Abstract
The invention relates to a telescopic connector repairing sleeve of a prefabricated direct-embedded heat preservation pipeline system and a connecting method. Welding of an original connector repairing plate is realized in a way that electricity is supplied to the outer parts of two ends of the original connector repairing plate for carrying out hot melting after the original connector repairing plate is rolled, the bundling of the original connector repairing plate is firm and integrated hot melting welding is achieved from the surface, but an outer protection pipe of a pipeline cannot be in contact with a thermal fuse due to low temperature of the outer protection pipe, the outer protection pipe cannot be melted, the original connector repairing plate is only adhered to the surface of the outer protection pipe after being melted, and the integration of the outer protection pipe and the connector repairing plate never can be realized. The telescopic connector repairing sleeve of the prefabricated direct-embedded heat preservation pipeline system comprises a pipe body (1), wherein the pipe body is in a dumbbell shape, the middle pipe diameter of the pipe body is the same as the diameter of the outer protection pipe of a heat preservation pipeline, the pipe diameter of two ends of the pipe body is greater than the diameter of the outer protection pipe of the heat preservation pipeline, and the two ends of the pipe body are provided with telescopic pipes (2). The telescopic connector repairing sleeve and the connecting method, disclosed by the invention, are applied to the telescopic connector repairing sleeve of the prefabricated direct-embedded heat preservation pipeline system.
Description
technical field:
the present invention relates to a kind of prefabricated direct-buried thermal insulation pipe road system scalability repaired mouth sleeve pipe and connecting means.
background technique:
in prefabricated direct-buried thermal insulation pipe more than 30 years since the eighties introduces China, improve the thermal efficiency of Chinese central heat supply, saved mass energy.But along with a large amount of application, need construct at the scene in the attachment portion of pipe joint part, due to reasons such as the engineering time is urgent, natural temperature coolings, cause pipeline after steel-pipe welding, the outer pillar sweat soldering quality of thermal insulation pipe cannot promote, cause pipe joint place heat insulation effect low, outer pillar not prison welding infiltration is the main cause causing pipe temperature to decline.The welding of original repaired mouth plate be after repaired mouth coiled sheet bag at two ends additional electric heating melting, surface is seen and is tied up firmly, sweat soldering reaches one, but because the outer pillar temperature of pipeline is low, do not reach thermo-fuse, can not melt, just repaired mouth plate is pasted onto outer pillar surface after dissolving, outer pillar and repaired mouth plate is caused to realize one never, along with the variation of temperature, the extruding of soil, the position be pasted not strongly just there will be gap and breaks, and soil moisture enters into thermal insulation layer immediately, causes heat insulation effect to decline to a great extent.
summary of the invention:
the object of this invention is to provide a kind of prefabricated direct-buried thermal insulation pipe road system scalability repaired mouth sleeve pipe and connecting means.
above-mentioned object is realized by following technological scheme:
a kind of prefabricated direct-buried thermal insulation pipe road system scalability repaired mouth sleeve pipe, its composition comprises: body, described tubular form is for being dumbbell-like shape, in the middle of described body, caliber is identical with the outer pillar diameter of insulation pipe, described body two ends caliber is greater than the outer pillar diameter of insulation pipe, and described body two ends are telescopic tube.
described prefabricated direct-buried thermal insulation pipe road system scalability repaired mouth sleeve pipe, described body material polyethylene.
the connecting means of described prefabricated direct-buried thermal insulation pipe road system scalability repaired mouth sleeve pipe, first be the scalable repaired mouth sleeve pipe of caliber standard according to the outer pillar diameter of different size insulation pipe, material is consistent with outer pillar, and scalable repaired mouth sleeve pipe two ends diameter is slightly soft and be greater than outer pillar external diameter; Before two prefabricated direct-buried thermal insulation pipe welding, outside scalable repaired mouth casing pipe sleeve wherein an outer pillar, after steel-pipe welding ne-leakage, scalable repaired mouth sleeve pipe is moved to two outer pillar repaired mouth positions, remove the dust foreign material on outer pillar, use radio frequency heating wind welding machine, blow to repaired mouth sleeve pipe two ends, after two ends are heated, natural shrinking fusing combines together with outer pillar, realize seamless outer pillar to connect, soil moisture cannot infiltrate the thermal insulation layer in pipe, thus serves high-efficiency insulated function.
beneficial effect of the present invention:
1. the present invention due to repaired mouth sleeve pipe two ends be contractility, after repaired mouth position is determined, while adopting the outer pillar of hot blast welding machine fusing, repaired mouth sleeve pipe heat shrinkable melts, be welded together with the outer pillar surface of fusing, form seamless integrated polyethylene and connect, the change of temperature and soil, the polyethylene of one all can not be made to form phase transformation be separated, thus realize the high quality repaired mouth heat insulation effect of NBS requirement.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present invention.
accompanying drawing 2 is sectional views of the present invention.
