Abstract
The utility model relates to the two-tube pipe elbow of a kind of intelligent prefabricated direct-buried thermal insulation pipe working steel tube.At present, the defects such as domestic traditional prefabricated direct-buried thermal insulation pipe ubiquity that heat waste consumption is large, operating cost is high, <b/> carbon emission amount is large, pipeline working life is short.The two-tube pipe elbow of a kind of intelligent prefabricated direct-buried thermal insulation pipe working steel tube; its composition comprises: polyethylene outer protective pipe (1); there is in described polyethylene outer protective pipe protective polyurethane layer (3); described protective polyurethane layer wraps up one group of two-tube working steel tube (4); there is in described protective polyurethane layer alarming line (2), there is between described polyethylene outer protective pipe and two-tube working steel tube supporting bracket plate (5).The utility model is applied to the two-tube pipe elbow of intelligent prefabricated direct-buried thermal insulation pipe working steel tube.
Description
technical field:
the utility model relates to the two-tube pipe elbow of a kind of intelligent prefabricated direct-buried thermal insulation pipe working steel tube.
background technique:
at present, the defect such as domestic traditional prefabricated direct-buried thermal insulation pipe ubiquity that heat waste consumption is large, operating cost is high, discharge amount is large, pipeline working life is short.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 performance loop can be formed.
summary of the invention:
the purpose of this utility model is to provide the two-tube pipe elbow of a kind of intelligent prefabricated direct-buried thermal insulation pipe working steel tube.
above-mentioned object is realized by following technological scheme:
the two-tube pipe elbow of a kind of intelligent prefabricated direct-buried thermal insulation pipe working steel tube; its composition comprises: polyethylene outer protective pipe; in described polyethylene outer protective pipe, there is protective polyurethane layer; described protective polyurethane layer wraps up one group of two-tube working steel tube; in described protective polyurethane layer, there is alarming line, there is between described polyethylene outer protective pipe and two-tube working steel tube supporting bracket plate.
the described two-tube pipe elbow of intelligent prefabricated direct-buried thermal insulation pipe working steel tube, described working steel tube internal diameter is 20-1200mm, and described protective polyurethane layer thickness is 30-200mm, and described outer pillar thickness is 1-30mm.
the beneficial effects of the utility model:
1. can compare with regard to not traditional prefabricated direct-buried thermal insulation pipe in the utility model saving heat loss aspect, two-tubely to work simultaneously, form own circulation and more can effectively reduce cost reduction running cost, reduce 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.
between the utility model polyethylene outer protective pipe and working steel tube, there is supporting bracket; to its intensity of working steel tube and the mutual support reinforcing of polyethylene outer protective pipe; the use more steadily simultaneously decreasing material is installed; in protective polyurethane layer, there is alarming line, when occurring alarm function to be played when leaking.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
accompanying drawing 2 is plan views of the present utility model.
embodiment:
embodiment 1:
the two-tube pipe elbow of a kind of intelligent prefabricated direct-buried thermal insulation pipe working steel tube, its composition comprises: polyethylene outer protective pipe 1, there is in described polyethylene outer protective pipe protective polyurethane layer 3, described protective polyurethane layer wraps up one group of working steel tube 4, there is in described protective polyurethane layer alarming line 2, described polyethylene outer tube has high temperature resin layer, described high temperature resin layer has anticorrosive coat, described anticorrosive coat has watertightness barrier, described polyethylene outer protective pipe and working steel tube have between the ends and are connected supporting bracket plate 5, described polyethylene outer protective pipe top and bottom are plane, upper plane width is less than lower plane width, described alarming line is positioned at plane side.
embodiment 2:
the two-tube pipe elbow of intelligent prefabricated direct-buried thermal insulation pipe working steel tube according to embodiment 1, described working steel tube internal diameter is 20-1200mm, and described protective polyurethane layer thickness is 30-200mm, and described outer pillar thickness is 1-30mm.
