Form the pressure vessel of sealing；The first half of the sleeping cylinder offers circular hole, which, should closer to the direction of the rear cover
The inside of circular hole is communicated with inlet tube by welding manner；Safety valve and refrigerant charging valve, institute are offered at the top of the sleeping cylinder
It is releasing pressure automatically to state safety valve and be defined to pressure more than 2MPa, and the refrigerant charging valve is angle valve, and the bottom of the sleeping cylinder is opened
Equipped with liquid-returner；
The protecgulum is welded for arc spherical plate and cylindrical shell, and cylinder shell parts are welded in the front end of the sleeping cylinder；It is described
The positive middle part of protecgulum is provided with supercharging sleeve；
The rear cover is plectane, and the front end of the sleeping cylinder is welded with a circle flange, and the excircle of the rear cover and the flange is set
One circle bolt sets seal washer between lid and flange in the rear as fixed and sealing；
The air outlet pipe is the pipe that both ends are rounding off bendings among straight tube, and first end welds and is sealed in the top of the sleeping cylinder
Wall simultaneously stretches out in the sleeping cylinder, and second end stretches upward；The first end opens up flat apart from the position at the top of the sleeping cylinder
Weighing apparatus hole, the lowermost end of round and smooth bending changeover portion open up outage；
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.
For directly being supplemented when requiring supplementation with refrigerant, liquid-returner is needing to lead refrigerant charging valve in the present invention
For release refrigerant during dynamic withdrawal refrigerant, it is ensured that gas-liquid separator safe operation.
