Body is discharged, while the temperature in signal piping;After temperature is down to setting value in pipeline, air bleeding valve is closed, opens liquid feed valve, liquid
Nitrogen flows into the container for receiving liquid nitrogen by main line and inlet tube from liquid inlet joint.The technical solution, by the pipe that exhaust is arranged
Road discharge is higher than setting value gas so that liquid nitrogen feed liquor is more smooth, safe, reduces the liquid nitrogen volatilization in container.
Preferably, the end of exhaust pipe is provided with silencing apparatus.The noise generated for reducing exhaust.
Preferably, it is provided with safety valve on main line.If liquid feed valve and air bleeding valve are turned off, and on the container of offer liquid nitrogen
The valve of setting is also switched off, then main line, portion discharge pipe and part inlet tube form enclosure space, if the enclosure space is residual
There are liquid nitrogen, liquid nitrogen gasification causes pressure in pipeline excessive, easy tos produce explosion.There is safety valve in the structure of the preferred embodiment,
For pressure release, ensures that the pressure in pipeline will not cause stress superelevation, risk of explosion occurs.
Preferably, liquid feed valve and air bleeding valve are solenoid valve.Solenoid valve can be conveniently operated and batch pipeline with Electronic control
Remote management.
It is further preferred that manual inlet tube is also associated on main line, the end of manual inlet tube and the end of inlet tube
End is connect by a three-way connection with liquid inlet joint, and hand-operated valve is provided on manual inlet tube.When unregulated power under use environment
When configuration, solenoid valve can not be operated, liquid nitrogen can be supplemented into container by manual inlet tube by operating hand-operated valve.
In conclusion by adopting the above-described technical solution, the utility model has the beneficial effects that:
1. the pipeline discharge by the way that exhaust is arranged is higher than setting value gas, liquid nitrogen volatilization is reduced.
2. safety valve is arranged on main line, it is used for pressure release, ensures that the pressure in pipeline will not cause stress superelevation, occurs quick-fried
Fried risk.
3. setting solenoid valve can be conveniently operated the remote management with batch pipeline with Electronic control.
4. when unregulated power configures under use environment, solenoid valve can not be operated, it can be by operating hand-operated valve, by manual
Inlet tube supplements liquid nitrogen into container.
