Abstract

See full text

An adjustable release pressure relief valve including a housing having an inlet and a relief outlet connected by a fluid flow passageway, the inlet fluidly connectible to a work string. A head is 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 lateral support projection is extendable within the housing to buttress the buckling rod along the longitudinal length of the buckling rod thereby increasing the load at which the buckling rod is collapsible.
