Abstract
The utility model discloses an anticorrosive subassembly with inflation cover, including steel body, be equipped with the inflation cover on the body tip inner wall, the inflation cover is the spherical cavity latex cover of circle, the intussuseption of inflation cover is filled with meets water expansion glue, the inflation is sheathe in and is equipped with the water filling port, the water filling port inboard is provided with the water injection pipe, the play water end (W. E. ) of water injection pipe inserts meets water expansion glue center, inflation cover outer wall is smooth surface, pipe inner wall is smooth surface, inflation cover outer wall constitutes closed areas with pipe inner wall through sealed sticky connecing, the body between inflation cover and the inflation cover, 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 provided with expansion sleeve.
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 provided with expansion sleeve 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 provided with expansion sleeve 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 provided with expansion sleeve, comprise the body of steel, described body inner wall of end is provided with expansion sleeve, described expansion sleeve is the hollow rubber finger sleeve of spheroidal, is filled with water-swellable glue in described expansion sleeve, and described expansion sleeve is provided with water filling hole, be provided with water injecting pipe inside described water filling hole, water-swellable glue central position is inserted in the waterexit end of described water injecting pipe; Described expansion sleeve outer wall is smooth surface, and described inboard wall of tube body is smooth surface, and described expansion sleeve outer wall is bonding by sealer with inboard wall of tube body, and the body between expansion sleeve and expansion sleeve 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, water-swellable glue is that spherical particle is filled in expansion sleeve inside.Such design makes expansion glue be arranged on expansion sleeve inside comparatively uniformly.
As preferably, described epoxy resin layer is sprayfused coating.Epoxy resin has excellent corrosion resistance, adhesion and wear-resisting property, effectively resists the corrosion of acidic materials, simultaneously long service life.Spraying method operation is easier.
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.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, body; 2, expansion sleeve; 3, water filling hole; 4, sealer; 5, closed area; 6, drying part; 7, epoxy resin layer; 8, water injecting pipe; 9, water-swellable glue.
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 provided with expansion sleeve, comprise the body 1 of steel, described body 1 inner wall of end is provided with expansion sleeve 2, described expansion sleeve 2 is the hollow rubber finger sleeve of spheroidal, is filled with water-swellable glue 9 in described expansion sleeve 2, and described expansion sleeve 2 is provided with water filling hole 3, be provided with water injecting pipe 8 inside described water filling hole 3, water-swellable glue 9 central position is inserted in the waterexit end of described water injecting pipe 8; Described expansion sleeve 2 outer wall is smooth surface, and described body 1 inwall is smooth surface, and described expansion sleeve 2 outer wall is bonding by sealer 4 with body 1 inwall, and the body 1 between expansion sleeve 2 and expansion sleeve 2 forms closed area 5; Described body 1 outer wall is coated with epoxy resin layer 7.
The setting of water filling hole 3 is except facilitating water filling, when humid environment, the air of external humidification can be entered in expansion sleeve 2 by water filling hole 3 and excite water-swellable glue 9 to expand, even if the adhesive failure of late expansion cover 2 and body 1 inwall, under malaria environment, moist, the isolation effect of expansion sleeve 2 is better.
Water-swellable glue 9 is filled in expansion sleeve 2 in spherical particle inner.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.
Described epoxy resin layer 7 is sprayfused coating.
Drying part 6 is provided with in described closed area 5
During use, body 1 inwall applies sealer 4, expansion sleeve 2 is placed on and body 1 inner wall position being coated with sealer 4, by water filling hole 3 to water filling in body 1, volumetric expansion after water met by water-swellable glue 9, outer wall and body 1 inwall of expansion sleeve 2 mutually extrude coordinate bonding; Keep pressure a period of time, after glue 4 to be sealed solidifies, body 1 is just isolated by expansion sleeve 2, arranges this parts in all ends of body 1, just forms closed area 5 by body 1, the corrosion of isolation erosion; Good body 1 inwall of not isolating in body 1 outside is carried out to the spraying of epoxy resin, reach the corrosion protection of body 1 outer wall.
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.
