Problems solved by technology
[0003] Existing insulation pipes are mostly connected by flanges, and the connection position is not equipped with insulation structure, so that the medium passing through the insulation pipe loses more heat at the connection position of the pipeline, and the heat preservation effect is poor. In addition, the flange at the connection position of the pipeline is passed through multiple bolts Only the connection can ensure the stability. The installation of multiple bolts is time-consuming and labor-intensive, and the work efficiency is low.

specific Embodiment approach
[0033] Specific embodiments: the first pipeline 11 is wrapped with the first insulation layer 12 to insulate the first pipeline 11, and the fifth insulation layer 43 is wrapped on the outer surface of the second pipeline 41 to insulate the second pipeline 41. The ring 33 is set on the outside of the second pipe 41, and the support ring 34 can be clamped on the upper part of the second outer convex ring 44 to facilitate the positioning and installation of the collar 33 and the second pipe 41, and then insert the intubation tube 15 into the slot 45, At this time, the lower end of the first outer convex ring 14 on the upper end of the second pipeline 41 is attached to realize the preliminary positioning and installation of the pipeline, and then the first clamping rod 32 is inserted into the collar 33 through the first round hole, and the second clamping rod 35 is passed through the first circular hole. The two through holes are penetrated into the collar 33, and then the fixing r...

The invention relates to the technical field of pipes, in particular to a heat-insulating metal pipe, including a collar, a second pipe, a cannula, a first convex ring, a first clamping rod, a second clamping rod, a collar and a fixing ring , put the collar on the outside of the second pipe, then insert the cannula into the slot, insert the first lever and the second lever from the outside of the collar into the inside of the collar, and then put the fixing ring on the collar , use the fixed ring to limit the first clamping rod and the second clamping rod, realize the upper limit of the first outer convex ring and the lower limit of the second outer convex ring, and realize the connection of the first pipe and the second pipe In addition, the fixing mechanism is connected with the fixing ring and the collar to ensure the stable connection between the fixing ring and the collar. The design of the fixing mechanism is convenient to connect with the fixing parts near the pipeline, which greatly reduces the required bolts and improves the installation. efficiency.
Description
technical field [0001] The invention is a thermal insulation metal pipeline, which belongs to the technical field of pipelines. Background technique [0002] Insulation pipe is the abbreviation of heat insulation pipe. It is used for the transportation of liquid, gas and other media, and it is used in the heat insulation and heat preservation projects of petroleum, chemical industry, aerospace, military, central heating, central air conditioning, municipal and other pipelines. [0003] Existing insulation pipes are mostly connected by flanges, and the connection position is not equipped with insulation structure, so that the medium passing through the insulation pipe loses more heat at the connection position of the pipeline, and the heat preservation effect is poor. In addition, the flange at the connection position of the pipeline is passed through multiple bolts Stability can only be ensured by connection, and the installation of multiple bolts is time-consuming and labor...
