REDUCED TORQUE VALVE COVER LOCK ASSEMBLY

摘要

A valve cover lock assembly for a pump having a fluid end module can include a ring adapted to couple to the module, an insert comprising a plurality of segments, and a cone adapted to couple with the insert, wherein the ring comprises a first coupler and the insert comprises a second coupler configured to couple with the first coupler, wherein the cone is configured to move one or more of the plurality of segments when the cone is moved, and wherein the first and second couplers are adapted to at least partially resist movement of the insert. A method of locking a valve cover can include coupling a ring to a valve cover opening, disposing an insert comprising a plurality of segments at least partially within the ring, coupling an actuator to the insert, and coupling the insert to the ring.

1. A valve cover lock assembly for a pump having a fluid end module with a valve cover opening, the valve cover lock assembly comprising:
a ring having an opening there through and an interior wall, wherein the ring is adapted to couple to the module so that the opening through the ring is in fluid communication with the valve cover opening; an insert having an opening there through and comprising a plurality of segments that collectively form an interior wall and an exterior wall of the insert, the insert being disposed at least partially within the opening through the ring; a cone having an opening there through and an exterior wall, the cone being disposed at least partially within the opening through the insert; and a cone nut disposed at least partially within the opening through the cone, the cone nut having a first end adapted to couple with a valve cover; wherein the interior wall of the ring comprises a first coupler and the exterior wall of the insert comprises a second coupler configured to couple with the first coupler; wherein the cone is configured to move the plurality of segments radially outwardly when the cone is moved in a first direction relative to the insert until the first and second couplers are coupled; and wherein the first and second couplers are adapted to at least partially resist axial movement of the insert relative to the ring when the first and second couplers are coupled.
