System and method for controlling flow in a plurality of valves

摘要

A system includes a set of valves and a handle, in which one valve in the set of valves is to be open at one time, and the handle is configured to move the valve between an open position and a closed position. The handle is configured to engage and disengage with the valve only when the valve is in the closed position such that the handle is not removed from the valve when the valve is in the open position. Thus, the system facilitates the sequential opening of valves in a set of valves by generally allowing a limited number of valves to be open at one time.

1. A system comprising:
a valve; and a handle configured to move the valve between open and closed positions, wherein the handle is configured to engage and disengage with the valve by moving the handle in an axial direction relative to a rotational axis of the valve, wherein the handle is configured to engage and disengage with the valve in only one of the open or closed positions of the valve, wherein a locking mechanism of the valve comprises a flange having at least one slot extending between a first surface and a second surface of the flange in the axial direction, and a locking feature of the handle comprises at least one hook configured to extend through the at least one slot and catch on the second surface of the flange while the handle is moved between the open position and the closed position.
