Background technique
At present, the construction of PE pipeline connects by existing international mode and mainly comprises three kinds of hot melt butt joint, electric smelting connection and mechanical connections.Wherein, it all is to adopt the hot melt butt joint that heavy caliber pipe, pipe fitting connect, described hot melt connect be with after tubing or the pipe fitting fusing earlier again polymerization link into an integrated entity.Minor caliber pipe goes out because the effect of pressure can produce molten seborrhea when adopting the hot melt butt joint, causes its internal diameter to dwindle, and it is unimpeded to influence current.And the PE tubing that has steel-wire carcass is when connecting; owing to can't implement the hot melt butt joint; therefore must adopt electric smelting sleeve welding manner; electric smelting sleeve complicated operation; molten fat visibility is zero; resistance wire short circuit or the unstable situation of welding occur through regular meeting, and then cause the electric smelting sleeve to scrap, strengthened construction cost.In addition, electric smelting connects all needs long electric smelting heating time and cool time, so influenced pipeline construction efficient.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, be convenient to on-site construction operations and can shorten the cold coupling sleeve of PE pipeline of pipeline construction activity duration and cost significantly.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The cold coupling sleeve of PE pipeline, comprise sleeve body, it is characterized in that: described sleeve body is the two layered cylinder wall construction that axial intermediate portion is provided with connecting body, symmetry is provided with flexible buffer portion and shutoff sleeve embedded part successively between the double-deck barrel in connecting body both sides, is shaped on the slot for plug-in mounting hot melt fixed block on the circumference of described sleeve body two ends;
Comprise that also interference is fitted in shutoff sleeve embedded part on the sleeve body, shutoff sleeve that its external diameter is the undergauge structure and is inserted into hot melt fixed block in the slot, shutoff sleeve one end circumference is provided with the slot for plug-in mounting hot melt fixed block.
The utility model can also adopt following technological scheme:
Described sleeve body and shutoff sleeve all adopt the PE plastic production.
The flexible buffer portion of described sleeve body is to be made of a plurality of continuous circular-arc buffer substrate tablet that is fixed between the double-deck barrel of sleeve body.
The flexible buffer portion of described sleeve body is to be made of a plurality of continuous N shape buffer substrate tablet that is fixed between the double-deck barrel of sleeve body.
Described sleeve body two ends are shaped on the recessed seam for the location, and described shutoff sleeve one end outside is shaped on the male half coupling that cooperates with the recessed seam of sleeve body.
At least be shaped on two symmetrically arranged slots for plug-in mounting hot melt fixed block on the circumference of described sleeve body two ends.
At least be provided with two symmetrically arranged slots for plug-in mounting hot melt fixed block on the described shutoff sleeve one end circumference.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, namely in the water supply line construction operation, adopt the cold coupling sleeve of this PE pipeline pipeline can be implemented to be connected sealing with pipe end, need not electric smelting heating time and cool time, avoided the unstable defective of resistance wire short circuit or welding, not only be convenient to on-site construction operations, simple installation and shorten the pipeline connection activity duration fast, significantly, but also can guarantee the pipeline quality of connection, reduce the pipeline construction cost greatly.The defective that stability, ductility, pliability and the memory function thereof that this cold coupling sleeve has by the PE material connects electric smelting connection or hot melt can play well to repair ends effect; Because ring compression effect in the pipeline, namely manifold pressure is more big, and its sealing is more good, and can increase the service life significantly.
