Patent ID: 11345005

Abstract:
The invention is an improved tool for pulling a valve seat from a valve in a fluid end. The invention replaces the standard threaded nut and stem commonly used in such tools with a split nut comprising a plurality of removeably engageable split nut segments placed within a base and a stem configured to be used with the plurality of removeably engageable split nut segments. In the preferred embodiment, each split nut segment possesses a center-facing surface relative to the longitudinal axis of the invention comprising a set of horizontal v-grooves suitable to be disposed against complementary v-grooves of the stem. The base permits the plurality of split nut segments to be placed in an engaged position permitting the v-grooves of the split nut segments to removeably engage the v-grooves of the stem securely or to be placed in a disengaged position. The base containing the split nut segments is durable enough to be used in oil field work but lightweight enough to be used by individual or groups of workers safely.
