Description
Technical field
The utility model relates to a kind of corrosion resistant component being provided with arc air bag.
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 arc air bag 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 arc air bag 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 arc air bag, 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 inflation area between described interior air bag and outer air bag; Be provided with isolating film in described inflation area, inflation area is divided into the annular air-pocket at a middle part and the arc air bag of both sides by described isolating film, the again sealed against one another isolation adjacent with arc air bag of described annular air-pocket; Described arc air bag is provided with inflation inlet, and described inflation inlet is communicated with by conduit, and the outer wall of arc air bag is provided with unidirectional gas charging valve; Described annular air-pocket outer wall 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, annular air-pocket and arc air bag, be filled with gas all in advance.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, the arc air bag inwall be positioned at inside body is provided with inflation inlet, and described inflation inlet is communicated with by conduit; The arc gasbag ektexine being positioned at outside is provided with unidirectional gas charging valve.Such design just can realize the inflation to two arc air bags by a unidirectional gas charging valve.
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.

In figure: 1, body; 2, composite air bag; 3, unidirectional gas charging valve; 4, sealer; 5, closed area; 6, drying part; 7, epoxy resin layer; 8, outer air bag; 9, interior air bag; 10, isolating film; 11, annular air-pocket; 12, arc air bag; 13, conduit.
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, be provided with a corrosion resistant component for arc air bag, 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 inflation area between described interior air bag 9 and outer air bag 8; Be provided with isolating film 10 in described inflation area, inflation area is divided into the annular air-pocket 11 at a middle part and the arc air bag 12 of both sides by described isolating film 10, the again sealed against one another isolation adjacent with arc air bag 12 of described annular air-pocket 11; Described arc air bag 12 is provided with inflation inlet, and described inflation inlet is communicated with by conduit 13, and the outer wall of arc air bag 12 is provided with unidirectional gas charging valve 3; Described annular air-pocket 11 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 all in advance in described interior air bag 9, annular air-pocket 11 and arc air bag 12.
Arc air bag 12 inwall be positioned at inside body 1 is provided with inflation inlet, and described inflation inlet is communicated with by conduit 13; Arc air bag 12 outer wall being positioned at outside is provided with unidirectional gas charging valve 3.
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, annular air-pocket 11 and arc air bag 12 all is in advance placed on and body 1 inner wall position applying salable glue 4, then inflated directly in arc air bag 12 by unidirectional gas charging valve 3, because the air pressure in arc air bag 12 increases, arc air bag 12 inwall can inwardly extrude, interior air bag 9 axial compression, radial expansion, forces annular air-pocket 11 radial expansion; Isolating film 10 oppressed by arc air bag 12 simultaneously, and isolating film 10 shrinks in annular air-pocket 11, and annular air-pocket 11 pressurized outwards expands; Comprehensive above two effects, annular air-pocket 11 outer wall and body 1 inwall mutually extrude 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; 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.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.
