Drill Stem Testing Hydraulic Circulating Valve 5" x 15000 psi
The Hydraulic Circulating Valve is the part of drill stem testing
string, it serves as a bypass around the packer or as a circulating
valve to circulate a well after testing.The Hydraulic circulating
valve’s delay function carried out by special hydraulic oil flow
over the metering
system, when push top coupling moves forward, the mandrel string
and metering system also move forward(Oil chamber divide into 2
parts by metering sleeve), when the fluid in below part flow to top
part caused by pressure added, the circulating ports will be closed
because of delay function of metering sleeve(The flow rate depend
on weight set down, the more weight set, the more flow rate, and
the shorter time delay).
