Description
Technical field
The invention belongs to tee pipe fitting preparation field, more particularly, to a kind of preparation of bamboo winding composite three-way pipe fitting
Method.
Background technology
Bamboo coiled composite tube is a kind of using bamboo wood as basis material, using thermosetting resin as adhesive, using winding process
Manufactured novel pressure product, the multiple tube have compressive resistance height, good rigidity, insulation, corrosion resistant, current excellent performance, it is light-weight,
The characteristics such as easy for installation, of low cost, service life length, can be widely applied to urban water supply and sewerage, water conservancy, field irrigation, oil
The fields such as sewage disposal, industrial circulating water.
Tee pipe fitting is common a kind of connecting pipe part in Pipe installing, and can connect more by threeway is not at together
The pipeline of one straight line.There are many moulding process of threeway at present, including direct Wrapping formed, hand pasting forming, extrusion forming or compacting
Shaping etc..It is very high to equipment and winding method requirement due to being directly wound in tee pipe fitting with bamboo fibre, it is difficult to realize.Hand is pasted
During shaping, due to manual operation, the poor dimensional precision and preparation efficiency of the three-way pipe prepared are low.Extruding or compression moulding one
As be suitable for the threeway of metal material and prepare, and bamboo winding composite tee pipe shaping can not be suitable for, and in extrusion molding mistake
Technological parameter is required in journey it is high, particularly with reduced tee, when hypertonia or it is too low when will cause cob webbing, lead
Cause is reprocessed or scrapped；Secondly in reducer tee shaping, the shape and size for deforming can just reach requirement several times, process are passed through
It is complicated；In addition inside/outside diameter size, circularity and Pingdu of side of the appearance profile of reducer tee including threeway etc. be directly and mould
The shape of core is related, and shape of threeway supervisor and branch pipe intermediate location etc. is obtained by molding die, and mold is proposed
High requirement.
To sum up, in order to realize the preparation of bamboo winding composite three-way pipe fitting, realize being reliably connected for bamboo coiled composite tube, need to grind
Study carefully and design a kind of preparation process suitable for bamboo winding composite three-way pipe fitting, to prepare meet intensity and size requirement three
Way pipe fitting.
The content of the invention
For the disadvantages described above or Improvement requirement of the prior art, the present invention provides a kind of bamboo winding composite three-way pipe fittings
Preparation method uses first winding threeway main pipe, and liner layer is then polished after line cutting, then compound through pasted technique shaping
Threeway has the advantages that easy to operate, efficient, low to mold requirement.
To achieve the above object, the present invention proposes a kind of preparation method of bamboo winding composite three-way pipe fitting, and feature exists
In this method comprises the following steps：
(1) winding prepares threeway main pipe, which is bamboo coiled composite tube, radially includes liner successively from the inside to the outside
Layer, structure sheaf and external protection coating, including main main pipe and branch main pipe；
(2) rule and cut in the main main pipe and branch main pipe prepared in winding；
(3) cut edge of the main main pipe and branch main pipe is polished into liner layer；
(4) branch main pipe with the liner layer polished in main main pipe is docked, liner layer is pasted at docking, solidify afterwards；
(5) after the liner layer pasted cures, fiber-reinforced composite materials structures layer is pasted on the liner layer pasted, it
Solidify afterwards carry out outside surface anticorrosion processing, prepare required tee pipe fitting after curing.
As it is further preferred that the length of the liner layer polished is preferably 10-20mm.
As it is further preferred that the liner layer that pasted at docking is specially：With infiltration epoxy resin adhesive
The liner layer at docking is made in the inner surface and the outer surface that fiberglass surfacing mat or glass fibre knitting felt are pasted at docking.
As it is further preferred that the fiber-reinforced composite materials structures layer is answered by high strength fiber peacekeeping Resin adhesive
It closes, the high strength fibre is glass fibre, the one or more in carbon fiber, basalt fibre, aramid fiber.
As it is further preferred that liner enhancing is first pasted using bamboo fiber felt and glue as raw material at the liner layer pasted
Layer, then pastes fiber-reinforced composite materials structures layer in the outside of liner enhancement layer.
In general, by the above technical scheme conceived by the present invention compared with prior art, mainly possess following
Technological merit：
1. the present invention using the main main pipe of threeway and branch main pipe is first wound respectively, then polish liner layer after line cutting,
Composite tee is molded through pasted technique again, breaches traditional preparation method of threeway, the preparation method is easy to operate, moulding process
Simply, requirement efficient, to mold is low, and winding main pipe parameter need to be only set according to winding process, reduces the difficulty of winding,
The threeway prepared has many advantages, such as that dimensional accuracy is high, strength character is good.
2. the present invention is using winding and pastes the means preparation threeway being combined, solving other shaping needs to deform several times
Can be only achieved shape and size requirement problem, paste process and molding die be more not required, reduce complicated die design and
Safeguard the manpower and materials expenditure of mold.
3. the tee pipe fitting to match with bamboo coiled composite tube prepared by the present invention, green in itself with bamboo coiled composite tube
The advantages of environmental protection, energy-saving low-carbon, except can be connected with bamboo coiled composite tube, can also be attached with rigid elements such as pumps,
The application range of threeway is further widened, and three-way pipe can reasonably select the connection with treating connecting pipe according to engineer application
Mode, such as flanged joint or bell and spigot connection, convenient for actual installation.
