Abstract
An aspect includes a globe butterfly valve that includes a valve inlet, a valve outlet, a globe housing with a spherical body between the valve inlet and the valve outlet, and a globe butterfly valve disc operably disposed within the globe housing. The globe housing has a larger interior diameter than an inlet diameter of the valve inlet and an outlet diameter of the valve outlet. The globe butterfly valve disc is configured to block a flow path between the valve inlet and the valve outlet responsive to an outer edge of the globe butterfly valve disc being positioned proximate to an interior surface of the globe housing between the valve inlet and the valve outlet.
Claims20
A gas turbine engine system comprising:
- a gas turbine engine comprising a compressor section, a combustor section, and a turbine section, the gas turbine engine configured to produce a first airflow and a second airflow:
- a first pneumatic tube coupled to the gas turbine engine;
- a second pneumatic tube coupled to the gas turbine engine;
- and
- a dual valve system comprising:
- a valve body coupled to the first pneumatic tube;
- a valve disc operably disposed within the valve body;
- a globe housing comprising a spherical body coupled to the second pneumatic tube;
- a globe butterfly valve disc operably disposed within the globe housing;
- and
- a linkage system operably coupled to the valve disc and the globe butterfly valve disc, wherein the globe housing differs in geometry from the valve body such that opening of a first flow area between the valve disc and the valve body to receive the first airflow from the first pneumatic tube occurs prior to opening of a second flow area between to the globe butterfly valve disc and the globe housing to receive the second airflow from the second pneumatic tube responsive to movement of the linkage system.
A method of operating a dual valve system, the method comprising:
- receiving a first airflow from a gas turbine engine at a first pneumatic tube coupled to a valve body of the dual valve system;
- receiving a second airflow from the gas turbine engine at a second pneumatic tube coupled to a globe housing of the dual valve system;
- driving a valve disc to rotate in the valve body using an actuator;
- and
- translating a rotational force of the actuator through a linkage system operably coupled to the valve disc and a globe butterfly valve disc, wherein the globe butterfly valve disc is disposed within the globe housing and the globe housing differs in geometry from the valve body such that opening of a first flow area between the valve disc and the valve body occurs prior to opening of a second flow area between to the globe butterfly valve disc and the globe housing responsive to the rotational force.
