Single Ram Blowout Preventer

FZ single-gate blowout preventer is a key part of the well control device and plays a vital role in drilling, well repair, oil testing and other operations.Working principle: When high-pressure oil enters the closing chamber of the oil cylinder, it pushes the piston and piston rod to move the gate assembly toward the center of the wellhead along the track defined by the guide ribs in the gate chamber to achieve the purpose of sealing the well; when high-pressure oil enters the opening chamber of the oil cylinder, the gate assembly moves away from the center of the wellhead, thereby opening the wellhead, and the direction of opening and closing of the gate is controlled by the reversing valve.Structural features: The pressure-bearing parts are made of high-quality alloy steel with good strength and impact toughness. The side door seal of the high-pressure blowout preventer adopts a combined sealing ring with strong well pressure sealing ability. Floating or integral gates are used, whic…
