FACILITY FOR DOSED INJECTION OF CRYOGENIC LIQUID AND ITS CONTROL SYSTEM Russian patent published in 2012 - IPC F17C9/00 G01F11/00 

FIELD: machine building.

SUBSTANCE: facility for dosed injection of cryogenic liquid dosing container 2 is connected to dosing valve 9. The inlet of cryogenic liquid evaporator 15 through line 14 of cryogenic liquid supply to evaporator 15, valve 13 of supply of cryogenic liquid to evaporator 15 and constantly open valve 3 of discharge of the cryogenic fluid is connected to feeder capacity 1. One output of the evaporator 15 through the gas inlet is connected to receiver 10 and the other exit of gas through nozzle heaters 16 and 17 is connected to the area around the outlet of dosing valve 9. Output receiver 10 through valve 11 of pressurisation gas supply is connected to the gas cavity through metering container 2. Receiver 10 is equipped with sensor 12 of gas pressure boost. Control system of cryogenic liquid injection dosage contains sensor 19 of the speed of a bottling line, set point device 20 of threshold values of the speed of bottling lines, light sensor 18, as well as the comparison and coincidence schemes, coupled with sensors and valves to ensure the operation of valves.

EFFECT: use of the invention allows for the possibility of a guaranteed dosage injection of cryogenic liquid at speeds of bottling lines both below and above the threshold value.
