Self-cold-insulation compensator for low-temperature pipeline

Abstract

The invention discloses a self-cold-insulation compensator for a low-temperature pipeline. The self-cold-insulation compensator comprises a shell and a connecting mechanism, wherein the connecting mechanism is arranged on the shell, and the connecting mechanism comprises an inlet end connecting pipe, two PIR cold insulation assemblies, a first cold insulation sleeve, an inner-layer corrugated pipe, a stay rod assembly, an outer-layer corrugated pipe, an electric heat tracing assembly, a second cold insulation sleeve and an outlet end connecting pipe. According to the self-cold-insulation compensator for the low-temperature pipeline, through mutual cooperation of the shell, the inlet end connecting pipe, the PIR cold insulation assemblies, the first cold insulation sleeve, the inner-layer corrugated pipe, the stay rod assembly, the outer-layer corrugated pipe, the electric heat tracing assembly, the second cold insulation sleeve, the outlet end connecting pipe, pipe connecting flanges, a vacuumizing opening, an electric heat tracing connector, a pressure gauge connector and a standby opening, the self-cold-insulation compensator for the low-temperature pipeline is achieved; and on the premise of ensuring that the compensator can be used under the designed working conditions, the cold loss amount of the pipeline can be effectively reduced, the service life of the compensator is prolonged, and therefore the practicability is improved; and great convenience is brought to a user.

Description

technical field [0001] The invention relates to the technical field of self-cold-insulation compensators, in particular to a self-cold-insulation compensator for low-temperature pipelines. Background technique [0002] Self-cooling compensators are usually used in low-temperature pipelines, but common self-cooling compensators cannot effectively reduce the cooling loss of pipelines, and long-term use is likely to affect the service life of the compensator, which greatly reduces the practicability. It brings great inconvenience to users, so we provide a self-insulated compensator for low-temperature pipelines. Contents of the invention [0003] The object of the present invention is to provide a self-cooling compensator for low temperature pipelines, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a self-insulated compensator for...
