Claims14
A valve and tool assembly, comprising:
- a valve comprising a longitudinal axis and a valve seat recess,
- a valve seat, and
- a valve seat extraction tool that is attachable to said valve by an eccentric alignment member;
- wherein the eccentric alignment member is adapted to be assembled with the valve to eccentrically align the valve seat extraction tool with the valve seat, wherein said eccentric alignment member has an alignment axis that is parallel to and radially offset from a centerline of the valve seat when the valve seat extraction tool is mounted to the valve body.
A valve seat extraction tool assembly comprising a valve seat extraction tool having a threaded portion, and an eccentric alignment member that is adapted to be mounted to a valve body to align said threaded portion eccentrically with a valve seat, wherein said eccentric alignment member has an alignment axis that is parallel to and radially offset from a centerline of the valve seat when the valve seat extraction tool is mounted to the valve body.
A valve seat extraction tool assembly comprising a valve seat extraction tool having a threaded portion, and an eccentric alignment member that is adapted to be mounted to a valve body to align said threaded portion eccentrically with a valve seat, wherein said eccentric alignment member comprises a retainer nut threadably adapted to be threadably mated with the valve body, the retainer nut comprises an internal bore having a central axis that is parallel to and radially offset from a center line of the retainer nut.
