Abstract
The utility model discloses an outer anticorrosive subassembly of spraying of interior isolation, including steel body, be equipped with the annular boss coaxial with the body on the body tip inner wall, annular boss inner edge is equipped with the annular groove, be equipped with in the annular groove rather than the sealed annular latex circle that bonds of cooperation, annular latex circle inner edge is equipped with the latex film, latex film and annular latex circle integrated into one piece, isolation parts is constituteed to annular latex circle, latex film and annular boss, body cooperation between isolation parts and the isolation parts forms keeps apart the region, the spraying of body outer wall has an epoxy layer, is equipped with the spiral steel wire line around epoxy layer outer wall, it has emulsion layer to go back the spraying outside the epoxy layer, between spiral steel wire line embedding emulsion layer and the epoxy layer. The preservation of body inside and outside wall can be played through the anticorrosive subassembly that uses this application.
Description
Technical field
The utility model relates to a kind of interior isolation trypsin method corrosion resistant component.
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 a kind of interior isolation trypsin method corrosion resistant component of body inside and outside wall favorable anti-corrosion effect.
Summary of the invention
The purpose of this utility model is to overcome the defect existed in prior art, provides prior art to be badly in need of a kind of interior isolation trypsin method corrosion resistant component of body inside and outside wall favorable anti-corrosion effect.
For achieving the above object, the technical solution of the utility model there is provided a kind of interior isolation trypsin method corrosion resistant component, comprise the body of steel, described body inner wall of end is provided with the annular boss coaxial with body, described annular boss inner edge is provided with annular groove, be provided with in described annular groove and be mated the bonding annular latex circle of sealing, described annular latex circle inner edge is provided with latex film, described latex film and annular latex circle one-body molded; Annular latex circle, latex film and annular boss composition isolating part, described isolating part coordinates with the body between isolating part and forms area of isolation; Described tube wall is coated with epoxy resin layer, is provided with spiral wire line around epoxy resin layer outer wall, and described epoxy resin layer is also coated with latex layer outward, and described spiral wire line embeds between latex layer and epoxy resin layer.Area of isolation can be formed by pipe by using the corrosion resistant component of the application; stop erosion to contact with inboard wall of tube body; effectively play the antisepsis of inboard wall of tube body; can be protected outer wall by the epoxy resin layer of outside; improved the fastness of epoxy resin layer by spiral wire line, latex layer improves contact feel.
As preferably, described spiral wire line and epoxy resin layer form close contact by winding tensions.Such design makes epoxy resin layer difficult drop-off.
As preferably, described latex layer thickness is 3-5mm.Such thickness can protect spiral wire line, can obtain good feel again, production control cost.
Advantage of the present utility model and beneficial effect are: can form area of isolation by pipe by using the corrosion resistant component of the application; stop erosion to contact with inboard wall of tube body; effectively play the antisepsis of inboard wall of tube body; can be protected outer wall by the epoxy resin layer of outside; improved the fastness of epoxy resin layer by spiral wire line, latex layer improves contact feel.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is spiral wire line distribution schematic diagram before latex spray.
In figure: 1, body; 2, annular boss; 3, annular latex circle; 4, latex film; 5, epoxy resin layer; 6, drying part; 7, spiral wire line; 8, latex layer.
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 depicted in figs. 1 and 2, isolation trypsin method corrosion resistant component in a kind of, comprise the body 1 of steel, described body 1 inner wall of end is provided with the annular boss 2 coaxial with body 1, described annular boss 2 inner edge is provided with annular groove, be provided with in described annular groove and be mated the bonding annular latex circle 3 of sealing, described annular latex circle 3 inner edge is provided with latex film 4, and described latex film 4 is one-body molded with annular latex circle 3; Annular latex circle 3, latex film 4 and annular boss 2 form isolating part, and described isolating part coordinates with the body 1 between isolating part and forms area of isolation; Described body 1 outer wall is coated with epoxy resin layer 5, is provided with spiral wire line 7 around epoxy resin layer 5 outer wall, and described epoxy resin layer 5 is outer is also coated with latex layer 8, and described spiral wire line 7 embeds between latex layer 8 and epoxy resin layer 5.Latex film 4 in isolating part and annular latex circle 3 have certain elasticity, such material can so that install, after installing simultaneously, the Volume Changes that in body 1, gas brings because of exterior temperature change can be balanced by the elasticity of latex film 4, no matter be the gas pressure that thermal expansion or cold events can alleviate annular groove and annular latex circle 3 auxiliary section, prevent isolating part to lose efficacy.
Described spiral wire line 7 forms close contact with epoxy resin layer 5 by winding tensions.
Described latex layer 8 thickness is 3-5mm.
During use, in annular groove, apply sealer, be expressed in annular groove by annular latex circle 3 by external pressure, annular groove is preferably major arc groove, not easily eject after so annular latex circle 3 snaps in, by sealer, annular latex circle 3 and annular groove are sealed bonding; Annular latex circle 3, latex film 4 and annular boss 2 form isolating part.Now body 1 outer wall and body 1 inner wall surface of not isolating thereof are carried out to the spraying of epoxy resin, epoxy resin has excellent corrosion resistance, adhesion and wear-resisting property, effectively resists the corrosion of acidic materials, simultaneously long service life.By winding mechanism, spiral wire line 7 is spirally wound on epoxy resin layer 5 outer wall with certain winding pressure, spiral wire line 7 two ends and body 1 are fixed, then spray latex layer 8.In order to keep the drying in area of isolation, can drying part 6 be set in area of isolation.
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.
