Background
The plug valve is a rotary valve in the shape of a closing member or a plunger, and is opened or closed by rotating 90 degrees to make a passage port on the plug communicate with or separate from a passage port on the valve body. In a cylindrical valve plug, the passageway is generally rectangular; whereas in a tapered plug the passage is trapezoidal. These shapes make the construction of the plug valve lightweight. The invention is most suitable for use as a medium for switching off and on and for shunting, but may also be used for throttling, depending on the nature of the application and the erosion resistance of the sealing surfaces. The plug valve is a fast-switching straight-through valve, which can be used for medium with suspended particles because the movement between rotary sealing surfaces has a wiping action and can completely prevent the contact with flowing medium when the valve is fully opened.
The plug valve is mainly used for the circulation of liquid in a pipeline, the common plug valve used for petroleum pipelines on the market at present has the defect of relatively complex link structure, and on the other hand, the air tightness at the pipeline joint is not stable enough, so that the phenomenon of petroleum leakage can be caused.
