Abstract
The invention relates to a thermal insulation pipe fitting elbow with a leakage point monitoring function. Since an abroad prefabricated buried thermal insulation pipe fitting has been introduced into China in 80s, only the prefabricated buried thermal insulation pipe fitting can be produced up to now even after many years, and a pipe fitting leakage point detecting and monitoring technology which is matched and integrated with the prefabricated buried thermal insulation pipe fitting is not grasped up to now. The thermal insulation pipe fitting elbow with the leakage point monitoring function comprises an elbow working tube (4), wherein the inner surface of the elbow working tube is coated with a corrosion-resistant coating (7); the outer surface of the elbow working tube is coated with a heat-insulation corrosion-resistant coating (8); the outside of the heat-insulation corrosion-resistant coating is packaged with a polyurethane thermal insulation layer (3); a polyethylene outer protective tube (2) is arranged outside the polyurethane thermal insulation layer; an alarm line (1) is arranged in the polyurethane thermal insulation layer; the alarm line is connected with an alarm (5) through a signal line; the alarm is connected with a monitoring center (6) through the signal line; and a vertical section of the elbow working tube is subjected to circular-arc transition. The thermal insulation pipe fitting elbow is applied to monitoring a pipe fitting elbow with a leakage point.
Description
technical field:
