Abstract
A diverter valve is disclosed and may comprise an actively cooled valve actuation section, an actuator, and a valve section comprising a rotationally actuated valve plate that is structured to be rotationally actuated by the actuator to direct flow wherein the actuation section may be thermally insulated from the valve actuation section.
Claims16
A valve apparatus comprising:
- a) a shaft;
- b) a valve section comprising:
- a ceramic chamber housing;
- a ceramic mat material located externally to the chamber housing;
- a ceramic base adjoining the chamber housing to enclose a chamber;
- a shaft opening located through the chamber housing;
- a thermally insulating seal located between the shaft opening and the chamber housing;
- an inlet port located in the chamber housing;
- outlet ports located in the ceramic base;
- a rotatable ceramic plate located between the chamber housing and the ceramic base having at least one aperture and being rotatable by the shaft in order to move the aperture relative to the output ports and being rotatable by the shaft in order to self clean the rotatable ceramic plate by rotation about the ceramic base;
- and
- c) a valve actuation section comprising:
- at least one biasing device connected to the shaft;
- and
- cooling ports located in the valve actuation section for thermally cooling the valve actuation section and the biasing device.
A hydrogen reformate diverter valve for use with a hydrogen reformer comprising:
- an actively cooled valve actuation section;
- an actuator;
- and
- a valve section comprising a rotationally actuated valve plate that is structured to be rotationally actuated by the actuator to direct hydrogen reformate and wherein the sections are structured to be thermally insulated from each other.
The hydrogen reformate diverter valve of claim 12 wherein the actively cooled valve actuation section includes ports for sending air through the valve actuation section before the air it is sent to an air inlet port of a reformer.
A hydrogen reformate diverter for use with a hydrogen reformer comprising:
- a valve for diverting hydrogen reformate at temperatures up to 900° C. comprising a rotationally actuated valve plate having at least one aperture and wherein said rotationally actuated valve plate is structured to be rotationally actuated by an actuator to direct the hydrogen reformate from an inlet port located in the valve through the aperture to an outlet port located in the valve.
