Outdoor pipeline thermal insulation pipe shell

Abstract

The invention discloses an outdoor pipeline thermal insulation pipe shell. The outdoor pipeline thermal insulation pipe shell comprises a pipe shell body with a hollow cylinder structure, wherein the pipe shell body comprises two half shells; a groove is formed in the outer side end of one end face of each half shell; a convex step is arranged on the outer side end of the other end face of each half shell; platy extension parts are arranged on two end parts of the inner surface of one half shell; the platy radian of each extension part is fitted with the inner surface of the other half shell; toothed stripes used for filling adhesive are arranged on the groove bottom planes of the grooves and the step top planes of the convex steps; locking rings are arranged on the cylindrical external surfaces of the half shells and are connected with rope pieces which are used for fixedly connecting the two half shells. The outdoor pipeline thermal insulation pipe shell has the advantages that the structure is simple, the operation is convenient and the practicability is strong; more thermal energy can be locked and effective thermal insulation is realized; the outward radiation of a thermal source is cut off from one end, where the adjoining face gap of the half shells is in contact with a conveying pipeline, and the optimal thermal insulation effect is realized; the disassembly and assembly are convenient, and the construction efficiency is high.

Description

technical field [0001] The invention relates to an auxiliary part for external use of conveying pipelines, in particular to an outdoor pipeline insulation shell, which belongs to the technical field of pipeline insulation. Background technique [0002] Insulation pipelines are widely used in liquid and gas transportation pipe networks. In insulation transportation pipelines, pipeline insulation is a very important link. The success of this link is directly related to whether the pipeline can be officially put into use. [0003] At present, the general insulation pipeline uses shell insulation. There are two main types of existing thermal insulation shells. One is a circular tube with a fracture along the axial direction. When installing, the thermal insulation shell is opened to wrap the tube for installation; the other is two half tubes. The shell is formed into a round tube. Each joint surface of these structures is a plane, and it is extremely easy to cause gaps at the ...

AI Technical Summary

Problems solved by technology

The joint surfaces of these structures are all flat, and it is extremely easy to cause gaps at the joint surfaces during installation, which directly affects the thermal insulation effect

The structure of these shells inevitably encounters the problem of "thermal bridge", that is to say, the heat radiation radiates outward through the gap between the shells and the shells, resulting in heat loss, thus affecting the insulation effect

[0004] In addition, in the prior art, the insulation tube shell commonly used in the conveying pipeline is composed of two half-tube shells with a certain length. The outer surface of the shell is bound and fixed around the circumference, which not only brings inconvenience to the construction, but also is not conducive to the disassembly and reuse of the heat preservation shell
