Head cannot get requirement for phosphorous chemical industry, chemical fertilizer, petroleum and petrochemical industry, smelting iron and steel due to its structure and technology.
The shortcomings that existing corrosion-resistant elbow:
High-low temperature resistant, high negative pressure are unable to when 1. existing corrosion-resistant elbow is because using, it is necessary to be increased inside elbow anti-negative
Pressing ring is adopted between backing layer and steel shell and is fastened with glue, and causes production manufacture is difficult to improve cost, product is caused to be tieed up
Repair inconvenience.
2. backing layer understands aliquation, bulge to existing corrosion-resistant elbow at high temperature in use.
3. flange sealing surface can produce fracture when existing corrosion-resistant elbow expands with heat and contract with cold in use.
Utility model content
The purpose of this utility model is to provide a kind of high performance corrosion-proof elbows, to solve to propose in above-mentioned background technique
The problem of.
To achieve the above object, the utility model provides the following technical solutions:
A kind of high performance corrosion-proof elbow, including elbow body, the elbow body include steel shell, connecting flange,
Steel shell is arranged in wire mesh and backing layer fluoroplastics, the elbow body, and connecting flange, steel is arranged in the end of steel shell
Wire mesh is arranged in the inside of shell processed, and wire mesh is welded in steel shell inner wall, and the inside of the elbow body is equipped with lining
Inner layer fluoroplastics.
As a further solution of the present invention: the steel shell is die casting and molding structure.
As a further solution of the present invention: the steel shell and connecting flange use casting integrated formula structure,
No-welding-seam between connecting flange and steel shell.
As a further solution of the present invention: the wire mesh is prismatic reticular structure.
The backing layer fluoroplastics are Meltability polytetrafluorethyletubular, lining as a further solution of the present invention,
Layer fluoroplastics are coated on overcurrent position and flange sealing surface in elbow body.
Compared with prior art, the utility model has the beneficial effects that
1. improved high performance corrosion-proof elbow passes through structural improvement and optimization, steel shell is adopted with connecting flange
With casting integrated formula structure, no-welding-seam phenomenon between flange and elbow.
2. improved high performance corrosion-proof elbow is to be welded with net metal silk on steel shell inner wall, steel method
Rough processing is used on blue sealing surface, steel inner wall derusts coarse sand.
3. improved high performance corrosion-proof elbow, backing layer fluoroplastics being pasted on steel shell inner wall and encasing tightly
Wire mesh, and it is dissolved in one, in this way when generating high temperature, authentic dummy status in system, high performance corrosion-proof elbow inside liner
Layer fluoroplastics will not aliquation, phenomena such as bulge, also overcoming to expand with heat and contract with cold influences backing layer fluoroplastics, and sealing surface will not generate
Phenomenon of rupture increases product service life by 2 times, reduces user's purchase cost about 40%~50%.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of high performance corrosion-proof elbow.
In figure: 1- steel shell, 2- connecting flange, 3- wire mesh, 4- backing layer fluoroplastics.
Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
Referring to Fig. 1, a kind of high performance corrosion-proof elbow, including elbow body, the elbow body include steel shell
1, steel shell 1, the steel shell 1 is arranged in connecting flange 2, wire mesh 3 and backing layer fluoroplastics 4, the elbow body
It is die casting and molding structure, connecting flange 2 is arranged in the end of steel shell 1, and the steel shell 1 is used with connecting flange 2
Wire mesh 3, institute is arranged in the inside of casting integrated formula structure, no-welding-seam between connecting flange 2 and steel shell 1, steel shell 1
Stating wire mesh 3 is prismatic reticular structure, and is welded in 1 inner wall of steel shell, and the inside of the elbow body is equipped with backing layer
Fluoroplastics 4, the backing layer fluoroplastics 4 are Meltability polytetrafluorethyletubular, and backing layer fluoroplastics 4 are coated on overcurrent in elbow body
Position and flange sealing surface, the 4 backing layer fluoroplastics partial vacuum rotational molding technology of backing layer fluoroplastics, elbow body it is interior
Hard-pressed bale is overlying in elbow body on overcurrent position and flange sealing surface under the action of wall wire mesh 3, ensure that elbow body exists
It is worked normally under high/low temperature, vacuum, using partial vacuum rotational molding technology, ensure that the thickness uniformity and densification of backing layer
Property；The effect of wire mesh 3 is coated on inner liner layer tightly on 1 inner wall of steel shell, uses under high/low temperature and vacuum
There is not aliquation, bulge is very suitable for using on the etch-proof working condition of Large diameter, to provide a kind of leakproofness
Can it is good, economical and practical, corrosion resistance is high, the high performance corrosion-proof elbow of resistance to high vacuum, long service life etc..
High-low temperature resistant, high negative pressure are unable to when existing corrosion-resistant elbow is because using, it is necessary to increase anti-negative pressure inside elbow
Circle, adopts between backing layer and steel shell and fastens with glue, and causes production manufacture is difficult to improve cost, leads to product repairing
Inconvenience, backing layer understands aliquation, bulge, flange sealing surface meeting when expanding with heat and contract with cold in use at high temperature in use
It produces fracture.
The improved high performance corrosion-proof elbow of the utility model passes through structural improvement and optimization, steel shell and company
Acting flange uses casting integrated formula structure, no-welding-seam phenomenon between flange and elbow, and backing layer fluoroplastics are moulded using backing layer fluorine
Expect 4 partial vacuum rotational molding technologies, be Meltability polytetrafluorethyletubular, properties as polytetrafluoroethylene PTFE, but at
