Abstract
A damper valve includes a base, a valve element pivotally mounted on the base and adjustable valve seat portions on opposite sides of a pivot axis, the valve seat portions being positioned on opposite sides of the blade. Each valve seat portion includes a stationary member fixed to the base, an adjustable element movable relative to the stationary member, and bolts fixing the adjustable element to the stationary member. In addition, adjustment devices are provided for moving the adjustable element toward the valve element to provide a precise fit along the entire length of the valve seat.
Claims17
A damper valve for controlling the flow of fluids through a conduit, comprising:
- a base;
- a valve element having opposed side surfaces, a periphery, and a central plane extending through the periphery;
- an adjustable valve seat including a stationary member mounted on said base and an adjustable element mounted for movement relative to said stationary member, said adjustable element having a side facing said valve element and a side facing away from said valve element;
- means for mounting said valve element for pivoting movement relative to said base into a closed position in which a portion of at least one of said opposed side surfaces of said valve element is in sealing engagement with said valve seat;
- and
- means for adjusting said adjustable element in a direction generally perpendicular to said central plane, when said valve element is in the closed position, by engaging the side of the adjustable element facing away from said valve element, wherein the adjusting means comprises means for moving said adjustable element in a direction generally perpendicular to said portion of the surface with which said valve seat is in sealing engagement.
A damper valve for controlling the flow of fluids through a conduit, comprising:
- a base defining a flowpath through the conduit;
- a valve element having opposed side surfaces, a periphery, and a central plane extending through the periphery;
- an adjustable valve seat including a stationary member mounted on said base and an adjustable element mounted for movement relative to said stationary member, said adjustable element having a side facing said valve element and a side facing away from said valve element;
- means for mounting said valve element for pivoting movement relative to said base into a closed position in which a portion of at least one of said opposed side surfaces of said valve element is in sealing engagement with said valve seat;
- and
- means for adjusting said adjustable element in a direction generally perpendicular to said central plane, when said valve element is in the closed position, by engaging the side of the adjustable element facing away from said valve element, wherein said side of said adjustable element facing away from said valve element lies within said flowpath.
A damper valve for controlling the flow of fluids through a conduit comprising:
- a base;
- a valve element having surfaces for engagement with a valve seat, a periphery, and a central plane extending through the periphery;
- an adjustable valve seat mounted on said base, said adjustable valve seat including a stationary member mounted on said base and all adjustable element mounted for movement relative to said stationary member;
- means for mounting said valve element on said base for pivoting movement into a closed position in which at least one of said surfaces of said valve element is in sealing engagement with said valve seat;
- and
- means for adjusting said adjustable element in a direction generally perpendicular to said central plane, when said valve element is in the closed position, wherein the adjusting means comprises means for moving said adjustable element in a direction perpendicular to the surface of said valve element which said valve seat engages.
A damper valve for controlling the flow of fluids through a conduit, comprising:
- a base;
- a valve element having opposed side surfaces, a periphery, and a central plane extending through the periphery;
- an adjustable valve seat including a stationary member mounted on said base and an adjustable element mounted for movement relative to said stationary member, said adjustable element having a side facing said valve element and a side facing away from said valve element;
- means for mounting said valve element for pivoting movement relative to said base, said valve element having a closed position in which at least one of said opposed side surfaces of said valve element is in sealing engagement with said stationary member of said valve seat and at least a portion of said adjustable element;
- and
- means for adjusting said adjustable element in a direction generally toward said central plane when said valve element is in the closed position.
