Abstract
It is two-tube that the utility model relates to a kind of prefabricated direct-buried thermal insulation pipe working steel tube.The defects such as current domestic traditional prefabricated direct-buried thermal insulation pipe ubiquity that heat waste consumption is large, operating cost is high, carbon emission amount is large, pipeline working life is short, to ensureing the feature of environmental protection of city cold and heat supply, energy saving, Economy and Security limited use.The utility model method comprises: the outer pillar (1) of polyvinyl plastics, be connected with polyurethane insulation coating (2) in the outer pillar of described polyvinyl plastics, be provided with heat supply pipeline steel pipe (3) and return steel pipe (4) in described polyurethane insulation coating, described heat supply pipeline steel pipe and described return steel pipe are all provided with alarming line (5) outward.The utility model is used for city cold and heat supply pipeline.
Description
technical field:
it is two-tube that the utility model relates to a kind of prefabricated direct-buried thermal insulation pipe working steel tube.
background technique:
at present, it is large that domestic traditional prefabricated direct-buried thermal insulation pipe ubiquity heat waste consumption, operating cost is high, carbon emission amount is large, the defect such as pipeline working life is short, the traditional type prefabricated direct-buried thermal insulation pipe of domestic use is all that the form of the outer pillar of employing one steel pipe one carries out Cemented filling, another pipeline formation loop must be set up can use while work, when cable laying operation, excavate a zanjon, width will reserve working width and machinery and to pass through width, if lay two pipelines simultaneously, wider ditch will be excavated, ensure the weld job space of pipeline, cause road excavation wide, stemming operation amount is large, Engineering Overall cost is too high, to the feature of environmental protection ensureing city cold and heat supply, energy saving, Economy and Security limited use.
summary of the invention:
it is two-tube that the purpose of this utility model is to provide a kind of prefabricated direct-buried thermal insulation pipe working steel tube.
above-mentioned object is realized by following technological scheme:
a kind of prefabricated direct-buried thermal insulation pipe working steel tube is two-tube, its composition comprises: the outer pillar of polyvinyl plastics, be connected with polyurethane insulation coating in the outer pillar of described polyvinyl plastics, heat supply pipeline steel pipe and return steel pipe are installed in described polyurethane insulation coating, described heat supply pipeline steel pipe and described return steel pipe are all provided with alarming line outward, make prefabricated direct-buried two-tube thermal insulation pipe possess intelligent alarm effect.
the beneficial effects of the utility model:
1. the utility model avoids some unnecessary economic waste and energy wastes of conventional pipelines, make the groove simultaneously excavating two thermal insulation pipes, change into and only excavate a groove, the confession of pipeline, return two pipelines simultaneously in a thermal insulation pipe, while heat insulation effect is constant, greatly reduce road excavation width, decrease road to take, unimpeded urban transportation, improve engineering construction progress, save the engineering road cost of 50%, make the feature of environmental protection of guarantee city cold and heat supply, energy saving, Economy and Security effect perform to the ultimate attainment of current world-technology.
the utility model adopts two steel pipe to foam and same outer pillar protection simultaneously, enter you and greatly reduce heat loss, effectively reduce user cost and decrease carbon emission amount, fully demonstrate the two-tube process engineering of prefabricated direct-buried thermal insulation pipe working steel tube not only energy saving but also economic environmental protection, more fully can ensure that working life of prefabricated direct-buried thermal insulation pipe, traditional type prefabricated direct-buried thermal insulation pipe is all that the form of the outer pillar of employing one steel pipe one carries out Cemented filling, another pipeline formation loop must be set up can use while work, but the two-tube process engineering of prefabricated direct-buried thermal insulation pipe working steel tube just effectively avoids the foundation of this primary Ioops, because be equipped with two isometrical steel pipes in an outer pillar, effectively can form performance loop, two-tube thermal insulation pipe system, two-tube elbow can be configured equally, threeway, spanning tee, the tubing products such as reducing, make two-tube thermal insulation pipe product more perfect and call oneself system, in two-tube thermal insulation pipe system, alarm system can be added, prefabricated direct-buried two-tube thermal insulation pipe is made to have possessed intelligent alarm effect, can find timely and effectively and the position of targeted duct breakage, real realizes the prefabricated direct-buried two-tube thermal insulation pipe system integration technology product of perfect intelligence.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
