The utility model discloses a kind of suction rubber of
blowout preventer box, it relates to
petroleum exploitation technical field, specifically a kind of suction rubber of
blowout preventer box, including two matrix, framework, the upper end opening inner
diameter of matrix is greater than lower end opening inner
diameter, the matrix is constituted by straight cylinder section, conical cylinder section, anti-jamming section, the upper and lower ends of straight cylinder section are respectively fixedly connected with conical cylinder section, anti-jamming section;By adopting two matrix, two matrix are constituted after being spliced by jointing a cylinder structure.In the replacement of suction rubber of
blowout preventer box, it is not necessary to disassemble or move
sucker rod, just replace two matrix in blowout preventer box, two matrix are constituted after being spliced by jointing a cylinder structure, the cylinder structure can embrace the outer lateral wall of
sucker rod all around, greatly improve the disassembly replacement efficiency of suction rubber, avoid affecting project progress.
