A fluid piping system including a fluid strainer, the fluid strainer comprising:
- a housing comprising a first valve chamber comprising an inlet port in communication with an upstream piping element, a first port, and a second port, and a second valve chamber comprising a third port, a fourth port, and an outlet port in communication with a downstream piping element, wherein the first valve chamber is separated from the second valve chamber by an inner wall comprising two distinct portions, a first portion being substantially planar and a second portion being inclined relative to the first portion;
- a first strainer chamber comprising a first strainer inlet in communication with the first port and a first strainer outlet in communication with the third port;
- a second strainer chamber comprising a second strainer inlet in communication with the second port and a second strainer outlet in communication with the fourth port;
- a first seal assembly comprising a first pivotable member, a first disk comprising a first disk stem extending from a first side of the first disk to the first port and a second disk stem extending from an opposing second side of the first disk to the second port, a first disk guide fixedly positioned within the first port and a second disk guide fixedly positioned within the second port, and a first coupler extending from the first pivotable member towards an exterior edge of the first disk and connecting the first pivotable member to the first disk, wherein the first pivotable member is movable to cause the first disk to move within the first valve chamber into sealing engagement against either of the first port or the second port, and wherein the first disk stem is linearly translatable through the first disk guide and into at least the first strainer inlet when the first disk is moved into sealing engagement against the first port and the second disk stem is linearly translatable through the second disk guide and into at least the second strainer inlet when the first disk is moved into sealing engagement against the second port;
- and
- a second seal assembly comprising a second pivotable member, a second disk comprising a third disk stem extending from a first side of the second disk to the third port and a fourth disk stem extending from an opposing second side of the second disk to the fourth port, a third disk guide fixedly positioned within the third port and a fourth disk guide fixedly positioned within the fourth port, and a second coupler extending from the second pivotable member towards an exterior edge of the second disk and connecting the second pivotable member to the second disk, wherein the second pivotable member is movable to cause the second disk to move within the second valve chamber into sealing engagement against either of the third port or the fourth port, wherein the third disk stem is linearly translatable through the third disk guide and into at least the first strainer outlet when the second disk is moved into sealing engagement against the third port, and wherein the fourth disk stem is linearly translatable through the fourth disk guide and into at least the second strainer outlet when the second disk is moved into sealing engagement against the fourth port;
- wherein the first disk guide is fixedly positioned at a center of the first port, and a plurality of flow routing vanes extend from the first disk guide to an edge of the first port,
- wherein the second disk guide is fixedly positioned at a center of the second port, and a plurality of flow routing vanes extend from the second disk guide to an edge of the second port,
- wherein the third disk guide is fixedly positioned at a center of the third port, and a plurality of flow routing vanes extend from the third disk guide to an edge of the third port,
- wherein the fourth disk guide is fixedly positioned at a center of the fourth port, and a plurality of flow routing vanes extend from the fourth disk guide to an edge of the fourth port, and
- wherein the plurality of flow routing vanes each comprise a planar surface with a first end and a second end, the planar surface being oriented so as to be substantially parallel to a flow direction of the fluid, and the first end of each of the flow routing vanes axially extending from a respective disk guide to an edge of a respective port at the second end.
