The working principle of a full bore plug valve is to control the flow of fluid by rotating the plug body. The plug body is usually cylindrical or conical in shape, with channels arranged on top. When the plug body is in contact with the valve body channel, the fluid can pass smoothly; When the two are misaligned, the fluid is blocked. This design endows the plug valve with the ability to respond quickly to fluid control, enabling it to flexibly respond to various flow control and diversion requirements under different working conditions. ‌
The structural characteristics of full bore plug valves:
The core structure of a full bore plug valve includes a rotatable conical plug (plug) and a valve body. This type of valve has many advantages due to its unique structure, such as easy operation, low fluid resistance, rapid opening and closing, as well as simplified components and lightweight.
Application scenarios of full bore plug valves:
Full bore plug valves are often used in situations where it is necessary to cut off or connect media, distribute or change the flow direction of media, and can also be used for throttling regulation. Due to its fast opening and closing characteristics, full bore plug valves are particularly suitable for handling pipelines and equipment containing corrosive media. In addition, small unfilled plug valves are also known as "cocks", and their plug bodies are mostly conical (or cylindrical), which cooperate with the conical hole surface of the valve body to form a seal.
