Plug valve is a valve used to control the flow of fluids. It is widely used in chemical, petroleum, natural gas and other industries, and is particularly suitable for the switching and regulation of fluid flow. Its main feature is to control the flow of fluids by rotating a plug-like component.
###Purpose of plug valve:
1. Product flow control and switching: Plug valves are often used in pipeline systems, especially in situations where fluid flow needs to be quickly opened or closed.
2. High temperature and high pressure environment: Plug valves can be used in some high temperature and high pressure environments to adapt to more extreme working conditions.
3. Control of corrosive or viscous fluids: Due to the good sealing performance of plug valves, it is widely used to control viscous or corrosive fluids, such as oil and gas, acid and alkali liquids, etc.
4. Large flow pipelines: Plug valves are suitable for the switching control of large flow and large diameter pipelines, especially when the flow of fluids does not require too much regulation.
5. Low flow regulation: Plug valves are also suitable for applications where flow regulation is relatively simple.
6. Isolation and switching of gas and liquid: In equipment that needs to frequently switch the flow path of gas or liquid, the plug valve can quickly switch the direction of the fluid.
