Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0019] refer to Figure 1-2 , large-diameter molded lined PTFE pipeline, including the main pipe body 1, and the two ends of the main pipe body 1 are fixedly sleeved with sealing rings 8 to ensure the sealing of the pipe joints. The inner wall of the main pipe body 1 is coated with anti-corrosion paint. To improve the anti-corrosion ability inside the pipeline, the outer wall of the main pipe body 1 is slidingly sleeved with two symmetrically arranged support plates 2 to protect the outside of the pipeline. The support plate 2 is arc-shaped, and the outer wall is fixed with a wear-resistant sleeve to enhance The wear resistance of the support plate 2;

Abstract

The invention discloses a large-caliber mould pressing lining tetrafluorohydrazine pipeline which comprises a main pipe body. Two symmetrically-arranged supporting plates are in sliding connection tothe outer wall of the main pipe body in a sleeving manner. Sliding rods are fixedly connected to the inner walls of the supporting plates. Sliding cavities corresponding to the sliding rods are arranged on the outer wall of the main pipe body. The sliding rods are sleeved with springs. The two ends of each spring are fixedly connected with the corresponding supporting plate and the outer wall of the main pipe body correspondingly. The two ends of the main pipe body are fixedly connected with connecting flanges in a sleeved manner. Two symmetrically-arranged baffles are arranged at the two endsin the main pipe body, and the baffles are rotationally connected with the inner wall of the main pipe body through rotating shafts. Through the arrangement of a protection mechanism, the pipeline can be effectively protected, and therefore the service life of the pipeline is prolonged.

Description

technical field [0001] The invention relates to the technical field of PTFE pipelines, in particular to large-diameter molded pressure-lined PTFE pipelines. Background technique [0002] PTFE-lined pipes have been widely used in chemical, metallurgy, mining, energy, pharmaceutical and other industries. The traditional PTFE-lined pipes have a simple structure design, which is steel PTFE composite pipes, which can withstand strong acids and alkalis. [0003] However, the existing PTFE-lined pipeline has a relatively simple external structure and lacks a certain protection mechanism outside the pipeline, thereby affecting the service life of the pipeline. Contents of the invention [0004] The purpose of the present invention is to solve the problem that the external structure of the PTFE-lined pipeline is relatively simple in the prior art, and the outside of the pipeline lacks a certain protection mechanism, and the large-diameter molded PTFE-lined pipeline is proposed. ...
