Abstract
The utility model relates to a heat preservation pipe elbow with control leak source function. China through more than 30 years, can only produce prefabricated direct -burried heat preservation pipe so far since the external prefabricated direct -burried heat preservation pipe of the introduction eighties, the pipe fitting leakage point measuring control technology who matches integratively with prefabricated direct -burried heat preservation pipe does not then grasp so far. A heat preservation pipe elbow with control leak source function which constitutes and includes: elbow work pipe (4), elbow work pipe inner surface coating anticorrosion coating (7), elbow work outside of tubes surface coating has thermal -insulated anticorrosion coating (8), thermal -insulated anticorrosion coating outside parcel has polyurethane insulation layer (3), polyethylene outer pillar (2) have outside the polyurethane insulation layer, the polyurethane insulation in situ has alarming line (1), alarming line passing signal line is connected with alarm (5), alarm passing signal line is connected with surveillance center (6), the vertical section department of elbow work pipe is excessive through the circular arc. The utility model discloses use control leak source pipe fitting elbow.
Description
Technical field:
This utility model relates to a kind of heat-insulating pipe fitting elbow with monitoring leak source function.
Background technology:
China is since the prefabricated direct-buried thermal insulation pipe part of the Introduced From Abroad eighties, through more than 30 years, so far prefabricated direct-buried thermal insulation pipe part can only be produced, the pipe fitting leakage point detection monitoring technology of the one that matches with prefabricated direct-buried thermal insulation pipe part is not then grasped so far, every year because pipe burst leakage accident is countless, cause all kinds of causality loss inestimable.
Summary of the invention:
The purpose of this utility model is to provide a kind of heat-insulating pipe fitting elbow with monitoring leak source function.
Above-mentioned purpose is realized by following technical scheme:
A kind of heat-insulating pipe fitting elbow with monitoring leak source function, its composition includes: elbow instrumentation tubes, described elbow instrumentation tubes inner surface coating corrosion-inhibiting coating, described elbow instrumentation tubes outer surface has heat insulating and corrosion coating, it is enclosed with polyurethane insulation coating outside described heat insulating and corrosion coating, outside described polyurethane insulation coating, there is polyethylene outer protective pipe, in described polyurethane insulation coating, there is alarming line, described alarming line is connected with alarm by holding wire, described alarm is connected with Surveillance center by holding wire, the vertical section place of described elbow instrumentation tubes is excessive by circular arc.
The described heat-insulating pipe fitting elbow with monitoring leak source function; the caliber of described elbow instrumentation tubes is 15mm-2000mm; described protective polyurethane layer thickness is 30-200mm, and described outer protective polyethylene tube thickness is 1-30mm, and described holding wire adopts metallic conduction bare wire.
The beneficial effects of the utility model:
1. this utility model has the heat-insulating pipe fitting of monitoring leak source function, it is simply that will solve prefabricated direct-buried thermal insulation pipe part owing to not detecting the function of leak source.Reach prefabricated direct-buried thermal insulation pipe net in underground laying uses, it is possible to detect from inside pipe fitting and outside infringement of leaking, and give in time and feedback leak source signal and warning, it is to avoid large-area tube bursting and leakage accident.
The moisture content leakage that this utility model cannot will detect in heat-insulating pipe fitting, adopt the detection supervising device installed in heat-insulating pipe fitting, can carry out timely detecting and find monitoring, and alarm signal and positional information can be sent at central control room, remind and safeguard and repairing, stop the tube bursting and leakage accident of big flow.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is schematic cross-section of the present utility model.
