  • Patent number: 12624804
    Abstract: A device for real-time detection of pipeline gas leakage and leakage prevention includes a gas pipeline, wherein a gas detector is arranged at an outer part of the gas pipeline, a telescopic cylinder is also electrically connected to an outer side of the gas detector, a plurality of three-way elliptical pipes are mounted at a middle segment part of the gas pipeline, a limiting cylinder is fixedly mounted at a bottom port of each three-way elliptical pipe, a separating mechanism is arranged between each limiting cylinder and the three-way elliptical pipe, and a pneumatic mechanism is arranged at a bottom of the limiting cylinder. After detecting gas leakage, the gas detector immediately triggers the telescopic cylinder through an electrical signal, and the pneumatic mechanism triggers the separating mechanism to separate and seal the three-way elliptical pipe when being driven by the telescopic cylinder.
