Description
Technical field
The utility model relates to flange more particularly to a kind of protective devices of the internal expansion type flange sealing surface for pipeline.
Background technique
Before pipeline coating spray painting, need to carry out blasting treatment to process pipelines single tube surface, so that pipeline reaches painting
Reload request.However, due to during carrying out blasting treatment to pipeline outer surface, the flange seal of single tube underwater flange nozzle
Face is easily broken by abrasive material；And since abrasive material is easy to enter inside process pipelines from open flange port, so as to cause technique
The wall polluting of pipeline；Therefore, after sandblasting, need to clear up pipeline abrasive material.So, not only pipeline is not easily cleaned completely；And
And in pipeline transportation, storage and installation link, it is subject to extraneous hard object and collides with, scratches or natural force raindrop erosion
Damage, to cause the flange face rehabilitation expense of great number.
To overcome the above disadvantages, in general, in pipeline coating spray painting, transport, storage and installation, using plastic tube
Cap protection pipe or the mode for using rubber or canvas, block underwater flange nozzle.But above-mentioned material is in pipeline method
Blue nozzle is prefabricated and transportational process in, be not only easy to fall off, lose or grind it is rotten, moreover, cannot recycle and recycle；Meanwhile
It is also easy in sandblasting, is broken by high speed and high pressure abrasive material；So, it is not only brought to sequent surface processing and coating certain
Therefore difficulty, causes to repair the costly of flange face moreover, can also damage flange sealing surface.
Utility model content
The main purpose of the utility model is to overcome disadvantages mentioned above of the existing technology, and provide a kind of internal expansion type method
The protective device of blue sealing surface can not only block underwater flange nozzle, solve in sandblasting, underwater flange pipe
Mouthful flange sealing surface easily broken by high speed and high pressure abrasive material and collided with by extraneous hard object in transport, storage, installation link,
The problem of corrosion damage caused by scuffing or natural force rainwater；Moreover, in pipeline precast and transportational process, it is not easy to de-
It falls, lose, and can be recycled；The protective to underwater flange nozzle is substantially increased, energy-saving and emission-reduction are reached, cost efficiency
Purpose.
The purpose of this utility model is realized by the following technical solutions:
A kind of protective device of internal expansion type flange sealing surface, it is characterised in that: include: that center threaded rod, movable set exist
Bullet on the threaded rod of center, wherein bullet includes: two the first bullets and the second bullet being oppositely arranged, the
One bullet, the second bullet center be equipped with one for the through-hole that is sleeved on the threaded rod of center；Wherein, outside the first bullet
It is set with the first locking nut on the center threaded rod of side, it is short that positioning is set on the center threaded rod in the outside of the second bullet
Section, the side of orientation spool is equipped with the second locking nut；Flange port is installed between second locking nut and orientation spool
Protective cover, flange port protective cover are equipped with the silicagel pad being bonded with the sealing surface of flange port.
The bullet is expansion chuck, bullet inside, it may be assumed that be equipped between the first bullet and the second bullet outward
Swelling rubber bodies.
The utility model has the beneficial effects that the utility model is due to the adoption of the above technical scheme, structure is simple, solid resistance to
With, underwater flange nozzle can not only be blocked, be solved in sandblasting, the flange sealing surface of underwater flange nozzle easily quilt
High speed and high pressure abrasive material breaks and collided with by extraneous hard object in transport, storage, installation link, scratched or natural force rainwater institute
The problem of caused corrosion damage；Moreover, in pipeline precast and transportational process, it is not easy to fall off, lose, and recyclable benefit
With；The protective to underwater flange nozzle is substantially increased, energy-saving and emission-reduction, the purpose of cost efficiency are reached.
