Wall simultaneously stretches out in the sleeping cylinder, and the end is vertical with the roof of the sleeping cylinder；The angle of intermediate rounding off bending is more than 90 °, no
To 180 °, second end is to tilt upward the roof for being directed toward the sleeping cylinder；
The observer is tank gage, and the top of the side wall of the sleeping cylinder and the lower part of side wall are respectively opened up there are one circular hole, this two
A circular hole is respectively welded the connecting tube protruded horizontally up, and transparent observation tube, institute are connected between the end of two connecting tubes
It states observation tube to be made of transparent PVC, as tank gage；It is close by nitrile rubber washer between the observation tube and the connecting tube
Envelope, and fixation is tightened by threaded cap.
Inlet tube is arranged to that the refrigerant into sleeping cylinder is made to increase gas-liquid separation far as possible from air outlet pipe in the present invention
Distance, transverse slat can play the role of stopping the liquid in refrigerant, accelerate gas-liquid separation.
