Abstract
The utility model discloses an ultrasonic bonding seal assembly, including steel body, be close to and be equipped with isolation parts on the pipe inner wall of body tip, isolation parts include interior spraying plastics anchor ring and with the barrier film of interior spraying plastics anchor ring 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 ultrasonic welding black box.
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 ultrasonic welding black box 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 ultrasonic welding black box 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 ultrasonic welding black box, comprise the body of steel, be provided with isolating part near the inboard wall of tube body of body end, described isolating part comprise internal plastic spraying anchor ring and with the isolating film of internal plastic spraying anchor ring 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, described inboard wall of tube body is provided with smooth annular surface, described smooth surface is coated with PE layer, and described PE layer covers smooth annular surface and forms internal plastic spraying anchor ring.The adhesive strength of PE layer and inboard wall of tube body is strengthened in such design.
As preferably, described isolating film comprises ring surface sidewall and is arranged on bottom surface, described annular sidewall and the ultrasonic welding of internal plastic spraying anchor ring of ring surface sidewall one end.Such design makes the existing junction surface of isolating film (annular sidewall) have again isolation surface (bottom surface).The preferred PE of described 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.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, body; 2, internal plastic spraying anchor ring; 3, sealing area; 4, ring surface sidewall; 5, epoxy resin protective layer; 6, bottom surface.
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 ultrasonic welding black box, comprises the body 1 of steel, is provided with isolating part near body 1 inwall of body 1 end, described isolating part comprise internal plastic spraying anchor ring 2 and with the isolating film of internal plastic spraying anchor ring 2 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.
Described body 1 inwall is provided with smooth annular surface, described smooth surface is coated with PE layer, and described PE layer covers smooth annular surface and forms internal plastic spraying anchor ring 2.
Described isolating film comprises ring surface sidewall 4 and is arranged on bottom surface 6, described annular sidewall and internal plastic spraying anchor ring 2 ultrasonic welding of ring surface sidewall 4 one end.Described bottom surface 6 is arc shaped surface, can axially inwardly or be bent outwardly, the Volume Changes that such design can be brought because of exterior temperature change by gas in balance body 1 bending inside and outside bottom surface 6, no matter be the gas pressure that thermal expansion or cold events can alleviate ultrasonic welding portion, prevent isolating film fracture failure.
When making, first body 1 inwall coordinates the position inwall of ultrasonic welding to clean, after oven dry, plastic-blasting is carried out to it, form internal plastic spraying anchor ring 2, then isolating film cup-shaped for opening is placed and cooperation position, outward opening, by ultrasonic welding ring surface sidewall 4 coordinated with internal plastic spraying anchor ring 2 and weld, now body 1 is isolated into interior exterior domain by isolating film, carries out aforesaid operations in the end of body 1, just forms sealing area 3 in body 1; 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.
