The FUV type fire buried (telescopic rod) elastic seat sealing gate valve group adopts a design scheme that can be maintenance free and extend the valve stem. It is buried in one go, avoiding the expensive cost of the valve well and the huge investment caused by multiple road renovations and valve replacements. It beautifies the road environment, is resistant to rolling, and avoids accidents caused by the loss of the well cover. The valve stem can be extended and retracted freely according to the valve well. The top of the valve stem is equipped with a valve switch display, and a signal remote transmission device and a valve misoperation locking device can be installed.
