  • Production tubes for use in the completion of an oil well
    Patent number: 4566541
    Abstract: A connector for incorporation in a production tube for an oil well, below the packer, comprises a closing flap which closes when a first retractable ball seat is displaced downwards, in order to provide a safety device during the installation of the well head, and above the flap, a second retractable ball seat which, when it is moved away axially downwards, causes the flap to open and be maintained in the open position, in order to put the well in a state of production. The balls seats are provided in the upper portions of two resiliently radially expandable sleeves and are displaced downwardly by the application of fluid pressure to the space within the production tube above their other closure of the respective seat by a ball dropped on to the seat from above.
