MECHANICALLY ACTUATED TRAVELING VALVE

摘要

A mechanically actuated traveling valve for use in fluid pumping equipment. More particularly, a multiple component mechanically actuated traveling plug valve having a valve seat, a valve plug and at least one displaceable valve ring positioned therebetween is provided for use in subsurface positive displacement pumps capable of pumping high viscosity fluids, with any gas to liquid ratio, operating at any inclination angle.

主权项

1. A mechanically actuated traveling valve having a housing forming a fluid chamber, the valve comprising:
a reciprocating valve stem having a first end and a second end, and having an outer periphery; valve stem reciprocating means connected to the stem by a valve connector for imparting reciprocating movement from the reciprocating means to the stem; a valve seat secured within the housing, the seat having an inner periphery, the inner periphery of the seat and the outer periphery of the stem defining a first fluid flow area; a valve plug connected to the stem at its second end, the plug having an outer periphery, the outer periphery and the housing defining a second fluid flow area; and at least one displaceable valve ring having an internal and external diameter, the internal diameter of the ring and the outer periphery of the stem defining a third fluid flow area, and the external diameter of the ring and the housing defining a fourth fluid flow area; wherein the first fluid flow area is substantially equal to the second fluid flow area, and substantially equal to the sum of the third and fourth fluid flow areas; and wherein the reciprocating movement of the stem opens and closes the valve.
