Abstract
The utility model relates to the two-tube reduced three-way pipe fitting of a kind of intelligent crosslinked polyethylene thermal insulation pipe.Domesticly be applied to heat supply at present, the prefabricated direct-buried thermal insulation pipe in cooling field do not have intelligent apparatus, cause the breakage of pipeline can not Timeliness coverage and removing the dangerous condition, cause the leakage of mass energy, energy consumption be risen, and disposal of pollutants improves.The two-tube reduced three-way pipe fitting of a kind of intelligent crosslinked polyethylene thermal insulation pipe, its composition comprises: polyethylene outer protective pipe (1), there is in polyethylene outer protective pipe protective polyurethane layer (3), protective polyurethane layer wraps up one group of crosslinked polyethylene working pipe (4), there is in protective polyurethane layer alarming line (2), alarming line is pasted onto in crosslinked polyethylene working pipe by mighty bond, there is between crosslinked polyethylene working pipe and polyethylene outer protective pipe support (5), the diameter of vertical section polyethylene outer protective pipe is greater than or less than horizontal segment polyethylene outer protective pipe diameter.The utility model is applied to the two-tube reduced three-way pipe fitting of intelligent crosslinked polyethylene thermal insulation pipe.
Description
technical field:
the utility model relates to the two-tube reduced three-way pipe fitting of a kind of intelligent crosslinked polyethylene thermal insulation pipe.
background technique:
domesticly be applied to heat supply at present, the prefabricated direct-buried thermal insulation pipe in cooling field do not have intelligent apparatus, in the two-tube reduced three-way pipe fitting of thermal insulation pipe taking crosslinked polyethylene as service pipe, intelligent apparatus is not had yet, cause the breakage of pipeline can not Timeliness coverage and removing the dangerous condition, cause the leakage of mass energy, energy consumption is risen, and disposal of pollutants improves.
summary of the invention:
the purpose of this utility model is to provide the two-tube reduced three-way pipe fitting of a kind of intelligent crosslinked polyethylene thermal insulation pipe.
above-mentioned object is realized by following technological scheme:
the two-tube reduced three-way pipe fitting of a kind of intelligent crosslinked polyethylene thermal insulation pipe; 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 crosslinked polyethylene working pipe; in described protective polyurethane layer, there is alarming line; described alarming line is pasted onto in crosslinked polyethylene working pipe by mighty bond; have support between described crosslinked polyethylene working pipe and polyethylene outer protective pipe, the diameter of vertical section polyethylene outer protective pipe is greater than or less than horizontal segment polyethylene outer protective pipe diameter.
the described two-tube reduced three-way pipe fitting of intelligent crosslinked polyethylene thermal insulation pipe, described crosslinked polyethylene working pipe internal diameter is 20-1200mm, and described protective polyurethane layer thickness is 30-200mm, and described outer protective polyethylene tube thickness is 1-30mm.
the beneficial effects of the utility model:
1. the utility model is two-tube works 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.
the utility model is provided with support between crosslinked polyethylene working pipe and polyethylene outer protective pipe; in foaming process, ensure that crosslinked polyethylene working pipe and polyethylene outer protective pipe can not be subjected to displacement; ensure with one heart; in protective polyurethane layer, there is alarming line, when occurring alarm function to be played when leaking.
