AI Technical Summary
Technical Problem
Existing gas equipment condition monitoring devices are easily damaged in high-concentration gas and sulfur-containing environments, and the chemical properties of the catalyst undergo irreversible changes.
Method used
The device uses a mesh bag and a back cover filled with molecular sieves to filter sulfides, and a gas flow regulation component is set up to seal the air inlet under high concentration of gas to prevent the detection element from being in contact with high concentration of gas for a long time.
Benefits of technology
Effective filtration of sulfides prevents changes in the chemical properties of the catalyst, avoids damage to detection elements, and ensures normal operation of the device under high concentrations of fuel gas.

Abstract
The utility model discloses a gas equipment state detection device, which belongs to the technical field of gas sensors, and comprises a base and a miniature push cylinder, the surface of the base is provided with a shell, one end of the shell far away from the base is provided with a gas inlet channel assembly, the shell is internally provided with a mounting seat, one side of the mounting seat is fixedly connected with the base, and the other side of the mounting seat is fixedly connected with the miniature push cylinder. A detection element and a compensation element are arranged on the other side of the mounting base, a through pipe is arranged in the center of the mounting base, an air flow adjusting assembly is arranged at the end, away from the base, of the through pipe, and the micro push cylinder is arranged in the base. By arranging the mesh bag, the rear cover and the molecular sieve, sulfide in sulfur-containing air can be filtered, irreversible chemical change of a catalyst in the detection element is prevented, and by arranging the air flow adjusting assembly, when it is detected that the temperature of the detection element is abnormal, the micro push cylinder pushes the flow limiting cover to close the air inlet, and the air flow is adjusted. Only a small amount of fuel gas is allowed to enter through the flow limiting hole, and poisoning of a detection element is avoided while the detection function is maintained.
