Conical rubber core annular blowout preventer

According to the structure of the rubber core, the drilling annular blowout preventer is divided into spherical and conical.

The spherical rubber core annular blowout preventer has the characteristics of simple structure, convenient disassembly and firm sealing.

The conical rubber core annular blowout preventer has only the piston and the conical rubber core as moving parts, which effectively reduces the wear area of the cone core and prolongs the service life of the rubber core.
