from Cleaning bottle, and together spray in middle valve body with High-Pressure Water, the general principle of Here it is high pressure cleaning liquid function operation.Compare with comparatively low pressure soap lye shower nozzle, high pressure soap lye shower nozzle has following two significant advantages: cleaning effect significantly improves, and also reduces labour intensity in saving energy consumption simultaneously; Can effectively clean by object that is high or distant place, its effective working distance is 3 ~ 5 times that can reach low pressure cleaning solution shower nozzle.
Sub-high pressure wicking structure feature is: learn according to siphon principle, and after the vacuum in main valve body is more than 30kPa, the negative pressure that valve inner produces just can by cleaning solution in bottle and enter in its cavity.Because general power washer minimum pressure values generally only reaches 5000kPa, according to this situation, the structure of the utility model to metallic nozzle re-starts optimal design, guarantees that High-Pressure Water can maintain rational speed to reach required vacuum at nozzle exit.After repeatedly calculating the nozzle optimized and verify, it is 4mm that the nozzle of setting imports and exports aperture, and the aperture of stage casing speedup aperture is 1.2mm+/-0.2mm.Produce best vacuum effectiveness to guarantee, prevent water under high pressure from producing refluence phenomenon, the distance of nozzle exit end and cleaning solution throttle orifice center line designs within 1.0mm simultaneously.Certain loss can be produced because hydraulic system is formed in vacuum process in valve chamber, add and there is the damping hole that controls cleaning solution flow between main valve chamber and cleaning solution pipe, therefore vacuum must need be brought up to about 70kPa from calculated value 30kPa.Consider that water under high pressure that operator also needs after using cleaning solution function is to dispose the cleaning solution of target surface, the design also add cleaning solution handoff functionality.When cleaning solution transfer valve is set in " open-minded " shelves, now damping hole communicates with main valve body through hole, now can produce certain vacuum in system to realize self-priming cleaning solution function; When cleaning solution transfer valve is set in " closing " shelves, now large passage communicates with main valve body through hole, directly communicates, cannot produce enough vacuum to realize self-priming cleaning solution function, only have the single function that sprays water with high pressure in now in system with air.Operator only need regulate cleaning solution transfer valve just can achieve the above object simply.Here, large passage, damping hole and main valve body through-hole aperture get 4mm:1mm:4mm respectively.
The theory calculate of sub-high pressure liquid suction function: according to Bernoulli equation (z

e=z
2* g+u
2 2/ 2+p

Cavitation jet principle and functional characteristics: after highly pressurised liquid carries out middle valve chamber at a high speed from secondary jets hole, high-speed jet is along shrinkage hole, and during speedup hole and diffusion hole flow out, valve body enters front valve shell.In this jet process, the VELOCITY DISTRIBUTION of Callous pad inside reaches maximum in front end, speedup hole, with the medium of surrounding, strong shear action occurs, produce the generation that obvious negative pressure is conducive to cavitation bubble in diffuser.Outside air sucks in cavity from four passages under the effect of this negative pressure, and sprays from diffusion hole with high-velocity flow one.The design is the structure optimization by diagonal form nozzle, make use of jet dexterously and can produce a large amount of cavitation bubble phenomenon by Callous pad, water under high pressure and the abundant of cleaning solution is fused, strengthens its compressive stroke strength and reach the object improving cleaning effect.The basis that the utility model make use of the theory of cavitation jet has carried out improving and optimizing to the structural design of Cavitation jet nozzle, nozzle after optimization can not only produce enough vacuum and suck in cavity by extraneous air, and highly pressurised liquid fully can be mixed under cavitation with air, after cavitation, mixing material can produce best cleaning performance.The aperture of the shrinkage hole of Cavitation jet nozzle gets generally acknowledged 13.5 °, and its length gets 25 to 30mm; Nozzle diffusing opening aperture is taken as 30 °, and its length gets 10mm (+/-2.0mm); 2.8mm (+/-0.2mm) is chosen in the aperture of stage casing speedup aperture, and its length gets 3mm (+/-1.0mm).Produce best vacuum effectiveness to guarantee, prevent water under high pressure from producing refluence phenomenon, the distance of secondary jets hole exits end face and airport center line gets 3mm+/-0.5mm simultaneously.
Self-excited pulse oscillation principle and functional characteristics are: after cavitation jet carries out front valve chamber, and high-speed jet directly sprays to impulse hunting ring.Due to the project organization that impulse hunting ring is special, part streams and impulse hunting ring front end face collide and produce pressure oscillation ripple in impact zone, and this ripple is oppositely upstream propagated with the velocity of sound, brings out vorticity fluctuation.The continuous reciprocation cycle of this process will form strong self-excited oscillation pulse jet.This jet has larger transformation characteristic and very strong cavitation, consequently increases plasma jet range, improves energy constant and cleaning performance.The design's structure optimization that has been the carrying out to self-excited nozzle, make use of self-excited oscillation pulse jet to reach the object improving clean range and strengthening cleaning effect dexterously.Can know from experimental result and find out that its battle range can improve 20%, instantaneous impact improves 1.5 times.
The operating pressure of self-excited nozzle is generally 200psi, and its working flow is 1.0 ~ 1.5GPM.Experimentally test is learnt, speed self-excitation effect when 40 ~ 50m/s of nozzle entrance is better.Top nozzle diameter d can be calculated thus
1(4Q/ (pi*v)=2.8 ~ 3.4mm can rounding be d to=sq
1=3.0mm.Lower nozzle d
2with top nozzle d
1the optimization range of ratio is: d
2/ d
1=2.0, therefore lower nozzle diameter elects 6mm as.Because its length is less to self-excited pulse influential effect, be taken as 15mm according to actual conditions.Testing surface can produce the self-excited oscillation cavity footpath d of better self-excitation effect
3size range is: d
3/ d
2=2.0, therefore the self-excited oscillation cavity diameter elects 12mm as.The optimization range of the self-excited oscillation cavity chamber length is: c/d
3=0.7, therefore the long c of the self-excited oscillation cavity elects 8.4mm as.According to result of the test, impact walls cone angle can be defined as 120 °.
In the practice process of self-excited oscillation pulsed water jet, self-excited pulse function group is constituted by top nozzle, lower nozzle, the self-excited oscillation cavity and collision wall, the above-mentioned principle of its structural principle is consistent, and self-excited oscillation pulse phenomenon is successfully created in real work, namely after water under high pressure is by this valve group, just can produce self-excited oscillation pulse jet.Such self-excited oscillation pulsed water jet obtains and successfully applies in the utility model.Because the design's front valve shell have employed plastic material, therefore self-excited oscillation pulse structure cannot be realized in Shooting Technique.The utility model increases a metal insert in front valve shell, and one is jointly realize this function with associated components, and two is working lives that the application of metal material can increase product widely.In order to increase mixing of cleaning solution and water under high pressure, increase cleaning effect, the design adds a foam producer in front valve shell, when mixing material can produce a large amount of bubble by foam producer, is conducive to cleaning solution and strengthens its catalytic reaction, thus strengthens cleaning performance.
