Abstract
A check valve may include: a check seat defining a flow path and including downstream and upstream sides; a poppet assembly including a poppet body and a poppet seat, the poppet seat configured to form a fluid-tight seal with the downstream side; at least one first extension extending upstream from the poppet body and including a roller; and at least one cam arm disposed at least partially upstream of the poppet body and the check seat and configured to engage with the at least one roller; and at least one cam arm disposed at least partially upstream of the poppet body and the check seat and configured to engage with the at least one roller. Engagement between the at least one cam arm and the at least one roller is configured to urge the poppet in the upstream direction.
Claims20
A check valve comprising:
- a check seat defining a flow path and extending about a longitudinal axis, the check seat comprising a downstream side and an upstream side;
- a poppet assembly comprising a poppet body and a poppet seat, the poppet seat configured to form a fluid-tight seal with the downstream side, the poppet body being configured to obstruct the flow path;
- at least one first extension extending from the poppet body in an upstream direction, the at least one first extension comprising a roller;
- and
- at least one cam arm disposed at least partially upstream of the poppet body and the check seat, the at least one cam arm configured to engage with the at least one roller,
- wherein, when a fluid pressure created by a fluid in the flow path reaches a cracking pressure, the poppet assembly is configured to move in a downstream direction, thereby breaking the fluid-tight seal,
- wherein engagement between the at least one cam arm and the at least one roller is configured to urge the poppet in the upstream direction,
- wherein, when the fluid-tight seal is formed between the poppet seat and the valve check seat, the poppet is in the closed position, and
- wherein, when the fluid-tight seal is broken and the poppet is moved downstream, the poppet is in the open position.
A check valve comprising:
- a valve body defining a flow path and extending about a longitudinal axis;
- a check seat extending from the valve body, the check seat comprising:
- a downstream side;
- an upstream side;
- an interior space defined between the downstream side and the upstream side, the interior space defining a fluid flow path;
- a first extension extending from the upstream side in an upstream direction;
- and
- a second extension extending from the upstream side in the upstream direction;
- a poppet assembly comprising a poppet body and a poppet seat, the poppet seat configured to form a fluid-tight seal with the downstream side in a closed position, the poppet body being configured to obstruct the fluid flow path;
- a third extension extending from the poppet body in the upstream direction, the third extension comprising a first roller;
- a fourth extension extending from the poppet body in the upstream direction, the fourth extension comprising a second roller;
- a first cam arm extending from the first extension in a downstream direction, the first cam arm being configured to engage with the first roller;
- a second cam arm extending from the second extension in a downstream direction, the second cam arm being configured to engage with the second roller,
- wherein the poppet assembly is configured to move in a downstream direction into an open position, thereby moving the first roller along the first cam arm and the second roller along the second cam arm.
