Abstract

See full text

A pressure relief valve including a housing having an inlet and a relief outlet connected by a fluid flow passageway, the inlet fluidly connectable to a work string. The pressure relief valve includes a head sealingly disposed within the passageway between the inlet and relief outlet closing the fluid flow passageway between the inlet and relief outlet. An elongate buckling rod supports the head and is bucklable at a predetermined load thereby permitting sliding of the head from between the inlet and a relief outlet and opening the fluid flow passageway. A projection within the housing is extendible to an extended configuration, wherein in the extended configuration the projection applies a lateral force perpendicular to the longitudinal direction of the buckling rod bending the rod from its axial center thereby decreasing the load at which the buckling rod collapses.
