Technical Field
[0001] This utility model relates to the field of chemical safety switch technology, and in particular to a safety device capable of automatically sensing and cutting off. Background Technology
[0002] Chemical safety switches are critical devices used in chemical production processes to ensure the safety of equipment and personnel. They automatically trigger protective measures by monitoring changes in specific parameters to prevent accidents or to quickly respond to accidents in the event of an accident. Their primary function is to immediately cut off power, close valves, or activate emergency systems when hazardous conditions are detected, thus protecting equipment and personnel. Since chemical valves are typically shut off manually, a safety switch is necessary to ensure chemical safety.
[0003] Currently, chemical safety switches are typically used in chemical pipelines for transporting and processing liquids and gases. However, chemical pipelines are easily damaged by external factors during long-term use, leading to leakage of internal chemical products. This prevents the switches from sensing and quickly shutting off the valves in time, resulting in significant loss of chemical products and economic losses. Utility Model Content
