Robust Quick-Connection Mechanism For Use With Valve Actuator Assemblies and Linearly Actuated Valves and Related Methods

摘要

Apparatus and methods for connecting a linear actuating mechanism of an actuator to a valve stem of a linearly actuated valve, are provided. An example of an apparatus can include an elongate valve stem member of a valve, an extension member of a linear actuating mechanism, a locking cap member, and a locking member insertable into the locking cap member for locking the valve stem member with the extension member through employment of the locking cap member.

主权项

1. An apparatus for connecting a linear actuating mechanism of an actuator to a valve stem of a linearly actuated valve, the apparatus comprising:
a segmented locking member comprising a plurality of engagement members each including an inner surface profile configured to complement an outer surface profile extending along an outer surface portion of an outer surface of a valve stem member of a valve to lockingly engage therewith, and a tapered outer surface profile configured to engage inner surface portions of a tapered recess extending into an extension member of a linear actuating mechanism when urged therealong; and a locking cap member configured to contain the segmented locking member, to receive distal end portions of the valve stem member, to receive portions of the extension member, and to urge the plurality of engagement members into slidable engagement with the inner surface portions of the tapered recess extending into the extension member and into locking engagement with the grooved outer surface profile extending along the outer surface portion of the outer surface of the valve stem member, during coupling of the locking cap member with the extension member.
