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.

The invention relates to a non-electric-control medical liquid oxygen two-way decompression tank and a medical central oxygen supply system in the technical field of medical instruments, and aims to solve the problems of electric spark safety risk, low reliability and inconvenience in maintenance in the existing electric control scheme. According to the technical scheme, a pure mechanical structure is adopted, a main air inlet pipeline and a standby air inlet pipeline are included, each air inlet pipeline is provided with a one-way valve and a dual-backup pressure regulating valve set composed of pressure regulating valves connected in parallel, and an outlet of the standby pipeline is connected between a first one-way valve of the main pipeline and the main pressure regulating valve set through a fourth one-way valve; the main path pressure is preset to be higher than the standby path pressure, the one-way valve is driven to be automatically opened and closed through the pressure difference, power-free and seamless switching of the main gas source and the standby gas source is achieved, and the safety valve is arranged to guarantee overpressure safety. The oxygen supply system is mainly used for a hospital center oxygen supply system, and continuous, safe and stable oxygen supply is ensured.

The utility model discloses a tricycle independent suspension system belongs to tricycle suspension technical field, including two mounting brackets, the mounting bracket one side is installed with second universal transmission mechanism, and second universal transmission mechanism output end is connected with the mounting disc head, still includes reduction gearbox and transmission rod, reduction gearbox both sides output end all are connected with first universal transmission mechanism, and reduction gearbox one side fixed mounting has drive motor, and drive motor output shaft is connected with the transmission gear one side in reduction gearbox, in the utility model, through setting up two mounting brackets, through two mounting brackets respectively with tricycle frame installation, make the rear two drive wheels directly disconnect the axis connection, and then make tricycle when one side drive wheel meets the bump, make the drive wheel movement of this one side not or very few directly transmit to the drive wheel of another side to the car body vibration and impact feeling of big -size reduction, promote the riding comfort.
