Description
Technical field
This utility model belongs to conveyance conduit technical field, particularly to the attachment structure of a kind of pipeline.
Background technology
The sewage pipe that China's tradition is used mainly uses the tubing of the making such as cement, cast iron, fiberglass, and the sewage pipe quality that above material makes is heavy, service life is short, installation is complicated and construction cost is higher.In the last few years, drainage pipeline was widely used polyethylene plastic-steel winding pipe material.The advantages such as polyethylene plastic-steel winding pipe has that lightweight, inner wall smooth, critical external compressive resistance ability are strong, has telescopic adjustment function, eliminates stress rupture, corrosion-resistant.Polyethylene plastic-steel winding pipe is to be welded through spiral winding by the heterotypic strip of steel plastic compount, and forms at edge's overlap joint.The tubing of molding becomes the straight rib structure of spiral, is typically made up of the helical corrugation shape outer layer polyethylene of inner layer polyethylene, the steel band of spiral setting and outer layer, and helical steel band is arranged between outer layer polyethylene and inner layer polyethylene.
In the installation production technology of sewer pipe, generally requiring and dock two sewer pipes, the connected mode of existing plastic-steel spirally-wound pipe has two kinds, is that clamping hoop type elasticity connects and electric heating melting welds respectively.Clamping hoop type elastic connection way cannot ensure sewer pipe entirely without leakage, and fixing method complex operation, work efficiency is relatively low.
When using electric heating melting welding, impact due to job site environmental factors, easily make mains fluctuations too high, welding current can be caused excessive or weld interval is long, because electric heating merits and demerits cause greatly welding area to be heated excessively, make polyethylene plastic-steel winding pipe material overheated and do not support the bulbs of pressure of welding area polyethylene fusing, the welding area of tubing occurs raised or sunken, welding area is caused to deform, it is difficult to ensure firm welding, thus have impact on the quality that pipeline connects.Therefore, how to improve the quality of connection of plastic-steel spirally-wound pipe junction, become the technical barrier of this area.
Utility model content
In order to solve the problems referred to above that prior art exists, this utility model provides the attachment structure of the plastic-steel spirally-wound pipe that a kind of Electric thermal smelting belt is welded to connect conveniently, fastness is high, its reasonable in design, when connectivity port is in Electric thermal smelting belt welding, can be effectively combined, under the effect of internal support, it is ensured that the tubular form of weld, the variable-diameter structure affecting fluid can't be formed, it is ensured that the serviceability after firm welding degree and welding.
The technical scheme that this utility model is used is as follows:
A kind of plastic-steel-wound pipe connecting structure, it is characterised in that: including that body, described body include inner tube, said inner tube outer wall is wound around and is provided with steel band, and described steel band is fixed on outer wall of inner tube by clad；Connected by Electric thermal smelting belt between described each two body.
Described body two ends are respectively arranged with to be mutually butted and coordinate the connectivity port of inclination, and described body connectivity port is connected by Electric thermal smelting belt cladding.
Ring stiffness at described body connectivity port is identical with the ring stiffness of body.
Pitch at the width of described Electric thermal smelting belt and connectivity port is equal.
The inwall of described Electric thermal smelting belt is surrounded by one layer of electric heating fuse.
Said inner tube, clad, Electric thermal smelting belt are polythene material.
Technique scheme of the present utility model compared with prior art has the advantage that
(1) reasonable in design, before connectivity port is in electric heating melting welding, it is possible to effectively dock；
(2) under the effect of internal support, ensure that the tubular form of weld, avoid the generation that body junction is raised or sunken, make joint area identical with the diameter of body, ensure that the sealing property after firm welding degree and welding, stop the phenomenon that plastic-steel spirally-wound pipe joint leaks；
(3) material of connecting portion and the material of body are identical, and rotproofness is strong, use the cycle long.
