Abstract
The utility model discloses an electromagnetic induction steel -plastic compler pipeline butt fusion structure belongs to pipeline connection technology field. Mould compound tubular product and plastics pipe fittings including the steel, plastics pipe fittings has the link of two at least intercommunications, and each link has outer loop portion, inner ring portion and forms tube end between outer loop portion and the inner ring portion, the steel is moulded compound tubular product and is had outer plastic layer, interior plastic layer and middle steel layer, at least, the outer wall in an inner ring portion has the external screw thread, compound tubular product system on the corresponding interior plastic layer of the external screw thread with inner ring portion is moulded to the steel has an internal thread, the steel is moulded the fixed plastics pipe fittings of arriving of compound tubular product threaded connection and is gone up the back, when this plastics pipe fittings's link outer loop week forms alternating magnetic field, the internal thread of compound tubular product is moulded to the steel, outer plastic layer respectively with plastics pipe fittings's external screw thread, the inner wall electromagnetism butt fusion of outer loop portion. After adopting above -mentioned technical scheme, it is big with plastics pipe fittings butt fusion area that compound tubular product is moulded to the steel, and the frit seal is effectual, the butt fusion high quality.
Description
[technical field]
This utility model relates to a kind of electromagnetic induction composite metal plastic pipe welding structure, belongs to technical field of pipeline connection.
[background technology]
Existing electromagnetic induction composite metal plastic pipe includes steel-plastic composite pipe and plastic pipe, outside steel-plastic composite pipe includes
Plastic layer, middle steel layer and inner plastic layer, and the connection end of plastic pipe is shaped with external annulus, internal ring wall and external annulus and internal ring wall
Surround supplies steel-plastic composite pipe grafting ring-type birdsmouth therein.Steel-plastic composite pipe inserts the ring-type birdsmouth of plastic pipe
In, from the periphery of plugging position, plugging position is applied induced field with electromagnetic induction heater afterwards so that steel-plastics composite pipe
Material is fused together with plastic pipe.
Carefully analyze said structure, it is seen that there is following technical deficiency:
1, steel-plastic composite pipe is little with plastic pipe welding area, and frit seal poor effect exists hidden leakage defect;
2, the steel-plastic composite pipe after grafting is before welding, and it is unreliable that it is fixed with plastic pipe, and steel-plastic composite pipe is easy
Occur that skew walks, and then affect follow-up electromagnetic welding quality, and be not easy to that whole pipe network is fully under way efficiently carries out welding work
Industry.
[utility model content]
It is big that the purpose of this utility model is to provide a kind of welding area, the electromagnetism that frit seal is effective, welding quality is high
Sensing composite metal plastic pipe welding structure.
For solving above-mentioned technical problem, this utility model following technical scheme of offer:
Electromagnetic induction composite metal plastic pipe welding structure, including steel-plastic composite pipe and plastic pipe, plastic pipe has
The connection ends of at least two connections, each connect end have outer portion, internal ring portion and be formed at described outer portion and internal ring portion it
Between birdsmouth, steel-plastic composite pipe has outer plastic layer, inner plastic layer and middle steel layer, and its improvement is: at least one
The outer wall of individual internal ring portion has external screw thread, and steel-plastic composite pipe is shaped with on the inner plastic layer corresponding with the external screw thread of internal ring portion
One internal thread segment, steel-plastic composite pipe is threaded be fixed on plastic pipe after, this plastic pipe connection end outer shroud week
When forming alternating magnetic field, the internal thread segment of steel-plastic composite pipe, outer plastic layer respectively with in the external screw thread of plastic pipe, outer portion
Wall electromagnetic welding.
As preferentially, the outer wall of above-mentioned internal ring portion is formed with the sealing surface being positioned at above-mentioned external screw thread outer end.
As preferentially, above-mentioned sealing surface is rounded, and this circular seal face seals with inner plastic layer electromagnetic inductive welding.
The sealing surface set up can avoid liquid to enter in the birdsmouth of plastic pipe.
This utility model has the advantage that and useful good effect:
1, its inner plastic layer car of steel-plastic composite pipe is shaped with plastic whorl, not only makes steel-plastic composite pipe obtain full circle, protects
Demonstrate,prove fitness when being connected with plastic pipe, convenient and quick construction, and eliminate steel-plastic composite pipe when screw chasing
The oxide layer of its inner plastic layer, is conducive to improving welding quality;
2, the external screw thread that the internal ring portion of plastic pipe has is threaded for steel-plastic composite pipe, can realize steel-plastics composite pipe
Material is in plastic pipe to threaded and carries out electromagnetic welding under stationary state, both not off normals, facilitates whole pipe network welding to make
Industry smooth, efficiently carry out;
3, steel-plastic composite pipe and plastic pipe are with internal and external screw thread hot-melt adhesive paste, improve welding area, heat seal strength
Height, frit seal is better, and antiseep is satisfactory for result.
[accompanying drawing explanation]
Fig. 1 is section of structure of the present utility model.
[detailed description of the invention]
As it is shown in figure 1, electromagnetic induction composite metal plastic pipe welding structure, including steel-plastic composite pipe 2 and plastic pipe 1,
Plastic pipe 1 has the connection end 10 of at least two connections, and each end 10 that connects has outer portion 11, internal ring portion 12 and is formed at
Birdsmouth 13 between described outer portion 11 and internal ring portion 12, steel-plastic composite pipe 2 has outer plastic layer 21, inner plastic layer 22 and
Middle steel layer 23, its improvement is: at least outer wall at an internal ring portion 12 has external screw thread 120, and steel-plastic composite pipe 2 exists
An internal thread segment 220, steel-plastic composite pipe 2 screw thread it is shaped with on the inner plastic layer 22 corresponding with the external screw thread 120 of internal ring portion 12
After being affixed on plastic pipe 1, when the connection end 10 outer shroud week of this plastic pipe 1 forms alternating magnetic field, steel plastic compount
The internal thread segment 220 of tubing 2, outer plastic layer 21 respectively with external screw thread 120, the outer portion 11 inwall electromagnetic welding of plastic pipe 1.
In the present embodiment, the outer wall of the left and right internal ring portion of plastic pipe 1 is respectively provided with external screw thread as shown in the figure.
The sealing surface 121 being positioned at external screw thread 120 outer end it is formed with on the outer wall of internal ring portion 12.
Sealing surface 121 transition is connected at the outer end of external screw thread 120.
Sealing surface 121 is rounded, and this circular seal face seals with inner plastic layer 22 electromagnetic inductive welding.
