Abstract
The utility model discloses a packing has anticorrosive subassembly of meeting water expansion glue, including steel body, be equipped with compound gasbag on the body tip inner wall, compound gasbag includes outer gasbag and sets up at polite for regarding oneself as a stranger or outsider in intracapsular gasbag, form fill area between interior gasbag and the outer gasbag, the fill area intussuseption is filled with meets water expansion glue, be equipped with the water filling port on the outer gasbag, outer gasbag outer wall bonds with pipe inner wall, body between compound gasbag and the compound gasbag constitutes closed areas, the coating of body outer wall has the epoxy layer. Thing and pipe inner wall contact, the effectual preservation that plays pipe inner wall can be stopped to corrode with intraductal formation closed areas by anticorrosive subassembly through using this application, better protection can be carried out by the external wall of geminate transistors in the epoxy layer.
Description
Technical field
The utility model relates to a kind of corrosion resistant component being filled with water-swellable glue.
Background technique
Existing engineering pipe, pipe fitting in particular for iron skill is steel pipe, in the maintenance process in later stage, need that regular to carry out japanning to body antirust, body is hollow tubular, after first japanning, in maintenance process, inwall japanning is carried out very not easily to already installed body, only to coated outside, inwall is easy to get rusty, from internal damage under comparatively moist or corrosion-prone environment.Prior art is badly in need of all good corrosion resistant component being filled with water-swellable glue of a kind of body inside and outside wall antiseptic effect.
Summary of the invention
The purpose of this utility model is to overcome the defect existed in prior art, the corrosion resistant component being filled with water-swellable glue that a kind of body inside and outside wall antiseptic effect providing prior art to be badly in need of is all good.
For achieving the above object, the technical solution of the utility model there is provided a kind of corrosion resistant component being filled with water-swellable glue, comprise the body of steel, described body inner wall of end is provided with composite air bag, described composite air bag comprises outer air bag and is arranged on the interior air bag in outer air bag, forms fill area between described interior air bag and outer air bag; Be filled with water-swellable glue in described fill area, described outer air bag is provided with water filling hole; Described outer gasbag ektexine is bonding with inboard wall of tube body, and the body between described composite air bag and composite air bag forms closed area; Described tube wall is coated with epoxy resin layer.By using the corrosion resistant component of the application can form closed area by pipe, stopping erosion and contacting with inboard wall of tube body, effectively playing the antisepsis of inboard wall of tube body; Epoxy resin layer can be protected preferably to tube wall.
As preferably, in described interior air bag, be filled with gas.Such design is convenient to install, and inflates, also save the installation of each air bag air valve when saving installation to each air bag.
As preferably, described water filling hole is arranged towards body outer end.Water filling is convenient in such design.
Advantage of the present utility model and beneficial effect are: by using the corrosion resistant component of the application can form closed area by pipe, stopping erosion and contacting with inboard wall of tube body, effectively playing the antisepsis of inboard wall of tube body; Epoxy resin layer can be protected preferably to tube wall.

Fig. 1 is the utility model structural representation.
In figure: 1, body; 2, composite air bag; 3, water filling hole; 4, sealer; 5, closed area; 6, drying part; 7, epoxy resin layer; 8, outer air bag; 9, interior air bag; 10, fill area.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of corrosion resistant component being filled with water-swellable glue, comprise the body 1 of steel, described body 1 inner wall of end is provided with composite air bag 2, the interior air bag 9 that described composite air bag 2 comprises outer air bag 8 and is arranged in outer air bag 8, forms fill area 10 between described interior air bag 9 and outer air bag 8; Be filled with water-swellable glue in described fill area 10, described outer air bag 8 is provided with water filling hole 3; Described outer air bag 8 outer wall is bonding with body 1 inwall, and the body 1 between described composite air bag 2 and composite air bag 2 forms closed area 5; Described body 1 outer wall is coated with epoxy resin layer 7.
Gas is filled with in described interior air bag 9.Suppress it inwardly expand then outwards expand when water-swellable glue expands.
Described water filling hole 3 is arranged towards body 1 outer end.Such setting is except facilitating water filling, when humid environment, the air of external humidification can enter fill area 10 by water filling hole 3 and excite water-swellable glue to expand, even if the bonding failure of later stage outer air bag 8 and body 1 inwall, under malaria environment, moist, the isolation effect of composite air bag 2 is better.
Drying part 6 is provided with in described closed area 5.Keep air oxygen detrition in closed area 5, prevent inner wall corrosion further.
During use, body 1 inwall applies the preferred AB glue of sealer 4(), the composite air bag 2 being filled with gas in interior air bag 9 is in advance placed on and body 1 inner wall position applying salable glue 4, then in fill area 10, rational water is injected by water filling hole 3, water-swellable glue in fill area 10 meet water after volumetric expansion, force outer air bag 8 outer wall and body 1 inwall mutually to extrude to coordinate bonding; Keep pressure a period of time, after glue 4 to be sealed solidifies, body 1 is just isolated by composite air bag 2, arranges this parts in all ends of body 1, just forms closed area 5 by body 1, the corrosion of isolation erosion.Water-expansible rubber is a kind of rubber new product of uniqueness.The performance of its existing general rubber product, can meet again the performance of water self-expansion, be a kind of new material such as patent No. is the hydro-expansive rubber mentioned in 201110028658.X.
Body 1 inwall that is outside to body 1 and that do not isolate carries out the spraying of epoxy resin, reaches the corrosion protection of body 1 outer wall.Epoxy resin has excellent corrosion resistance, adhesion and wear-resisting property, effectively resists the corrosion of acidic materials, simultaneously long service life.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing from the front lower of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
