The rust removing device in the present embodiment is applicable to rust removal of a pipe, for example, the following pipe is provided in the present embodiment, and the rust removing device in the present embodiment can be used to perform rust removal of the following pipe.

A pipeline comprises a first pipeline, a second pipeline arranged opposite to the first pipeline, and a pipeline connecting mechanism used for connecting the first pipeline and the second pipeline. The first pipeline and the second pipeline are any two parts of the pipeline, in practice, the pipe diameters of the first pipeline and the second pipeline can be set to be the same or different, and the pipe diameters of the first pipeline and the second pipeline in the embodiment are the same.

The pipeline connecting mechanism is used for connecting the first pipeline and the second pipeline so as to overcome the problem that the first pipeline and the second pipeline are cracked due to expansion with heat and contraction with cold in the using process.

The pipeline connecting mechanism comprises a third pipeline, a first corrugated pipe, a transition flange plate, a second corrugated pipe and a clamping sleeve, wherein the first corrugated pipe, the transition flange plate, the second corrugated pipe and the clamping sleeve are sleeved on the third pipeline; wherein the cutting ferrule is preferably made of copper with good plasticity. The third pipeline is communicated with the first pipeline and the second pipeline, wherein the flange end of the third pipeline is fixedly connected with the flange end of the first pipeline, the pipeline end part of the third pipeline extends into the second pipeline, and the outer diameter of the pipeline end of the third pipeline is smaller than the inner diameter of the second pipeline. The first corrugated pipe, the transition flange plate, the second corrugated pipe and the clamping sleeve are arranged on the outer side of the third pipeline.

The first corrugated pipe is fixedly connected with the flange end of the third pipeline, and the other end of the first corrugated pipe is fixedly connected with the first end of the transition flange plate; one end of the second corrugated pipe is fixedly connected with the flange end of the second pipeline, and the other end of the second corrugated pipe is fixedly connected with the second end of the transition flange plate. The inner hole of the second end of the transition flange plate is a tapered hole; the clamping sleeve is sleeved at the position, between the second corrugated pipe and the third pipeline, of the pipeline end on the third pipeline, and the taper of the clamping sleeve is equal to that of the tapered hole in the transition flange plate.

The first corrugated pipe, the transition flange plate, the second corrugated pipe and the second pipeline are communicated with each other. When the first pipeline, the third pipeline and the second pipeline are communicated with each other and convey media (liquid or gas materials), the media can enter the first corrugated pipe through the second corrugated pipe and the tapered holes in the transition flange plate, and whether the media can enter the transition flange plate and the first corrugated pipe is realized by the tapered holes in the transition flange plate and the clamping sleeve. This is because the cutting ferrule of this embodiment specifically cup joints on the pipeline end of third pipeline, when the cutting ferrule laminating was on the bell mouth of transition ring flange, just realized the effect of closing to the passageway.

Through the arrangement of the structure, when the pipeline connecting mechanism is communicated with the first pipeline and the second pipeline, the expansion deformation of the first pipeline and the second pipeline when the first pipeline and the second pipeline are expanded with heat and contracted with cold is solved by utilizing the elasticity of the first corrugated pipe. Therefore, when the first corrugated pipe is arranged, the corrugations of the first corrugated pipe are arranged in a plurality of ways to offset the amount of expansion and contraction deformation generated when the first pipeline and the second pipeline are expanded with heat and contracted with cold.

The ripple of the second corrugated pipe is preferably set to be one, and the ripple on the second corrugated pipe is arranged in a protruding mode relative to the third pipeline, so that accumulated liquid is prevented from being formed on the ripple wall of the second corrugated pipe when the pipeline connecting mechanism is used for communicating the first pipeline and the second pipeline and participating in medium conveying. Furthermore, the second end of the transition flange plate is fixedly connected with the second corrugated pipe and the flange end of the second pipeline, and is specifically realized by the long bolt, and the first corrugated pipe and the second corrugated pipe can stretch back and forth, so that people can drive the long bolt to realize the fitting of the tapered hole on the transition flange plate and the tapered end surface on the clamping sleeve by stretching the transition flange plate when adjusting, and a channel for allowing a medium in the second pipeline to enter the first corrugated pipe is cut off, so that the first pipeline and the third pipeline do not need to be stopped when the first corrugated pipe is cracked.
