Technical Field

[0001] This utility model relates to the field of blowout preventers, and in particular to a flange-connected double-gate manual blowout preventer. Background Technology

[0002] Blowout preventers (BOPs) are used to close the wellhead during operations such as well testing, well workover, and well completion to prevent blowout accidents. They combine the functions of full sealing and partial sealing into one unit and are characterized by simple structure, easy operation, and high pressure resistance. They are commonly used safety sealing devices for preventing blowouts in oilfields.

[0003] The existing blowout preventer has a simple structure and cannot selectively replace its internal gate according to usage requirements, resulting in a limited range of applications and inconvenient subsequent maintenance.

[0004] Therefore, it is necessary to propose a flange-connected double-gate manual blowout preventer to solve the above problems. Utility Model Content
