Description

A kind of high performance corrosion-proof elbow
Technical field
The utility model relates to a kind of elbow, specifically a kind of high performance corrosion-proof elbow.
Background technique
Phosphorous chemical industry, chemical fertilizer, petroleum and petrochemical industry, smelting iron and steel etc. conveying corrosive fluid medium occasion, metal bends because It being worn to will receive corrosion and general plastic lining elbow, being unable to high temperature resistant, high negative pressure, it is clear that it is not available, therefore This kind of occasion, it usually needs wear resistant corrosion resistant high performance corrosion-proof elbow is used, and domestic existing wear resistant corrosion resistant is curved at present 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 Type processability has more better than polytetrafluoroethylene PTFE, and improved high performance corrosion-proof elbow is on steel shell inner wall It is welded with net metal silk, uses rough processing on steel flanges sealing surface, steel inner wall derusts coarse sand, improved high property Can corrosion-resistant elbow, on the inner wall for being pasted on steel shell 1 of backing layer fluoroplastics 4 tightly and encase wire mesh 3, and be dissolved in One, in this way when generating high temperature, authentic dummy status in system, high performance corrosion-proof elbow inner liner layer fluoroplastics 4 will not be risen Phenomena such as layer, bulge, also overcoming to expand with heat and contract with cold influences backing layer fluoroplastics 4, and sealing surface will not produce fracture phenomenon;Make to produce Product service life increases by 2 times, is the call of national energy-saving, reduces user's purchase cost about 40%~50%.
The preferred embodiment of the patent is described in detail above, but this patent is not limited to above-mentioned embodiment party Formula within the knowledge of one of ordinary skill in the art can also be under the premise of not departing from this patent objective It makes a variety of changes.
