    Internal blowout preventer

    A downhole safety valve is a high-pressure drop, one-way valve. The valve's conical plug reduces the erosive action of the mud on the valve seat, ensuring proper closure. Connected to the drill string, the downhole safety valve protects the swivel, hose, and riser. It can also be used upstream of high-pressure pumps to prevent high-pressure well blowouts. A dedicated release tool keeps the valve in the open position, allowing reverse flow. The release tool is pre-installed in the valve as a component, ready for installation on the drilling rig. When the first blowout signal appears from the well, the safety valve can be quickly installed on the drill string.
