CLAIMS

WHAT IS CLAIMED IS:

1. A device for indicating a position of a valve comprising:

(A) a mechanical mechanism comprising:

(i) a first gear configured to operatively connect to the valve;

(ii) a second gear coupled to a first end portion of a first support, wherein the second gear is sized and configured so as to mate with the first gear;

(iii) a third gear coupled to a second end portion of the first support;

(iv) a fourth gear coupled to a first end portion of a second support, wherein the fourth gear mates with the third gear; and

(v) a support member for supporting the first support and the second support, and adapted to affix the mechanical mechanism to the valve; and

(B) an output device operatively connected to the mechanical mechanism, wherein the output device provides a signal that is indicative of the position of the valve.

2. The device of claim 1 wherein the output device is operatively connected to a second end portion of the second support.

3. The device of claim 2 wherein the output device comprises one selected from the group consisting of a rotary sensor, two limit switches, a quarter turn indicator, and any combination of two or more of the foregoing.

4. The device of claim 2 wherein the output device is operatively connected to the second end portion of the second support with a coupling and a flexible shaft.

5. The device of claim 4 wherein the flexible shaft has a length in the range of from about 1 to about 20 feet.

6. The device of claim 1 wherein the device for indicating the position of the valve is operatively coupled to a hand wheel of the valve so as to provide a signal that is indicative of the position of the valve when the valve is actuated.

7. The device of claim 1 wherein a longitudinal axis of the second gear is substantially orthogonal relative to a longitudinal axis of the first gear.

8. The device of claim 7 wherein a longitudinal axis of the third gear is substantially orthogonal relative to a longitudinal axis of the fourth gear.

9. The device of claim 1 wherein the output device comprises a rotary sensor coupled to the second end portion of the second support, wherein the rotary sensor has a number of turns in the range of from about 50 to about 100 turns and transmits a signal indication of a position of the manual valve.

10. The device of claim 1 wherein the mechanical mechanism is positioned adjacent or below a hand wheel of the valve.

11. The device of claim 1 wherein a position indicator sensor is operatively connected to the output device and receives the signal that is indicative of a position of the valve and in response to the signal provides an indication of the position of the valve.

12. The device of claim 1 wherein a wireless position indicator sensor is operatively connected to the output device and receives the signal that is indicative of a position of the valve and in response to the signal provides an indication of the position of the valve.

13. A method for indicating the position of a valve, the method comprising:

(A) operatively connecting the device of claim 1 to a valve having a hand wheel.

14. The method of claim 12, wherein the device is operatively coupled to the hand wheel of the valve and positioned adjacent to or below the hand wheel of the valve.

15. A device for indicating a position of a valve comprising:

(A) a mechanical mechanism comprising:

(i) a first gear configured to operatively connect to the valve;

(ii) a second gear operatively connected to the first gear, wherein the second gear is sized and configured so as to mate with the first gear;

(iii) a third gear operatively connected to the second gear;

(iv) a fourth gear operatively connected to the third gear; and

(v) a member for supporting the each of the gears, and adapted to affix the mechanical mechanism to the valve; and

(B) an output device operatively connected to the mechanical mechanism, wherein the output device provides a signal that is indicative of the position of the valve.

16. A mechanical mechanism for use with a valve, the mechanical mechanism comprising:

(A) a first gear configured to operatively connect to the valve;

(B) a second gear coupled to a first end portion of a first support, wherein the second gear is sized and configured so as to mate with the first gear;

(C) a third gear coupled to a second end portion of the first support;

(D) a fourth gear coupled to a first end portion of a second support, wherein the fourth gear mates with the third gear; and

(E) a support member for supporting the first support and the second support, and adapted to affix the mechanical mechanism to the valve;

wherein the mechanical mechanism is configured to be operatively connected to an output device capable of producing a signal that is indicative of the position of the valve.

17. An output device for use with a valve, the output device comprising:

(A) at least one sensor comprising a rotary sensor, two limit switches, a quarter turn indicator, position indicator sensor and any combination of two or more of the foregoing;

wherein the output device is configured to receive a mechanical input as the hand wheel of the valve is operated and in response provide a signal that is indicative of the position of the valve.

18. The output device of claim 17 further comprising a position indicator sensor that is operatively connected to the at least one sensor, wherein the position indicator sensor receives the signal that is indicative of a position of the valve and in response to the signal provides an indication of the position of the valve.
