Described little U-shaped pipe is positioned at the inside of separator main body, the entrance point of little U-shaped pipe is identical with the entrance point height of large U type pipe, the port of export of little U-shaped pipe is connected with the port of export of large U type pipe, the bottom of little U-shaped pipe is positioned at the bottom of separator main body, the bottom of little U-shaped pipe is provided with back the liquid aperture, and described time the liquid aperture is connected little U-shaped pipe with the bottom of separator main body.
Further: this gas-liquid separator also comprises heating mantles, described heating mantles covers on the outside of separator main body bottom, it is airtight cavity between heating mantles and separator main body, and be full of high temperature high pressure liquid in cavity, heating mantles is provided with the high temperature high pressure liquid entrance that is connected with fluid reservoir and the high temperature high pressure liquid that is connected with cryogenic vaporizer outlet.
The beneficial effects of the utility model are:
1, return in a large number liquid and compressor when shutting down suddenly when freon refrigeration system; it is inner that refrigerant liquid in the cold-producing medium of gas-liquid separator bottom enters little U-shaped pipe by time liquid aperture; make little U-shaped pipe inner equal with the liquid level in gas-liquid separator; when compressor starts again; will take back the refrigerant liquid in little U-shaped pipe in compressor; because little U-shaped pipe is less than the diameter of large U type pipe; therefore the amount that is brought back into the refrigerant liquid in compressor is less; can not cause the liquid hammer accident, protect compressor.
2, constantly heating makes its gasification to the high temperature high pressure liquid in heating mantles to the low pressure liquid in gas-liquid separator, has improved the operating efficiency of compressor.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is described further:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of existing freon gas liquid/gas separator;
In figure: 1 large U type pipe, the port of export of 11 large U type pipes, the entrance point of 12 large U type pipes, 2 system's mufflers, 3 little U-shaped pipes, the port of export of 31 little U-shaped pipes, the entrance point of 32 little U-shaped pipes, 4 separator main bodies, 5 times liquid apertures, 6 heating mantleses, 61 high temperature high pressure liquid outlets, 62 high temperature high pressure liquid entrances, 7 refrigerant liquids, 8 high temperature high pressure liquid, 9U type pipe
