Preferably, polytetrafluoroethylene materials are used for the pipeline main body lining and the corrugated pipe.
By adopting the technical scheme, when hydrochloric acid liquid flows through the pipeline and the corrugated pipe for connecting the pipeline, because polytetrafluoroethylene has stronger corrosion resistance, the condition of leakage is not easy to occur, the safety is improved, and the service lives of the pipeline and the corrugated pipe are greatly prolonged.
Preferably, the corrugated pipe outer layer is sleeved with a corrugated pipe outer layer woven mesh.
By adopting the technical scheme, the corrugated pipe can bear the abrasion and corrosion of the external environment in the use process, and the service life of the corrugated pipe is greatly prolonged.
Preferably, the fixing member is made of metal.
Through adopting above-mentioned technical scheme, the mounting can bear external environment's erosion and wearing and tearing, can play the effect of fixed pipeline better.
Preferably, the fixing member can be changed in inner diameter size by adjusting the fixing member bolt.
By adopting the technical scheme, the fixing piece can be attached to the pipeline without being additionally equipped, and when the position of the fixing piece needs to be adjusted, the inner diameter size of the fixing piece can be enlarged by loosening the bolt of the fixing piece, so that the fixing piece is loosened from the pipeline, and the fixing piece is convenient to adjust.
Preferably, the inner diameter surface of the fixing member is provided with a washer of the inner layer of the fixing member.
Through adopting above-mentioned technical scheme for the mounting can firmly be fixed self on the pipeline main part.
To sum up, the utility model discloses following beneficial effect has: the outer layer of the pipeline main body can resist the abrasion of the external environment, and the hydrochloric acid liquid only contacts the polytetrafluoroethylene of the inner lining of the pipeline main body when flowing through, so that the corrosion and leakage can not occur; the pipelines are connected through the corrugated pipe, the corrugated pipe can be freely bent and stretched, different connection angles required by the pipelines can be conveniently and flexibly adapted, and the outer layer woven mesh of the corrugated pipe can also enable the corrugated pipe to bear the abrasion and erosion of the external environment to a certain extent, so that the service life of the corrugated pipe is prolonged; when hydrochloric acid flows to the corrugated pipe between the two pipelines, the corrugated pipe is firmly and tightly connected with the pipelines through threads, and the corrugated pipe is also made of polytetrafluoroethylene, so that the corrosion and leakage are not easy to occur; after the pipeline is erected, the fixing part bolt on the pipeline is loosened without additionally arranging a fixing part of the pipeline, the fixing part bolt is screwed down after the fixing part bolt is moved to a proper position, the fixing part inner-layer gasket on the inner diameter surface of the fixing part ensures that the fixing part inner-layer gasket can be firmly fixed on a pipeline main body, and a screw penetrates through a fixing part base pin hole to fix the fixing part inner-layer gasket on the wall surface or the ground together with the pipeline.
