SAFETY SYSTEM FOR REMOTE SHUT-OFF IN RESOURCE DISTRIBUTION NETWORKS

摘要

A safety system is configured to remotely shut off flow of material through a safety shut- off device. These configurations may include a solenoid valve that couples with an actuator on the shut-off device. In use, the solenoid valve may change state in response to an outside stimuli, like a signal from an operator's central monitoring station. This change in state may cause the actuator to operate, for example, by actuating a latch. The latch may move a flapper in the shut- off device to cease flow of material. In the field, the safety system may find use in pipe and pipeline networks that carry natural gas, wherein remote shut-off of this type can offer rapid, real- time response to problems (e.g., wildfires) in proximity to the networks.
