High-temp plane gate valve

The utility model relates to a high-temperature plane gate valve which is composed of a valve body, a valve seat, a valve cover a valve rod, a gate plate, a drive device, a sealing component and an installing component. The valve seat and the gate plate adopt the metallic sealing. A carbon sealing ring is primarily provided between the radial direction of the valve seat and the valve body, and the carbon seal ring is pressed between the valve seat and the valve body by a pressing ring to realize the sealing between the valve seat and the valve body. A high-temperature spring is provided between the horizontal direction of the valve seat and the valve body, and the components of the utility model contacting with the medium are completely provided with the high temperature material. Thus, the utility model has the advantages of high using temperature, etc. The reliable sealing between the valve seat and the valve body can be obtained through regulating a compression screw in using. The high-temperature plane gate valve is suitable for the high-temperature and high-pressure medium, the corrosive medium, the medium containing the particles, the slurry medium and the operating condition with the pipe cleaning requirement.
