Abstract
A valve assembly and system, method, and apparatus thereof can comprise a valve body having a side surface and a valve body contact surface; a ring surrounding the valve body such that an inner surface of the ring is slidably engaged with the side surface of the valve body; and a retainer at an upper surface of the ring and movable with the ring relative to the valve body such that the retainer moves with the ring as the ring slides along the side surface of the valve body.
Claims20
A valve assembly with self-adjusting valve portion comprising:
- a valve movable in an axial direction of the valve assembly relative to a contact surface as a seat;
- and
- a biasing member movable in the axial direction of the valve assembly responsive to operation of the valve,
- wherein the valve includes:
- a valve body having a radial side surface and a valve contact surface, on a bottom side of the valve body, configured to contact the contact surface, the valve contact surface being adjacent to the radial side surface of the valve body,
- a ring as the self-adjusting valve portion, the ring circumscribing the valve body such that an inner surface of the ring directly contacts the radial side surface of the valve body, wherein a bottom surface of the ring contacts the contact surface under a condition that the valve is seated on the contact surface, and
- a rigid retainer ring bonded to the ring such that an upper surface of the ring is in contact with the rigid retainer ring, the rigid retainer ring being distinct from and more rigid than the ring,
- wherein in a first state of the valve contact surface of the valve body, an entirety of the ring and an entirety of the rigid retainer ring are operative to move together with the valve body away from contact surface in the axial direction, and
- wherein in a second state of the valve contact surface where the valve contact surface has worn in the axial direction due to prior operation of the valve assembly, during the operation of the valve assembly under a condition that the bottom surface of the ring becomes seated on the contact surface, the valve body is operative to move toward the contact surface, relative to the ring and the rigid retainer ring, to create a space between an upper surface of the valve body and a bottom surface of the rigid retainer ring.
A method regarding a valve assembly, comprising:
- providing a valve body of the valve assembly, the valve body defining a radial side surface and a valve contact surface on a first side of the valve body, the valve contact surface being adjacent to the radial side surface of the valve body;
- providing a ring, the ring circumscribing the valve body such that an inner surface of the ring directly contacts the radial side surface of the valve body;
- providing a retainer ring, the retainer ring being fixed to the ring such that at least a portion of an upper surface of the ring is covered by the retainer ring;
- and
- operating the valve assembly said operating the valve assembly including moving the valve body toward a base contact surface of a valve base, wherein said moving the valve body toward the valve contact surface of the valve base causes the valve body to slide along the inner surface of the ring toward the base contact surface of the valve base upon the ring contacting the base contact surface of the valve base prior to the valve contact surface contacting the base contact surface of the valve base,
- wherein the valve body is slidably movable along the inner surface of the ring during said operating the valve assembly subsequent to the valve contact surface of the valve body wearing from prior operation of the valve assembly, and
- wherein the valve body sliding along the inner surface of the ring toward the base contact surface creates a space between an upper surface of the valve body and a bottom surface of the retainer ring.
A valve assembly comprising:
- a valve body having a side surface and a valve body contact surface;
- a ring surrounding the valve body such that an inner surface of the ring is slidably engaged with the side surface of the valve body;
- and
- a rigid retainer at a first surface of the ring and movable with the ring relative to the valve body such that the rigid retainer moves with the ring as the ring slides along the side surface of the valve body, the rigid retainer being distinct from and more rigid than the ring,
- wherein the valve body is movable relative to the ring and the rigid retainer during operation of the valve assembly between a first position where an upper surface of the valve body contacts a bottom surface of the rigid retainer and a second position where no portion of the upper surface of the valve body contacts the bottom surface of the rigid retainer.
