Working principle of plug valve.

The working principle of the plug valve is to realize the opening or closing function by rotating 90 degrees to connect or separate the channel opening on the valve plug with the channel opening on the valve body. The design of this valve makes its structure relatively simple, with fast opening and closing speed, small flow resistance, and easy maintenance. The valve plug of the plug valve can be cylindrical or conical. Such a design not only makes its structure light but also facilitates the cleaning and maintenance of the pipeline. The plug valve uses a plug body with a through hole as the opening and closing part, and the valve stem controls the rotation of the plug body to complete the opening and closing action. This valve is widely used in municipal construction, farmland water conservancy, thermal power generation, petrochemical, metallurgy and mining, fire protection and environmental protection, food, shipping, medicine light textile, and other fields. It is mainly used to control media flow in pipelines and equipment.
