High-strength casing pipe convenient to fix and used for refrigeration pipeline

Abstract

The invention provides a high-strength casing pipe convenient to fix and used for a refrigeration pipeline. The high-strength casing pipe comprises a hollow pipe body, the pipe body comprises a firstend and a second end which are opposite, the first end is integrally connected with an annular fixed limiting plate, the fixed limiting plate communicates with the pipe body, and the second end is integrally connected with an annular reinforcing rib. The pipe body of the high-strength casing pipe is integrally formed, so that the casing pipe is high in structural strength and not prone to being deformed, a steel pipe can be effectively protected and prevented from being extruded and deformed, and the space between the pipeline and the casing pipe is filled with an elastic net sleeve, so that the steel pipe and the pipe body are closely matched, and vibration or abnormal noise is avoided accordingly; and the casing pipe can be fixed to a wall by the fixed limiting plate, so that the situation that the casing pipe shakes due to being not tightly embedded in the wall is avoided, and fixing firmness is improved.

Description

technical field [0001] The invention relates to the technical field of refrigerating equipment, in particular to a high-strength sleeve for a refrigerating pipeline that is convenient for fixing. Background technique [0002] Refrigeration equipment refers to equipment mainly used for food refrigeration, refrigeration of various goods and indoor air conditioning in summer. It is mainly composed of compressor, expansion valve, evaporator, condenser, accessories and pipelines. During the layout and installation of refrigeration equipment, various parts are mainly connected through different pipelines to ensure the flow of refrigerant. Most of the refrigeration pipes of the refrigeration equipment are steel pipes. When the steel pipes pass through the wall, a part of the wall usually needs to be protected by a sleeve to prevent the steel pipe from being squeezed and deformed. The casing in the prior art is usually rolled and welded by iron sheet, the pipe wall is relatively t...

AI Technical Summary

Problems solved by technology

The casing in the prior art is usually rolled and welded by iron sheet, the pipe wall is relatively thin, and there are welds, which makes the casing easily deformed. At the same time, due to the deformation of the casing or the protruding weld, the steel pipe and The sleeves cannot be tightly fitted and the refrigeration pipes are squeezed, which may cause unnecessary vibration or abnormal noise of the pipes

In addition, in the prior art, after the casing passes through the wall, foam glue is usually filled between the casing and the wall to fix it. After a long time, the foam glue will age and fall off, making the casing loose in the through hole in the wall. , as the equipment vibrates, the refrigeration pipeline will cause vibration or abnormal noise
