The technology status and disadvantage of existing corrosion-resistant elbow
It is unable to high-low temperature resistant, high negative pressure when 1. existing corrosion-resistant elbow is because using, circular arc degree is larger, leads to production
Manufacture is difficult to improve cost, causes product repairing inconvenient.
2. backing layer meeting aliquation, the bulge under high/low temperature, high vacuum in use of existing corrosion-resistant elbow.
Flange sealing surface when 3. existing corrosion-resistant elbow expands with heat and contract with cold in use, can be generated at camber minimum it is disconnected
It splits.
Utility model content
The purpose of this utility model is to provide a kind of continued-mounted high performance corrosion-proof elbows, to solve above-mentioned background technique
The problem of middle proposition.
To achieve the above object, the utility model provides the following technical solutions:
A kind of continued-mounted high performance corrosion-proof elbow, including elbow body, the elbow body include steel shell, connection
Steel shell is arranged in flange, adjusting pad and backing layer fluoroplastics, the elbow body, and connection method is arranged in the end of steel shell
Orchid, the inside of the elbow body are equipped with backing layer fluoroplastics, and adjusting pad, the adjusting pad peace are provided in the elbow body
Loaded on the position between backing layer fluoroplastics flange sealing surface and steel flanges sealing.
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 backing layer fluoroplastics use polytetrafluoroethylene PTFE plate,
It is coated in elbow on the sealing surface of overcurrent position and connecting flange.
Backing layer fluoroplastics are segmentation structures as a further solution of the present invention,.
Compared with prior art, the utility model has the beneficial effects that
1. improved continued-mounted high performance corrosion-proof elbow pass through structural improvement and optimization, steel shell with connect
Flange uses casting integrated formula structure, no-welding-seam phenomenon between flange and elbow, and backing layer fluoroplastics use plate Pian tight liner compound
Technique.
2. improved continued-mounted high performance corrosion-proof elbow is used on steel flanges sealing surface using segmentation structure
Rough processing, steel inner wall derust coarse sand.
3. improved continued-mounted high performance corrosion-proof elbow, Pian tight liner is compound to paste work using novel high-low temperature resistant glue
Skill, backing layer fluoroplastics plate do not need progress sodium and go fluorine except reason, and backing layer fluoroplastics flange sealing surface and steel flanges are close
Increase by one layer of high-low temperature resistant adjusting pad between envelope, adjusting pad increases the influence that leakproofness and system are expanded with heat and contract with cold, while to pipe
Corner forms circular arc together between wall and flange, prevents backing layer fluoroplastics sealing surface flange from fractureing when forming.
4. improved continued-mounted high performance corrosion-proof elbow, warm by system using major radius orthodrome is eliminated after segmentation
The influence of swollen shrinkage connects dress formula high performance corrosion-proof elbow lining in this way when generating high/low temperature, high vacuum state in system
Layer fluoroplastics will not aliquation, phenomena such as bulge, sealing surface will not produce fracture phenomenon；Increase 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 continued-mounted high performance corrosion-proof elbow.
In figure: 1- steel shell, 2- connecting flange, 3- adjusting pad, 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 continued-mounted high performance corrosion-proof elbow, including elbow body, the elbow body include steel
Steel shell 1, the steel shell is arranged in shell 1, connecting flange 2, adjusting pad 3 and backing layer fluoroplastics 4 processed, the elbow body
Body 1 is die casting and molding structure, and connecting flange 2 is arranged in the end of steel shell 1, and the steel shell 1 is adopted with connecting flange 2
With casting integrated formula structure, the inside of no-welding-seam between connecting flange 2 and steel shell 1, the elbow body is equipped with backing layer
Fluoroplastics 4, the backing layer fluoroplastics 4 use polytetrafluoroethylene PTFE plate, are coated on overcurrent position and flange in elbow
On sealing surface, therefore there is extraordinary antiseptic property, using there is not aliquation under high/low temperature and high vacuum, bulge is described
Adjusting pad 3 is provided in elbow body, the adjusting pad 3 is installed on 4 flange sealing surface of backing layer fluoroplastics and steel flanges are close
Position between envelope.
The connecting flange 2 includes two parts of backing layer fluoroplastics flange and steel flanges.
It is unable to high-low temperature resistant, high negative pressure when existing corrosion-resistant elbow is because using, circular arc degree is larger, leads to production system
Difficult raising cost is made, causes product repairing inconvenient, in use backing layer meeting aliquation, drum under high/low temperature, high vacuum
Packet, flange sealing surface when expanding with heat and contract with cold in use can produce fracture at camber minimum.
Improved continued-mounted high performance corrosion-proof elbow pass through structural improvement and optimization, steel shell 1 with connect
Flange 2 uses casting integrated formula structure, no-welding-seam phenomenon between connecting flange 2 and elbow body, and backing layer fluoroplastics 4 use plate
Material Pian tight liner combination process uses rough processing using segmentation structure on steel flanges sealing surface, steel inner wall removes coarse sand
Rust, Pian tight liner is compound to use novel high-low temperature resistant glue barbola work, and backing layer fluoroplastics plate does not need progress sodium and fluorine is gone to remove
Reason, increases by one layer of high-low temperature resistant adjusting pad 3 between backing layer fluoroplastics flange sealing surface and steel flanges sealing, adjusting pad 3 increases
The influence for having added leakproofness and system to expand with heat and contract with cold, while circular arc together is formd to corner between tube wall and flange, it prevents
It fractures when the sealing surface flange molding of backing layer fluoroplastics 4, it is cold by system heat expansion using major radius orthodrome is eliminated after segmentation
The influence of contracting connects dress formula high performance corrosion-proof elbow backing layer fluorine in this way when generating high/low temperature, high vacuum state in system
Plastics will not aliquation, phenomena such as bulge, sealing surface will not produce fracture phenomenon；Increase product service life by 2 times, reduces user
Purchase cost about 40%~50%.
So being very suitable for using on the etch-proof working condition of Large diameter.To provide a kind of sealing performance
It is good, economical and practical, corrosion resistance is high, the continued-mounted high performance corrosion-proof elbow of high-low temperature resistant, high vacuum, long service life etc..
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.
