[0002] In modern industrial production, especially in the fields of semiconductor manufacturing, chemical industry and pharmaceutical industry, there are very high requirements for the corrosion resistance of materials and the purity of fluids. As a kind of thermoplastic plastic with very high chemical stability and thermal stability, PFA (Perfluoroalkoxy) has excellent corrosion resistance and non-adhesion, making it an ideal material for handling corrosive fluids, high-temperature environments and high-purity requirements. PFA plug valves play an important role in these industries due to their unique performance advantages.

[0003] However, the traditional PFA rotary valve is prone to many problems during long-term use, the most important of which is the cleaning work inside the rotary valve. In the cleaning process of traditional rotary valves, clean water is usually directly poured into the interior to assist in cleaning. However, during the cleaning process inside the rotary valve, water is prone to cleaning dead angles, and it can also cause corrosion of the rotary blades. Therefore, most people still clean the rotary blades by disassembling the entire device in the traditional rotary valve cleaning process. However, traditional valve designs often use complex connection structures, such as bolt connections and welding. These connection methods require a lot of time and effort to disassemble and reassemble. Since disassembling and reassembling the valve requires a lot of time, it can cause the production line to be shut down for a longer period of time, thereby reducing production efficiency and affecting the overall use of the device.
