ABSTRACT:
A steam and fuel oil control and purge valve has a body which defines generally radial steam and oil inlet and discharge ports, in top-to-bottom order coaxial generally cylindrical steam discharge and inlet chambers and oil discharge and inlet chambers, and three coaxial smaller cylindrical openings in top-to-bottom order respectively between the steam discharge and inlet chamber, the steam inlet and oil discharge chamber, and the oil discharge and inlet chambers. A cylindrical steam valve and actuator is slidable in the opening between the steam inlet and oil discharge chambers and has axially spaced upper and lower radial openings and an internal interconnecting axial passageway. In its closed position, a seating surface at an upper end of the valve and actuator closes the upper cylindrical opening between the steam discharge and inlet chambers and the lower radial opening in the valve and actuator is closed by the wall of the intermediate cylindrical opening in the valve body. In a partially open purge position, the upper and lower valve and actuator openings communicate respectively with the steam inlet and oil discharge chambers to steam purge the fuel oil line. In a fully open position, the steam inlet and discharge chambers communicate through the upper cylindrical opening, the upper radial valve opening is closed by the wall of the intermediate cylindrical opening in the valve body to terminate communication between the steam inlet and oil discharge chambers, and an axially projecting actuating pin on the valve and actuator opens a coaxial poppet-type oil valve to connect the oil inlet and discharge chambers.
