Steel-in-steel steam thermal insulation pipe

Abstract

The invention discloses a steel-in-steel steam thermal insulation pipe. The steel-in-steel steam thermal insulation pipe comprises an outer cylinder and an inner cylinder; the inner cylinder is inserted into the outer cylinder; sleeve frames of concentric circle structures are symmetrically arranged at the positions, located at the two ends of the outer cylinder, between the outer cylinder and the inner cylinder; the outer cylinder is fixedly connected with the inner cylinder through the sleeve frames; three linkage type adjusters are evenly arranged between the outer cylinder and the inner cylinder; the ends of the adjusters are connected with the sleeve frames; rotary supporting mechanisms are installed at the positions, corresponding to the adjusters, of the outer wall of the inner cylinder at equal intervals; three fastening mechanisms are installed in the middle of the outer cylinder at equal intervals; and the fastening mechanisms are connected with the inner cylinder. According to the steel-in-steel steam thermal insulation pipe, through linkage adjustment of the adjusters, the supporting mechanisms rotate so as to form multi-point supporting with the inner wall of the outer cylinder and cooperate with the fastening mechanisms to uniformly pull and position the middle part of the inner cylinder, so that the supporting strength of the middle part of a gap between the outer cylinder and the inner cylinder is improved, and the deformation resistance strength of a device is improved.

Description

technical field [0001] The invention relates to the technical field of steam pipes, in particular to a steel jacketed steel steam insulation pipe. Background technique [0002] With the continuous improvement of heating equipment, the laying of heating equipment has greatly increased. Steam pipelines in heating equipment are relatively common components, which play a role in the sealing and transportation of steam, and use heat preservation methods to reduce heat loss. [0003] The current steam pipelines basically use double-layer steel pipes interspersed, but only the insulation layer is filled in the pipeline cracks of the current steam pipelines. For pipelines with long spans, the middle part lacks the structure, and the resistance to deformation is low. To this end, we propose a steel jacketed steel steam insulation pipe. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a steel jacketed steel steam thermal insulation pipe with high...

Problems solved by technology

[0003] The current steam pipelines are basically interspersed with double-layer steel pipes, but the cracks of the current steam pipelines are only filled with insulation layers. For long-span pipelines, there is no structure in the middle, and the deformation resistance is low.
