Embodiment 1

[0040] Embodiment 1: a kind of filling process of refrigerant cylinder, specifically comprises the following steps:

[0041] Step 1, start up: first turn on the main power switch, turn on the cooling water circulation system, then turn on the vacuum pump and recovery compressor, and slowly open the valve of the vacuum pump and the inlet and outlet valves of the recovery machine;

[0042] Step 2, commissioning: start the liquid supply pump, adjust the return valve to make the pressure gauge at 5.5kg / cm2;

[0043] Step 3, weighing the gas cylinder: put the gas cylinder on the scale, and record the tare weight, serial number and electronic tag number of the gas cylinder;

[0044]Step 4, liquid filling: connect the liquid filling pipe, first open the vacuum valve, evacuate the liquid filling pipe for 9 seconds, then open the gas cylinder valve to evacuate the gas cylinder for 6 minutes, then close the vacuum, open the cylinder valve and pipeline liquid filling hand valve to carry ...

Embodiment 2

[0049] Embodiment 2: A filling process for a refrigerant gas cylinder, which differs from Embodiment 1 in that it specifically includes the following steps:

[0050] Step 1, start up: first turn on the main power switch, turn on the cooling water circulation system, then turn on the vacuum pump and recovery compressor, and slowly open the valve of the vacuum pump and the inlet and outlet valves of the recovery machine;

[0051] Step 2, commissioning: start the liquid supply pump, adjust the return valve to make the pressure gauge at 5kg / cm2;

[0052] Step 3, weighing the gas cylinder: put the gas cylinder on the scale, and record the tare weight, serial number and electronic tag number of the gas cylinder;

[0053] Step 4, liquid filling: connect the liquid filling pipe, first open the vacuum valve, evacuate the liquid filling pipe for 8 seconds, then open the gas cylinder valve to evacuate the gas cylinder for 4 minutes, then close the vacuum, open the cylinder valve and pipe...

Embodiment 3

[0058] Embodiment 3: a filling process of a refrigerant gas cylinder, which differs from Embodiment 1 in that it specifically includes the following steps:

[0059] Step 1, start up: first turn on the main power switch, turn on the cooling water circulation system, then turn on the vacuum pump and recovery compressor, and slowly open the valve of the vacuum pump and the inlet and outlet valves of the recovery machine;

[0060] Step 2, debugging: start the liquid supply pump, adjust the return valve, and make the pressure gauge at 6kg / cm2;

[0061] Step 3, weighing the gas cylinder: put the gas cylinder on the scale, and record the tare weight, serial number and electronic tag number of the gas cylinder;

[0062] Step 4, liquid filling: connect the liquid filling pipe, first open the vacuum valve, evacuate the liquid filling pipe for 10 seconds, then open the gas cylinder valve to evacuate the gas cylinder for 8 minutes, then close the vacuum, open the cylinder valve and pipeli...

Abstract

The invention discloses a filling process of a refrigerant gas cylinder, and relates to the technical field of refrigerant filling. The problem that a large amount of refrigerant is wasted during repeated filling due to the fact that part of refrigerant remains in a pipeline in the filling process is solved. The gas cylinder is connected with a liquid filling pipe, a vacuum valve is opened firstly, the liquid filling pipe is vacuumized for 8-10 s, then a gas cylinder valve is opened to vacuumize the gas cylinder for 4-8 min, then vacuum is closed, a steel cylinder valve and a pipeline liquid filling hand valve are opened for filling, after liquid filling is completed, the gas cylinder valve is closed, a recycling valve is opened for 8-16 s, residual liquid in the liquid filling pipe is recycled, then the liquid filling pipe is dismounted, after repeated filling is completed according to the above operation, a choke plug is screwed on the liquid filling pipe, and all instruments and valves thereof are closed. According to the filling process of the refrigerant gas cylinder, in the actual use process, the refrigerant remaining in the pipeline can be recycled in time, the situation that a large amount of refrigerant is wasted during repeated filling is avoided, and the whole good application effect is achieved.

Description

technical field [0001] The invention relates to the technical field of refrigerant filling, more specifically, it relates to a filling process of refrigerant cylinders. Background technique [0002] Refrigerants, also known as refrigerants, refrigerants, and refrigerants, are the medium substances used in various heat engines to complete energy conversion, and the delivery of refrigerants is mainly carried out by tank trucks, and they are filled into small packages at the subpackaging plant, and then circulated to the market, and filling operations are required in the process. [0003] In the Chinese invention patent application document with the publication number CN106439481A, the refrigerant gas cylinder filling process within 1 liter is disclosed, which is carried out according to the following steps: 1) first vacuumize the gas cylinder, and then fill in a small amount of refrigerant gas to be filled Eliminate the vacuum; 2) Then evacuate the gas cylinder again, and the...
