Description
Technical field
This utility model relates to pipe technology field, particularly relates to the particular manufacturing craft of a kind of non-digging PE-specialized double resistance to pipes.
Background technology
At present existing cable pipeline or pipeline use steel pipe mostly, generally use steel pipe to there is weight big, transport
Inconvenience, installs complexity, easy-to-rust, and the length of service is short, sealing property, heat resistance difference and by stress defect easy to crack, because of
This communication cable industry is in new pipeline technical standard, it is desirable to preferred material should select the double resistance to tubing of PE, and the double resistance to tubing of PE
In the connection on ground, general using straight tube docking, electrical heating is welded, and it is inflammable easily to be likely to be due to some in pipeline or pipeline
The reason of explosive gas etc., uses non-explosion-proof electrical heating operation not in down-hole, goes into the well after welding such as ground, and its length is the most very
Difficult adaptation conditions down-hole.
Utility model content
In order to solve above-mentioned technical problem, the purpose of this utility model is to provide a kind of non-digging PE-specialized double resistance to pipes
Particular manufacturing craft.
To achieve the above object, this utility model have employed following technical scheme:
The particular manufacturing craft of a kind of non-digging PE-specialized double resistance to pipes is provided, including back-up ring, inner mold body and outer mold body,
Wherein the double resistance to pipe clamp of PE is enclosed between inner mold body and back-up ring, and described inner mold body is torus shape, is against the double resistance to pipe of PE
On inwall, and between the back-up ring outer wall of resistance to pipe double with PE, interface width contacts equal between inner mold body resistance to inside pipe wall double with PE
Face width degree；Electric heating flaggy and heat-resisting stress crack resistant interlayer it is nested with the most successively being positioned at inside outer mold body；Institute
State outer mold body and withstand the double resistance to tube edge edge of PE.Wherein: heat-resisting stress crack resistant interlayer has prominent heat-resisting and stress crack resistant
Functional effect.
Preferably: the cross section of described outer mold body is symmetrical L-shaped structure.
Preferably: described outer mold body extends in the double resistance to pipe of PE, and in outer mold body resistance to pipe double with PE
Gap it is provided with between wall.
Compared with prior art, the beneficial effects of the utility model are:
The particular manufacturing craft of non-digging PE-specialized double resistance to pipes of the present utility model solves in cable pipeline or piping shaft to be taken out
Put flammable explosive gas and use the double resistance to tubing of PE, solve the problem that pipeline joint difficulty is big, it is achieved that manage integrated with back-up ring,
Alleviating deadweight, greatly facilitate transport and install, having simple in construction, flexible to operation, labor intensity is low, sealing property
Good, practical and attractive generous, profitable advantage；And heat-resisting stress crack resistant interlayer has prominent heat-resisting and stress crack resistant
Functional effect, it is ensured that the stability of this mould.
Simultaneously by controlling electric heating flaggy so that the double temperature stabilization of resistance to pipe of PE, i.e. realize the homogeneous heating of outer mold body,
And then the double resistance to pipe of PE is heated evenly, obtains good result；Electric heating flaggy uses electromagnetic heating technique, and its efficiency is high, preheating time
Short, service life is long, and heating part heat dissipates few, on production environment without impact.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Accompanying drawing marks: inner mold body 1, the double resistance to pipe 2 of PE, back-up ring 3, outer mold body 4, electric heating flaggy 5, heat-resisting proof stress
Cracking interlayer 6, gap 7.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is made a detailed explanation.
As it is shown in figure 1, this utility model provides being embodied as of the particular manufacturing craft of a kind of non-digging PE-specialized double resistance to pipes 2
Example, the particular manufacturing craft of a kind of non-digging PE-specialized double resistance to pipes 2 of this offer, including back-up ring 3, inner mold body 1 and outer mold body
4, wherein double resistance to pipe 2 chuck of PE is between inner mold body 1 and back-up ring 3, and described inner mold body 1, in torus shape, is against PE
On double resistance to pipe 2 inwalls, and between double resistance to pipe 2 outer wall of back-up ring 3 and PE, interface width is equal to inner mold body 1 resistance to pipe 2 double with PE
Interface width between inwall；Be positioned at inside outer mold body 4 be nested with the most successively electric heating flaggy 5 and heat-resisting resistance to should
Power cracking interlayer 6；Described outer mold body 4 withstands double resistance to pipe 2 edge of PE.Wherein: heat-resisting stress crack resistant interlayer 6 has prominent
The heat-resisting functional effect with stress crack resistant.
