Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
The utility model provides a kind of safe filling apparatus of refrigerant and is convenient for as shown in Figure 1, the equipment safety is high
Maintenance.
As shown in Fig. 2, pressurized cylinder 14 includes the cylinder 1 and refrigerant cylinder 2 being linked together by attachment base 9, set in cylinder 1
There is cylinder piston 3, is equipped with refrigerant the cylinder piston 4 in refrigerant cylinder 2, passes through piston between cylinder piston 3 and refrigerant the cylinder piston 4
Bar 5 connects.The diameter ratio of cylinder 1 and refrigerant cylinder 2 is 1.5:1-3.5:1.
2 front end of refrigerant cylinder is equipped with refrigerating fluid discharging and feeding 6, and 1 rear end of cylinder is equipped with compressed air inlet and outlet 7, compressed air
Inflation/deflation solenoid valve is set in inlet and outlet 7.The indicating arm 8 of stretches out cylinder 1, indicating arm 8 and piston rod are connected on cylinder piston 3
5 is parallel, and 8 front end of indicating arm is concordant with 4 front end of refrigerant the cylinder piston.
Attachment base 9 is equipped with the mounting rod 10 parallel with refrigerant cylinder 2, deflated position detection switch 11 and aerating position inspection
