Description
Technical field:
The present invention relates to a kind of prefabricated direct-buried plastic, thermal-insulation pipes and manufacturing method for capableing of flexible coil pipe.
Background technique:
The actual life of prefabricated direct-buried plastic, thermal-insulation pipe currently on the market is unable to satisfy the design requirement of 30-50, main
The Trinity structure for meeting pipeline can not be sent out because of plastic, thermal-insulation pipe, expanded with heat and contract with cold and easily caused the de- of outer protection tube and polyurethane
It falls, aliquation.
The ununified intelligent alarm system of current prefabricated direct-buried plastic, thermal-insulation pipe, can not predict the reality of utilidor
Operating condition, the ability more repaired in advance without preliminary examination, can not timeliness discovery leak source, there is prefabricated direct-buried plastic, thermal-insulation pipes
The risk of booster, and then the serious accident that happens suddenly.
At present insulating tube due to structure it is harder, the length for being able to carry out coil pipe is small, cause the connector in specific length more,
It is easy to appear leakage problem.
Summary of the invention:
The object of the present invention is to provide a kind of prefabricated direct-buried plastic, thermal-insulation pipes and manufacturing method for capableing of flexible coil pipe.
Above-mentioned purpose is realized by following technical scheme:
A kind of prefabricated direct-buried plastic, thermal-insulation pipe for capableing of flexible coil pipe, composition includes: instrumentation tubes, the work tube outer surface
With soft bubble layer of polyurethane, the soft bubble layer of polyurethane is connect by glue-line with outer protection tube, in the soft bubble layer of polyurethane
2 alarming lines are installed, are corrugated outside the outer protection tube.
The prefabricated direct-buried plastic, thermal-insulation pipe for capableing of flexible coil pipe, the outer protection tube is PE outer protection tube.
A kind of manufacturer using the prefabricated direct-buried plastic, thermal-insulation pipe for capableing of flexible coil pipe described in one of claim 1-2
Method,
Uncoiler by instrumentation tubes uncoiling, unreel；
Instrumentation tubes are corrected instrumentation tubes, traction device provides pulling force for instrumentation tubes, and temperature control equipment is to work by means for correcting
Make pipe and carry out temperature control, guarantees 35-40 degrees Celsius of optimum temperature when foaming；
Adhering device provides a contact adhesive layer before foaming for foaming mould, can improve polyurethane and the bonding force of PE, moreover it is possible to rise
To the purpose of mold releasability；
Intelligent alarm line is installed；
Mold foaming, high-presure polyurethane foaming machine will be injected into polyurethane blowing mold after urethane raw high pressure mixing, real
Existing polyurethane mould is continuous foamed；
The plasticizing of PE particle is extruded into PE outer protection tube, is existed using the method for vacuum suction by the molding of PE outer protection tube, single screw extrusion machine
Polyurethane surface forms PE outer protection tube；
Dragger provides pulling force for molding insulating tube；
Cutting machine cuts pipeline according to the length of design；
The insulating tube that manufacture is completed is coiled radius according to design and coiled by winder, then bundlees, completes the system of insulating tube
It makes.
The utility model has the advantages that
The present invention is corrugated by the polyurethane insulation coating of prefabricated direct-buried plastic, thermal-insulation pipe and the design of PE outer protection tube, greatly reduces
The coiling radius of insulating tube can also produce random length so that the joint length of insulating tube greatly prolongs according to the demand of user
The customization pipeline of size.
The present invention reduces the usage quantity of repaired mouth since the length of single pipe is extended, and reduces pipeline laying
Meteorological, reduces the risk of leakage, and substantially increases the security performance of pipe network.
The present invention is since intelligent prefabricated direct buried plastic, thermal-insulation pipe is in PE outer protection tube layer and protective polyurethane layer medium design
One layer of glue-line, substantially increases the overall performance of insulating tube, has been truly realized the Trinity structure of insulating tube, and guarantor improves pre-
The service life of direct-buried thermal insulation pipe processed.
The present invention devises intelligent alarm line in the polyurethane insulation coating of prefabricated direct-buried thermal insulation pipe, and pipe network may be implemented
Intelligent monitoring, realize foresight maintenance, greatly reduce the risk of pipe burst, avoid the generation of great burst accident.
Flexible coil pipe may be implemented in the prefabricated direct-buried plastic, thermal-insulation pipe of the present invention, and single pipe length is up to hundred meters of even public affairs
In, it greatly reduced repaired mouth, reduce the construction cost of pipeline.Due to the reduction of repaired mouth quantity, prefabricated direct-buried thermal insulation pipe
Risk of leakage also decreases.
