Abstract
The utility model discloses a seal assembly with fold, including steel body, be close to and be equipped with annular boss on the pipe inner wall of body tip, be equipped with isolation parts on the lateral surface of annular boss, isolation parts include the spraying plastics layer and with the spraying plastics layer barrier film through ultrasonic bonding, body between barrier film and the barrier film forms sealing region, the coating of body surface has epoxy protective layer. Through using this application seal assembly can form the contact that sealing region can keep apart the inner wall and corrode the thing in the body, epoxy protective layer can protect by the external wall of geminate transistors through the coating.
Description
Technical field
The utility model relates to the black box being provided with fold.
Background technique
As everyone knows, 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, but 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 the good black box being provided with fold of a kind of anticorrosion ability.
Summary of the invention
The purpose of this utility model is to overcome the defect existed in prior art, provides the black box being provided with fold that a kind of anticorrosion ability is good.
For achieving the above object, the technical solution of the utility model there is provided a kind of black box being provided with fold, comprise the body of steel, inboard wall of tube body near body end is provided with annular boss, the outer side surface of described annular boss is provided with isolating part, described isolating part comprise plastic-blasting layer and with the isolating film of plastic-blasting layer by ultrasonic welding; Body between isolating film and isolating film forms sealing area, and described outer surface of tube body is coated with epoxy resin protective layer.The contact that can form sealing area by using the black box described in the application in body and can isolate inwall and erosion, can protect tube wall by applying epoxy resin protective layer.
As preferably, the outer side surface of described annular boss is smooth annular surface, described smooth surface is coated with PE layer, and described PE layer covers smooth annular surface and forms plastic-blasting layer.The adhesive strength of PE layer and inboard wall of tube body is strengthened in such design.
As preferably, described isolating film comprises outside annular solder district and inner rounded fold district, and described annular solder district and inner rounded fold district are wholely set, and described rounded fold district comprises the fold ring connecting superposition from inside to outside successively.Such design can be expanded by the axial stretching function in rounded fold district or reduce the volume of sealing area, thus the Volume Changes that in balance body, gas brings because of exterior temperature change, no matter be the gas pressure that thermal expansion or cold events can alleviate ultrasonic welding portion, prevent isolating film fracture failure.The preferred PE of isolating film or aluminium coated material.
Advantage of the present utility model is with beneficial effect: can forming sealing area by using the black box described in the application in body and can isolate contacting of inwall and erosion, can protect by applying epoxy resin protective layer to tube wall.

In figure: 1, body; 2, smooth annular surface; 3, sealing area; 5, epoxy resin protective layer; 6, annular boss; 7, plastic-blasting layer; 8, annular solder district; 9, rounded fold district; 10, fold ring; 11, drying part.
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, a kind of black box being provided with fold, comprise the body 1 of steel, body 1 inwall near body 1 end is provided with annular boss 6, the outer side surface of described annular boss 6 is provided with isolating part, described isolating part comprise plastic-blasting layer 7 and with the isolating film of plastic-blasting layer 7 by ultrasonic welding; Body 1 between isolating film and isolating film forms sealing area 3, and described body 1 outer surface has epoxy resin protective layer 5.
The outer side surface of described annular boss 6 is smooth annular surface 2, described smooth surface is coated with PE layer, and described PE layer covers smooth annular surface 2 and forms plastic-blasting layer 7.
Described isolating film comprises outside annular solder district 8 and inner rounded fold district 9, and described annular solder district 8 and inner rounded fold district 9 are wholely set, and described rounded fold district 9 comprises the fold ring 10 connecting superposition from inside to outside successively.
In order to prevent there is humid air in sealing area 3, drying part 11 can be set in sealing area 3.
When making, first smooth annular surface 2 is cleaned, after oven dry, plastic-blasting is carried out to it, form plastic-blasting layer 7, then coordinated with 2 positions, smooth annular surface in annular solder district 8, carry out welded seal by ultrasound, now body 1 is isolated into interior exterior domain by isolating film, carry out aforesaid operations in the end of body 1, in body 1, just form sealing area 3; Then body 1 outer wall and body 1 inwall of not isolating thereof are carried out to the spraying of epoxy resin, form external protection.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.
