DESTRUCTION MECHANISM FOR A DISOLVABLE SEALING DEVICE

摘要

The present invention relates to a plug (1) comprising a crusher mechanism for a dissolvable sealing device, where the sealing device comprises one or more glass layers (2) positioned in a wellbore. The invention is characterized in that the glass (2) in a barrier phase bears against at least one seat or support sleeve (4) arranged axially displaceably in the wellbore, where the at least one seat or support sleeve (4) bears against the glass (2) by means of a supporting hydraulic fluid (6) found in a pressure support chamber (12), the seat or support sleeve (4) being arranged to be released, be displaced axially and to crush the glass (2) when the supporting hydraulic fluid (6) is released from its pressure support chamber (12).
