Abstract
It is capable of the prefabricated direct-buried plastic, thermal-insulation pipe of flexible coil pipe.The ununified intelligent alarm system of current prefabricated direct-buried plastic, thermal-insulation pipe, can not predict the actual operating mode of utilidor, the ability more repaired in advance without preliminary examination, can not timeliness discovery leak source, there is the risks of prefabricated direct-buried plastic, thermal-insulation pipe booster, and then the serious accident that happens suddenly.The utility model composition includes: instrumentation tubes (1), the work tube outer surface has soft bubble layer of polyurethane (2), the soft bubble layer of polyurethane is connect by glue-line with outer protection tube (3), 2 alarming lines (4) are installed in the soft bubble layer of polyurethane, are corrugated outside the outer protection tube.The utility model is used for prefabricated direct-buried plastic, thermal-insulation pipe.
Description
Technical field:
The utility model relates to a kind of prefabricated direct-buried plastic, thermal-insulation pipes for capableing of flexible coil pipe.
Background technique:
The design that the actual life of prefabricated direct-buried plastic, thermal-insulation pipe currently on the market is unable to satisfy 30-50 is wanted
It asks, the Trinity structure for meeting pipeline can not be sent out by being primarily due to plastic, thermal-insulation pipe, expanded with heat and contract with cold and easily caused outer protection tube and poly- ammonia
The falling off of ester, 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.
Utility model content:
The purpose of the utility model is to provide a kind of prefabricated direct-buried plastic, thermal-insulation pipes 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, outside the instrumentation tubes
Surface has soft bubble layer of polyurethane, and the soft bubble layer of polyurethane is connect by glue-line with outer protection tube, the soft bubble polyurethane
2 alarming lines are installed in layer, 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.
The utility model has the advantages that
The utility model is corrugated by the polyurethane insulation coating of prefabricated direct-buried plastic, thermal-insulation pipe and the design of PE outer protection tube, greatly
The coiling radius for reducing insulating tube greatly can also produce according to the demand of user so that the joint length of insulating tube greatly prolongs
The customization pipeline of random length size.
The utility model reduces the usage quantity of repaired mouth, reduces pipeline paving since the length of single pipe is extended
If a Meteorological, reduce the risk of leakage, and substantially increase the security performance of pipe network.
The utility model is set among PE outer protection tube layer and protective polyurethane layer due to intelligent prefabricated direct buried plastic, thermal-insulation pipe
One layer of glue-line has been counted, the overall performance of insulating tube is substantially increased, has been truly realized the Trinity structure of insulating tube, has protected and improves
Service life of prefabricated direct-buried thermal insulation pipe.
The utility model devises intelligent alarm line in the polyurethane insulation coating of prefabricated direct-buried thermal insulation pipe, and pipe may be implemented
The intelligent monitoring of net realizes foresight maintenance, greatly reduces the risk of pipe burst, avoid the hair of great burst accident
It is raw.
The prefabricated direct-buried plastic, thermal-insulation pipe of the utility model may be implemented flexible coil pipe, single pipe length up to hundred meters even
It one kilometer, greatly reduced repaired mouth, reduce the construction cost of pipeline.Due to the reduction of repaired mouth quantity, prefabricated direct-buried heat preservation
The risk of leakage of pipe also decreases.
Detailed description of the invention:
Attached drawing 1 is the structural schematic diagram of the utility model.
Attached drawing 2 is the sectional view of the utility model.
Specific embodiment:
Embodiment 1:
A kind of prefabricated direct-buried plastic, thermal-insulation pipe for capableing of flexible coil pipe, composition includes: instrumentation tubes 1, the instrumentation tubes
Outer surface has soft bubble layer of polyurethane 2, and the soft bubble layer of polyurethane is connect by glue-line with outer protection tube 3, and the soft bubble is poly-
2 alarming lines 4 are installed in urethane layer, are corrugated outside the outer protection tube.
The thermal coefficient of prefabricated direct-buried plastic, thermal-insulation pipe can be stable control at 0.027W/ (mK), and polyurethane density
Uniformly.
Embodiment 2:
According to the prefabricated direct-buried plastic, thermal-insulation pipe described in embodiment 1 for capableing of flexible coil pipe, the outer protection tube is outside PE
Pillar.
The prefabricated direct-buried plastic, thermal-insulation pipe for capableing of flexible coil pipe can greatly prolong the joint length of pipeline, reduce repaired mouth
Quantity reduces the input cost that pipeline is laid with.
It can accomplish few connector even zero connector for special user, greatly improve the leakage of prefabricated direct-buried thermal insulation pipe
Risk improves the total quality of pipe network.
Since intelligent prefabricated direct buried plastic, thermal-insulation pipe is in PE outer protection tube layer and one layer of glue of protective polyurethane layer medium design
Layer, substantially increases the overall performance of insulating tube, has been truly realized the Trinity structure of insulating tube, and guarantor improves prefabricated direct-buried
The service life of insulating tube.
Embodiment 3:
According to the prefabricated direct-buried plastic, thermal-insulation pipe described in embodiment 1 for capableing of flexible coil pipe, manufacturing method:
Uncoiler by instrumentation tubes uncoiling, unreel；
Instrumentation tubes are corrected instrumentation tubes, traction device provides pulling force, temperature control equipment for instrumentation tubes by means for correcting
Temperature control is carried out to instrumentation tubes, 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, also
The purpose of mold releasability can be played；
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
In, realize that polyurethane mould is continuous foamed；
The plasticizing of PE particle is extruded into PE outer protection tube, utilizes the side of vacuum suction by the molding of PE outer protection tube, single screw extrusion machine
Method forms PE outer protection tube in polyurethane surface；
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 insulating tube
Manufacture.
