Patent ID: 11332999

Abstract:
A plug assembly arranged in a housing including: a plug, a breaker object, a seat, a shear ring and a snap ring. The plug is supported by the seat and the shear ring prevents the seat from moving in an axial direction. The shear ring is arranged such that when a threshold pressure differential is applied to a surface of the plug, the shear ring hears and allows for axial movement of the seat. The plug assembly has a first position, a second position, and a third position. In the first position, the plug is not in contact with the breaker object, in the second position, the shear ring has sheared and the plug is in contact with the breaker object causing the plug to break, and in the third position, occurring during or after the plug makes contact with the breaker object, the snap ring is arranged to lock the seat into place to prevent the seat from moving axially.
