DESTRUCTING MECHANISM FOR SOLUBLE SEALING DEVICE Russian patent published in 2020 - IPC E21B29/00 E21B33/12 

FIELD: glass.

SUBSTANCE: invention relates to a crushing mechanism for a soluble sealing device comprising one or more layers of glass. Breaking mechanism comprises a coupling configured to support one or more layers of glass by means of a hydraulic fluid. According to the first embodiment, the destructing mechanism contains a supporting chamber with a hydraulic fluid. Unloading chamber communicates with supporting chamber. Crushing device has the possibility of crushing one or more layers of glass. Glass supporting coupling is made with possibility of axial displacement together with one or more layers of glass, when hydraulic fluid is released from supporting chamber into unloading chamber. According to the second embodiment, the destructing mechanism comprises an axially shifted coupling element configured to open and close a plurality of perforations. Chamber with fluid arranged between glass supporting sleeve and axially shifted by coupling element. Axially displaceable coupling element is configured to move the crushing device diagonally into one or more layers of the glass when the plurality of perforations is not open.

EFFECT: technical result is improved reliability of glass destruction process.
