Mechanism with simplified handling for controlling a device for sealingly connecting two enclosed spaces

Device for sealingly connecting two enclosed areas, comprising on the first space a first flange delimiting a first opening and a first door closing off said first opening, on the second space comprising a second flange delimiting a second opening and a second door closing off said second opening, the second door being secured to the second flange via a bayonet connection with the first door comprising an annular part providing the sealed contact with the first flange and with the second door and a casing, with the casing and the annular part delimiting with the second door a sealed space, said control mechanism mounted in the annular part, and a control mechanism comprising said control mechanism comprising,

• a male element configured to cooperate with a female element carried by the second door via a bayonet connection,
• means for driving in rotation said male element, said male element being translatably movable along the longitudinal axis and rotatably movable about the longitudinal axis in relation to the annular part, in such a way as to allow for the connection between the two spaces according to at least the following phases:
• a first phase of rotation for searching for the docking position of the male element on the female element, during which the male element is rotated with respect to the annular part,
• a second phase of translation during which the male element docks with the female element and during which the male element is translated with respect to the annular part,
• a third phase of rotation in order to provide the axial locking of the two doors,
• a fourth phase of rotation in order to provide the unlocking of the second door in relation to the second flange.

Method for sealingly connecting a first and a second enclosed space by means of a control mechanism, with the first space comprising a first flange delimiting a first opening and a first door closing off said first opening, with the second space comprising a second flange delimiting a second opening and a second door closing off said second opening, the second door being secured to the second flange via a bayonet connection, with the first door comprising an annular part providing the sealed contact with the first flange and with the second door and a casing, with the casing and the annular part delimiting with the second door a sealed space, said control mechanism mounted in the annular part, said control mechanism comprising:

• a male element configured to cooperate with a female element carried by the second door via a bayonet connection,
• means for driving in rotation said male element, said male element being translatably movable along the longitudinal axis and rotatably movable about the longitudinal axis in relation to the annular part, in such a way as to allow for the connection between the two spaces according to at least the following phases:
• a first phase of rotation for searching for the docking position of the male element on the female element, during which the male element is rotated with respect to the annular part,
• a second phase of translation during which the male element docks with the female element and during which the male element is translated with respect to the annular part,
• a third phase of rotation in order to provide the axial locking of the two doors,
• a fourth phase of rotation in order to provide the unlocking of the second door in relation to the second flange,
• Said method comprising the steps:
• a) putting into contact the first flange and the second flange
• b) putting into rotation of the male element until it penetrates by translation into the recess of the second door,
• c) putting into rotation of the male element in such a way as to axially lock the first and the second door,
• d) putting into rotation of the male element in such a way as to unlock the second door of the second flange,
• e) withdrawing the unit formed by the first and second doors.
