Casing vent security device
View Patent ↗A casing vent security device includes an in-line section in communication with a casing vent, the in-line section having an ambient air passageway for selectively allowing ambient air to pass through the in-line section and into the vent. The device further includes a plurality of sensors disposed within the in-line section for monitoring the ambient air passing through the in-line section. The device still further includes at least one mechanism for selectively occluding the passage of ambient air into the vent upon receiving a signal from the sensors. The device provides information on the plurality of sensors and the vent.
1. A casing vent security device adapted for use with a casing vent, such as a well casing vent, comprising:
an in-line section in communication with a casing vent, the in-line section having an ambient air passageway for selectively allowing ambient air to pass through the in-line section and into the vent;
a plurality of sensors disposed within the in-line section for monitoring the ambient air passing through the in-line section;
occlusion means positioned in the in-line section for selectively occluding the passage of ambient air into the vent upon receiving a signal from the sensors; and
signaling means for providing information on the plurality of sensors and the vent wherein the occlusion means includes a first plunger valve and a second slide valve.
2. The device of claim 1 wherein the sensors are capable of sensing at least one of: mechanical, chemical, biological, radioactive, gas phase, liquid phase and solid phase contaminants.
3. The device of claim 1 further including an adapter unit for adapting the casing vent security device retrofittingly to an existing vent.
4. The device of claim 1 further including a housing for encompassing at least the in-line section.
5. The device of claim 1 in combination with a remote monitoring system for remotely monitoring device activities.
6. The device of claim 1 wherein a signal indicates potential contamination of the ambient air passing through the in-line section.
7. The device of claim 1 further comprising a solenoid for actuating at least one of the valves.
8. A casing vent security device adapted for use with a casing vent, such as a well casing vent, comprising:
an in-line section in communication with a casing vent, the in-line section having an ambient air passageway for selectively allowing ambient air to pass through the in-line section and into the vent;
a plurality of sensors disposed within the in-line section for monitoring the ambient air passing through the in-line section;
a first plunger valve and a second slide valve, the first valve positioned in the in-line section and the second valve positioned downstream of the first valve, the valves for selectively occluding the passage of ambient air into the vent upon receiving a signal from the sensors; and
signaling means for providing information on the plurality of sensors and the vent.
9. The device of claim 8 wherein the first valve is spring actuated.
10. The device of claim 8 wherein the second valve is in operational association with motor means to open or close the second valve in sliding fashion.
