Description

давлени  в полости эластичного цилиндра происходит его раздувание, а также раздувание эластичной покрышки 12. Под воздействием сил упругой деформации происходит перемещение концов эластичного цилиндра со скосами 10, в результате чего открываютс  разгрузочные отверсти  8.the pressure in the cavity of the elastic cylinder is inflated, as well as the inflation of the elastic tire 12. Under the influence of the elastic deformation forces, the ends of the elastic cylinder move with the bevels 10, as a result of which the discharge openings 8 open.

Через эти отверсти  происходит сброс сжатого воздуха в затрубное пространство, давление уравниваетс  и дальнейшее расширение эластичного цилиндра прекращаетс . После прекращени  работы воздух отключаетс  н под вли нием остаточной деформации эластичный цилиндр и покрышка возвращаютс  в первоначальное положение.Through these holes, compressed air is discharged into the annulus, the pressure is equalized and the further expansion of the elastic cylinder is stopped. After the termination of the operation, the air is turned off under the influence of permanent deformation, the elastic cylinder and the tire return to their original position.

Предмет изобретени Subject invention

Устройство дл  герметизации усть  скважины , включающее корпус с уплотнителем буровой штанги и пневматической муфтой в виде эластичного цилиндра дл  уплотнени  усть  скважины, отличающеес  тем, что, с целью повышени  эффективности работы, корпус снабжен двум  втулками с цилиндрическими проточками, образующими с корпусом кольцевые полости, в которых свободно установлен эластичный цилиндр, при этом кольцевые полости сообщены с затрубным пространством при помощи разгрузочных отверстий.A device for sealing a wellhead, comprising a housing with a drill rod seal and a pneumatic clutch in the form of an elastic cylinder for sealing a wellhead, characterized in that, in order to increase work efficiency, the housing is equipped with two bushings with cylindrical grooves forming annular cavities with the housing which freely installed elastic cylinder, while the annular cavity communicated with the annular space by means of discharge openings.
