A sealing check valve
A Check Valves is provided having a valve body and a sealing assembly provided within the valve body. The valve body has an inner wall surface, an inlet port, an outlet port and a valve seat adjacent or surrounding the inlet port. The sealing assembly comprising an armature having a proximal end and a distal end, and a sealing member pivotally attached to the distal end of the armature at a seal pivot joint. The proximal end of the armature is pivotally attached to the inner wall surface of the valve body at at least one wall pivot joint. The sealing member is biased, via a biasing force, in a seated position against the valve seat.
Another check valve is also provided. The CHECK VALVES has a valve body and a sealing assembly within the valve body. The valve body has an inner wall surface, an inlet port, an outlet port and a valve seat adjacent or surrounding the inlet port. The sealing assembly comprises an armature having a proximal end and a distal end, and a sealing member pivotally attached to the distal end of the armature at a seal pivot joint, wherein the sealing member is rotatable about a first rotational axis through the seal pivot joint. The proximal end of the armature is pivotally attached to the inner wall surface of the valve body at at least one wall pivot joint such that the sealing member is translatable along an arcuate path that is substantially aligned with the valve seat. The sealing member is biased, via a biasing force, in a seated position against the valve seat.
Another valve is provided having housing that defines an interior volume and which has at least two flow ports therethrough, and a cover having a sealing assembly pivotally attached thereto. The cover is removably attachable to the housing in a plurality of orientations to selectively orient the sealing assembly adjacent any one of the ports in the housing such that fluid is permitted to flow into the interior volume of the housing through the adjacent port. The sealing assembly prevents fluid from flowing out of the interior volume through the adjacent port. The sealing assembly has an armature pivotally attached to the cover, a biasing member between the cover and the armature, a seal pivot joint, and a sealing member pivotally attached to the diverter at the seal pivot joint. The sealing member has at least one lip that extends around a perimeter of the sealing member and is supported thereby to contact the housing.Cast Steel Valves
