Description
Technical field
The present invention relates to pipes to clean field, is a kind of pipe cleaning shunt head and its cleaning method.
Background technology
Small-bore precision stainless steel pipe can all carry out bright solution treatment after cold rolling, and bright before processing is had to pipe
The remaining ROLLING OIL of wall surface is removed totally, if tube wall grease is not removed totally, steel pipe quality can be directly affected, when serious
It can cause residual CI- corrosion steel pipes（Because ROLLING OIL chlorination-containing olefin ingredient）.Generally using the cleaning of ultrasonic wave slot type or pickling
（Nitric acid+hydrofluoric acid）Immersion treatment, and ultrasonic wave and pickling can only have pipe outer wall cleaning action, for elongated inside pipe wall base
This is invalid, therefore to be subsequently also further processed for inside pipe wall.Existing inside pipe wall cleaning way generally uses and manually beats sponge
Ball, felt or calico etc. wipe rubbing action by sponge ball and remove grease.Because cold-rolled lubricating oil passes through high temperature in the operation of rolling
Become very sticky it is thick, strength roll after the microcosmic gap of tube wall can be embedded in more superfines and one layer of complete oil film,
Therefore sponge or calico is needed to pick the volatile solvents such as acetone and further clear up.Every pipe is different with caliber according to pipe range, leads to
Often need beat sponge ball quantity it is more, but cannot be guaranteed inner wall cleannes, therefore before heat treatment or processing after it is necessary
Pickling is recycled to eliminate corrosion of the residue to tube wall.For this purpose, the sector be badly in need of one kind can high cleaning rate, low cost, from
Dynamicization, the cleaning technique of environmental protection, can substitute artificial and high pollution acid cleaning process completely.
The content of the invention
To overcome above-mentioned deficiency, the purpose of the present invention is provide a kind of pipe cleaning shunt head and its cleaning side to this field
Method, solving it, existing inside pipe wall cleaning cleaning efficiency is not high, and cost is higher, automation, the technical issues of feature of environmental protection is not good enough.Its
Purpose is achieved by the following technical solution.
A kind of pipe cleans shunt head, which cleans suitable for inside pipe wall, shunt head one end connection flexible connection line, point
It flows and jet stream gap is formed between head and pipe fitting inner wall to be cleaned, which is defined to pass through the jet stream gap when high-pressure fluid
When form annular cavitation jet.Its structural feature is that the shunt head front end is equipped with the threading for connecting the flexible connection line
Piece occurs for hole, the vacuole that shunt head middle part is equipped with spaced two panels annular, is respectively that preceding vacuole generation piece and rear vacuole are sent out
Raw cook, shunt head front end to preceding vacuole occur piece and form the preceding gradual change head that outer diameter becomes larger, and piece and rear vacuole occur for preceding vacuole
The vacuole generation cavity of annular indent is formed between generation piece, the anchor ring of vacuole generation cavity and rear vacuole occur to form outer diameter between piece
The rear gradual change head become larger, the preceding vacuole occurs between piece and pipe fitting inner wall to be cleaned and rear vacuole occurs piece and treats clear
It washes between pipe fitting inner wall and is respectively formed the jet stream gap.
Cavitation jet refers to that high-pressure fluid is delivered to shunt head by pipe fitting to be cleaned, and the shunt head speed of travel is less than fluid
During speed, shunt head front end fluid forms high-pressure fluid, and the tube wall for by shunt head fluid being made to be close to pipe fitting to be cleaned compresses, wink
Between into shunt head rear end low-pressure area formed pressure drop.It is not only molten when fluid local pressure is less than saturated vapor pressure at this
Air in water（Usually 2%）It can escape, and water starts to gasify, and forms many in a fluid and is made of air and fluid
Vacuole（Hole, cavitation bubble）, fluid carries when vacuole high-frequency hits tube wall and forms sound wave, when frequency is higher than 20000Hz
Then form ultrasonic wave, ultrasonic wave generates vacuole and constantly hits tube wall again, whens these bubble collapses generate instantaneous localized hyperthermia,
High pressure, and form strong shock wave and speed is up to the microjet of more than 100m/s, so as to fulfill cleansing pipe fitting inner wall is treated
Cleaning.Above-mentioned shunt head design can not only generate secondary cavitation jet, and by setting vacuole generation cavity, can be conducive to
The generation of pipe fitting inner wall vacuole to be cleaned, greatly improves inside pipe wall cleaning efficiency and cleaning effect.
In above-mentioned pipe cleaning shunt head, the outer diameter that piece occurs for the preceding vacuole is more than the outer diameter ruler that piece occurs for rear vacuole
It is very little, and the edge circumferential surface of piece occurs for vacuole for arc surface.In above-mentioned pipe cleaning shunt head, the housing width of the vacuole generation cavity
Less than 1.5 times of the shunt head maximum outside diameter size.
By said structure, be conducive to the generation of vacuole, improve the effect of cavitation jet cleaning.
In above-mentioned pipe cleaning shunt head, the threading hole is the parallel hole through shunt head front and rear ends.
In above-mentioned pipe cleaning shunt head, the threading hole is T-shaped hole.
The threading hole design of above-mentioned shunt head facilitates flexible connection line threading binding operation and is pulled after improving binding
The stability and reliability of shunt head work.
In above-mentioned pipe cleaning shunt head, the material of the shunt head is hard nylon, polyformaldehyde, polyurethane, polyvinyl chloride, super
High molecular polythene it is therein any one.With this configuration, the wearability of shunt head in itself is ensured, while easy damaged is not treated again
Cleansing pipe fitting inner wall.
In above-mentioned pipe cleaning shunt head, the flexible connection line works out fiber line for multiply.With this configuration, improve flexible
The tensile strength of connecting line, and the winding that itself knots is not easy, improve the reliability for pulling shunt head work.
The pipe cleaning shunt head cleaning method be：The shunt head is stretched by one end of pipe fitting to be cleaned, and to treating
The cleansing pipe fitting end is passed through high-pressure fluid, and the flexible connection line pulls shunt head same compared with high-pressure fluid along pipe fitting to be cleaned
To or counter motion, and when shunt head and high-pressure fluid move in the same direction, shunt head gait of march is less than the flow velocity of high-pressure fluid；
The high-pressure fluid by vacuole before shunt head occur piece, after vacuole twice jet stream between piece and pipe fitting inner wall to be cleaned occurs
Gap forms secondary annular cavitation jet, completes annular cavitation jet by treating whole section of cleansing pipe fitting inner wall, realization is treated clear
Wash the cleaning of pipe fitting inner wall.
The high-pressure fluid is clear water, degreaser, pickle, and viscosity, close to water, high-pressure fluid temperature is 10-45 DEG C.
It is set by the high-pressure fluid, the generation of vacuole can be improved, improve the effect of cavitation jet.It is described in above-mentioned cleaning method
Shunt head is made past under the flexible connection line pulling function and under high-pressure fluid impetus along pipe fitting inner wall to be cleaned
Multiple movement, further improves inside pipe wall cleaning performance.
The advantage of the invention is that：Overall structure is relatively simple, and making production cost is relatively low and easy for operation, right
Relatively low in the pressure requirements of high-pressure fluid conveying, cleaning efficiency is high, and effect is good, is particularly suitable for tube wall dirt adhesion-tight, pipe
Not clean small-bore of wall（Caliber is less than 25mm）Inside pipe wall cleaning, be suitable for heavy industrialization cleaning.
