Abstract
A multi-tubing pinch valve assembly including a receiving space defined between a pinch protrusion and tubing contact body. The multi-tubing pinch valve assembly is moveable between a retracted state and an extended state. In the extended state, multiple tubes disposed in the receiving space are pinched, restricting flow therethrough. In the retracted state, multiple tubes are capable of being loaded into and/or out of the receiving space.
Claims35
A multiple-tube pinch valve assembly, comprising:
- a camshaft extending a length along a longitudinal axis of the camshaft, the camshaft comprising at least one cam disposed along the length, the at least one cam comprising a cam profile shape defined around the longitudinal axis and a periphery of the camshaft;
- a platen offset a distance from the longitudinal axis, the distance at least partially defining a space configured to receive multiple fluid flow tubes;
- and
- an anvil assembly comprising a cam contact portion disposed on a first side of the anvil assembly and a pinch edge disposed on a second side of the anvil assembly, wherein the anvil assembly is moveable between a retracted state such that the pinch edge is disposed outside of the space and an extended state such that the pinch edge is disposed inside the space adjacent the platen, and wherein the anvil assembly moves between the retracted state and the extended state by a rotation of the camshaft and the at least one cam.
A multiple-tube pinch valve assembly, comprising:
- a motor comprising an output shaft;
- a drive body attached to the output shaft of the motor;
- a camshaft extending a length along a longitudinal axis of the camshaft, the camshaft comprising at least one cam disposed along the length, the at least one cam comprising a cam profile shape defined around the longitudinal axis and a periphery of the camshaft and;
- a cam drive body attached to the camshaft;
- a platen offset a distance from the longitudinal axis, the distance at least partially defining a space configured to receive multiple fluid flow tubes;
- and
- an anvil assembly comprising at least one cam follower disposed on a first side of the anvil assembly and a pinch edge disposed on a second side of the anvil assembly, wherein rotation of the output shaft of the motor transmits power from the drive body to the cam drive body causing the camshaft to rotate relative to the anvil assembly and move the anvil assembly between a retracted state, such that the pinch edge is disposed outside of the space, and an extended state, such that the pinch edge is disposed inside the space adjacent the platen, and wherein the anvil assembly moves between the retracted state and the extended state by rotation of the camshaft and the at least one cam.
A multi-tubing pinch valve assembly, comprising:
- a hinge plate extending a length from a first point to a second point, the hinge plate comprising:
- a pivot axis disposed adjacent the first point of the hinge plate;
- and
- a pinch protrusion disposed between the first point and the second point, the pinch protrusion extending from a surface of the hinge plate;
- a platen comprising a body offset a distance from the hinge plate, the platen comprising a tubing contact portion disposed on a surface of the platen;
- an actuator operatively connected to the hinge plate adjacent the second point, wherein the actuator is moveable between a retracted state and an extended state, wherein, in the retracted state, the hinge plate is pivoted about the pivot axis such that the second point of the hinge plate is separated from the platen by a first distance, wherein, in the extended state, the hinge plate is pivoted about the pivot axis such that the second point of the hinge plate is separated from the platen by a second distance, and wherein the first distance is greater than the second distance.
A multi-tubing pinch valve assembly, comprising:
- an array of valves disposed adjacent one another, wherein each valve in the array of valves comprises:
- a hinge plate extending a length from a first point to a second point, the hinge plate comprising:
- a pivot axis disposed adjacent the first point of the hinge plate;
- and
- a pinch protrusion disposed between the first point and the second point, the pinch protrusion extending from a surface of the hinge plate;
- a tubing contact body offset a distance from the hinge plate;
- an actuator operatively connected to the hinge plate adjacent the second point, wherein the actuator is moveable between a retracted state and an extended state, wherein, in the retracted state, the hinge plate is pivoted about the pivot axis such that the second point of the hinge plate is separated from the tubing contact body by a first distance, wherein, in the extended state, the hinge plate is pivoted about the pivot axis such that the second point of the hinge plate is separated from the tubing contact body by a second distance, and wherein the first distance is greater than the second distance.
