An intelligent gas flow regulating valve integrating leakage gas collection and monitoring
ActiveCN121497840BEasy to missSensitive detectionOperating means/releasing devices for valvesLift valveHydrologyMechanics
This invention relates to the field of valve technology, specifically disclosing an intelligent gas flow regulating valve that integrates leaked gas collection and monitoring. The valve body includes a valve shell and a valve core. A valve stem is located at the upper end of the valve core, and a support cylinder is located at the top of the valve shell. The valve stem has a cavity inside, and a magnetic rack is movably mounted on the side wall of the valve stem. A motor is located on the outer wall of the support cylinder, and the output end of the motor is connected to a gear meshing with the magnetic rack. A magnetic plate with the same polarity as the magnetic rack is movably mounted inside the cavity. The cavity also has a telescopic chamber, and a pressure sensor is located on the side wall of the telescopic chamber. Increasing the volume of the telescopic chamber controls the magnetic plate to move away from the magnetic rack, causing the magnetic rack to disengage from the drive gear. Consequently, the valve core falls, blocking the gas path between the inlet and outlet. This invention can not only monitor gas leaks in pipelines but also collect leaked gas and use it to block the gas supply to the household gas pipeline, preventing leaked gas from escaping into the surrounding environment and causing fire safety accidents.
