Valve assembly with valve position indicator

摘要

A valve assembly may include a valve disposed in a flow path and an actuator disposed above the valve. The actuator may be configured to actuate the valve to move between an open position and a closed position. The valve may also include a rocking member disposed above the actuator and configured to move with the valve. The valve may also include a pair of first and second position sensors disposed above and parallel to the actuator. The pair of first and second position sensors may be configured to detect a position of the rocking member. The position of the rocking member may be indicative of a position of the valve.

1. A valve assembly comprising:
a valve disposed in a flow path; an actuator disposed above the valve and configured to actuate the valve to move between an open position and a closed position; a rocking member disposed above the actuator and configured to move with the valve; and a pair of first and second position sensors disposed above and parallel to the actuator and configured to detect a position of the rocking member, wherein the position of the rocking member is indicative of a position of the valve, and wherein the rocking member is configured to move between a first position to activate the first position sensor and a second position to activate the second position sensor, and wherein the rocking member comprises an V-shaped rocking member having a first arm and a second arm substantially perpendicular to the first arm, wherein the V-shaped rocking member is configured to move between the first position in which the first arm is brought within a sensing range of the first position sensor and the second position in which the second arm is brought within a sensing range of the second position sensor.
