Abstract
In accordance with at least one aspect of this disclosure, a limiting system for defining a rotational limit of a valve disc of a butterfly valve can include, a crank configured to be disposed on a terminal end of a valve shaft and configured to connect to a drive linkage to drive the crank and rotation of the valve disc. The crank can include a crank arm extending radially outward from the shaft. The crank stop can be configured to contact a portion of the second connecting flange of the first valve to physically limit rotation of the crank and the valve disc within a predefined rotational quadrant.
Claims20
A valve system comprising:
- a first valve configured to connect to one or more additional valves, including:
- a first housing having a first inlet and a first outlet with a cylindrical flow path defined through the first housing between the first inlet and the first outlet along a flow axis, wherein a diametral plane is defined diametrically spanning the cylindrical flow path;
- a first connecting flange extending from the first housing via a first housing extension in a first direction configured to connect the first valve to a second valve and a second housing flange extending from the first housing via a second housing extension in a second direction opposite the first direction configured to connect the first valve to a third valve or connect the first valve to a first structure;
- a first valve disc mounted to a first shaft disposed within the first housing along a rotation axis for rotation between a first position of the first valve disc allowing a first flow amount through the cylindrical flow path and a second position of the first valve disc allowing a second flow amount through the cylindrical flow path;
- wherein a first end of the first shaft extends through the first housing extension and the first connecting flange and is configured to connect to the second valve, and wherein a second end of the first shaft extends through the second housing extension and the second connecting flange and is configured to connect to a crank of the first valve;
- and
- the crank disposed on the second end of the first shaft axially outboard of the second connecting flange configured to rotate the first shaft and the first valve disc between the first position and the second position, the crank including a crank arm configured to connect to a drive linkage and a crank stop configured to limit rotation of the crank to a predefined rotational quadrant of the first valve disc within the first housing to define the first position and the second position of the first valve disc based on an angle of the crank arm relative to the first valve disc.

- a first housing having a first inlet and a first outlet with a flow path defined through the first housing between the first inlet and the first outlet along a flow axis, wherein a plane is defined spanning the flow path;
- and
- a first valve disc mounted to a first shaft disposed within the first housing along a rotation axis for rotation between a first position of the first valve disc allowing a first flow amount through the cylindrical flow path and a second position of the first valve disc allowing a second flow amount through the flow path;
- wherein a first end of the first shaft extends through the first housing and is configured to connect to a second valve, and wherein a second end of the first shaft extends through the first housing opposite the first end of the first shaft and is configured to connect to a crank of the first valve;
- and
- the crank configured to connect to a drive linkage to drive the crank and rotation of the first valve disc, wherein the crank includes a crank arm extending radially outward from the shaft and a crank stop configured to contact a portion of the first housing to physically limit rotation of the crank and the valve disc within a predefined rotational quadrant.
