摘要

The invention relates to a well bore control apparatus, system and method for sealing a well bore. The invention relates to a well bore control apparatus comprising a housing having a guide element defining a path, the housing defining a throughbore for receiving a tubular, a first tapered gate and a tapered second gate located within the housing, the first and second gates being adapted to engage with the guide element. In use the first and second gates are moveable along the path defined by the guide element in a direction substantially transverse to the throughbore between an open position of the throughbore and a closed position of the throughbore. The well bore control apparatus comprises a first seal seat for forming a first seal with the first gate in the closed position to seal the throughbore. The well bore control apparatus may include a second seal seat. The second seal seat may be adapted for forming a second seal with the second gate in the closed position to seal the throughbore.
