いたり、制御が困難になる等の不都合がある。(Prior art and its problems) In gas control valves that use moving coils or moving magnets, the diaphragm, which is a component thereof,
Since the valve body, moving coil, and moving magnet constitute a mechanical vibration system, when certain conditions of gas pressure and flow rate are met, the system resonates and vibrates at a natural frequency. In addition, the moving coil, the solenoid that drives the moving magnet, and the capacitance on the DC power supply side constitute an electrical vibration system, and its natural frequency is equal to or close to the natural frequency of the mechanical vibration system. , the mechanical vibration system vibrates with a large amplitude. If the gas pressure and flow rate conditions at the time of resonance are within the normal use area of the gas appliance, resonance will occur during normal use and may become a source of noise. There are disadvantages such as shortening the life of the components and making control difficult.
