Abstract
The utility model relates to a kind of prefabricated direct-buried thermal insulation pipe road system scalability repaired mouth sleeve pipe.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, and causes outer pillar and repaired mouth plate to realize one never.A kind of prefabricated direct-buried thermal insulation pipe road system scalability repaired mouth sleeve pipe, its composition comprises: body (1), 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 (2).The utility model is applied to prefabricated direct-buried thermal insulation pipe road system scalability repaired mouth sleeve pipe.
Description
technical field:
the utility model relates to a kind of prefabricated direct-buried thermal insulation pipe road system scalability repaired mouth sleeve pipe.
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 purpose of this utility model is to provide a kind of prefabricated direct-buried thermal insulation pipe road system scalability repaired mouth sleeve pipe.
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 beneficial effects of the utility model:
1. the utility model 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.
the scalable repaired mouth sleeve pipe that the utility model is is caliber standard with 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.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
accompanying drawing 2 is the utility model sectional views.
embodiment:
embodiment 1:
a kind of prefabricated direct-buried thermal insulation pipe road system scalability repaired mouth sleeve pipe, its composition comprises: body 1, 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 2.
embodiment 2:
prefabricated direct-buried thermal insulation pipe road system scalability repaired mouth sleeve pipe according to embodiment 1, described body material polyethylene.
Claims (2)
1. a prefabricated direct-buried thermal insulation pipe road system scalability repaired mouth sleeve pipe, its composition comprises: body, it is characterized in that: 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.
2. prefabricated direct-buried thermal insulation pipe road according to claim 1 system scalability repaired mouth sleeve pipe, is characterized in that: described body material polyethylene.
