Description
Technical field
The utility model relates to PE tubing field, particularly a kind of be provided with electric fuse for bigbore PE pipe patch.
Background technique
Polyethylene (PE) pipeline welds (welding) property, (heat-melting butt-joint, electric smelting connection) easy to connect, splitting resistance, environmental protection, health, the advantage such as recyclable because it is unique and good, become the optimal selection of city gas transmission network, mesolow water pipe.
In actual use, plastic tube is identical with traditional metal tube, all there is the problem of repairing.When PE pipeline occurs that breakage is, need one of breakage section to cut out, change new pipeline.Such as, when natural gas line occurs damaged, owing to cutting out the pipeline of this breakage, therefore air feed total valve must first be closed, again ducted rock gas is bled off and more could renew pipeline, thus ducted rock gas is wasted, what also affect natural gas user uses gas simultaneously, and the engineering time is long, waste a large amount of manpower and materials, fix rear needs again gas testing supply gas.
Therefore, in order to solve the problem that prior art causes owing to will cut off damaged pipeline, electric melting patch is developed.Such as application number is that the utility model patent of 200920230315.X discloses a kind of PE pipeline electric melting patch, and be built-in with electric heating wire at the interlayer of electric melting patch, the two ends of electric heating wire are separately fixed on the attachment post on electric melting patch; The shape of electric melting patch adopts the tile matched with PE outer diameter tube; Two axial limits of electric melting patch are provided with the tightening nut of fixing fixing belt; Electric melting patch adopts the material identical with PE pipeline.
Application number be 200520057167.8 utility model patent disclose a kind of saddle electric-smelting patching piece for plastic pipe, comprise saddle polymer patch plate, the inwall saddle face of saddle polymer patch plate is provided with saddle electrical heater plater, and the outer side surface of saddle polymer patch plate is provided with the both positive and negative polarity copper electrode be connected with saddle electrical heater plater.Saddle polymer patch plate is provided with the overflow hole identical with saddle face inside it; Saddle electrical heater plater sticks in the resistance alloy in its spiral groove on surface by saddle liner and hot pressing, and the positive and negative copper electrode being connected to resistance alloy two ends is formed; Saddle face, the inner side symmetry of saddle polymer patch plate offers the through hole of two power supply sources connections; Saddle polymer patch plate outer side surface correspondence and two through hole position are respectively equipped with the mounting hole that electrode tip holder embeds; Positive and negative copper electrode is arranged in saddle polymer patch plate outer side surface mounting hole by electrode tip holder.
But, existing electric melting patch is all adopt overall surrounding type, the outer surface of whole PR tubing all can melted by heat under the effect of heating wire again, be out of shape after but the melted by heat of whole PE outer pipe wall easily causes tubing condensation, particularly for heavy caliber pipe, if the whole outer wall of tubing is all heated, condensed pipe deformations amount is larger.
