Description

The cold coupling sleeve of PE pipeline
Technical field
The invention belongs to the pipeline connection technology field, particularly relate to the cold coupling sleeve of a kind of PE pipeline.
Background technique
At present, the construction of PE pipeline connects by existing international mode and mainly comprises three kinds of heat-melting butt-joint, electric smelting connection and mechanical connections.Wherein, it is all to adopt heat-melting butt-joint that heavy caliber pipe, pipe fitting connect, described hot melt connect be after tubing or pipe fitting are first melted again polymerization link into an integrated entity.Minor caliber pipe goes out because the effect of pressure can produce molten seborrhea when adopting heat-melting butt-joint, causes its internal diameter to dwindle, and affects current unimpeded.And when connecting with the PE tubing of steel-wire carcass; owing to can't implementing heat-melting butt-joint; therefore must adopt the electric melting sleeve welding manner; the electric melting sleeve complicated operation; molten fat visibility is zero; the unstable situation of resistance wire short circuit or welding often can occur, and then cause electric melting sleeve to scrap, strengthen construction cost.In addition, electric smelting connects all needs electric smelting heating time and cool time of growing, therefore affected pipeline construction efficient.
Summary of the invention
The present invention for solve the technical problem that exists in known technology provide a kind of simple in structure, be convenient to on-site construction operations and can significantly shorten the cold coupling sleeve of PE pipeline of pipeline construction activity duration and cost.
The technological scheme that the present invention takes 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 with 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 sleeve body, shutoff sleeve that its external diameter is the undergauge structure and is inserted into hot melt fixed block in slot, shutoff sleeve one end circumference is provided with the slot for plug-in mounting hot melt fixed block.
The present invention 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 connected 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 connected N shape buffer substrate tablet that is fixed between the double-deck barrel of sleeve body.
Described sleeve body two ends are shaped with the recessed seam for the location, and described shutoff sleeve one end outside is shaped with the male half coupling that coordinates with the recessed seam of sleeve body.
At least be shaped with 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 described shutoff sleeve one end circumference.
Advantage and good effect that the present invention has are: because the present invention 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 fast, significantly shorten the pipeline connection activity duration, but also can guarantee the pipeline quality of connection, greatly reduce the pipeline construction cost.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 repaiies only effect; Due to ring compression effect in pipeline, namely manifold pressure is larger, and its sealing is better, and can significantly increase the service life.
