| description | The utility model discloses an automatic vacuum pumping liquid filler of digital refrigerating liquid, which comprises a host machine and a handle, wherein the host machine is provided with a control panel which is provided with a pressure meter, a vacuum detector, a central processing unit CPU and a display screen, and a closing electromagnetic valve which is connected with a vacuum pump and prevents oil return is arranged in the host machine. One side of the host machine is provided with a vacuum interface, a liquid filling interface and a cable interface. A turbine flow sensor, a vacuum electromagnetic valve, a liquid filling electromagnetic valve and a terminal quick connector are arranged in the handle, wherein the turbine flow sensor is connected with the liquid filling electromagnetic valve, and the vacuum electromagnetic valve and the liquid filling electromagnetic valve are connected with the terminal quick connector. With the adoption of the sensing technology of direct flow quantity, the utility model has the advantages of high ccuracy and high safety when the global operation of a system is in a low pressure state, especially a hydrocarbons refrigerant. |
