[0002] An elbow, as the name implies, is a component used in a pipeline system to achieve pipeline bending or direction change. It enables the fluid to smoothly turn in the pipeline system while maintaining the tightness and stability of the system. Elbows are widely used in various pipeline systems, including water supply and drainage systems, HVAC systems, industrial fluid transportation systems, etc. Due to the flow of the fluids used, the pipelines are generally made of polytetrafluoroethylene material to improve the corrosion resistance of the pipelines and extend their service life. However, there are still the following defects:
[0003] Since the elbow is used in a liquid flow system, when the elbow is not in use, moisture will adhere to the surface of the elbow. If the pipeline is in contact with moisture for a long time, the corrosion resistance effect of the pipeline will be affected, shortening the service life of the pipeline. Summary of the Utility Model
[0004] In view of the above situation, to overcome the defects of the prior art, the utility model provides a corrosion-resistant polytetrafluoroethylene elbow structure, effectively solving the problem that the elbow is in contact with moisture for a long time, affecting the corrosion resistance effect of the pipeline.

A spring 2033 is fixedly installed at the bottom end of the movable block 2031, and the bottom end of the spring 2033 is fixedly connected to the fixing ring 2032. The top wall of the movable block 2031 is in close contact with the inner top wall of the top cylinder 201. A first magnetic block 2036 is installed at the top end of the movable block 2031.

[0027] The auxiliary gate unit 204 includes a gate box 2041 fixedly installed on the connecting pipe 202. The gate box 2041 is communicated with the connecting pipe 202.
