Abstract
A flow control valve 30 between a geothermal wellhead and a steam separator 22 is responsive to fluid pressure flowing through the wellhead to the separator and varies the flow rate to the separator 22 in response to the pressure to equalize the flow to the separator 22. A Y-type expansion spool 14 on the wellhead has a pair of auxiliary inlets 76, 78. One of the auxiliary inlets 76 has an auxiliary hanger 88 therein to suspend flexible tubing 94 for the injection of chemicals into the well and the other auxiliary inlet 78 provides an entrance 122 for taking a steam sample and permitting a tool to be inserted within the well.
