Float Valve Core

In normal well-drilling, the valve cover of the floating valve core opens, then the drilling fluid circulates smoothly. When the well kick or blowout occurs under the well, the valve cover is closed so as to reach the purpose of blowout prevention, which can prevent the drilling fluid backflow, and prevent the sediment from getting into the drill string to get anti -blocking effect during stripping-in operations.
