In of the present utility model being embodied as, the pipeline between low temperature check-valves and low temperature quick action emergency valve b is enterprising
One step is provided with Pressure gauge b7 and pressure transmitter b8；
In of the present utility model being embodied as, described low temperature immersed pump model is 18m3/h。
In of the present utility model being embodied as, the model that described all low temperature valves use is DJ61F-40P, a diameter of
50 and 40mm；The model of all relief valve is DA21F-40P, a diameter of 10mm.
Operation principle of the present utility model:
Use front pre-cooling, open low temperature quick action emergency valve a the most successively, low temperature quick action emergency valve c, other valves are in pass
Closed state, carries out immersed pump pre-cooling work.
Pressurization stages, opens low temperature quick action emergency valve a, low temperature other valve of quick action emergency valve b is in closedown the most successively
State, liquefied natural gas is flowed in the pipe network of downstream by low temperature immersed pump.
Whole device arranges relief valve, and when conduit line pressure reaches setting value, release opened by relief valve, it is ensured that system
Safety.
