A New Portable Fluid Circuit Filling Device

Abstract

The invention provides a novel portable fluid loop filling device, used for filling a fluid loop. Two ends of the fluid loop are respectively provided with a first quick-connection plug and a second quick-connection plug, wherein the first and second quick-connection plugs have a self-closing function. The device comprises a pipeline system, a mass flow meter, a vacuumizing system, a gas distribution system, a liquid storage tank and a recovery tank, as well as a liquid inlet pipe and a liquid return pipe matched with the two quick-connection plugs. The fluid loop filling device can be integrated on a movable operation platform, and is convenient to convey; the device can be used to perform operations of blowdown replacement, vacuumizing, working medium filling and loop drying on the fluid loop, and degas a working medium in the liquid storage tank, thus being capable of effectively preventing non-condensable gas and impurities from entering the fluid loop in a filling process, and accurately measuring filling amount; the fluid loop drying time can be effectively shortened, timely filling experiment is facilitated, and the device is suitable for being popularized and applied.

Description
