Any technology that uses chemical methods to change the composition and structure of substances or synthesize new substances belongs to chemical production technology, that is, chemical process, and the resulting products are called chemicals or chemical products. At first, the production of such products was done by hand workshops, which later evolved into factories and gradually formed a specific production industry, namely the chemical industry. Most chemical plants use rotary joints to connect pipes.

[0003] However, the prior art still has the following problems:

[0004] Firstly, when the high-pressure and high-speed stainless steel rotary joints of the prior art are in use, most of them cannot be rotated when fixed, which causes the pipeline to be easily twisted during installation, thereby causing the pipeline to be easily damaged.

[0005] Secondly, when the high-pressure and high-speed stainless steel rotary joints of the prior art are in use, most of them cannot effectively limit the pipeline, causing the pipeline to loosen easily after connection, thereby causing the gas or liquid inside the pipeline to flow out.

[0006] In view of the above problems, the inventor proposes a high-pressure and high-speed stainless steel rotary joint for the chemical industry to solve the above problems. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The utility model uses a rotating mechanism. After the high-pressure and high-speed stainless steel rotary joint is connected to the pipeline, the pipeline can be rotated to avoid distortion, reducing the loss of the pipeline, thereby realizing that the high-pressure and high-speed stainless steel rotary joint can be rotated while being fixed;

[0012] 2.
