Abstract
A valve seat assembly includes a gasket retainer comprising an outer wall, an inner wall, an upper face extending between the outer and inner walls, and a lower face extending between the outer and inner walls. The inner wall defines an insert receiving bore extending from the upper face inwardly toward the lower face to a recess that receives a gasket. A gasket is located in the recess. A retainer insert is located in the insert receiving bore that applies a compressive force to the gasket.
Claims20
A valve seat assembly comprising:
- a gasket retainer comprising:
- an outer wall;
- an inner wall;
- an upper face extending between the outer and inner walls;
- a lower face extending between the outer and inner walls;
- the inner wall defining an insert receiving bore extending from the upper face inwardly toward the lower face to a recess that receives a gasket;
- a gasket located in the recess;
- and
- a retainer insert located in the insert receiving bore that applies a compressive force to the gasket.
A valve assembly comprising:
- a valve stem including a sealing end;
- and
- a valve seat assembly comprising:
- a gasket retainer comprising
- an outer wall;
- an inner wall;
- an upper face extending between the outer and inner walls;
- a lower face extending between the outer and inner walls;
- the inner wall defining an insert receiving bore extending from the upper face inwardly toward the lower face to a recess that receives a gasket;
- a gasket located in the recess;
- and
- a retainer insert located in the insert receiving bore, the retainer insert comprising an inner wall defining a valve stem receiving bore through which the valve stem extends such that the sealing end of the valve stem engages the gasket in a closed configuration and disengages the gasket in an open configuration.
A paint coating system comprising:
- a paint coating robot comprising an arm assembly and a coating apparatus for urging paint toward a work piece;
- and
- a valve assembly that controls paint delivery to the paint coating robot, the valve assembly comprising:
- a valve stem including a sealing end;
- and
- a valve seat assembly comprising:
- a gasket retainer comprising
- an outer wall;
- an inner wall;
- an upper face extending between the outer and inner walls;
- a lower face extending between the outer and inner walls;
- the inner wall defining an insert receiving bore extending from the upper face inwardly toward the lower face to a recess that receives a gasket;
- a gasket located in the recess;
- and
- a retainer insert located in the insert receiving bore, the retainer insert comprising an inner wall defining a valve stem receiving bore through which the valve stem extends such that the sealing end of the valve stem engages the gasket in a closed configuration and disengages the gasket in an open configuration.
