A pipe insulation layer structure based on jacket

Abstract

The invention relates to a pipeline heat preservation layer structure based on the outer sleeve type. The structure comprises a heat preservation sleeve body, a bending pipe is arranged in the heat preservation sleeve body, the top end of the bending pipe is in abut joint with a vertical pipe, the right end of the bending pipe is in abut joint with a transverse pipe, the top end of the heat preservation sleeve body covers the bottom end of the vertical pipe, the right end of the heat preservation sleeve body covers the left end of the transverse pipe, heat preservation structures are arrangedon the two ends of the heat preservation sleeve body, and are arranged on the abut-joint positions of the transverse pipe and the bending pipe, seal mechanisms are arranged between the heat preservation sleeve body and the left end of the transverse pipe and between the heat preservation sleeve body and the bottom end of the vertical pipe, each seal mechanism comprises a seal annular shell, the seal annular shells are arranged on the periphery of the left end of the transverse pipe and the periphery of the bottom end of the vertical pipe, arc guide grooves are formed in the inner sides of theseal annular shells, an arc guide rod is arranged at the end of the heat preservation sleeve body, and the arc guide rod is arranged in the arc guide grooves. Exterior air can be prevented from entering the abut-joint position of a pipeline, the temperature of media in the pipeline is ensured, the subsequent production machining process is ensured, and the falling risk of the seal mechanisms can be removed.

Description

technical field [0001] The invention relates to the technical field of pipeline insulation layers, in particular to a jacket-based pipeline insulation layer structure. Background technique [0002] In the process of industrial production, it is often necessary to use pipelines to transport fluids, especially for the transportation of fluids between various devices in refining and chemical enterprises. Most of these fluids need to be transported with insulation to ensure that the internal medium can maintain a constant temperature in each process. This requires insulation of the pipes. [0003] One of the ways to insulate pipes is to put insulation sleeves around the pipes. However, there are the following problems when the current insulation sleeve is connected to the pipeline: 1. The sealing effect between the end of the insulation sleeve and the pipeline is poor, and the cold air from the outside will also enter the joint of the pipeline, which will affect the temperature...

Problems solved by technology

However, there are the following problems when the current insulation sleeve is connected to the pipeline: 1. The sealing effect between the end of the insulation sleeve and the pipeline is poor, and the cold air from the outside will also enter the joint of the pipeline, which will affect the temperature of the medium inside the pipeline , affecting the subsequent production and processing technology; 2. When connecting the sealing mechanism, there is a small connection between the sealing mechanism and the insulation sleeve, and there is a risk of the sealing mechanism falling off
