A micro-flow regulating valve was introduced into an experimental device used for liquid vapor pressure measurements, to enable the accurate and control of the pressure of the system and address the problem of backward air flow into the experimental system. Desirable results were obtained in the experimental process with the use of the micro-flow regulating valve in the experimental device.
