Lug design in the butterfly valve mainly plays a connecting and fixing role. Specifically, lugs (also known as flanges or flanged connection sections) are structures on butterfly valves that are used to connect with other components in the piping system, such as flanges at both ends of the pipe. They are usually located on either side of the butterfly valve and are shaped like protruding rings or ears that are used to align with the holes of the pipe flanges and are held together tightly by bolts or other fasteners.
This design ensures tightness and stability between the butterfly valve and the piping system. With lug connections, the butterfly valve can be securely mounted on the pipe, preventing media leaks and allowing the valve to be easily removed and replaced if needed. In addition, the lug design provides sufficient strength and rigidity to withstand the effects of pressure, temperature and medium flow in the piping system, ensuring the normal operation and long-term use of the butterfly valve.
Therefore, lug design is an integral part of the butterfly valve and has an important impact on the performance and reliability of the butterfly valve.
