Since the 20th century, chemical fibers have been produced with the development of polymer materials. The advent of chemical fibers has changed the history of human beings for thousands of years only natural fibers as the only textile fiber raw materials, and has opened up broad prospects for obtaining new and more superior textile fibers. The raw materials of chemical fibers come from oil, natural gas, coal and agricultural and forestry by-products, etc., with the rapid growth of the petroleum industry, the development of the variety, quantity and technical level of synthetic fibers far exceeds the production of man-made fibers. In the production process of the chemical fiber industry, the safety and stability of the pipeline system is the key to production, and the valve products need to be able to cope with the complex situation of the chemical fiber pipeline system, so that the pipeline system in the production process can run more freely.
