Abstract

Automatic valve actuator apparatus and valve actuator assemblies are disclosed. The automatic valve actuator apparatus may include a sensor assembly configured to detect a condition and transmit a sensor signal indicating detection of the condition, and a valve actuator assembly configured to be attached to the manual valve and to move the manual valve between open and closed positions. The automatic valve actuator apparatus may additionally include a control assembly configured to receive the sensor signal and to transmit a first control signal to the valve actuator assembly based, at least in part, on the sensor signal. The valve actuator assembly may be further configured to receive the first control signal from the control assembly and to move the manual valve toward the closed position in response to receiving the first control signal.

Claims

1. An automatic actuator apparatus for a manual valve, comprising:

a sensor assembly configured to detect a condition and transmit a sensor signal indicating detection of the condition;

a valve actuator assembly configured to be attached to the manual valve and to move the manual valve between open and closed positions; and

a control assembly configured to receive the sensor signal and to transmit a first control signal to the valve actuator assembly based, at least in part, on the sensor signal, wherein the valve actuator assembly is further configured to receive the first control signal from the control assembly and to move the manual valve toward the closed position in response to receiving the first control signal.

2. The automatic actuator apparatus of claim 1, wherein the valve actuator assembly includes:

a gear assembly configured to be attached to the manual valve; and

a motor operatively connected to the gear assembly to move the manual valve from the open position toward the closed position.

3. The automatic actuator apparatus of claim 2, further comprising a manual override assembly configured to disconnect the motor from the gear assembly to allow a user to move the manual valve between the open and closed positions.

4. The automatic actuator apparatus of claim 2, wherein the control assembly is further configured to detect a force that would prevent the manual override assembly from disconnecting the motor from the gear assembly and that is applied by the gear assembly to the manual valve when the manual valve is moved by the gear assembly to one of the open and closed positions.

5. The automatic actuator apparatus of claim 4, wherein the control assembly is configured to send a second control signal based, at least in part, on detecting the force, wherein the valve actuator assembly is configured to receive the second control signal from the control assembly and to move the manual valve a sufficient amount toward the other of the open and closed positions to remove the force.

6. The automatic actuator apparatus of claim 2, wherein the valve actuator assembly further includes a connector assembly configured to connect the gear assembly and the manual valve, the connector assembly being configured to be attached to the manual valve.

7. The automatic actuator apparatus of claim 6, wherein the connector assembly is configured to be attached to a valve handle of the manual valve.

8. The automatic actuator apparatus of claim 7, where the manual valve is a ball valve, and wherein the connector assembly is configured to be attached to a valve handle of the ball valve.

9. The automatic actuator apparatus of claim 7, where the manual valve is a gate valve, and wherein the connector assembly is configured to be attached to a valve handle of the gate valve.

10. The automatic actuator apparatus of claim 1, wherein the valve actuator assembly and the control assembly are in wired communication with each other.

11. The automatic actuator apparatus of claim 10, wherein the sensor assembly and the control assembly are in wireless communication with each other.

12. The automatic actuator apparatus of claim 1, wherein the sensor assembly is configured to detect the presence of water.

13. The automatic actuator apparatus of claim 1, wherein the control assembly is configured to send a third control signal to the valve actuator assembly at predetermined time intervals, the valve actuator assembly being configured to receive the third control signal from the control assembly and to move the manual valve between open and closed positions in response to receiving the third control signal.

14. A valve actuator and control apparatus for a manual valve, comprising:

a valve actuator assembly configured to be attached to the manual valve and to move the manual valve between open and closed positions, the valve actuator assembly including;

a gear assembly configured to be attached to the manual valve; and

a motor operatively connected to the gear assembly; and

a control assembly configured to receive a sensor signal and to transmit a control signal to the valve actuator assembly based, at least in part, on the sensor signal, wherein the valve actuator assembly is further configured to receive the control signal from the control assembly and to move the manual valve toward the closed position in response to receiving the control signal.

15. An automatic actuator apparatus for a manual valve, comprising:

a sensor assembly configured to detect water and transmit a sensor signal indicating detection of water;

a valve actuator assembly including;

a gear assembly configured to be attached to the manual valve, and

a motor operatively connected to the gear assembly and configured to move the manual valve between open and closed positions;

a control assembly configured to receive the sensor signal and to transmit a control signal to the motor based, at least in part, on the sensor signal, wherein the motor is further configured to receive the control signal from the control assembly and to move the manual valve toward the closed position in response to receiving the control signal; and

a manual override assembly configured to disconnect the motor from the gear assembly to allow a user to move the manual valve between the open and closed positions.
