Description
Technical field
This utility model relates to compound pipeline complex pipeline technical field, is related specifically to a kind of multilamellar PE-RT/PE-Xb multiple
Close pipeline.
Background technology
The heat resistance (using as-70 DEG C~90 DEG C) that crosslinked polyethylene (PE-X) pipeline tool is excellent, relatively
In long service life, can use safely more than 50 years, good recovery shape-memory properties;Anti-vibration,
Impact resistance;Hydraulic characteristic(s) is excellent, is mainly used in the conveying of Indoor Thermal waterpipe, especially hot water.But
It is due to the special structure of crosslinked polyethylene, it is impossible to as the pipeline of thermoplastic, carry out hot-melt adhesive paste,
Its connected mode can only carry out mechanical connection, causes the reliability and security of its joint to be beaten greatly, detains,
Situation about usually leaking in junction.And then during developer have developed as depicted in figs. 1 and 2
State's patent one can hot melt PE-X compound pipeline complex pipeline, Application No. 201420488005.9, use bilayer multiple
Close structure, by can the PE-RT outer layer (2) of hot-melt adhesive paste and PE-X internal layer (1) constitute, PE-RT
Although this compound pipeline complex pipeline is linked together firmly by the method that outer layer can use hot melt with pipe fitting, but by
It is containing the composition such as organotin and silane in PE-X inner layer pipe, poor for delivery sanitation performance,
Especially domestic water, brings bigger harm to user.
But for the deficiencies in the prior art, developer be necessary to develop a kind of reasonable in design, simple in construction,
By the method for hot melt, pipeline can be linked together firmly with pipe fitting, it is possible to effectively avoid at pipe
There is situation about leaking, the multilamellar PE-RT/PE-Xb multiple tube that sanitation performance is good in the junction of road and pipe fitting
Road.
Utility model content
For solving the problem that prior art exists, this utility model provide a kind of reasonable in design, structure is simple
Singly, by the method for hot melt, pipeline can be linked together firmly with pipe fitting, it is possible to effectively avoid
Situation about leaking occur in the junction of pipeline Yu pipe fitting, multilamellar PE-RT/PE-Xb that sanitation performance is good is combined
Pipeline.
For solving above technical problem, this utility model realizes by the following technical solutions:
A kind of multilamellar PE-RT/PE-Xb compound pipeline complex pipeline, including the composite pipe body of employing three-layer composite structure, institute
Stating composite pipe body and include PE-RT outer layer and PE-Xb layer, described PE-RT external sheath is outside described PE-Xb layer
Side;
It is characterized in that, described composite pipe body also includes that a PE-RT internal layer, described PE-Xb layer are coated on
The outside of PE-RT internal layer.
In a preferred embodiment of the present utility model, in described PE-RT outer layer, PE-Xb layer and PE-RT
The ratio of the thickness of layer is 5: 3: 2.
Compared with prior art, this utility model includes the composite pipe body using three-layer composite structure, and is somebody's turn to do
Composite pipe body includes PE-RT internal layer, PE-Xb layer and PE-RT outer layer, and PE-Xb layer is coated on PE-RT internal layer
Outside, and PE-RT external sheath is in the outside of PE-Xb layer, adopting the structure can be by the side of hot melt
Pipeline is linked together firmly by method with pipe fitting, it is possible to effectively avoid the junction at pipeline Yu pipe fitting
The situation that appearance is leaked, and also do not interfere with the health of domestic water, further increase this multilamellar
The Practical Performance of PE-RT/PE-Xb compound pipeline complex pipeline.
