Description
Technical field
The invention belongs to cleaning equipment technical field, and in particular to a kind of pressure linear regulation combination nozzle and high-pressure wash
Equipment.
Background technology
High-pressure cleaning device is a kind of using water or the mixed liquor added with cleaning agent is cleansing medium, utilizes high pressure water flow real
The equipment of existing body surface cleaning, it has mainly formed spray gun unit and motor pump unit, and spray gun unit is responsible for according to actual need
Current of different shapes are formed, and motor pump unit is responsible for water being delivered in spray gun unit from municipal water pipe.
For nozzles/spray heads as the executive component in high pressure water cleaning complete set of equipments, its principle is to utilize nozzles/spray heads endoporus
The change of area makes high pressure water gather together, and changes into kinetic energy and sprayed again in the form of high-speed jet, so as to be carried out to material
The purpose of smashing, peel off, washing away, reaches due cleaning performance.But how to realize high pressure nozzle and low-pressure nozzle
Combination, and accomplish it is simple in structure, reliable, easy to manufacture, easy to assembly, and high-low pressure is easy to adjust, performance is stable, peace
Entirely, it is good etc. to clean cleaning effect, is always the problem of practitioner perplexs.

Positive stop 702 and backstop 703, form card slot 704 between positive stop 702 and backstop 703, pushing block 603 is located in card slot 704.
As it can be seen in figures 5 and 6, the outer wall of slide-valve 6 is cylindrical surface, there is the second annular groove of ring around it on cylindrical surface
602, the second sealing ring 8 is set with the second annular groove 602 so that slide-valve 6 is formed with head capsule 1 is slidingly sealed.High pressure nozzle 3
The openend backward of inner cylinder face 303 have the ring packing side 304 of an amplification, the external cylindrical surface 606 of slide-valve 6 it is rear square
Cheng Youyi male cone (strobilus masculinus)s 607, ring packing side 304 can be close to male cone (strobilus masculinus) 607 realize it is secondary between slide-valve 6 and high pressure nozzle 3
Sealing.
As shown in Fig. 9,10 and 12, high pressure nozzle 3 can be pushed into the cavity of head capsule 1 from the rear end of head capsule 1, high pressure nozzle 3
With at least one first periphery 306 and at least one first positioning plane 305 adjacent with the first periphery, head capsule 1
With at least one with 306 matched second periphery 103 of the first periphery and at least one adjacent with the second periphery 103
Connect and with first positioning plane 305 be engaged with prevent high pressure nozzle 3 with respect to head capsule 1 rotate second position plane 102.Head capsule
1 with terminal surface 104 is used for, and high pressure nozzle 3 has step surface 309, high pressure spray when terminal surface 104 is in contact with step surface 309
The depth that mouth 3 is inserted into head capsule 1 is limited.The front end of high pressure nozzle 3, which has, radially extends the first V-groove mouth 308 to be formed, the
One V-groove mouth 308 be connected with center spray road to be formed ellipse water outlet 301 so that spray water formed 10 ° to 75 ° it
Between sector.
As shown in Fig. 4,13,14 and 15, as a kind of typical low pressure delivery mode, pressure linear regulation combination nozzle is also
Including low-pressure nozzle 2 and spring 4, low-pressure nozzle 2 is slidably disposed in the cavity of head capsule 1 and is slided with the formation of head capsule 1 close
Envelope, low-pressure nozzle 2 are located at the front of high pressure nozzle 3, and spring 4 is located in the cavity of head capsule 1 and abuts low-pressure nozzle 2 and head capsule 1,
Low-pressure nozzle 2 can contact formation sealing with high pressure nozzle 3；Low-pressure nozzle 2 has a main water outlet 201 and is arranged at its side
At least one auxiliary water outlet 202, auxiliary water outlet 202 is connected with bypass path 101.The rear end of low-pressure nozzle 2 has a ring
Shape sealing strip 205, the outer wall of high pressure nozzle 3 are also formed with an inner cone 307, and ring packing side 304 can be close to inner cone 307
Realize sealing.The front end of low-pressure nozzle 2, which has, radially extends the 3rd V-groove mouth 203 to be formed, and the 3rd V-groove mouth 203 makes master
Water outlet 201 is oval towards open front so that the water sprayed forms the sector between 10 ° to 75 °.Auxiliary water outlet 202 is located at
The side of plane, auxiliary water outlet 202 intersect with the water outlet direction of main water outlet 201 where the fan-shaped water that main water outlet 201 sprays
Converge.The water outlet direction place of intersecting of auxiliary water outlet 202 and main water outlet 201 is located at the inside of head capsule 1.
The low-pressure nozzle 2 set by activity so that in the initial stage that high pressure is changed to low pressure, pass through bypass path
101 flow to current at low-pressure nozzle 2 and hydraulic pressure is smaller, and water, which flows through auxiliary water outlet 202 and forms shallow bid current, at this time outwards sprays
Go out, this strand of current finally rush at front so as to avoid it from directly dropping onto ground by the higher current of the pressure that water outlet 301 sprays
Face and the normal use for influencing equipment.When dredging flow groove 601 gradually open flow through bypass path 101 current increase when, its by
Gradually push low-pressure nozzle 2 to front so that 2 rear end of low-pressure nozzle is connected with bypass path 101, current can directly lead at this time
The main water outlet 201 for crossing low-pressure nozzle 2 sprays.
Embodiment two
As shown in figure 17, it is with one difference of embodiment, in the present embodiment, as another typical linear regulation knot
Structure, dredging flow groove 601 are formed along helix extension, and the centerline axis parallel of helix is in the central axis of external cylindrical surface 606.Except reality
Apply outside example one and the present embodiment, dredging flow groove 601 can also use other structures, such as it is slanting, but be in order at be manufactured into this and
