Drilling ram blowout preventer

The main pressure bearing components of the drilling ram blowout preventer, such as the shell and side door, are cast from high-strength and high toughness alloy steel and subjected to appropriate heat treatment. Before leaving the factory, conduct a water pressure strength test according to the standard to ensure safe and reliable use under working pressure; The drilling gate blowout preventer has high support bars and a sand settling slope inclined towards the wellbore, which can automatically remove mud and sand when the gate is opened and closed, reduce the frictional resistance of the gate movement, and also facilitate the sealing effect of well pressure on the gate; The drilling ram blowout preventer adopts a floating ram seal, which can reduce the resistance of the ram opening and closing, reduce the wear of the rubber core, extend the service life of the ram, and prevent the shell and ram from rusting together, making it easy to disassemble; The hydraulic oil circuit of the drilling ram blowout preventer adopts a buried structure to avoid damaging the oil passage during installation, transportation, and use.
