Abstract: A gas filtering rubber pipe and a pressure regulating valve bank are disclosed. The pressure regulating valve bank includes an angle valve, a pressure reducing valve and the gas filtering rubber pipe including a pipe body and a filtering mechanism. The filtering mechanism includes a shell assembly and a connector arranged at a lower end of the shell assembly, the shell assembly is provided with a separation cavity and a gas outlet channel located in an upper portion of the shell assembly. The gas outlet channel can be communicated with the separation cavity. A lower end of the connector is provided with a connecting portion fixedly connected with an upper end of the pipe body, an upper end of the connector is provided with a filtering barrier. A gas outlet hole is arranged in a peripheral wall of the connector connected with the filtering barrier.

Abstract: A driving device using temperature measurement, a driving method using temperature measurement and a dual-gas-source valve control system, wherein the device includes at least two thermocouple components; and a magnetic-drive assembly, wherein each thermocouple component is connected with the magnetic-drive assembly, the thermocouple components are capable of driving the magnetic-drive assembly to generate a magnetic flux according to an external temperature, and some of the thermocouple components drive the magnetic-drive assembly to generate a magnetic flux that is capable of being offset with a magnetic flux generated by the magnetic-drive assembly driven by the other of the thermocouple components.
