Described valve 48, valve 38, valve 41 and valve 43 are air water mixed flow vacuum valve.
The course of work of the present invention is following:
During work, fill water in the degassing bottle 47, water level is to the b position, and is anhydrous in the graduated cylinder 45.True valve 41 is closed; Vacuum pump 49 starts; Valve 38,48 is opened, and gas gets into degassing bottle 47 through cold filtration device 42, vacuum valve 43, four-way 51 in the abradable seal jar 37, and water gets into graduated cylinder 45 in the degassing bottle 47 under vacuum pump 49 suction functions; Water level is during to c, and water levels are in a position in the degassing bottle 47.Can calculate the gas flow of deviating from this moment through SEA LEVEL VARIATION in the graduated cylinder 45.Vacuum valve 43 is closed then, and vacuum valve 41,48 is opened, and gas is discharged into gas collection bag 40 in the degassing bottle 47.Carry out above process so repeatedly, accomplish after the several times degassing, the exhaust, the addition of each amount of gas evolved accumulative total, conversion can be obtained total amount of gas evolved.
The water level of graduated cylinder 45 is determined by differential pressure pickup 46 and draws after being converted into height of water level behind the pressure reduction, also can obtain through other sensors of measuring heights of water level such as electromagnetism chis.
The vacuum tightness that vacuum sensor 44 is used to measure degassing bottle 47 is to check its impermeability.
