METHOD AND SYSTEM OF A VALVE

摘要

Valves. At least some of the example valves include: a valve body; a valve housing; and a piston that defines a proximal end and a distal end, the piston disposed in a piston bore of the valve housing. The valve defines a closed orientation by a first rotational orientation of the valve housing relative to the valve body, and the valve defines an open orientation by a second rotational orientation of the valve housing distinct from the first rotational orientation.

1. A valve assembly comprising:
a valve body that comprises
a first counter bore with a first diameter and a first central axis;a second counter bore disposed within the first counter bore, the second counter bore having a second central axis parallel to and offset from the first central axis, and the second diameter smaller than the first diameter;an inlet port fluidly coupled to the first counter bore; andan outlet port fluidly coupled to the second counter bore; a valve housing comprising
a circular stem member that defines a third central axis;a piston receptacle member that defines a piston bore, the piston bore defines a fourth central axis perpendicular to the third central axis;a flow passage defined in the circular stem member, the flow passage fluidly coupled to the piston bore;the circular stem member disposed within the second counter bore;the piston receptacle member disposed within the first counter bore; andthe second and third central axis coaxial; a piston that defines a proximal end and a distal end, the piston disposed in the piston bore of the valve housing; the valve assembly defines closed orientation by a first rotational orientation of the valve housing relative to the valve body, and the valve assembly defines an open orientation by a second rotational orientation of the valve housing distinct from the first rotational orientation.
