Heat insulation pipe joint structure

Abstract

The invention discloses a heat insulation pipe joint structure and relates to the technical field of pipe joints, and the heat insulation pipe joint structure can be used for solving the problems that the existing heat insulation pipe joint is poor in heat insulation effect, unreliable in structure and the like. According to the heat insulation pipe joint structure provided by the invention, a sealing sleeve ring is sleeved at the periphery of a heat insulation sleeve; sealing pieces are arranged between two ends of the sealing sleeve ring and the conventional section of a heat insulation pipe; the two sealing pieces are respectively positioned on two sides of the heat insulation sleeve, so that secondary heat insulation is formed at a butted part of the heat insulation pipe due to the sealing pieces, and the sealing and heat insulation effects are good. The joint part of the heat insulation pipe is arranged on a supporting seat, so that the reliability of the joint part of the heat insulation pipe is guaranteed; a semicircular slot is formed in the supporting seat; a clamping hoop is also arranged on the supporting seat; the joint part of the heat insulation pipe is fixedly arranged on the supporting seat by virtue of the clamping hoop; the clamping hoop can limit the radial motion of the joint of the heat insulation pipe; the joint of the heat insulation pipe can do axial micro motion in a containing space formed between the clamping hoop and the semicircular slot, so that the mounting reliability of the joint of the heat insulation pipe is guaranteed.

Description

technical field [0001] The invention relates to the technical field of pipe joints, in particular to a heat insulating pipe joint structure. Background technique [0002] In the fields of heating, cooling, oil and gas pipeline transportation, etc., in order to ensure the heat insulation of the medium in the pipeline, it is necessary to insulate the pipeline. The usual way to deal with insulated pipelines is to process the required insulated pipelines according to the length first, then install them on site, and form joints at the joints of two sections of insulated pipelines. In the insulation pipe network, the quality of the pipe joints and the quality of the insulation treatment will have a great impact on the use of the entire insulation pipe network. [0003] The existing treatment method is to put a heat-insulating sleeve on the outside of the joint of the pipeline, and perform heat-insulation treatment on the joint through the heat-insulating sleeve. This method canno...

AI Technical Summary

Problems solved by technology

[0003] The existing treatment method is to put a thermal insulation sleeve on the outside of the joint of the pipeline, and conduct heat insulation treatment on the joint through the thermal insulation sleeve. This method cannot guarantee the sealing effect and seriously affects the use of the thermal insulation pipe network.

[0004] In addition, the reliability of the pipe joints is poor. When the pipes vibrate, it is easy to cause the pipe joints to fall off, resulting in the leakage of the medium
