Abstract: Pressure reduction and conditioning valve for simultaneously reducing the pressure and temperature of steam.

Abstract: A conditioning valve for simultaneously reducing the pressure and temperature of steam. The invention comprises a valve body divided into first and second chambers, the first chamber having an inlet port for the introduction of superheated steam under high pressure into said conditioning valve and the second chamber having an outlet port for expelling desuperheated and depressurized steam out of said conditioning valve; an annular seat affixed to the interior of said valve between said first and second chambers; a hollow cylindrical cage slidably coupled with said seat, said cage permitting the flow of steam between said first and second chambers when said cage is in a first position and preventing said flow of steam when said cage is in a second position; and water stem means coupled to said cage for adjusting said cage between said first and second positions, said stem means having an outlet for injecting desuperheating water into said second chamber to be mixed with said steam.

Abstract: A strainer for preventing debris from entering a turbine. The strainer comprises a casing having an inlet conduit for introducing a flow medium into said strainer and an outlet conduit extending substantially perpendicular to said inlet conduit for expelling said flow medium, said outlet conduit having conically expanding interior side walls; an annular seal affixed to said casing between said inlet and outlet conduits for forming a seal between said inlet and outlet conduits; a bonnet attached to said casing, said bonnet having an upper bonnet section affixed to said casing and hollow cylindrical lower bonnet cage which mates with said annular seat, said hollow cylindrical lower bonnet cage opening into said outlet conduit and having a plurality of apertures so as to permit flow into said hollow cavity and out said outlet conduit and strainer screen means surrounding said hollow cylindrical lower bonnet, said screen means preventing debris from entering said apertures.
