Tank is in low-voltage vacuum state all the time, to keep relative equilibrium effectively to fill speed.
11) when weigher claim weight reach default charging weight when, close the rapidly by measuring alarm device 10
Remaining nitrous oxide gas will be pumped into gas cylinder to be filled under the effect of the pressure of vacuum pressure differential in one valve 1, pipeline, is filled
Dress terminates, and has on the one hand efficiently accomplished the charging operation of electron level nitrous oxide gas cylinder, on the other hand efficiently solves and fills knot
Pollution problem caused by residual air directly discharge in pipeline is filled after beam.
12) removable cover 3 is opened, the valve that gas cylinder to be filled is carried is closed, the gas cylinder filled is disconnected from system
Take out.
3rd, alarming step：
During cylinder filling, when weigher claim weight exceed default alarm threshold value when, by measuring alarm device
10 the first valves 1 of rapid closing, meanwhile, alarm is carried out by measuring alarm device 10, is sounded the alarm in the present embodiment
And warning indicator light is lighted, maintenance is repaiied to remind operating personnel to carry out looking into time, the security of operation is lifted.
The utility model protection be residual air in provided electron level nitrous oxide cylinder filling and pipeline processing system
The construction of system, the above implements row and does not constitute restriction to the utility model, and relevant staff is without departing from the utility model technology
In the range of thought, carried out it is various change and modifications, all fall within protection domain of the present utility model.
